Abstract

The utility model discloses a bearing holder, including annular body and the rectangular switdh of evenly distributed on annular body, be equipped with the latch segment on the one end internal face of rectangular switdh, the width of latch segment is less than the width of the internal face at its place. The utility model discloses a be equipped with the latch segment on the one end internal face of rectangular switdh, the latch segment can play axial restriction and roll the locking effect that needle position moved, and kingpin motorium takes place skewly to make wearing and tearing inconsistent when avoiding installing, leads to producing behind the bearing atress card phenomenon of dying.

Description

A kind of needle bearing cage

Technical field

The utility model relates to a kind of needle bearing cage.

Background technique

Current automobile, engineering machinery owning amount are increasing, and every platform gearbox all needs to have mixed more than ten and overlaps needle bearing, and actual demand amount is very large, and market prospects are considerable.The retainer of needle bearing comprises ring body and is evenly distributed on the rectangular window on ring body, because window is rectangular, during installation, the needle roller centre of motion is easily departed from and is made wearing and tearing inconsistent, thus produce stuck phenomenon after causing shaft strength, affect working efficiency and the working life of needle bearing.Therefore be necessary to improve prior art.

Model utility content

The needle bearing cage that when the purpose of this utility model is to provide a kind of installation, the needle roller centre of motion can not be departed from, ensures the working efficiency of needle bearing, improves the working life of needle bearing.

The technological scheme realizing the utility model object is: a kind of needle bearing cage, comprises ring body and is evenly distributed on the rectangular window on ring body; One end internal face of described rectangular window is provided with locking block; The width of described locking block is less than the width of the internal face at its place.

The end face of the locking block on one end inwall of described rectangular window, the internal face of the other end of rectangular window, and keep away face in the both sides of rectangular window and be plane.

Four angles of the inwall of described rectangular window are equipped with curvilinear groove.

Have employed technique scheme, the utility model has following beneficial effect: one end internal face of (1) rectangular window of the present utility model is provided with locking block, locking block can play the locking effect of axially restriction needle roller displacement, when avoiding installing, the needle roller centre of motion is departed from and is made wearing and tearing inconsistent, produces stuck phenomenon after causing shaft strength.

(2) the utility model can ensure the working efficiency of needle bearing, improves the working life of needle bearing, and materials consumption is simultaneously few, and weight is lighter.

(3) four angles of the inwall of rectangular window of the present utility model are equipped with curvilinear groove, curvilinear groove not only can play location and prevent needle roller from producing tangential frost-heaves, the effect that trapped fuel improves needle bearing lubrication can also be played, reduce the surface friction drag of needle bearing, thus reach the effect of energy-conserving and environment-protective.

Embodiment

(embodiment 1)

See Fig. 1 to Fig. 4, the needle bearing cage of the present embodiment, comprise ring body 1 and be evenly distributed on the rectangular window 2 on ring body 1.

One end internal face of rectangular window 2 is provided with locking block 21.The width of locking block 21 is less than the width of the internal face at its place.The end face of the locking block 21 on one end inwall of rectangular window 2, the internal face of the other end of rectangular window 2, and keep away face in the both sides of rectangular window 2 and be plane.Four angles of the inwall of rectangular window 2 are equipped with curvilinear groove 22.

The locking block 21 of the rectangular window 2 of the needle bearing cage of the present embodiment can play the locking effect of axially restriction needle roller displacement, and when avoiding installing, the needle roller centre of motion is departed from and worn and torn inconsistent, produces stuck phenomenon after causing shaft strength.Ensure the working efficiency of needle bearing, improve the working life of needle bearing, materials consumption is simultaneously few, and weight is lighter.Curvilinear groove 22 not only can play location and prevent needle roller from producing tangential frost-heaves, can also play the effect that trapped fuel improves needle bearing lubrication, reduce the surface friction drag of needle bearing, thus reach the effect of energy-conserving and environment-protective.

Above-described specific embodiment; the purpose of this utility model, technological scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.

Claims

1. a needle bearing cage, comprises ring body (1) and is evenly distributed on the rectangular window (2) on ring body (1); It is characterized in that: one end internal face of described rectangular window (2) is provided with locking block (21); The width of described locking block (21) is less than the width of the internal face at its place.

2. a kind of needle bearing cage according to claim 1, it is characterized in that: the end face of the locking block (21) on one end inwall of described rectangular window (2), the internal face of the other end of rectangular window (2), and keep away face in the both sides of rectangular window (2) and be plane.

3. a kind of needle bearing cage according to claim 1, is characterized in that: four angles of the inwall of described rectangular window (2) are equipped with curvilinear groove (22).
