Mechanism
The RollerDrive mechanism mainly consists of an input shaft and output turret with embedded roller followers. A cross-roller bearing works to support the output turret with minimal run out.
Preloaded roller followers contact the input rib surfaces with a wedge-shaped cross section. This can be adjusted my moving the input axis, which in turn eliminates backlash completely – meaning superior precision and rigor for CW and CCW rotation; as displayed in the diagram to the right.
Even with preload and zero-backlash, the needle bearing type roller followers transmit power by rolling rather than sliding. This allows the RollerDrive to achieve an outstanding efficiency of 90% or more. RollerDrive guarantees a lifetime of wear-free durability.
All parts are made from only qualified alloy steels; machined and ground with our ultra-precision machining system.
Perpetual Precision
The unique mechanism of the RollerDrive allows the RollerDrive CNC to withstand years of operation without compromised performance. This means no internal part wear and no loss of precision. Regular calibration and readjustment is unnecessary when you choose the RollerDrive CNC.
