The detailed content of WHS arc tooth cylindrical worm reducer includes four series: WHT (universal type), WHX (worm below the worm wheel), WHS (worm above the worm wheel), and WHC (worm on the side of the worm wheel). It is mainly used for deceleration transmission of various machinery and equipment in metallurgy, mining lifting, transportation, chemical industry, construction, etc. The operating environment temperature is 0 ℃~45 ℃, and the high-speed shaft can be transported in both directions. The worm speed is ≤ 1500r/min. 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 root. Therefore, the bending strength of the worm gear root increases, and the transmission capacity increases. In addition, the angle between the touch line and the circumferential velocity is mostly between 40 ° and 90 °, which is easy to form a smooth liquid. The friction coefficient between the tooth surfaces is small, so the efficiency is high and the temperature is low. The WHS circular tooth cylindrical worm gear reducer conforms to the JB2318-79 standard, and the WHX worm gear can be a circular tooth cylindrical worm gear reducer under the worm wheel. Suitable for deceleration transmission of various mechanical equipment in metallurgy, mining, lifting, transportation, chemical industry, construction, etc. The input power range of WHS circular tooth cylindrical worm gear reducer 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 forward and reverse directions; The operating environment temperature ranges from -40 ℃ to 45 ℃; When the operating environment temperature is below 0 ℃, it is necessary to heat the lubricating oil to above 0 ℃ before starting. Base distance: 120, 125, 150, 160, 180, 200, 210, 25O, 280, 300, 320, 360, 400, 420, 450, 500, speed ratios: 8, 10, 12.5, 16, 20, 25, 31.5, 40, 50.
