Background
The thrust disc is a structure used for bearing axial force on a high-speed gear transmission shaft in high-speed gear transmission.
The traditional thrust disc only comprises a split inner shaft sleeve 21 and an outer thrust disc 20 (figure 1), and the friction force is generated by the assembling tightness between the two to transmit the axial force, so the requirement on the assembling interference tightness is high. The thrust disc needs to be heated to a very high temperature during assembly, which requires a relatively complex heating device and is not properly protected, which may cause serious injury to the operator. When disassembling, a hydraulic drawing device is needed. And thus is very difficult to assemble or disassemble. The thrust disc needs to be axially dimensioned on the assembly by grinding.
Disclosure of Invention
The purpose of the invention is as follows: according to the invention, by designing the novel thrust disc structure capable of generating tightness by adjusting hydraulic pressure, the thrust disc is convenient to mount and dismount, the thrust disc cannot be scrapped due to dismounting damage, personal injury in the assembling process can be reduced due to the fact that heating installation is not needed, and the axial position of the thrust disc can be ensured through assembly adjustment.
The technical scheme of the invention is as follows: the utility model provides a thrust disc structure, by the interior axle sleeve of subdivision formula 1 and outer thrust disc 2 constitution, the axle sleeve is adorned earlier on transmission shaft 4 in the subdivision formula, outer thrust disc 2 cover is on the axle sleeve 1 in the subdivision formula, characterized by, with outer thrust disc 2 hole expansion, the corresponding external diameter of axle sleeve 1 and outer thrust disc 2 reduces in the subdivision formula, increase a hydraulic pressure cover 3 that rises between axle sleeve 1 and outer thrust disc 2 in the subdivision formula, 3 elastic ring upper surfaces of hydraulic pressure cover 3 contact with thrust disc 2, the elastic hydraulic pressure ring lower surface of hydraulic pressure cover 3 and the contact of axle sleeve 1 in the subdivision formula.
The split inner shaft sleeve 1, the outer thrust disc 2, the hydraulic expansion sleeve 3 and the transmission shaft 4 are enclosed to form a hydraulic cavity.
The hydraulic expansion sleeve 3 further comprises a pressure adjusting screw, a screw hole is formed in the inner end face of the elastic hydraulic ring and communicated with the hydraulic cavity, and the pressure adjusting screw is arranged in the screw hole.
The elastic hydraulic ring is provided with a flange edge.
The elastic hydraulic ring with the flange edge is closed.
The thrust disc structure is axially positioned with the thrust disc 2 through the hydraulic expansion sleeve 3.
The pressure adjusting screw and the screw hole are sealed through threads.
The pressure of the hydraulic expansion sleeve 3 is adjusted, and the split inner shaft sleeve 1, the thrust disc 2 and the hydraulic expansion sleeve 3 are tightly hooped on the shaft
The invention has the beneficial effects that: the invention does not affect the original gear box structure using the thrust disc;
the axial positioning of the thrust disc can be realized by adjustment during assembly, and the matched grinding processing is not needed, so that the manufacturing cost is reduced; the invention is easy to assemble, does not need hot assembly, and can generate tightness and friction force through the pressure adjusting screw. Because no hot charging is adopted, an assembler cannot be damaged by heat; when the pressure adjusting screw is used for dismounting, the pressure adjusting screw can be used for releasing the pressure, the dismounting can be easily carried out, a complex tool is not needed for dismounting, and parts cannot be damaged.
