Description
Technical Field
The utility model relates to the technical field of bearings, in particular to an improved precision bearing structure.
Background
The bearing is a component for fixing and reducing the load friction coefficient in the mechanical transmission process. It can also be said that the member for reducing the friction coefficient during power transmission and keeping the center position of the shaft fixed when the other members are moved relative to each other on the shaft.
The existing bearing ball retainer is easy to contact with balls after being worn for a long time, so that part of the balls are locked to cause the condition that the bearing cannot operate, and the defect exists.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the problem that the existing bearing retainer is easy to cause ball locking due to long-term wear, and provides an improved precision bearing structure.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the utility model provides a modified precision bearing structure, includes outer lane and inner circle, the both sides surface evenly distributed welding of inner circle has the connecting plate, the connecting plate is fixed with first holder and second holder through locking bolt, the inside of first holder and second holder is provided with the ball, and first holder and second holder are close to inside force application spring and the ejector pin of being provided with respectively in one side of ball, the tip of ejector pin is provided with the compensation end rod.
Preferably, the locking bolt is sleeved with a spreading spring, and two ends of the spreading spring respectively abut against the opposite sides of the first retainer and the second retainer.
Preferably, the end of the compensation end rod penetrates and extends to the outside of one side of the first retainer and the second retainer, and the end of the compensation end rod is abutted against the surface of the ball.
Preferably, the surfaces of the first retainer and the second retainer are uniformly distributed with semicircular grooves, and the balls are embedded in the semicircular grooves.
The utility model has the beneficial effects that: through including inner race both sides surface weld connecting plate, and through fixed first holder and the second holder of connecting plate, and through the fixed ball of first holder and second holder, prop open two sets of holders through strutting the spring, reduce the condition with the ball contact, set up force application spring simultaneously in the holder is inside, it is ejecting and conflict with the ball realization with the compensation end rod of ejector pin tip through force application spring, effectively reduced the contact point between holder and the ball, reduce the emergence of the wearing and tearing condition, and the compensation end rod is receiving the wearing and tearing back, under force application spring's effect, still can make compensation end rod and ball contact, therefore the precision and the life of bearing have been improved greatly, therefore, the clothes hanger is strong in practicability.
