Problems solved by technology
The large gear for transmission is the most important mechanical part in the transmission device. It is necessary to ensure that the gear has good reliability, stable transmission and long service life. However, the existing gears have relatively single functions, and the wear is serious after long-term work, and the service life is short , it is necessary to design a gear that is easy to add lubricating oil to avoid wear and prolong the service life of the gear

Embodiment Construction
[0021] The present invention is described below in conjunction with accompanying drawing.
[0022] A kind of processing technology of large gear for transmission of the present invention comprises the following steps:
[0023] (1) forging blank;
[0024] (2) Rough machining: A. Based on the end face of the B end and the outer circumference of the gear body, rough turn the A end face, drill and bore the intermediate shaft hole and the spline hole, and leave a margin of 1.1~1.4mm; B. Take the gear body The end surface of A end and the intermediate shaft hole are used as the reference, and the outer circular contour and B end surface are roughly turned, leaving a margin of 1.1~1.4mm;
[0025] (3) Boring conical counterbore: Based on the end face of end B of the gear body and the intermediate shaft hole, two symmetrical conical counterbore holes are bored on end face A;
[0026] (4) Chamfering of the center shaft hole and the conical counterbore: Based on the end surface of the ...

The invention discloses a processing technology of large gears for transmission, which comprises the following steps: (1) forging blank; (2) rough machining; (3) boring conical counterbore; (4) turning intermediate shaft hole and conical counterbore Hole chamfering; (5) gear hobbing; (6) wheel tooth chamfering; (7) heat treatment; (8) finishing one; (9) finishing two; (10) fitter deburring; (11) gear shaving; (12) Inspection and storage. The processing technology of the large transmission gear of the present invention has simplified procedures and reasonable positioning references. Through multiple processes, different reference planes are selected in an orderly manner, the positioning is accurate and reliable, the margin is evenly distributed, and the processing accuracy is also guaranteed.
Description
technical field [0001] The invention relates to a processing technology of a transmission device, in particular to a processing technology of a large gear for transmission, and belongs to the technical field of mechanical equipment manufacturing and processing. Background technique [0002] A gear is a mechanical element with teeth on the rim that can continuously mesh to transmit motion and power, and plays a transmission role in mechanical equipment. The large gear for transmission is the most important mechanical part in the transmission device. It is necessary to ensure that the gear has good reliability, stable transmission and long service life. However, the existing gears have relatively single functions, and the wear is serious after long-term work, and the service life is short Therefore, it is necessary to design a gear that is easy to add lubricating oil to avoid wear and prolong the service life of the gear. For gears, in addition to processing gear teeth, there...
