Mechanical transmission is the most common in mechanical engineering. It is widely used to transmit force and friction transmission mainly by friction force of machine parts, including belt transmission, rope transmission and friction wheel transmission. Basic product classification: reducer, brake, clutch, coupling, stepless speed changer, lead screw and slide rail etc.
And gear transmission is one of the main transmission modes of mechanical transmission. Its running state will directly affect the working state of mechanical system. The maintenance of gear is to reduce the wear and tear in transmission and also to improve the life expectancy.
Oil leakage from gearbox oil seal is common and difficult to cure.
The traditional way is to replace the oil seal, which costs thousands of dollars each time and takes three to four days to complete. For the power transmission mechanism of speed reducer, which is an important equipment cluster in cement enterprises, daily maintenance and management are more important. The common problems are the wear of bearing seats, gear damage, oil leakage of dynamic and static seals, and damage of skeleton oil seals.
Ninety percent of the oil leakage is caused by oil seal corrosion and aging, especially rubber oil seals will lose plasticizer due to long-term temperature changes caused by alternating changes in temperature. The final result is that the oil seal shrinks and hardens, resulting in loss of elasticity and even more serious breakage. However, breakage generally does not occur. When oil leakage occurs, we will find it during maintenance and will not deal with it until breakage occurs.
Regular inspection, correct installation and adding lubricant can effectively increase the service life of the oil seal, but fundamentally speaking, a good oil seal should be selected, otherwise the symptoms will not be treated at the root of the problem and the oil seal will be replaced. Frequent replacement of oil seals takes time and effort.
