Rokee® Customized Large Main Transmission Cardan Shaft for Customers, Rokee® is a well-known high-quality supplier of couplings and technical services in China.
As the core component of heavy machinery transmission systems, large main drive universal shafts play a crucial role in modern industrial production. This type of universal joint is designed to meet the requirements of high torque, high speed, and complex working conditions, and is widely used in heavy equipment fields such as metallurgical rolling mills, mining machinery, ship propulsion, and engineering vehicles.
The large main transmission universal joint is mainly composed of the following core components:
Universal joint assembly: Adopting a cross axis or ball cage design, the cross axis type is usually composed of alloy steel forged cross axis, needle roller bearings, and sealing components, allowing an angular deflection of 15 ° -25 ° between the two axes
Transmission shaft tube: High strength alloy steel pipe fittings with a wall thickness of usually 20-50mm, precision cold drawn or hot-rolled, and surface shot peening strengthening treatment
Expansion spline sleeve: involute spline structure with module 6-12, sliding surface sprayed with wear-resistant coating, compensating axial displacement up to 300-800mm
Flange connection component: forged steel flange, bolt holes are precision bored to ensure docking accuracy
Its working principle is based on the principle of dual universal joint constant speed transmission, which achieves synchronous rotation of input and output shafts through phase compensation of two universal joints in the presence of axis deviation angle. When the active shaft rotates at a constant angular velocity, the intermediate shaft will experience periodic angular velocity fluctuations. However, by arranging the two universal joints in a reasonable manner so that the deflection planes coincide and the angles are equal, the final output shaft can achieve the same rotational speed as the input shaft.
