The correct lubrication method of bearing lubrication grease

2020 - the correct bearing lubrication grease lubrication method 01 - 04 in the process of operation, once the loss and failure, grease, raceway and roller cage will be direct metal to metal contact, bearing will soon be damaged because of dry grinding heat. So how to do quantitative lubrication, bearing on a regular basis to the normal operation of a complete set of machine has important significance. Rolling bearings need at any time to add grease to swap out already metamorphism, seepage and grease contamination. Due to the operation conditions of rolling bearing is protean, all kinds of working condition of equipment operation situation is different, so you need to understand the scene technical professionals to determine the appropriate add grease, time interval according to the bearing equipment running situation from once a day to once a year. Grease add frequency because there are many influence factors in frequency of adding grease, no specific fixed time measure standard. In general, the smaller the bearing, speed faster, lower grease to add frequency. Specifications, the greater the speed of the slower add grease bearing requires more frequent. Main factors are as follows: different types of bearing require different fatliquoring frequency: radial ball bearings cylindrical roller bearing = = basic frequency basic frequency of 5 times the basic frequency of the roller bearing = 10 times the operating temperature of high temperature improves the speed the oxidation of the grease, over 65 & deg; When C rise every 10 & deg; C, double the oxidation rate of the grease. For example, a bearing in 120 & deg; C; With a 65 bearing & deg; C compared to running, the former add grease frequency is usually the latter 10 times. In addition, with the rise of temperature, began to soften grease, and may become fluid and leak from the bearing box, high temperature operation demand a higher frequency of adding grease. Environmental conditions: if bearing in environmental pollution, also need to improve the fatliquoring frequency. Ensure that the lubrication report any abnormal situation, such as: bearing high temperature, noise, vibration or leakage. Add lubricating oil flushing interval many rolling bearings require washing intervals to add a small amount of grease in the grease. Had better use the low pressure oil to add grease gun. If the seal in good condition, should reduce grease injection rate and injection frequency. 1) Check lubricating grease in the bearing stock, demolition, fittings or grease drain plug, check whether there is excess grease outflow. 2) To check whether there is too much bearing and seal leakage. 3) Every time the fatliquoring several injection quantity is enough. Forbidden to add too much grease! Wash on grease grease, recommend the following 'relief' method for pipe fittings and discharge of oil bearing hole: 1) Demolition of the lower drain plug clearing hardening of grease. 2) Wipe grease fittings. 3) Will pumping grease fitting until all the old grease replacement out, new grease. Under the condition of guarantee safe and feasible, to perform this task is best able to run the machine at the same time. 4) In the demolition of the drain plug at the same time, allows the machine to run operating temperatures. That can make the grease evenly distributed and redundant grease by the oil discharge orifice. When bearing box at normal pressure, About 10 - 30 minutes) , it will stop discharge excess grease. Clean and replace oil drain plug for equipped with fittings but no discharge of oil bearing hole: 1) Under the condition of safety, equipment run at operating temperature of the demolition of pipe fittings at the same time, to ensure that the discharge within bearing all excess grease. 2) Clean and replace pipe fittings. A small amount of grease pump into the bearing so as to avoid grease seal instability. 3) Demolition of pipe fittings and allow the equipment in its operating temperature for a few minutes to drain excess grease. If there is no discharge grease, bearing is likely to be very dry, you will need to repeat steps 2 and 3 until the excess grease from. 4) Replace the grease fitting. In type equipped with pressure relief pipe but no discharge of oil bearing hole: 1) Cleaning pipe and pumping grease into bearing until grease from reduced pressure pipe flow. 2) If after the injection of a large amount of grease, grease still not flowed from reduced pressure pipe fittings, the pressure-relief slots may be blocked. Demolition of the reduced pressure pipe fittings and cleaning the reduced pressure tank and replace the new tube. Upon the completion of the pipe to clean or replace, repeat step 1. 3) At operating temperature operation equipment and check whether there is reduced pressure pipe fittings in excess grease. Preventive measures to ensure clean all excess grease and dirt from the bearing and the surrounding. On the outer surface of excess grease and dirt have heat preservation effect and prevent heat dissipation. In addition, the external surface of the equipment and the redundant grease on the ground will bring safety hazards. To strictly abide by these steps, especially should focus on SONY bearing company also can get more information. In the case of a hard soap precipitation, using hot oil from the oil gun flushing bearing box. To ensure that the replacement with new grease before running out all the old oil bearing inner. If large is to be developed all the grease in the bearing is not too realistic, special bearing large equipment. Please according to the manufacturer's instructions to determine the bearing grease additives. Please note that is not normal bearing running 'danger signals, such as abnormal noise, vibration and temperature. Ensure that pay more attention to these signs of great help to maintain normal operation. Local bearing condition monitoring instrument available to assist detection of adverse operating conditions. （ Source: cotton home)
