Description
Technical field
This utility model relates to engine apparatus technical field, especially relates to a kind of automobile tension wheel flange.
Background technology
Expansion tightening wheel is the belt stretcher for car transmissions, the effect of expansion tightening wheel is used to regulate the elasticity of Timing Belt, after having had expansion tightening wheel belt, automobilism is more steady, and noise reduces, it is prevented that automobile skids, the spring of existing expansion tightening wheel is located in cannelure, such spring easily gets loose, and causes that expansion tightening wheel loses its function, affects automobile normal running.
Utility model content
The technical problems to be solved in the utility model is: the spring in order to solve expansion tightening wheel is located in the problem easily got loose in cannelure, now provides a kind of automobile tension wheel flange.
This utility model solves its technical problem and be the technical scheme is that a kind of automobile tension wheel flange, including flange body and spring, one end of described flange body offers the annular housing matched with described spring outer diameter, the described flange body other end offers the first through hole, described first through hole and described flange body coaxial line, described first through hole inner peripheral surface is provided with projection, the cannelure matched with described spring string diameter is offered bottom described annular housing, one end of described spring is fastened in cannelure, described cannelure two sides are provided with projection, described spring offers the groove matched with described projection, described groove is slidably arranged in projection, described flange body is removably connected with fixing plate, described fixing plate is provided with the boss matched with described cannelure, described boss is slidably arranged in described cannelure, described boss offers the second through hole matched with described spring, one end of described spring is located in the second through hole, the groove of spring is slidably arranged in the projection in cannelure, limit spring movement in cannelure, one end of spring is located in the second through hole of boss, limit spring to move axially along flange body, spring is better prevented to slip projection.
In order to better prevent spring from slipping out from projection, further, described fixing plate is positioned at above projection, projection limits spring movement in cannelure on the one hand, on the other hand fixing plate limits spring along the axial movement of flange body, owing to fixing plate is above mentioning, protruding and fixing plate better limits spring, better prevents ejection to slip from projection.
Flange body is by casting, original projection has four along the first through hole inner peripheral surface distribution, projection itself is relatively larger, in projection, shrinkage cavity easily occurs when casting, cause that the intensity of projection is substantially reduced, further, described projection has eight and is uniformly distributed along described first through hole inner peripheral surface, owing to projection is evenly distributed with eight along the first through hole inner peripheral surface, neither affect the intensity that projection is overall, well solve again the problem of shrinkage cavity on projection.
The beneficial effects of the utility model are: this utility model automobile tension wheel flange, the groove of spring is slidably arranged in the projection in cannelure on the one hand, both match the movement well limiting spring in cannelure, spring is located in the second through hole of boss on the other hand, both match and well limit spring and move axially along flange body, by the these two aspects restriction to spring, spring is better prevented to slip projection, projection is evenly distributed with eight along the first through hole inner peripheral surface simultaneously, neither affect the intensity that projection is overall, well solve again the problem of shrinkage cavity on projection, this utility model has simple in construction, easy to operate, spring fixation is reliable, also ensure that the intensity that flange is good simultaneously.

Detailed description of the invention
Presently in connection with accompanying drawing, the utility model is described in more detail.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the composition relevant with this utility model.
Embodiment 1
As shown in Figure 1,2 and 3, a kind of automobile tension wheel flange, including flange body 1 and spring 2, one end of described flange body 1 offers the annular housing 8 matched with described spring 2 external diameter, described flange body 1 other end offers the first through hole 7, described first through hole 7 and described flange body 1 coaxial line, described first through hole 7 inner peripheral surface is provided with projection 10；
As shown in Figure 1, described projection 10 has eight and is uniformly distributed along described first through hole 7 inner peripheral surface, the cannelure 3 matched with described spring 2 string diameter is offered bottom described annular housing 8, described spring 2 one end is fastened in cannelure 3, described cannelure 3 two sides are provided with protruding 4, offering on described spring 2 and described protruding 4 grooves 5 matched, described groove 5 is slidably arranged on protruding 4；
Such as Fig. 1, shown in 4 and 5, described flange body 1 is removably connected with fixing plate 6, fixing plate 6 is connected with flange body 1 by screw, described fixing plate 6 is positioned at above in the of protruding 4, described fixing plate 6 is provided with the boss 11 matched with described cannelure 3, described boss 11 is slidably arranged in described cannelure 3, and described boss 11 offers the second through hole 9 matched with described spring 2, and one end of described spring 2 is located in the second through hole 9.
