Shaft Redesign – Alternative Solution Development
An alternative shaft assembly was developed to address the limitations of an underperforming existing design. The solution had to reconcile severe space constraints with high torque and RPM requirements, while accommodating continuous axial movement during operation.
To simplify maintenance, a quick release hub with telescoping feature was incorporated, utilising spring-loaded rings and a ball lock mechanism for secure yet rapid disassembly. A non-standard outer diameter was specified to fit heavy-duty full complement needle bearings, while improved seals were introduced to enhance lubricant retention and extend service intervals.
Additionally, a ball spline trial version was developed to counter wear on the existing spline shaft, providing a more durable solution for managing the application's continuous axial movement.
