Concept of slewing bearing 1) Definition Slewing bearing is a large bearing with special configuration, which can endure biggish multiply load, such as axial & radial load, overturning moment, etc. 2) Structure Slewing bearing is composed of outer ring (teeth or non-teeth), rolling element (steel ball, cylindrical roller, tapered roller), cage, inner ring (teeth or non-teeth) and seals (the one with sealed structure). 3) Classification Slewing bearing can be classified by different structure: four point contact ball slewing bearing; double – row different diameter ball slewing bearing; cross roller slewing bearing; three – row roller slewing bearing, etc.Slewing bearing also can be classified by teeth: slewing bearing with non-teeth, slewing bearing with external teeth, slewing bearing with internal teeth. 2. Function and characteristic of slewing bearing 2.1 Function Slewing bearing itself is featured in compact structure, convenient lead to slew, easy for installation & maintenance, which is widely used as slewing set in the fields of heavy machine, slewing platform in the steelworks, excavator grab, material taking & stacking set, material traveler, harbor machine, missile launching cage, CT set, etc. 2.2 Characteristic 1) Four point contact ball slewing bearing can take more dynamic load, and suitable for the application with speed. 2) Cross roller slewing bearing can take more static load, it’s pre-interference is better for more support rigidity and slewing precision. 3) Three – row roller slewing bearing is a high load capacity slewing set, different direct raceway and rollers can take load from different side. So when have the same load, it can be smaller size that can make the application compact. 3. Choosing type How to choose the slewing bearing type to suit the application best? Most of the companies chooses slewing bearing depends on the load chart. Most of slewing bearings work under eccentric load, take axial load (Fa), radial load (Fr) and overturning moment (M). So before choosing a suitable bearing need to have calculation for the bearing using condition, need to calculate the load for dynamic and static condition. Calculating the service life according to the safety factor of different application. Then may choose the suitable bearing. 2797/2680K slewing bearing load curve Curve 1 means when material is 42CrMo, it is the allowable static load curve for ball bearing with allowable contact stress 3850Mpa, or roller bearing with allowable contact stress 2700 Mpa. Curve 2 means rated dynamic load curve when bearing has whole turning with reliability 90%, life time 0.03×106, under condition of not high radial load, low speed of turning and not high working precision. Curve 3 means when material is 50Mn, it is the allowable static load curve for the ball bearing with allowable contact stress 3400Mpa, or roller bearing with allowable contact stress 2100Mpa. The maximum load curve of the bolt is when its joint length is five times long as the bolt diameter, and the preliminary stress is 10% of the yield strength of the material. wechat: 17702586093 Skype: youlite2016 QQ：2940894886

Lubrication & seal of slewing bearings It is necessary measure to lubricate & seal bearings effectively and sufficiently for ensuring bearings’ safety operation and avoiding early abnormal damage. 6.1 Lubrication of bearings Slewing bearings are usually operating in high-load & low-speed working condition, it is recommended to fill lubricate grease to do a good job. There are kinds of lubricate grease widely used, such as calcic lubricate grease, lithium lubricate grease, aluminum lubricate grease, high temperature lubricate grease, etc. Customer could choose the most suitable lubricate grease based on actual condition. It is listed with recommended lubricate grease types in form 7. 6.2 Seal of slewing bearings The seal of slewing bearings is used for avoid leakage of filled lubricate grease on one side, and the other side is to avoid in-leakage of outer dust, impurity and water which can cause abnormal operation of slewing bearing. As slewing bearing is operating in the condition of high-load & low-speed, there are two seal structures usually used, rubber and labyrinth. Rubber is widely used because of simple structure, little space occupied, good seal capability. But it will aging easily at high temperature and lose seal capability. So it is recommended to use labyrinth when in the high temperature condition.

The following factors are keys: ·Torque ·Output speed ·Duty factor ·Ambient temperature ·Lubrication etc. 9. Inspection to rings Inner & outer diameter size, height, magnetism remained, thickness of the raceway for ball, central diameter of the mounting holes, space between holes. For those with outer teeth should also inspect teeth height, constant cord thickness, etc. 10. Package & storage of slewing bearings 10.1 Package of slewing bearings Every slewing bearing before delivering to customers should be packed well,of which inside,outside surface and raceway are spreaded with antirust&lubricate grease.Inner package is made of plastic film,and then compositive kraft,outer package is enlaced with flax pieces. 10.2 Storage of slewing bearing WCB slewing bearings are well treated with antirust and oil seal before delivery, which can ensure non-rust in 12 months in the normalstorage condition. When slewing bearings are in antirust period, they can be stored when their original package is in good condition. Asto the storage is in excess of antirust period, slewing bearings should be treated with cleanout and oil seal again. Slewing bearings should be placed horizontally in a dry breezy flat field, which are away from chemical and other erosive things. If slewing bearings are piled up for storage, it’s necessary to use at least three stow-wood in equal height, which are equally placed between every slewing bearing, and their location between up & low level should be consistent。 11. Installation & Maintenance of slewing bearings 11.1 Installation of slewing bearings Before installation of every set of WCB slewing bearings, it’s necessary to check the host installation plane. Make sure that the supportpart has enough rigidity, and it should be mechanically processed in order to remove the sundries and burrs.

Soft belt should be located in non-loading area or non-regular loading area (Where filler plugs locate) during installation. Installation should be begun with slewing bearings’ radial location, screw down the mounting bolt and check the slewing condition. In order to ensure the slewing steadiness of bearings, gear mesh checking is needed before screwing down the bolt completely. It should has enough preload when screwing down the bolt, which should be 70% of yield strength of bolt material. Mounting bolt should be used with Q & T flat gasket not spring gasket. The fastening bolt must reach the required preload when assemble the slewing bearing. Preload of different diameter bolt should accord with Form 11.

