Embodiment Construction
[0014] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific diagrams.
[0015] refer to figure 1 , figure 2 , a manufacturing process of a gear, comprising 1. material picking, 2. rough turning, 3. heat treatment, 4. finishing turning, 5. grinding two planes, 6. grinding tooth surfaces, 7. chamfering, 8. Deburring, 9. Surface treatment, 10. Grinding two planes, 11 Storage.
[0016] When at least two tooth profile surfaces of the gear are parallel, 6. In the step of grinding the tooth surface, two circular serrated knives 1 parallel to each other are provided on the rotating shaft of the milling machine, and the tooth shape of the gear 2 is formed by the two serrated knives 1 . The serrated knife 1 is made of tool steel, preferably HSS high speed steel. In order to increase the wear resistance of the serrated knife 1...

Abstract
The invention relates to the technical field of gear transmission, in particular to a manufacturing method for a gear. A manufacturing process for the gear comprises the following steps of: getting materials, roughly turning and processing the materials, carrying out thermal treatment on the materials, finish turning and processing the materials, grinding two planes, grinding a tooth surface, chamfering and rounding by R, removing burrs, carrying out surface treatment, grinding two planes and warehousing, wherein when at least two tooth profile surfaces of the gear are parallel, two circular-ring-shaped saw-tooth knives which are arranged in parallel are arranged on a rotary shaft of a milling machine in a tooth surface grinding step, and tooth shapes of the gear are formed through the two saw-tooth knives. With the adoption of the technical scheme, gear production cost is greatly improved and manufacturing efficiency is high when the manufacturing process is used for gear manufacturing.
Description
technical field [0001] The invention relates to the technical field of gear transmission, in particular to a gear manufacturing method. Background technique [0002] The linear conjugate internal gear pump is one of the latest technical equipment of the hydraulic system equipment. It is widely used in the industrial field because of its significant advantages such as quietness, long life, and no trapped oil. The gear in the gear pump usually includes: 1. Picking, 2. Turning (rough), 3. Heat treatment, 4. Turning (fine), 5. Grinding two planes, 6. Milling, 7. Slotting processing, 8. Chamfering, 9. Heat treatment, 10. Marking, 11. Grinding two planes, 12. Grinding inner hole, 13. Grinding outer hole, 14. Grinding outer circle, 15. Grinding tooth surface (coarse), 16. Grinding tooth surface (fine), 17. Chamfering and repairing R, 18. Repairing burrs, 19. Surface treatment, 20. Grinding two planes, 21. Storage. When performing steps 15 and 16, milling machines and forming kniv...
