Description
Technical field
The present invention relates to the pressure bearing of field of bearings, more particularly to a kind of pair of ball.
Background technology
Bearing is a kind of important parts in contemporary plant equipment, and its major function is the mechanical rotary body of support, drop
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 occurs radial impact, structure is easily damaged, stability
Difference is, it is necessary to strengthen.
The content of the invention
It is an object of the invention to provide the pressure bearing of a kind of pair of ball, strengthen structural strength axially and radially, carry
The fast run stability of rise.
For up to this purpose, the present invention uses following technical scheme：
A kind of pressure bearing of pair of ball, including：Upper blowout patche, bottom race and the first retainer, first retainer are arranged on
Between upper blowout patche and bottom race, a circle is located between upper blowout patche and bottom race first is arranged at intervals with first retainer
It is provided with the outside of ball, the upper blowout patche on the inside of the radial spacing loop extended in bottom race, the radial spacing loop and upper axle
It is provided with the second retainer, second retainer and is arranged at intervals with positioned at radial spacing loop inwall and upper axle between circle outside
The second ball between ring 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.
Beneficial effects of the present invention：The pressure bearing of a kind of pair of ball, is rolled using the first ball to upper blowout patche bottom
Dynamic support, it is ensured that axial load ability, recycles the second ball carry out rolling support cylindrical to upper blowout patche, strengthens radial load energy
Stability in use under power, the comprehensive operating mode of lifting.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
Technical scheme is further illustrated with reference to Fig. 1 and by specific embodiment.
A kind of pressure bearing of pair of ball, including：Upper blowout patche 1, the retainer 2 of bottom race 4 and first, first retainer
2 are arranged between blowout patche 1 and bottom race 4, and a circle is arranged at intervals with first retainer 2 positioned at upper blowout patche 1 and lower seat
The first ball 3 between circle 4, carries out rolling support, it is ensured that axial load ability using 3 pairs of upper bottoms of blowout patche 1 of the first ball,

It is provided with the second retainer 11, second retainer 11 and is arranged at intervals with radial spacing loop 8 between the outside of blowout patche 1
The second ball 6 between wall and the outer wall of upper blowout patche 1.Using 6 pairs of cylindrical carry out rolling supports of upper blowout patche 1 of the second ball, strengthen footpath
To load-bearing capacity, the stability in use under the comprehensive operating mode of lifting.
In the present embodiment, the upper blowout patche 1 is located at the top of bottom race 4, and upper blowout patche 1 is connected with rotating shaft, carries out the rotation of rotating shaft
Support, the axial force and radial load of countershaft carry out load.
In the present embodiment, the upper bottom of blowout patche 1 and the top of bottom race 4 are respectively arranged with corresponding with the first ball 3
First annular groove 10, first annular groove 10 strengthens the spacing of the first ball 3, lifts the run stability of the first ball 3.
In the present embodiment, it is respectively arranged with the inwall of radial spacing loop 8 and the upper outer wall of blowout patche 1 and 6 pairs of the second ball
The second annular groove 12 answered, carries out spacing to the second ball 6, improves the run stability of the second ball 6.
In the present embodiment, oil baffle 5 is provided with the top of the endoporus of bottom race 4, it is to avoid the oil leak on bottom race 4
Problem, strengthens the lubrication of the first ball 3.
In the present embodiment, mounting groove 7 corresponding with radial spacing loop 8 is provided with the bottom race 4, lifting is radially spacing
The installation convenience of circle 8, the bottom of bottom race 4 is provided with the fastening bolt 9 being connected with radial spacing loop 8, and sound construction is torn open
Unload maintenance facility.
Above content is only presently preferred embodiments of the present invention, for one of ordinary skill in the art, according to the present invention's
Thought, will change in specific embodiments and applications, and this specification content should not be construed as to the present invention
Limitation.
