Abstract
The utility model discloses radiator fan electric motor end cap, comprise the end cap cover plate stretching formed by steel plate punched, it is characterized in that: the medium design of described end cap cover plate becomes interior hole flanging structure, and the centre of interior hole flanging press-fits a bearing pedestal, described bearing pedestal is also stretched by steel plate punched and formed.The technical problem that the utility model mainly solves is the bearing pedestal that can also form enough bearing bore degree of depth when electric motor end cap is height-limited on end cap, avoid end cap cover plate to be excessively stretched when shaping simultaneously, eliminate the generation that end cap cracking etc. has a strong impact on motor quality situation and phenomenon.
Description
Technical field
The utility model relates to a kind of radiator fan for car engine cooling system, is specifically related to a kind of electric motor end cap of radiator fan.
Background technology
Cooling device for automobile engine, based on water cooling, with the circulating water in cylinder water channel, introduces radiator, by turning back in water channel after air cooling the water be heated in water channel again.In order to improve the cooling capacity of radiator, need installation of heat radiator fan forced ventilation after radiator.The critical component of radiator fan is motor, the front and rear cover of usual motor is all pass through punching press by steel plate, the operation straight formings such as stretching and reach we require size, but some motors are restricted due to overall dimension, the front and rear cover of motor must be very compact, its requirement for height is just smaller, and the size constancy of motor bearings, this just needs to keep the depth dimensions of the bearing bore on end cap constant, in these cases, necessarily require end cap will do when shaping bearing bore significantly to stretch, end cap is caused to be excessively stretched when shaping, not only end cap cracking phenomena is general, have a strong impact on motor quality, and also harmful effect is caused to mould.
Summary of the invention
In view of the deficiencies in the prior art, the utility model provides a kind of bearing pedestal that can also form enough bearing bore degree of depth when end cap is height-limited on end cap, avoids the radiator fan electric motor end cap that end cap cover plate is excessively stretched when shaping simultaneously.
The utility model takes following technical scheme:
Radiator fan electric motor end cap, comprises the end cap cover plate stretching formed by steel plate punched, it is characterized in that: the medium design of described end cap cover plate becomes interior hole flanging structure, and the centre of interior hole flanging press-fits a bearing pedestal.
Described bearing pedestal is also stretched by steel plate punched and formed.
The bearing loading port of described bearing pedestal is provided with outer turned welt.
After adopting technique scheme, electric motor end cap assembles after being press-fited together with bearing pedestal by end cap cover plate shaping respectively, end cap cover plate only need go out interior hole flanging structure and is convenient to install by bearing pedestal by hole site punching stretch in middle, the hole flanging height of interior hole flanging can require to design according to differing heights, avoid end cap cover plate to be excessively stretched when shaping and cause the generation of end cap cracking phenomena, and the height of bearing pedestal self is just very easy to obtain controlling only need meet the bearing bore degree of depth.So by the enforcement of technique scheme, the utility model just solves the bearing pedestal that can also form enough bearing bore degree of depth when electric motor end cap is height-limited on end cap, avoid end cap cover plate to be excessively stretched when shaping simultaneously, eliminate the generation that end cap cracking etc. has a strong impact on motor quality situation and phenomenon.
accompanying drawing explanation
The utility model has following accompanying drawing:
Fig. 1 is the radiator fan electric machine structure figure with the utility model electric motor end cap;
Fig. 2 is the structural representation of the utility model electric motor end cap;
Fig. 3 is the structural representation of conventional motors end cap.
Embodiment
As illustrated in fig. 1 and 2, the front and back of radiator fan motor are provided with electric motor end cap, the supporting of bearing 3 for rotor axis of electric is installed in electric motor end cap, electric motor end cap comprises the end cap cover plate 1 and bearing pedestal 2 stretching formed by steel plate punched, end cap cover plate 1 and bearing pedestal 2 are individual part, the medium design of described end cap cover plate 1 becomes interior hole flanging 4 structure, the hole flanging height of interior hole flanging 4 can require to design according to differing heights, described bearing pedestal 2 is fitted in the centre of interior hole flanging 4, the height of bearing pedestal 2 only need meet the depth dimensions (the axial installation dimension of bearing 3) of bearing bore 6, the bearing loading port of described bearing pedestal 2 is provided with outer turned welt 5.
As shown in Figure 3, traditional radiator fan electric motor end cap, by single steel plate by the operation such as punching press, stretching straight forming, the position of its bearing bore 8 will reach the location status of Fig. 2, need steel plate significantly to stretch, its stretching position 7 is obviously very easy to occur cracking.
Claims (3)
1. radiator fan electric motor end cap, comprises the end cap cover plate stretching formed by steel plate punched, it is characterized in that: the medium design of described end cap cover plate becomes interior hole flanging structure, and the centre of interior hole flanging press-fits a bearing pedestal.
2. radiator fan electric motor end cap as claimed in claim 1, is characterized in that: described bearing pedestal is also stretched by steel plate punched and formed.
