Embodiment 1

[0041] First install the rubberized drum 18 into the lower environment chamber 10-3, start the machine now, the driving motor drives the rubberized drum to run idly, and record the torque at this moment by the torque sensor M 1 . Then stop the machine and install the tested test idler roller 17 in the environment chamber 10-2 after weighing, put the dust of the simulated environment in the dust box 9-1 after covering the upper environment chamber, and place the liquid of the required simulated environment Loaded into the atomizer 7, the preparation required for the test is over.

[0042] Further, the loading motor 5 is turned on to apply pressure to the test roller 17 so that the test roller 17 is in close contact with the rubber drum 18 and there is a certain positive pressure. The positive pressure applied by the loading motor 5 can be recorded by the computer or the display device. The values ​​of the side ring pressure sensors are F 1 、F 2 .

Embodiment 2

[0047] The method for carrying out the wear test of the idler roller on the conveyor idler roller friction and wear test bench is characterized in that it comprises the following steps:

[0048] Step 1: Before the test starts, the radius of the lagging roller can be known—— r

[0049] Step 2: Weigh the test roller before the start of the test to obtain the quality of the test roller—— m

[0050]Step 3: Start the machine and get the no-load torque from the torque sensor under the condition of no load—— M 1

[0051] Step 4: Apply load to the test idler roller through the loading part, and obtain the positive pressure between the test idler roller and the rubberized roller from the ring pressure sensors on the left and right sides of the loading screw—— F 1 、F 2

[0052] Step 5: Start up and get the under-load torque from the torque sensor under loading conditions—— M 2

[0053] The coefficient of friction is calculated as follows:

Description

technical field [0001] The invention relates to a friction and wear test bench for conveyor rollers Background technique [0002] The invention relates to the technical field of tribology, in particular to a test bench for real-time measurement of the friction coefficient of idler rollers of an idler conveyor. [0003] Due to its own working characteristics, the idler rollers of the idler conveyor often work under complex working conditions. The friction and wear have complex characteristics, including the wear caused by the friction between the idler roller and the conveyor belt, and the scattered materials mixed in The wear caused by the friction and scoring of the idler roller and the conveyor belt on the idler roller, as well as the chemical corrosion caused by factors such as air in the working environment and corrosive gases and salt in the material, require a complex environmental chamber to Simulate the environment. At the same time, the change of the friction coef...
