Abstract

The invention discloses a wear resistant potentiometer, comprising a shell and a potentiometer body arranged in the shell. The shell is a cylindrical structure. A shaft sleeve is arranged on the top of the shell. Multiple through holes are arranged on the side wall of the shell. A polytetrafluoroethylene coating is arranged on the inner wall of the shaft sleeve. According to the wear resistant potentiometer, a resistor is arranged into a folding line-shaped structure, so that the maximum value of the resistor is effectively increased; a sliding contact is connected with folding parts of the resistor, so that different precisions of the potentiometer can be set according to the number and the degree of the folding parts of the resistor, and the usage convenience is improved; and the wear resistant potentiometer has the advantages of simple and reasonable structure, good self-lubricating property, flexible rotation and no friction noise.

Description

technical field [0001] The invention belongs to the technical field of potentiometers, in particular to a wear-resistant potentiometer. Background technique [0002] The potentiometer is a resistive element with three terminals and the resistance value can be adjusted according to a certain change rule. A potentiometer usually consists of a resistor body and a movable brush. Most of the current potentiometers are covered by a casing to cover the components in the potentiometer, and the potentiometer is adjusted by a rotating rod extending into the casing. The potentiometer is installed on various devices for use and plays a role in adjustment. The rotating shaft of the existing rotary potentiometer will encounter the situation of inflexible rotation, which will cause wear and tear, and is accompanied by friction noise. It needs to drop a small amount of gasoline from the rotating shaft for lubrication, which is troublesome. Contents of the invention [0003] The purpose ...
