Abstract
The utility model relates to an end face friction testing device, which is characterized in that a friction member which forms a plane surface is fixed on the end face of a rotating shaft, and is in close contact with a sample on a work bench arranged on a hydraulic loading device, a sensor of a thermometer for computers is connected with the sample, and a sensor of a torque meter for computers is connected with the work bench. The utility model overcomes error message resulted from the situation that a friction reducing wear resistant layer wears out caused by that a friction member in the prior art is a cylindrical surface, and also overcomes the pressure errors of a tension spring, a balance block and the structure of a scale in the prior art.
Description
Affiliated technical field
The utility model relates to a kind of friction test device.In International Patent Classification (IPC), belong to by means of the chemistry of measuring material or physical property is tested or the analysis of material group.End-face friction test unit particularly.
Background technology
Frictional testing machine is used for the known M2000 of having of end-face friction.It is made of engine, gearing, lever pressure-loaded device, worktable and anchor clamps, pen recorder, etc.The mill part is installed in the rotating shaft, utilizes its face of cylinder and sample to do the line contact friction.Said sample is fixed on the pressure-loaded device, and is positioned at the top to the mill part.Pressure relies on extension spring, counterbalance weight and fulcrum shaft to produce, and estimates reading on the metering scale.The rotating speed of this device is fixed as 0.4m/s.Friction factor obtains by calculating.Can't measure the finishing temperature of sample in addition.
When above-mentioned test unit is used to measure the rubbing wear of three layers of composite bearing sheet material, because only several micron thickness of anti-friction wear-resistant layer, test promptly forms the concave cylindrical face soon, arrived the middle layer of sample this moment, it is the copper powder layer, therefore the friction factor that records is not the friction factor of anti-friction wear-resistant layer, but the friction factor of copper powder layer can not embody the friction and wear behavior that sheet material rolls into the bearing of sleeve-like.
The utility model content
The purpose of this utility model provides the frictional wear test device of a kind of contact, overcomes in the prior art test to cause cylindrical concave and the difficult problem of the information that leads to errors.
It is as follows to disclose new technical scheme:
A kind of end-face friction test unit comprises engine, gearing, pressure-loaded device, worktable and anchor clamps and registering instrument at least, it is characterized in that being plane the mill part is connected and fixed on the end face of rotation axis, and be installed on hydraulic loading device on worktable on sample closely contact.
According to the model machine that such scheme is made, avoided the pressure error of prior art extension spring, scale, particularly be the plane to the mill part, contact as face with sample, so overcome the worn out anti-friction wear-resistant layer of prior art and wear the difficult problem of error message.Owing to adopted hydraulic loading device, extension spring, counterbalance weight, shortcoming that the scale device error is big have been overcome.
