Oil film pressure display module based on dynamic pressure bearing teaching

Abstract

The invention discloses an oil film pressure display module based on dynamic pressure bearing teaching.The display module comprises an experimental platform, a motor is mounted on the experimental platform, a motor shaft of the motor is connected with a transmission module, the transmission module is connected with a main shaft, the upper end of the main shaft is connected with a rotating disc key, an oil film pressure display device is arranged on the upper surface of a rotating disc, the oil film pressure display device comprises a wedge-shaped disc and oil pressure display tubes, the upper surface of the rotating disc is in contact with the surface of the wedge-shaped disc, the rotating disc can be rotated, and the wedge-shaped disc can move up and down relative to the rotating disc; the rotating disc and the wedge-shaped disc are arranged in a lubricating oil tank and immersed in lubrication oil; a wedge-shaped gap is formed between the upper surface of the rotating disc and the lower surface of the wedge-shaped disc, a hollow rod is vertically arranged in the center of the upper surface of the wedge-shaped disc, and the lower end of the hollow rod is in close fit with the wedge-shaped disc.By means of the oil film pressure display module, the oil pressure curve can be displayed in a visualized mode, and problems are found and solved in the manual operation process.

Description

technical field [0001] The invention relates to an oil film pressure display module based on dynamic pressure bearing teaching, which belongs to the technical field of teaching aids for dynamic pressure bearings, and in particular to an oil film pressure display module based on dynamic pressure bearing teaching, which can directly display the pressure. Background technique [0002] Dynamic pressure lubricated bearings are widely used in various power transmission systems such as steam turbines, gas turbines, and gearboxes. They can effectively improve mechanical operation due to their characteristics of large load-carrying capacity, low power consumption, good impact resistance, good vibration resistance, and high operating accuracy. efficiency and service life. With the emergence of various high-precision mechanical equipment today, how to reduce the friction between the rotating pairs of each component as much as possible, so as to improve the efficiency of mechanical oper...

AI Technical Summary

Problems solved by technology

Although the precision of the pressure sensor is relatively high, the experimental phenomenon is not obvious enough, which does not provide substantial help to engineering education in colleges and universities, and does not allow students to be familiar with and master the important engineering knowledge of hydrodynamic lubrication.

The patent "A Portable Teaching Aid for Demonstrating the Principle of Fluid Dynamic Pressure" proposes to use a glass tube for display, but this experimental instrument also brings a disadvantage. Because the upper plate is inclined, the distance from the lower plate is inconsistent, that is, the upper plate The force is not uniform, which is bound to have an impact on the experimental phenomenon

Second, the research object: most of the research objects of today's sliding bearing test benches are the radial pressure distribution, and lack the axial pressure for the thrust bearing
