Accessory for measuring geometry of ICE crankshaft journals.

Design Part

Accessory is intended for measurement of geometry of crankshaft journals of internal combustion engine.

Axle (4) is screwed into base (2) by means of screw (3). Rack mechanism (1) consists of: housing (5), grip (15), axle (8), clamp (13) and adjusting screw (9)

After installation of the controlled part on the mandrel (setting pin), the indicator (17) is supplied to the part. The indicator rack is rotated so that the indicator (17) fixed on it assumes horizontal position. The indicator must touch the surface of the monitored part and then be fixed with a clamping screw (12).

Indicator tip is installed on side surface of neck, and indicator is set to zero. In case of deviation from the roundness, the indicator arrow receives the angular movement indicated by the indicator.

The accessory is ready to take readings.

To remove the geometry of the crankshaft journals, use the wheel to slowly rotate the monitored part.

The necessary readings were taken.
