Innovative bushing system as an alternative to conventional clamping connections

Innovative bushing system as an alternative to conventional locking devices

The specific application of connecting the hollow shafts to the system shafts in the case of high-torque gearboxes of a leading manufacturer posed an innovative and complex key requirement: Providing for the flexible coverage of solid shafts in different metric and inch-based dimensions via one hollow shaft system without restricting the functionality and performance range of the transmission in comparison to conventional shrink disc connections. For this purpose, RINGFEDER® designed a special modular bushing system together with the customer, which allows for the generation of a frictional clamping connection of shafts with a range of different rated diameters and even less narrowly tolerated surface qualities – and all this providing easy and quick options for assembly and disassembly. The RINGFEDER® shrink discs also used for this system variant are manufactured of high-strength forged rings, in this way obtain maximum attain durability and, when dimensioned optimally, work in an absolutely wear-free and maintenance-free fashion.
