Description

Technical Field

[0001] This utility model relates to the field of motor power commutation, specifically to a commutator. Background Technology

[0002] An electric motor is a device that converts electrical energy into mechanical energy. The basic working principle of an electric motor is that the action of an electric current in a magnetic field generates torque, which drives mechanical parts to rotate. Electric motors are widely used in various equipment, such as household appliances, industrial machinery, power tools, and electric vehicles. A commutator is required for the commutation and transmission of power within the motor.

[0003] The existing electric power commutator mainly consists of a housing, a drive gear shaft mounted on the housing, a driven gear shaft mounted on the other side wall of the housing, and a speed-changing gear set mounted inside the housing. When using this type of electric power commutator, the housing is first installed at the power output end of the external motor, and the drive gear shaft is connected to the power output end of the external motor, thereby putting the electric power commutator into use.

[0004] While existing motor power commutators can achieve the reversing transmission of motor power, they have several drawbacks. First, during installation, to ensure that the height of the drive gear shaft matches that of the external motor's power output shaft, shims need to be placed at the bottom of the housing to slightly raise the housing height. This process of adjusting the housing height by placing shims is cumbersome, resulting in low installation efficiency. Second, existing commutators require the housing cover to be opened to lubricate the internal gear set during use, making the entire lubrication process cumbersome and inefficient. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a commutator that can automatically lift the housing during installation and automatically lubricate the gearbox during use, in light of the current state of the technology.

[0006] This utility model is achieved through the following technical solution: This utility model proposes a commutator, including a mounting base, a lifting mechanism installed inside the mounting base, a housing installed on the upper side of the lifting mechanism, a commutator mechanism installed inside the housing, a housing cover installed at the top of the housing, and a lubrication mechanism installed on the housing cover. The lifting mechanism includes a bidirectional lead screw, a connecting rod, a threaded sleeve, and a drive motor. The bidirectional lead screw is located at the center of the top of the mounting base. There are two sets of threaded sleeves, symmetrically installed on both sides of the bidirectional lead screw. The connecting rod is installed between the top of each threaded sleeve and the bottom of the housing. The drive motor is installed on the outer wall of the mounting base directly opposite the bidirectional lead screw. The commutator mechanism includes a driving gear shaft, a transmission gear, and a driven gear shaft. The lubrication mechanism includes an oil pump, an oil reservoir, and an oil spray nozzle. The oil reservoir is installed on one side of the top of the housing cover, the oil pump is installed on the top of the housing cover on the side of the oil reservoir, and the oil spray nozzle is installed at the bottom of the housing cover.

[0007] Furthermore, a limiting platform is reserved at the bottom periphery of the housing, and a retaining edge is reserved at the top of the mounting base above the limiting platform.

[0008] Furthermore, both the limiting platform and the stop are square frame structures, and the limiting platform is slidably engaged with the mounting base.

[0009] Furthermore, the driving gear shaft is rotatably connected to the housing, and the driven gear shaft is rotatably connected to the housing.

[0010] Furthermore, the transmission gear is rotatably connected to the bottom end of the housing, and the transmission gear meshes with both the drive gear shaft and the driven gear shaft.

[0011] Furthermore, the bottom of the fuel injector cover is equipped with a fuel injector, which is located above the gear.

[0012] Furthermore, the bidirectional lead screw is rotatably connected to the mounting base, and the bidirectional lead screw passes through the threaded sleeve and is threadedly connected to the threaded sleeve.

[0013] Furthermore, the top end of the connecting rod is hinged to the housing, and the bottom end of the connecting rod is hinged to the threaded sleeve.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] This invention features a lifting mechanism consisting of a bidirectional lead screw, connecting rod, threaded sleeves, and a drive motor, installed between the top of the mounting base and the bottom of the housing. When the commutator is connected to an external motor, the drive motor rotates the bidirectional lead screw to bring the two sets of threaded sleeves closer together. During this process, the connecting rod enables micro-lifting adjustment of the housing, eliminating the tedious operation of repeated adjustments using shims and improving the installation efficiency of the commutator. Furthermore, a lubrication mechanism consisting of an oil pump, oil reservoir, and oil spray nozzle is installed on the top cover of the housing. Under the action of the oil pump, lubricating oil from the oil reservoir is sprayed onto the gears in the commutator mechanism through the oil spray nozzle, thus achieving lubrication of the gears inside the housing. This eliminates the tedious operation of opening the cover for lubrication, further improving the lubrication efficiency inside the commutator. Attached Figure Description

Detailed Implementation

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, a commutator in this embodiment includes a mounting base 3, a lifting mechanism 4 installed inside the mounting base 3, a housing 2 installed on the upper side of the lifting mechanism 4, a commutator 5 installed inside the housing 2, a housing cover 1 installed at the top of the housing 2, and a lubrication mechanism 6 installed on the housing cover 1. The lifting mechanism 4 includes a bidirectional lead screw 401, a connecting rod 402, a threaded sleeve 403, and a drive motor 404. The bidirectional lead screw 401 is located at the middle of the top of the mounting base 3. There are two sets of threaded sleeves 403, and the two sets of threaded sleeves 403 are symmetrically installed on both sides of the bidirectional lead screw 401. On the side, the connecting rod 402 is installed between the top of each screw sleeve 403 and the bottom of the housing 2. The drive motor 404 is installed on the outer wall of the mounting base 3, directly opposite the double-acting screw 401. The reversing mechanism 5 includes a drive gear shaft 501, a speed change gear 503 and a driven gear shaft 502. The lubrication mechanism 6 includes an oil pump 601, an oil reservoir 602 and an oil spray cover 603. The oil reservoir 602 is installed on one side of the top of the housing cover 1. The oil pump 601 is installed on the top of the housing cover 1, located on one side of the oil reservoir 602. The oil spray cover 603 is installed at the bottom of the housing cover 1.

