The BGM160BPE Goniometer features a worm mounted rotary encoder for improved accuracy and repeatability. The encoder also provides a method for detecting motor stalling, an important feature for applications with high loads or torques. The BPE full-step version with a reduction gear provides a higher torque and is recommended for high inertia payloads. BG Series goniometric cradles rotate on a transverse axis above the platform. Compared to full 360 ° rotation stages, they offer maximum free access to the rotating part and allow construction of very compact multi-axis rotation assemblies. BG cradles are designed so that orthogonal mounting of two adjacent-size cradles (e.g., BGS50 and BGS80) provides two perpendicular rotational axes intersecting at about the same point in space. Mounting a rotation stage under the assembly adds a third orthogonal rotation axis through the same point. Precision rotation is ensured by a precision ground, hardened worm gear drive. Single row ball bearings and precision ground tool-steel races ensure smooth rotation with minimal wobble and eccentricity. A home switch, conveniently located at the center of travel, facilitates the return of the platform to a level position.
Precision Multi-Axis Assemblies
BG goniometers are designed so that two adjacent-sized models can be directly mounted orthogonally to each other (for example, BGS80 with BGM120) to pivot about the same point in space. The direct mounting capability saves set-up time, design time, and adapter plate costs. For additional rotation axes, a rotation stage can be mounted under the assembly or on the top BG platform. The video demonstrates an open access, multi-axis tip, tilt and rotation assembly with two BG goniometers and two rotation stages.
Open Rotation Platform
The BG series stages provide up to ±45° of transverse axis rotation enforced with mechanical limit switches. The stage is designed for maximum free access to the rotating platform, allowing for simplified stacking and mounting.
Precision Worm Gear Drive
Precise rotation is ensured by a precision ground, hardened worm gear drive. In addition to being non-backdrivable, the worm gear drive's advantages include higher MIM, repeatability, and overall accuracy.
Ball Bearings with Tool-Steel Races
Single-row ball bearings and precision-ground, hardened tool-steel races ensure smooth rotation with minimal wobble and eccentricity. This allows for higher load capacities, stiffness, and stability.
