1. Measurement of single geometric error of gears
This measurement technology mainly uses the method of geometric analysis measurement. Taking the gear as a complex geometric entity, on the established measurement coordinate system, the geometric deviation of the gear tooth surface can be measured according to the design geometric parameters. The main methods are discrete coordinate point measurement and continuous geometric trajectory point scanning. The error items measured by these two methods are the single geometric deviation of the gear, which is mainly formed by the tooth profile, tooth direction and tooth pitch.
2. Measurement technology of gear comprehensive error
This measurement method mainly adopts the meshing rolling measurement method, which takes the gear as the rotary motion transmission element, meshing and rolling with the measured gear under the theoretical installation center distance, and measuring the comprehensive deviation. This measurement method is divided into gear single-sided meshing measurement, used to detect the tangential comprehensive deviation of gears and single tooth tangential comprehensive deviation.
3. Gear integral error measurement technology
Based on the overall error theory, this measurement technology takes the gear as the geometric entity to realize the transmission function, or uses the coordinate geometric analysis method to measure the accuracy of other single geometry, integrates the "static" gear overall error curve according to the meshing sequence and position, or uses the special measuring gear according to the single-sided meshing comprehensive measurement method, and uses the rolling point scanning to measure it, Get the "motion" overall error curve of the gear.
4. On machine measurement technology of gears
This technology has developed rapidly in recent years. The gear is integrated into the machining machine tool. The gear cannot be disassembled after trial cutting. It needs to be measured on the machine tool immediately, and the machine tool parameters and adjustment and repair are carried out according to the measurement results. Using this measurement technology in forming gear grinding and gear grinding can effectively improve production efficiency and reduce costs.
5. Gear laser measurement technology
This technology refers to the laser technology that will be used in the measurement of the assembly size and shape position of gears, including laser length measurement system, laser measurement head system, laser holographic gear measurement system and so on.
