Integrated error measuring technology and method thereof of gear pair

Abstract

The invention originally provides a new novel error index (the integrated error of a gear pair) capable of replacing the driving error and a measuring method thereof. On the basis of the integrated error measuring technology of the gear pair and by adopting an indirect measurement method, all error information on each conjugate gear pair of the gear pair and error data on a complete meshed period can be obtained, so that the measuring method not only solves the problems in the measurement of the driving error, but also allows the integrated gear error theory of the state to be further popularized and applied. An external envelope line of the measured integrated error curve of the gear pair is a drive error curve; compared with the drive error, the integrated error of the gear pair contains more comprehensive and complete error information, thereby not only reflecting the amplitude of mutual action of the errors of a driving wheel and a driven wheel, but also reflecting the form and concrete process of the error action. The invention not only can be used for the research of the meshed process of the gear and the evaluation of the drive quality, but also can be used for error tracing and process analysis and or can also be used for researching how the errors of two gear teeth which simultaneously participate in the meshing in a two-meshed area mutually influences the driving quality.

Description

technical field [0001] The invention relates to a new gear pair error measurement technology and measurement method, belonging to the technical fields of precision testing technology, instruments and mechanical transmission. Background technique [0002] The final transmission quality of the transmission chain depends on the comprehensive transmission accuracy of the entire gear pair. Only by controlling the manufacturing accuracy of a single gear may not be able to achieve high-quality transmission. The transmission error reflects the comprehensive transmission accuracy of the gear pair. It refers to the difference between the actual occupied position of the driven wheel and the theoretical position for any given position of the driving wheel, and reflects the comprehensive effect of the individual deviations of all the gears in the gear pair. Effect. [0003] The measurement of the transmission error generally adopts the single-sided meshing measurement method. During me...

Problems solved by technology

[0005] 2. Transmission error is difficult to use for error traceability

[0006] 3. Gear pairs with the same transmission error may not necessarily cause the same vibration and noise

The publication number is 1483994, a gear error measurement method and its device, and the patent number is ZL 2008 1 0115726.4, a gear overall error measurement device and method. They all propose different measurement methods for the gear overall error, but they all need to use special standards The measuring element engages in meshing

However, this idea of ​​using special standard components to participate in meshing cannot be used when measuring the error of a gear pair composed of two error gears.
