HOW TO ASSEMBLE BEVEL GEARS FOR OPTIMUM PERFORMANCE?

1. HOW TO ASSEMBLE BEVEL GEARS FOR OPTIMUM PERFORMANCE? A Bevel Gear box is a cone-shaped gear which transmits power between the two intersecting axels. Bevel gears can be generally classified into straight bevel gears, which do not have helix angles, and spiral bevel gears which do have helix angles. Since manufacturing facilities for straight bevel gears are becoming rare and straight bevel gears teeth cannot be polished, rendering spiral bevel gears superior in terms of noise reduction, spiral bevel gears are likely to become more common in the future. Bevel gears can be straight, spiral, zerol, and hypoid. Because the shape of these types of bevel gears is basically conical, they all have an optimal position for best performance. This optimum position is usually determined by the bevel gear manufacturers by running tests of individual gear sets. The gearbox designer and assembly technician, however, share responsibility for integrating this ideal positioning into the gearbox. In order to help the technician assemble the overall gearbox, the designer must provide shimming dimensions that are easy to measure. www.deccanew.com sales@deccanew.com

2. KEY FACTORS OF ASSEMBLING BEVEL GEAR BOXES Some parameters contribute to proper gearbox assembling that help to ensure smooth and efficient operation. They are; 1.Mounting Distance 2.Backlash 1.Mounting Distance: The distance from a locating surface on the back of one gear to the center-line of a mating gear is the mounting distance. By running the gearset and changing its position, the manufacturer calculates the optimal value for this length in order to obtain a tooth contact pattern compatible with smooth running and optimum load distribution between mating gear teeth. It is then possible to record the optimum mounting distance. Gear in a package has a unique value for the mounting distance due to dimensional differences between parts and, in most cases, the manufacturers and supplier permanently labels this value on each gear. 2.Backlash: To absorb manufacturing error and secure oil film thickness on the gear layer, backlash is required. It is the gap between the matting gear teeth or the difference in the gear tooth width and the matting gear pinion tooth. Backlash is important for proper gear operation and varies with the size of the tooth and conditions of operation. Once fully put together, the bevel gears are cut to have a certain amount of backlash. But in starting or reversing, extreme backlash or play, if great enough, can cause a sudden impulse or shock load that can cause serious damage to the tooth.
