Loading capability.
The utility model is further arranged to, and the lower press strip surface scribbles molybdenum disulfide.
In said structure, the friction between sleeve pipe and ceiling molding is discharged by roller bearing, but lower press strip is squeezed into by sleeve pipe
Also friction can be produced when between two roller bearings with sleeve surface, therefore molybdenum disulfide is coated with lower press strip surface, utilizes molybdenum disulfide
Lubricity reduce the friction between lower press strip and sleeve pipe.
The beneficial effects of the utility model：When ceiling molding and lower press strip closure squeezing bushing, roller bearing and casing-contact simultaneously make
Lower press strip is headed between two roller bearings, elongation caused by casing-tube elastic deformation is discharged by the rolling of roller bearing, so as to shut out
The abrasion of exhausted sleeve surface, sleeve pipe are sandwiched in the sealed faying face for pushing and inverted " u "-shaped wherein being formed between bar and two roller bearings, seal energy
Power greatly improves, simultaneously because ceiling molding rotates the elastic deformation resistance of relief sleeve in clamp sleeve by roller bearing, can be big
Width reduces resistance caused by valve rod rotation, and the molybdenum disulfide of press strip surface coating, reduces sleeve pipe to greatest extent under coordinating
Abrasion.
