Hollow shaft gearbox for direct main spindle drive attachment

ZF Friedrichshafen presents a new one Hollow shaft gear for Main spindle drives in front. The new Transmission The series with hollow shaft will initially start with the HWG 280 and 380 variants. They belong to the “Duoplan” model family and, according to the manufacturer, have many advantages over conventional two-speed manual transmissions.

By decoupling the Planetary gear set In direct gear (1: 1) at high speeds, the rotating masses are reduced. This results in short run-up times, a very low temperature development and very low vibration values ​​of less than 1 mm / s.

Hollow shaft gear for media feed-through

Components such as push rods for release units or Coolant be performed. The very low heat input through the rotating sealing surfaces is achieved due to the small shaft diameter.

Harmonic gears for industrial robots, cobots and handling

The gearbox is specially designed for direct attachment to Spindle and Motor designed (inline, RAM integration). This means that machines that were previously designed exclusively for direct drive can also be offered with gear options. Depending on the size, the gearbox with a hollow shaft reaches speeds of up to 18.000 rpm^-1. The processing options on the machine increase with the use of this hollow shaft gear and enable more flexible use.
