Abstract

The utility model relates to a cycloidal speed reduction motor which is a novel motor made by organically combining speed reduction and electromagnetic driving into one body and belongs to the technical field of electromechanical integration. The utility model is mainly characterized in that the pin gear housing and the end cap of a cycloidal speed reduction component are directly arranged on the engine base of the motor. The utility model breaks through the driving mode that a motor must be connected with a speed reducer, which has been used for centuries. Compared with the products of the German SEW company and the Lenze company and the ALTAX products of the Japanese Sumitomo company, the product shaft is shortened by twenty-five to forty percent and the weight shaft is shortened by twenty to thirty-five percent, and thereby the structure of the utility model is more compact and the utility model is more suitable to cooperate with a host machine.

Description

Speed-reducing cycloidal motor

This is novel to relate to and slowing down and the motor technical field that combines together, and a kind of do not have the cycloid speed reducer of support at the motor output end device, thereby breaks through must the connect type of belt drive of reductor of motor.

Drive in industrial application of motor invariably such as hyundai electronics, electrical equipment, medicine, food, tobacco, fine chemistry industry, five metals and weaving, but the reductor of can only connecting could use because rotating speed of motor is too high.Motor series connection reductor certainly will increase complete machine weight and strengthen axial dimension, after mean that some matched host machine must have enough big axial space.The patent of invention ALTAX speed-reducing cycloidal motor of SUMITOMO CHEMICAL heavy-duty machine tool Industrial Co., Ltd release in 1993, its structure and prior art motor direct connection cycloid speed reducer there is no substantial difference, different is that two block bearings place the Cycloidal Wheel both sides on the ALTAX speed reducer output shaft, it is said axial shortening 30%.

This novel purpose is to propose the cycloid speed reducer that a kind of motor output end device does not have support, and its profile is exactly a motor, but output speed can seriation satisfies the needs of many industry.

This novel embodiment: pin wheel housing and end cap connect one with electric machine stand.This novel DS state SEW company that compares, Lenze company and SUMITOMO CHEMICAL ALTAX reducing motor, its advantage is: 1. axial dimension shortens 25～40%, weight shaft 20～35%; 2. more compact structure is more suitable for main frame supporting; 3. save metal material, reduce manufacturing cost.

Accompanying drawing is the structure principle chart of this novel (horizontal support) embodiment.Greater detail hereinafter is described.

Referring to accompanying drawing.A kind of speed-reducing cycloidal motor that constitutes by cycloid deceleration and electromagnetism transmission, wherein the cycloid deceleration mainly is made up of Cycloidal Wheel (8), needle pin (9), pin wheel housing (7), pin (11), column sleeve (10), output shaft (14), capacity eccentric bearing (12), bearing (13) and end cap (15), the electromagnetism transmission mainly is made up of support (1), stator (2), rotor (3), main shaft (4), bearing (6), (16) and front and rear cover (5), (17), it is characterized in that:

A) pin wheel housing (7) in the cycloid deceleration component is connected in electric machine stand (1) front end;

B) end cap (15) in the cycloid deceleration component connects one with electric machine stand (1) front end, and the end cap endoporus supports output shaft (14) with bearing (13);

C) electric machine main shaft (4) output assembling capacity eccentric bearing (12);

D) electric machine main shaft (4) is bearing in front and rear cover (5), (17) hole by bearing (6), (16) respectively, and front and rear cover is connected in the front and back ends of support (1) respectively.

Transmission principle: behind power connection, axle (4) rotates, the capacity eccentric bearing (12) that is contained on the axle rotates thereupon, so the needle pin (9) on Cycloidal Wheel (8) and the pin wheel housing meshes and do the planetary reduction gear motion, export by the W output mechanism deceleration that electric pin (11), output shaft (14) constitute.

This is novel can be vertical, horizontal support, can single-stage or double reduction.
