Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electric power maintenance tools, in particular to a bearing bush clearance adjustment combination wrench. Background Art
[0002] The bearing is the part where the sliding bearing and the journal contact. It is in the shape of a semi-cylindrical surface in the shape of a tile, very smooth, and is generally made of wear-resistant materials such as bronze and anti-friction alloys. In special cases, it can be made of wood, engineering plastics or rubber. There are two types of bearings: integral and split. The integral bearing is usually called a sleeve. There are two types of integral bearings: with or without oil grooves. The bearing and the journal are matched with clearance and generally do not rotate with the shaft. At present, during the maintenance of the unit, the method of adjusting the bearing clearance is: after determining the bearing clearance with a feeler gauge, one person uses a sledgehammer to tighten the anti-weight bolt nut, while the other person uses a wrench to hold the square head of the anti-weight bolt to prevent the anti-weight bolt from rotating with the nut to fix the bearing clearance. Generally, it takes about 25 minutes to accurately adjust the bearing clearance, and at least 2 people are required.
[0003] However, when adjusting the upper and lower guide bearings, the working space is very small and the lighting is poor. In a small space with poor lighting, more than two people use a sledgehammer to tighten the bearings, which poses a high safety risk, makes the workers easily fatigued, and reduces work efficiency. In addition, because the strength of the person using the wrench is far less than the hammering force of the sledgehammer, the bolts often rotate, resulting in a high rework rate and extended working time. Therefore, it is necessary to design and transform the existing bearing adjustment method to solve the problems of low work efficiency and high rework rate. Utility Model Content
