【 Jiaxing bearing manufacturer column 】 Jiaxing bearing damage cause analysis and countermeasures

There is rotational, have HRB bearing ( ) 【 Jiaxing bearing manufacturer column 】 Jiaxing bearing damage cause analysis and countermeasures. Jiaxing bearing group sales co. , LTD. ( The company) Is jiaxing bearing factory set up in the spot sales window, specializing in HRB brand bearings, existing stocks of 50 million yuan, covers the whole bearing, have very strong cash supply ability. Jiaxing bearing damage cause analysis and countermeasures: bearing cannot be directly observed in the operation, but through the noise, vibration, temperature, lubricant, etc can be learned about bearing abnormal condition. The representative of the bearing damage cases; There are crack, crack defect part of the gap. The reasons are as follows: the impact of the host load is too large, spindle and bearing with large amount of interference; Also have larger stripping friction causes the crack; When installation precision is bad; Improper use, With copper hammer, card into the big foreign body) Friction and crack. Action: check the conditions of use, at the same time, set the appropriate interference and check material, improve the installation and use, check the lubricant to prevent friction crack. 2, the raceway surface of the metal strip surface stripping operation. After stripping is obviously concave and convex shape. Bearing roller and reasons both inner and outer ring raceway surface under periodic pulse load, resulting in a cycle change of contact stress. When stress cycles after reaching a certain value, the rolling element bearings, their work within or surface produces fatigue. If the bearing load is too big, can make the fatigue. In addition, the bearing installation is not straight, shaft bending, also can produce the raceway stripping phenomenon. Countermeasures: should be used to study conditions and selection of bearing and clearance, and examine the machining precision of the shaft and bearing box, installation method, lubricants and lubrication. 3, burns bearing heating, and then burn can't rotate. Burns is usually the cause of insufficient lubrication, the quality of lubricating oil is not in conformity with the requirements or metamorphism, and bearing assembly too tight. Another clearance is too small and the load is too large, Preloading) Roller deflection. Countermeasures: select the appropriate clearance ( Or increase the clearance) To check the kinds of lubricant, ensure injection, check the conditions of use, in case the positioning error, improve the bearing assembly method. 4, maintains a looseness or breakage fracture rivet, roller broken. Its reasons: excessive torque load, lubrication, the speed change frequently, big vibration, bearing in the condition of inclined installation, card into the foreign body. Countermeasures: according to the using conditions and lubrication condition to find whether appropriate, pay attention to the use of the bearing, studies the selection of the cage are appropriate and rigidity of bearing box are load requirements. 5, creep inside or outside surface skid, mirror or discoloration, sometimes get stuck. Reasons are as follows: insufficient interference fit place, and tighten enough sleeve, abnormal temperature, excessive load on the host. Countermeasures: to study the interference amount whether appropriate, check the conditions of use, check the shaft and the precision of the bearing housing. Part or all of 6, rust corrosion rust, rolling body direction of stripe rust. The reasons are as follows: bad condition of storage, improper packing, anti-rust agent, such as acid solvent, water bearing directly with the hand. Countermeasures: to prevent rust in custody, regular oil packing not regularly, strengthen the sealing performance, regularly check the oil, the oil is not qualified or bad to change in time, to correct the use of the bearing. 24-hour customer service hotline: if you are interested in the above jiaxing bearing factory introduction industry information or have any questions, please click on contact us page on the right side of the online customer service, or call:, you close the way of jiaxing bearing purchasing advisors. - - - - - - Editor: jiaxing bearing factory HRB bearing sourcing consultant LTD.
