A separate servo turntable transmission device with adjustable backlash

Abstract

The invention provides a separate adjustable-backlash servo turntable transmission device comprising a base, a rotary platform, a mounting bracket, a servo motor, and a transmission device. The transmission device comprises a small gear, a reducer, and a rotary bearing with external teeth. The outer ring of the rotary bearing is fixed to the upper bottom surface of the base. The upper end of the rotary platform is provided with a loading platform, the lower bottom surface is provided with a groove, and a window is arranged between the groove and the outer wall. The rotary platform covers the rotary bearing, and is connected with the inner ring of the rotary bearing. The mounting bracket is connected with the rotary platform through a hinge shaft, and is equipped with the reducer, the small gear and the servo motor inside. The reducer is connected with the servo motor. The small gear is arranged on the output shaft of the reducer, and the small gear engages with the external teeth of the rotary bearing at the window. The transmission device provided by the invention is easy to maintain, easy to control in transmission accuracy, and reliable in structure.

Description

technical field [0001] The invention relates to the field of gear transmission devices, in particular to a transmission device for a servo turntable. Background technique [0002] As an important loading platform, the servo turntable is widely used in both military and civilian fields. The transmission device occupies an important position in the servo turntable and directly affects the performance of the servo turntable. [0003] At present, the servo motor and reducer of the servo turntable are generally fixed on the base or the rotary platform, and in order to reduce the impact of the harsh environment, they are generally installed inside a sealed cavity. When disassembling and maintaining, it is necessary to remove some external devices first, which is time-consuming Long and heavy workload. And because the servo motor and reducer cannot be separated from the rotary platform or the base, the center distance between the pinion gear installed on the output shaft of the r...

Problems solved by technology

[0003] At present, the servo motor and reducer of the servo turntable are generally fixed on the base or the rotary platform, and in order to reduce the impact of the harsh environment, they are generally installed inside a sealed cavity. When disassembling and maintaining, it is necessary to remove some external devices first, which is time-consuming long and heavy workload

And because the servo motor and reducer cannot be separated from the rotary platform or the base, the center distance between the pinion gear installed on the output shaft of the reducer and the outer gear of the rotary bearing and the side clearance of the meshing transmission cannot be adjusted, and the transmission accuracy of the servo turntable is also difficult to control
