Description

Technical Field

[0001] The present invention relates to the field of motor equipment, and in particular to a motor. Background Art

[0002] A motor generally consists of a stator, rotor, housing, and other auxiliary mechanisms. The stator and rotor are both located within the housing, tightly connected to the stator and housing. The rotating shaft is fixed to the center of the rotor. When the stator is energized, a rotating magnetic field is generated, which drives the rotor and transmits force to the load through the rotating shaft. Therefore, motors are widely used in various industries. However, for some equipment requiring high torque, if the high torque is achieved directly through the motor output shaft, the motor's output power will be very large, and it is easy to cause overload and damage to the motor output shaft. For such applications, a connecting mechanism is required on the motor output shaft to connect to the gearbox through the connecting mechanism. However, after long-term use, the connecting mechanism and the motor output shaft are prone to detachment. Summary of the Invention

[0031] The present invention provides an electric motor 10 .

[0032] A motor 10 includes an output shaft 11, wherein a first fixing hole A is provided in the radial direction of the output shaft 11; a transmission member 12, wherein the transmission member 12 is sleeved on the output shaft 11 and a second fixing hole B is provided on the transmission member 12 and passes through the transmission member 12, wherein the second fixing hole B corresponds to the position of the first fixing hole A; and a first fixing member 13, wherein the first fixing member 13 is inserted into the second fixing hole B and the first fixing hole A.

[0033] For a traditional motor 10, its output shaft 11 is directly connected to an actuator, such as a gear, pulley, or chain, and the actuator is driven to rotate by the output power of the motor 10. For an input end that cannot be directly fixedly connected to the output shaft 11 of the motor 10, the output shaft 11 of the motor 10 is connected to the input end of the actuator through a connecting member. Therefore, when the torque driving the actuator is large, the output shaft 11 of the motor 10 is easily broken, causing the output shaft 11 of the motor 10 to break directly, or during long-term rotation, the output shaft 11 of the motor 10 and the transmission member 12 will fall off due to inertia.

[0034] In view of this, in this embodiment, when the execution device needs to output a driving force with a large torque, the torque generated by the motor 10 as a driving member cannot be directly connected to the execution device. If the execution device is directly driven by the output shaft 11 of the motor 10, the output shaft 11 of the motor 10 may be overloaded at the moment of starting. Therefore, it is necessary to set a gear box 20 or a speed regulating device on the output shaft 11 of the motor 10, such as Figures 1 to 2 As shown, a transmission member 12 is provided between the gear box 20 and the output shaft 11 of the motor 10, and a first fixing hole A is provided on the output shaft 11 of the motor 10. It can be understood that the first fixing hole A can be a blind hole (such as a countersunk hole) or can pass through the output shaft 11 of the motor 10. At the same time, a second fixing hole B is provided on the transmission member 12. The transmission member 12 is sleeved on the output shaft 11 of the motor 10, and the first fixing hole A corresponds to the second fixing hole B. The first fixing member 13 is inserted into the second fixing hole B and the first fixing hole A to fix the transmission member 12 to the output shaft 11 of the motor 10. The transmission member 12 can be provided at the input end of the gear box 20, or can be fixedly connected to the input shaft of the gear box 20. In the above manner, the transmission member 12 can be prevented from falling off from the output shaft 11 of the motor 10 during long-term use.

[0035] As another embodiment, an external thread can be tapped on the output shaft 11 of the motor 10, and an internal thread can be tapped at one end of the transmission member 12. The transmission member 12 is fixedly connected to the external thread of the output shaft 11 of the motor 10 through the internal thread, and a first fixing hole A is opened on the output shaft 11 of the motor 10. The first fixing member 13 is inserted into the second fixing hole B and the first fixing hole A to fix the transmission member 12 to the output shaft 11 of the motor 10. The transmission member 12 can be arranged at the input end of the gear box 20, or can be fixedly connected to the input shaft of the gear box 20. In the above manner, the transmission member 12 can be prevented from falling off from the output shaft 11 of the motor 10 during long-term use.

[0036] Specifically, the first fixing hole A is a through hole that passes through the output shaft 11. In this embodiment, the first fixing hole A is a through hole that passes through the output shaft 11, and the transmission member 12 is inserted into the first fixing hole A through the second fixing hole B until it abuts against the inner wall of the transmission member 12, which helps to improve the stability between the transmission member 12 and the output shaft 11 of the motor 10.

[0037] Specifically, a third fixing hole (not shown) is provided on the transmission member 12 at a position symmetrical to the first fixing hole A and is connected to the first fixing hole A. The first fixing member 13 is inserted into the second fixing hole B, the first fixing hole A, and the third fixing hole, and the two ends of the first fixing member 13 are respectively located in the second fixing hole B and the third fixing hole. In this embodiment, a third fixing hole is provided on the transmission member 12 at a position symmetrical to the first fixing hole A, and the third fixing hole is connected to the first fixing hole A. When the first fixing member 13 is inserted into the first fixing hole A from the second fixing hole B, the first fixing member 13 passes through the output shaft 11 of the motor 10, and the two ends of the first fixing member 13 are respectively located in the second fixing hole B and the third fixing hole, thereby further improving the stability of the transmission member 12 and the output shaft 11 of the motor 10.

