Gear transmission is the most widely used transmission method in the application of mechanical transmission components. Plastic gears are one of the gear products. Its light weight, low transmission noise, higher gears, and higher load-bearing capacity are becoming stronger and stronger. It is increasingly used in various fields. The more extensive. Gear transmission requires accurate, smooth and uniform gear transmission, especially high-end products require gear accuracy, so lubrication is very important.
However, when choosing the grease for plastic gears, most people pay attention to the continuous lubrication of plastic gears, effectively reduce noise, stable performance, etc., and ignore the compatibility of gear materials and grease.
When gears made of plastic materials are in contact with lubricants, such as improper material polarity, material formulations that are not resistant to oil, and large residual stress in the parts, volume expansion, shrinkage, cracks, and mechanical performance degradation may occur. The slightest phenomenon will lead to mechanical failure, while the serious one will endanger life safety. Gear parts technicians should consider material compatibility factors when selecting plastic materials and lubricants, and if necessary, arrange material compatibility tests before sample experiment certification to ensure good compatibility.
