Problems solved by technology

However, this article only theoretically analyzed the performance of electrorheological fluid bearings, and did not give a specific design plan
Moreover, the current electrorheological fluid has not yet met the requirements of engineering applications due to defects in stability, shear strength and operating temperature range.

Embodiment Construction

[0013] The structure of the smart sliding bearing is as follows figure 1 As shown, the coils arranged in the inner sleeve of the bearing can change the magnetic field inside the bearing, thereby adjusting the viscosity of the lubricant and improving the tribological properties. In the design, the bearing inner sleeve is made of metal with certain mechanical strength and magnetic conductivity, such as cast iron and carbon steel; the coil is wound with common enameled wire; Strong rare-earth permanent magnets; the pole pieces are machined from ferromagnetic electric pure iron.

[0014] When the bearing is running, first measure the speed and load of the rotating shaft through an external sensor, and then collect the signal of the sensor to the computer through the data acquisition card, then compare the measured speed and load information with the database in the computer, and output the signal Controls the voltage of the DC power supply. The DC power supply is connected to th...

Abstract

The invention discloses an intelligent sliding bearing capable of adjusting the viscosity of lubricating fluid automatically and a control method thereof, which belong to the technical field of mechanical design and automatic control. The bearing comprises a bearing inner bush (7), a bearing outer bush (3), a coil (4) arranged between the bearing outer bush (3) and the bearing inner bush (7), an external force sensor and a rotation speed sensor, wherein the each of the left and right ends of the bearing inner bush and the bearing outer bush is provided with a pair of pole shoes (1), and an annular magnet (2) is arranged between each pair of pole shoes; and a sealing structure is arranged between the annular magnet (2) and the pole shoes (1) and a rotating shaft (6) and keeps magnetic fluid (5) between the rotating shaft (6) and the bearing inner bush (7). The bearing and the control method thereof can adjust the viscosity of the lubricating fluid automatically according to working conditions, so that the bearing can be kept in a well lubricated state and friction power consumption and wear are reduced.

Description

technical field [0001] The invention relates to an intelligent sliding bearing for automatically adjusting the viscosity of lubricating fluid and a control method thereof, belonging to the technical field of mechanical design and automatic control. Background technique [0002] Sliding bearing is a kind of bearing widely used in the industrial field. It has the advantages of strong bearing capacity, high rotation precision, stable operation, and good cushioning and vibration absorption [Yang Kezhen, Cheng Guangyun. Mechanical Design Fundamentals. Beijing: Higher Education Press, 2003 .]. For plain bearings lubricated by liquids, the viscosity of the lubricating liquid has an important influence on the performance of the bearing. If the viscosity of the lubricating fluid is too low, the bearing capacity of the lubricating oil film will be insufficient, causing direct mechanical contact between the surfaces of parts, increasing friction and wear, and even causing catastrophic...
