· Small deformation of tooth profile, with the measured line and the reference line basically overlapped · Large deformation of tooth profile, with large deviation between the measured line and the reference line Since length control accuracy is lower than pitch accuracy, there is no
guarantee that an effective tooth can be formed for use when directly

Feature 1: The transmission and conveyance structure of gears and racks is
Judgment Result Judgment Result integrated, achieving n times the distance of the cylinder stroke.
Feature 2: The stroke can be converted to n times the original value by setting
· Accuracy grade compliant with New JIS Class 8/GB Class 8 standards · Accuracy grade not compliant with New JIS Class 8/GB Class 8 standards the ratio of small to large gear to 1:n.
· Design accuracy guaranteed, low vibration and noise, long service life · Poor engagement accuracy, low transmission accuracy, prone to vibration, large noise, short service life Feature 3: Force deviation can be eliminated by mounting gears on movable
base side in the center line of the cylinder and then mounting
* Generic products on the market are similar products randomly purchased by MISUMI from online or offline markets gears on fixed rack side evenly to the left and right.
* The test data are obtained through testing by MISUMI, which are for reference only Feature 4: The position of rack and gear can be adjusted by mounting lower
