2nd, it using the aligning structure of waveform spring, but to be used in combination with shell, complicated, technique is cumbersome；
3rd, using the aligning structure of rubber sleeve, product can automatically reset when pre-tightening insufficient, and aligning performance is bad, uses the later stage
Quick abrasion, service life reduction.
Invention content
The present invention mainly solves the deficiencies in the prior art, provides a kind of simple in structure, raising release bearing tune
A kind of release bearing and its production technology with flower pattern spring that mental and physical efforts are stablized.
The above-mentioned technical problem of the present invention is mainly what is be addressed by following technical proposals：
A kind of release bearing with flower pattern spring, including center, the left end of the center is cased with inner ring, described
Outer ring is set with outside inner ring, retainer is equipped between the inner ring and outer ring, steel ball is equipped in the retainer, in described
The heart is covered being equipped with flower pattern spring between inner ring, and the inner wall of the flower pattern spring and outer ring is resilient supporting, the outer ring with it is interior
Retainer raceway is formed between circle, the grease baffle with outer ring inner wall elastic connection is equipped in the retainer raceway；
The flower pattern spring is distributed in round, and the flower pattern spring with center phase empty set is equipped in the flower pattern spring
Mounting hole, the inner wall of the flower pattern spring are equipped with equally distributed elastic support sheet, elasticity are equipped between adjacent spring support chip
Notch, the elastic support sheet are distributed in shape is folded upward at.
Preferably, the trapezoidal shape distribution in the longitudinal section of the elastic support sheet, the interior dog-ear of the elastic notch
In arc transition；The bottom end of the elastic support sheet is bearing diagonal piece, and the outer end of the elastic support sheet is supported for bending
Piece, the inclination angle of the bearing diagonal piece is 21 degree, and the junction of the bending support chip and bearing diagonal piece is in arc transition,

Preferably, it is sealed between the inner ring and outer ring by sealing ring.
By the punching and bending and molding to sheet metal, it is allowed to certain bending and angle, global shape can be appropriate
The inside for being installed on release bearing；Quenching treatment is carried out, allows sheet metal that can possess good elasticity；By flower pattern spring assembly
Inside release bearing, make it to generate appropriate pressure, pressure generates required after acting on the contact surface of two parts
One of main performance of frictional force, i.e. release bearing --- aligning force.
The aligning force of release bearing is one of its main performance, but its internal structure is generally compact, it is impossible to be placed
Conventional spring element is designed by our flower pattern spring, makes product interior our needs of can generating in a limited space
Suitable aligning force.Flower pattern spring is of less demanding to fitted position, and the active force that can be generated is more stable, different by changing
Angle, it may be convenient to increase or decrease active force, release bearing aligning force equipped with flower pattern spring is stablized；In addition, assembling
Frock clamp it is fairly simple, it is easy to assembly.
A kind of release bearing with flower pattern spring, carries out according to the following steps：
