150T bolt Heavy Duty Rotator Turning Rolls Steel / Polyurethane
Conventional Rotators are built in capacities from 1T to 2000
tonnes. The frame is of robust fabricated construction and is
machining on the top and underneath to ensure perfect alignment.
Both the drive and the idler frames are provided with robust
fabricated and machined wheel brackets which support the axles and
bearings of the rollers.
The equipment mainly consists of drive rotator, idler rotator and
electrical control system etc. Drive rotator is made up of base,
pedestal, rollers and drive device, idler rotator without drive
(1)pedestal and roller base are welded structure, all the strength
of the weld seam according to requirements such as welding, heat
treatment after welding were annealed to remove internal stress and
effective prevention of welding deformation.
(2)Drive device located on the two roller beds of the droved
rotator, Drive device are consist of
reducer and motor. The reducer adopts the special design gear and
wheel reducer and which made by our company, with high transmission
efficiency, large output moment. Drive unit droved by AC frequency
conversion motor, and through reducer, thus drive the roller
turning. The turning speed is VFD, and the speed can be adjusted in
the range of 100-1000mm/min, and it can realize different welding
requirement of different size work piece. Both drive and idler
rotator equipped with traveling unit, easy for operating, and the
idler unit with manual lock device, it can quick lock rotator on
the rail. On the base of drive rotator equipped with a set of
traveling motor, and traveling consists by two bevel gear reducer
and two 1.5 KW motor, gear and wheel couple, and the drive and
idler rotator droved on the rail by bevel gear reducer and gear and
rack couple, traveling smoothly and convenient operating.
(3)The rollers are all Polyurethane material and without metal.
Roller center distance can be adjusted to realize different size
workpiece. When adjusting, just move the position of symmetrical
roller seat, then fixed by bolts, easy and convenient, also with
large anti-wallop strength..
(4)The equipment side of the idler rotator fitted with a mechanical
gear wheel, gear wheel fixed in the holder with the rotating
cylinder, while the rotation of power, to meet the welding
requirements of different size cylinder workpiece, to prevent the
shifting of the workpiece in the welding process holder behind the
installation of a locking device to prevent the roller frame roll.
(5)Electric control system mainly consists of electric control box
and remote panel. There are inverter, relay, terminal etc in the
control box. Power switch is mounted on the door of electric
control box. The alarm indication, alarm clear button on the panel
of control box; the remote panel has roller forward, backward, stop
This bolt adjustable welding rotator is produced according to MMBEI
Standard ZBJ33003-1990. Self-design and manufacture combined the
advantages of oversea competitors and requirements of domestic and
overseas customers. It is suitable for automatic welding of
circular seam cylinder, with advantages of practical, reliable,
stable and easily operates etc. It is widely used in the range of
job cutting, polishing, assemble etc.. It is one of ideal
equipments of improve automaticity and efficiency.
