Embodiment 1
[0053] Such as figure 1 Shown is a schematic diagram of the internal structure of a gear box of a twin-screw extruder in the prior art, the gear box includes a box body 1 (only a part of the box body 1 is shown in the figure, those skilled in the art can refer to existing The gear box in the technology is designed and realized), the input shafting 2, the secondary reduction shafting 3, the first output shafting 4, the transition shafting 5 and the second output shafting 6.
[0054] The input shaft system 2 includes an input shaft 21 rotatably connected to the casing 1 and a helical gear H22 fixed on the input shaft 21 . figure 1 The left end of the middle input shaft 21 is exposed on the left side of the casing 1 for connecting with an external motor. The secondary reduction shaft system 3 includes a secondary rotating shaft 31 rotatably connected to the casing 1 and a helical gear K32 and a helical gear M33 fixed on the secondary rotating shaft 31 . The first output shaft s...
Embodiment 2
[0080] This embodiment still takes the gearbox of the twin-screw extruder in Embodiment 1 as an example for illustration, and uses the corresponding angle error measured in Embodiment 1, and supplements the relevant parameters of the helical gear B52, that is, the helical gear A43 and The pitch circle diameter dp of the helical gear B52 when the helical gear B52 meshes B =770mm.
[0081] The in-phase assembly and adjustment method of the parallel output structure in the same direction in this embodiment is based on the first embodiment and considers that there is usually a tooth backlash in the gear pair during operation, and this tooth backlash can be regarded as an assembly error, so Step S21 is included after step S2 in the first embodiment: measure the circumferential backlash between the helical gear A43 and the helical gear B52 and denote it as j AB , the circumferential backlash of the gear pair is an arc length, so j AB It is always a positive number, and the circumf...
Embodiment 3
[0096] Such as Figure 13 Shown is a schematic diagram of the internal partial structure of a twin-screw extrusion granulator gearbox in the prior art. The twin-screw extrusion granulator is also a twin-screw extruder, and the twin-screw extrusion granulator The gearbox includes a case body (not shown in the figure), an input shaft system 7 , a first output shaft system 8 , a transition shaft system 9 and a second output shaft system 10 .
[0097] The input shaft system 7 includes an input shaft 71 rotatably connected to the casing and a helical gear S72 fixed on the input shaft 71 . Figure 13 The left end of the middle input shaft 71 is exposed on the left side of the casing for connecting an external motor. The first output shaft system 8 includes a long output shaft 81 rotatably connected to the box body and a helical gear T82 and a helical gear A83 fixed on the long output shaft 81. The output end of the long output shaft 81 is provided with an integrally formed external...
