AI Technical Summary
The existing lubricating oil anti-wear testing machine lacks an oil trough design, which leads to excessive consumption of lubricating oil and affects the stability and accuracy of the test.
A lubricating oil anti-wear testing machine with a floating oil tank was designed. The oil tank is kept at a stable height by a cylindrical block and a spring structure to ensure sufficient supply of lubricating oil. Different load conditions are simulated by a detachable connection between a loading rod and a friction body.
It ensures a continuous supply of lubricating oil and consistent testing conditions, improves the stability of testing and the accuracy of data, and simplifies the replacement process of friction elements.
