Problems solved by technology

Using this method, there are the following disadvantages: First, the oil storage tank is small, adding grease or oil is more frequent, and the workload is relatively large; Small; Third, it is impossible to know whether the lubricating oil in the oil storage tank has been used up. If the lubricating oil has been used but not added, there is still the problem of easy wear

Abstract

The invention provides a wear-resisting bearing bush. The wear-resisting bearing bush comprises a bearing bush body 1 and an oil injection hole 2, wherein a strip-shaped oil storage groove 3 is formed in an inner wall of the bearing bush body 1 in the axial direction; the oil injection hole 2 is communicated with the oil storage groove 3 through an oil inlet pipe 4; a solenoid valve is arranged on a side wall of the oil storage groove 3; an outlet end of the solenoid valve is connected with an oil outlet connector 5; the oil outlet connector 5 is connected with a plurality of oil outlet pipes 6; the oil outlet pipes 6 are connected with corresponding nozzles 7. The strip-shaped oil storage groove 3 is adopted so that an oil storage space is enlarged, and the acting area of lubricating oil can be enlarged in a manner of spraying by the nozzles 7, so that the bearing bush has a better wear-resisting effect. The circulation flow and speed of the lubricating oil in the oil outlet pipes 6 are controlled through the solenoid valve so that resources can be saved and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of bearing sleeves, in particular to a wear-resistant bearing sleeve. Background technique [0002] Bearing is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. The quality of the bearing sleeve is very important for the bearing. Most of the existing ordinary bearing sleeves are simple sleeve-type structures, which are easy to manufacture and low in production cost. However, their service life is short and the frictional resistance to the shaft is relatively large. After a long period of use, the inner wall of the bearing sleeve is easily affected by wear. As a result, the stability of the shaft rod installed therein decreases, and the shaft rod is prone to vibration during high-speed operation, thereby affecting the normal operation of the equipment and p...
