Tutorial On Replacing Bearing Of Jaw Crusher

Jaw Crusher is generally installed above the concrete foundation

. Given the weight of a larger crusher, poor working conditions, and the machine in operation again with great force of inertia to promote the foundation and the machine phylogenetic vibration. Based on vibration are directly caused by other machinery and equipment and building structures vibration. Therefore, the basis of crusher must be separated with the plant base. Meanwhile, in order to reduce vibration, the crusher is placed between the foundation and frame pad rubber or timber. The bearing of general large jaw crusher mainly uses the open sliding bearing. The bearing liner is mostly made of Babbitt alloy, the scraping technical of this kind of bearing has a higher requirements. If the scraping is not good or gap adjusted improperly, there can cause burning watt accident. In process of replacing the bearing of large jaw crusher, we should pay attention to the following points: 1, what should we do when remove the old watt of jaw crusher: (1) Measure the thickness of the old bush joint surface gasket. (2) Measure the levelness of the spindle. (3) Examine whether the spindle is smooth or not, and whether it with the defects of rust, bumps and so on or not. If the situation is exist, you should to eliminate it. (4) Measure the of the bottom clearance, backlash and end clearance of the bearing bush. 2, Testing of the contact of the watt-back with the bearing of the jaw crusher. In order to prevent happening of the reverse sliding and rotating between the bearing bush and the bearing pedestal when the equipment operation, it generally adopts the pin, sleeve positioning mode. 3, The techniques requiring of the scraping the bearing bush Spindle scraping should meet the required standards of technical. 4, Scraping and grinding the spindle bush The scraping is generally divided into rough scraping, fine scraping and refined scraping three processes. 5, The measurement and the adjusting method of the bearing clearance. Reasonable adjust bearing clearance is an important issue, it must meet specified standards The general adjusting methods include: top clearance adjusting and measuring methods, side gap adjusting and measuring methods, the axial clearance measuring method. In operation, you should take regular inspection, through the see, hear, touch ways such as broken mine machine parts observation status and bearing temperature, bearing temperature cannot exceed 60 high temperature, and if I found bearing don"t stop immediately, take increase the amount of oil, the forced ventilation cooling, stay bearing, such as temperature drop before stopping, check and remove the faults.The article is provided by Hongxing company,As the professional manufacturer of complete sets of mining machineryChina cement mills, Henan Hongxing is always doing the best in products and service.Cone crushers:http://www.crusher-machine.com/4.html Impact crusher:http://www.crusher-machine.com/2.html
