By using above-mentioned technical proposal, ratio between the groove-root diameter and notch bore of oil storage tank 0.8-0.9 it
Between, by the way that the groove groove internal diameter of oil storage tank and notch bore are set using above-mentioned knot ratio, both ratio is being arranged on 0.8
When following, the outflow of lubrication oil being stored in oil storage tank should not be made, at set both comparisons more than 0.9, notch mouth
Footpath is excessive, and lubricating oil has a too fast loss when easy, and when both ratio is arranged between 0.8-0.9, enter with steel ball
When row coordinates, the effect of oil sealing is easily formed at notch, then reduces the loss of lubricating oil in oil storage tank, and with steel ball
Rotation, can also to form oil film on steel ball, so as to improve lubricant effect.
The utility model is further arranged to：Each pillar is provided with some conflict blocks, and the section of conflict block is in arc-shaped.
By using above-mentioned technical proposal, each pillar is provided with some conflict blocks, and the section of conflict block is in arc-shaped, is passed through
Some conflict blocks being provided with each pillar, it is ensured that the inner ring of bearing and the limit effect of outer ring, and conflict block is set
For convex structure, then the abrasion brought during installation is reduced.
The utility model is further arranged to：The retainer support body and retainer end cap use aluminum alloy materials system
Into.
By using above-mentioned technical proposal, retainer support body and retainer end cap are made of aluminum alloy materials, are led to
To cross and retainer support body and retainer end cap are made of aluminum alloy materials, aluminum alloy materials have good plasticity, and
And possess good thermal conductivity, it is used to guarantee frame support body and retainer end cap, then further increase retainer
Support body and the thermal conductivity for keeping end cap, then ensure that good using effect.
Brief description of the drawings
Fig. 1 is a kind of dimensional structure diagram of retainer embodiment of the utility model.
Fig. 2 is a kind of structural representation of the oil storage tank of retainer embodiment of the utility model.
Embodiment
A kind of retainer embodiment of the utility model is described further referring to figs. 1 to Fig. 2.
