Oil way structure of sliding bearing

Abstract

The invention provides an oil way structure of a sliding bearing. The oil way structure comprises a cooling device, and a thrust head, a thrust pad and a pressing plate which sleeve the outer side ofa rotating shaft. The thrust head comprises a big head end and a small head end which are integrally connected. The two end faces of the big head end are connected with the thrust pad and the pressingplate correspondingly. A first gap is formed between the big head end and the thrust pad. A second gap is formed between the big head end and the pressing plate. The cooling device is located in an oil tank which contains lubricating oil. The cooling device comprises an outer partition plate and a plurality of cooling pipes. A space with an inlet and outlet is defined by the outer partition plate. The inlet and outlet communicates with the oil tank. A plurality of cooling pipes are located in the space defined by the outer partition plate. One end of the first gap and one end of the second gap both communicate with the space defined by the outer partition plate. The other end of the first gap and the other end of the second gap both communicate with the oil tank through a channel formed in the bearing. Two planar viscous pumps are formed to provide driving force; and the heat transferring efficiency of a cooler is improved, and the cooling effect of the bearing is improved.

Description

technical field [0001] The invention relates to the technical field of lubrication and cooling of sliding bearings, in particular to the oil passage structure of sliding bearings. Background technique [0002] When the existing sliding bearing self-lubricating oil supply, many use the centrifugal force of the through hole on the rotary thrust head immersed in the oil pool to supply oil, or the rotating shaft is driven by an impeller pump or a gear pump to provide power. The cooling efficiency of the lubricating oil in the above manner is low and the structure is not compact. Such as figure 1 As shown, the sliding bearing includes a guide seat 3, a thrust head 1, a thrust shoe 7 and a guide shoe 2, the thrust shoe 7 and the guide shoe 2 are located in the guide seat 3, one end of the thrust head 1 is located in the guide seat 3, and the other end Located outside the guide seat 3 , the end face of the thrust head 1 is in contact with the thrust shoe 2 , and the guide shoe 2 ...

AI Technical Summary

Problems solved by technology

The heat transfer efficiency of the heat conduction heat transfer method is low, resulting in a large volume of the oil pool 1 and the oil-water cooler 9 required
