Description

Technical Field

[0001] This utility model relates to the field of commutator technology, and in particular to a commutator with improved dynamic balance performance. Background Technology

[0002] The commutator is a crucial component of the armature in both DC and AC commutator motors. Its primary function is to change the direction of current during motor rotation, enabling continuous operation. The commutator's role in the motor is undeniable. It not only ensures continuous motor operation but also influences efficiency, stability, and maintenance costs. Good commutator design and material selection can reduce wear, extend motor life, and decrease maintenance requirements. As a key component for continuous motor operation, the commutator's design and performance directly impact the overall motor performance. Through continuous technological innovation and optimization, the application of commutators will become more widespread, and their performance will be further improved.

[0003] As shown in the prior art of publication CN211017689U, although the prior art centrally sets the bonding wire step on the slotted commutator segment of the existing single-head configuration, so that the bonding wire step is located in the middle of the slotted commutator segment, the upper and lower ends of the slotted commutator segment can have basically the same weight. In this way, when the slotted commutator is applied to high-speed operating applications, the inertial centrifugal force on the upper and lower ends of the slotted commutator segment is basically the same, and the dynamic balance problem of the slotted commutator can be well solved. Utility Model Content

[0004] The main objective of this invention is to provide a commutator with improved dynamic balance performance. By using multiple mounting rings and stabilizing rings spaced apart, the mass can be increased or decreased at different locations on the outside of the commutator body, thereby correcting the magnitude and location of the imbalance. This avoids vibration caused by centrifugal force due to uneven mass distribution. Furthermore, the multiple spaced mounting rings provide additional support points for the commutator body, enhancing its structural strength and further improving its stability. This effectively solves the problems in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A commutator for improving dynamic balance performance, including a commutator body and functional components installed on the commutator body for improving dynamic balance performance;

[0007] The functional component includes multiple spaced mounting rings, all of which are sleeved on the outside of the commutator body. Stabilizing rings are sleeved on the outside of the top and bottom ends of each mounting ring.

[0008] Preferably, the commutator body has multiple spaced mounting seats on its exterior, and multiple mounting slots are provided on the side of the mounting seats away from the commutator body. The multiple mounting slots are evenly spaced, and the multiple mounting slots on the mounting seats allow the operator to adjust and install the mounting ring with the help of fastening bolts.

[0009] Preferably, the mounting ring has multiple mounting holes on the side away from the commutator body, and the multiple mounting holes correspond to the positions of multiple mounting seats. By the correspondence between the mounting holes and the mounting slots, the fastening bolts can be inserted into the mounting holes and the mounting slots to connect, thereby facilitating the fixing of the mounting ring onto the mounting seat.

[0010] Preferably, the mounting ring is provided with multiple fastening bolts on the side away from the commutator body. The multiple fastening bolts correspond to multiple mounting holes respectively, and the fastening bolts pass through the mounting holes and extend into the mounting groove. The outer side of the fastening bolts is threaded to the inner wall of the mounting groove. The mounting ring is fixed by the fastening bolts, and the fastening bolts can also be easily removed to take off the mounting ring.

[0011] Preferably, a fixing plate is sleeved on the outer side of the fastening bolt near the mounting seat. The fixing plate is installed on the side of the mounting ring near the mounting seat. The fixing plate enhances the connection stability between the mounting ring and the mounting seat, thereby ensuring the tightness of the connection of the mounting ring.

[0012] Preferably, the commutator body includes a bakelite powder matrix and a plurality of commutator segments installed on the outside of the bakelite powder matrix, with an insulating sheet installed between two adjacent commutator segments;

[0013] The mounting base is installed on the outside of the bakelite powder substrate, and the mounting ring is sleeved on the outside of the bakelite powder substrate and multiple commutator segments.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] By using multiple mounting rings and their stabilizing rings spaced apart, the mass can be added or removed at different locations outside the commutator body, thereby correcting the magnitude and location of the imbalance. This avoids vibration caused by centrifugal force due to uneven mass distribution. Furthermore, the multiple spaced mounting rings can provide additional support points for the commutator body, enhancing its structural strength and further improving its stability.

