Oiling Lubricant Split Bushing Mechanical Parts Tin Bearing Bronze Bush

Product description

The sliding bearing has the advantages of simple structure, convenient manufacture, long service life, bearing heavy load, stable operation, etc. Therefore, it is widely used as the spindle bearing of machine tools and the crankshaft bearing of large forging equipment. Sliding bearing is also called bearing bush. Its materials are mainly cast iron, wear-resistant cast iron, brass and bronze alloy. The following describes the repair method of copper bearing bush.

Common faults of copper bearing bush

The copper bearing bush is used to support the rotating parts and transmit the generated load to the body of the equipment. The working condition of the bearing bush not only directly affects the machining accuracy of the equipment, but also affects its service life and efficiency. Common faults of copper bearing bush cause wear during long-term use, excessive aging between bearing bush and shaft, uneven contact surface, resulting in deformation of bearing bush. Due to poor lubrication or poor oil quality, oil film cannot be formed between shaft and bearing bush, resulting in dry friction, resulting in "locking" or "burning" lubricating grease of bearing bush is not clean, containing metal or impurities, Mechanical damage or damage caused by improper assembly of bearing bush, such as groove

The most common repair method for copper bearing bush is to replace the bearing bush when removing the equipment fault caused by the bearing bush. This may be suitable for small bearing pads, but it is not economical to replace large diameter bearing pads, and the maintenance time is long. Combined with the actual situation of our factory, this paper introduces the methods of repairing children. Press riveting copper sleeve method. Press a suitable copper sleeve into the bearing bush, and then rivet it. The repair method is to turn the inner hole according to the maximum size of the damaged bearing bush. If there is a certain thickness of the bearing bush after the defect is turned away, the copper sleeve can be selected (to prevent the deformation of the bearing bush, the mould can be made in advance when turning the inner hole). If there is no suitable copper sleeve, it is made of copper alloy plate. After rolling, it is calibrated and welded, and the inner and outer circles of the copper sleeve are machined
