Being slidably connected on groove, connection cone and voussoir.Voussoir is connected with cone by T-shaped bar, can form gap therebetween,
Gap value therein can effectively allow lubricating oil to form oil film between T-shaped bar and T-slot, be effectively protected contact surface, reduce
Increase lubricates again for friction so that device has more wearability.
Oil circuit separator is loaded onto in the outer surface of lubrication ring, between the oil circuit separator that the outer surface of lubrication ring is provided with can be provided
Connect formula fuel feeding so that lubrication two oil inlets of ring will not work simultaneously, greatly save oil consumption；In the outside table plane peace of voussoir
Dress is installed with outer mold piece, is effectively prevented the abrasion and deformation of the outer surface of voussoir；The material selection copper of T-shaped bar is closed
Gold, with good lubricating and wear-resisting, and oil absorption is good, and various intensity also meet job requirement.
Beneficial effect：The utility model has obvious beneficial effect relative to prior art, and the technical program is in cone table
Face is provided with T-slot, and T-shaped bar is fixed on voussoir, and voussoir can be slided by T-shaped bar along T-slot, and gap value therein can have
What is imitated allows lubricating oil to form oil film between T-shaped bar and T-slot, is effectively protected contact surface, and reducing friction, increase lubricates again；Profit
The oil circuit separator that the outer surface of slip ring is provided with can provide indirect type fuel feeding so that two oil inlets of lubrication ring will not be while work
Make, greatly save oil consumption；The table Plane Installation of voussoir is fixed with outer mold piece, is effectively prevented the abrasion of the outer surface of voussoir
And deformation, the material of T-shaped bar uses copper alloy, and the material has good lubricating and wear-resisting in itself, and oil absorption is good, full
The various working strength requirements of foot.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
The utility model is further explained below in conjunction with the accompanying drawings.
As shown in figure 1, the front end of support ring 8 is on the sleeve of the expanding pull bar of connecting cantilever, big end and the lubrication of cone 3
