Rotary kiln size gear oil leak reason and solution

Rotary kiln size gear oil leak reason and solution - 2019 02 - 14 rotary kiln is the heart of the cement plant equipment, continuous operation, and low speed, overload, high temperature, tilt, dust environment, and many other features, especially the main drive gear size, heat expansion influence, but also the priority of equipment management. In recent years, with the development of lubrication technology progress, main drive gear lubrication problem of large rotary kiln has been basically resolved, immersion fluid lubrication grease is believed to be reliable and mature solution. However, fluid grease has good liquidity, and creates new problems, is the leak. Oil spill, it is a waste of lubricant, 2 is caused by environmental pollution, more seriously, if oil fell to high temperature on the cylinder, will burst into flames. On the issue below, analyze its reasons, and put forward solutions. 1 a, oil leak reason analysis. Big gear cover leakage cause analysis, it is well known that rotary kiln is inclined to install. In the process of rotary kiln body, big gear will bring up many oils, the grease in the process of upward movement, will flow down. But felt is able to resist the grease, hence forming lubricant leaks, namely the spill. 2. Small gear cover leakage cause analysis, general rules, we add quantity of lubricant to drown pinion two to three teeth. At this point, cleave to the gear surface lubricant is evener, quantity is less, redundant can flow back to the oil pool in time, will not leak. Even if there is leakage, quantity is less, by cleaning up can be kept clean. But, we in the production practice, the oil pool of oil level tend to be high, some even up to the pinion shaft. At this point, the pinion drive lubricating grease is very much, will form a 'oil falls. The lubrication oil will flow into the pinion shaft, the small gear is installed, oil to flow down the pinion shaft. Small gear cover sealing felt is unable to block the oil flow, then form the spill. Two solution, oil lubrication is indispensable, oil leakage cannot be used to reduce the number of solution. Here the oil solution is' persuation '. 1. Big gear cover leakage solution transform the structure of large gear cover, make to the top of the big gear oil, oil well flow back to the pool again. 2. Small gear cover leakage solution on the pinion shaft add oil baffle plate, make cleave to the grease of the pinion, cannot pass flow gear axle housings, but is blocked by oil baffle plate, back to the oil pool again.
