Piece and circular arc resistance body, described rotating shaft 5 matches with described axle sleeve 3, and described rotating shaft 5 includes metal inside 6 and stone
Ink outer layer 7, the first described fixed pin piece and the second fixed pin piece are connected to the two ends of circular arc resistance body.
Described fluorographite layer 4 adheres to gluing in axle sleeve 3 inner surface, and fluorographite wearability is good, and the introducing of fluorine makes it
High temperature, at a high speed, the performance under high-load condition be better than graphite or molybdenum bisuphide, improve graphite under the conditions of there is no aqueous vapor
Greasy property.
Described non-graphite outer layers 7 material is expanded graphite, and this graphite is except having the chemical stability of native graphite, resisting
Outside the characteristics such as erosion, also having special flexibility and elasticity, good airproof performance, lubricity is high.
Described metal inside 6 is connected by epoxide-resin glue is gluing with non-graphite outer layers 7.
Potentiometer lubricity provided by the utility model is high, utilizes fluorographite and the dual lubrication of graphite, improves electricity
Greasy property under the conditions of sealing does not has aqueous vapor for the position device.
The foregoing is only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every
Utilize the equivalent structure that the utility model description made or equivalence flow process conversion, or be directly or indirectly used in other phases
The technical field closed, all in like manner includes in scope of patent protection of the present utility model.
