Abstract
The utility model discloses an electric machine bearing arrangement structure. Not an escrape groove but a washer is provided in the connecting position of the bearing arrangement position and the shaft shoulder so that the shaft diameter reduction and stress concentration are not generated in the bearing arrangement position because of the arrangement of the escrape groove in the axle. The benefit effect of the utility model is to improve the axle strengthen of the bearing arrangement position and to improve the loading capacity of the electric machine axle.
Description
Technical field
The utility model relates to a kind of motor bearings mounting structure.
Background technology
At present, known motor bearings mounting structure has the Bearing Installation position and the shaft shoulder on motor shaft, for the convenience that makes bearing can be close to the shaft shoulder and process, on the Bearing Installation position that links to each other with the shaft shoulder, have escape, this escape diminishes the diameter of axle of Bearing Installation position and forms stress and concentrates, make the strength reduction of escape place axle, this position is caused fatigue fracture easily when the motor heavy-duty service, and this is its shortcoming.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of motor bearings mounting structure that can improve motor shaft intensity.
The technical scheme that its technical problem that solves the utility model adopts is: do not open escape in Bearing Installation position and shaft shoulder junction, but between the shaft shoulder and bearing, add a packing ring, so just can the diameter of axle of Bearing Installation position be diminished and to form stress concentrated because of having held escape on the axle.
The beneficial effects of the utility model are to improve the axle intensity of motor bearings installation site, raising motor shaft load capacity.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a motor bearings mounting structure schematic diagram of the present utility model.
Fig. 2 is the motor bearings mounting structure schematic diagram of prior art.
1. motor shafts among the figure, 2. packing ring, 3. bearing, 4. Bearing Installation position, the 5. shaft shoulder, 6. escape.
Execution mode
Motor bearings mounting structure of the present utility model has the shaft shoulder 5 and Bearing Installation position 4 on motor shaft 1, bearing 3 is installed on Bearing Installation position 4, it is characterized in that: between the bearing 3 and the shaft shoulder 5 packing ring 2 is arranged, the external diameter of packing ring 2 is not more than the external diameter of bearing 3 inner rings, the internal diameter of packing ring 2 and motor bearings installation site 4 can be movingly a kind of, interference fits or stationary fit, for ease of installation and removal, to be advisable movingly, the thickness of packing ring 2 can be according to the flexible in size configuration of axle, for packing ring 2 and the shaft shoulder or bearing are close to, can leave a certain size chamfering within it on the circle.
Because packing ring 2 has been arranged, needn't as Fig. 2, leave escape 6 in the motor bearings mounting structure, can overcome the shortcoming that the Bearing Installation position diameter of axle that causes because of escape diminishes and causes stress to concentrate like this, improve the intensity of motor shaft.
