Abstract

The utility model relates to an unilateral bearing motor, including motor shell and motor shaft, the inside rotor that is equipped with of casing, just at inside bearing and the connecting plate of being equipped with of the one end of casing, the neck at the casing is fixed to the connecting plate, with a casing edge formation cavity, be equipped with in the cavity the bearing, the bearing housing is on the motor shaft, and both ends are fixed bearing inner race on the motor shaft through the axle sleeve respectively. Simple structure, simple to operate, connection are reliable, prevent motor shaft axial float in bearing inner race.

Description

A kind of single side axis bearing motor

Technical field

The utility model relates to a kind of bearing electric machine, is specifically related to a kind of single side axis bearing motor, belongs to machine field.

Background technology

Motor shaft is supported and rotation by two oiliness bearings, and oiliness bearing is the one in bearing, extensive use in micro machine and transmission mechanism field, and oiliness bearing adds once oil can use the long period, is usually used in refueling inconvenient occasion. With its low cost of manufacture, easy to use, be widely applied, now become the various industrial products such as automobile, household electrical appliances, stereo set, office equipment, agricultural machinery, precision optical machinery and developed an indispensable class fundamental parts. In its people build, play a part more and more important. The larger motor of moment is in bringing onto load running, due to stressed larger impact, now bearings at both ends and axle produce hard grind wiping, be stressed and friction to affect dead eye increasing, the wearing and tearing of oiliness bearing endoporus are very fast, motor oscillating strengthens gradually, and the noise of motor is also increasing, thereby reduces the life-span of motor. Improving and extend the operation of motor bearings hole wearing and tearing raising electrical machinery life is the research emphasis of current machine field.

Summary of the invention

The purpose of this utility model is to provide a kind of single side axis bearing motor, and bearing is pressed into by axle sleeve, and motor is in service has reduced the brearing bore wearing and tearing of main force side, thereby has reduced the vibration of motor later stage, improves service life.

For achieving the above object, the utility model provides a kind of single side axis bearing motor, comprise motor case and motor shaft, described casing inside is provided with rotor, and is provided with bearing and connecting plate in the inside, one end of casing, and described connecting plate is fixed on the neck of casing, form a cavity with envelope edge, in described cavity, be provided with described bearing, described bearing holder (housing, cover) is on motor shaft, and two ends are fixed on bearing inner race on motor shaft by axle sleeve respectively. Simple in structure, easy for installation, connect reliably, prevent motor shaft axial float in bearing inner race.

Further improvement of the utility model is: described bearing is ball bearing.

The beneficial effects of the utility model are: bearing inner race are close to motor shaft, prevent its axial float, and ball bearing anti-wear performance are good, and long service life, good heat dissipation effect, therefore make motor have the features such as vibration is low, noise is little, long service life.

Brief description of the drawings

Fig. 1 represents the structural representation of embodiment;

Drawing reference numeral: 1-casing, 2-connecting plate, 3-bearing, 4-axle sleeve one, 5-axle sleeve two, 6-rotor, 7-motor shaft.

Detailed description of the invention

In order to deepen, to understanding of the present utility model, below in conjunction with drawings and Examples, the utility model to be described in further detail.

By reference to the accompanying drawings 1, the utility model proposes a kind of single side axis bearing motor, comprise motor case 1 and motor shaft 7, described casing 1 inside is provided with rotor 6, and is provided with ball bearing 3 and connecting plate 2 in the inside, one end of casing 1, and described connecting plate 2 is fixed on the neck of casing 1, form a cavity with casing 1 edge, in described cavity, be provided with ball bearing 3, ball bearing 3 is enclosed within on motor shaft 7, and two ends are fixed on bearing inner race on motor shaft 7 by axle sleeve respectively.

Ball bearing 3 is installed, the method that connecting plate 2 is riveted by cross is fixed in motor case 1, and connecting plate 2 is pushed down bearing outer ring, rotor 6 and axle sleeve 25 are arranged in motor stator bearing, after completing, final assembly press-fits fixing ball bearing inner ring by axle sleeve 1, bearing inner race two ends are fixing by axle sleeve 1, axle sleeve 25, prevent motor shaft 7 axial float in bearing inner race.

The utility model is simple in structure, easy for installation, connection is reliable, and ball bearing anti-wear performance is good, long service life, and good heat dissipation effect, therefore make the features such as motor oscillating is low, noise is little, long service life, has good market prospects.

The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure transformation that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