[0038] Specifically, the diameter of the transmission member 12 is greater than or equal to the length of the first fixing member 13, so that the first fixing member 13 can be accommodated in the first fixing hole A and the second fixing hole B. In this embodiment, to prevent the first fixing member 13 from interfering with the gear box 20, the total depth of the first fixing hole A and the second fixing hole B is preferably greater than or equal to the length of the first fixing member 13, ensuring that the first fixing member 13 is located in the second fixing hole B.

[0039] Specifically, the motor 10 further includes a transition sleeve 15 disposed between the transmission member 12 and the output shaft 11. The first fixing member 13 sequentially passes through the transmission member 12, the transition sleeve 15, and the output shaft 11. In this embodiment, due to the different specifications of the motor 10, the diameter of the output shaft 11 of the motor 10 also varies. Therefore, for small-sized motors 10, a transition sleeve 15 can be added to the transmission member 12. The transition sleeve 15 is disposed between the transmission member 12 and the output shaft 11, and the three are fixed together by the first fixing member 13, thereby improving the stability between the small-sized motor 10 and the transmission member 12.

[0040] As another preferred solution, an internal thread can be tapped on the inner circumferential wall of the transition sleeve 15, an external thread can be tapped on the outer circumferential wall of the transition sleeve 15, and at the same time, an internal thread can be tapped on the inner circumferential wall of the transmission member 12, and an external thread can be tapped on the output shaft 11 of the motor 10. The transition sleeve 15 is arranged between the transmission member 12 and the output shaft 11 of the motor 10, which can improve the connection stability of the three.

[0041] Specifically, the length of the transmission member 12 in the axial direction of the output shaft 11 is greater than the length of the output shaft 11. In this embodiment, the length of the transmission member 12 is greater than the length of the output shaft 11. After one end of the transmission member 12 is fixedly connected to the output shaft 11 of the motor 10, it is convenient to fix the other end of the transmission member 12 to the gear box 20.

[0042] Specifically, the transmission member 12 is provided with internal teeth at one end away from the output shaft 11, and the internal teeth are used to mesh with the input shaft of the gear box 20. Figures 3 and 4 As shown, in this embodiment, in order to fix the other end of the transmission member 12 with the gear box 20, internal teeth can be provided at the other end of the transmission member 12, that is, internal teeth are provided at the end of the transmission member 12 away from the output shaft 11, so as to facilitate the engagement of the gear box 20 with the other end of the transmission member 12.

[0043] As another embodiment, a fourth fixing hole (not shown) passing through the transmission member 12 can be provided at the other end of the transmission member 12, and a fifth fixing hole (not shown) can be provided on the input shaft of the gear box 20. The fourth fixing hole corresponds to the fifth fixing hole in position, and the first fixing member 13 is also used to fix the other end of the transmission member 12 to the input shaft of the gear box 20. At this time, the first fixing member 13 is located in the fifth fixing hole and the fourth fixing hole.

[0044] Specifically, the first fixing member 13 is connected to the first fixing hole A by interference fit or threaded connection. In this embodiment, the first fixing member 13 is connected to the first fixing hole A by interference fit or threaded connection, which is conducive to enhancing the stability between the first fixing member 13 and the first fixing hole A.

[0045] As another embodiment, hexagonal threaded holes may be provided on the upper and lower end surfaces of the first fixing member 13 to facilitate the worker to insert or remove the first fixing member 13 from the first fixing hole A.

[0046] Specifically, the motor 10 further includes a fixing sleeve 14, which is provided on the outer peripheral wall of the transmission member 12 and is used to seal the first fixing member 13 in the first fixing hole A and the second fixing hole B. Figure 5 As shown, in this embodiment, in order to prevent the first fixing member 13 from being separated from the first fixing hole A and the second fixing hole B after long-term use, the present invention provides a fixing sleeve 14 on the outer peripheral wall of the transmission member 12 to seal the first fixing member 13 in the first fixing hole A and the second fixing hole B.

[0047] Specifically, the fixing sleeve 14 and the transmission member 12 are snap-fitted together. In this embodiment, a snap-fitting groove (not shown) can be provided on the transmission member 12, and a snap-fitting groove (not shown) can be provided on the fixing sleeve 14. For example, at least one snap-fitting groove can be provided on the end surface of the transmission member 12 along the circumference of the axis of the transmission member 12, and at least one snap-fitting groove can be provided on the fixing sleeve 14 along the circumference of the axis of the fixing sleeve 14. The snap-fitting grooves and the snap-fitting grooves correspond to each other. When the fixing sleeve 14 is provided on the transmission member 12, the snap-fitting grooves and the snap-fitting grooves engage with each other. This structure can improve the stability between the fixing sleeve 14 and the transmission member 12.

[0048] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
