Description

Technical Field

[0001] This utility model relates to the field of commutators, and specifically to a commutator. Background Technology

[0002] The commutator is a crucial component of the armature in both DC and AC commutator motors. Its function is to change the direction of current as the motor rotates, ensuring continuous motor operation. In generators, the commutator is responsible for converting alternating current (AC) to direct current (DC). Commutators require lubrication, especially gear commutators, as lubrication enhances their efficiency and extends their service life.

[0003] Existing commutators typically require disassembly for lubrication, which is cumbersome and requires ensuring the lubricant level matches the installation location; otherwise, lubrication will be affected. Secondly, commutators on the market usually come with an integrated base, which limits their adaptability and prevents them from quickly adapting to different drive devices or installation environments. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a commutator that is convenient for changing and replenishing lubricating oil and for easy disassembly and replacement of the base, in light of the current state of the technology.

[0005] This utility model is achieved through the following technical solution: This utility model proposes a commutator, including a commutator and a base. Output bearings and input bearings are respectively installed at both ends inside the commutator. An oil inlet is provided at the upper end of the commutator, and an oil supply pipe is provided on the side of the commutator. The oil inlet and the oil supply pipe are arranged perpendicularly, and the bottom of the oil inlet extends through and into the interior of the oil supply pipe. An inner groove is provided at the bottom of the commutator, and a threaded ring is embedded and fixed inside the inner groove. Positioning holes are provided at the four corners of the commutator near the inner groove. Threaded grooves corresponding to the threaded ring are provided on the base, and threaded holes corresponding to the positioning holes are provided at the corners of the base.

[0006] Furthermore, there are two output bearings and one input bearing. One input bearing meshes with each of the two output bearings. Output shafts and input shafts are respectively provided at the ports of the output bearings and input bearings.

[0007] Furthermore, there are three oil delivery pipes, and each of the three oil delivery pipes is equipped with a nozzle at its front end, with the nozzles corresponding to the output bearing and the input bearing, respectively.

[0008] Furthermore, both the oil inlet and the oil delivery pipe are equipped with sealing caps, which are made of rubber.

[0009] Furthermore, a piston rod passes through the tail end of the oil pipeline, and a handle is fixedly connected to the tail end of the piston rod.

[0010] Furthermore, the threaded hole is internally threaded with a locating pin, which penetrates the threaded hole and extends to the inner top wall of the locating hole.

[0011] Furthermore, a maintenance cover is provided at the top of the commutator.

[0012] Furthermore, the threaded ring is fixed to the inner ring of the inner groove by screws.

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] This invention features an oil inlet at the top of the commutator, with its bottom extending directly into the side oil supply pipe. This allows lubricating oil to flow more directly and effectively to the components requiring lubrication, improving lubrication efficiency and equipment reliability. The vertical alignment of the oil inlet and the oil supply pipe simplifies the lubricating oil replacement process, enabling maintenance personnel to quickly change and replenish the lubricating oil, reducing maintenance time and labor intensity. Furthermore, the threaded ring installed at the bottom of the commutator mates with the threaded groove on the base, enhancing the connection strength between the commutator and the base. The threaded ring's fixing method also simplifies the installation and disassembly of the base. Additionally, the positioning holes at the four corners of the commutator's bottom correspond to the threaded holes at the corners of the base, significantly improving the installation accuracy between the commutator and the base. The use of positioning holes ensures accurate alignment of the commutator during installation, reducing installation errors and improving the overall structural stability and reliability.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, a commutator in this embodiment includes a commutator 1 and a base 2. A maintenance cover 111 is provided at the top of the commutator 1 for easy inspection and maintenance. Output bearings 3 and input bearings 4 are respectively installed at both ends inside the commutator 1 to transmit power and support the commutator 1. An oil inlet 5 is provided at the upper end of the commutator 1, and an oil supply pipe 6 is provided on the side of the commutator 1. The oil inlet 5 and the oil supply pipe 6 are arranged perpendicularly. The bottom of the oil inlet 5 penetrates and extends into the interior of the oil supply pipe 6. Both the oil inlet 5 and the oil supply pipe 6 are equipped with seals. The cover 15 and the sealing cover 15 are made of rubber. The bottom of the commutator 1 has an inner groove 7, and a threaded ring 8 is embedded and fixed inside the inner groove 7. The threaded ring 8 is fixed to the inner ring of the inner groove 7 by screws 81. The four corners of the commutator 1 near the inner groove 7 have positioning holes 9. The base 2 has a threaded groove 10 corresponding to the threaded ring 8. The corners of the base 2 have threaded holes 11 corresponding to the positioning holes 9. The threaded holes 11 are internally threaded with positioning pins 14. The positioning pins 14 pass through the threaded holes 11 and extend to the inner top wall of the positioning holes 9.

