First, a brief introduction to the project

MMUD-B improved test machine, which mainly realizes sliding friction of end face and pin, and can also extend other friction pairs according to the interface of spindle and lower support plate, and can be used at room temperature or high temperature and change lubrication state (no oil lubrication or oil soaking lubrication), load, speed, friction spousal material, friction pair surface roughness, hardness and so on. Under various parameters, a high test force is applied to the pair of friction pairs to test the friction properties of the materials, powder metallurgy, alloy bearings and other materials under different conditions. It can be used to study the wear resistance of the pairs of pairs of friction pairs and materials.

It can be used for rolling, sliding or sliding rolling compound movement under certain contact pressure. It has a stepless speed regulation system and can be used to evaluate the friction and wear properties of lubricants, metals, plastics, coatings, rubber and ceramics at very low speed or high speed, such as low speed pin. With large plate and small plate, single needle and three needle) friction function, four ball long anti wear performance and four ball rolling contact fatigue, ball - Bronze three lubrication properties, and the test of thrust washer, ball to disc, mud wear, rubber seal ring lip seal moment and stick slip friction performance, high temperature end face has already been in major research institutes It is widely used. This type of testing machine has a wide application in the field of tribology, petrochemical, mechanical, energy, metallurgy, aerospace, colleges and universities, research institutes and other departments.

Two. Main functions and characteristics:

The test force is controlled by a closed loop servo system. The test force is stable and reliable. The test force can be set by the operator on the computer interface. The parameters of the spindle speed, rotation, test force, friction torque, friction pair temperature and test time are controlled by the computer, and the test number can be collected in real time. According to the test curve, the test data and curves can be stored, accessed, printed and output. The spindle motor uses the imported AC servo integrated speed control system and the motor. The spindle and the upper part of the motor are equipped with the driven and active specially made circular arc tooth pulley, the driven pulley is designed to resist torsion, and the power of the motor is transferred to the main shaft through the arc tooth synchronous belt. Because of the application of closed loop speed regulation system, it is high at low speed. The transmission torque has completely changed the characteristics of the thyristor continuously variable transmission system at a low speed.
