Abstract
A device and method for axially aligning a rotary head assembly. The rotary head assembly includes a rotary head and an axial alignment assembly. The axial alignment assembly includes a guide plate means fixed to the rotary head. The guide plate means has a pair of opposing surfaces extending radially from the shaft. The axial alignment assembly also includes a carrier means with a yoke attached thereto, and an alignment element attached to the yoke. The alignment element has a pair of opposing wear surfaces for contact with the opposing surfaces of the guide plate means. The alignment element also includes an axial pressure exerting means for exerting pressure axially on each wear surface so that there is contact between the opposing surfaces of the guide plate means and the corresponding wear surfaces. Pressure is exerted on the wear surface in the direction toward the corresponding face of the guide plate means to maintain axial alignment of the head assembly as it rotates.
