Product introduction

  Automatic self-adjusting welding rotator can adjust itself according to the diameter of cylinder. Its drive adopts cycloidal pinwheel reducer or worm gear reducer, dual motor drive. According to the needs of users, the roller can be divided into rubber wheel, steel wheel and The roller frame is mainly used for welding, the lining and assembling of cylindrical cylinders, and also for assembling and welding conical and sectional unequal-diameter revolving bodies in combination with other assemblies. 

welding rotator design

  This product is widely used in wind power, pressure vessel, petrochemical, pipeline, steel structure, boiler, shipbuilding, surfacing repair and other industries. Our factory can also design and customize various types of roller racks according to the needs of users.

1.The physical construction of the self-adjusting roller:

  Self-adjusting roller is composed of primary frame and secondary frame .The primary part is composed of foundation, motor, transmission gear, swing arm and wheels.The secondary part is composed of foundation, swing arm and wheels.

2.Working principle and structure characteristics:

  The working way of Self-adjusting rollers is that active frame,two motors and reducer controlled by the same ac motor driver realize the two motors stepless speed change and synchronization operation. The motor drive the main driving wheel working through drive system.

  The work piece is putted on the primary and secondary wheels, when the primary wheel running, the friction between workp iece and primary wheel can drive the work piece rotating. The friction between rotating work piece and secondary wheel can drive the secondary wheel running.

pipe rotators

  Each swing arms of the self-adjusting roller can drive work piece to adjust the diameter by itself, so that the labour power is saved much and the work efficiency is increased.


Adjustable electric screw or manual screw, convenient and efficient;

The roll wrap angle is 45 ° ~ 110 ° to ensure the stable rotation of the workpiece;

AC motor or DC motor (as required by the customer) drives the worm gear reducer to drive the roller to rotate through the gear;

French Schneider or Japanese Panasonic frequency converter realizes variable frequency stepless speed and synchronous rotation of roller;
