Abstract

The invention relates to a farm mechanical shaft forge piece which comprises a transmission shaft and a flange, wherein the flange is located at the left end, and the flange and the transmission shaft are integrally forged. The outer diameter of the transmission shaft is increased from the right end to the left end, and the total length d of the transmission shaft and the flange is 460-470 mm; the thickness d1 of the flange is 35-40 mm, and the outer diameter D of the right end of the transmission shaft is 75-80 mm; the outer diameter D1 of the flange is 250-255 mm, and the right end face of the transmission shaft is provided with a boss with the diameter smaller than that of the transmission shaft and the thickness being 9-11 mm; and the peripheral wall of the left end of the transmission shaft is connected with the middle of the flange through a curve face with the size being gradually increased. The farm mechanical shaft forge piece is reasonable in structural design, by adoption of one-time forge-forming and structure optimization of the joint, the mechanical performance of the overall mechanical shaft is improved, and the service lift is prolonged.

Description

technical field [0001] The invention relates to an agricultural machinery shaft forging. Background technique [0002] At present, the shaft of agricultural machinery, such as the rear wheel shaft of a tractor, the rear wheel shaft and the flange used as the hub or connected to the hub are mostly connected by bolts. The mechanical shaft of this structure cannot meet the load requirements of the agricultural machine in terms of strength. The phenomenon of broken shaft will affect the driving safety of agricultural machinery. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide an agricultural machinery shaft forging with reasonable structural design, one-time integral forging to ensure strength, and optimized structure. [0004] The technical scheme that realizes the object of the present invention is as follows: [0005] Agricultural machinery shaft forgings, including the transmission shaft, and the flange p...
