Shenzhen worm worm drive non-calibration for motion and power transmission space staggered between the two axes. Growth or slow movement may be, the most commonly used is the stagger angle of 90 ° deceleration both axes. Helix direction may be right- or left, and more generally to take the right-handed. Direction of the worm and helical turbine must be consistent. Worm drive vibration, shock and noise are very small, working more stable, able to obtain a larger single-stage transmission gear ratio, compact, can be self-locking. Its main drawback is the low ratio gear transmission efficiency, friction reduction need expensive non-ferrous metals. My company mainly produces: spur gears, gear shafts, small module gear, spiral bevel gear (bevel gear) helical gears, worm gears and other special-shaped (various materials) can be customized, such as a large number of standard models, high quality inexpensive, large more favorable. Sincerely look forward to working with you! Shenzhen OECD Gear Machinery Co., Shenzhen worm non-calibration