Since the first check, it should be repeated every 500 working hours. After installation, some lubrication grease should be filled into bearings, when doing this, remember to slew the bearings in order to ensure grease equal arrangement. It’s normal for slewing bearings to lose some lubrication grease after working for some time, so grease refilling is necessary for working slewing bearings once every 50~100 working hours. This period should be reduced in the working condition of high temperature and dust. This refilling is also needed when machine stops turning for some time.

Repair or refurbishment is usually only economic on slewing ring with large bore size and depends on the degree of wear or damage. Repair on smaller slewing rings is possible, but only becomes economic on larger batch sizes. Certain types of damage are easy to repair, such as minor surface scuffing or light staining. Moderate surface conditions, such as corrosion, indentation of fine spalling, and more difficult to repair and will probably require raceway grinding. Also some bad condition we have to change the rollers/balls and cage, re-grinding on the raceway and surface. It all depends on the status of the slewing rings. So if you want to repair on your slewing ring, please contact with us to show the condition of the slewing rings and better the photos to let us check if can be repaired and give you the repair suggestion on this. Before repair 1, Send us the details status of the slewing ring (bearings), include photo and drawing 2, We will see if we can repair or not, if needed we will send engineer to check. 3, Send customers repair plan and rough cost 4, Customer send us the old slewing rings (bearings) After repair 5, After receiving, we may clean, measure and give you the detailed test report and exact cost. 6, Repair according to plan, and if some old parts can not be used, we may do the new one. 7, When finish, customer can come to factory to inspect. 8, Send good finished ones to customers.

Slew drive must be installed on a hard horizontal surface, and the bolts of the firm steps must be tightened in case of loosen and abnormal vibration; remove painting residues, burr and extraneous material to make sure installing datum plane and bracket surface flat. To prevent local overload of slew drive and ensure its flexible running, mounting bracket shall be eliminated internal stress and done mechanical treatment after welding processes. Flatness(including horizontal angle deviation) should be controlled in a certain range. 2. The special bolts size for slew drive should be in keeping with the standard GB/T5782-2000 and GB/T5783-2000 of the People’s Republic of China, the bolts strength grade should reach the national standard GB/T3098.1-2000 regulations of grade 8.8. (1) washer size should be in keeping with the standard GB/T1230-2006 and standard GB/T123-2006. Spring washer is not used; the washer should be required quenching and tempering and selected correct strength grade based on the load of slew drive. (2) Nut size should be in keeping with the standard GB/T6170-2000 and standard GB/T6175-2000 of the People’s Republic of China. The mechanical properties should be in keeping with the national standard GB/T3098.2-200 regular of the People’s Republic of China. (3) Tighten bolts should be pre load tightening force according to mainframe design rules, unless there are special provisions, general tightening force for pre loading should be 70% of bolt yield limit, screw thread is allowed to oil in small quantity when it is tightened.

Maintenance Maintenance Maintenance Maintenance instructions instructions instructions instructions for for for for slew slew slew slew drive drive drive drive 1. According to JBT2300-1999, slew drive should be oiled in small quantity of lithium base grease before delivery, please check and oil new grease in the different operating condition before installing. 2. Relubrication intervals mainly depend on the prevailing work and environmental conditions as well as on the version of the slew drive. The following table can be used for a reference value. Slew drive shall generally be relubricated before and after long inactive periods. While rotating the slew drive, inject grease into all the cleaned grease nipples consecutively until a bead of fresh grease spills from seal and the grease fills in the raceway equably. Working condition Torrid zone, high humidity, dusty, big temperature difference and continuous working Extreme condition Normal working condition 3. It is necessary to clear the sundries on the surface of slew drive away and check whether seal is aged, dissilient, breakage or loose. If any one of above conditions happens, please replace new seal to prevent sundries getting into raceway and running grease off, then relubricate grease to avoid corrosion of roller and raceway. 4. Grease types can be determined under actual operating conditions by customer, for example: raceway can be lubricated by 3#,4# graphite, industry grease, 203# grease, 7002# bearing grease and 2# aluminum base grease and so on. It is necessary to check the pre-load of bolt to keep enough pre-load after first 100 hours in operating. And this inspection shall be repeated after every 500 hours. 5. After 2000hours in operating, if any bolt looses m,ore than 20% torque, please replace the bolt and two neighbors, if 20% of bolts loose more than 20%, please replace all the bolts. After 14000 hours in operating, replace all bolts, nuts and washers with new ones. 6. It is necessary to give close attention to operating condition, in case of increasing noise, impact or power suddenly, it should be fixed until clearing all the faults. If necessary, dismantle the slew drive, clean and check it. Lubrication intervals Every 50 hours Every 75 hours Every 150 hours QQ：2940894886 wechat: 17702586093 Skype: youlite2016

None of their parts is susceptible to wear. Each turntable consists of two steel rings designed for flange mounting. The raceways are machined so as to ensure that the load transmission is favorable directed between the antifriction bearing steel balls that are fitted. An initial filling of grease protects the raceway system. WCB supply included: ·Standard/ Low-maintenance ·Drilled/ Undrilled ·Primed The turntables are supplied as either undrilled or drilled bearings with the standard type being filled with lithium-saponified grease and the low-maintenance type. Every turntable is coated with a primer and can therefore be painted at the same time as the trailer. The primer is based on a synthetic resin compound.
