Description

Technical Field

[0001] The utility model relates to the technical field of anti-loosening gears of a gear pump, and more specifically, to an anti-loosening gear structure of a gear pump. Background Art

[0002] In the existing gear pump technology, the working principle of the gear pump is to suck in and discharge fluid through the rotation of two impellers. These two impellers not only need to assume the function of drainage, but also keep synchronous operation to ensure the normal operation of the pump. However, long-term use and constant mechanical stress may cause the impeller to loosen, which may affect the efficiency and safety of the gear pump. The loose impeller may cause unstable flow and pressure of the pump, and may even cause pump failure, thus affecting the normal operation of the entire system. In addition, the loose impeller may also cause increased noise and vibration of the pump, further affecting the life of the equipment and the comfort of the operator. Utility Model Content

An inlet pipe 10 and an outlet pipe 11 are respectively disposed on both sides of the pump body 1, and the inlet pipe 10 and the outlet pipe 11 are located in the middle of the driving shaft 2 and the driven shaft 3. The inlet pipe 10 and the outlet pipe 11 are connected to external equipment, and the inlet pipe 10 and the outlet pipe 11 are fitted on the inner wall of the pump body 1 and have fillets 12. The sealing mechanism comprises a socket sleeve 13 and a bearing 14. A plurality of socket sleeves 13 are provided, and bearings 14 are respectively sleeved and mounted on the driving shaft 2 and the driven shaft 3, and the bearings 14 are mounted in the socket sleeve 13. A sealing sleeve 15 and a rotating sleeve 16 are respectively threaded on the two socket sleeves 13 on one side of the pump body 1, and the driving shaft 2 is rotatably connected in the rotating sleeve 16.

[0029] In this embodiment, when the pump body 1 is in use, since the driving wheel 17 on the driving shaft 2 is connected to an external driving device, it can drive the driving shaft 2 to rotate. Since the counterweight wheel 5 and the herringbone gear 6 are respectively installed on the driving shaft 2 and the driven shaft 3, the two herringbone teeth 6 are meshed with each other, and the number of teeth of the herringbone gear 6 is much larger than the number of blades 9.

[0031] In summary, when the overall equipment is in use or running: when the pump body 1 is in use, since the driving wheel 17 on the driving shaft 2 is connected to the external driving device, it can drive the driving shaft 2 to rotate. Since the driving shaft 2 and the driven shaft 3 are respectively installed with a counterweight wheel 5 and a herringbone gear 6, the two herringbone teeth 6 are meshed with each other, and the number of teeth of the herringbone teeth 6 is much larger than the number of blades 9. Therefore, when the two herringbone teeth 6 are synchronously transmitted, the blades 9 on the two impellers 8 no longer bear the role of mutual transmission, so it will effectively reduce the looseness of the impeller 8, and through the action of the two counterweight wheels 5, the shaking and impact caused by various reasons are effectively reduced, thereby improving the continuity of transportation.

[0032] Since the water inlet pipe 10 and the water outlet pipe 11 are respectively connected to the external water supply equipment, the rotation of the two impellers 8 can drive the multiple blades 9 to drive water from the upper and lower sides to the water outlet pipe 11, and then the drainage process can be completed.
