The RAM 2-Speed spindle gearbox is designed to extend the constant power range of spindle drive motors and provide:
- High torque for hogging out steel or titanium
- High speed for finish machining aluminum.
The RAM (High Torque) two speed gearboxes are designed for in-line integration between a water cooled motor and a spindle inside of a machine-tool RAM as shown below:
This newest generation of 2-speed gearboxes improves torque density while decreasing the outside diameter and increasing the hollow bore diameter. Furthermore, it is a kit version that eliminates redundant bearings in the design and makes the entire system operate with lower temperature, vibration and noise levels.
This compact, light-weight design matches the latest spindle drive motor technology and offers:
- Hollow through bore to facilitate a draw bar and through spindle coolant
- Round Housing to fit inside of RAM bore and share motor coolant supply
- Remote hydraulic speed change compatible with CNC control
- Quiet minimum vibration operation to match spindle requirements
- Dry sump lubrication for minimum thermal expansion
