  • Cord Tensioning is Critical to Belt Performance
    Belt Pitch. The pitch of the belt is controlled by either increasing or decreasing the cord tension in the manufacturing process. Increasing the tension shortens the length, and decreasing makes the belt longer. Good control of pitch length requires control of tension. Belt Straightness. Uniform
  • Variable-Pitch Drives
    Variable-pitch drives are the simplest of all mechanical adjustable-speed mechanisms. Most of these drives use rubber belts. However, chain types are unmatched in regard to its particular strong points. Belt and chain adjustable-speed drives are "adjustable " in two senses. One type
  • Tension in timing-belt drives
    A urethane timing belt moves samples into position in this CAD simulation of an automated blood sampling machine. Timing-belt drives transmit torque and motion from a driving to a driven pulley or force to a linear actuator. They may also convey a load placed on the belt surface. A drive under load
  • It's a swing and a miss
    Announcers may no longer utter that statement if a concept baseball pitching machine comes to fruition. Full degree-of-freedom pitching machine featuring yaw and pitch-control frames. Stepper motor and gear belt rotate the pipe. Front view of the propulsion system consisting of an air tank, valve
  • Gear Drives
    , the mechanical type generally cannot transmit as much power as electricaldrives when variable speed is essential. The basic types of adjustable-speed drives are geared transmissions (which provide only specific fixed-speed ratios), variable-pitch belt and chain drives (which provide infinitely
  • Basics of Configuring Drives
    on gear ratios, It can be difficult to specify drive components that transform power from a motor into a form that is useful for the load. The overall design may dictate use of basic drive mechanisms such as spindles, gearing, or belts. But the motor or motor/gearing combination determines the parameters
  • Stator Stakes Claim to Top Powder-Metal Prize
    consumption and the formation of exhaust gases, and improves engine performance, especially torque at low rpms. It has two splines, one for the timing-belt pulley and one for the VVT housing. The PM part is said to be substantially less expensive to make than its two-part predecessor despite the fact