[0016] The mounting ring and mounting base are connected and fixed by fastening bolts, which facilitates the subsequent rotation and disassembly of the fastening bolts to remove the mounting ring. This allows for easy adjustment of dynamic balance by simply replacing or moving the mounting ring, thus improving maintenance convenience. It also facilitates regular inspection or replacement of worn parts, ensuring the long-term stable operation of the equipment. Attached Figure Description

[0023] 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.

[0024] like Figure 1-5 As shown, a commutator for improving dynamic balance performance includes a commutator body and functional components installed on the commutator body for improving dynamic balance performance.

[0025] like Figure 1 , 2 As shown in Figures 4 and 5, the functional component includes multiple spaced mounting rings 1, and all mounting rings 1 are sleeved on the outside of the commutator body. Stabilizing rings 2 are sleeved on the outside of the top and bottom ends of each mounting ring 1.

[0026] By installing multiple spaced mounting rings 1 on the outside of the commutator body, the mass can be increased or decreased at different positions on the outside of the commutator body, thereby correcting the magnitude and position of the imbalance, avoiding vibration caused by centrifugal force due to uneven mass distribution, and the multiple spaced mounting rings 1 can provide additional support points for the commutator body, enhance the structural strength of the commutator body, and further improve the stability of the commutator body.

[0027] Furthermore, since the mounting ring 1 and the mounting base 3 are connected by fastening bolts 6, the operator can rotate and remove the fastening bolts 6 to remove the mounting ring 1. This allows the operator to simply replace or move the mounting ring 1 when the dynamic balance needs to be adjusted, thereby improving the convenience of maintenance. It also facilitates the regular inspection or replacement of worn parts, ensuring the long-term stable operation of the equipment.

[0028] To facilitate the installation of mounting ring 1 and its stabilizing ring 2, as follows: Figure 1-3 As shown, the commutator body has multiple spaced mounting seats 3 on its exterior, and multiple mounting slots 4 are formed on the side of the mounting seats 3 away from the commutator body. These mounting slots 4 are evenly spaced, allowing workers to secure the mounting ring 1 using fastening bolts 6. The distribution of the multiple mounting slots 4 also allows workers to adjust the mounting ring 1 according to dynamic balancing needs, thus improving maintenance convenience. Furthermore, the mounting ring 1 has multiple mounting holes 5 on the side away from the commutator body, which respectively connect to the multiple mounting seats. The positions of 3 correspond to the mounting holes 5 on the mounting ring 1, thereby fixing the mounting ring 1. Then, multiple fastening bolts 6 are provided on the side of the mounting ring 1 away from the commutator body. The multiple fastening bolts 6 correspond to multiple mounting holes 5 respectively, and the fastening bolts 6 pass through the mounting holes 5 and extend into the mounting groove 4. The outer side of the fastening bolts 6 is threaded to the inner wall of the mounting groove 4. Through the threaded connection between the fastening bolts 6 and the mounting groove 4, the fastening bolts 6 can fix the mounting ring 1, thereby ensuring the stability of the mounting ring 1 and the stabilizing ring 2.

[0029] To enhance the connection stability between mounting ring 1 and mounting base 3, such as Figure 4 and 5 As shown, a fixing plate 7 is sleeved on the outer side of the fastening bolt 6 near the mounting base 3. The fixing plate 7 is installed on the side of the mounting ring 1 near the mounting base 3. The fixing plate 7 enhances the connection stability between the mounting ring 1 and the mounting base 3 and prevents the mounting ring 1 from being suspended between the mounting ring 1 and the mounting base 3, which would affect the stability of the mounting ring 1.

[0030] To ensure the stability of the commutator body during operation, such as Figure 1 and 3 As shown, the commutator body includes a bakelite powder substrate 8 and a plurality of commutator segments 9 installed outside the bakelite powder substrate 8, with an insulating sheet 10 installed between two adjacent commutator segments 9; the mounting base 3 is installed outside the bakelite powder substrate 8, and the mounting ring 1 is sleeved on the bakelite powder substrate 8 and the plurality of commutator segments 9, thereby enhancing the stability of the equipment during operation through the plurality of commutator segments 9.

[0031] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
