Abstract
The utility model relates to the technical field of belt pulleys, and particularly relates to a unidirectional belt pulley which comprises a pulley body, a spindle, an entity bushed needle roller bearing and a deep groove ball bearing, wherein the pulley body is connected with the spindle; and the deep groove ball bearing and the entity bushed needle roller bearing are arranged between the pulley body and the spindle. According to the unidirectional belt pulley, a radial fit clearance between the bearings is enlarged, the radial run-out generated during the rotation process of the belt pulley is reduced, the work reliability of the belt pulley is ensured, noises generated during the high-speed rotation process is reduced, the rated load of the belt pulley is improved, the service life of the belt pulley is prolonged, and the unidirectional belt pulley is easy to use and promote.
Description
Technical field
The utility model relates to a kind of technical field of belt pulley, especially a kind of one-way belt sheave.
Background technique
Existing one-way belt sheave mounted inside one cover drawn cup needle roller overrunning clutch; The difficult in process of production concentricity requirement of drawn cup and roughness, the form and position tolerance of outer ring raceway controlled; Cause one-way belt sheave in high speed rotating radially beat bigger; Be difficult to effectively protect generator, the conference of circular runout simultaneously causes the power loss of motor, and drawn cup needle roller overrunning clutch assembling play is bigger; Make belt pulley further strengthen its radial beat eccentricity when rotated, shortened the working life of belt pulley.
The model utility content
Circular runout causes generator power loss short deficiency in big and working life greatly when overcoming existing one-way belt sheave high speed rotating, and the utility model provides a kind of one-way belt sheave.
The utility model solves the technological scheme that its technical problem adopted: a kind of one-way belt sheave; Comprise wheel body, mandrel, deep groove ball bearing and entity lasso needle bearing; Wheel body is connected with mandrel, is provided with deep groove ball bearing and entity lasso needle bearing between wheel body and the mandrel.
According to another embodiment of the utility model, comprise that further the mandrel outside is provided with back-up ring.
According to another embodiment of the utility model, further comprise between wheel body and deep groove ball bearing and the entity lasso needle bearing being provided with drawn cup needle roller clutch.
The beneficial effect of the utility model is; This one-way belt sheave has improved the radial fit play between bearing, has reduced the circular runout that produces when belt pulley rotates, and has guaranteed the reliability of belt pulley work; And the noise that has produced when having reduced high speed rotating; Improved the load rating of belt pulley, prolonged the working life of belt pulley simultaneously, be easy to use and promote.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
1. wheel bodys among the figure, 2. mandrel, 3. deep groove ball bearing, 4. entity lasso needle bearing, 5. back-up ring, 6. drawn cup needle roller clutch.
Embodiment
Like Fig. 1 is the structural representation of the utility model; A kind of one-way belt sheave; Comprise wheel body 1, mandrel 2, deep groove ball bearing 3 and entity lasso needle bearing 4, wheel body 1 is connected with mandrel 2, is provided with deep groove ball bearing 3 and entity lasso needle bearing 4 between wheel body 1 and the mandrel 2; Mandrel 2 outsides are provided with back-up ring 5, are provided with drawn cup needle roller clutch 6 between wheel body 1 and deep groove ball bearing 3 and the entity lasso needle bearing 4.
During use; Deep groove ball bearing 3, entity lasso needle bearing 4 and back-up ring 5 are enclosed within the outside of mandrel 2; Wheel body 1 is enclosed within deep groove ball bearing 3 and entity lasso needle bearing 4 outsides, and the internal surface of wheel body 1 inner ring is connected with mandrel 2, and deep groove ball bearing 3 is connected with the endoporus of wheel body 1 with entity lasso needle bearing 4 outer ring outer surfaces; Supporting in the wheel body 1 with bearing one end adopts deep groove ball bearing 3 to improve the radial fit play; The other end adopts entity lasso needle bearing 4 to improve the load ratings of belt pulley, and bearing that belt pulley is joined adopts split design, drawn cup overrunning clutch 6 with joining bearing separate assembling; Drawn cup overrunning clutch 6 plays locking and surmounts effect, and deep groove ball bearing 3 plays the radial support effect with entity lasso needle bearing 4.This one-way belt sheave has improved the radial fit play between bearing; The circular runout that has produced when having reduced the belt pulley rotation; Guarantee the reliability of belt pulley work, and the noise that produces when having reduced high speed rotating, improved the load rating of belt pulley; Prolonged the working life of belt pulley simultaneously, be easy to use and promote.
