How long is the service life of WS210-41-V worm gear reducer
The service life of WS210-41-V worm gear reducer is affected by various factors. Generally speaking, under normal use and maintenance conditions, its service life is usually around 5-10 years. But if the design is reasonable, the material selection is appropriate, and the maintenance is proper, its service life may also be longer, even up to 10 years or more. The following is an analysis of specific influencing factors:
Materials and Manufacturing Process: If the worm gear is made of high-strength alloy steel such as 40Cr, 20CrMnTi, etc., and undergoes quenching or carburizing quenching treatment, and the worm gear is made of wear-resistant materials such as tin bronze or aluminum bronze, with a machining accuracy not lower than level 7 in GB/T 10089 and a tooth surface roughness Ra ≤ 1.6 μ m, then the wear resistance of the reducer will be better and the service life will be correspondingly extended.
Lubrication conditions: Choosing the appropriate lubricant is crucial. For ordinary working conditions, using high viscosity mineral oil or worm gear special oil (containing extreme pressure anti-wear additives), and using synthetic lubricating oil for high-speed/heavy-duty working conditions can effectively reduce friction between worm gears and reduce wear. At the same time, it is necessary to regularly replace the lubricating oil. After running the new reducer for 500 hours, the lubricating oil should be replaced to remove metal debris generated during running in. Afterwards, the oil should be changed every 2000-3000 hours or annually (whichever comes first).
Load situation: If the gearbox operates for a long time beyond the rated load, or starts and stops frequently, it will increase the friction and wear between the worm gear and worm, thereby shortening its service life. Therefore, it should be strictly used according to the rated load, and short-term overload should not exceed 1.5 times the rated torque, with a duration of less than 10 minutes.
Working environment: High temperature, humidity, corrosive gases or dust in the working environment can have adverse effects on the service life of the gearbox. For example, in high temperature environments, the performance of lubricating oil may decrease, which may lead to poor lubrication; In environments with corrosive gases, the components of the gearbox are prone to corrosion. Generally speaking, the working environment temperature of worm gear reducers is -40 ℃ -+40 ℃. If it exceeds this range, corresponding cooling or heating measures may need to be taken.
Installation and maintenance: During installation, it is necessary to ensure that the perpendicularity of the axis between the worm gear and the worm wheel is ≤ 0.02mm/100mm, and the center distance error is ≤ ± 0.05mm. Use a special fixture or dial gauge to calibrate the coupling alignment, and the coaxiality error of the transmission system is ≤ 0.03mm to avoid additional wear caused by improper installation. At the same time, a regular inspection system should be established to check the operating sound, oil temperature, vibration, etc. every day, check the oil level every week, and promptly deal with abnormal situations.
