Furthermore, the oil nozzle hole and the horizontal line are opposite to the bearing inner ring slope at a contact angle of 30 degrees, lubricating oil is pressed in from the oil injection semi-counter bore of the outer spacer sleeve by utilizing high pressure during the lubrication of the ultra-high speed bearing during the paired assembly, and then the lubricating oil is ejected out through the oil nozzle hole, so that the lubricating oil is sprayed onto the bearing inner ring slope of the ultra-high speed bearing under the action of the pressure and is not directly sprayed onto the steel ball, and the vibration and the noise are reduced.
Furthermore, the bottom of the oil injection semi-counter bore of the oil injection nozzle hole is provided with two oil injection nozzle holes, and the two oil injection nozzle holes are symmetrical to each other.
Furthermore, the internal surface of outer spacer is provided with the lubrication groove, is provided with the lubrication groove through the internal surface of outer spacer and stores lubricating oil.
Furthermore, an inner partition plate is arranged on the lower side of the outer spacer bush, and the inner partition plate is arranged on the lower side of the outer spacer bush to effectively separate and block.
Furthermore, the ultrahigh-speed bearings are assembled on two sides of the outer spacer in pairs, and the ultrahigh-speed bearings are assembled on two sides of the outer spacer in pairs, so that the rotation stability of the bearings is effectively improved.
Further, the inner partition plate and the lubricating groove form a lubricating cavity.
The utility model has the advantages that:
1. the lubricating oil is injected from the oil injection semi-counter bore of the outer spacer sleeve by utilizing high pressure to lubricate the ultra-high speed bearing during paired assembly, and then the lubricating oil is injected out through the oil injection hole, and is sprayed onto the bearing inner ring slope of the ultra-high speed bearing under the action of pressure instead of being directly sprayed onto the steel ball, so as to reduce vibration and noise;
