Packing List: 2 pc x Mod 2M20T helical Pinion This offer is for Bevel Pinion Teeth Mod 1.5/2/2.5/3 Gear helical Teeth in #45 Steel. Main featuresï¼ The tooth shape of the spiral bevel gear is a circular arc shape, and generally is tapered, like an umbrella shape, hence the name spiral bevel gear. Spiral bevel gear is a kind of transmission component that can be driven stably and with low noise according to stable transmission ratio. It has different names in different regions, also called spiral bevel gear, spiral bevel gear, spiral bevel gear, arc bevel gear, Spiral bevel gears, etc. The spiral bevel gear has high transmission efficiency, stable transmission ratio, large arc overlap coefficient, high bearing capacity, smooth and smooth transmission, reliable operation, compact structure, energy saving, space saving, wear resistance, long service life and low noise. Among various mechanical transmissions, the transmission efficiency of spiral bevel gears is the highest, which has great economic benefits for all kinds of transmissions, especially high-power transmissions. the transmission parts of transmission parts required for transmitting the same torque are the most space-saving, than belts, The space required for chain drive is small. the spiral bevel gear transmission ratio is permanently stable, and the transmission ratio is stable. It is the basic requirement for transmission performance in the transmission of various mechanical equipment. the spiral bevel gear works reliably and has a long service life. Process holes may vary depending on the batch. If you need accurate inner holes, please contact us. note we also provide the other size gears and racks We also provide ballscrew, square rail, guide rail, switching power supply, motor, drive board, spindle, coupling, bearing, drag chain ,power supply and other cnc machine. window.adminAccount