[0025] This utility model provides a commutator that can automatically lift the housing 2 during installation and automatically lubricate the transmission gear 503 during use. This solves the problems of existing motor power commutators, which, while capable of transmitting motor power, require cumbersome installation processes. Firstly, to ensure the height of the drive gear shaft matches the power output shaft of the external motor, pads need to be placed at the bottom of the housing to slightly raise the housing height. This cumbersome process leads to low installation efficiency. Secondly, existing commutators require opening the housing cover to lubricate the internal gear set during use, making the entire lubrication process cumbersome. The present invention addresses the problem of low lubrication efficiency by employing the following general approach: First, the drive motor 404 rotates the bidirectional lead screw 401, causing the two sets of threaded sleeves 403 to approach each other. During this approach, the connecting rod 402 slightly adjusts the housing 2, ensuring rapid alignment and connection between the drive gear shaft 501 and the external power output end. During lubrication of the commutator, the oil pump 601 sprays lubricating oil from the oil reservoir 602 onto the gear 503 in the commutation mechanism 5 via the spray nozzle 603, thus achieving lubrication of the gear 503 inside the housing 2 and eliminating the cumbersome operation of opening the housing cover 1 for lubrication.

[0026] like Figure 2 and Figure 5 As shown, a limiting platform 7 is reserved at the bottom periphery of the box 2, and a retaining edge 8 is reserved at the top of the mounting base 3 above the limiting platform 7.

[0027] As one implementation method, the limiting platform 7 cooperates with the limiting edge to prevent the housing 2 from sliding off the mounting base 3.

[0028] like Figure 2 and Figure 5 As shown, both the limiting platform 7 and the retaining edge 8 are square frame structures, and the limiting platform 7 and the mounting base 3 are slidably fitted together.

[0029] As one implementation method, the sliding fit installation method allows the mounting base 3 to guide the vertical movement of the housing 2, ensuring convenient lifting and lowering adjustment of the housing 2.

[0030] like Figures 1-2 As shown, the drive gear shaft 501 is rotatably connected to the housing 2, and the driven gear shaft 502 is rotatably connected to the housing 2.

[0031] As one implementation method, the rotating connection installation method can ensure that the driving gear shaft 501 and the driven gear shaft 502 can be easily rotated and adjusted relative to the housing 2 when reversing.

[0032] like Figure 2 As shown, the speed change gear 503 is rotatably connected to the bottom of the housing 2, and the speed change gear 503 meshes with both the drive gear shaft 501 and the driven gear shaft 502.

[0033] In one implementation, after the drive gear shaft 501 rotates under the action of an external motor, it will cause the driven gear shaft 502 to rotate under the action of the transmission gear 503, so that the power of the external motor can be transmitted to the corresponding equipment under the action of the driven gear shaft 502.

[0034] like Figure 2 and Figure 3 As shown, the bottom of the fuel injector cover 603 has a fuel injector nozzle, which is located above the gear 503.

[0035] As one implementation method, the fuel injector is a micro-orifice nozzle, which requires a certain pressure to discharge the lubricating oil from the fuel injector. This design can prevent the residual oil in the fuel spray cover 603 from falling when there is no lubrication.

[0036] like Figure 2 and Figure 4 As shown, the bidirectional lead screw 401 is rotatably connected to the mounting base 3, and the bidirectional lead screw 401 passes through the threaded sleeve 403 and is threadedly connected to the threaded sleeve 403.

[0037] As one implementation method, the rotational installation method makes it more convenient to adjust the rotation of the bidirectional lead screw 401 relative to the mounting base 3, while the threaded connection method allows the threaded sleeves 403 to move closer to each other when the bidirectional lead screw 401 rotates.

[0038] like Figure 2 As shown, the top end of the connecting rod 402 is hinged to the housing 2, and the bottom end of the connecting rod 402 is hinged to the threaded sleeve 403.

[0039] As one implementation method, the hinged connection method can ensure convenient rotational adjustment of the connecting rod 402 relative to the threaded sleeve 403 and the housing 2, so as to achieve fine adjustment of the lifting of the housing 2 when the connecting rod 402 is lifted.

[0040] The specific implementation process of this embodiment is as follows: When in use, the commutator is first installed on the power output side of the external motor, and the commutator is connected to the external power supply and control components. Then, the drive motor 404 drives the bidirectional lead screw 401 to rotate, thereby bringing the two sets of screw sleeves 403 closer together. During the process of the two sets of screw sleeves 403 approaching each other, the connecting rod 402 is used to achieve a slight adjustment of the housing 2, ensuring that the drive gear shaft 501 is quickly aligned and connected with the external power output end, which facilitates the efficient installation and use of the commutator. When the commutator is used for lubrication, the lubricating oil in the oil reservoir 602 is sprayed onto the gear 503 in the commutation mechanism 5 through the oil spray nozzle 603 under the action of the oil pump 601, thereby achieving lubrication of the gear 503 inside the housing 2, eliminating the cumbersome operation of opening the housing cover 1 for lubrication, and improving the lubrication efficiency inside the commutator.

[0041] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
