Solution to the failure of the jaw crusher bearing



The 颚-type crusher, also known as the PEX jaw crusher, is an upgraded product of the PE jaw crusher. The jaw crusher retains the advantages of PE crusher with large crushing ratio, uniform product size, simple structure, reliable performance and convenient maintenance. It is suitable for coarse and medium-sized crushing and can crush various ores with compressive strength of 2000kg/cm2. , rock materials. The jaw crusher is one of the best equipment for rough crushing in sand and gravel production lines and mining and mineral processing. Long-term high-load operation of the jaw crusher can cause failures in bearings, linings, hammers, and motors. The following is a brief introduction to the causes and countermeasures of excessive bearing temperature during the use of the jaw crusher.

The jaw crusher bearing oil is cut off or the oil is injected too much; the oil hole is blocked and the oil is not added; the flywheel wheel counterweight position is offset, the frame is beating; the bushing is axially tilted; the bearing wears or remains Damage to the frame, etc., may cause the bearing temperature of the jaw crusher to be too high. In response to the above problems, Zhengzhou Xinhai Machinery Liu engineers summarized the corresponding countermeasures: according to the specifications, quantitatively refueling on time; cleaning oil holes and oil sump plugs; adjusting the position of the flywheel counterweight; removing the bearing cap on the frame , tighten the bushing and remove the flywheel or sheave, replace the new adapter bushing; replace the bearing; replace the end cap and the sealing sleeve, or loosen the upper bearing cap of the heating end of the frame bearing housing, with the fuse and The insert cover is pressed into the bearing housing groove, and the bearing cap is fixed to eliminate the rotation of the insert cover. Users of the jaw crusher need to regularly check and repair the equipment to ensure the stable operation of the equipment.

The development and application of the 细-type fine crusher technology, as an engineering technology, is not only related to the theoretical level, science and technology, but also closely related to the 颚-type fine crusher structure, material selection, processing and manufacturing methods and manufacturing processes. Therefore, it is of great economic and practical significance to optimize the design, materials and processing technology of the jaw crusher. Zhengzhou Xinhai Machinery adheres to the development concept of science and technology development and technology strong factory. Xinhai Machinery is at the forefront of scientific and technological innovation in mining machinery industry for the transformation and replacement of sand and gravel production lines and mineral processing equipment.
