R Series Helical Gearbox

The R series helical gearbox represents the standard for efficiency in industrial power transmission. Using precision helical gearing, it achieves efficiency levels unmatched by worm gear designs, making it the preferred choice for continuous-duty applications. ## Helical Gear Advantages Unlike worm gearboxes that rely on sliding contact, helical gears mesh with rolling contact, dramatically reducing friction losses. This means less heat generation, lower energy consumption, and the ability to handle higher power densities in a given frame size. Each gear is manufactured from high-grade alloy steel (20CrMnTi), case-hardened to HRC 58-62, and profile-ground to DIN 5 precision. ## Modular Construction The R series follows a modular design philosophy, allowing us to combine standard components into thousands of configurations. Common add-ons include: - Input flange adapters for IEC/NEMA motors - Solid shaft, hollow shaft, or shrink disc output - Backstop devices - Torque arms - Oil expansion tanks ## Typical Applications R series helical gearboxes excel in: - **Pump Drives** — Continuous operation with minimal maintenance - **Agitators & Mixers** — High torque at low speeds for chemical and food processing - **Crane Travel Drives** — Reliable performance under frequent starts and stops - **Extruders** — Handles high axial and radial loads
