What are the factors of gear pitting and shedding of reducer?
Answer: a material, hardness and defects.The gear material does not meet the requirements; the primary factor affecting the contact fatigue strength of the gear is the low hardness after heat treatment, which cannot guarantee the proper contact fatigue strength of the gear.In addition, defects on the surface or inside of teeth are also one of the indispensable factors for contact fatigue strength.
b. Poor gear accuracy.Gear processing and equipment accuracy do not meet the requirements, such as poor meshing accuracy and motion accuracy.In addition, the base distance of the shell of the arc gear is too large.
c.The lubricating oil does not meet the requirements.The grade of lubricating oil used is wrong, the viscosity of the oil is low, and the lubricating function is poor.
d. The oil level is too high.If the oil level is too high, the oil temperature will rise, the viscosity of the lubricating oil will decrease, the lubrication function will be destroyed, and the working thickness of the oil film will be reduced.
