Abstract

The invention discloses a shaft sleeve abrasion testing device under a special gas atmosphere. The shaft sleeve abrasion testing device comprises a power transmission part, a sealing part, a loading part, a test piece clamping part and a test processing part according to functions. The device disclosed by the invention can realize constant loading; a manner of combining lever loading and electromagnetic loading is used for carrying out radial loading and a rolling guide rail is used for reducing the radial friction force in a loading process; the influences of an outer friction force are reduced to be the lowest through cooperation of a lower guide rail and an upper guide rail which roll horizontally with a conical roller bearing. Two pressure sensors are arranged so as to realize real-time control display of the load and the friction force. In addition, the rotary speed of a shaft to be tested in the test can be automatically and steplessly adjusted; the loading force and the friction force can be automatically adjusted and accurately measured; a shaft sleeve test piece of the device is convenient to detach and the abrasion amount is convenient to measure.

Description

technical field [0001] The invention belongs to the technical field of friction and wear test equipment, which is used for the performance test of shaft and shaft sleeve wear and friction force in a special gas atmosphere, and in particular relates to a shaft sleeve wear test device in a special gas atmosphere. Background technique [0002] Most of the mechanical equipment works in the atmospheric environment. Due to the high oxygen content in the atmosphere, oxide film is easy to form on the surface of the friction pair. The oxide film plays a certain role in protecting the friction pair during the friction and wear process. In a special gas atmosphere environment, the oxygen content is very small, and it is difficult to form an oxide film on the surface of the friction pair. At this time, the friction state of the friction pair is very different from that in the atmosphere. [0003] In actual production, such as the control system of high-voltage circuit breakers, in order...
