Abstract
The utility model discloses fan motor front motor end caps, including being formed by end cap cover board by steel plate punched stretching, the central location design of end cap cover board has interior hole flanging structure, and interior hole flanging crosses first bearing room cavity, rear bearing is pressed in the cavity of first bearing room, it is characterised in that：The front of end cap cover board is equipped with minor flaps, minor flaps are fixedly linked with end cap cover board, and the central location design of minor flaps has preceding hole flanging structure, and preceding hole flanging crosses second bearing room cavity, fore bearing is pressed in the cavity of second bearing room, forward and backward bearing is coaxially disposed and leaves each other set distance.The utility model can realize that rotor axis of electric in the intracorporal single head bearing of motor casing, simplifies fan motor structure.
Description
Technical field
The utility model relates to a kind of radiator fans for car engine cooling system, and in particular to a kind of fan
The front motor end cap of motor.
Background technique
Cooling device for automobile engine with water it is cooling based on, with the circulating water in cylinder water channel, heated in water channel
Water introduce radiator, by being again returned in water channel after air cooling.In order to improve the cooling capacity of radiator, need radiating
Radiator fan forced ventilation is installed behind device.The critical component of radiator fan is fan motor, in the prior art, fan electricity
The armature spindle of machine required in electric machine casing carry out both ends bearing, front bearing by be set to front motor end cap in fore bearing Lai
It completes, back bearing is completed by the rear bearing being set in rear electric motor end cap, and structure is relative complex, unsuitable some special vehicles
Type use occasion.
Summary of the invention
In view of the deficiencies in the prior art, it is intracorporal in motor casing that the utility model provides a kind of achievable rotor axis of electric
Single head bearing, simplifies the fan motor front motor end cap of fan motor structure.
The utility model adopts the following technical scheme that complete：
Fan motor front motor end cap, including end cap cover board, the center of end cap cover board are formed by by steel plate punched stretching
Position Design has interior hole flanging structure, and interior hole flanging crosses first bearing room cavity, is pressed with rear bearing in the cavity of first bearing room,
It is characterized in that：The front of end cap cover board is equipped with minor flaps, and minor flaps are fixedly linked with end cap cover board, and the central location of minor flaps is set
In respect of preceding hole flanging structure, preceding hole flanging crosses second bearing room cavity, is pressed with fore bearing, axle in the cavity of second bearing room
It holds and is coaxially disposed and leaves each other set distance.
It is provided with collapsible dist collar between forward and backward bearing and be separated by separating by collapsible dist collar.
The minor flaps spot-welded is on end cap cover board.
After adopting the above technical scheme, front motor end cap increases on the basis of only end cap cover board originally is provided with tegillum
Plate, and second bearing room cavity is provided in minor flaps, the first bearing room cavity that cooperation end cap cover board is equipped with is then preceding electric
With regard to mountable front and back bearings and front and back bearings leave each other set distance in generator terminal lid, so, rotor axis of electric is preceding
Electric motor end cap just has been able to obtain more reliable radial support without coming again in rear electric motor end cap setting bearing to it
It is supported, simplifies electric machine structure, to adapt to special vehicle use occasion.In addition, between forward and backward bearing in front motor end cap
Be separated by separating by collapsible dist collar, the axial vibration of rotor axis of electric can be reduced, improves fan motor service life.
Detailed description of the invention
The utility model has following attached drawing：
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
As shown, the fan motor front motor end cap of the utility model, including end is formed by by steel plate punched stretching
The central location design of lid cover board 3, end cap cover board 3 has interior hole flanging structure, and interior hole flanging crosses first bearing room cavity 2, first axle
It holds and is pressed with rear bearing 1 in room cavity 2, the front of end cap cover board 3 is equipped with minor flaps 5, and 5 spot-welded of minor flaps is in end cap cover board
On 3, the central location design of minor flaps 5 has preceding hole flanging structure, and preceding hole flanging crosses second bearing room cavity 6, and second bearing room is empty
Fore bearing 7 is pressed in chamber 6, fore bearing 1, rear bearing 7 are coaxially disposed and leave each other set distance, fore bearing 1, rear bearing 7
Between be provided with collapsible dist collar 4 and be separated by separating by collapsible dist collar 4, collapsible dist collar 4 is made of hard rubber material.
