Monitoring the kinematic accuracy of precision gear wheels

Conclusions

• 1. The increasing importance of kinematic monitoring has made it important to unify measurements in kinematic monitoring.

• 2. To provide maximum agreement between monitoring and working conditions, it is best to perform acceptance monitoring of gear wheels by kinematic methods rather than geometrical ones [3].

• 3. Monitoring the kinematic accuracy of a gear wheel is a particular form of monitoring related to linear and angular measurements but not reducible to them.

• 4. Kinematic monitoring of gear wheels, pinions, and tooth-cutting machines influences the accuracy of gear wheels in three ways: by the provision of acceptance monitoring with instruments for single-profile checking, by provision of prophylactic monitoring of gear-cutting machines and tools, and by the provision of the necessary volume of information on the stability of the technological process.

• 5. The use of CMM for monitoring gear wheels, including conical ones with any tooth shape, considerably improves the informativeness of the results by virtue of the use of the computer memory CMM for forecasting the behavior of a gear wheel under working conditions.

• 6. Metrological stability in the production of precision gear wheels is thus dependent not only on the quality of the technological equipment but also to a considerable extent on the metrological support to production.

• 7. These deficiencies and bottlenecks in metrological support to the production of precision gear wheels can be eliminated by developing a system for transmitting the unit of planar angle (as a measure of angular displacement) to kinematic monitoring, with upgrading of the methods and means of checking kinematic monitors and instruments for single-profile monitoring, as well as expansion of the range of instruments for all-round monitoring of gear wheels.
