Description
Technical field
It the utility model is related to field of bearings, more particularly to a kind of pressure bearing of double balls.
Background technology
Bearing is a kind of important parts in contemporary plant equipment, and its major function is the mechanical rotary body of support, is dropped
Coefficient of friction in low mechanical rotary body motion process, and ensure its rotating accuracy.
By the difference of motor element frictional property, bearing can be divided into rolling bearing and the major class of sliding bearing two, wherein rolling
Bearing is normalized, seriation, but its radial dimension, vibration and noise are larger compared with sliding bearing, and price is also higher.
Thrust ball bearing is generally made up of blowout patche, seat ring, retainer and steel ball, can bear axial load, it can be difficult to
Larger radial load is born, when radial load is excessive, rotating speed is high or radial impact occurs, structure is easily damaged, stability
Difference is, it is necessary to strengthen.
Utility model content
The purpose of this utility model is to provide a kind of pressure bearing of double balls, and the structure strengthened axially and radially is strong
Degree, lift the stability that runs at high speed.
To use following technical scheme up to this purpose, the utility model：
A kind of pressure bearing of double balls, including：Upper blowout patche, bottom race and the first retainer, described first keeps setting up
Put between upper blowout patche and bottom race, a circle is arranged at intervals with first retainer between upper blowout patche and bottom race
First ball, is provided with the radial spacing loop extended in bottom race on the outside of the upper blowout patche, on the inside of the radial spacing loop with
Be provided with the second retainer between on the outside of upper blowout patche, be arranged at intervals with second retainer positioned at radial spacing loop inwall with
The second ball between upper blowout patche outer wall.
Wherein, the upper blowout patche is located at the top of bottom race.
Wherein, the upper blowout patche bottom and bottom race top are respectively arranged with corresponding with the first ball first annular
Groove.
Wherein, the radial spacing loop inwall is with being respectively arranged with the second ring corresponding with the second ball on upper blowout patche outer wall
Shape groove.
Wherein, it is provided with oil baffle at the top of the bottom race endoporus.
Wherein, mounting groove corresponding with radial spacing loop is provided with the bottom race, the bottom race bottom is provided with
The fastening bolt being connected with radial spacing loop.
The beneficial effects of the utility model：A kind of pressure bearing of double balls, upper blowout patche bottom is entered using the first ball
Row rolling support, it is ensured that axial load ability, recycle the second ball carry out rolling support cylindrical to upper blowout patche, strengthen radially negative
Lotus ability, lift the stability in use under comprehensive operating mode.
