Solution to the oil leakage problem of band saw blade 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 cap is too small, and the oil return is blocked, which may 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 many 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, the pressure in the crankcase will increase, which will result 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.
 
 
 
 
Safety operation regulations for band saw blade gear grinding machine
 
1. Before starting the machine, check the screws of all parts, whether the adjusting screws are tight and tight enough, whether the grinding wheel is scratched, chipped, or loose, and add grease to each part.
 
2. According to the tooth pitch, tooth height, and bevel angle (inclination angle) of the saw blade. Adjust the distance of the pedaling teeth and the stroke of the gearing, so that the crossbar claws of the pedaling teeth are at 1/2 of the height of the tooth throat, and adjust the inclination angle and lifting height of the grinding wheel holder.
 
3. The rotation, rising and falling of the grinding wheel must be balanced, and there is no jumping or stringing phenomenon. In the event of vibration and uneven pedaling, it should be eliminated before it can work. The machine must not sharpen any parts other than saw blades.
 
4. You must choose and use the grinding wheel that meets the requirements (certificate, particle size, linear speed standard). Operators should not stand at the front and back of the rotation direction of the grinding wheel and should stand on the side.
 
5. After the work is completed, the dust on the equipment must be removed, especially the cam of the wheel carriage slide, to reduce equipment wear.
