Superclasses: simscape.multibody.Joint

Construct bearing joint

Description

Use an object of the simscape.multibody.BearingJoint class to construct a bearing joint. A bearing joint models a compliant bearing that supports a spinning shaft. The bearing can translate along the shaft and allows the rotation about an axis that may not be aligned with the shaft.

A BearingJoint object models a transformation of the follower frame with respect to the base frame. The transformation contains a translation and a 3-D rotation. The translation is along the z-axis of the base frame. Like the simscape.multibody.GimbalJoint object, the BearingJoint object has three sequential rotations to achieve a 3-D rotation, as shown in the image.

Joint Transformation Sequence of Bearing Joint

The properties of the BearingJoint object contain one simscape.multibody.PrismaticPrimitive object and three simscape.multibody.RevolutePrimitive objects.

Revolute primitive about the y-axis of the follower frame, returned as a simscape.multibody.RevolutePrimitive object. The revolute primitive corresponds to the rotation of the follower frame with respect to the base frame about the y-axis of the follower frame generated after the rotation about the x-axis.
