Abstract
The utility model relates to a free type belt pulley adopting an axial positioning structure. An inner hole of the belt pulley is used for installing a core shaft, a bearing is installed between the core shaft and the belt pulley, and the edge of the inner hole of the belt pulley is provided with a ring slot capable of carrying out vertical extrusion after the bearing is assembled. After the bearing is installed, the free type belt pulley extrudes the ring slot at the edge of the inner hole of the belt pulley by utilizing a mould, the slot edge of the extruded ring slot is deformed towards the middle of the inner hole and then is blocked at the outer side of the bearing so that the bearing installed in the inner hole is axially positioned, thereby preventing the bearing from axially loosening.
Description
Technical field
The utility model relates to a kind of belt pulley, especially a kind of Freestyle belt sheave that adopts axial positioning structure.
Background technique
Belt pulley belongs to dish hub class part, and generally based on casting, forging, material generally all is a cast iron on the manufacturing process.Belt pulley is mainly used in the occasion of remote transmission power, for example output of miniature diesel mechanomotive force, agricultural vehicle, tractor, automobile, mining machinery, machining equipment or the like.Belt pulley in use, the endoporus of belt pulley is equipped with mandrel, between mandrel and the belt pulley bearing is installed, but bearing is prone to axial play in axial not location, influences operation stability of equipment.
The model utility content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of Freestyle belt sheave that adopts axial positioning structure is provided, make the bearing that is installed on the belt pulley in axially locating, be difficult for producing axial play.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of Freestyle belt sheave that adopts axial positioning structure, the belt pulley endoporus is used to install mandrel, be used to install bearing between mandrel and the belt pulley, the interior bore edges of described belt pulley has the annular groove that can vertically push behind the running in bearings.
Further, described annular groove is opened in belt pulley endoporus both sides of the edge, but the equal axially locating of the bearing that the endoporus both sides are installed, and the belt pulley two ends are with the bearing axially locating.
The beneficial effects of the utility model are: the utility model is after installing bearing, utilize mould that the annular groove of bore edges in the belt pulley is pushed, the trough rim of annular groove after pushing to the endoporus intermediate deformation, the trough rim shelves are in the bearing outside, and then, prevent the bearing axial play with built-in bearing axially locating.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the enlarged diagram at A place among Fig. 1;
Fig. 3 is the structural representation after annular groove is extruded among Fig. 2;
Wherein: 1. belt pulley, 2. mandrel, 3. bearing, 4. annular groove.
Embodiment
A kind of Freestyle belt sheave that adopt axial positioning structure shown in Figure 2 as Fig. 1, belt pulley 1 endoporus is equipped with mandrel 2, between mandrel 2 and the belt pulley 1 deep groove ball bearing 3 is installed, the endoporus both sides of the edge of belt pulley 1 have the annular groove 4 that can vertically push behind the running in bearings 3.
As shown in Figure 3, after installing bearing 3, utilize mould that the annular groove 4 of bore edges in the belt pulley 1 is pushed, the trough rim of annular groove 4 after pushing to the endoporus intermediate deformation, the trough rim shelves are in bearing 3 outsides, and then, prevent bearing 3 axial play with built-in bearing 3 axially locating, realize the circumference axially locating of belt pulley 1 two ends to bearing 3.
Claims (2)
