under normal circumstances, double row deep groove ball bearing temperature should be around 30 ℃, the highest temperature should not exceed 70 degrees celsius, otherwise, the deformation caused by bearing temperature is too high, severe cases can make the jaw crusher direct damage, what's more, as a direct result of blast machine. therefore, alert to jaw crusher bearing temperature, especially in the summer, more urgent.
a cage, bearing wear or damaged. second, the adapter bushing axial channeling move. three, bearing fault oil or oil injected too much. four, crusher run partial fly geneva wheel balance weight block position, frame beat. five, the oil hole blockage, add oil. six, bearing temperature, but the moving jaw gland and end cover frame bearing friction heat or both embedded cover with the spindle rotation, the friction heat.
1. keep the bearing lubrication clean
inspection on double row deep groove ball bearing surface should be clean before bearing, and then carefully check bearing oil seal and its surrounding parts, if has presented the adverse symptoms, be sure to replace the bad oil seal will cause damage to the bearing cloud caused by abnormal equipment downtime.
2. pay attention to cover exposed bearing
check the bearing when don't let the noise of double row deep groove ball bearing exposure to pollutants or moisture environment. if the job is interrupted, should with oil film, paper or similar material by machine. if don't have to remove and may perform inspection of cleaning without masking of bearing, to clean with brush with petroleum solvent coating, then dry with a lint-free cloth or use compressed air to blow dry (be careful not to let the bearing component starting rotation).
