helical worm gear motors Characteristics

S37 series helical worm gear motors adopts the helical worm gears to make its structure more reasonable. S series not only has higher transmission efficiency and loading capability than those single-stage worm wheel transmission, but also smaller volume and appearance. Moreover, S series Helical Worm Gear Drives has higher transmission ratio, and can be combined with various gearboxes and speed variator to meet the different requirements.

S series Helical Worm Gear Drives has more sizes with a reduced variety of parts Increased power capacity, lower noise and higher efficiency by grinding and modifying gear The all-in-one box provides higher rigidity and higher vibration resistance. More ratios satisfy the need of accurate output speed. Helical Worm Gear Drives can be supplied for either horizontal or vertical installation in any angles.
