Embodiment Construction

[0045] Attached below Image 6 , the present invention is further described:

[0046] Gear parameters: module: 5.5mm, number of teeth: 14, pressure angle 20°, helix angle 0°, addendum coefficient 0.8, superimposed first harmonic wavelength is 2.7061mm, amplitude is 5um, superimposed second harmonic wavelength It is 1.3531mm and the amplitude is 5um. The first harmonic and the second harmonic are simultaneously superimposed on all tooth surfaces, and the initial phase of the superimposed harmonic is 0°. According to the formula of the mathematical model of the involute gear waviness template, the first and second harmonics designed above are superimposed on the corresponding tooth surface, and the coordinate values ​​of each tooth surface are calculated, and the involute is completed using the machine tool Gear waviness model processing. The schematic diagram of the mathematical model of the involute gear waviness template is as follows Figure 8 shown.

Abstract

The invention discloses an'involute gear waviness sample plate'. Based on the generation principle of an involute profile, a novel involute gear waviness sample plate is designed. Based on the gear mesh principle, according to the generation principle of the involute, the designed waviness is overlapped to an involute profile along the generation line direction of the involute; a plurality of harmonic waves can be overlapped on each gear surface according to the design aim; the wave lengths of the harmonic waves and the initial phase position are required to be calculated according to the gear waviness theory; the involute gear waviness sample plate overlaps the specific harmonic waves in a standard gear transmission error curve, finally the estimation of the filtering algorithm of a gear measuring instrument is realized, a complete measurement means for the gear noise theory is provided, and the gear standard sample plate system is perfected.

Description

technical field [0001] The invention relates to gear error measurement technology and a device, and belongs to the technical fields of precision testing technology, instruments and mechanical transmission. Background technique [0002] Gears are the key transmission parts of various mechanical equipment, widely used in automobiles, instrumentation, machine tools, ships, construction machinery, power generation equipment and other fields. With the development of science and technology, gears are developing in the direction of high power density, high reliability, low noise and long life. Ensuring machining accuracy and controlling gear quality are the basis for ensuring gear performance. [0003] Gear errors can be divided into two categories: individual geometric errors and comprehensive errors. Single geometric error includes tooth profile deviation, tooth direction (helix) deviation and tooth pitch deviation; comprehensive error includes tangential comprehensive deviatio...
