Problems solved by technology

However, the steering mechanism of the harvester gearbox still has the common problem of the jaw clutch structure: the steering mechanism is frequently used, and the clutch jaws are frequently combined and separated, so that the joint surface of the clutch jaws wears extremely fast, and the clutch jaws close to the end face The side wears faster, forming a slope, which easily disengages the clutch teeth of the intermediate gear and the steering gear, resulting in a reduction in the transmitted torque; and the production efficiency of parts with clutch teeth is low, and the manufacturin

Abstract

The invention relates to a gearbox steering mechanism on an agricultural machine, which comprises steering shafts 1 and an intermediate gear 4 which is coaxially arranged on the steering shafts 1 and is provided with internal teeth, wherein a left steering gear 3 and a right steering gear 8 are respectively sleeved on the steering shafts 1 at the two sides of the intermediate gear 4 in a sliding way; big teeth meshed with the internal teeth of the intermediate gear 4 are arranged at one sides of the left steering gear 3 and the right steering gear 8, and small teeth are arranged at the other sides; a left steering shift fork 2 and a right steering shift fork 9 are correspondingly arranged on the left steering gear 3 and the right steering gear 8; a left return spring 11 and a right return spring 10 are sleeved at the two ends of the steering shafts 1; and a connecting gear 5 is coaxially fixed on the steering shafts 1, and the connecting gear 5 is arranged between the left steering gear 3 and the right steering gear 8 and is meshed with the internal teeth of the intermediate gear 4. The gearbox steering mechanism has the advantages of novel structure, large transfer torque, long service life, good clutch performance, high production efficiency and low manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a gearbox steering mechanism. Background technique [0002] At present, the steering mechanism of the gearbox on the agricultural machinery mainly adopts the jaw clutch type and the differential type. The existing steering mechanism adopts the jaw clutch type, the intermediate gear has jaws on both sides, and the steering gear with jaws is installed on the left and right, and the intermediate gear is clutched with the steering gear through the jaws. For example, Chinese patent application 201120171478.2 discloses a harvester gearbox steering mechanism with a jaw clutch structure, although it changes the angle between the clutch teeth of the intermediate gear and the steering gear, and changes the angle of the intermediate gear. The way the clutch teeth cut into the angle makes the clutch teeth not easy to fall off, improves the clutch performance, and can reduce w...
