Description

Technical Field

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

[0002] The output shaft is a mechanical component and an important part of mechanical equipment for transmitting power. The main function of the output shaft is to transmit the power generated by the power source, such as the motor or engine, to other mechanical components. However, in traditional output shafts, the output torque is determined by the power device, which is connected to the power unit. In the prior art, a reducer is installed between the output shaft and the power device to increase the torque, but this increases the cost. After searching, application number "202022769954.2" discloses "an output shaft for a planetary reducer", which has a stronger ability to resist greater torque when rotating and is not easily damaged. However, the existing output shafts are generally of one-piece design, and it is difficult to replace and maintain when the internal parts of the output shaft are damaged, resulting in the whole shaft being discarded, which increases the cost. Based on this, we propose an output shaft that is easy to disassemble and maintain. Utility Model Content

[0012] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figures 1-5 The present invention provides the following technical solution: a planetary reduction output shaft, including a power unit 1, a housing 2 mounted on the top of the power unit 1, a toothed groove 3 opened on the inner wall of the housing 2, a connecting plate 4 provided inside the housing 2, a plurality of equidistantly distributed first gears 5 rotatably mounted on the bottom end of the connecting plate 4, the plurality of first gears 5 meshing with the toothed groove 3, a connecting cylinder 6 integrally provided on the top of the housing 2, a bearing 12 installed inside the connecting cylinder 6, the inner ring of the bearing 12 being connected and fixed to the connecting shaft 13 by an interference fit, the connecting shaft 13 being connected to the connecting plate 4, the power unit 1 driving the first gears 5 to rotate, one end of the connecting shaft 13 extending to the outside of the connecting cylinder 6 and having an insertion hole opened at the end, a connector 7 being inserted into the insertion hole, a locking hole 8 being opened on the side of the connecting shaft 13, a locking screw (not shown in the figure) being threaded in the locking hole 8 to fix the connector 7.

[0014] In this embodiment, the power unit 1 includes a drive motor 101 and a mounting base 102. The bottom edge of the mounting base 102 is provided with a flange 103. A through hole 104 is provided in the middle of the mounting base 102. A first screw hole 105 is provided on the surface of the drive motor 101. A second screw hole 106 is provided on the surface of the mounting base 102. The mounting base 102 is connected and fixed to the drive motor 101 through a first connecting screw (not shown in the figure) installed in the first screw hole 105 and the second screw hole 106. The output shaft of the drive motor 101 passes through the through hole 104 and is connected to a second gear 107. The outer shell 2 is sleeved on the outside of the mounting base 102 and the second gear 107 is disposed between a plurality of first gears 5. The second gear 107 is meshed with a plurality of first gears 5. The number of first gears 5 is not less than three.

[0015] Specifically, the mounting base 102 can be disassembled by the first screw hole 105 engaging with the second screw hole 106. The drive motor 101 drives the second gear 107 to rotate, which meshes with the first gear 5, and the first gear 5 meshes with the tooth groove 3. Therefore, when the second gear 107 drives the first gear 5 to rotate, the tooth groove 3 causes the first gear 5 to drive the connecting disc 4 to rotate, which in turn drives the connecting shaft 13 to rotate, thus enabling the output of greater torque. The connecting shaft 13 is secured by a lock. The tight hole 8 allows the connector 7 to be replaced, so the operator can select the appropriate connector 7 as needed. catch It can meet the usage needs of different application scenarios. The connecting shaft 13 is connected to the bearing 12 by interference fit, so the connecting shaft 13 and the bearing 12 can be disassembled. The connecting shaft 13 is set in the housing 2 and fixed by the bearing 12, thus improving the stability of the output power of the connecting shaft 13 and the concentricity of rotation.

[0016] In this embodiment, the side wall of the outer shell 2 is provided with a third screw hole 9, and the side wall of the mounting base 102 is provided with a fourth screw hole 108. The outer shell 2 and the mounting base 102 are fixed by a second connecting screw (not shown in the figure) installed with the internal threads of the third screw hole 9 and the fourth screw hole 108.

[0017] Specifically, the third screw hole 9 and the fourth screw hole 108 allow the housing 2 and the mounting base 102 to be disassembled. After the housing 2 is disassembled, it is convenient for the staff to add lubricating oil into the housing 2. Moreover, after the housing 2 is disassembled, the first gear 5 can be exposed, which facilitates the staff to perform maintenance.

[0018] In this embodiment, a connecting hole 10 is provided on the surface of the connecting disk 4, and a connecting section 11 is provided at one end of the connecting shaft 13. The connecting section 11 is installed in the connecting hole 10 in an interference fit manner.

[0019] Specifically, since the connecting section 11 is connected to the connecting hole 10 by an interference fit, the connecting section 11 can be detached from the connecting hole 10. In this way, the connecting shaft 13 can be removed from the connecting cylinder 6. After the connecting shaft 13 is removed from the connecting plate 4, the connecting plate 4 can be taken out from the outer casing 2. In this way, the output shaft can be easily disassembled and maintained. When internal parts are damaged, they can also be easily replaced, avoiding the need to discard the whole thing and increase costs.

[0020] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
