Abstract
The utility model relates to a clutch bearing of an automobile silicone oil fan, which comprises an inner ring, an outer ring, a retainer, steel balls and a sealing ring, wherein the inner and the outer rings are double channels, and the steel balls are uniformly distributed between the inner and the outer rings via the retainer. The clutch bearing is characterized in that the side ends of a fixed bearing are separated by adopting the sealing ring made by heat-resistant polyacrylate material and an oil seal. The utility model can effectively prevent silicone oil from entering a bearing cavity and improve the service life of the bearing.
Description
Technical field
The utility model relates to bearing, particularly be a kind of silicone oil fan clutch bearing in automobile.
Background technique
Silicon oil clutch is a medium with silicone oil, utilizes its high viscosity characteristic transmitting torque.When engine temperature was low, the silicone oil viscosity was higher, and fan clutch separates, and rotation speed of the fan slows down; When engine temperature was higher, the silicone oil viscosity was low, the fan clutch combination, and fan and water pump are worked together, play the effect of regulating engine temperature.
Compare with common fan clutch, silicon oil filled fan clutch can be regulated rotation speed of the fan automatically, and motor is worked under optimum working temperature, has advantages such as fuel-economizing, noise reduction, reduction of discharging.During engine cold-start, often require fan to rotate, but rotating speed can not be too fast, conventional fan does not satisfy, and silicon extraction fan clutch utilizes the viscosity property of silicone oil to satisfy.This advantage that embodies on commercial car is more obvious, and the discharge capacity of commercial vehicle engine is bigger, how more than 10 liters, the power that fan consumed accounts for about 6% of total output, use silicon oil filled fan clutch, can reduce fuel consume 2%～3%, the effect that reduces oil consumption is very obvious.In addition, the fan dimension of commercial vehicle engine is bigger, and the noise of generation is often also bigger, and the advantage of silicon oil filled fan clutch aspect noise reduction is also very outstanding.The development of silicon oil filled fan clutch will bring the wide market as the bearing of critical component.
The model utility content
In order to overcome above-mentioned defective, the purpose of this utility model provides a kind of silicone oil fan clutch bearing in automobile.
The utility model adopts following technological scheme:
Silicone oil fan clutch bearing in automobile, it comprises inner ring, outer ring, retainer, steel ball, seal ring, Internal and external cycle is a double channel, steel ball is evenly distributed between inner ring and the outer ring by retainer, it is characterized in that: adopt the seal ring of fire resistant polypropylene acid fat material and the side that oil sealing separates rigid bearing.
The utility model effectively stops silicone oil to enter bearing bore, improves bearing life.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Specific embodiments
Further specify with reference to the accompanying drawings.
As shown in Figure 1, silicone oil fan clutch bearing in automobile, it comprises inner ring 2, outer ring 1, retainer 3, steel ball 4, seal ring 5, oil sealing 6, steel ball 4 is evenly distributed between inner ring 2 and the outer ring 1 by retainer 3, it is characterized in that: adopt the seal ring 5 of fire resistant polypropylene acid fat material and the side that oil sealing 6 separates rigid bearing.
At last, should be pointed out that above embodiment only is the more representational example of the utility model.Obviously, the technical solution of the utility model is not limited to the foregoing description, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
