Abstract
The utility model relates to a reinforced belt tightening pulley, and belongs to the technical field of mechanical transmission. The reinforced belt tightening pulley comprises a belt pulley and a supporting plate connected with the belt pulley; a spring supporting sleeve is arranged on the supporting plate; a spring in which a spring base plate is arranged is arranged in the spring supporting sleeve; a base plate is arranged between the spring and the supporting plate; a panel is arranged on the end surface of the supporting plate; a wearing plate is arranged between the panel and the spring supporting sleeve; a reinforcing component is fixedly connected to a part, tangent to the spring supporting sleeve, of the supporting plate, and is integrated with the part; a collar is arranged on a central shaft of the spring supporting sleeve; a bearing is arranged in a concave groove formed by the belt pulley and the supporting plate; a dust proofing cover is fixed on the end surface of the belt pulley by virtue of shaft bolts; and an included angle between an external tangent surface and a jointing surface of the reinforcing component ranges from 45 degrees to 60 degrees.
Description
Technical field
The utility model relates to a kind of reinforced tension pulley, 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.Prior art, Idle wheel in running when belt fracture or other part failure, make the Idle wheel support plate get back to free position from maximum travel position, moment is unclamped the sizable power that produces, make support plate and free position spring supporting cover biting point produce bump, because the occlusal surface insufficient strength of Idle wheel is large, interlock place of support plate or spring supporting cover is interrupted, cause product failure or get to other part of motor, cause great accident.
The model utility content
Technical problem to be solved in the utility model provides the tension pulley that a kind of support plate is strengthened.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Reinforced tension pulley, comprise belt pulley and the support plate that is connected belt pulley, described support plate is provided with the spring supporting cover, be provided with spring in the described spring supporting cover, be provided with the spring backing plate in the spring, be provided with backing plate between described spring and the support plate, described support plate end face is provided with panel, panel and spring supporting inner room are provided with wearing plate, and described support plate and spring supporting overlap the reinforcer that is connected with on the tangent part with its one.
Described spring supporting cover central shaft is provided with lasso.
Be provided with bearing in the groove that described belt pulley and support plate form, and the belt pulley end face is fixed with dust cover by axle bolt.
Outer tangent plane and occlusal angle as preferred described reinforcer are in 45 ° to the 60 ° scopes.
According to the technical solution of the utility model, the support plate of tension pulley and spring supporting overlap the reinforcer that is connected with on the tangent part with its one, strengthen occlusal stressed support.The outer tangent plane of reinforcer and occlusal angle are in 45 ° to the 60 ° scopes, so that support plate is got back to the moment maximum of free position from maximum travel position.
