Utility model content
The purpose of this utility model is to provide a kind of usability of shaft sleeve sliding bearing when rectilinear motion and device in serviceable life tested.
In order to reach above-mentioned requirements and object, the technical solution of the utility model is: it includes L shaped frame, it is characterized in that being fixed with test stand in frame, in test stand, be shaped with open slot, in open slot, card has axle bed, on axle bed, be shaped with axle bed hole, in axle bed hole, supply to install tested axle sleeve, on the axle bed in paraxial seat hole, be provided with for the thermometer hole that inserts temperature sensor, on the test stand at two ends, axle bed hole, be provided with through hole, test axle is installed in through hole, test axle is through through hole and axle bed hole, one end of test axle is connected with and makes to test the mobile device that axle axially moves around through pulling force sensor, on the side of axle bed, be provided with to the boosting mechanism of axle bed middle part pressurization, the pressure of described boosting mechanism is perpendicular to the axial line in axle bed hole, axle bed both sides on test axle are provided with two rotation gear wheels that withstand boosting mechanism pressurization.
Described test axle is for being arranged vertically or horizontally disposed.
The test axle surface that described test axle contacts with rotation gear wheel is plane, and the outer rim of gear wheel is the face of cylinder.
Described gear wheel is fixed on test stand through wheel shaft.
Described mobile device is the drift of punch press.
The boosting-rod of described boosting mechanism is the piston rod in hydraulic jack.
According to the shaft sleeve sliding bearing rectilinear motion frictional wear test device of said structure design, in use, first detect the wall thickness of tested axle sleeve, again tested axle sleeve is pressed in axle bed hole, and put into together the open slot of test stand, insert test axle, test axle is connected with the mobile device of tensile force of belt sensor, two are rotated gear wheel and test is coupling tactile, the boosting-rod of boosting mechanism withstands axle bed, in thermometer hole, insert temperature sensor, start mobile device and boosting mechanism, and the translational speed of adjustment needs, the pulling force of test axle upper pulling force sensor, the pressure of boosting mechanism, start test, record is because the temperature rise that test axle sleeve and the sliding friction to axial of testing axle cause changes, after reaching experimental period, in axle bed hole, take out tested axle sleeve, again measure tested axle sleeve and the wall thickness of testing on axle surface of contact, obtain the wear extent of this axle sleeve rectilinear motion friction, estimate serviceable life, the correlated performances such as temperature rise.This test unit can be simulated the straight-line various operating modes of shaft sleeve sliding bearing completely, obtain direct, reliable test figure, for design and the application of shaft sleeve sliding bearing provides assessable foundation, solved that people wish to solve always and the technical matters that do not solved.
