Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor technology, and in particular to a motor assembly. Background Technology
[0002] In micro and small geared motor applications, if the output shaft is only connected to a suspended load that is not additionally secured, when the load is subjected to impacts such as vibration or drops, the load's kinetic energy will be directly transferred to the motor's interior through the output shaft. This can potentially damage internal motor components such as gears, affecting gear meshing, and ultimately leading to impaired or even failed motor functionality. Utility Model Content
[0003] In view of the above-mentioned existing situation, this application provides a motor assembly that can reduce the transmission of vibration into the motor.
[0004] This utility model provides a motor assembly, including: a housing having an accommodating groove and a limiting groove that are interconnected; a motor body disposed in the accommodating groove, with the output end of the motor body facing the limiting groove; an output shaft connected to the output end of the motor body, the output shaft passing through the outside of the housing and connected to an external load; and a bearing, the output shaft passing through the bearing, the bearing being located in the limiting groove, and the inner contour of the limiting groove matching the outer contour of the bearing.
[0005] Optionally, the bearing has a first protrusion on its circumference, the first protrusion is located in the limiting groove, and the outer contour of the first protrusion matches the outer contour of the limiting groove.
[0006] Optionally, a second protrusion is provided on the periphery of the output shaft, and the second protrusion is located between the first protrusion and the motor body.
[0007] Optionally, the output end of the motor body is provided with a socket; the output shaft is inserted into the socket.
[0008] Optionally, the housing includes a first housing and a second housing, which are detachably connected.
[0009] Optionally, the first housing and the second housing are snap-fitted or threaded together.
[0010] Optionally, the bearing includes one of oilless bearings, oil-impregnated bearings, and ball bearings.
[0011] Optionally, the output shaft is bonded or threaded to an external load.
[0012] The motor assembly of this utility model includes a housing, a motor body, an output shaft, and a bearing. The housing has interconnected receiving grooves and limiting grooves; the motor body is disposed within the receiving grooves, with its output end facing the limiting grooves; the output shaft is connected to the output end of the motor body, extending through the housing and connecting to an external load; the output shaft passes through the bearing, which is located within the limiting grooves, and the inner contour of the limiting grooves matches the outer contour of the bearing. Thus, the limiting grooves can limit the bearing's position. When the load is subjected to vibration or impact such as a drop, the vibration is transmitted to the output shaft and bearing. The vibrating bearing contacts the inner wall of the limiting grooves, allowing the bearing and housing to absorb the vibration, reducing its further transmission into the motor body, thereby improving the stability and durability of the motor body. Furthermore, the limiting grooves prevent the load from swaying axially when subjected to external impacts, thus improving the overall structural stability. Attached Figure Description

[0021] The preferred embodiments of this application will now be described in detail with reference to the accompanying drawings. In the following description, the same reference numerals are used for the same components, and repeated descriptions are omitted. Furthermore, the drawings are merely schematic diagrams, and the proportions of the components or their shapes may differ from actual dimensions. It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationships and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.
[0022] It should also be noted that when a component is described as "fixed to" or "set on" another component, it can be directly on the other component or there may be an intervening component present. When a component is described as "connected to" another component, it can be directly connected to the other component or there may be an intervening component present.
[0023] Reference Figures 1 to 4 This application provides a motor assembly, which includes a housing 1, a motor body 2, an output shaft 3, and a bearing 4. The housing 1 has an interconnected receiving groove 11 and a limiting groove 12; the motor body 2 is disposed within the receiving groove 11, with its output end facing the limiting groove 12; the output shaft 3 is connected to the output end of the motor body 2, extends through the housing 1, and is connected to an external load 100; the output shaft 3 passes through the bearing 4, and the bearing 4 is located within the limiting groove 12, with the inner contour of the limiting groove 12 matching the outer contour of the bearing 4.
[0024] According to the above structure, in the motor assembly provided in this application, the limiting groove 12 can limit the bearing 4. When the load 100 is subjected to impacts such as vibration or drop, the vibration will be transmitted to the output shaft 3 and the bearing 4. The vibrating bearing 4 contacts the inner wall of the limiting groove 12, allowing the bearing 4 and the housing 1 to absorb the vibration, thereby reducing the continued transmission of vibration into the motor body 2, and thus improving the stability and durability of the motor body 2. In addition, due to the setting of the limiting groove 12, the load 100 will not wobble axially when subjected to external impacts, thereby improving the overall structural stability.
