Title:
ZERO BACKLASH RIGHT ANGLE TRANSMISSION SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2017/012558
Kind Code:
A1
Abstract:
A zero backlash right angle transmission system and a method for zero backlash right angle transmission, the transmission system includes an input shaft (109) with an input gear (106), an output shaft (101), first and second drive gears (107,108) mounted on respective drive shafts (122,123) and meshing with the input gear (106), and first and second pairs of meshing gears (102,103,104,105), rotation axes of which are disposed at right angle to each other. One of the pair of meshing gears is mounted on the drive shaft and the other one is mounted on the output shaft. The system may also includes first and second planetary gear assemblies. All of the gears form a closed loop gear train that drives the output shaft forward and backward without backlash. The transmission system can eliminate backlash of small motor, thus to increase torque with the presence of feedback position control of high bandwidth.
