Grooved Sleeves(Shell)
Split-sleeve consists of a pair of outer shells that are bolted or welded onto a smooth drum. We can manufacture spiral groove and lebus groove.
The split-sleeve depends on the drum’s size, wire rope diameter and length. The sleeve is composed of a sleeve cut in half, which can be fixed to a smooth drum by welding or bolted fastening. If we want to make a sleeve, we need only the drum size , wire rope size , and the number of winding layers, We can customize production based on this data. The scope of application is the same as that of lebus drum.
Successful cases
Our production of lebus grooved drum, and winch rope groove plate assembly, now widely used in petroleum machinery, mining machinery, ships, ports, lifting machinery, lifting machinery, etc., and with daqing oilfield, shengli oilfield, dagang oilfield, zhongyuan oilfield, liaohe oilfield oilfield, nanyang oil factory, big companies such as sany, established a long-term, stable relations of cooperation, Products are also exported to the United States, Canada, Brazil and so on. Our factory can design and manufacture various specifications of folding rope groove tube, rope groove plate and winch according to the requirements of users, but also can provide on-site installation.
What is the welding process of steel sheet drum group?
Adopting plate blanking roll cylinder and weld longitudinal welds, checking longitudinal welds and geometric dimensions of cylinder (diameter, length, inner diameter ellipticity tolerance, etc.). For large diameter cylinder, adding welding process reinforcement and machining annular groove of cylinder. There are requirements for the process of roughing the cylinder outside the circle to process the outer circle, cylinder length welding (namely ring seam welding). For the two ends of the cylinder need to add welding process reinforcement according to the process regulations, and check the quality of ring welding and machining allowance, cylinder length processing and both ends of the stop or groove processing and welding cylinder end flange plate, shaft, inner support ring, etc.
