Embodiment Construction

[0024] Attached below figure 2 , 3 The present invention is described further:

[0025] The measurement principle of this embodiment is to change the traditional one-way transmission measurement method into a two-way synchronous drive measurement method. The device is as figure 2 As shown, there are two drive systems included. One set is the measuring gear 4 driving system, which includes the measuring gear 4 , the flexible coupling 7 , the second angle encoder 8 , the second coupling 14 and the second motor 6 . The measuring gear 4 is connected with the flexible coupling 7 , the flexible coupling 7 is connected with the second angle measuring encoder 8 , and the second angle measuring encoder 8 is connected with the second motor 6 through the second shaft coupling 14 . In this way, the second motor 6 drives the second angle measuring encoder 8 , the flexible coupling 7 and the measuring gear 4 to rotate through the second shaft coupling 14 . The other set is the gear un...

Abstract

The invention relates to a drive error measuring method for a close-toothed gear which is belonging to the field of precision technology and meter, mechanical drive. The method specifically is: firstly connecting the to-be measured gear, the driver, the first goniometric coder, the first shaft joint and the first electric motor respectively; then connecting the measuring gear, the flexible shaft joint, the second goniometric coder, the second shaft joint and the second electric motor respectively; the to-be measured gear and the measuring gear are joggled in the single side which are driven by two electric motors; detecting the measuring gear having the displacement phi <2> corresponding to the second goniometric coder, measuring gear shaft angle displacing the phi 1 and the to-be measured gear shaft angle displacement the phi', obtaining the drive error of the close-toothed gear after the calculation. The invention avoids the shortcomings that the close-toothed gear driving the big quality shaft and circular grating to re-rotate, and enhances the measuring precision and reliability of the measuring system, and solves the universal problems of single gear measurement for the close-toothed gear.

Description

technical field [0001] The invention relates to a small modulus gear transmission error measurement method, which belongs to the technical fields of precision testing technology, instruments and mechanical transmission. Background technique [0002] Small modulus gears usually refer to gears with a modulus from 0.1mm to 1mm. Small modulus gears (especially plastic gears, modulus 0.1-0.5mm) are widely used in the IT industry, electronic machinery, aerospace instruments, and precision instruments. With the rapid development of science and technology, higher requirements are put forward for the manufacturing precision and transmission quality of small modulus gears. Small modulus gears lack reliable and effective measurement techniques and means. Therefore, the precise and fast measurement of small modulus gears is a key technical problem to be solved urgently at home and abroad. [0003] The single-sided meshing measurement method occupies a special position in many gear mea...
