Gear cylinder or ball measurement method and system

Abstract

The invention provides a gear column or sphere measuring method and a system thereof. The method and the system are used for measuring an involute spur gear. The system initiates software achieving the method which comprises an image system and a data processing system. The data processing system comprises a CPU, an input device connected with the CPU by means of signal, a memory, a monitor, an output interface. The image system is connected with the CPU by means of signal. The method includes the following steps: the image system is used for inputting the outline of the gear to the coordinate system of the data processing system; two adjacent tooth top corresponding points, one tooth root point between the two points and another tooth top point are selected; the coordinates of the selected points are acquired; the coordinates of the center, the spanned tooth count and other gear parameters of the gear are computed; the outline of the gear is fitted; a base circle is drawn; the origin of a survey coordinate system coincides with the center of the gear; a spanned pin measurement sphere is supposed for measuring spanned pin distance; gear teeth are selected, and the measurement result is output. The method and the system provided by the invention significantly improve the accuracy of measurement of gears and measurement efficiency, which are used simply and conveniently.

Description

technical field [0001] The present invention relates to a gear parameter measurement system, and also relates to a method for measuring gears using the system, more particularly, to a gear cylinder or ball measurement method and system. Background technique [0002] Gears are an indispensable and important part of mechanical equipment, and the accuracy of gears is the most basic factor that determines the accuracy of machinery and equipment. In order to ensure the manufacturing accuracy of gears, not only precise gear manufacturing equipment and production process, but also accurate gear parameter measurement methods are required. Only by accurately measuring gear dimensions and mastering the deviations in gear production can the gear production process be effectively controlled. Ensure that the manufacturing accuracy of the gear meets the design requirements. [0003] Among the many parameters of the gear, the tooth thickness is the indexing arc length between the tooth pr...
