Description

Self oiling bearing

Technical field

The utility model relates to a kind of bearing, and more particularly, it relates to a kind of self oiling bearing.

Background technique

Bearing is because it is simple in structure, easy to use, in mechanical field by general use, and very important of the maintenance of bearing in routine use process, and lubricated be our crucial step while normally using bearing, if do not lubricated, easily cause bearing wear, reduced the working life of bearing.

Model utility content

The deficiency existing for prior art, the purpose of this utility model is to provide a kind of bearing of selflubricating.

For achieving the above object, the utility model provides following technological scheme: a kind of self oiling bearing, comprise inner ring, outer ring and ball, described inner ring inside is provided with shoe cream room, the outer ring surface of described inner ring is provided with the oil outlet communicating with shoe cream room, the axial direction of described oil outlet points to the axis of inner ring, the inwall of described oil outlet is provided with two about the symmetrical chute of oil outlet axis, in two described chutes, be equipped with slide block and the thrust spring of slip, one end of described thrust spring is fixedly connected with one end of the relative chute of slide block, the other end of described thrust spring is fixedly connected with the bottom of chute, what described slide block slided is arranged in chute and one end of slide block protrusion and chute, in described oil outlet, be provided with the ring slider of slip, described ring slider is between chute and shoe cream room, in described shoe cream room, be provided with draught spring, one end of described draught spring is connected with one end of the relative shoe cream room of ring slider, the other end is connected with the inwall of shoe cream room, one end that described slide block protrudes from chute is the inclined-plane back to the lopsidedness of outer ring towards chute.

Preferably, the degree of depth of described chute is less than the length of slide block.

Preferably, one end of described inner ring is provided with the oil filler communicating with shoe cream room.

Preferably, described oil filler place is provided with the rubber stopper being sealed and matched with it.

Compared with prior art, the beneficial effects of the utility model are: when bearing does not carry out work, existence due to thrust spring, two slide blocks prop up mutually, at this moment oil outlet is just in time blocked by two slide blocks, oil in shoe cream room cannot flow out by oil outlet, and when bearing inner race rotates, existence due to centrifugal force, ring slider can be towards the direction motion of outer shroud, and along with the motion of ring slider, ring slider can contact with the chamfering on two slide blocks, and then slowly two ring sliders are pushed away in chute, at this moment between two slide blocks, just there is certain space, oil in shoe cream room will be thrown out of by gap in oil storage hole, thereby reach to the lubricated effect of ball, now draught spring is in extended state, when bearing stops operating, draught spring can slide ring slider towards the direction of shoe cream room, two slide blocks all can be promoted towards the direction away from chute by thrust spring, thereby two slide blocks have mutually and prop up, oil outlet is blocked.

Embodiment

Referring to figs. 1 through Fig. 4, the utility model self oiling bearing embodiment is described further.

A kind of self oiling bearing, comprise inner ring 3, outer ring 2 and ball 1, described inner ring 3 inside are provided with shoe cream room 31, the outer ring surface of described inner ring 3 is provided with the oil outlet 34 communicating with shoe cream room 31, the axial direction of described oil outlet 34 points to the axis of inner ring 3, the inwall of described oil outlet 34 is provided with two about the symmetrical chute 33 of oil outlet 34 axis, in two described chutes 33, be equipped with slide block 8 and the thrust spring 6 of slip, one end of one end chute 33 relative to slide block 8 of described thrust spring 6 is fixedly connected with, the other end of described thrust spring 6 is fixedly connected with the bottom of chute 33, what described slide block 8 slided is arranged in chute 33 and one end of slide block 8 protrusion and chute 33, in described oil outlet 34, be provided with the ring slider 5 of slip, described ring slider 5 is between chute 33 and shoe cream room 31, in described shoe cream room 31, be provided with draught spring 4, one end of one end shoe cream room 31 relative to ring slider 5 of described draught spring 4 is connected, the other end is connected with the inwall of shoe cream room 31, one end that described slide block 8 protrudes from chute 33 is the inclined-plane 81 towards chute 33 lopsidedness of 2 back to outer ring.

When bearing does not carry out work, existence due to thrust spring 6, two slide blocks 8 prop up mutually, at this moment oil outlet 34 is just in time blocked by two slide blocks 8, oil in shoe cream room 31 cannot flow out by oil outlet 34, and when bearing inner race 3 rotates, existence due to centrifugal force, ring slider 5 can be towards the direction motion of outer shroud, and along with the motion of ring slider 5, ring slider 5 can contact with the chamfering on two slide blocks 8, and then slowly two ring sliders 5 are pushed away in chute 33, at this moment between two slide blocks 8, just there is certain space, oil in shoe cream room 31 will be thrown out of by gap in oil storage hole, thereby reach to the lubricated effect of ball 1, now draught spring 4 is in extended state, when bearing stops operating, draught spring 4 can slide ring slider 5 towards the direction of shoe cream room 31, two slide blocks 8 all can be promoted towards the direction away from chute 33 by thrust spring 6, thereby two slide blocks 8 have mutually and prop up, oil outlet 34 is blocked.

The degree of depth of chute 33 is less than the length of slide block 8, the stroke of ring slider 5 is played to the effect of restriction, prevent fuel-displaced too much, by preventing that ring slider 5 from being blocked by slide block 8 and cannot reset.

One end of inner ring 3 is provided with the oil filler 32 communicating with shoe cream room 31, when oil in shoe cream room 31 is few, by oil filler 32, gives the interior oiling of shoe cream room 31.

Oil filler 32 places are provided with the rubber stopper 7 being sealed and matched with it, when not needing oiling, by rubber stopper 7, block oil filler 32, prevent that some foreign matters from entering shoe cream room 31.
