Control instrument

Gear gauge for worm wheel coupling.

The bench can move along two axes:

AXIS "X": horizontal

AXIS "Y": vertical

Axis X: an optical line with a reading sensitivity of 0.01mm is aligned on this axis with a centesimal comparator being fixed on to the control equipment support surface.
Two movements can therefore be performed along the X axis, namely:

• the carriage can be positioned by acting on the front flywheel, and
• the top surface can be released, thus permitting it to move independently of the support carriage.

The combination of these two movements permits to measure:

• mesh eccentricity
• tooth head
• tooth meshing clearance

Axis Y: a second optical line with a sensitivity of 0.01 mm is aligned on this axis. Movement of this axis permits to measure:

• displacement of the toothing axis
