For solving above-mentioned technical problem, the technical scheme that the utility model uses is: provide a kind of fretting wear little
Potentiometer, it is characterised in that including: lower house, upper shell, described upper shell top is provided with axle sleeve, described lower casing
Form a cavity between body and upper shell, described cavity inside be provided with rotating shaft, conduction revolving fragment, the first fixed pin piece, the
Two fixed pin pieces, dynamic pin sheet and circular arc resistance body, described rotating shaft matches with described axle sleeve, described rotating shaft bag
Including metal inside and non-graphite outer layers, the first described fixed pin piece and the second fixed pin piece are connected to circular arc resistance
It is provided with wear-resisting lubrication on the contact surface of the two ends of body, described axle sleeve and rotating shaft, and the contact surface of lower house and rotating shaft
Coating, described wear-resisting lubricant coating is the mixture of polytetrafluoroethylene (PTFE), molybdenum bisuphide and polyamide-imide resin.
In one preferred embodiment of the utility model, described metal inside is stainless steel.
In one preferred embodiment of the utility model, described non-graphite outer layers is soft graphite.
In one preferred embodiment of the utility model, described metal inside is connected by gluing with non-graphite outer layers.
In one preferred embodiment of the utility model, the polytetrafluoroethylene (PTFE) that described wear-resisting lubricant coating comprises 20% is moulded
Property lubricant, 30% molybdenum bisuphide solid lubricant and polyamide-imide resin.
The beneficial effects of the utility model are: potentiometer provided by the utility model uses dual lubrication, utilizes graphite
