CN204967515U - Rotor shaft internally splined sleeve structure for motor - Google Patents

Abstract

The utility model relates to a motor field of making discloses a rotor shaft internally splined sleeve structure for motor, including end links, cage strip, rotor punching, internally splined sleeve, axle, round pin, the rotor punching is fixed epaxial, and internally splined sleeve sets up the one end at the axle, internally splined sleeve is fixed through the round pin with the axle. The utility model discloses resolve into axle and internally splined sleeve two parts to integrative internal spline axle, has reduced the processing degree of difficulty of motor internal spline axle effectively, have the function reliably, simple structure, simple to operate and have the advantage of higher economic nature.

Description

A kind of rotor for electromotor axle inner spline housing structure

Technical field

The utility model relates to the field that motor manufactures, and is a kind of rotor for electromotor axle inner spline housing structure specifically.

Background technology

The equipment such as coal mine underground coal mining machine, development machine, conveyer, conventional configuration explosion separation motor is all by shaft coupling transferring power, and the connecting axle major part of shaft coupling all adopts external splines pattern, so just requires that rotor axis of electric must be internal spline structure.One female splined shaft structure fabrication process is complicated, and cost is high, and internal spline surface hardening is difficult, and sometimes case hardness does not reach designing requirement, and user in use the situation of scroll key can occur and cause motor not use.

Utility model content

In order to solve the problems of the technologies described above, the utility model discloses a kind of rotor for electromotor axle inner spline housing structure, concrete technical scheme is:

A kind of rotor for electromotor axle inner spline housing structure, is characterized in that: comprise end ring, cage bar, rotor punching, inner spline housing, axle, pin; Rotor punching is fixed on axle, and inner spline housing is arranged on one end of axle; Described inner spline housing and axle are fixed by pin.

The utility model resolves into axle and inner spline housing two parts the female splined shaft of one, efficiently reduce the difficulty of processing of motor internal spline axle, because the female splined shaft structure be integrated is as figure, needs processing in the middle of whole axle to portal, use broaching tool that internal spline is pulled out.Meanwhile, the female splined shaft of one is long, internal spline surface hardening difficulty, and sometimes case hardness does not ensure designing requirement, just easily damages in user uses.

The utility model has the advantages that:

1. the female splined shaft of one is resolved into axle and inner spline housing two parts;

2. axle and inner spline housing manufacture respectively, reduce complexity and the difficulty of manufacturing process;

3. connect with pin, structure is simple;

4., if in use internal spline damages, inner spline housing can be changed separately;

5. manufacturing cost and maintenance cost are all low.

Accompanying drawing explanation

Fig. 1 is a kind of rotor for electromotor axle inner spline housing structure diagram;

Fig. 2 is original one female splined shaft structure chart;

Fig. 3 is the structure chart of inner spline housing;

Fig. 4 is the left view of Fig. 3;

Wherein:

1, be end ring cage bar; 3 is rotor punching; 4 is axle; 5 is inner spline housing; 6 is pin, and 7 is pin-and-hole, and 8 is internal spline.

Embodiment

Illustrate the utility model below in conjunction with accompanying drawing, the utility model comprises end ring 1, cage bar 2, rotor punching 3, inner spline housing 5, axle 4, pin 6; Rotor punching 3 is fixed on axle 4, and inner spline housing 5 is arranged on one end of axle 4; Described inner spline housing 5 is fixed by pin 6 with axle 4.

In the utility model structure, the female splined shaft of one is resolved into axle and inner spline housing two parts, simplify manufacture craft, shorten Production Time, the quality of internal spline can be ensured simultaneously.In addition, due to split manufacture, therefore, female spline portion can heat treatment separately, ensure that requirement of strength, avoid existing integrally-built internal spline surface hardening difficulty, sometimes case hardness does not reach designing requirement, and user in use the situation of scroll key can occur and cause the non-serviceable technical problem of motor.

This utility model structure achieves compact conformation, manufacture craft is simple, saves time cost, has higher economy.Under the condition not affecting using function, the useful life of motor can be extended.

Claims (1)

1. a rotor for electromotor axle inner spline housing structure, is characterized in that: comprise end ring, cage bar, rotor punching, inner spline housing, axle, pin; Rotor punching is fixed on axle, and inner spline housing is arranged on one end of axle; Described inner spline housing and axle are fixed by pin.
