The belt tightening pulley with the butterfly spring comprises a belt pulley and a supporting plate connected with the belt pulley; a spring supporting sleeve and a central shaft sleeve are arranged on the supporting plate; a spring in which a spring base plate is arranged is arranged in the spring supporting sleeve; a gasket is arranged between the spring supporting sleeve and the supporting plate; an end cover is arranged on the end surface of the supporting plate; the end cover, the spring supporting sleeve and the central shaft sleeve are concentric; a dust proofing plug is arranged on the end cover; a butterfly spring seat is arranged in a concave groove formed between the end cover and the supporting plate; the butterfly spring is arranged in the butterfly spring seat; a bushing block is arranged on the central shaft sleeve; a bearing is arranged in the belt pulley; an elastic check ring is arranged between the belt pulley and the supporting plate; and a dust proofing cover is fixed on the end surface of the belt pulley by virtue of a hexagon-headed shouldered bolt.
Description
Technical field
The utility model relates to a kind of tension pulley with butterfly spring, belongs to the mechanical transmission field of accessories.
Background technique
In vehicle transmission, belt transmission is used very extensive, and is effective in order to guarantee reliable transmission, tension pulley is installed is necessary very much.Idle wheel is installed on the motor car engine, mainly plays a part automatically to regulate the driving belt tightness, and when driving belt loaded, Idle wheel reduced driving belt along the displacement of loading direction to reverse resistance of loading direction; Let out when carrying when driving belt, Idle wheel lets out the push-tight power of carrying direction for rapidly one of driving belt, guarantees that driving belt is in rational state all the time.For the efficient that makes Idle wheel reaches maximum, should guarantee that the moving direction of support plate is parallel with belt all the time.
The model utility content
Technical problem to be solved in the utility model provides all the time the tension pulley with butterfly spring parallel with belt direction of travel of a kind of support plate direction.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Tension pulley with butterfly spring, comprise belt pulley and the support plate that is connected belt pulley, described support plate is provided with spring supporting cover and central axle sleeve, be provided with spring in the described spring supporting cover, be provided with the spring backing plate in the described spring, be provided with packing ring between described spring supporting cover and support plate, described support plate end face is provided with end cap, and end cap and spring supporting cover, central axle sleeve three concentric, described end cap is provided with dustproof plug, and be provided with the butterfly spring seat in the groove that forms between end cap and support plate, be provided with butterfly spring in the described butterfly spring seat.
Described central axle sleeve is provided with lining.
Be provided with bearing in the described belt pulley, and be provided with circlip between belt pulley and support plate, described belt pulley end face is fixed with dust cover by the hexagon head shouldered tap bolt.
According to the technical solution of the utility model, with being provided with the butterfly spring seat in the groove that forms between the end cap of the tension pulley of butterfly spring and support plate, be provided with butterfly spring in the described butterfly spring abutment, adopt butterfly spring axial compression support plate, guarantee the parallelism of tension pulley support plate and belt, thereby so that the moving direction of support plate is parallel with belt all the time, increase Idle wheel to the functioning efficiency of belt.
