Thrust sliding bearing lubricating property teaching demonstration device

Abstract

The invention relates to a thrust sliding bearing lubricating property teaching demonstration device belonging to the technical field of aided teaching instruments and experimental facilities. The thrust sliding bearing lubricating property teaching demonstration device comprises a support, a loading disc, experimental bearing bushes and an oil cylinder, wherein the oil cylinder and the loading disc are respectively arranged on the support by shafts; the plurality of experimental bearing bushes are arranged in the oil cylinder in circumferential directions; the loading disc is arranged above the experimental bearing bushes; the loading disc and the oil cylinder are coaxially arranged; the loading disc is driven by a motor to rotate; a loading mechanism is arranged on the loading disc; a push plate is arranged outside the oil cylinder; and the support is provided with a dial indicator corresponding to the push plate. By utilizing the thrust sliding bearing lubricating property teaching demonstration device, demonstrative experiment of common plane thrust bearing bush, hydrostatic pressure thrust bearing bush and tilting thrust bearing bush can be carried out, experimental phenomenon is visual, and observation and understanding are convenient.

Description

Technical field: [0001] The invention belongs to the technical field of auxiliary teaching equipment and experimental equipment, and in particular relates to a teaching demonstration device for the lubricating characteristics of a thrust sliding bearing. Background technique: [0002] Sliding bearings are a very important content in mechanical design courses. At present, there are only radial sliding bearing test benches in the teaching of undergraduate mechanical design courses in my country, and there is a lack of thrust sliding bearing test benches. Only radial sliding bearing experiments can be carried out, which is not conducive to students' understanding of sliding bearing knowledge. And there are many types of thrust sliding bearings, which can be divided into hydrodynamic lubrication, hydrostatic lubrication, and ordinary lubrication bearings according to the lubrication state. If the test benches are made separately, the cost is high and it is inconvenient to use. ...

AI Technical Summary

Problems solved by technology

At present, there are only radial sliding bearing test benches in the teaching of undergraduate mechanical design courses in my country, and there is a lack of thrust sliding bearing test benches. Only radial sliding bearing experiments can be carried out, which is not conducive to students' understanding of sliding bearing knowledge.

And there are many types of thrust sliding bearings. According to the lubrication state, they can be divided into hydrodynamic lubrication, hydrostatic lubrication, and ordinary lubrication bearings. If the test benches are made separately, the cost is high and it is inconvenient to use.

Moreover, when the existing bearing test bench measures the experimental parameters such as oil film pressure and friction coefficient, the experimental phenomena are not obvious and intuitive enough.
