I. There are many basic forms of parallel shaft reducers. This is a parallel shaft bevel gear reducer, with its output method being parallel shaft. The feature of parallel shafts is the adoption of unit structure modular design principles, which greatly reduces the types of parts and inventory, as well as significantly shortens the delivery cycle. The cast iron housing with ribs has high rigidity, and the gears are made of high-quality alloy steel, treated with carburizing and quench hardening on the surface, precision ground, resulting in smooth transmission, low noise, high load-bearing capacity, low temperature rise, and long service life. It is suitable for high-precision machining, but the drawback is that the cost is relatively high.
