摘要： In apparatus for testing for single-flank total composite error in a bevel gearwheel transmission at a required center spacing and in which the gearwheels to be tested are coupled each to a respective cylindrical measuring disc, and two straight edges roll upon said measuring discs without sliding thereon, one of said straightedges acting upon indicating means, the measuring discs being constructed as base circle discs of constant diameter independently of the transmission ratio of the gearwheels to be tested, and the longitudinal motions of the two straightedges being matched to each other by way of a control bar which is angularly adjustable in accordance with the transmission ratio of the gearwheels, the control bar being mounted on a slide which carries the two straightedges, the other said straightedge having a body rectilinearly guided on said control bar, the axes of the two base circle discs are disposed perpendicularly to each other.

摘要： A TESTING APPARATUS FOR TOTAL SINGLE-FLANK COMPOSITE ERRORS IN CYLINDRICAL GEARS BY INDICATING DEVIATION FROM THE UNIFORM TRANSMISSION OF THE ANGULAR MOTION FROM A FIRST GEAR OF A PAIR OF INTERMESHING GEARS TO THE SECOND GEAR. THE FIRST GEAR IS ROTATED BY A FIRST DISK IN ROLLING CONTACT WITH A FIRST STRAIGHT EDGE. THIS STRAIGHT EDGE IS TRANSLATIONALLY DRIVEN BY A SLIDE. THE SLIDE HAS AN ANGULARLY SETTABLE ARRANGEMENT TO DETERMINE TO RATIO OF THE AMOUNT OF MOVEMENT OF THE SLIDE TO THE AMOUNT OF MOVEMENT THE FIRST STRAIGHT EDGE WHICH IN TURN ROTATES THE FIRST DISK. THE SECOND GEAR, IN MESH WITH THE FIRST GEAR, IS CAUSED TO ROTATE BY THIS MESHING. COAXIAL WITH THE SECOND GEAR IS A SECOND DISK WHICH IS FREE TO ROTATE WITH RESPECT TO THE SECOND GEAR. THE SECOND DISK IS IN ROLLING CONTACT WITH A SECOND STRAIGHT-EDGE WHICH SECOND STRAIGHT-EDGE IS TRANSLATIONALLY DRIVEN BY THE SAME SLIDE THAT DRIVES THE FIRST STRAIGHT EDGE. MEASURING APPARATUS MEASURES THE ROTATION OF THE SECOND GEAR WITH RESPECT TO THE SECOND DISK. THE ANGULARLY ADJUSTABLE ARRANGEMENT IS SET IN ACCORDANCE WITH THE GEAR TOOTH RATIO OF THE MESHED GEARS SO THAT IF THE GEARS HAD NO ERRORS THE

MEASURING APPARATUS WOULD SENSE NO MOTION OF THE SECON DISK RELATIVE TO THE SECOND GEAR. ERRORS IN THE GEARS WILL RESULT IN THE MEASURING APPARATUS SENSING THE RELATIVE MOTION OF THE SECOND GEAR TO THE SECOND DISK.
