Description

Technical Field

[0001] This utility model relates to the field of water pump technology, and in particular to a main shaft for a water pump drive assembly. Background Technology

[0002] The pump drive unit is a key component of a pump unit. It is responsible for transmitting power from the electric motor or other power source to the pump to drive the impeller, thereby achieving the intake, pressurization, and discharge of liquid. In the pump drive structure, the main shaft typically adopts a symmetrical design, with the center line of the main shaft's major diameter as the line of symmetry. One end of the main shaft connects to the working device, and the other end connects to the drive device. The main shaft structure exhibits a gradual decrease in diameter on both sides, with the diameter decreasing horizontally and uniformly in the bearing placement area. Traditional pump drive units often have a one-piece main shaft. However, this one-piece design has certain drawbacks; when the main shaft is damaged, the entire unit often needs to be replaced, resulting in high operating costs. Therefore, a new type of main shaft for pump drive units is needed to solve these problems. Utility Model Content

[0003] The main objective of this invention is to provide a spindle for a water pump drive assembly, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

The connecting assembly consists of a circular plate and square rods. There are two square rods, which are respectively fixedly installed at both ends of the circular plate. Two fixing assemblies are symmetrically installed on the main shaft body and the connecting assembly. The fixing assemblies consist of a main arc-shaped plate, an auxiliary arc-shaped plate, an arc-shaped clamping plate, a guide rod, and fixing bolts. There are two auxiliary arc-shaped plates, which are symmetrically fixedly installed at both ends of the main arc-shaped plate. There are two arc-shaped clamping plates, which are respectively fixedly installed on the inner walls of the two auxiliary arc-shaped plates. There are two guide rods, which are symmetrically fixedly installed on the inner wall of the main arc-shaped plate. The fixing bolts are rotatably installed on the main arc-shaped plate.

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a main shaft for a water pump drive assembly includes a main shaft body 1, which is composed of a first shaft 4 and a second shaft 5. A connecting assembly 2 is mounted on the first shaft 4 and the second shaft 5. The connecting assembly 2 is composed of a circular plate 9 and square rods 10. There are two square rods 10, which are respectively fixedly installed at both ends of the circular plate 9. Two fixing assemblies 3 are symmetrically installed on the main shaft body 1 and the connecting assembly 2. The fixing assembly 3 is composed of a main arc plate 14, an auxiliary arc plate 15, an arc-shaped clamping plate 16, a guide rod 17, and fixing bolts 19. There are two auxiliary arc plates 15, which are symmetrically fixedly installed at both ends of the main arc plate 14. There are two arc-shaped clamping plates 16, which are respectively fixedly installed on the inner walls of the two auxiliary arc plates 15. There are two guide rods 17, which are symmetrically fixedly installed on the inner walls of the main arc plate 14. The fixing bolts 19 are rotatably installed on the main arc plate 14. When the first shaft 4 or the second shaft 5 is damaged, it can... The first shaft 4 and the second shaft 5 can be separated to replace either the first shaft 4 or the second shaft 5 individually. The method for separating the first shaft 4 and the second shaft 5 is to use a tool to rotate the fixing bolt 19 on the fixing assembly 3, so that the fixing bolt 19, along with the main arc plate 14, the auxiliary arc plate 15, the arc-shaped clamping plate 16, and the guide rod 17, moves outward. When the arc-shaped clamping plate 16 moves out of the fixing slot 8, the fixing of the first shaft 4 and the second shaft 5 is released. Then, the first shaft 4 and the second shaft 5 can be separated to replace either the first shaft 4 or the second shaft 5. Then, the new first shaft 4 or the second shaft 5 can be fitted onto the square rod 10 on the connecting assembly 2. Finally, the fixing bolt 19 is reversed so that the arc-shaped clamping plate 16 is inserted into the fixing slot 8. At this time, the first shaft 4 and the second shaft 5 will be fixed together, thus completing the replacement of the first shaft 4 or the second shaft 5.

[0020] Finally, by setting up a spindle body 1 composed of a first shaft 4 and a second shaft 5, the spindle body 1 can be disassembled. Thus, when the first shaft 4 or the second shaft 5 on the spindle body 1 is damaged, the first shaft 4 or the second shaft 5 can be replaced separately, thereby reducing the cost of use. By setting up a connecting component 2 and a fixing component 3, the first shaft 4 and the second shaft 5 can be easily assembled together, which ultimately facilitates the disassembly and replacement of the first shaft 4 and the second shaft 5.

[0021] Furthermore, a square hole 6 is provided at one end of the first shaft 4 and the second shaft 5. Two connecting grooves 7 are symmetrically provided on the outer walls of the first shaft 4 and the second shaft 5 at one end. A fixing groove 8 is provided on the inner wall of the connecting groove 7. The circular plate 9 on the connecting assembly 2 is located between the first shaft 4 and the second shaft 5. The square rod 10 is inserted into the square hole 6. Two storage grooves 11 are symmetrically provided on the outer wall of the circular plate 9. A threaded hole 12 is provided on the inner wall of the storage groove 11. Two guide holes 13 are symmetrically provided on the inner wall of the storage groove 11 and on both sides of the threaded hole 12. When it is necessary to disassemble the first shaft 4 or the second shaft 5, the first shaft 4 or the second shaft 5 can be removed from the square rod 10. When it is necessary to install the first shaft 4 or the second shaft 5, the first shaft 4 or the second shaft 5 can be fitted onto the square rod 10 on the connecting assembly 2 through the square hole 6.

[0022] Furthermore, the main arc-shaped plate 14 on the fixing assembly 3 is installed in the storage groove 11. An installation groove 18 is formed on the main arc-shaped plate 14 and between the two guide rods 17. The installation groove 18 penetrates the main arc-shaped plate 14 both inside and out. A fixing bolt 19 is rotatably installed in the installation groove 18 and simultaneously installed in the threaded hole 12. The guide rod 17 is movably inserted into the guide hole 13. The auxiliary arc-shaped plate 15 on the fixing assembly 3 is installed in the connecting groove 7, and the arc-shaped retaining plate 16 is installed in the fixing groove 8. Because the fixing bolt 19 and the main arc-shaped plate 14 are rotatably connected, and the guide rod 17 is movably inserted into the guide hole 13, when the fixing bolt 19 is rotated using a tool, the main arc-shaped plate 14, the auxiliary arc-shaped plate 15, and the arc-shaped retaining plate 16 move together. The clamping plate 16 and guide rod 17 will not rotate with the fixing bolt 19. As the fixing bolt 19 moves within the threaded hole 12, the main arc plate 14, auxiliary arc plate 15, arc clamping plate 16, and guide rod 17 will be driven by the fixing bolt 19. When the main arc plate 14, auxiliary arc plate 15, arc clamping plate 16, and guide rod 17 move inward, and the arc clamping plate 16 is embedded in the fixing slot 8 opened on the first shaft 4 and second shaft 5 sleeved on the square rod 10, the first shaft 4 and second shaft 5 will be fixed together. Conversely, when the main arc plate 14, auxiliary arc plate 15, arc clamping plate 16, and guide rod 17 move outward, and the arc clamping plate 16 moves out of the fixing slot 8, the fixing of the first shaft 4 and second shaft 5 will be released.
