摘要:
Laterally "floating" thermal spray gun traversing apparatus and system for laterally tracking a revolving casting belt being thermal spray coated for applying uniformly spaced passes of thermal spraying on the revolving casting belt regardless of any lateral (edgewise) movements of the casting belt in either direction and regardless of any chamber in the edge of the belt. The thermal spray gun is traversed by a leadscrew and an adjustable speed drive for the leadscrew, both the leadscrew and its adjustable drive being carried by a frame mounted on a carriage freely movable along a trackway extending parallel to the axis of the leadscrew. A roller senses the lateral position of the edge of the revolving belt, and the carriage is moved by a source of motive power responsive to the sensed lateral position of the belt for causing the carriage together with the frame, leadscrew and leadscrew drive automatically to track the belt. This source of motive power is shown as a spring acting in a direction for urging the roller into contact with the edge of the revolving belt.
摘要:
A tieless bracing arrangement is provided for rigidly supporting the winding end turns of a dynamoelectric machine in relatively rigid operating position. The bracing arrangement is characterized by including an expandable annulus having a spreader that is operable in conjunction with a plurality of slidably mounted dowels to selectively hold the annulus open while it is positioned adjacent to the machine end turns and then to compress the annulus tightly against the end turns to secure them in operating position.
