Description
Technical field
The invention belongs to technical field of bearings, more particularly to a kind of needle bearing.
Background technology
Needle bearing is the roller bearing with cylindrical roller, and with respect to its diameter, roller was not only thin but also long, existing needle bearing
Because its needle roller often lacks lubrication, cause the noise when rotating larger, and bearing rotary resistance is big, the life-span is low.
The content of the invention
To solve needle bearing of the prior art because its needle roller often lacks lubrication, cause in rotation noise compared with
Greatly, the problem of and bearing rotary resistance is big, and the life-span is low, now provides a kind of needle bearing.
The technical solution adopted in the present invention is a kind of needle bearing to achieve the above object, including outer ring and inner ring, institute
State and some needle rollers are filled between outer ring and inner ring, the needle roller contacts with the inner peripheral surface of outer ring, on the outer peripheral face of the outer ring
Annular groove is offered, the annular air-pocket to match with it is provided with the annular groove, the annular air-pocket and annular are recessed
The cell wall of groove is fixedly connected, and closed shoe cream room, the inner peripheral surface of the outer ring are formed between the annular air-pocket and annular groove
On be densely covered with some micropores, the micropore is connected with shoe cream room, and the note connected with shoe cream room is offered on the end face of the outer ring
Oily passage, the oiling passage is interior to be provided with plug.
In this programme when needle roller lacks lubricating oil, the frictional force between needle roller and outer ring and inner ring becomes big, so as to cause
The bearing is drastically generated heat, and the expansion of annular air-pocket can be caused after bearing heating, can be oppressed after annular air-pocket expansion in shoe cream room
Lubricating oil is by micropore, and the inner peripheral surface in outer ring forms high pressure oil film, on the one hand high pressure oil film can reduce rolling with holding needle roller
Frictional force between pin and outer ring, on the other hand needle roller can be caused to obtain sufficient lubrication, so as to lower needle roller and inner ring and outer
Frictional force between circle, reduce noise and improve the service life of the bearing.
Further, stop collar is arranged with the outer peripheral face of the outer ring, passes through screw between the stop collar and outer ring
It is fixedly connected, passes through the setting of stop collar so that during annular air-pocket expanded by heating, annular air-pocket deforms towards shoe cream room.
Further, the plug is threadedly coupled with oiling passage.
Further, it is fixedly connected between the annular air-pocket and the cell wall of annular groove by glue sealing.
In order to improve radiating effect, further, the inner ring runs through along its axis direction heat emission hole.
Beneficial effect：The expansion of annular air-pocket can be caused after its heating of the needle bearing of the present invention, after annular air-pocket expansion
The lubricating oil in shoe cream room can be oppressed by micropore, and the inner peripheral surface in outer ring forms high pressure oil film, high pressure oil film on the one hand can
With holding needle roller, the frictional force between needle roller and outer ring is reduced, on the other hand needle roller can be caused to obtain sufficient lubrication, so as to subtract
Frictional force between low needle roller and inner ring and outer ring, reduce noise and improve the service life of the bearing.

Embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These accompanying drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention, direction and reference (for example,
Upper and lower, left and right, etc.) can be only used for helping the description to the feature in accompanying drawing.Therefore, not adopted in restrictive, sense
With detailed description below, and claimed theme is only limited by appended claims and its equivalents
Scope.
Embodiment 1
As illustrated in fig. 1 and 2, a kind of needle bearing, including outer ring 1 and inner ring 2, are filled between the outer ring 1 and inner ring 2
Some needle rollers 3, the needle roller 3 are contacted with the inner peripheral surface of outer ring 1, and annular groove is offered on the outer peripheral face of the outer ring 1, described
The annular air-pocket 4 to match with it is provided with annular groove, the annular air-pocket 4 is fixedly connected with the cell wall of annular groove,
Closed shoe cream room 1-1 is formed between the annular air-pocket 4 and annular groove, is densely covered with the inner peripheral surface of the outer ring 1 some
Micropore 1-2, the micropore 1-2 are connected with shoe cream room 1-1, and the note connected with shoe cream room 1-1 is offered on the end face of the outer ring 1
Plug 6 is provided with oily passage 1-3, the oiling passage 1-3, the material of annular air-pocket 4 can be rubber.
Stop collar 5 is arranged with the outer peripheral face of the outer ring 1, is fixed between the stop collar 5 and outer ring 1 by screw 7
Connection, passes through the setting of stop collar 5 so that during 4 expanded by heating of annular air-pocket, annular air-pocket 4 deforms towards shoe cream room 1-1.
The plug 6 is threadedly coupled with oiling passage 1-3.
It is fixedly connected between the annular air-pocket 4 and the cell wall of annular groove by glue sealing.
The inner ring 2 runs through along its axis direction heat emission hole 2-1.
Periodically outward winding plug 6 and lubricating oil is added into shoe cream room 1-1 by oiling passage 1-3, again will after addition
Plug 6 is tightened on oiling passage 1-3.
Above-mentioned needle bearing difference with the prior art is：When needle roller 3 lacks lubricating oil, needle roller 3 and outer ring 1 and interior
Frictional force between circle 2 becomes big, so as to cause the bearing drastically to generate heat, and can cause the expansion of annular air-pocket 4 after bearing heating,
The lubricating oil in shoe cream room 1-1 can be oppressed after the expansion of annular air-pocket 4 by micropore 1-2, and the inner peripheral surface in outer ring 1 forms high pressure
On the one hand oil film, high pressure oil film can be reduced the frictional force between needle roller 3 and outer ring 1, on the other hand can be made with holding needle roller 3
Obtain needle roller 3 and obtain sufficient lubrication, so as to lower the frictional force between needle roller 3 and inner ring 2 and outer ring 1, reduce noise and improve and be somebody's turn to do
The service life of bearing.
The above-mentioned desirable embodiment according to the present invention is enlightenment, complete by above-mentioned description, relevant staff
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention'.This invention it is technical
Scope is not limited to the content on specification, it is necessary to determines its technical scope according to right.
