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 MarSurf LD130 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 gear...

Embodiment 2

[0035] As in the application of the calculation method of the involute gear parameters 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 fits the data according to the addendum circle for comparison, modifies the variation coefficient to make it the best, and determines the shape of the dedendum to obtain the reverse-developed gear. gear.

Abstract

The invention relates to an involute gear parameter measuring and calculating method and application thereof. Basic parameters such as the modulus, the pressure angle and the displacement coefficient of a measured gear are directly and accurately determined by combining engineering design software based on precise measurement of a profile tolerance inspection tester on a tooth profile, and the method is high in measurement precision, easy and convenient to implement and high in practicability. The invention is a practical gear design method and is also suitable for 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...
