Attachment Points

Attachment points on spider assemblies are critical structural interfaces that facilitate the connection between the central hub and radial arms or external components in rotating systems. These points are engineered to withstand dynamic loads, torsional stresses, and vibrational forces while maintaining precise alignment and mechanical integrity. They typically feature standardized bolt patterns, keyways, or splined connections to ensure reliable torque transmission and prevent relative movement between connected parts.

Attachment points function by providing geometrically constrained interfaces that distribute mechanical loads evenly across the spider assembly. They utilize interference fits, threaded fasteners, or positive locking mechanisms to create rigid connections that maintain concentricity and balance during operation. The design ensures that centrifugal forces, torque, and bending moments are transferred efficiently without creating stress concentrations that could lead to fatigue failure.
