Hamenaco precision measures transmission of harmonic gear CSG-45-160-2A-GR motion. Harmonic drive is usually composed of three basic components, including a rigid wheel with inner teeth, a flexible wheel with outer teeth that can produce radial elastic deformation when working, and a wave generator installed in the flexible wheel internal transmission part wave, oval shape, with flexible rolling bearings in the outer ring. The number of external teeth of flexible wheel is less than the number of internal teeth of rigid wheel. When the wave generator rotates, the outer teeth of the flexible wheel corresponding to the long axis direction just completely engage the inner teeth of the rigid wheel
The transmission error of the transmission device is measured by optical dial and reading microscope. This method is to install the low-precision optical dial on the input shaft; A high precision optical dial is mounted on the output shaft. 'Hameenako precision measurement harmonic gear unit CG-45-160-2A-GR (this is true for reduction gear, and the opposite is true for acceleration gear). In order to facilitate adjustment and ensure installation accuracy, a special dial regulator can be used to adjust the end face and radial position respectively.
The transmission error of the transmission device is measured with a theodolite and a parallel light tube. This method is to install an optical dial on the input shaft and read the positioning with the help of a reading microscope. The precision measurement harmonic gear csG-45-160-2A-GR can also use a dial meter as a positioning device when the input shaft Angle is an integer. The theodolite is mounted on the output shaft, and parallel light tubes are set at a distance to be used as a target for the theodolite telescope.
It is also a precise measurement method to measure the transmission error of the transmission device by means of multifaceted and self-collimating parallel light tubes. The measuring principle of this method is the same as that of the above two methods. The precision measuring harmonic gear device CSG-45-160-2A-GR of Hameenako is to install the multi-sided device with fewer faces on the input shaft; The high-precision polyhedron with many faces is installed on the output shaft. On. To the installation of polyhedron, in order to avoid deformation by force, special fixture must be used to ensure the accuracy of measurement.
During measurement, with the help of optical dial positioning, the input shaft is rotated at a certain Angle, and the harmonic gear device CSG-45-160-2A-GR is accurately measured by Hamenacker. Then the output shaft rotation Angle is measured by grating digital goniometer.
