It is provided with wearing plate under HSM between lower end sphere and lower support plate component, wearing plate and upper bracket plate component shape on described HSM
Into upper friction pair, wearing plate forms lower friction pair with lower support plate component under described HSM.
Compared with prior art, the beneficial effects of the invention are as follows：
1st, stable friction performance.The friction pair stable friction performance that HSM high-abrasive materials are formed with bearing connecting plate in the present invention, and
Without coating silicone grease, surface of friction pair cleaning, stable friction performance can be kept.
2nd, HSM material properties are superior, and compressive resistance is high, more than 220N/mm2, ensure that the weight capacity of bearing；In addition,
In the case where bearing equal vertical load, using this high-abrasive material, the pressure-bearing projected area and bearer for forming friction pair can be reduced
Volume, raw material are saved, and saved installing space；And HSM density of material is small, under equal load-up condition, what is used is resistance to
It is smaller to grind material weight, bearing deadweight can be reduced.