[0025] Reference Figure 5 In some embodiments, the bearing 4 has a first protrusion 41 on its circumference, which is located within the limiting groove 12, and the outer contour of the first protrusion 41 matches the outer contour of the limiting groove 12. Thus, the limiting groove 12 can adequately limit the movement of the first protrusion 41. Specifically, there is a gap between the first protrusion 41 and the inner wall of the limiting groove 12, preventing them from completely fitting together.
[0026] Reference Figure 4 and Figure 5 In some embodiments, a second protrusion 42 is provided on the periphery of the output shaft 3, and the second protrusion 42 is located between the first protrusion 41 and the motor body 2. Thus, the first protrusion 41 can limit the second protrusion 42, restricting the output shaft 3 from moving in the axial direction and preventing the output shaft 3 from detaching from the motor body 2.
[0027] Reference Figure 3 In some embodiments, the output end of the motor body 2 is provided with a socket 21; the output shaft 3 is inserted into the socket 21. Specifically, the output shaft 3 is an externally mounted output shaft 3. During installation, the output shaft 3 can be directly inserted into the socket 21. Due to the cooperation between the first protrusion 41 and the second protrusion 42, the output shaft 3 will not disengage from the socket 21 during operation, and there can be a certain gap between the output shaft 3 and the socket 21. Therefore, when the external load 100 is subjected to vibration, the externally mounted output shaft 3 can reduce the direct impact on the motor body 2, and the bearing 4 has already borne most of the vibration, so the vibration received by the motor body 2 is minimal.
[0028] In some embodiments, housing 1 includes a first housing 13 and a second housing 14, which are detachably connected. Therefore, when the motor assembly suffers damage to internal components due to impacts such as vibration or drops, housing 1 can be quickly opened for inspection and replacement, greatly saving maintenance time and costs.
[0029] In some embodiments, the first housing 13 and the second housing 14 are snap-fitted or threaded together. The first housing 13 may have a locking block, and the second housing 14 may have a locking groove. The engagement of the locking block and the locking groove allows the first housing 13 and the second housing 14 to connect. The snap-fit connection facilitates later disassembly and repair, allowing users to quickly open the housing 1 for inspection and replacement of internal components, improving maintenance efficiency. Alternatively, the first housing 13 and the second housing 14 can also be threaded together. Threaded connections offer higher connection strength and sealing, making the connection between the first housing 13 and the second housing 14 more secure and effectively preventing the housing 1 from loosening due to vibration or impact.
[0030] In some embodiments, the bearing 4 includes one of an oilless bearing 4, an oil-impregnated bearing 4, and a ball bearing 4. Specifically, the user can select the type of bearing 4 according to their needs. Specifically, an oilless bearing 4 can be selected, which has the advantages of lower cost, higher precision, and longer life.
[0031] In some embodiments, the output shaft 3 is bonded or threaded to the external load 100. This further improves the connection stability between the output shaft 3 and the external load 100.
[0032] In some embodiments, a reduction gearbox 22 is also provided on one side of the motor body 2, wherein the insertion hole 21 is provided at the output end of the reduction gearbox 22, and the output shaft 3 is inserted at the output end.
[0033] Specifically, during the installation of the motor assembly provided in this application, the output shaft 3 can be inserted into the inner ring of the bearing 4 first, and then the external load 100 can be inserted into the output shaft 3. The end of the output shaft 3 facing away from the external load 100 can then be inserted into the insertion hole 21 of the gearbox 22. Finally, the first housing 13 and the second housing 14 are installed, so that the motor body 2, the gearbox 22, and the intermediate bearing 4 are enclosed within the first housing 13 and the second housing 14.
[0034] In summary, in the motor assembly provided in this application, the limiting groove 12 can limit the bearing 4. When the load 100 is subjected to impacts such as vibration or drop, the vibration will be transmitted to the output shaft 3 and the bearing 4. The vibrating bearing 4 contacts the inner wall of the limiting groove 12, allowing the bearing 4 and the housing 1 to absorb the vibration, thereby reducing the continued transmission of vibration into the motor body 2, and thus improving the stability and durability of the motor body 2. In addition, due to the setting of the limiting groove 12, the load 100 will not wobble axially when subjected to external impacts, thereby improving the overall structural stability.
