1 Scope

This procedure applies to the first verification and subsequent verification of the gear standard involute model (rb ≤.200mm).

2 Overview

2.1 Gear involute model works Gear standard involute model (hereinafter referred to as model) is used for tooth shape measuring instrument, involute measuring instrument, gear measurement Verification, calibration, and adjustment of involute parameters such as measuring machine and gear measuring center (the above measuring equipment are referred to as instruments) And standard measuring instruments for acceptance. It is determined by comparing the involute on the working surface with the involute formed by the instrument. Instrument indication error. When using the coordinate measuring machine to measure the product gear involute parameters, the template should also be used to calibrate its indications. value. 2.2 Template accuracy level The model is divided into first-class model and second-class model according to its manufacturing tolerance and measurement uncertainty. Both models can be called standard Standard sample. 2.3 The role of the template 2.3.1 The first-class template can be used to verify the second-class template for value transfer. 2.3.2 Both the first and second samples can be used to calibrate the instrument values, resulting in corrections. Checking product teeth When the wheel is used, the instrument should be added with the correction value. 2.3.3 Instruments for measuring 3~4 gears, the indication error is verified by the first-class model, and the teeth of 5th grade and 5th grade are measured. For the instrument of the wheel, the indication error is checked by the second-class model. When characterizing gear instruments, two different base circle radii should be used The samples are separately performed, and the difference between the two plates is at least 80 mm. The maximum difference of the base circle radius rb is used to determine the involute of the instrument. Indication error. 2.4 Common sample size See Table 1 for other sizes.
