Is there any difference between bushing forgings and shaft sleeve forgings? Many people expressed doubts, so the following article mainly tells you.
Shaft sleeve forgings shall be used in low speed instead of rolling bearings:
1. The shaft sleeve forging is used on the gear shaft or bearing, which is mainly used for fixing andpositioning. For example, the gear shaft needs to be used when the reducer is installed to fix the center positioning of the shaft and the bearing so that it will not be displaced due to vibration during operation.
2. The shaft sleeve forging plays the role of sliding bearing. In order to save materials, the wall thickness of the shaft sleeve forging is designed according to the axial load required by the bearing. Cast copper and bearing alloy are generally used. Shaft sleeve forgings can be divided into open and non open according to the needs of the structure. Generally, shaft sleeve forgings can not bear axial load, or can only bear small axial load or thrust bearing, while the shaft is generally round.
3. The shaft sleeve forging is used to replace the rolling bearing (in fact, the shaft sleeve is also a sliding bearing) in some places with low speed, high radial load and high clearance requirements (such as camshaft). The material requires low hardness and wear resistance. The inner hole of the shaft sleeve forging can achieve high matching accuracy after grinding and scraping. There must be an oil groove of lubricating oil on the inner wall. The lubrication of the shaft sleeve is very important, Several grinding shafts and shaft sleeve forgings will be scrapped soon. It is recommended to scrape the inner hole wall of the shaft sleeve during installation, so as to leave many small pits and enhance the lubrication function.
Bushing forgings are used as wear parts in friction pairs
Bushing forgings are used outside mechanical parts to achieve sealing, wear protection and other functions. Bushing forgings are widely used. Bushing forgings are used in many parts in the industrial field, such as valves, bearing forgings and so on.
Function of bushing forging
Bushing forgings have high flexibility and can play many 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 anti-corrosion. The use of bushing forgings can also facilitate the maintenance of mechanical equipment and simplify the structure and manufacturing process of equipment.
The function of bushing in practical work is closely related to its application environment and purpose. In the field of valve application, the bushing is installed in the valve cover to cover the valve stem, so as to reduce the leakage of the valve and achieve the sealing effect. 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 shaft and hole.
