Multi Axis Belt Driven Modular Linear Actuators
Belt driven modular linear actuators have a distinct advantage due to their ability to be manufactured in virtually any length. Multi axis belt driven modular actuators have the advantage of simplicity. They are pre-engineered to provide by-directional movement across two or more planes.
The belts are made of a high tension steel material that only requires a single adjustment after initial use. No further tensioning is required. The pulleys have maintenance free ball bearings. Belt tension can be readjusted by a simple screw adjustment device in the carriage.
External Belt Driven
The carriage, using an external linear belt, is driven along an external linear guide rods and ball bearings that can be adjusted to remove lash. This provides a low friction smooth linear movement.
The carriage is driven by an external linear belt that can be adjusted to reduce lash and is driven along the external roller bearings. The pulleys have maintenance-free ball bearings. Belt tension can be readjusted by a simple screw adjustment device in the carriage.
The ELZU external belt driven actuator consists of two Y-axes and single X-axis, driven by one rotating belt. This belt runs around different deflection pulleys. Positioning is achieved by two motors. The coordinate is diagonal to the deflection points of the Y-axis. Advantage: A smaller amount of inertia is needed, thus enabling high accelerations to be achieved.
