Shanghai Zhongwei Machinery envelope transmission plant

I designed the production of Planar Double-Enveloping Worm reducer because of its excellent quality and its unique advantages of the mechanical transmission by a wide range of the machinery industry and mechanical designers welcome. At present, the widespread use of gear in the metallurgy, mining, construction, shipbuilding and other industries and has been unanimously praised. Planar Double-Enveloping Worm Gearing, in addition to containing general cylindrical worm, arc cylindrical worm, Worm, such as the merits of transmission it has the following main features; 1; bearing capacity of large, inclusive Worm Worm gear up to four or more teethAnd reduce the tooth surface compressive stress, which greatly raised the carrying capacity. With ordinary cylindrical worm drive compared to the

same conditions for more than four-fold increase in the carrying capacity of .2; drive high efficiency, multi-tooth, and contraction of the two contact so that the evolution of the total tooth surface to be a small change of the oil from the cavity, the tooth surface to ensure good dynamic pressure of the liquid film lubrication, which reduces the friction coefficient to improve the transmission efficiency and service life. than with the standard power-saving ordinary worm .3 ; life long after the worm tooth surface hardened precision grinding, the hardness of tooth and manufacture of high precisionSurface finish higher. Bronze worm gear selection and use of centrifugal casting.
