Efficient planet gear speed reducer with cooling function

Abstract

The invention discloses a high-efficiency planetary gear reducer with heat dissipation function, which includes an outer shell, an inner shell, a first sun gear and a first planetary gear; the high-efficiency planetary gear reducer with heat dissipation function of the present invention, through There are several heat dissipation holes on the shell wall, which can dissipate the heat in the inner shell, and a number of arc-shaped heat dissipation pipes are symmetrically arranged on both sides of the shell wall of the outer shell to discharge the heat from the heat dissipation holes, and the arc-shaped The central position of the heat dissipation pipe is bent upwards, which can prevent the water on the shell wall from flowing into the interior of the shell, and then enter the inner shell through the heat dissipation holes, and damage the equipment in the inner shell. The reducer has a high-efficiency heat dissipation function, which improves its service time, and through the driven action of the planetary gear and the sun gear, the reducer can have a high-efficiency deceleration function, good cooling effect, high deceleration efficiency, and easy promotion and use.

Description

technical field [0001] The invention relates to a planetary gear reducer, in particular to a high-efficiency planetary gear reducer with heat dissipation function, and belongs to the technical field of reducer equipment. Background technique [0002] Planetary gear reducer is also called planetary reducer, servo reducer. In the reducer family, the planetary reducer is widely used in servo motors, stepping motors, DC motors and other transmission systems by Shanghai Liyi Motor Technology for its small size, high transmission efficiency, wide deceleration range, and high precision. . Its function is to reduce the rotational speed, increase the torque and reduce the moment of inertia ratio of the load / motor under the premise of ensuring precision transmission. [0003] The main transmission structure of the planetary gear reducer is: planetary gear, sun gear and inner ring gear. Due to the structure of the planetary reducer, the minimum single-stage reduction is 3, and the m...

AI Technical Summary

Problems solved by technology

[0005] The invention proposes a high-efficiency planetary gear reducer with heat dissipation function, which solves the problem that the planetary gear reducer in the prior art needs to be shut down to dissipate heat after working for a period of time, so as to avoid the damage caused by its internal temperature being too high Appears, cannot be used for a long time, the use time is short, the heat dissipation effect is poor, and it is not conducive to the use of the problem
