Apex Dynamics is extending range of flange gearboxes
Common applications that use this mounting method are delta robots, stroke tables and rack systems, but also less accurate applications such as AGV drives. And with 5 series the customer can always select the optimal gearbox, for example the backlash, straight or right-angle, hollow shaft, curvic plate pinion, stainless steel, steel or aluminum, ratio and dynamic behaviour.
We will explain all the advantages individually per series. If you have any questions after that, we will gladly help you personally.
Benefits of mounting a gearbox with flange
Mounting on a flange instead of on a shaft has a number of advantages:
- Higher torques, often the shaft – especially the keyway – is the limiting factor.
- Higher bending moments and radial forces due to the generally larger bearings.
- Compact construction, because there is no output shaft.
- Form closed mounting instead of force closed mounting (shaft with clamping hub).
Application for a gearbox with output flange
The gearboxes with outout flange are often used in high-precision applications, such as:
- Robotics, for example Delta-robots.
- Takt tables, to make very accurate steps. For example, in filling installations.
- Rack systems, in use with a pinion. For example in laser cutting machines.
But also in less accurate applications, such as driving an AGV.
ISO 9404 guarantees interchangeability of the mechanical interface of the gearbox
The ISO 9404 standard defines the main dimensions, designation and marking for a circular plate as a mechanical interface. It is intended to ensure that the orientation of hand-mounted end effectors is exchanged. This global standard was established by ISO in 1996 and the last modification dates from 2004.
Low backlash gearboxes with ISO 9404 output flange
Because we have 5 different gearboxes with an output flange, you’ll find a short overview below so you can make the right choice faster:
