With the newly designed SMS KL helical bevel gear unit available in sizes 1 and 2, STOBER now has compact right-angle drives to meet the requirements of the packaging machine manufacturers for modern, cost effective, space-saving Geared unit. The key to this remarkable reduction in size and increase in performance is down to a newly designed 2-stage gear set geometry.

The housing dimensions of the two gear unit sizes illustrate the new shape factor. In the KL1 version the length is 113.5 mm, the width 81 mm and the depth 90 mm; this represents a volume of only 0.83 litres. The KL2 is 143.5 mm long, 98 mm wide and 108 mm deep, which makes its volume only 1.52 litres. This compact housing also gives a significant weight reduction which is an advantage for the drive dynamics, particularly on ‘travelling drives’.

The new gear unit design is not just outstanding in terms of its dimensions. It also passes the fitness test for applications with very high speeds, because input speeds of up to 6000 rpm are possible in cyclic operation. The torque range is up to 65 Nm.

The highly stiff and compact construction requires no offset, which simplifies design of the machines and systems. On the output side, the new right-angle geared motors offer various options for output shafts and mounting methods. A further option is that motors from other suppliers can be fitted using an adapter with a backlash-free plug-in connector and thermal length compensation.
Both sizes are available in all option formats as of now.
 

Precision Rack and Pinion drives

Due to the moment loads created from Rack and Pinion mechanisms this typically determines the size of specified Gearbox with utilisation of the gearbox torque as low as 40%
STOBER now overcomes this with the ZTRS range of super compact and highly efficient Rack and Pinion drives – they have an integral output bearing housing with a highly stiff supporting arm for the pinion. This design relieves the tilting moments on the gearbox, so making it possible to base the drive design on Actual driving torque requirements.
