Is there any difference between sleeve forgings and bushing forgings? Many people have expressed doubts, so the following article will mainly explain it to everyone.

Shaft sleeve forgings are used to replace rolling bearings at low speeds:

1. Shaft sleeve forgings are used on gear shafts or bearings, mainly for fixing and positioning purposes. For example, gear shafts need to be used during the installation of reducers to fix the center positioning of the shaft and prevent the bearings from shifting due to vibration during operation.

2. The shaft sleeve forging serves as a sliding bearing, and in order to save materials, the wall thickness of the shaft sleeve forging is designed according to the axial load required by the bearing. Generally, cast copper and bearing alloy materials are selected. Shaft sleeve forgings can be divided into open and non open types, depending on the structural requirements. Generally, shaft sleeve forgings cannot withstand axial loads, or can only withstand small axial loads or thrust bearings, while shafts are generally circular.

3. Shaft sleeve forgings are used to replace rolling bearings (in fact, shaft sleeves are also a type of sliding bearing) in places with low rotational speed, high radial load, and high clearance requirements (such as camshafts). The material requirements are low hardness and wear resistance. The inner hole of the shaft sleeve forging is ground and scraped to achieve high fitting accuracy. There must be a lubricating oil groove on the inner wall. Lubrication of the shaft sleeve is very important. Several grinding shafts and shaft sleeve forgings will soon be scrapped. It is recommended to scrape the inner hole wall of the shaft sleeve during installation, which can leave many small pits and enhance lubrication function.

The application of liner forgings in friction pairs as wear-resistant components

Sleeve forgings are matching parts used for mechanical components to achieve sealing, wear protection, and other functions. The application range of bushing forgings is very wide, and many components in the industrial field, such as valves, bearing forgings, etc., will use bushing forgings.

The function of lining forgings:

The flexibility of using liner forgings is relatively high, and they can play many roles. Generally speaking, liner forgings are a type of component that protects equipment. The use of lining forgings can reduce equipment wear, vibration, and noise, and have anti-corrosion effects. The use of lining forgings can also facilitate the maintenance of mechanical equipment, simplify the structure and manufacturing process of equipment.

The role of the liner in practical work is closely related to its application environment and purpose. In the field of valve applications, a liner is installed inside the valve cover to cover the valve stem, thereby reducing valve leakage and achieving a sealing effect. In the application field of bearing forgings, the use of liner forgings can reduce wear between bearing forgings and shaft seat forgings, and avoid increasing the gap between the shaft and the hole.
