Abstract

The invention belongs to the field of mechanical manufacture and relates to an assembling device and an assembling method for gearbox double-shaft assemblies of a tractor. The assembling device comprises a body component (9), two sets of guide components (10), a locating component (11), a hoisting hook component (12) and a pre-installing component (13). The locating component (11), the guide components (10) and the hoisting hook component (12) are fixedly connected to the body component (9) to form a fixedly connected 'integral assembly'. According to the assembling device and the assembling method for gearbox double-shaft assemblies of the tractor, when the double-shaft assemblies conduct assembly in a casing of a power shifting gearbox in an arranging mode, mesh gears between the double-shaft assemblies are in the normal mesh state, collision mechanical damage produced on the mesh faces of the gears is avoided, and it is further ensured that the double-shaft assemblies are accurately aligned when the double-shaft assemblies fall down, so that seal rings at the shaft ends are prevented from being cut, scratched and damaged. In addition, the assembling device is novel in structure, the assembling method is easy to implement and has good use value.

Description

technical field

[0001] The invention belongs to the field of mechanical manufacturing, and relates to an assembly device and an assembly method for a tractor gearbox biaxial assembly. Background technique

[0002] The gearbox is an important part of the tractor. At present, most domestic tractors still use mechanical shift gearboxes, also known as manual shift gearboxes, the structure and assembly method of the gearbox housing and transmission mechanism (gears, shafts, bearings, sleeves, keys, etc.). like figure 1 shown.

[0003] Depend on figure 1 As we know, in the inner cavity 1a of the machine shift housing (referring to the mechanical shift gearbox housing) 1, there is a transmission structure—the output shaft assembly and the input shaft assembly; there is an upper opening 1b on the top of the machine shift housing 1; On the front side of the casing 1, there are installation holes for the flange 2c for the output shaft and the installation holes for the front beari...
