Abstract

The invention belongs to the technical field of agricultural machinery, and particularly relates to a gear transmission case. In order to solve the technical problems, the invention provides the gear transmission case which is uniform in transmission stress, is convenient in gear-shifting connection layout and is convenient for gear shifting. The gear transmission case comprises a main case, a first bearing, a second bearing, a third bearing, a first rotary shaft, a second rotary shaft, a third rotary shaft, an HST hydraulic continuously variable transmission device, a first HST output shaft and the like; the first bearing, the second bearing and the third bearing are arranged in the main case; the first rotary shaft is mounted on the first bearing; the second rotary shaft is mounted on the second bearing; and the third rotary shaft is mounted on the third bearing. The gear transmission case achieves the effects of uniform transmission stress, convenient gear-shifting connection layout and convenient gear shifting, is of a totally enclosed type, realizes totally-engaged sleeve type gear shifting, is long in service life and is novel in structure.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a gear box. Background technique [0002] In recent years, my country's corn planting area has stabilized at about 400 million mu, accounting for more than 17% of the total planting area of ​​crops in the country, ranking second among the three major grains in China, second only to the United States, and ranking second in the world. It involves arable land and many farmers, and has a great impact. At present, the mechanization level of corn harvesting in my country is relatively low. [0003] The drive axle of the corn harvester in the prior art adopts the route of clutch input and gear transmission, and also adopts the existing transmission to install a transition disc to connect the hydraulic transmission device. The disadvantages of these two structures are: many gears, complex structure, hanging The gears are frequent, and the clutch friction plat...
