Characteristic: 1. High quality gear profiles 2.High load ability, high strength & high efficiency 3.Improvement in Contact-line position A contact-line position or a contact area can be improved by way of changing an inclination angle of a worm tooth 4.Increased simultaneous interlocking Number of teeth interlocking at a time may be more than tripled as compared with a cylindrical worm reducer 5.Reduced Size & Weight Size of wheel may be made smaller by about 30% as compared with a cylindrical worm gear, resulting in considerable reduction also in weight 6.Reduction in Pressure on Unit Surface 7.Durable bearing Ball and roller bearing are used in our standard models and they are designed to be sufficiently strong in meeting any demands by our customers. Special considerations are also given to a sealing device to protect bearings from dusts or any other foreign materials.
