Abstract

The invention discloses a lower roll synchronous transmission device of a four-roll veneer reeling machine, which comprises a main control unit and two rotational speed control units, the rotational speed control units are connected at the two ends of the to-be-controlled lower roll respectively, and the main control unit is connected with both of the two rotational speed control units. The device provided by the invention is simple in structure, can control rotational speed of the two lower ends of the lower roll synchronously, enables the lower roll not to be deformed under normal work, and is small in driving power, convenient to mount and maintain and convenient to modify parameter, and the device rolling range is wide.

Description

Technical field: [0001] The invention relates to a synchronous transmission device for the lower roll of a plate rolling machine. Background technique: [0002] The lower roll of the large-scale four-roller plate rolling machine is slender, and the lower roll is the main drive roll, which bears the pressing force of the upper and lower pressing of the plate and the main transmission torque required for rolling the plate. Under high pressure and large transmission torque, the stressed structure of the lower roll becomes the key part of the whole plate rolling machine. If the torque is transmitted from one end of the lower roller, the lower roller will have a large twist deformation, and in severe cases, it will cause permanent deformation and the roller shaft will be damaged. The rotation angle displacement synchronization accuracy of the lower working roller of the plate rolling machine will directly affect the rolling quality. It even affects the normal use and life of the...