[0024] This application provides a commutator that solves the problems of the prior art, which involves disassembling the commutator to replenish lubricating oil. This operation is cumbersome and requires ensuring that the amount of lubricating oil replenished is consistent with the installation position, otherwise it will affect the lubrication effect of the commutator. Secondly, commutators on the market are usually equipped with an integrated base, which limits the adaptability of the commutator and makes it impossible for it to quickly adapt to different drive equipment or different installation environments. The overall idea of ​​this embodiment to solve the above problems is that the upper end of the commutator 1 is provided with an oil inlet 5, which is the inlet for injecting lubricating oil. Lubricating oil can be easily added to the commutator 1 through the oil inlet 5. An oil supply pipe 6 is located on the side of the commutator 1, which transmits lubricating oil from the oil inlet 5 to the output bearing 3 and input bearing 4 that require lubrication. The vertical arrangement between the oil inlet 5 and the oil supply pipe 6 facilitates direct flow of lubricating oil, reduces flow resistance, and ensures that the lubricating oil can smoothly reach the lubrication points. Furthermore, a threaded ring 8 is embedded in the inner groove 7 at the bottom of the commutator 1. The threaded ring 8 is fixed to the inner ring of the inner groove 7 by screws 81, providing a stable threaded connection between the commutator 1 and the base 2. The commutator 1 has positioning holes 9 at the four corners near the inner groove 7. The positioning holes 9 are used to align with the threaded holes 11 on the base 2 to ensure the precise positioning of the commutator 1 during installation. The base 2 has threaded grooves 10 corresponding to the threaded ring 8. When the commutator 1 is placed on the base 2, the threaded ring 8 and the threaded groove 10 cooperate to achieve a fixed connection between the commutator 1 and the base 2. Finally, the positioning pin 14 passes through the threaded hole 11 and extends to the inner top wall of the positioning hole 9. The positioning pin 14 ensures the correct position of the commutator 1 on the base 2 and prevents misalignment or displacement during use.

[0025] like Figure 1 and Figure 2 As shown, there are two output bearings 3 and one input bearing 4. One input bearing 4 meshes with two output bearings 3 respectively. Output shaft 31 and input shaft 41 are respectively provided at the ports of output bearing 3 and input bearing 4.

[0026] As one implementation, the dual output bearing 3 configuration provides additional power output, which can be used to drive multiple loads or achieve more complex mechanical control. The configuration of one input bearing 4 meshing with two output bearings 3 improves the power distribution flexibility of the commutator 1.

[0027] like Figure 1 and Figure 3 As shown, there are three oil supply pipes 6, and each of the three oil supply pipes 6 has a nozzle 61 at its front end. The nozzle 61 corresponds to the output bearing 3 and the input bearing 4, respectively.

[0028] In one implementation, the oil supply pipes 6 are located on the side of the commutator 1, and there are three of them. This allows the commutator 1 to have multiple oil supply paths to ensure that the lubricating oil can be more effectively distributed to each bearing. Each oil supply pipe 6 has a nozzle 61 at its front end, and the nozzles 61 correspond to the output bearing 3 and the input bearing 4 respectively, so that the lubricating oil can be directly delivered to the position of each bearing. The nozzles 61 are conical in shape to adapt to the spray angle and flow rate of the lubricating oil.

[0029] like Figure 4 As shown, a piston rod 12 passes through the tail end of the oil pipe 6, and a handle 13 is fixedly connected to the tail end of the piston rod 12.

[0030] As one implementation method, the conventional commutator adopts a fixed oil supply pipe design, which cannot adjust the flow rate of lubricating oil as needed. This leads to insufficient or excessive lubricating oil supply in some cases. This application adds a piston rod 12 and a handle 13 to the oil supply pipe 6 to facilitate the control of the flow rate and pressure of lubricating oil and meet the lubrication needs under different working conditions.

[0031] The specific implementation process of this embodiment is as follows: The commutator 1 is provided with an oil inlet 5 at the top for easy addition of lubricating oil; three oil supply pipes 6 are provided on the side, each with a conical nozzle 61 at the front end, which is directly aligned with the output bearing 3 and the input bearing 4 to ensure effective distribution of lubricating oil; the tail end of the oil supply pipe 6 is equipped with a piston rod 12 and a handle 13 to control the flow rate and pressure of lubricating oil; the inner groove 7 at the bottom of the commutator 1 is embedded with a threaded ring 8 and fixed by a screw 81, which cooperates with the threaded groove 10 on the base 2 to achieve a stable connection between the commutator 1 and the base 2; the positioning holes 9 at the four corners of the commutator 1 cooperate with the positioning pins 14 in the threaded holes 11 of the base 2 to ensure the correct installation position of the commutator 1. This application simplifies the lubrication process of the commutator and improves its adaptability and power distribution flexibility.
