Title:
AUTOMATIC GEAR SHIFTING AND SPEED CHANGING PLANETARY GEAR TRANSMISSION AND WINCH WHICH MOUNTS TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2018/233238
Kind Code:
A1
Abstract:
An automatic gear shifting and speed changing planetary gear transmission and a winch which mounts the transmission, comprising: an electric motor or a hydraulic motor (1), a transmission (2), a gear shifting mechanism (3), a reel (4), a brake (5), a machine frame (6) and so on; an end portion flange of the electric motor or hydraulic motor (1) is mounted to one end of the machine frame (6) by using a bolt; a hollow electric motor rotor shaft (1.1) or a hydraulic motor power output shaft (1.1) is provided therein with an internal spline (1.1a) which is in clearance fit with an external spline (2.1a) of an end portion of a transmission drive shaft (2.1); during gear shifting, the drive shaft (2.1) may linearly reciprocate in the electric motor rotor shaft (1.1) or the hydraulic motor power output shaft. The planetary gear transmission and the winch have simple structures, are small in volume, have large torque, have high transmission efficiency, and may shift gears and regulate speed according to load, thereby saving energy.
