Problems solved by technology

[0003] Bevel gears were processed on special bevel gear machines in the past, but due to problems such as tool retraction (milling cutter disc and grinding wheel disc), it was impossible to process integrated bevel gears. Usually, the bevel gear and the optical axis are processed separately, and then the bevel gear and the optical axis are processed separately. The optical axis is baked together, but the bevel gear baked together with the optical axis is used. Compared with the one-piece bevel gear, the stability of the overall structure will be affected. At the same time, there must be precision in the baking process. The error affects the overall accuracy of the bevel gear, and the processing is more cumbersome, which greatly reduces its production efficiency

specific Embodiment approach

[0039] Such as figure 1 , figure 2 The specific embodiment of the processing method of integral bevel gear of the present invention is shown, comprising the following steps:

[0040] A. Material preparation: forging blank, forging ratio = 4, provide material report and flaw detection report, heat the blank to 930°C for 3 hours after normalizing, cool it to room temperature in the air, and then heat it to 680°C for 3 hours. Finally, the resulting workpiece is cooled to room temperature in air;

[0041] B. Drill the center hole at both ends of the blank forged in step A, and select the B5 center hole;

[0042] C. Rough turning: Clamp the workpiece obtained in step B on the lathe, turn the outer circle of each step of the workpiece with the turning tool, and remove the oxide skin on the surface of the workpiece, and keep it to the maximum size;

[0043] D. Flaw detection: The workpiece after rough turning in step C is subjected to ultrasonic flaw detection, so that the workpi...

Abstract

The invention discloses an integrated bevel gear machining method. The integrated bevel gear machining method comprises the steps: material preparing, boring of central holes in the two ends of a blank, rough turning till polishing, crack detection, heating, rough turning, blank re-inspection, semi-fine turning, tooth rough milling, chamfering, heating, shot blasting, fine turning, rough grinding, tooth fine milling, coloring and rolling detecting, detecting, fine grinding and final detecting. The invention aims at providing an integrated bevel gear machining method with great structure stability and high machining precision.

Description

technical field [0001] The invention relates to a manufacturing method of a gear, in particular to a processing method of an integral bevel gear. Background technique [0002] Bevel gears, also called bevel gears, have the advantages of strong load bearing capacity, low noise and good lubricity, and are widely used in industrial transmission equipment, vehicle differentials, locomotives, ships, power plants, steel mills, and railway track inspections. [0003] Bevel gears were processed on special bevel gear machines in the past, but due to problems such as tool retraction (milling cutter disc and grinding wheel disc), it was impossible to process integrated bevel gears. Usually, the bevel gear and the optical axis are processed separately, and then the bevel gear and the optical axis are processed separately. The optical axis is baked together, but the bevel gear baked together with the optical axis is used. Compared with the one-piece bevel gear, the stability of the overa...
