DEVICE FOR CONTROL OF RADIAL RUNOUT OF CRANKSHAFT MAIN JOURNALS Russian patent published in 2022 - IPC G01B5/20 

FIELD: control and measuring equipment.

SUBSTANCE: invention relates to control and measuring equipment of machine-building and repair and maintenance enterprises, in particular for control of radial runout of crankshaft main journals. A device for control of radial runout of crankshaft main journals contains a frame, two roller prisms with an installed crankshaft, guide rollers for prisms, and an indicator on a stand, while it has a measuring plate located on the frame, a linear electric engine, a friction rubberized disc, a gearbox motor, a low plate installed on the frame, a pneumatic cylinder, while a stationary roller prism, the indicator on the stand, and guide rollers with a movable roller prism and the linear electric engine are located on the measuring plate, and the gearbox motor is located on the low plate, connected to the friction rubberized disc via a belt drive, wherein the pneumatic cylinder is installed between the low plate and the frame for provision of a possibility of rotation of the low plate.

EFFECT: reduction in time during reinstallation of prisms in case of measurement of different crankshafts, possibility of control of radial runout of any journals relatively to each other, and elimination of manual turnaround of the crankshaft, when measuring runout.
