Abstract

The utility model relates to the field of electric motor integration technology, in particular to a novel electric motor integrating deceleration and electromagnetic actuation organically, which is mainly characterized in that the pedestal of an electric motor and the pedestal of a reducer are integrated, i.e., a mutual pedestal is provided. Further, two ring walls constitute a pin gear housing in the inner cavity at the front end of the pedestal, and an oil chamber is provided at the lower end of the pin gear housing, which thereby greatly enhances the mechanical strength of the pedestal. The utility model breaks the traditional mode that for hundreds of years, the electric motor has to be connected with the reducer in series. Compared with the product shafts of German SEW, Lenze and Japanese Sumitomo ALTAX, the size is shortened by 30 percent to 45 percent, the weight is reduced by 30 percent to 40 percent, the manufacturing cost is low, and so on.

Description

Novel motor

This novel electromechanical technical field that relates to, a kind of will the deceleration organically combines the novel motor of one with Electromagnetic Drive, thereby breaks through the kind of drive of the reductor of motor series connection for hundreds of years.

As everyone knows and since main frame when supporting required rotating speed therefore must connect reductor and increase axial dimension and weight greatly generally far below motor speed, this obviously is not perfect condition for matched host machine.So both at home and abroad the researcher is devoted to dwindle the research of the overall dimension of reductor, the serial reducing motor of GST of the SEW reducing motor of for example German SEW-EURODRIVE company and German Lenze company.Its structure still belongs to the type of belt drive of motor in series reductor.The patent of invention ALAX speed-reducing cycloidal motor of SUMITOMO CHEMICAL heavy-duty machine tool Industrial Co., Ltd release in 1993, to its results of structural analysis, it and motor associated mode cycloid speed reducer there is no substantial difference, and its use power only limits to 40W～3.7KW still more.

This novel purpose is to propose a kind of mechanical, electrical novel decelerator of one that is that melts, its profile is exactly a motor, but output speed can seriation and satisfy the application need of national defence, mine, metallurgy, machinery, chemical industry, pharmacy, tobacco or the like industry greatly.The utility model motor has been broken through must the connect traditional form of reductor of motor fully.

This novel main technical application scheme is that electric machine stand, cycloid speed reducer support are combined together.Further be, cast out two annulus walls at support inner chamber output and form pin wheel housing that corresponding to the pin wheel housing below one shoe cream room is arranged, two annulus walls and shoe cream room sidewall play a part reinforcement and increase substantially the support mechanical strength.

This novel SEW company that compares, Lenze company and Sumitomo ALTAX reducing motor, its advantage is: 1. axial dimension shortens 30～45%, weight saving 30～40%; 2. more compact structure is more suitable for main frame supporting; 3. improve the lubricating status that motor output shaft holds and increase the service life greatly; 4. save metal material, reduce manufacturing cost; 5. use power bracket big, output speed can seriation.

Accompanying drawing has the example structure schematic diagram of shoe cream room for total support (1) inner chamber front end has two annulus walls formation pin wheel housing and lower end, encyclopaedizes below in conjunction with accompanying drawing:

Referring to accompanying drawing.A kind of novel motor by electromagnetism transmission and cycloid deceleration two parts organic assembling one, wherein the electromagnetism transmission mainly is made of stator, rotor, axle, end cap and bearing; Cycloid slows down and mainly to be made of Cycloidal Wheel, pin gear, W output mechanism and capacity eccentric bearing, is primarily characterized in that: electromagnetism transmission and cycloid both supports that slow down combine together, promptly have support (1).Further be that support inner chamber front end has two annulus walls both to constitute pin wheel housing, again as the reinforcement of support, and a shoe cream room (18) is being arranged corresponding to the pin wheel housing bottom, and the sidewall of shoe cream room also improves the mechanical strength of support greatly as reinforcement, wherein:

1) support (1), stator (2), rotor (3), axle (4), end cap (6) and bearing (7), (5), (20) constitute the electromagnetism transmission, end cap (6) connects with inner chamber annulus wall, axle (4) is positioned in end cap (6) endoporus by bearing (5) and all carry the ring cylindrical by bearing (7), (20), be positioned in dowel pin uniformly-loaded ring (8) and end cap (19) endoporus respectively;

2) support (1), be contained in pin tooth (10) in the uniform hole of two annulus walls, needle guard (9), Cycloidal Wheel (11), pin (12), column sleeve (13), capacity eccentric bearing (17), output shaft (14), bearing (16) and front end housing (15) and constitute the cycloid deceleration transmission, pin wheel housing is inner chamber two annulus walls, all carries the bending strength that ring (8) is used for improving pin.

Transmission principle: behind power connection, axle (4) rotates, be contained in capacity eccentric bearing (17) transmission thereupon on the axle, the gear pin on Cycloidal Wheel (11) and the pin wheel housing, cover mesh and do the planetary reduction gear motion, export by output shaft (14) deceleration of W output mechanism.Because the pectinid of aerofoil fan, temperature rise is descended.This is novel can be vertical, horizontal, single-stage, twin-stage.
