What are the working surface principles of Jiangxi precision gear runout instrument?

Precision gear runout meter
This instrument can measure the ring gear radial runout and end face runout of external gears and cylindrical gears, bevel gears, worm gears and worms with central holes and shafts (the tested gear does not have a shaft) , users can make their own mandrel with a hollow center). Product Details The radial runout and end face runout of the ring gear are measured (if the tested gear does not have a shaft, the user can make a self-made mandrel with a hollow center). This instrument can also measure the radial runout and end face selection of cylinders and cones with central holes.
Working principle of precision gear runout meter:
The radial runout Δr of the ring gear is the maximum variation of the side head relative to the gear line. For this purpose, the ring gear runout is checked using a measuring head with the original rack tooth profile. During inspection, the gear under inspection is fixed between the two thimbles of the instrument. The maximum variation of the original gear axis is △r.
