Description
Technical Field
The utility model relates to a holder structure field of making, concretely relates to take holder structure of gland.
Background
When the existing rolling bearing works, particularly when the load is complex and the rolling bearing rotates at high speed, the retainer bears large centrifugal force, impact and vibration, large sliding friction exists between the retainer and the rolling bearing, and a large amount of heat is generated.
The combined effect of force and heat can lead to cage failure, and in severe cases, can cause cage burn and fracture. Therefore, the cage material is required to have good thermal conductivity, good wear resistance, small friction coefficient, smaller density, certain strength and toughness combination, better elasticity and rigidity, expansion coefficient similar to that of the rolling body and good processing property.
The retainer structure among the prior art guarantees the gland position with the friction force that interference fit produced between the pinhole, but the voussoir has great axial float when the product is high-speed rotatory, if be in again this moment under high low temperature state, the magnitude of interference between the pinhole reduces, has the risk that the gland deviate from, and if the magnitude of interference of increase pinhole then the difficult condition of assembling can appear.

the top of the supporting wedge block structure is provided with a top supporting surface, and the two sides of the top supporting surface are respectively provided with a first side inclined surface and a second side inclined surface;
a supporting cavity for supporting the wedge block structure to go deep is arranged in the supporting body of the retaining frame;
and elastic limiting structures are arranged on the side parts of the supporting wedge block structures, and the supporting wedge block structures are extended into the supporting cavity one by one and then limited through the elastic limiting structures corresponding to the single supporting wedge block structures.
In a preferred embodiment of the present invention, the elastic limiting structure is a spring limiting plate disposed obliquely relative to the direction of the support wedge structure.
In a preferred embodiment of the present invention, a plurality of mounting grooves are formed on the press cover, and the bottom of the supporting wedge structure is disposed in the mounting grooves.
