A gear set is a complete transmission unit composed of two or more gears that mesh with each other, and can achieve constant speed ratio, variable speed, or power splitting between parallel, intersecting, or staggered axes. This series of products is made of high-strength alloy steel, stainless steel, or engineering plastics, and undergoes precision gear rolling/grinding and heat treatment processes. It has the characteristics of low noise, high load-bearing capacity, and long service life, and is widely used in industrial automation, robotics, automotive, medical, agricultural, and household appliances fields. Tooth surface precision grinding+shaping technology, noise ≤ 65 dB (3000 rpm, no load). One stop machining of aperture, keyway, thread, flange, and double gear.
