High-accuracy planetary reducer integrated with motor

Abstract

The invention relates to a high-accuracy planetary reducer integrated with a motor. The high-accuracy planetary reducer comprises a double-support planetary carrier, a motor rotor shaft, a sun gear, a planetary gear and an output spline shaft, wherein the double-support planetary carrier is of a rotary structure; a gear ring is arranged at the inner side of the double-support planetary carrier; the tail end of the motor rotor shaft is in interference connection with a gear shaft of the sun gear; the planetary gear is fixed to the double-support planetary carrier; the planetary gear is engaged with the sun gear and the gear ring of the double-support planetary carrier separately; and the output spline shaft is connected to the rear end of the double-support planetary carrier. The high-accuracy planetary reducer disclosed by the invention successfully solves the problems that a large space is occupied and accuracy is difficultly increased due to split connection of a servo motor and the planetary reducer; and the overall outline dimensions of the servo motor and the planetary reducer are reduced to the greatest extent, and the working performance of the whole reducer is ensured because the motor rotor shaft and the gear shaft of the sun gear are integrated.

Description

technical field [0001] The invention relates to a high-precision planetary reducer integrated with a motor. Background technique [0002] At present, most of the workplaces where servo motors and reducers are used in the market are separate connections between the motor and the precision planetary reducer, which will inevitably increase the overall size of the servo motor and the reducer after the connection. As the space requirements are getting smaller and smaller, it is a trend to make the size of the servo motor or planetary reducer smaller. However, the split connection will still occupy a large equipment installation space, and the accuracy of the whole machine cannot be guaranteed. It is convenient for installation and transportation, which in turn will affect the processing period and production efficiency. Contents of the invention [0003] According to the deficiencies in the prior art above, the technical problem to be solved by the present invention is to prov...
