Specifications

Self-aligned welding rotator includes one power and one idle, after loading the work piece, the rollers will auto suit the work piece, no need to adjust the center distance. This welding rotator mainly consists of powered rotator, idle rotator, driving reducer system, control system etc. It is mainly used for longitudinal and circular seam welding of cylinders together with the submerged arc welder.

1. 1.The structure parts of the rotator has the annealing treatment after welding,which can ensure the long-term using performance and service life.
2. 2.The rotator adopts reasonable structure with good rigidity. The mechanical transmission is equipped with dust proof device, as well as good abrasion proof performance.
3. 3.The transmission mechanism: motor---multi-step speed adjust----roll, the roller speed adopts frequency speed adjusting.
4. 4.The rollers use rubber casting with abrasion resistance and long service life. The PU roller and metal roller also can be customized according to users’requirement.
5. 5.The four rollers of the rotator are all powered rollers, adopt double driving system. The driving motor adopts AC motor, driving system has the functions of voltage protection and overload protection.
6. 6.Base sliding surface adopts finish machining, mounting and fixing hole is designed on it. By fixing the rotator via holes with different position, then the center distance of rotator will be changed to suit the using requirement of different work-piece.
7. 7.The lubrication system is designed on each motion part of the rotator with refueling device and seal dust-proof device.
8. 8.All of the operation for rotator can be centralized on one remote control panel with E-stop button on it.
9. 9.The base of motor has enough rigidity. When rated loading, the down-warp deformation won’t affect the normal using. At the same time, the rotator has overload capacity within some limits .

A1: The self-aligned welding rotator is driven by one AC variable frequency motor to drive two gear reducers to rotate at the same time. Compared with ordinary motors, variable frequency motor has lower noise and smaller electromagnetic vibration.

A2: Schneider AC variable frequency governor is mainly used to control and adjust the speed of three-phase AC asynchronous motors, with stable performance, rich combination functions, good dynamic  characteristics, super overload capacity and unparalleled flexibility.  The linear speed of the roller is 100-1000 mm/min, the adjustment  response accuracy is high, and the speed operation is stable and  reliable.

A3: IP65 ingress protection electric cabinet has the protection function for field use。The wiring is neat and the grounding signs are clear.The operation panel has the functions of forward、 reverse and stop. The speed is adjusted by the rotary button and displayed on the display screen.

A4: Compared with ordinary rubber wheels, PU rollers have better bearing effect, wear resistance, acid resistance and high temperature resistance.

A5: Compared with ordinary bearings, the imported bearings has the advantages of higher limit speed, higher load resistance, lower noise and longer service life. Greatly improved the quality of our products.
