Abstract
The utility model provides a kind of blowout patche band little rib type self-aligning thrust roller bearing, and object is gouge blowout patche raceway when eliminating roller assembling, improves efficiency of assembling.Concrete technical measures are: (4) little rib II does not arrange ball-loading hole, reduce little rib II (4) height, for 0.1 times of roller top diameter Dw1, (4) little rib II be the blunt angle [alpha] in slope, α=125
0.The utility model has the advantage of: cancel blowout patche little rib ball mouth, roller can be installed at any place of blowout patche, accelerates assembling speed; Gouge can not be produced to blowout patche raceway simultaneously, ensure that bearing accuracy.
Description
Technical field
The utility model relates to the little rib structure of blowout patche of self-aligning thrust roller bearing, is specifically related to a kind of blowout patche band little rib type self-aligning thrust roller bearing.
Background technique
As shown in Figure 1, (3) the little rib I of traditional blowout patche band little rib type self-aligning thrust roller bearing is with ball-loading hole, and because (3) little rib I is highly 0.2 times of roller top diameter Dw1, (3) higher, little rib I is vertical angle 90
0, therefore during assembling, roller, (2) to the blowout patche (1) raceway generation gouge at ball mouth place, affects working life and the running accuracy of bearing.
Summary of the invention
The utility model provides a kind of blowout patche band little rib type self-aligning thrust roller bearing, and object is gouge blowout patche raceway when eliminating roller assembling, improves efficiency of assembling.
Technical measures are: (4) little rib II does not arrange ball-loading hole, reduce little rib II (4) height, for 0.1 times of roller top diameter Dw1, (4) little rib II be the blunt angle [alpha] in slope, α=125
0.
The utility model has the advantage of: cancel blowout patche little rib ball mouth, roller can be installed at any place of blowout patche, accelerates assembling speed; Gouge can not be produced to blowout patche raceway simultaneously, ensure that bearing accuracy.
Accompanying drawing explanation
Fig. 1 is the blowout patche schematic diagram that little rib has ball-loading hole;
Fig. 2 is the blowout patche schematic diagram after little rib optimal design.
Mark in figure: blowout patche 1, roller 2, little rib I 3, little rib II 4.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.
As shown in Figure 2, the little rib II 4 of blowout patche band little rib type self-aligning thrust roller bearing does not arrange ball-loading hole, and roller can be installed at any place, accelerates assembling speed; Little rib II 4 is highly 0.1 times of roller top diameter Dw1, and reduce than the height of little rib I 3, little rib II 4 angle is by 90 of little rib I 3
0change into blunt angle [alpha]=125, slope
0; Due to the structural change of little rib II 4, when making to assemble, roller 2 comparatively can be smoothly through little rib II 4, can not produce gouge to blowout patche 1 raceway.
Claims (2)
1. a blowout patche band little rib type self-aligning thrust roller bearing, is characterized in that: (4) described little rib II does not establish ball-loading hole, and little rib II is (4) highly low, and (4) little rib II is the blunt angle [alpha] in slope.
2. blowout patche band little rib type self-aligning thrust roller bearing according to claim 1, is characterized in that: (4) described little rib II is highly 0.1 times of roller top diameter Dw1.
3. blowout patche band little rib type self-aligning thrust roller bearing according to claim 1, is characterized in that: described little rib II (4) blunt angle [alpha]=125, slope
0.
