Heavy Duty Cardan Shaft
The heavy-duty cardan shaft is designed with a cross axis structure as the mainstream, consisting of a flange fork head, a cross axis assembly, a bearing sleeve, and a lubrication system. The core component of the heavy-duty universal joint, the cross shaft, achieves multi-directional freedom through needle roller bearings, allowing the two shafts to transmit torque within a range of 5 ° -45 ° angles. The typical workflow of a heavy-duty universal joint is as follows: the driving shaft drives the flange fork to rotate → the cross shaft decomposes the motion into two orthogonal planes of oscillation → the driven shaft flange receives and synthesizes the continuous rotary motion. This design can compensate for radial, axial, and angular deviations simultaneously.
Application scenarios of heavy-duty cardan shafts
Metallurgical industry: main drive for hot rolling mill, sector drive for continuous casting machine.
Mining machinery: ball mill transmission system, bucket wheel excavator rotary mechanism.
In actual selection, fatigue life verification should be carried out based on the dynamic load spectrum of specific equipment, and finite element analysis should be used to verify stress concentration areas if necessary.
