The utility model discloses well wave washer gives ball bearing outer lane a suitable precompression to reduce antifriction bearing's play, reduce the bearing vibration noise that produces from this.
Description
The technical field is as follows:
the utility model relates to a ball bearing pretightning force device.
Background art:
the blower motor of the present automobile air conditioning system is mainly divided into two structure motors of an oil bearing and a ball bearing, and the motor of the ball bearing structure has the advantages of simple assembly process, long service life, good product consistency and the like. However, due to the structure of the ball bearing, the ball bearing has a certain clearance, and when the motor operates, certain noise is generated, so that the comfort of a driver is affected.
The utility model has the following contents:
the utility model relates to a solve the problem that above-mentioned prior art exists and provide a ball bearing pretightning force device.
The utility model discloses the technical scheme who adopts has: the utility model provides a ball bearing pretightning force device, includes front end housing, brush board assembly, ball bearing, rotor assembly and stator assembly, ball bearing is installed respectively at the both ends of rotor assembly, and ball bearing installs in the bearing room of stator assembly, and brush board assembly installs on stator assembly, and the front end housing is installed on stator assembly, still includes the wave form packing ring, is equipped with the wave form packing ring in every ball bearing's the outside.
Further, the parameters of the wave washer are as follows: the total height h of the wave-shaped curve is 1.8-2.5 mm, the phi x of the inner ring is 13-15 mm, the phi y of the outer ring is 20-21.8 mm, and the thickness of the wave-shaped spring is 0.3-0.6 mm.
The utility model discloses following beneficial effect has:
the utility model discloses well wave washer gives ball bearing outer lane a suitable precompression to reduce antifriction bearing's play, reduce the bearing vibration noise that produces from this.
Description of the drawings:
fig. 1 is a schematic structural diagram of the motor of the present invention.
Fig. 2 is a schematic view of the wave washer of the present invention.
Fig. 3 is a schematic view of the structure of the bearing chamber of the present invention.
The specific implementation mode is as follows:
the present invention will be further described with reference to the accompanying drawings.
As fig. 1 to fig. 3, the utility model relates to a ball bearing pretightning force device, including front end housing 1, brush board assembly 2, ball bearing 3, rotor assembly 4, wave washer 5 and stator assembly 6, ball bearing 3 is installed respectively at the both ends of rotor assembly 4, and ball bearing 3 installs in the bearing room of stator assembly 6, and brush board assembly 2 installs on stator assembly 6, and front end housing 1 installs on stator assembly 6, is equipped with wave washer 5 in every ball bearing 3's the outside.
The parameters of the wave washer 5 are: the total height h of the wave-shaped curve is 1.8-2.5 mm, the phi x of the inner ring is 13-15 mm, the phi y of the outer ring is 20-21.8 mm, and the thickness of the wave-shaped spring is 0.3-0.6 mm.
The utility model discloses well wave washer 5 gives 3 outer lane of ball bearing a suitable precompression to reduce antifriction bearing 3's play, reduce the bearing vibration noise that produces from this.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications can be made without departing from the principle of the present invention, and these modifications should also be regarded as the protection scope of the present invention.
