Cardan Shaft – Sleeve and Ferrule Stepper

Interactive animation of a Universal Joint, sliding along a hypothetical axis, demonstrating how a Glove and a Sliding Pointer work to change the length of a Cardan Shaft.

Cardan Shaft – Sleeve and Ferrule Stepper

The ferrule is sliding with an axis parallel to the lengthwise ridges. The glove has the same striae inside. This combination allows the grooves to transmit the turning motion of the shaft and sliding in one another to change the length of the Cardan shaft.

Simply put, the Cardan shaft acts as the hypotenuse of a right triangle. However, the legs of the triangle can vary in size. This feature forces the changing of the angles and the variation of the length of the hypotenuse. The glove set – ferrule Stepper is an elegant solution that accommodates the change in length of the cardan shaft when needed.

In this animation: the sleeve is transparent to allow visualization of the movement of the ferrule sliding inside; to improve slip view of the ferrule sleeve maximum angles are exaggerated.

Tips:

– There is a button to pause the animation for easy viewing;

– Interactive arrows allow restart animation;

– The smaller arrows allow smooth positioning in a certain position;
