Abstract: |
To solve the problems of assembly technology, such as high accuracy of worm gear and worm reducer shafting, difficulty in measuring center distance and difficult to guarantee the accuracy of space position between worm gear and worm, etc the technical scheme of precise assembly testing of worm gear and worm shafting with high precision matching and multi-shafting reducer with high space precision is formulated. The method of reference transfer, precision instrument testing and correction calculation of assembly dimension chain is adopted. The assembly precision of shafting has been realized: diameter hop≤0.01mm, end hop≤0.015mm, shafting motion≤0.02mm. The accuracy of the space axis position of worm gear reducer is better than 0.05mm, and the position of the meshing clearance of worm tooth surface is more than 0.02mm. A set of high precision worm gear reducer assembly process method is formed, which can provide effective guidance and reference for the subsequent precision assembly of similar products. |
