Abstract
The utility model discloses a high speed thrust ball bearing. A fan-shaped groove is formed in one side of a seat ring relative to a shaft ring, the arc of the fan is concentric with the arc of a shaft seat, two roller pins are arranged in the groove, the roller pins are in tangency with the lateral wall of the groove and the bottom side of the groove, and a rolling ball is arranged between the two roller pins and in contact with the roller pins. The rolling ball is in contact with the arc outer wall of the groove, a gap is arranged between the rolling ball and the bottom face of the groove, the rolling ball is higher than the surface of the seat ring, an abrasion-resistant coating coats the arc outer wall of the groove, a rolling ball rack is arranged between the two roller pins, friction of the seat ring is reduced, the rolling body is in contact with the abrasion-resistant coating, and the abrasion of the rolling body is reduced to the minimum degree.
Description
Technical field
The utility model relates to a kind of bearing, and more particularly, it relates to a kind of high speed thrust ball bearing.
Background technique
Thrust ball bearing in mechanical rotating machinery, apply very extensively, especially on the axle of High Rotation Speed, but common thrust ball bearing in the time of rotation at a high speed often due to the more rotation of piece of the excessive thrust ball bearing of frictional force, thereby limit the rotation of axle, and this bearing wear resistance not easily damages, and make to stablize not in high speed rotating.
Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide the high speed that a kind of frictional force is little, wear resistance good, speed is fast, operate steadily thrust ball bearing.
For achieving the above object, the utility model provides following technological scheme: a side of the relative blowout patche of described seat ring is provided with fan-shaped groove, described fan-shaped circular arc is concentric with the circular arc of axle bed, in described groove, be provided with two needle rollers, described needle roller respectively with recess sidewall, groove floor is tangent, described rolling ball is arranged between two needle rollers, described rolling ball contacts with needle roller, described rolling ball contacts with groove arc outer wall, described rolling ball and groove floor are provided with gap, described rolling ball surface exceeds raceway surfaces, on described groove arc outer wall, scribble wear resistant coating.
By adopting technique scheme, rolling ball-collecting rack, between two needle rollers, has reduced and the frictional force of seat ring, and rolling element contacts with wear resistant coating, makes the wearing and tearing reduction of rolling element minimum.
The utility model is further set to: the groove arc outer wall that described needle roller is relative is provided with the through hole identical with needle roller diameter.
By adopting technique scheme, when needle roller is installed, needle roller can be inserted as in scalloped recess by through hole, make to install needle roller more convenient.
The utility model is further set to: the groove arc inner wall that described needle roller is relative is provided with the positioning hole identical with needle roller diameter.
By adopting technique scheme, make needle roller can insert positioning hole, make needle roller in groove, can not cause because of the rolling of rolling ball needle roller dislocation, improve the stability of needle roller.
The utility model is further set to: described wear resistant coating is polyether-ether-ketone wear resistant coating.
By adopting technique scheme, polyether-ether-ketone wear resistant coating has high strength, high tenacity and high-fire resistance, and wear resistance is outstanding, and can also selflubricating, improves the wear resistance of bearing, makes bearing need not add lubricant oil.

Embodiment
Referring to figs. 1 through Fig. 3, the utility model high speed thrust ball bearing embodiment is described further.
A kind of high speed thrust ball bearing, comprise seat ring 1, blowout patche 3, rolling ball 2, described rolling ball 2 is arranged between seat ring 1 and blowout patche 3, one side of described seat ring 1 relative blowout patche 3 is provided with fan-shaped groove, described fan-shaped circular arc is concentric with the circular arc of axle bed, in described groove, be provided with two needle rollers 4, described needle roller 4 respectively with recess sidewall, groove floor is tangent, described rolling ball 2 is arranged between two needle rollers 4, described rolling ball 2 contacts with needle roller 4, described rolling ball 2 contacts with groove arc outer wall, described rolling ball 2 is provided with gap with groove floor, described rolling ball 2 surfaces exceed seat ring 1 surface, on described groove arc outer wall, scribble wear resistant coating 8, 2 of rolling balls are between two needle rollers 4, rolling ball 2 and two needle rollers 4 do rolling friction, rolling has reduced the frictional force with seat ring 1, rolling element contacts with wear resistant coating 8, wear resistant coating 8 has good wear resistance, and friction factor is lower, the wearing and tearing of rolling ball 2 with groove arc outer wall are effectively reduced, increase the rolling rate of rolling ball 2, rolling ball 2 surfaces exceed seat ring 1 and contact with blowout patche 3, rolling ball 2 and blowout patche 3, needle roller 4, groove arc outer wall forms 4 contacts, effectively raise the stability of bearing rotary, described scalloped recess 5 is six and has improved antiwhip.
The groove arc outer wall that needle roller 4 is relative is provided with the through hole 6 identical with needle roller 4 diameters, when needle roller 4 is installed, needle roller 4 can be inserted as in scalloped recess 5 by through hole 6, makes to install needle roller 4 more convenient.
The groove arc inner wall that needle roller 4 is relative is provided with the positioning hole 7 identical with needle roller 4 diameters, makes needle roller 4 can insert positioning hole 7, makes needle roller 4 can not cause needle roller 4 to misplace because of the rolling of rolling ball 2 in groove, has improved the stability of needle roller 4.
Wear resistant coating 8 is polyether-ether-ketone wear resistant coating 8, and polyether-ether-ketone wear resistant coating 8 has high strength, high tenacity and high-fire resistance, and wear resistance is outstanding, and can also selflubricating, improves the wear resistance of bearing, makes bearing need not add lubricant oil.
