Need to realize the quick dispatch of bearing, such structure is unable to satisfy requirement, needs specially to increase to meet quick dispatch
Blowout patche internal diameter reduces axle journal, uses to meet, and which results in bearings when running at high speed blowout patche and axle journal occur opposite
Harmful sliding friction, and need roller system distance collar to pass through two sides blowout patche when axial locking and locked, excessive limits spacing
Ring section thickness makes the strength reduction of distance collar, the axial load resistant ability of direct influence bearing.
Summary of the invention
To solve the above problems, the present invention provides a kind of quick dispatch that can be realized bearing, blowout patche and roll neck are avoided
A kind of double-direction thrust ball bearing that limitation distance collar section thickness improves distance collar intensity, particular technique side are eliminated in nocuousness friction
Case are as follows:
Two end faces of a kind of double-direction thrust ball bearing, including blowout patche, seat ring, steel ball and retainer, the blowout patche are all provided with
There is rolling groove, the steel ball is located in retainer, and steel ball is located in the rolling groove of two end faces of blowout patche, the seat ring pair
Claim the both ends for being located at blowout patche, also to be provided with rolling groove on seat ring, the rolling groove of seat ring is pressed on steel ball；It further include stop collar, it is described
Stop collar is located at the inside of blowout patche and seat ring, and with blowout patche coaxial line, stop collar connect with blowout patche, and is whole knot with blowout patche
Structure, blowout patche are located at the axial center of stop collar；The outer diameter of the stop collar is less than the internal diameter of seat ring；The two of the stop collar
End face of the end face at end with the seat ring of blowout patche two sides far from steel ball is concordant.
By using above-mentioned technical proposal, the thickness of stop collar and the overall thickness of double-direction thrust ball bearing are consistent, stop collar
Distance collar can be enhanced to the axial locking of bearing, guarantee the bearing capacity of bearing axial direction.
Stop collar reduces the difficulty of processing of distance collar, improves the intensity of distance collar.
Stop collar is pressed on the shaft shoulder by distance collar, and stop collar and blowout patche follow axis to rotate synchronously, and is reduced sliding friction, is mentioned
In the high service life of bearing, reduce the damage of axis.
The internal diameter that the outer diameter of stop collar is less than seat ring facilitates the rotation of seat ring.
Stop collar and blowout patche are that overall structure can be improved intensity, avoid stop collar and blowout patche that sliding friction occurs.
The internal diameter of stop collar is less than the double not thrust ball bearings of outer diameter fast and easy dismounting of axis.
Preferably, the inner ring of the stop collar is equipped with continuous helicla flute.
By using above-mentioned technical proposal, helicla flute can facilitate the disassembly of stop collar, and can accommodate lubricating grease or lubrication
Oil prevents harmful friction to lubricate stop collar and axle journal.
Compared with prior art the invention has the following advantages:
A kind of double-direction thrust ball bearing provided by the invention can be realized the quick dispatch of bearing, avoid blowout patche and roll neck
Nocuousness friction, eliminates the limitation of distance collar section thickness, improves the intensity of distance collar.
Detailed description of the invention
