In the moving parts, the parts are worn due to long-term friction. When the clearance between the shaft and the hole wears to a certain extent, the parts must be replaced. Therefore, the designer chooses a lower hardness and better wear resistance when designing. The material is a shaft sleeve or a bushing, which can reduce the wear of the shaft and the seat. When the shaft sleeve or the bushing is worn to a certain extent, it can be replaced. This can save the cost of replacing the shaft or the seat. Generally, the bushing and the seat are used. Interference fit, and clearance fit with the shaft, because wear is unavoidable in any case, can only extend the life, and shaft parts are relatively easy to process; some new designers do not like this design, think that It is an increase in cost during manufacture, but after a period of use, it is still necessary to modify it in accordance with this method. However, the modification is likely to reduce the accuracy of the equipment. The reason is simple. Secondary processing cannot guarantee the position of the center of the seat hole.   In addition, the bushing is used to replace rolling bearings (such as camshafts) in places with low speed, high radial load and high clearance requirements (actually, the bushing is also considered as a plain bearing). The material requires low hardness and resistance Grinding, the inner hole of the shaft sleeve can be ground and scraped to achieve high matching accuracy. There must be an oil groove on the inner wall. Lubrication of the shaft sleeve is very important. If dry grinding, the shaft and shaft sleeve will be scrapped quickly. Recommended here Scrap the inner hole wall of the sleeve during installation, which can leave many small pits and enhance lubrication   1. Plain bearing bushing generally function as sliding bearings. In order to save material, the wall thickness of the sleeve is designed according to the axial load required by the bearing. Generally, cast copper and bearing alloy materials are used. The shaft sleeve is divided into open and non-open, which depends on the needs of the structure. Generally, the sleeve cannot bear axial load, or can only bear small axial load. Or add thrust bearings. The shaft is generally round.   2.Bushings generally function as linings. The shaft can be of various shapes, as is the bushing. Bushings can be used to prevent corrosion, eliminate assembly gaps, etc.   The shaft sleeve generally plays the role of axial positioning, and the end is in contact with the gear bearing and other parts under compressive stress. Sometimes the shaft must be matched with seals and other standard parts, and it is necessary to ensure that the middle part can pass through the shaft end. The shaft sleeve and seal ring can be made thin to ensure that the parts pass through.   Plain bearing bushing have different uses in different occasions, can be axially positioned, can reduce friction and vibration, and can also ...

Flange (tool part) Flange (Flange), also known as flange flange or flange. The flange is a part that connects the shaft and the shaft, and is used for the connection between the pipe ends. It is also used in the equipment inlet and outlet for the connection between two devices, such as the reducer flange. The flange connection or flange joint refers to a detachable connection in which a flange, a gasket and a bolt are connected to each other as a group of combined sealing structures. Pipe flange refers to the flange used for piping in pipeline installations, and used on equipment refers to the inlet and outlet flanges of equipment. There are holes in the flange, and the bolts tightly connect the two flanges. The flanges are sealed with gaskets. Flange is divided into threaded connection (thread connection) flange, welding flange and clip flange. The flanges are used in pairs. Wire joint flanges can be used for low pressure pipelines, and welded flanges can be used for pressures above 4 kg. Add a gasket between the two flanges and tighten with bolts. Different pressure flanges have different thicknesses, and they use different bolts. When pumps and valves are connected to pipelines, the parts of these equipment and equipment are also made into corresponding flange shapes, also known as flange connections. Any connection parts that are bolted at the periphery of two planes and closed at the same time are generally referred to as "flange", such as the connection of ventilation ducts, this type of parts can be called "flange parts". However, this connection is only a part of the equipment, such as the connection between the flange and the water pump, it is difficult to call the water pump a "flange-type part". Relatively small ones, such as valves, can be called "flange parts". Reducer flange, used to connect the motor and the reducer, and the connection between the reducer and other equipment. Flange connection is to fix two pipes, pipe fittings or equipment respectively on a flange plate first, and add flange pads between the two flange plates, and fasten them with bolts to complete the connection. . Some pipe fittings and equipment already have flanges, which are also flange connections. Flange connection is an important connection method for pipeline construction. The flange connection is easy to use and can withstand large pressures. In industrial piping, in the home, the diameter of the pipe is small and the pressure is low, and the flange connection is not visible. If in a boiler room or production site, flanged pipes and equipment are everywhere. [1] According to the connection method, the flange connection types can be divided into: plate type flat welding flange, neck flat welding flange, neck welding flange, socket welding flange, thread flange, flange cover, neck welding ring Loose sleeve flange, flat welding ring loose sleeve flange, ring groove surface flange and flange cover, large diameter flat flange, large diameter high neck flange,...
