Performance right angle gearboxesThe range of Vogel bevel helical gearboxes available through Techdrives suit demanding drive applications because of their small size and high efficiency. The KS range also has very low backlash and inertia, suiting it to servo motors. With eight sizes and rated torques from 100 to 12800Nm, these gearboxes are attractive alternative to other right angled designs that use worm and helical worm technology, giving superior performance and efficiency.
The Vogel KS is a two stage gearbox. The input stage is a bevel gearset with spiral cut gearing that achieves a large contact engagement allowing high torques to be transmitted in a small size. The output stage is a helical gearset that is hardened and ground. Ratios available are from 6.0 to 48.0 and running efficiencies are in the range 90 to 96% depending on the ratio. Precision manufacture of the gears results in angular backlash below 10 arcmins and on request this can be further reduced to below 4 arcmins.
A modular casing design allows free shaft or motor flange inputs. Flanges are to IEC standard dimensions or on request they can be customised to suit servo motors using a shrink disc shaft connection that is backlash free. Output can be either male single shaft, double shaft or hollow shaft with or without shrink disc. Where an application calls for a servo geared motor with right angle configuration, these gearboxes are ideal. High torque capacity allows 250% emergency stop torques, compact dimensions, low inertias and the low backlash allows precision positioning.
The key feature of the Vogel KS bevel helical gearboxes is the combination of precision bevel and helical gearsets. This gives a high power density, but low inertias and low backlash that particularly suits servo and reversing drives. The high efficiency is close to the levels of in-line helical gearboxes and is outstanding for a right angled design.
