20CrMnTi 180 Polishing Machine Spiral Bevel Gear Set (Z=7/46)

Product Specification

20CrMnTi 180 Polishing Machine Spiral Bevel Gear Set (Z=7/46)

20CrMnTi 180 Polishing Machine Spiral Bevel Gear Set (Z=7/46) is a high-precision transmission component specifically designed for 180-type polishing machines, angle grinders, and related power tools. The gear set consists of a 7-tooth pinion gear and a 46-tooth bevel gear, providing an approximate transmission ratio of 6.57:1. It enables the conversion of high-speed motor output into low-speed, high-torque output, effectively improving the efficiency and stability of polishing, grinding, and cutting operations. It is widely used in metal processing, stone processing, woodworking manufacturing, construction engineering, power tools, and industrial equipment applications.
