Transmission system of mask machine

The transmission system includes motors, gears, reducers, sprockets, chains, conveyor belts and other components. Let's check whether there are dust and other things on the outer surface of the motor that affect heat dissipation. Are the gears and sprockets oiled or attached? Is the chain tightness suitable for foreign matter? Is the connection screw between the transmission parts loose? Is the lubricant of the reducer sufficient? It is usually necessary to replace the lubricating oil once every 1000 hours to 1500 hours.
