The Drum Gear Coupling is a specially designed advanced Gear Coupling. Its outer teeth are made into a sphere, with the center of the sphere on the axis of the gear. The teeth clearance is slightly larger than the general products and can transfer a greater torque and allow greater angular displacement, enjoying excellent performance and longer life.

ROD Curved-tooth Gear Coupling is one of the transmission products with core technology independently developed by Rokee and has established and reported corporate technical standards in the country. By combining with the standard coupling technology of advanced countries such as Japan and Germany, we optimized many detailed dimensions, and adopted the toothed design with a large pressure angle and short shaft design for the shaft hole, which reduces the length-diameter ratio, and has a more compact structure and excellent speed performance.

The bolts of similar types are standardized and the parts are universal. Compared with the national standard couplings, our Toothed Couplings can transfer more torque, with greatly reduced mass and small moment of inertia. It meets the European explosion-proof requirements and the comprehensive performance is greatly advanced. We highly recommend you to choose our Crown Gear Couplings for better transmission performance.

Flexible Couplings are one of the major types of couplings. They find use to connect two shafts, end-to-end in the same line to transmit power that is torque from one shaft to another, thereby causing both to rotate in unison, at the same rpm.

The purpose of a Elastic Coupling is to transmit torque from one piece of rotating equipment to another, while accepting at the same time a small amount of misalignment. Flexible coupling misalignment is expressed, as an order of magnitude, in thousandths of an inch. Actual misalignment, expressed in coupling terms, is angular in nature and expressed in angular units, that is, degrees. How much misalignment is a function of the coupling type and installation. An installation variable is the equipment movement due to the temperature changes taking place in the machines as they go from the non-operating state to operation. Some angular values will be used in the discussion of the various types, but, again, these are for reference only. Each application must be reviewed using the type of coupling selected and the specific design proposed by the vendor.

The pin and bush couplings accept parallel, angular and axial misalignment and can provide considerable torsional flexibility. The flexible pin gear coupling is designed with non-metallic flexible pin, two toothed semi-couplings and a toothed sleeve ring with an outer ring. It uses non-metallic flexible deformation to transfer torque and cushion shock and compensate angular displacement.

The flexible pin coupling is a basic transmission parts that has simple structure, needs no lubrication, and is easy to manufacture, install and disassemble the flexible pin. It uses two semi-couplings with flange holes and a non-metallic flexible pin for crane to transmit torque, suitable for low-to-medium speed and low-to-medium torque occasions.

The design of the elastic sleeve pin coupling is simple and clever in design and has wide applicability. It uses the pin with elastic sleeve to connect two semi-couplings with pin holes to realize torque transmission and larger angular compensation. At the same time, it has good shock absorption and buffering performance, which can be used in high-speed occasions without lubrication and requiring easy pin sleeve replacement.
