Abstract
The utility model relates to a motor driving clutch structure, which comprises a motor shaft, an inner spline shaft sleeve and an outer spline shaft sleeve. The outer spline shaft sleeve is sleeved and limited on the motor shaft, the inner spline shaft sleeve is sleeved and meshed on the outer spline shaft sleeve; the motor driving clutch structure further consists of an elastic telescopic component disposed between a casing of a motor and the inner spline shaft sleeve; comparatively preferably, the inner spline shaft sleeve is positioned between the casing and the outer spline shaft sleeve, two ends of the elastic component are respectively abutted to the casing and the inner spline shaft sleeve; alternatively, the outer spline shaft sleeve is positioned between the casing and the inner spline shaft sleeve, the two ends of the elastic component are respectively drawn on the casing and the inner spline shaft sleeve; the elastic component is a spring; and splines of the inner spline shaft sleeve and the outer spline shaft sleeve adopt rectangular splines, involute splines or triangular splines. The structure has ingenious design, simple structure, simple and convenient manufacture, low cost and simple and convenient clutch.
Description
Technical field
The utility model relates to technical field of motors, and particularly the electric-motor-driving technical field specifically is meant a kind of electric-motor-driving clutch structure.
Background technique
The prior motor drive mechanism mainly is a sheathed spacing external splines axle sleeve on motor shaft, internal splined shaft bushing socket engagement external splines axle sleeve then, and internal splined shaft bushing is connected with the parts that will drive, thus the realization driving.But, in the machine operation process, can run into the situation that need promptly stop driven parts, this time, the most direct way was the powered-down switch, but power switch is not on hand usually, inconvenient operation, and frequent switch power are bigger to the influence of motor, and powered-down, therefore motor shaft needs to install clutch usually because inertia can not stop immediately, and stopping effect is relatively poor, thereby in needs, make the device busy that has motor and stop switching easily between the two states, but existing clutch configuration is all very complicated, makes trouble, the fabricating cost height.
Therefore, how to make the clutch of electric-motor-driving structure simple and convenient, just become the pressing issues that need solution.
The model utility content
The purpose of this utility model is to have overcome above-mentioned shortcoming of the prior art, and a kind of electric-motor-driving clutch structure is provided, and this electric-motor-driving clutch structure design is ingenious, simple in structure, manufacturing is easy, cost is low and clutch is easy.
To achieve these goals, electric-motor-driving clutch structure of the present utility model has following formation:
This electric-motor-driving clutch structure, comprise motor shaft, internal splined shaft bushing and external splines axle sleeve, described male splined shaft condom is limited the position on described motor shaft, described internal splined shaft bushing socket is engaged in described external splines axle sleeve, be characterized in, also comprise the elastic telescopic parts in the described electric-motor-driving clutch structure, described elastic telescopic parts are arranged between the casing and described internal splined shaft bushing of described motor.
Preferably, described internal splined shaft bushing is between described casing and described external splines axle sleeve, and described elastic member two ends are respectively against being arranged at described casing and described internal splined shaft bushing.
Preferably, described external splines axle sleeve is between described casing and described internal splined shaft bushing, and described elastic member two ends tractive respectively are arranged at described casing and described internal splined shaft bushing.
Preferably, described elastic member is a spring.
More preferably, described spring housing is located on the described motor shaft.
Preferably, the spline of described internal splined shaft bushing and described external splines axle sleeve is rectangular spline, involute splines or serration spline.
The beneficial effects of the utility model are specific as follows:
1, the utility model is by being provided with spring between internal splined shaft bushing and casing, make the internal splined shaft bushing socket be engaged in described external splines axle sleeve by spring force during work, when needing to throw off internal splined shaft bushing is applied pressure or tractive force, after pressure or tractive force discharge, female splined shaft is enclosed within the effect of spring force again that socket is engaged in described external splines axle sleeve, design ingenious, simple in structure, clutch is easy;
2, the utility model adopts spring to be arranged between internal splined shaft bushing and the casing, and its manufacturing is easy, cost is low.
