Abstract

The utility model discloses an installation improved structure of motor output shaft bearing and end cover, comprising an output shaft bearing and an end cover provided with a through hole; the inner end of the through hole is provided with a retaining wall integrated with the end cover; the inner end of the output shaft bearing is pressed against on the end face of the retaining wall; the outer end face of the output shaft bearing is fixed by an outer blocking structure disposed at the mouth end of the through hole; the outer blocking structure is plurality of radial blocking points riveting pressed by a frieze at the mouth end of the through hole. The output shaft bearing of the utility model will not move axially, so that the stable running of a motor rotor is ensured; the output shaft bearing is mounted by an outer end and passed through a riveting solid line; the structure is simple, and the installation is convenient.

Description

The improved mounting structure of a kind of Motor Shaft bearing and end cap

Technical field

The utility model relates to the improved mounting structure of Motor Shaft bearing and end cap.

Technical background

As Fig. 1, be existing a kind of common motor, it goes out in the through hole 11 that axle bearing 2 is installed in end cap 1, the through hole outer end is provided with step 12 and uses axle bearing and do not understand outer moving, going out axle bearing the inner encapsulates by jump ring in through hole, this structural disadvantages is still to occur the axial motion phenomenon easily after the Bearing Installation, influences the stable operation of rotor.

The utility model content

Technical problem to be solved in the utility model just provides the improved mounting structure of a kind of Motor Shaft bearing and end cap, and it can well avoid out axle bearing the phenomenon of axial motion to occur, guarantees rotor stable operation, and is simple in structure, easy for installation.

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: the improved mounting structure of a kind of Motor Shaft bearing and end cap, comprise axle bearing and be provided with the end cap of through hole, it is characterized in that: described through hole the inner is provided with the retaining wall with the end cap integrative-structure, describedly go out axle bearing the inner and be connected on the retaining wall end face, describedly go out the axle bearing outer face and fix by the wild card bit architecture that is located at the openings end.

Preferably, the some radially stuck points of described wild card bit architecture for going out by openings end eaves wall riveting.

Described radially stuck point is 4 that uniform ring is established.

The utility model with through hole the inner establish one with the retaining wall of end cap integrative-structure, going out axle bearing the inner is connected on the retaining wall end face, describedly go out the axle bearing outer face and fix by the wild card bit architecture that is located at the openings end, the some radially stuck points of wild card bit architecture for going out by openings end eaves wall riveting, make out that axle bearing can axial motion, guaranteed rotor stable operation, and go out that axle bearing is installed by the outer end and by the riveting solid line, simple in structure, easy for installation.

Description of drawings

The utility model will be further described below in conjunction with accompanying drawing:

Fig. 1 is the schematic diagram of the mounting structure of existing Motor Shaft bearing;

Fig. 2 is the schematic diagram of the improved mounting structure of the utility model Motor Shaft bearing and end cap;

Fig. 3 is an axial view of the present utility model.

Embodiment

As shown in Figures 2 and 3, improved mounting structure for a kind of Motor Shaft bearing of the utility model and end cap, comprise axle bearing 2 and be provided with the end cap 1 that leads to 11 holes, described through hole the inner is provided with the retaining wall 12 with the end cap integrative-structure, describedly go out axle bearing 2 the inners and be connected on retaining wall 13 end faces, describedly go out the axle bearing outer face and fix by the wild card bit architecture that is located at 11 mouthfuls of ends of through hole, the some radially stuck points 14 of described wild card bit architecture for going out by openings end eaves wall riveting, described in the utility model radially stuck point be 4 that uniform ring is established.

Claims
