Description
Technical field
The utility model is related to belt pulley technical field, specially new power-assisted steering pump belt pulley.
Background technology
During work, interior axle easily occurs splitting during stress traditional belt pulley with the junction of foreign steamer
Seam, and then shorten the service life of belt pulley；Meanwhile, traditional belt pulley, after opening up louvre, directly results in belt pulley
Structural strength reduce, and then reduce the service life of belt pulley.
Utility model content
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of big new of structural strength to help
Power steering pump pulley.
For achieving the above object, the utility model provides following technical scheme: new power-assisted steering pump belt pulley, including
Pulley body, described pulley body includes interconnective interior axle and foreign steamer, and described foreign steamer is set in interior axle, interior
The junction of axle and foreign steamer is provided with the transition cambered surface of ring-type, and described foreign steamer includes interconnective bracing ring and stress portion,
Support ring is provided with and is evenly equipped with ring tooth group；
Described stress portion is included by interconnective first connecting plate of loop and the second connecting plate；
On described foreign steamer, circular array shows several louvres, the first the first plane being sequentially connected of the empty inclusion of radiating,
First cambered surface, the second plane, the second cambered surface, the 3rd plane and the 3rd cambered surface；
Described ring tooth group be respectively provided on two sides with the first positioning ring groove and the second positioning ring groove.
Contrast the deficiencies in the prior art, the beneficial effect that the technical scheme that the utility model provides is brought: 1. described in
Foreign steamer is set in interior axle, and interior axle is integrally formed with foreign steamer, and the junction of interior axle and foreign steamer is provided with the transition cambered surface of ring-type, and then
Increased the surface stress of interior axle and foreign steamer junction, increased the structural strength of interior axle and foreign steamer junction, prevent interior axle with
The phenomenon that crack in the junction of foreign steamer occurs, and extends the service life of belt pulley.2. annular array on the foreign steamer described in
Have several louvres, radiating is empty include the first plane, the first cambered surface, the second plane, the second cambered surface that first place is sequentially connected, the
Three planes and the 3rd cambered surface, the first cambered surface is used for connecting the first plane and the second plane, and the second cambered surface is used for connecting the second plane
With the 3rd plane, the 3rd cambered surface is used for connecting the 3rd plane and the first plane, is designed by above, increased each plane junction
Surface stress, and then increased the structural strength of each plane junction, during effectively preventing from using, crack in louvre
Phenomenon occur, extend the service life of belt pulley.
Brief description
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the cross-sectional schematic of Fig. 1.
Specific embodiment
Reference picture 1- Fig. 2 is described further to the utility model.
New power-assisted steering pump belt pulley, including pulley body, described pulley body includes interconnective interior
Axle 1 and foreign steamer, described foreign steamer is set in interior axle 1, and the junction of interior axle 1 and foreign steamer is provided with the transition cambered surface 11 of ring-type, institute
The foreign steamer stated includes interconnective bracing ring 21 and stress portion 22, and bracing ring 21 is provided with and is evenly equipped with ring tooth group 211；
Described foreign steamer is set in interior axle 1, and interior axle 1 and foreign steamer are integrally formed, and interior axle 1 is provided with ring with the junction of foreign steamer
The transition cambered surface 11 of shape, and then increased the surface stress of interior axle 1 and foreign steamer junction, increased interior axle 1 and foreign steamer junction
Structural strength, prevent the phenomenon that crack in the junction of interior axle 1 and foreign steamer from occurring, extend the service life of belt pulley.
Described stress portion 22 is included by interconnective first connecting plate 222 of loop 221 and the second connecting plate
223, by the design of loop 221, it is the effect that bracing ring 21 provides buffering；
On described foreign steamer, circular array shows several louvres 23, and radiating is empty to include the first plane that first place is sequentially connected
31st, the first cambered surface 32, the second plane 33, the second cambered surface 34, the 3rd plane 35 and the 3rd cambered surface 36, the first cambered surface 32 is used for connecting
First plane 31 and the second plane 33, the second cambered surface 34 is used for connecting the second plane 33 and the 3rd plane 35, and the 3rd cambered surface 36 is used
In connecting the 3rd plane 35 and the first plane 31, designed by above, increased each plane junction surface stress, and then increase
The structural strength of each plane junction, during effectively preventing from using, the phenomenon that crack in louvre 23 occurs, and extends
The service life of belt pulley；
Described ring tooth group 211 be respectively provided on two sides with the first positioning ring groove 01 and the second positioning ring groove 02, effectively position
Belt, improves efficiency of assembling.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, the skill of this area
Art personnel carry out common variations and alternatives in the range of technical solutions of the utility model and should be included in guarantor of the present utility model
In the range of shield.
