Description

A kind of ball bearing of usheing to seat facilitating installation
Technical field
The present invention relates to a kind of bearing, especially a kind of ball bearing usherd to seat.
Background technique
Rolling bearing units are a kind of units for combining bearing and bearing block.In order to extend the service life of bearing, It needs often to refuel to bearing.Since bearing is arranged in bearing block, oiling mode is just provided with certainly rolling bearing units Oneself specific characteristic.Oil nozzle and oilhole are set usually on bearing block, oilhole then is set in the corresponding position of bearing outer ring, So then oil flows into Bearing inner, lubrication bearing component through the oilhole from oil nozzle by the oilhole of oilhole instillation bearing outer ring.
This oiling mode requires that the oilhole of bearing block is corresponding with the oilhole holding position of bearing outer ring consistent and opposite It is constant.But in actual operation, due to the rotation influence of axis opposite turn occurs for bearing outer ring between inevitable meeting and bearing block It is dynamic, thus it is difficult to ensure that between bearing block oilhole and bearing outer ring oilhole position consistency.
In addition, the sealing ring of ball bearing generally includes skeleton and rubber ring, needs first to be bonded between the two, be then fitted into In the seal groove of bearing, such installation steps are also comparatively laborious.
Summary of the invention
The present invention addresses the above problem, and providing one kind can be reduced opposite turn of generation between bearing outer ring and bearing block Ball bearing of usheing to seat that is dynamic, while facilitating sealing ring to install.To solve these problems, the invention adopts the following technical scheme:
A kind of ball bearing of usheing to seat facilitating installation, including ball bearing and bearing block, the bearing block are equipped with oil nozzle and oilhole, The corresponding position of the outer ring of the bearing is equipped with oilhole, which is characterized in that the lateral wall of the outer ring is equipped with seal groove, described close It is equipped with sealing framework in sealing groove, the outside of the sealing framework is equipped with rubber ring, the lateral wall of the rubber ring and bearing block Inner sidewall pushes against, and the bearing block is equipped with lower part backstop, and the 4th lip and lower part backstop of rubber ring are interference fitted.
Technical characteristic of the invention also resides in:
The sealing framework includes top beam, central sill and bottom beam, and the top beam includes top cross-bar and top vertical beam, it is described in Beam includes middle beam and middle part vertical beam, and the bottom beam includes base cross members and bottom vertical beam, and the top cross-bar is equipped with hook-shaped Protrusion, and seal groove is equipped with the hook-like groove cooperated with hooked projection, the inner sidewall abutting of the top vertical beam and bearing block is described Middle beam, middle part vertical beam, base cross members, bottom vertical beam mutually push against cooperation with the respective side walls of rubber ring respectively.
Inner ring is equipped with hierarchic structure, and rubber ring is equipped with the first lip, the second lip and third lip, first lip and hierarchic structure Roof interference fit, the side wall of the second lip and hierarchic structure is interference fitted, and the bottom wall of third lip and hierarchic structure is interference fitted.
Using above technical scheme, the present invention has following technological merit:
1. the top cross-bar is equipped with hooked projection, and seal groove is equipped with the hook-like groove cooperated with hooked projection, Ke Yiyou Effect prevents sealing ring from falling off.
2. using the above structure, rubber ring of the invention is between sealing framework and bearing block, and passes through sealing framework It is pushed against with bearing block, such structure, sealing framework and rubber ring is not had to Nian Jie, when installation, only a need will be close The seal groove of envelope skeleton and bearing outer ring is worked good, and then rubber ring is placed between sealing framework and bearing block, then solid Tight bearing block may make rubber ring to be stably fixed on corresponding position.
3. multiple bending mechanisms are arranged in sealing framework of the invention, while rubber ring is also provided with into matched shape, in this way The contact area between rubber ring and sealing framework can be increased, increase its mutual frictional force, so that rubber ring works When, position is more preferable with stabilized seal performance.
4. mutually being pushed against between the lateral wall of bearing block inner sidewall and rubber ring of the invention, while the 4th lip of rubber ring It is interference fitted between the backstop of bearing block, very big stiction can be generated in this way, and transmit by rubber ring, sealing framework Onto bearing outer ring, it can thus effectively reduce between bearing outer ring and bearing block and relatively rotate, while also can effectively prevent Only sealing ring falls off.

Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples:
Embodiment 1: as shown in Figure 1, Figure 2 and Fig. 3, Fig. 4 shown in, a kind of ball bearing of usheing to seat facilitating installation, including ball bearing with Bearing block 1, the bearing block 1 are formed by two half, bearing, and two half, bearing can be fixed by screw rod and nut.It is described Bearing block is equipped with lower part backstop 11.The bearing block is additionally provided with oil nozzle 3 and oilhole 4, the corresponding position of the outer ring 21 of the bearing Equipped with oilhole 5.
The lateral wall of the outer ring 21 is equipped with seal groove, is equipped with sealing framework 6, the sealing framework 6 in the seal groove Outside be equipped with rubber ring 7, the inner sidewall of the lateral wall of the rubber ring 7 and bearing block 1 pushes against
The sealing framework 6 includes top beam 61, central sill 62 and bottom beam 63, and the top beam 61 includes top cross-bar 611 and top Portion's vertical beam 612, the central sill 62 include middle beam 621 and middle part vertical beam 622, and the bottom beam 63 includes 631 He of base cross members Bottom vertical beam 632, the top cross-bar 611 is equipped with hooked projection 64, and seal groove is equipped with the hook-like groove cooperated with hooked projection.
The inner sidewall of the top vertical beam 612 and bearing block 1 pushes against, the middle beam 621, middle part vertical beam 622, bottom Crossbeam 631, bottom vertical beam 632 mutually push against cooperation with the respective side walls of rubber ring 7 respectively.
Inner ring 22 is equipped with hierarchic structure, and rubber ring 7 is equipped with the first lip 71, the second lip 72, third lip 73 and the 4th lip 74, institute It states the first lip 71 and the roof 221 of hierarchic structure is interference fitted, the second lip 72 and the side wall 222 of hierarchic structure are interference fitted, the Three lips 73 and the bottom wall 223 of hierarchic structure are interference fitted.The 4th lip 74 and the lower part backstop 11 of rubber ring are interference fitted.
In fact, the lateral wall of rubber ring 7 will generally exceed the top vertical beam of sealing framework, in this way, in assembling, by After the elasticity of rubber ring, the inner sidewall abutting of the lateral wall and bearing block of rubber ring, it can be recessed inwardly so that deformation occurs, axis Holding seat still can inwardly push against the top vertical beam of steel ring skeleton, and can preferably push against rubber ring simultaneously.
4th lip bottom area of rubber ring can be all bigger than other lips, can increase itself and bearing block lower part backstop in this way Contact area, increase stiction, to accordingly reduce the relative movement between outer ring and bearing block.
Using above technical scheme, the present invention can effectively reduce opposite turn occurred between bearing outer ring and bearing block It is dynamic, while sealing ring being facilitated to install.
