Dual cable drive rolling arc gimbal

摘要

A gimbal assembly includes an outer arcuate yoke gimbal member mounted on rollers to rotate about its axis and an inner gimbal member includes a platform pivotally mounted in the yoke to rotate about a second axis. Two drive motors are separately and independently connected through independent cable drive assemblies to separate ones of the inner and outer gimbal members and functions either individually or together to rotate the gimbal members selectively or both together in a combination of motion. In one form, the two drive motors are co-axially mounted in the base of the gimbal assembly. In another form the gimbal drive motors are co-axially mounted with the outer housing of one motor forming the drive pulley for the other drive assembly. In another arrangement the motors are disposed on adjacent parallel axes with one drive motor for the inner gimbal having co-axially disposed drive pulleys for the drive cable.
