Rokee® Customized Gear Type Barrel Coupling for Customers, Rokee® is a well-known high-quality supplier of couplings and technical services in China.
The gear type barrel coupling is a special coupling designed specifically for the drum transmission of lifting equipment. It adopts a drum shaped tooth meshing structure to achieve high torque transmission and multi-directional compensation functions
Drum shaped tooth design
The curvature radius of the external tooth spherical surface is optimized to R300-R500mm, with a tooth side clearance of 1.3-1.5 times that of standard gears, allowing for axial compensation of ± 5mm, radial compensation of ± 3mm, and angular compensation of 1.5 °.
The typical model of DC series adopts 42CrMo alloy steel, with a tooth surface carburizing and quenching hardness of HRC58-62, and a fatigue life of over 10 ^ 7 cycles.Modular construction
Integrated brake disc (WGZ type), nylon inner gear sleeve (TGL type) and other variants, the WZL series ball joint design can absorb the impact vibration of the drum steel wire rope.Lubrication system
The high-pressure oil passage design achieves forced lubrication with thin oil, and the new graphene coating reduces the friction coefficient to 0.02, extending the maintenance cycle to 8000 hours.
Application in the field of lifting equipment
Bridge crane: Recommended DC03A type (torque 80kN · m), compensating for track installation deviation
Portal crane: WZL14 type with brake disc version is selected, with a response time of less than 0.1 seconds
Metallurgical crane: requires high temperature resistance (-20 ℃~200 ℃), GICLZ type equipped with copper based grease
Over the years, with excellent quality, we have been continuously providing many coupling products of various categories and uses complying with multiple standards and a full range of services, from the product selection to final installation and operation, for the industry fields of ferrous metallurgy, nuclear power, gas turbine, wind power, ropeway construction, lifting transportation, general equipment, etc. We strictly comply with quality system requirements and implement the whole process control to become a reliable and trustworthy partner of customers.
