  1. PRODUCT OVERVIEW • Gears and gear boxes • Belts & chain drives • Linear assemblies • Coupling and clutches

  2. Gears and Gears boxes

  3. Gears and Gears boxes Primary Uses: • Change Speed • Increase Torque • Transfer Rotational Motion Secondary Uses: • Change Rotation • Connect Shafting • Convert Rotational Motion to Linear Motion

  4. What is Horsepower? • A Unit of Measure for A Rate of Work (Over a Period of Time) • HP = Torque X RPM/63,025 (Lb.In.) • kW = Torque X RPM/9550 (Nm) • 1HP = 36 Lb In Torque @ 1750RPM • 1kW = 6.4nm Torque @ 1500RPM

  5. R=A P What Is Torque? • A Force That Produces or Tends to Produce Rotation • A Force Times a Distance (Radius) • Lb In. = HP X 63,025/RPM (Imperial) • Nm = kW X 9550/RPM (Metric) Torque = P x R = HP x 63000 RPM

  6. What is Ratio? • Relationship of Input to Output Rpm • # Teeth in Gear / # Teeth in Pinion
