The principle of this device is to mount a standard gear on a fixed vertical spindle and the gear to be tested on another similar spindle mounted on a similar spindle mounted on a sliding carriage, maintaining the gears in mesh by spring pressure. Movements of the sliding carriage as the gears are rotated and indicated by a dial indicator, and these variations are a measure of any irregularities in the gear under test , alternatively a recorder can be fitted , in the form of a waxed circular chart and records made of the gear variation in accuracy of mesh.
The gears are mounted on the two mandrels , so that they are free to rotate without measurable clearance. The left spindle can be moved along the table and clamped in any desired position. The right mandrel slide is free to move, running on steel balls , against spring pressure and it has a limited movement. The two mandrels can be adjusted so that their axial distance is equal to the designed gear center distance.
When the waxed paper recorder is fitted, the chart makes a revolution for each one of the gears mounted on the sliding carriage. As the chart moves and rotates, the line traced records the movements of floating carriage. A circle is drawn at the same time as the record as shown in figure 12.
