What is the lifespan of the gearbox of an inverted wire drawing machine?


Release time:

2023-07-10

The gearbox of an inverted wire drawing machine is the main part of an inverted wire drawing machine, also known as a reducer. Like commonly used horizontal JZQ reducers or cycloidal pinwheel reducers, it plays a role in reducing speed and increasing torque. Common reducers are mostly national standard models, with corresponding mechanical standards for speed ratios and motor sizes. The gearbox of the inverted wire drawing machine is self-developed and designed according to the operational needs of the equipment. The installation size and speed ratio are determined according to the wire drawing needs.
The gearbox of the inverted wire drawing machine is divided into three levels of transmission. The first level is bevel gear transmission, which changes the direction of force. The last two levels of transmission are both cylindrical helical gear transmission. The first stage bevel gear is made of high-quality material, 40 chromium molybdenum, which has good wear resistance and impact resistance. The processed gear is also subjected to gear grinding and heat treatment, making the transmission noise small and the clearance fit good. The secondary and tertiary transmission gears of the gearbox of the inverted wire drawing machine are made of 45 # steel and cast. After being processed and heat treated by a hobbing machine, the gears also meet certain matching requirements.
Two thirds of the Gear oil shall be added to the gearbox of the inverted wire drawing machine before use, and the inverted wire drawing machine shall be started for idling to let the gears in the gearbox run in for a period of time, so that the gears at the upper position also have lubricating oil to maintain the lubrication of the entire gearbox. The service life of the gearbox of the inverted wire drawing machine is properly maintained, with a general service life of about ten years. When starting the machine, follow certain steps and do not forcefully start it. Check the gearbox once a month to see if there is any shortage of oil or oil leakage. If it is repaired in a timely manner, if the gearbox of an inverted wire drawing machine is short of oil for a long time, the gears cannot be lubricated, and the friction coefficient between the gears increases. In severe cases, tooth breakage may occur, causing unnecessary trouble.
