What is the difference between bushing forgings and bush forgings

Bushing forgings are used at low speeds instead of rolling bearings:

1 shaft sleeve forgings used in gear shaft or bearing, the main role is to play a fixed and positioning role, such as the gear shaft in the reducer installation needs to be used, used to fix the central positioning of the shaft and bearings do not let it shift because of vibration during operation.

2. The sleeve forgings play the role of sliding bearings. In order to save materials, the wall thickness of the sleeve forgings is designed according to the axial load required by the bearings. Generally choose cast copper and bearing alloy material. Shaft sleeve forgings are open and not open, according to the needs of the structure. General shaft sleeve forgings can not withstand axial load, or can only withstand a small axial load or thrust bearing and the shaft is generally round.

3. The shaft sleeve forgings in some rotational speed is low, high radial load and clearance to demand higher places (such as the camshaft) replacement for rolling bearing (actually shaft sleeve is a kind of sliding bearing), material requirements low hardness and wear resistance, scraping to grind and shaft sleeve forgings inner hole, fit to achieve high accuracy, must have the lubricating oil tank, on the wall bushing lubrication is very important, Some grinding shaft and sleeve forgings will soon be scrapped. It is recommended to scrape the inner hole wall of the sleeve during installation, so that many small pits can be left to enhance lubrication function.

The bushing forgings are used as bearing parts in the friction pair

Bushing forgings are used in mechanical parts, in order to achieve sealing, wear protection, etc. Bushing forgings are widely used. Many parts in the industrial field, such as valves and bearing forgings, will use bushing forgings.

Function of bushing forgings:

The use of bushing forgings is relatively high flexibility, it can play a lot of roles, generally speaking, bushing forgings are a kind of parts to protect equipment. The use of bushing forgings can reduce the wear, vibration and noise of equipment, and has the effect of corrosion prevention. The use of bushing forgings can also facilitate the maintenance of mechanical equipment, simplify the structure of equipment and manufacturing process.

The function of bushing in practical work is closely related to its application environment and purpose. In VALVE APPLICATIONS, BUSHING DEVICES TRAP the STEM IN the BONNET TO reduce leakage and seal THE VALVE. In the application field of bearing forgings, the use of bushing forgings can reduce the wear between bearing forgings and shaft seat forgings, and avoid the increase of clearance between shafts and holes.
