Description
Technical field
The utility model relates to a kind of automobile component, is specifically related to a kind of radiator fans.
Background technology
In the process of moving, engine can produce too much heat to vehicle, and in order to allow engine can not because of overheated and cisco unity malfunction, people devise liquid circulation cooling system, and wherein radiator fan plays a part very important.The ordinary construction of existing radiator fans is: comprise fan electromotor, fan electromotor comprises electric machine casing and front and rear cover, front end housing is provided with through hole and stretches out outward by fan electromotor axle, electric machine casing and front end housing are normally by stretching mode global formation, complex process, assembling is also inconvenient, and particularly brush holder can be cumbersome when assembling; And the fore bearing chamber formed on front end housing by the way can only be protrude to away from motor internal direction, motor shaft front support is built-in, so the axial location of motor shaft needs to carry out strict guarantee by the size between each part in assembling process, add assembly difficulty.Or, electric machine casing and front end housing adopt Split type structure, the connected mode of electric machine casing and front end housing is: the inwall of electric machine casing is riveted or is welded and fixed many installation feet, thread mill drilling on installation foot, electric motor end cap is provided with screw hole, and bolts through bolt holes rear thread is screwed on installation foot, and shortcoming is that project organization is more complicated, motor internal narrow space, is unfavorable for assembling.
Summary of the invention
In view of the deficiencies in the prior art, the utility model provides a kind of technique simple and convenient assembly type radiator fans simple, easy to assembly.
The utility model takes following technical scheme:
Simple and convenient assembly type radiator fans, comprise fan electromotor, fan electromotor comprises electric machine casing and front and rear cover, front end housing is provided with through hole and stretches out outward by fan electromotor axle, it is characterized in that: electric machine casing, front end housing and rear end cap adopt Split type structure, front end housing is provided with fore bearing chamber, fore bearing chamber is recessed to motor internal direction, by cover plate block after the mounted motor axle front support of fore bearing chamber, rear end cap is provided with rear bearing chamber, rear bearing chamber is protruded to away from motor internal direction, rear bearing chamber mounted motor axle rear support; Described front end housing is connected by special-shaped screw and nut with between electric machine casing, the head of screw of special-shaped screw and screw rod are mutually an angle of 90 degrees bending, described front end housing is provided with screw hole, the sidewall of described electric machine casing cylindrical is provided with elongated hole, and the screw rod of special-shaped screw being horizontally through elongated hole, spinning with described nut longitudinally through passing outward after screw hole from electric machine casing cylindrical sidewall.
Adopt after technique scheme, the Advantageous Effects that the utility model realizes is: 1. electric machine casing, front end housing adopt Split type structure, and technique is simple, easy to make, is beneficial to the assembling of motor internal part particularly brush holder, makes easy to assembly; 2. because fore bearing chamber is recessed to motor internal direction, so fore bearing chamber and motor shaft front support just can be placed on electric machine casing, such motor shaft front support just can be assembled outside motor, as long as at this moment simply arrange on motor shaft and carry out spacing back-up ring to front support, just easily can realize the reliable axial location of motor shaft, make easy to assembly; 3. installation foot need be set at electric machine casing inwall and can realize being fixedly connected with of electric machine casing and front end housing, project organization is simple, increase motor internal space, be beneficial to assembling and installation and maintenance.
