Compact gear box and mounting method of gears

Abstract

The invention discloses a compact gear box and a mounting method of gears. The compact gear box comprises an integrated aluminum alloy outer shell. The aluminum alloy outer shell is composed of a gearshell located at the upper end and horizontally arranged and an output shell located at the vertical lower end and obliquely arranged. A gear shifting gear set is mounted in the gear shell, and a power output gear set connected with the gear shifting gear set is mounted in the output shell. The power output gear set comprises a power transmission shaft and a sector conduction gear. The gear shifting gear set comprises a bevel gear, a semi-open hole with the diameter slightly larger than that of a supporting portion is formed in the lower end of a power input hole, and the sector conduction gear and the bevel gear are assembled through the semi-open hole in an engaged manner. The integrated compact gear box overcomes all the defects of an existing split assembled gear box, and is low in weight and compact in internal structure, thus, the assembling manner of the gears of the compact gear box are different from the assembling manner of the existing split assembled gear box inevitably, the compact gear box is simple and ingenious in assembly, labor is saved, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of gearboxes, in particular to a compact gearbox and a gear installation method. Background technique [0002] Micro tillage machine is a kind of agricultural machinery widely used in mountainous areas and other agricultural lands. It is small in size, flexible in use and popular. However, the gearboxes used in the power system of micro tillage machines on the market are generally split assembly type. , which is composed of the upper gear box at the upper end and the lower travel box at the lower end through bolt locking. It has a large volume and high oil consumption. The upper gear box is made of aluminum products, and the lower travel box is made of cast iron, which is heavy; Sector gears are used to transmit power between the travel boxes. After a long period of use, the bolts between the upper gear box and the lower travel box are easily worn, resulting in oil leakage. [0003] Therefore, those skilled...
