Description

Technical Field

[0001] This utility model relates to the field of experimental teaching of balancing machines, and specifically provides a multifunctional teaching rotor for balancing machines. Background Technology

[0002] When any rotor rotates around its axis, centrifugal force is generated due to the uneven mass distribution relative to the axis. This unbalanced centrifugal force acts on the rotor bearings, causing vibration, noise, and accelerated bearing wear, thus seriously affecting product performance and lifespan. A balancing machine is an instrument used to measure the rotor's imbalance. By correcting the rotor's imbalance based on the data measured by the balancing machine, the mass distribution of the rotor relative to the axis can be improved, reducing the vibration generated during rotor rotation or the vibration force acting on the bearings to within acceptable limits. Balancing machines are essential equipment for reducing vibration, improving performance, and enhancing quality, playing a crucial role in the manufacturing and assembly of parts in fields such as turbine machinery, automobiles, and electronics. Therefore, conducting experimental teaching on balancing machines in higher education programs related to mechanical engineering, energy, and automation is of great significance.

[0003] Existing balancing machines are divided into vertical and horizontal types, both capable of performing dynamic and static balancing experiments and are characterized by mature technology, ease of operation, and comprehensive functions. However, the rotors currently used in balancing machine teaching are mostly calibration rotors, which have a simple structure, limited function, and poor teaching effectiveness. They cannot fully utilize the functions of the balancing machine and cannot perform various balancing experiments.

[0004] Therefore, providing a multifunctional teaching rotor for balancing machines, so as to facilitate the construction of different rotor forms, simulate various unbalanced forms, and increase the number of experimental teaching platforms, has become an urgent problem to be solved. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a multifunctional teaching rotor for balancing machines, so as to solve the problems of the single structure, simple function and poor teaching effect of the balancing machine calibration rotor currently used in balancing machine teaching.

[0006] The technical solution provided by this utility model is: a multifunctional teaching rotor for a balancing machine, comprising: a rotating shaft, a small disc, a large disc, an expansion sleeve, a counterweight screw, and a balancing bolt. The small disc and the large disc each have a through hole in their center, which is used for the expansion sleeve to connect with the rotating shaft. The end faces of the small disc and the large disc each have evenly distributed counterweight threaded holes for mounting the counterweight screw. The circumferential surfaces of the small disc and the large disc each have evenly distributed balancing threaded holes for mounting the balancing bolt.

[0007] Preferably, the small disc has 12 balance threaded holes and 12 counterweight threaded holes.

[0008] Further preferably, the large disc has 36 balance threaded holes and 8 counterweight threaded holes.

[0009] In a further preferred embodiment, the large disc is evenly distributed with weight-reducing grooves, and the weight-reducing grooves and the counterweight threaded holes on the large disc are arranged sequentially at intervals.

[0010] The multifunctional teaching rotor for balancing machines provided by this utility model can be constructed in different forms by selecting and adjusting the position of the disc. In addition, by changing the counterweight screw, four unbalanced forms can be simulated to meet the needs of the number of teaching sets. Compared with the existing single calibration rotor, it has the advantages of low cost, full functionality, convenient operation, and safety and reliability. It can be widely used in balancing machine experimental teaching in various colleges and universities.

[0011] This multifunctional teaching rotor for balancing machines allows for the addition of counterweights to different discs during balancing machine experiments, simulating all forms of rotor imbalance. It fully utilizes the balancing machine's capabilities, enabling students to understand the characteristics of typical imbalances and balancing operation methods. Furthermore, the relative positions of the discs and support frames can be adjusted during balancing machine experiments, allowing for the construction of various rotor parameters using a single set of parts, increasing the number of experimental setups and facilitating the implementation of teaching activities. Finally, this teaching rotor can also be used for rotor assembly and balancing experiments, helping students master all balancing knowledge from parts manufacturing to assembly, thus improving teaching effectiveness.

[0020] The present invention will be further explained below with reference to specific implementation schemes, but it is not limited to the present invention.

[0021] like Figures 1 to 7 As shown, this utility model provides a multifunctional teaching rotor for a balancing machine, comprising: a rotating shaft 1, a small disc 2, a large disc 3, an expansion sleeve 4, a counterweight screw 5, and a balancing bolt 6. The small disc 2 and the large disc 3 each have a through hole in their center, which is used for connecting the expansion sleeve 4 to the rotating shaft 1. The end faces of the small disc 2 and the large disc 3 each have evenly distributed counterweight threaded holes 7, used to install the counterweight screw 5 to create an imbalance. The circumferential surfaces of the small disc 2 and the large disc 3 each have evenly distributed balancing threaded holes 8, used to install the balancing bolt 6 to correct the imbalance.

