Description

Technical Field

[0001] The utility model relates to the field of generators, in particular to a high-efficiency transmission generator shaft. Background Art

[0002] The generator shaft refers to the main transmission element connecting the generator rotor with the external load. It is usually a long and thin shaft-like part, and its function is to transfer the rotational kinetic energy generated by the generator rotor to the external load, such as the rotor of the generator or mechanical equipment, to achieve energy conversion and power transmission.

[0003] In traditional generator shaft designs, the connecting shaft often encounters the problem of uneven force distribution when facing the high torque generated during sudden startup. This uneven force distribution usually occurs at the key connection points or load-bearing areas of the shaft, such as gear joints or bearing contact surfaces. Since these areas are subjected to abnormally increased loads in an instant, the pressure they bear may far exceed the design limit of the material, resulting in excessive concentration of the material in these high-pressure areas. Long-term or frequent exposure to this uneven force distribution may cause the connecting shaft to show signs of material fatigue, including the formation of microcracks, gradual reduction in material strength, and eventual possible structural damage or fracture. These problems not only affect the reliability and efficiency of the generator, but also greatly increase the cost and complexity of maintenance and repair. Therefore, the utility model proposes a high-efficiency transmission generator shaft. Utility Model Content

[0004] The utility model mainly provides a high-efficiency transmission generator shaft which is convenient for improving processing efficiency and preventing deviation.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a high-efficiency transmission generator shaft, comprising a generator body and a driving gear, the driving end of the generator body is fixedly connected with an anti-torsion component, and the interior of the anti-torsion component is fixedly connected with a connecting component;

[0006] The anti-torsion assembly includes a connecting shaft, one end of which is fixedly connected to the generator body, a reinforcing shaft is provided at the end of the connecting shaft away from the generator body, a plurality of reverse anti-pressure blocks are fixedly connected to the outer side of the reinforcing shaft, a driven gear is provided on the outer side of the reverse anti-pressure block, and a slot is provided inside the driven gear.

[0007] Preferably, the connecting component includes a card block 1, and three card blocks 1 are provided. The far sides of the three card blocks 1 are fixedly connected to the inner wall of the connecting shaft, and three card blocks 2 are fixedly connected to the inner wall of the connecting shaft. The reinforcing shaft is provided with three positioning grooves 1 near the connecting shaft, and the reinforcing shaft is provided with three positioning grooves 2 at one end near the positioning groove 1.

[0008] The technical effect of adopting the above further solution is: achieving a more uniform distribution of force between the connecting shaft and the reinforcing shaft. This uniform force distribution helps to reduce stress concentration, extend the service life of the equipment, and reduce material fatigue caused by stress concentration.

[0009] Preferably, the driving gear and the driven gear are meshingly connected.

[0010] The technical effect of adopting the above further solution is to provide continuous and smooth force transmission.

[0011] Preferably, the outer side of the reverse anti-compression block is engaged with the slot.

[0012] The technical effect of adopting the above further solution is that it helps to prevent the components from being displaced or loosened when subjected to force, thereby ensuring the normal operation and long-term durability of the device.

[0013] Preferably, the first clamping block is engaged with the second positioning groove, and the second clamping block is engaged with the first positioning groove.

[0014] The technical effect of adopting the above further solution is that it can provide a stronger bonding force between components and increase the stability of the structure.

[0015] Preferably, the outer side of the reinforcing shaft is slidably connected to the inner wall of the connecting shaft.

[0016] The technical effect of adopting the above further solution is: making assembly and disassembly more convenient and simplifying the maintenance process.

[0017] Compared with the prior art, the advantages and positive effects of the utility model are:

[0018] 1. In the utility model, by setting an anti-torsion component, the driving gear transmits power to the driven gear, and then transmits it to the reinforcing shaft. In this process, the card slot inside the reinforcing shaft engages with the reverse anti-pressure block, so that the force from the driving gear first passes through the reverse anti-pressure block designed with an inner arc. This structure uses its geometric shape advantage to increase the force-bearing capacity. Through the inner arc design of the reverse anti-pressure block, the force is more evenly distributed during the transmission process, which effectively solves the problem of uneven force distribution and reduces the risk of material damage caused by force concentration, which not only improves the operating efficiency and reliability of the generator.

