Abstract

The invention relates to a small-displacement reciprocating rolling friction abrasion test device. A plane sample clamp is fixedly connected below a cross beam of a hydraulic friction test machine by a tangential force sensor; a rolling sample clamp is positioned at the right side of the plane sample clamp and is fixed on a vertical column of a support frame; a bottom plate of the clamp support frame is connected on a hydraulic piston of the hydraulic friction test machine; the right side of the clamp support frame is provided with a normal force; a screw at the right side of the normal force sensor is connected on a support nut by threads, and the end part of the screw is connected with a rotating disc; the support nut is fixed on a work platform surface of the hydraulic friction test machine by a support seat; and a U-shaped connecting piece at the left side of the normal force sensor is sheathed on the vertical column of the clamp support frame. The small-displacement reciprocating rolling friction abrasion test device can simulate the friction abrasion between a plane sample and a rolling body more really and reliably, is convenient to microscopically analyze the test result, and has high degree of automation, simple and convenient operation, high accuracy of control and test and good repeatability of test data.

Description

technical field [0001] The invention relates to a friction and wear test device, in particular to a rolling friction and wear test device. Background technique [0002] Rolling has been widely used in mechanical engineering due to its characteristics such as low friction. When the rolling body undergoes rolling motion, due to the influence of various factors such as geometric track, ramp, braking and transmission (traction), and deformation of the rotating body, the rolling is often in a restricted rolling state, and there is a sliding phenomenon between the contact interfaces. There are usually stick and slip zones within the contact zone. When the sticky area occupies the entire contact area, the object only rolls without sliding; when the friction of the rolling body increases due to traction or braking, the sticky area in the contact area will continue to decrease, and the object rolls and slides at this time Motion; if the sliding area occupies the entire contact area...
