Solution to the oil leakage problem of TCT saw blade gear grinding machine

① First, check whether there is any oil leakage outside.

Pay special attention to whether the oil seals at the front and rear ends of the crankshaft are leaking. Cracking and aging of the front end oil seal of the crankshaft or wear of the contact surface between the crankshaft pulley and the oil seal may cause oil leakage at the front end of the crankshaft. The oil seal at the rear end of the crankshaft is broken and damaged, or the oil return hole of the rear main bearing cover is too small, and the oil return is blocked, which will cause oil leakage at the rear end of the crankshaft. In addition, pay attention to whether the oil seal at the rear end of the camshaft is leaking. The oil seal should be replaced in time if the oil seal is aging or broken. In addition, it is necessary to check whether there is any leakage of the parts of the engine lubrication system.

②If oil leaks at the front and rear oil seals

Even the front and rear cylinder head covers, front and rear valve lifter chambers, oil filters, oil pan gaskets and other places where organic oil seeps, but no obvious oil leaks can be found, check the crankcase ventilation device and clean the crankshaft The ventilation ducts of the tank, especially to check whether the PCV valve does not work badly due to carbon deposits and glue sticking. If the crankcase is poorly ventilated, it is likely to cause the pressure in the crankcase to rise, resulting in multiple oil leakage.

③If the oil filter and some oil pipeline joints still leak after being tightened, check whether the oil pressure is too high and the oil pressure limiting valve is not working properly.

Product.jpg How to choose the grinding oil for alloy saw blade gear grinding machine Do you know how to choose the grinding oil for gear grinding machines? Release time: 2019-04-18

Gear grinding machine is a kind of precision instrument, which has strict requirements in all aspects. So, do you mean it's choice of grinding oil? The editor of Kappa will introduce the following content to you, I hope it can help you. Gear grinding is a finishing process, which requires high surface burns and strains. Therefore, the viscosity of the gear grinding oil is very important. If the lubricity is low, strains will occur, and if the heat dissipation is high, burns may occur. The instantaneous temperature of the oil during grinding gear processing can reach 130°C-140°C. Therefore, the oil is required to have a high flash point. Generally, the flash point of the grinding oil should not be lower than 160°C. The excessively high temperature will produce oily smoke and oil mist which will cause certain harm to workers. Especially in a sealed and constant temperature processing environment, although the grinding oil cannot completely eliminate the generation of smoke, it can be suppressed by additives. To reduce the harm to workers.

Worm mills have an average grinding wheel speed of about 3000 revolutions. The requirements for smoke are higher than those for forming grinding. The flash point should be above 170, which can reduce smoke generation. At the same time, it has high requirements for extreme pressure, and the relative viscosity of the forming gear can be slightly higher. ~5, because the speed is fast, if the lubricity is not good, it may cause strain and burns. On the contrary, if the viscosity is too large, the heat dissipation of processing will not be good, and it will also cause local burns. Therefore, the worm gear grinding machine should choose the viscosity of 14 at 40℃ Between ~16, a grinding oil with a flash point of ≥175 or more without sulfur and chlorine molecules.
