Adjustable sliding bearing and adjusting method

Abstract

The invention discloses an adjustable sliding bearing, and relates to the technical field of sliding bearings. The adjustable sliding bearing comprises a bearing seat, a bearing assembly and a rotaryshaft, wherein a through hole is formed in the bearing seat, the bearing assembly is mounted in the through hole, a journal of the rotary shaft is arranged in the bearing assembly, and a lubricating film is arranged between the bearing assembly and the journal of the rotary shaft. The bearing assembly comprises a first sliding bearing, a second sliding bearing and a connecting part. The adjustablesliding bearing further includes at least two expansion sleeves. According to the adjustable sliding bearing, the first sliding bearing and the second sliding bearing are separately arranged on the bearing seat, the situation that when the lower bottom of the first sliding bearing is under pressure from the bottom of the left side of the journal, the bearing seat is not used as a fulcrum to leverthe lower bottom of the second sliding bearing to impact the rotary shaft is facilitated, the inclination of the rotary shaft is increased, and that is, the separation type first sliding bearing andthe second sliding bearing can reduce the impact on the rotary shaft and reduce the damage to the uniform distribution of the thickness of the lubricating film (an oil film, a gas film and the like) compared with an integrated type of sliding bearing.

Description

technical field [0001] The invention relates to the technical field of sliding bearings, in particular to an adjustable sliding bearing. Background technique [0002] Sliding bearings, that is, bearings that work under sliding friction. Under lubricating conditions, the two relative sliding surfaces of the bearing are separated by the lubricating medium without direct contact, which greatly reduces friction loss and surface wear. The formation of the lubricating film (oil film, gas film, etc.) between the journal of the sliding bearing and the bearing is the basic condition for the normal operation of the sliding bearing. The factors that affect the formation of the lubricating film include the lubrication method, the relative motion speed of the kinematic pair, and the physical properties of the lubricant. and the roughness of the moving sub-surface, etc. Sliding bearings work smoothly, reliably, without noise, have large carrying capacity and high rotation precision, and...

AI Technical Summary

Problems solved by technology

[0005] One of the objectives of the present invention is to solve the problem that the sliding bearing in the prior art is caused by the excessive inclination of the journal during work, resulting in the rupture of the lubricating film, resulting in the direct contact between the journal and the bearing and the problem of wear
