Abstract
The utility model relates to a motor bearing seal structure which contains a clamping ring used for fixing a rotor punching plate and a rotary shaft labyrinth seal provided with bearings, wherein the labyrinth seal is arranged along the radial direction of a rotary shaft between an end cap and the clamping ring. As the labyrinth seal groove is radially configured changing from original axial configuration, axial size of a motor is shortened such that the structure of the motor is compact. Safe and reliable operation of the motor is guaranteed.
Description
Technical field
The utility model relates to a kind of motor bearings hermetically-sealed construction.
Background technology
The bearing seal of motor output end adopts labyrinth sealing mostly, it comprises end cap, for the trim ring of fixed rotor punching with the rotating shaft of bearing is installed, labyrinth sealing is located between axle sleeve and end cap, because labyrinth sealed maze trough length is larger, thereby cause the sealed electric-motor axial length of this structure larger.
Utility model content
In order to overcome above defect, the purpose of this utility model is to provide a kind of compact conformation, shortens a kind of motor bearings hermetically-sealed construction of motor axial length.
The technical solution of the utility model is: a kind of motor bearings hermetically-sealed construction, and it comprises for the trim ring of fixed rotor punching, the rotating shaft labyrinth sealing of bearing is installed, and described labyrinth sealing is radially located between end cap and trim ring along rotating shaft.
In order to be beneficial to the dismounting of bearing, the inner side of described bearing is provided with axle sleeve, and described axle sleeve is provided with technique kerve.
Technique effect of the present utility model is, due to by labyrinth sealing groove by the original radial arrangement that axially makes into, thereby dwindle the axial dimension of motor, make electric machine structure compact.Guarantee motor safety reliability service.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A place partial enlarged drawing of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
With reference to accompanying drawing, a kind of motor bearings hermetically-sealed construction, it comprises trim ring 1, end cap 2, bearing 3, axle sleeve 4, rotating shaft 5.Described trim ring 1 is for fixed rotor punching 6, and described bearing 3 is placed in rotating shaft 5, and side is provided with axle sleeve 4 within it.Described axle sleeve 4 is provided with technique kerve 7, and during dismounting, frock drag hook hooks technique kerve 7, and related bearing 3 inner rings are together dismantled.Between end cap 2 and trim ring 1, along rotating shaft 5, be radially provided with labyrinth seal structure 8, during work, being located at staggers to coordinate between tongue and groove I 8-1 on the trim ring 1 of rotation and the tongue and groove II 8-2 being located on fixing end cap 2 mutually forms labyrinth seal structure 8, make the road long enough of the sealing of grease in labyrinth seal structure 8, reach the effect of seal grease.
Due to by labyrinth sealing groove by the original radial arrangement that axially makes into, thereby the axial dimension of the motor dwindling makes electric machine structure compact.Guarantee motor safety reliability service.
Be more than a kind of execution mode of the present utility model, a preferred demonstration example.The scope that the utility model application is asked for protection has more than and is limited to described execution mode.All and technical scheme the present embodiment equivalence all belongs to protection range of the present utility model.
Claims (2)
