Description

High-power, energy-saving compressor tapered roller bearing
Technical field
The present invention relates to compressor and pump machines technical field, specifically a kind of high-power, energy-saving compressor circular cone Roller bearing.
Background technique
It is higher and higher to the demand and performance requirement of compressor with the fast development of national economy.In recent years, with The upgrading of compressor improves, and also increasingly harsher to its matched bearing technology index request, high-power, energy-saving compressor is matched Cover tapered roller bearing, it is desirable that comprehensive performance with higher in operation, therefore the mating serial bearing of independent development compressor It is to speed up the pragmatic choosing of Chinese national economy development.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of high-power, energy-saving compressor tapered roller bearing.
For achieving the above object, the invention adopts the following technical scheme:
A kind of high-power, energy-saving compressor tapered roller bearing, including outer ring, inner ring, retainer, rolling element, the bearing Inner ring large-flange is equipped with Oil Guide slope, and rolling element big end contact surface is equipped with oil storage cave, and rolling element ball basal plane is theoretical calculation ball basal plane 80%, contact angle be big contact angle.
Above-mentioned high-power, energy-saving compressor tapered roller bearing, oil storage cave diameter of phi are bearing large end face diameter 70%.
Compared with prior art, the invention has the benefit that bearing of the present invention is suitble to high speed speed conditions, pole can be born Big axial force, temperature is low when bearing working, and lubricant effect is good, improves bearing working efficiency and extends bearing service life.

Specific embodiment
Below in conjunction with specific embodiment, the present invention will be further described.
A kind of high-power, energy-saving compressor tapered roller bearing, including outer ring 1, inner ring 2, retainer 3, rolling element 4, The bearing inner race large-flange is equipped with Oil Guide slope 5, and α is 10 °, in bearing working, is conducive to lubricating oil entrance, increases lubrication effect Fruit, rolling element big end contact surface are equipped with oil storage cave 6, are conducive to Bearing inner oil storage, lubrication, reduce temperature rise.Meanwhile oil storage cave is not Can be excessive, otherwise Contact Ellipse can touch the edge in oil storage cave, and stress is caused to concentrate, and oil storage cave diameter of phi is that bearing large end face is straight The 70% of diameter.Rolling element ball basal plane is the 80% of theoretical calculation ball basal plane, avoids bearing because bearing very big axial force, and Contact Ellipse is super The original safety zone of bearing out is caused early fatigue (as shown in Figure 4), meanwhile, when also bearing being avoided to run at high speed, due to contact Area is larger, generates a large amount of heat, and temperature rise increases, and is unfavorable for bearing normal work, and contact angle is big contact angle, favorably Great axial force is born in bearing.
