WHS Circular Cylindrical Worm Gear Reducer
The WHS circular arc tooth cylindrical worm gear reducer adopts a cylindrical worm gear with a shaft section of circular arc shape
Product details
The WHS circular arc cylindrical worm gear reducer adopts a cylindrical worm gear with a shaft cross-section of circular arc shape. The worm gear tooth shape is conjugate with the worm gear in a circular arc shape. Due to the convex concave meshing between the worm gear and the worm gear, the majority of the comprehensive curvature radius in the meshing area is large, which reduces the tooth surface stress, increases the tooth surface strength, and improves the bearing capacity. At the same time, the tooth shape reasonably reduces the thickness of the worm gear tooth and increases the thickness of the worm gear tooth plate, thus increasing the bending strength and transmission capacity of the worm gear tooth plate. In addition, the angle between the contact line and the circumferential velocity is mostly between 40 ° and 90 °, which is easy to form liquid lubrication. The friction coefficient between the tooth surfaces is small, so the efficiency is high and the temperature is low. This product complies with JB2318-79 standard) WHS universal circular arc tooth cylindrical worm gear reducer with worm gear on top. Suitable for deceleration transmission of various mechanical equipment in metallurgy, mining, lifting, transportation, chemical industry, construction, etc. The input power range of this series of reducers is between 0.4 and 163KW; The output torque is between 11 and 2600 kgf · m, and the input shaft speed is generally not greater than 1500 revolutions per minute; The high-speed shaft can operate in both directions; The working environment temperature ranges from -40 ℃ to 45 ℃; When the working environment temperature is below 0 ℃, the lubricating oil must be heated to above 0 ℃ before starting. This product has sixteen center distances ranging from 120 to 500, nine speed ratios including 8, 10, 12.5, 16, 20, 25, 35, 40, and 50, and five assembly forms. And various non-standard reducers can be designed and produced according to user needs.Method for representing gearbox model:
