Overview

The assembly of the Rotary Actuator v2 consists of a concealed 10:1 flanged gearbox between two Vention compatible plates. The bottom mounting allows for any combination of Vention’s NEMA 34 stepper servo motors. With a 10:1 reduction present on the actuator, multiple levels of torque can be achieved. The bottom plate also features mounting holes that interface perfectly with Vention extrusions. The top plate features multiple countersunk and threaded holes for all your mounting purposes.

Applications

There are several application for 4th Axis Palletizer or a Rotary Inspection Station for Universal Robots.

Mounting Sensors

You can add home and end sensors to a rotary actuator, and they will work the same way as home and end sensors on a linear actuator.
A home position sensor enables repeatable motion: it provides a reference point to which the actuator can “zero.” Adding both home and end position sensors means that in addition to enabling repeatable motion, you can also limit the actuator’s travel.
The home and position sensors are both inductive proximity sensors (CE-SN-004-0003). They are each mounted to a block (MO-RM-002-0007), which is itself mounted to the rotary actuator with two M6 x 35-mm screws (HW-FN-005-1035).
The sensors are activated when they approach a trigger. Two triggers—one for each sensor—are typically mounted to the underside of the top plate. Each trigger is mounted through a slot, which allows its position to be fine-tuned, with two M4 x 8-mm screws (HW-FN-010-0008).
