Embodiment 1

[0034] like figure 1 shown, combined with figure 2 , a double-arm oversized gear measuring instrument (also known as a double-horizontal cantilever coordinate measuring machine), including a base 1 that can be arranged on the upper end face of the gear to be measured, and a three-dimensional The measuring unit 2 includes two three-dimensional measuring units 2, and the two three-dimensional measuring units 2 are respectively used for measuring the inner and outer sides of the gear. figure 1 Among them, X, Y, and Z represent three-dimensional coordinate axes, and the arrows on the X, Y, and Z axes represent that the components of the three-dimensional measuring unit can move along corresponding guide rails.

[0035] like figure 2 As shown, the inner and outer sides of the gear, for the outer gear (ie figure 2 For the tested gear 3), the inner side refers to the inner hole area of ​​the external gear, and the outer side refers to the outer tooth surface area of ​​the exter...

Abstract

The invention relates to the technical field of gear measurement, in particular to a double arm type measurement instrument of a super huge type gear. The double arm type measurement instrument of the super huge type gear comprises a base seat placed on the upper end face of a measured gear and three dimensional measurement units suspended below the base seat, wherein the number of the three dimensional measurement units is two, and the two three dimensional measurement units are respectively used to measure the inner side and the outer side of the measured gear. The double arm type super huge type gear measurement instrument adopts a measurement theory of using a small part to measure a large part, and overcomes the disadvantages that the measurement center of the super huge type gear and a coordinate measuring machine need long guide rails, instrument cost is high, and measurement accuracy is difficult to improve.

Description

technical field [0001] The invention relates to the technical field of gear measurement, in particular to a double-arm type oversized gear measuring instrument. Background technique [0002] Gear is the most important and most widely used transmission type in mechanical transmission. It has the advantages of accurate transmission ratio, compact structure and high transmission efficiency. Gears are divided into micro gears, conventional gears, large gears and extra large gears according to their size. By convention, gears with a diameter greater than 3000mm are called oversized gears. Super-large gears are mainly used in some key critical areas and important industries that affect the overall situation, such as power generation, locomotives, mining machinery, large construction machinery, large ships, drilling platforms and rocket launches, etc., which play an important role in the national economy and national defense. very important and irreplaceable. [0003] The precis...
