[Blank] double gear processing methods
Gear blank machining double gear tooth surface before processing, plays an important role in the whole process of the double gear. Because the tooth surface processing and testing benchmarks used must be working out at this stage, while a larger share of the gear blank machining man-hour ratio, in terms of improved productivity, quality assurance process or from the double gear, must pay attention to rough machining gear .
The technical requirements of the Department of gear pattern in double, if the provisions in the pitch circle selected thinning tooth thickness backlash determined, should pay attention to the addendum circle of accuracy, because the tooth thickness detection is an addendum circle to measure the baseline. Addendum circle precision is too low, it will bring the measured tooth thickness can not accurately reflect the size of the backlash, so in this process should note the following three issues:
1) When the addendum circle as a measuring reference, should strictly control the addendum circle dimensional accuracy;
2) to ensure the vertical positioning of the positioning holes or cylindrical face and between;
3) to improve manufacturing precision gear bore, reducing the gap with the mandrel fixture.
