  • WINCH OR HOIST HAVING A GEARBOX WITH HIGH-CONTACT RATIO GEARS
    Publication number: 20250361125
    Abstract: A winch or a hoist includes an input shaft, a rotatable drum, and a gearbox including a plurality of high-contact ratio spur-type gears, the gearbox coupled to the input shaft and to the rotatable drum such that rotation of the input shaft at a first speed drives rotation of the rotatable drum at a second speed that is different than the first speed.
    Type: Application
    Filed: August 7, 2025
    Publication date: November 27, 2025
    Inventors: Brian HOLDEMAN, Daryl TOOLE
  • Winch or hoist having a gearbox with high-contact ratio gears
    Patent number: 12404155
    Abstract: A winch or a hoist (100) includes an input shaft, a rotatable drum (112), and a gearbox (120) including a plurality of high-contact ratio spur-type gears, the gearbox coupled to the input shaft and to the rotatable drum such that rotation of the input shaft at a first speed drives rotation of the rotatable drum at a second speed that is different than the first speed.

  • Encoder
    Patent number: 10942043
    Abstract: A rotary encoder may include a housing having an input-side portion and an output-side portion, and an internal cavity formed therein. The housing and its internal cavity can house a central shaft configured to transfer torque from an output shaft of a motor to an input shaft of a mechanical device such as a winch or a hoist. The housing and its internal cavity can house other components including printed circuit boards, an encoder disc, a ball bearing, and a seal.
