A provider of high-precision drives and systems has introduced a series of planetary gearheads. The GP 26 A gearheads close the gap that previously existed between the 22- and 32-mm diameter products in the range of power-optimised gearheads, according to the company. Particularly significant improvements over the previous generation are the higher permissible loads.
The following features are responsible for the power increase, according to the company: the integration of robust, preloaded ball bearings; optimised gearhead geometry; high permissible motor speed; and optimised dimensions of the output shaft. This gearhead is part of a modular system and is available in one-stage to three-stage versions, with a total of nine different reduction ratios, from 5.2:1 up to 236:1. The maximum continuous torque of the one-stage version is 0.75 Nm; the three-stage version is 4.5 Nm. The short-term torques are 1.1 Nm and 6.2 Nm, respectively. Thanks to the preloaded ball bearings, the tempered, rust-free output shaft has no axial play.
Within the maxon motor modular system, the new GP 26 A gearhead can be combined with five different motor types. For the control functions, various 1- and 4-quadrant controllers, as well as positioning controllers, are available.