[0019] 2. In the utility model, by setting a connecting component, the rotation of the shaft is strengthened to drive the connecting shaft through the positioning groove and the interaction with the clamping block. This design improves the uniform distribution of force, and the width of the clamping block is increased, which reduces the stress per unit area and correspondingly increases the fatigue strength of the structure, so that the shaft can withstand more frequent cyclic loads without being prone to breakage.

[0029] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0031] See also Figure 1 - Figure 3The utility model provides a technical solution: a high-efficiency transmission generator shaft, including a generator body 1 and a driving gear 4, a driving end of the generator body 1 is fixedly connected with an anti-torsion component 2, the interior of the anti-torsion component 2 is fixedly connected with a connecting component 3, the anti-torsion component 2 includes a connecting shaft 21, one end of the connecting shaft 21 is fixedly connected to the generator body 1, and a reinforcing shaft 22 is arranged at one end of the connecting shaft 21 away from the generator body 1, the outer side of the reinforcing shaft 22 is slidably connected to the inner wall of the connecting shaft 21, and the outer side of the reinforcing shaft 22 is fixedly connected with a plurality of reverse anti-pressure blocks 2 3. A driven gear 25 is arranged on the outside of the reverse anti-pressure block 23, and a slot 24 is provided inside the driven gear 25. The driving gear 4 is meshed with the driven gear 25, and the outer side of the reverse anti-pressure block 23 is engaged with the slot 24. The design of the reverse anti-pressure block 23 can withstand the pressure brought to the reinforcing shaft 22 by the driving gear 4 at the moment of starting, so as to prevent the connecting shaft 21 from deformation or fracture during operation. The strong shaft can provide additional support and reinforcement for the connecting shaft 21, thereby enhancing the bearing capacity of the entire system and preventing displacement or loosening under high load conditions.

[0032] like Figure 4 As shown, the connection assembly 3 includes a clamping block 1 31, and there are three clamping blocks 1 31. The far side of the three clamping blocks 1 31 is fixedly connected to the inner wall of the connecting shaft 21. Three clamping blocks 2 32 are fixedly connected to the inner wall of the connecting shaft 21. The reinforcing shaft 22 is provided with three positioning grooves 1 33 near the connecting shaft 21, and one end of the reinforcing shaft 22 near the positioning groove 1 33 is provided with three positioning grooves 2 34. The clamping block 1 31 is engaged with the positioning groove 2 34, and the clamping block 2 32 is engaged with the positioning groove 1 33. Through the cooperation of the clamping block 1 31, the clamping block 2 32, the positioning groove 1 33 and the positioning groove 2 34, a reliable connection between the connecting shaft 21 and the reinforcing shaft 22 is achieved, and torque and pressure can be effectively transmitted to ensure the stability of the connection. This design can also simplify the installation and disassembly process and improve the maintenance efficiency of the system.

[0033] The use method and working principle of the device are as follows: first, when the force of the active gear 4 is transmitted from the driven gear 25 to the reinforcing shaft 22, the slot 24 inside the reinforcing shaft 22 is engaged with the reverse pressure block 23 so that the stress passes through the reverse pressure block 23 before being transmitted to the reinforcing shaft 22. Since the shape design of the reverse pressure block 23 is an inner arc on one side of the active gear 4, the reverse pressure block 23 can increase the stress it bears, and then the connecting shaft 21 is driven to rotate under the rotation of the reinforcing shaft 22. First, the positioning slot 1 33 and the positioning slot 2 34 on the reinforcing shaft 22 slide with the clamping block 1 31 and the clamping block 2 32. When they move to the limited position, the positioning slot 1 33 and the positioning slot 2 34 are completely engaged with the clamping block 1 31 and the clamping block 2 32. Since the width of the clamping block 1 31 and the clamping block 2 32 is increased, the force acting on each unit area is relatively reduced, thereby reducing the risk of stress concentration. Due to the increase in contact area and the reduction in stress concentration, the fatigue strength of the clamping block 1 31 and the clamping block 2 32 is improved. This allows the connection to withstand more cyclic loads without fatigue fracture.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
