Abstract

The invention discloses a reciprocating type friction wear testing machine with a lubricating and complex force loading system and belongs to the field of design of the friction test machines; the reciprocating type friction wear testing machine comprises a lubricating system, a base support leg, a base, an upper test piece, a heating device, a guide rod I, a lower test piece, a flexible beam, a complex force loading system, a balance weight rod, a balance weight, a rotating shaft, a strain gauge, an L-shaped support, a temperature sensor, a speed regulation motor, a guide rod II, a connectingrod, a crank disc, a speed sensor, a conversion joint and the like. The complex force loading system is arranged on the flexible beam and the L-shaped support, and is composed of a lever weight loading device and a bolt spring loading device; the flexible beam is in threaded connection with the upper test piece, and the upper test piece is connected with the lower test piece through a movable pair, and the friction force is measured through deformation of the flexible beam; and the lubricating system is connected with the inner channel of the upper test piece through a pipeline. According tothe testing machine, large load, high precision loading and friction pair real-time self-lubrication can be realized, and the reciprocating friction performance test of friction pairs in various formscan be achieved.

Description

technical field

[0001] The invention relates to the technical field of friction and wear and lubrication performance testing of materials, and more specifically relates to a reciprocating friction and wear testing machine with its own lubrication and composite force loading system. Background technique

[0002] Reciprocating friction and wear testing machine is a kind of equipment that can be used to test the friction performance of metal or non-metallic material moving pair and the test of lubricant lubrication effect. At present, most of the reciprocating friction and wear testing machines on the market simulate the friction and wear conditions under the condition of dry friction of the test piece. However, in actual working conditions, the friction parts will involve lubrication problems. Most testing machines cannot simulate the lubrication and wear conditions, and the market Most of the reciprocating friction and wear testing machines above have the problem of small loa...
