The gear accuracy of the gear reducer stipulates 12 levels. The numbers 1, 2, and 3 are used in order from high to low accuracy. The commonly used ones are 5 to 9 levels of accuracy.The accuracy level of the gear reducer gear should be determined based on the purpose of the transmission, usage conditions, transmission efficiency and peripheral speed, and other economic and technical indicators.Level 5 gears are precision level.Processing method: Processing on precision gear machine tools with very small periodic errors.The tooth surface is finally precision ground, and large gears are hobbing with precision hobbing and then ground or shaving.Level 7 gears are a relatively high precision level.Processing method: Processed on high-precision gear machine tools.The tooth surfaces that are not quenched are cut with high-precision tools; the quenched gears require finishing (grinding, shaving, grinding, etc.).The tooth surface roughness reaches 1.6.
The gears are made of high-strength low-carbon alloy steel through carburizing and quenching. The tooth surface hardness reaches HRC58-62. The gears all adopt CNC gear grinding technology, which has high precision and good contact.High transmission rate: single-stage is greater than 96.5%, double-stage is greater than 93%, and three-stage is greater than 90%.Smooth operation and low noise.Small size, light weight, long service life and high carrying capacity.
