Abstract

The invention belongs to the technical field of transmission equipment, and particularly relates to a ring rolling machine conical roller transmission structure and method.The ring rolling machine conical roller transmission structure comprises a conical roller, a gear motor and a transmission connecting part, the conical roller is installed on a frame, and a main shaft of the gear motor is of a hollow structure; a main shaft of the speed reducing motor is coaxially matched with the extension section of the conical roller through a shaft sleeve, and transmission connection is realized through a transmission connecting part; in the transmission process, the two thrust bearings bear the axial force of the conical roller, the cylindrical bearing supports the conical roller extension section in the radial direction, axial movement and radial shaking of the conical roller extension section are effectively avoided, and it is guaranteed that torque transmission is accurate, and transmission is stable; meanwhile, the connection mode of all the components is detachable and adaptive, maintenance and replacement of a single component are facilitated, the equipment failure rate is further reduced, and the overall service life of the transmission structure is prolonged.
