New Compact Precision Gearboxes from Neugart: Drive Power in Frame Size 055

Neugart is responding to the trend towards ever more compact servo drives with three new precision planetary gearboxes in frame size 055: the new developments PSBN055, PSN055 and PSFN055 extend the Precision Line portfolio with smaller frame sizes.

The description of the frame size refers to the square dimension or centering collar diameter of the output flange, which in this case measures just 55 mm in width. Despite their compact dimensions, the gearboxes offer a high torque density and high precision in a very small installation space. This makes them suitable for electronically controlled servo drives of small handling units in packaging and many other machines.

All three new developments are available with 1 or 2 stages and with different ratios i=3 or i=4 to i=100. Despite all the similarities, they differ in key details that make them ideal for different areas of application. For example, the PSBN055 and PSN055 have an output shaft (either smooth or with feather key), a square type output flange and reinforced output bearings. In contrast, the PSFN055 is a gearbox with a flange output shaft in accordance with ISO 9409-1 (optionally with or without a flanged contact roller hole), whereby the round, extra-large flange is equipped with preloaded angular contact roller bearings
