Problems solved by technology

[0002] In industrial applications, electric motors are widely used in the form of motor series reducers, so the axial size is large, heavy and expensive
"Cycloidal geared motor" (ZL 01116741) and "Middle and low speed motor" (ZL 02154608) propose to install transmission parts with less tooth difference in the machine base. It is an obsolete technology; the "built-in motor reducer" (ZL 97203564) also has a small tooth difference, and the double-layer internal meshing structure is complex and the efficiency is lower

Abstract

The invention discloses a speed reduction electric motor, namely a novel electric motor integrating an epicyclic gear train and an electric motor. The novel electric motor comprises a stander, a stator, a rotor, an internal end cover, a planet carrier, an internal gear, a sun wheel, a big end cover, a supporting bearing, an output shaft, a planetary wheel axle and a planetary wheel. The invention arranges an epicyclic gear train reducer in the stander, uses the internal end cover to separate the epicyclic gear train from an electromagnetic starter and arranges the sun wheel of the epicyclic gear train on a rotor shaft, wherein the epicyclic gear train is a quasi-planet transmission or enclosed planet differential combined gear train. The beneficial effects of the electric motor include light weight, material saving, low cost, high efficiency, small shape, simple installation and other marked advantages.

Description

technical field [0001] The invention relates to a motor and a reducer, in particular to a new type of motor. Background technique [0002] In industrial applications, motors are widely used in the form of motor series reducers, so the axial size is large, heavy and expensive. "Cycloidal geared motor" (ZL 01116741) and "Middle and low speed motor" (ZL 02154608) propose to install transmission parts with less tooth difference in the machine base. It is an obsolete technology; the "reducer with built-in motor" (ZL 97203564) also has less tooth difference, and the double-layer internal meshing structure is complex and the efficiency is lower. Contents of the invention [0003] The object of the present invention is to propose a novel motor with an output speed of n=500-30r / mm, high deceleration transmission efficiency η=0.96-0.98, and light weight, which is used to replace various speed reducers in series with the motor. [0004] The technical scheme that the present inventi...
