The circular cylindrical worm gear reduction adopts single-stage worm reduction transmission, which conforms to the national standard GB9147-88. This standard has reached the international level in the 1980s. The full range of cast iron housing industrial worm speed reducer includes three models, sixteen center distances and twelve speed ratios. The input power range is between 0.39 and 189 kW and the output torque is between 107 and 43500 N.m. Since the worm wheel and the worm are convex and concave, most of the integrated radius of curvature in the meshing area is large, thereby reducing the tooth surface stress, increasing the tooth surface strength, and improving the bearing capacity, and the tooth shape reasonably thins the worm tooth thickness. Increases the root thickness of the worm gear, so the bending strength of the worm gear root increases, the transmission capacity increases, and the angle between the contact line and the peripheral speed is mostly between 40° and 90°, which is easy to form liquid lubrication. The coefficient of friction between the faces is small, so the efficiency is high and the temperature is low.

There are many types of CW series turbine gear box transmission, including: CWU worm in the down type, CWS worm in the side type, CWO worm in the upper type

There are 16 types of a=63, 80, 100, 125, 140, 160, 180, 200, 225, 250, 280, 315, 355, 400, 450, 500.

There are 12 kinds of transmission ratios i=5, 6.3, 8, 10, 12.5, 16, 20, 25, 31.5, 40, 50, 63

CW: arc-tooth cylindrical worm gear unit U: worm position, "U" is lower, "O" is upper, "S" is side. 200 is center distance (mm) 20 is the nominal transmission ratio

The worm shaft of the reducer can be operated in both forward and reverse directions. The input speed does not exceed 1500r/min, and the working environment temperature is -40-40°C. When the working environment temperature is lower than 0 °C, the lubricating oil must be heated above 0 °C before starting; when the working environment temperature is higher than 40 °C, cooling measures must be taken.

CW Series arc cylindrical worm gear reducer features:

  1. The transmission is stable, vibration, shock and noise are small, the reduction ratio is large, the versatility is wide, and it can be used with various mechanical equipments.
  2. It can obtain a large transmission ratio with single-stage transmission, and has a compact structure. Most models have better self-locking performance, and can save braking devices for mechanical equipment with braking requirements.
  3. The meshing friction loss of the worm tooth and the worm gear tooth surface is large, so the transmission efficiency is lower than the gear, easy to heat and high temperature.
  4. Higher requirements for lubrication and cooling.
