Bearing Working Condition
- Jun 02, 2017 -

The bearing pad is a sliding bearing and shaft contact part, very smooth, generally made of bronze, friction-reducing alloy and other wear-resistant materials, in special circumstances, Bush Bearing can be made of wood, plastic or rubber. Also known as "bushing", the shape of the tile-like semi-cylindrical surface.

Sliding bearing work, between the bearing pad and the shaft requires a thin layer of oil film from the lubrication effect. If there is a direct friction between the bearing pad and the shaft due to poor lubrication, the friction will produce a very high temperature. Although the bearing pad is made of a special high temperature resistant alloy material, the high temperature generated by direct friction is still sufficient Bad. Bush Bearing Bearings may also be due to the load is too large, the temperature is too high, there are impurities in lubricants or viscosity abnormalities and other factors caused by burning tile. After the burning of the sliding bearing on the damaged.

The so-called scratch pad, that is, after the tires of the tires and the assembly of the shaft Shouban research (axis to be coated with toner), with a scraper scratched on the tile attached to the pink, Bush Bearing with the research with scraping, until the tile Attached to the area of more than 85% of the whole tile surface, complete scratch.

Bearing pad can be cast, in order to improve the friction performance, can be poured in the inner surface of a bearing pad bearing (known as the bearing lining). In order to make the bearing alloy and bearing attached to the well, often in the inner surface of the bearing on the various forms of tenon, groove or thread. Bush Bearing Thin-walled bushings can be bimetallic continuous rolling process and other large-scale production.

Powder metallurgy is the powder of iron or copper and other basic materials mixed with graphite, and then pressed sintering forming. The pores can be stored lubricants, said oil bearing.

The bearing material is usually softer, the inner cylindrical surface should not be processed by grinding, can be boring, King Kong boring, scraping or grinding processing. Grinding should not be used with the shaft diameter with the method of research, but should use a special size and size of the same hole diameter rod. Scraping for part of the tile bearing, scraping with a wide blade scraper. Hand scrape, scratches should be shallow. Bush Bearing The inner surface of the complex shape of the bearing, should be based on the specific shape of the use of special boring method.

The presence of the inserts on the tiles is the micro-tank of the tiles that store the lubricating oil.

Bushing - A part that supports a journal, usually made of bronze, with a bushing inside.

The shaft is supported by the bearing part called the journal, and the part that matches the journal is called the bearing. The friction-reducing material layer cast on its inner surface in order to improve the frictional properties of the pad surface is called a bearing lining. Bush Bearing The material of the bearing pad and the bearing lining is collectively referred to as a sliding bearing material. Commonly used sliding bearing materials are bearing alloy (also known as Babbit or white alloy), wear-resistant cast iron, copper and aluminum alloy, powder metallurgy materials, plastic, rubber, hardwood and carbon-graphite, polytetrafluoroethylene ), Modified polyoxymethylene (POM), and the like.
