METHOD FOR ALIGNMENT OF ROTARY MATING SHAFTS AXES THAT MAKE COMPOSITE SHAFTING, RELATIVE TO AXIS OF DRIVE SHAFT OF BRAKING MACHINE OF MOTOR BENCH AND AXIS OF CRANKSHAFT OF TEST SUBJECT - INTERNAL COMBUSTION ENGINE (VERSIONS) Russian patent published in 2009 - IPC G01B11/27 G01M15/04 

FIELD: physics, measurement.

SUBSTANCE: method for alignment of rotary mating shafts axes that form composite shafting, relative to axis of drive shaft of braking machine of motor stand and axis of crankshaft of internal combustion engine (ICE), consists in control, installation and necessary adjustment of coaxiality in location of specified mating shafts of bench and ICE that is preset by field of permissible deviations by means of adjustment of spatial location of support elements of mechanical system of ICE fixation in bench. Light beam display screen is mounted between flange of drive shaft of braking machine of bench and flange of mating section of intermediate shaft of ICE bench support. In the opposite flange of drive shaft bracket is installed with holder, in which autonomous module of alignment laser device is mounted with source of laser radiation. Light beam of laser ray is directed and focused in direction of line trajectory. ICE crankshaft is forcedly and slowly rotated, trajectory line of focused light ray light beam is visually inspected, focused laser ray light beam motion trajectory is matched with trajectory line, or field of permissible deviations formed by two concentric circles, whenever trajectory line diverts moving light beam from trajectory of marked circle line, or outside the field of permissible deviations formed by two concentric circles - corresponding adjustment operations are performed for forced variation of ICE spatial location on motor test bench by means of preset spatial variation of support vertical stands location height, as well as bearing cross beams of ICE fixation system in bench to spatial position.

EFFECT: increased accuracy of technological operation of alignment of axes in mating shafts of composite shafting with further periodical technological operations for control of axes alignment preservation in preset limit allowances.