[0022] This multi-functional teaching rotor for balancing machines can construct various types of unbalanced rotors by adjusting the disc mounted on the rotating shaft and the counterweight screws mounted on the disc. When placed on the support frame of the balancing machine, the rotor can be driven to rotate by a motor through the coupling or belt of the balancing machine to simulate various forms of imbalance and measure the amount of imbalance. The amount of imbalance can be corrected by installing a balancing bolt of appropriate weight in the designated balancing thread hole of the disc, thus completing the balancing experiment.

[0023] The multifunctional teaching rotor used in the balancing machine can perform the following teaching experiments: static balancing experiment, couple balancing experiment, dynamic balancing experiment, and rotor assembly and balancing experiment. The methods for each experiment are as follows:

[0024] When performing static equilibrium experiments, such as Figure 5 As shown, a large disc is fixedly mounted on a rotating shaft using an expansion sleeve, and the rotating shaft is mounted on a support frame (arrow position in the figure). Different teaching rotors are constructed at any position of the large disc relative to the support frame. A counterweight screw is installed on the counterweight threaded hole on the end face of the large disc to simulate static imbalance. The balancing machine is started to measure the balance, and the appropriate weight of the balancing bolt is installed at the designated position of the balancing threaded hole on the circumference of the large disc based on the result. The balancing machine is started again to check the balance result, and the experiment is completed.

[0025] When performing a couple equilibrium experiment, such as Figure 6As shown, two small discs are fixedly mounted on the rotating shaft at intervals using expansion sleeves, and the rotating shaft is mounted on the support frame (the position indicated by the arrow in the figure). Different teaching rotors are constructed by placing the small discs at any position relative to the support frame. Counterweight screws are installed on the counterweight threaded holes on the end faces of the two small discs to simulate couple imbalance. The balancing machine is started to measure the balance, and the appropriate weight of the balancing bolt is installed on the designated position of the balancing threaded hole on the circumference of the small disc based on the result. The balancing machine is started again to check the balance result, and the experiment is completed.

[0026] When performing dynamic balancing experiments, such as Figure 7 As shown, two small discs and one large disc are fixedly mounted on a rotating shaft using expansion sleeves. The rotating shaft is then mounted on a support frame (as indicated by the arrow in the diagram). The two small discs are mounted on opposite sides of the large disc, and each disc is fixed at an arbitrary position relative to the support frame, thus constructing different teaching rotors. Counterweight screws are installed on the counterweight threaded holes on the end faces of the two small discs and the large disc to simulate dynamic imbalance. A balancing machine is started to measure the imbalance, and based on the results, a balancing bolt of appropriate weight is installed at the designated position on the balancing threaded hole on the circumference of the small disc. The balancing machine is started again to check the balance result, thus completing the experiment.

[0027] When performing rotor assembly and balancing experiments, such as Figure 4 As shown, after balancing the rotor assembly, the 36 balancing bolts were weighed and sorted, with the heaviest and second heaviest bolts paired together, and the lightest and heaviest bolts placed adjacent to each other. After installation, the balancing machine was started to measure and the experiment was completed.

[0028] The number of balance threaded holes 8 and counterweight threaded holes 7 on the small disc 2 can be determined as needed. As an improvement to the technical solution, such as... Figure 2 As shown, the small disc 2 has 12 balance threaded holes 8 and 12 counterweight threaded holes 7.

[0029] The number of balance threaded holes 8 and counterweight threaded holes 7 on the large disc 3 can be determined as needed, as an improvement to the technical solution, such as... Figure 3 As shown, the large disc 3 has 36 balance threaded holes 8 and 8 counterweight threaded holes 7.

[0030] As an improvement to the technical solution, such as Figure 3 As shown, the large disc 3 is evenly distributed with weight-reducing grooves 9, and the weight-reducing grooves 9 and the counterweight threaded holes 7 on the large disc 3 are arranged alternately.

[0031] The specific embodiments of this utility model are written in a progressive manner, emphasizing the differences between each implementation scheme, and the similar parts can be referred to each other.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
