Abstract

The invention discloses a back-clearance-free transmission method for a large high-precision rotating disc. One servomotor is used for driving a worm gear reducer which serves as a primary reducer; two output ends of the reducer is connected with an input end of a secondary reducer through a connecting shaft and an expansion sleeve; pinions are mounted on two output ends of the secondary reducer respectively and meshed with slewing bearing outer ring gears, so that the rotating disc mounted on a slewing bearing outer ring is driven to slew; module numbers and pressure angles of the pinions and the slewing bearing outer ring gears are equal; and a slewing bearing internal annular gear is fixed on a turnover disk. The expansion sleeve is adjusted, so that mechanical clearance of transmission in two directions between the servomotor and the rotating disc can be eliminated, and the transmission precision is improved; a center distance adjusting mechanism is mounted on the turnover disk and used for adjusting a center distance between a pinion on the output shaft of the secondary reducer and a slewing bearing outer ring gear, and the gear mesh accuracy is improved.

Description

technical field [0001] The invention relates to a backlash-free transmission method for a large-scale high-precision turntable. The method can eliminate the mechanical backlash in the positive and negative directions during the rotation, and is suitable for high-precision, multi-degree-of-freedom transmission of workpieces installed on the turntable. Measurement and processing to ensure the transmission accuracy requirements. Background technique [0002] In the measurement and processing of the workpiece, the high-precision, large reduction ratio, and multi-degree-of-freedom turntable are usually used to install the measured workpiece on the turntable to measure and process the workpiece. In the whole transmission, from the motor to the final end of the transmission, all mechanical transmission backlashes in positive and negative directions determine the rotation accuracy of the turntable, so an anti-backlash mechanism must be used to meet the precision requirements of the ...
