Planet speed reducer with efficient heat dissipation function

Abstract

The invention discloses a planet speed reducer with an efficient heat dissipation function. The planet speed reducer comprises an outer shell, an inner shell, a first sun gear and first planet gears.According to the planet speed reducer with the efficient heat dissipation function, a plurality of heat dissipation holes are formed in the shell wall of the inner shell so that heat in the inner shell can be dissipated; a plurality of arc-shaped heat dissipation pipes are symmetrically arranged on the two sides of the shell wall of the outer shell, so that the heat dissipated by the heat dissipation holes is discharged; the central positions of the arc-shaped heat dissipation pipes are bent upwards, the situation that water on the shell wall of the outer shell flows into the interior of the arc-shaped heat dissipation pipes, and enter the inner shell through the heat dissipation holes, equipment in the inner shell is damaged can be prevented from appearing, and the arc-shaped heat dissipation pipes have a waterproof function, so that the speed reducer has the efficient heat dissipation function, and the using time of the speed reducer is prolonged; and through the driven action of theplanet gears and the sun gears, the speed reducer can have an efficient speed reduction function, the cooling effect is good, the speed reduction efficiency is high, and the popularization and the use are facilitated.

Description

technical field [0001] The invention relates to a planetary gear reducer, in particular to a planetary reducer with high heat dissipation, 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 maximum generally does not...

AI Technical Summary

Problems solved by technology

[0005] The present invention proposes a planetary gear reducer with high heat dissipation, 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, which cannot last for a long time. Time use, short use time, poor heat dissipation effect, not conducive to use
