Description

Technical Field

[0001] This utility model relates to a motor output shaft structure. Background Technology

[0002] The existing motor output shaft has only one mounting recess. When installing gears, gearboxes or other accessories, it is necessary to use interference fit, clamping fit or key fit to ensure a firm connection between the motor output shaft and the gears, gearboxes or other accessories. This output shaft structure makes installation troublesome and costly. Utility Model Content

[0003] This utility model proposes a motor output shaft structure, including a motor body, a housing and an output shaft on the motor body, a mounting hole on the housing, the output shaft part being disposed inside the housing and extending out from the mounting hole, the output shaft having a first recess and a second recess, the first recess extending from the free end of the output shaft toward the housing, the starting end of the second recess being located on the first recess, and a gap being provided between the second recess and the free end.

[0004] In one or more embodiments, the depth of the second recess is equal to the depth of the first recess.

[0005] In one or more embodiments, the arcuate angle between the beginning end and the end end of the second recess is less than 180 degrees.

[0006] In one or more embodiments, the first recess is provided with a first tail end, the second recess is provided with a second tail end, and the first tail end and the second tail end are coplanar.

[0007] In one or more embodiments, a gap is provided between the first tail end and the second tail end and the housing.

[0008] During installation, first align the output shaft with the mounting port on the accessory, and align the first recess with the protrusion of the mounting port. Then, rotate the accessory or output shaft so that the protrusion rests on the second recess.

[0009] The advantages of this utility model are: quick assembly and disassembly; during installation, simply insert the device and rotate it 90 degrees clockwise to lock it in place; during disassembly, rotate it 90 degrees counterclockwise to pull it out; it has no key, so there is no need for interference fit or clamping, thus saving on manufacturing costs.

[0012] The following description, in conjunction with the accompanying drawings, further illustrates the proposed solution:

[0013] See appendix Figure 1-2 A motor output shaft structure includes a motor body 1, a housing 2 and an output shaft 3 disposed on the motor body 1, a mounting hole 21 disposed on the housing 1, the output shaft 3 being disposed inside the housing 1 and extending out from the mounting hole 21, the output shaft 3 being provided with a first recess 31 and a second recess 32, the first recess 31 extending from the free end 33 of the output shaft 3 toward the housing 2, the starting end 34 of the second recess 32 being located on the first recess 31, and a gap being provided between the second recess 32 and the free end 33.

[0014] Furthermore, the depth of the second recess 32 is greater than the depth of the first recess 31.

[0015] Furthermore, the arcuate angle between the beginning end 34 and the end end 37 of the second recess 32 is less than 180 degrees.

[0016] Furthermore, the first recess 31 is provided with a first tail end 35, and the second recess 32 is provided with a second tail end 36, wherein the first tail end 35 and the second tail end 36 are coplanar.

[0017] Furthermore, both the first tail end 35 and the second tail end 36 have gaps between them and the housing 1.

[0018] During installation, first align the output shaft 3 with the mounting port 41 on the accessory 4, and align the first recess 31 with the protrusion 42 of the mounting port 41 and install it to the bottom. Then rotate the accessory 4 or the output shaft 3 so that the protrusion 42 falls on the second recess 32.
