Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of a balancing shaft shell, and more specifically, to a balancing shaft shell. Background Art
[0002] In the existing technology, the balancing shaft housing is a key component in mechanical equipment for reducing vibration and improving running smoothness. During the installation process, the balancing shaft housing usually needs to be connected to an external fixed structure by bolts. However, since the balancing shaft housing is subjected to constant vibration and impact during operation, long-term use will cause the tightening force of the bolted joint to gradually weaken, resulting in loosening. This relaxation will not only affect the stability of the shaft housing, but may also cause relative displacement between the shaft housing and the fixed structure, thereby affecting the performance and life of the entire mechanical system. In addition, frequent vibrations may also accelerate the wear of the bolts and the shaft housing, further exacerbating the problem of looseness at the connection. Therefore, the existing bolt fixing method has certain limitations during long-term use, and it is necessary to seek a more stable and vibration-resistant installation method. Utility Model Content

The unlocking mechanism and the fixing mechanism are respectively installed on the fixing sleeve 3. The fixing mechanism includes a transverse plate 12 and a tension spring 13. A transverse plate 12 is installed on every two one-way rods 7. One end of the tension spring 13 is connected to the transverse plate 12, and the other end of the tension spring 13 is connected to the side wall of the fixing sleeve 3. A bottom sleeve 14 is coaxially provided on the lower end surface of the fixing sleeve 3. An insertion tube 15 is provided on the rotating sleeve 6, and the insertion tube 15 is rotatably connected in the bottom sleeve 14.
[0029] In this embodiment, when the bolt needs to be fixed, first, the fixing sleeve 3 is clamped in the bottom groove 8, and then the nut 4 is sleeved in the hexagonal groove 9. By clamping the wrench on the lateral groove 22, the rotating sleeve 6 can be driven to rotate. Since the nut 4 is clamped in the hexagonal groove 9, the rotation of the nut 4 can be driven. Then the insertion tube 15 is clamped on the bottom sleeve 14, and the rotating sleeve 6 can be limited. When the nut 4 is fixed, the one-way rod 7 will not be clamped in the one-way groove 11. Therefore, the nut 4 can be effectively fixed, so that the shaft housing body 1 is fixedly connected to the outside world. When the nut 4 is loose, the one-way rod 7 and the one-way groove 11 are in a clamped state, thereby avoiding the loosening of the nut 4 and improving the stability of use.

[0031] More specifically, when it is necessary to release, by pinching the two opposing plates 19, the two release sleeves 17 can be driven to slide toward each other, and then the abutment head 20 is pressed against the reducing groove 21, so that the one-way rod 7 is pulled outward, and then the fixation with the one-way groove 11 is released, and then the connection between the nut 4 and the external rod 5 can be released.
[0032] In summary, when the overall equipment is in use or running: when the bolt needs to be fixed, first clamp the fixing sleeve 3 in the bottom groove 8, and then make the nut 4 sleeved in the hexagonal groove 9, and by clamping the wrench on the lateral groove 22, the rotating sleeve 6 can be driven to rotate. Since the nut 4 is clamped in the hexagonal groove 9, the rotation of the nut 4 can be driven, and then the insertion tube 15 is clamped on the bottom sleeve 14, which can limit the rotating sleeve 6. When the nut 4 is fixed, the one-way rod 7 will not be stuck in the one-way groove 11 at this time, so the nut 4 can be effectively fixed, so that the shaft housing body 1 is fixedly connected to the outside world, and when the nut 4 is loose, the one-way rod 7 and the one-way groove 11 are in a clamped state, thereby avoiding the loosening of the nut 4 and improving the stability of use.
[0033] When it is necessary to release, by pinching the two opposing plates 19, the two release sleeves 17 can be driven to slide toward each other, and then the abutment head 20 is pressed against the reducing groove 21, so that the one-way rod 7 is pulled outward, and then the fixation with the one-way groove 11 is released, and then the connection between the nut 4 and the external rod 5 can be released.
