Problems solved by technology

[0002] Gear transmission has the advantages of high precision, high efficiency, compact structure, reliable operation, and long life, so it is widely used in various mechanical structures. If a gear fails during use, it generally needs to be replaced with a new gear. For some For equipment with a relatively long history, when the gear fails, due to the lack of technical data or the original manufacturer has stopped the production of this type of equipment, it is often impossible to obtain a replacement gear workpiece in time, which will lead to some expensive equipment. Due to the failure of a certain gear, it cannot continue to be used, causing great economic losses to the manufacturer.

Embodiment 1

[0025] The calculation method of the involute gear parameter of the present embodiment comprises the following steps:

[0026] A. Determine the number of teeth: Determine the number of teeth of the gear by visual observation.

[0027] B. Determining the modulus m and the diameter R of the dedendum circle: Use the German MarSurfLD130 model profile inspection instrument to measure the gear tooth profile to obtain a tooth profile map, such as figure 1 As shown, two complete tooth profiles are measured, namely the first tooth profile 11 and the second tooth profile 12; as figure 2 As shown, make a line segment AB tangent to the first tooth profile 11 on the tooth profile diagram, mark the involute root point C on the second tooth profile 12, and measure the perpendicularity between the involute root point C and the line segment AB If the distance is L, then the modulus m=L / 3, the obtained m value is compared with the standard value of the gear modulus, and the value close to the...

Embodiment 2

[0035] For the application of the calculation method of involute gear parameters as described in Example 1, the number of teeth, modulus, pressure angle, displacement coefficient, addendum circle diameter, and dedendum circle diameter calculated in Example 1 are substituted into the engineering design software Or the gear module in the measurement software generates a standard gear, imports the data measured by the profiler and fitted according to the addendum circle for comparison, modifies the coefficient of variation to make it the best, and determines the shape of the dedendum to obtain a reverse-developed gear. gear.

Abstract

The invention relates to a method for measuring and calculating the parameters of involute gears and its application. The method is based on the precise measurement of the tooth profile by a profile inspection instrument, combined with engineering design software, to directly and accurately determine the modulus, pressure angle, and This method has high measurement accuracy and is easy to implement. It is a practical gear design method and is also suitable for the reverse design of involute splines.

Description

technical field [0001] The invention relates to the technical field of gear measurement, in particular to a method for measuring and calculating parameters of involute gears and its application. Background technique [0002] Gear transmission has the advantages of high precision, high efficiency, compact structure, reliable operation, and long life, so it is widely used in various mechanical structures. If a gear fails during use, it generally needs to be replaced with a new gear. For some For equipment with a relatively long history, when the gear fails, due to the lack of technical data or the original manufacturer has stopped the production of this type of equipment, it is often impossible to obtain a replacement gear workpiece in time, which will lead to some expensive equipment. Due to the failure of a certain gear, it cannot continue to be used, causing great economic losses to the manufacturer. If the accurate parameters of the failed gear can be obtained, the requir...
