VRT Torque + System
We offer a comprehensive lineup of rack and pinion drive systems with exceptional accuracy, system rigidity, feed forces, torque density and efficiency. Each component of the system—gearbox, rack and pinion—is optimized to meet these demands. Although we focus on highly dynamic applications, we also offer more cost-effective options for less challenging axes.
Helical and straight racks are both available, from module 1.5 to module 12, with quality levels from 5 to 10 and lengths up to 3000mm. Our core products are induction hardened and ground, but we can offer a variety of heat treatment and surface finish options. Pinions are offered for keyed shaft or ISO9409-1-A mounting interfaces.
VRT Rack and Pinion System
- Maximum performance system with feed forces up to 29,463N
- Maximum requirements for linear stiffness, rigidity and torque density
- Gearbox frame sizes 090-200mm. Oversized tapered roller bearings for extreme radial and axial forces
- Quality 6 rack in 1m lengths. ± 0.035 total pitch error. Induction hardened and ground
- Compact ISO 9409 Flange connection with small pinion. Allows reduction in gearbox frame size and ratio
- Fit for high end machine tool applications such as portal milling machines, turning machines and measurement systems
