Description

Technical Field

[0001] This utility model belongs to the field of motor technology, specifically relating to a dual-output shaft motor. Background Technology

[0002] Dual-shaft motors, as power output devices, are widely used in industrial equipment, automated machinery, and robotics due to their ability to transmit torque at both ends, especially suitable for scenarios requiring bidirectional synchronous drive or where space is limited. However, traditional dual-shaft motors typically use a straight-out terminal design, where the terminal group extends outward perpendicularly to the motor end cover. While this structure meets the requirements in conventional applications, when external devices such as reducers need to be installed at both ends of the motor, the straight-out terminals will interfere with the reducer's installation space. This prevents the reducer from directly fitting against the motor end cover, and may even force non-standard designs for the reducer housing or connecting flange (such as adding clearance grooves or adjusting mounting hole positions), thereby increasing the customization cost and structural complexity of the reducer. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a dual-output shaft motor.

[0004] To achieve the above objectives, this utility model discloses a dual-output shaft motor, including a housing, a first end cover and a second end cover respectively disposed at both ends of the housing, a first motor shaft extending from the first end cover, a second motor shaft extending from the second end cover, a terminal mounting base, and wiring terminals;

[0011] In another embodiment, the terminal outlet is an inner groove at the edge of the terminal mounting base end face.

[0012] In another embodiment, the terminal block is formed by bending a sheet-like metal connector;

[0013] The terminal mounting base has a vertical channel that passes through both ends of the terminal. A metal connector passes through the vertical channel and its two ends are exposed to form a second connecting part located inside the housing and a third connecting part extending outside the housing. The second connecting part is bent flat against one end face of the terminal mounting base and fixed by the connector.

[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] A dual-output shaft motor, see Figures 1-3 It includes a housing 100, a first end cover 200 and a second end cover 300 respectively disposed at both ends of the housing 100, a first motor shaft 400 extending from the first end cover 200, a second motor shaft 500 extending from the second end cover 300, a terminal mounting base 600 and a wiring terminal 700.

[0035] The terminal mounting base 600 is located inside the housing 100 near the end of the first end cover 200, and a terminal connector is provided on the terminal mounting base 600. A first clearance hole 110 is provided on the side wall of the housing 100. A wiring terminal 700 is mounted on the terminal mounting base 600, with one end of the wiring terminal 700 fixed to the terminal mounting base 600 via the terminal connector, and the other end of the wiring terminal 700 extending out of the housing 100 through the first clearance hole 110. Both the first end cover 200 and the second end cover 300 are provided with a first connecting portion 210 for mounting the reducer.

[0036] In this embodiment, the motor has a first connecting portion 210 for mounting a reducer on both the first end cover 200 and the second end cover 300. The two motor shafts of the motor, after mounting the reducer, form a geared motor. The terminal block 700 extends from the side wall of the housing 100 through the first clearance hole 110. The terminal block 700 will not interfere with the reducer mounted outside the first end cover 200. Therefore, the reducer does not need to have a clearance groove 230 or similar structure, reducing the customization cost and structural complexity of the reducer. A terminal mounting base 600 is provided to connect the terminal block 700. During assembly, the terminal block 700 can be first mounted on the terminal mounting base 600 and then assembled with the housing 100, which reduces the difficulty of terminal installation.

[0037] The first connecting part 210 has a threaded hole, and the reducer can be installed on the corresponding end cover by bolts.

[0038] In this embodiment, the housing 100 and the second end cap 300 are integrally formed, specifically, they are integrally formed by injection molding. The integral forming of the second end cap 300 with the housing 100 improves the structural strength of the second end cap 300, allowing it to accommodate heavier reducers and providing good adaptability.

[0039] In this embodiment, the second end cover 300 and the housing 100 are separate structures. In order to improve the structural strength of the second end cover 300, the terminal mounting base 600 is annular. The outer side wall of the terminal mounting base 600 is adapted to the inner side wall of the housing 100 to support the housing 100. The first end cover 200 is disposed on the terminal mounting base 600. The terminal mounting base 600 serves as both a connector for mounting the terminal 700 and a reinforcing member for the first end cover 200, thereby improving the strength of the first end cover 200.

[0040] Specifically, one side of the first clearance hole 110 extends to the end face of the housing 100, forming an opening groove as shown in the figure. There are two terminals 700, and the housing 100 is provided with two corresponding first clearance holes 110. Two locking blocks 610 are provided on the periphery of the terminal mounting base 600, and the two locking blocks 610 are respectively locked in the two first clearance holes 110, so that the housing 100 axially supports the terminal mounting base 600. Each locking block 610 is provided with a terminal outlet 611 facing the corresponding first clearance hole 110. In addition to allowing the terminals 700 to extend from the side of the housing 100, the first clearance holes 110 also make full use of the first clearance holes 110 to axially support and limit the terminal mounting base 600, thus making the structure simpler and more compact.

[0041] The locking block 610 has a limiting part 612 near the end of the first end cover 200. The first end cover 200 has a second clearance hole 220 opposite to the limiting part 612, and the inner wall of the second clearance hole 220 is in a limiting engagement with the limiting part 612. The end of the housing 100 has a pressing part 130. The bottom surface of the pressing part 130 presses against the end face of the first end cover 200 away from the terminal mounting base 600. Specifically, the pressing part 130 is a metal sheet punched out from the side wall of the housing 100. During assembly, after the terminal mounting base 600 is assembled, the first end cover 200 is placed on the terminal mounting base 600, and the limiting part 612 is in a limiting engagement with the second clearance hole 220. Then, the metal sheet is bent and pressed onto the first end cover 200, and finally the first end cover 200 is installed.

[0042] The first end cover 200 has a relief groove 230 at its edge, which is opposite to the pressing part 130. The pressing part 130 is located in the relief groove 230. This can prevent the pressing part 130 from being exposed to the first end cover 200 and thus avoid being easily damaged, while also improving the appearance of the motor.

[0043] In this embodiment, the terminal 700 is formed by bending a sheet-like metal connector. Specifically, the terminal mounting base 600 has a vertical channel 620 extending through both ends. The metal connector passes through the vertical channel 620, with both ends exposed, forming a second connecting portion 710 located inside the housing 100 (for communication with the internal wiring structure of the motor, such as carbon brushes, commutators, etc.) and a third connecting portion 720 extending outside the housing 100 (for communication with external wiring of the motor). The second connecting portion 710 is bent flat against one end face of the terminal mounting base 600, and the third connecting portion 720 is bent flat against the other end face of the terminal mounting base 600, ultimately forming the aforementioned terminal 700. By providing a vertical channel 620 inside the terminal mounting base 600 to install the terminal 700, and with both ends of the terminal 700 flat against the corresponding end faces of the terminal mounting base 600, the terminal 700 has high installation reliability and strong operational stability.

[0044] The terminal outlet 611 is an inner groove at the edge of the end face of the terminal mounting base 600, and is connected to the vertical channel 620.

[0045] The terminal connector is a bolt. The second connecting part 710 of the terminal 700 is provided with a connecting hole 711. The bolt passes through the connecting hole 711 and is threaded onto the terminal mounting base 600, thus fixing the second connecting part 710 of the terminal 700 onto the terminal mounting base 600.

[0046] In this embodiment, the inner wall of the housing 100 is provided with a stepped surface 120 for supporting the first end cap 200.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
