Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a clutch motor. Background Technology

[0002] A clutch motor is a type of motor that can switch between electric and manual operation. It mainly consists of a motor and a transmission component. The output shaft of the motor is connected to the transmission component through a clutch device. However, the existing clutch devices are very complex in structure, and most clutch devices require a shift lever to change gears when switching between manual and electric operation, which results in inconvenience in operation. Utility Model Content

[0003] The purpose of this invention is to provide a clutch motor. This invention is an electric motor with built-in clutch output, which eliminates the need for gear shifting using a shift lever. It has the advantages of simple and compact structure and convenient operation.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a clutch motor, comprising a motor body, a clutch device, and a transmission component. The motor body is provided with a motor shaft, and the transmission component is rotatably mounted on the motor shaft. The motor shaft is connected to the transmission component through the clutch device. The clutch device includes a drive disc linked to the outer periphery of the motor shaft, a clutch disc rotatably mounted on the outer periphery of the motor shaft, a pusher structure for pushing the clutch disc toward the direction closer to the transmission component when the drive disc rotates, thereby causing the clutch disc to engage with the transmission component, and a reset component for driving the clutch disc toward the direction away from the transmission component when the drive disc stops rotating, thereby causing the clutch disc to separate from the transmission component.

[0005] By adopting the above technical solution, when the motor is rotating, the clutch is engaged, and the transmission components work under the drive of the motor. When the motor stops, the clutch disengages through the action of the reset component, disconnecting the transmission components from the motor shaft and automatically switching to manual mode. Its electric self-clutch output eliminates the need for gear shifting using a lever, offering advantages such as simple and compact structure and convenient operation.

[0006] The present invention is further configured such that the pushing structure includes a plurality of balls disposed between the drive disc and the clutch disc, and the end face of the drive disc is provided with a plurality of first conical grooves for the balls to be partially embedded, and the end face of the clutch disc is provided with a plurality of second conical grooves for the other part of the balls to be embedded.

[0007] By adopting the above technical solution, the conical groove can provide guidance for the ball bearings. When the drive disc rotates, the ball bearings tend to disengage from the first and second conical grooves, causing the clutch disc to move axially and cooperate with the transmission component. When the drive disc stops rotating, the linkage disc retracts under the action of the reset component, and the ball bearings re-embed into the first and second conical grooves.

[0008] The present invention is further configured such that the reset component includes a spring, the spring is sleeved on the outer periphery of the motor shaft, and the two ends of the spring respectively abut against the transmission component and the clutch disc.

[0009] By adopting the above technical solution and using a spring as the reset component, it has the advantages of simple structure and easy assembly.

[0010] The present invention is further configured such that the clutch disc is provided with a first positioning groove for embedding one end of the spring, and the transmission component is provided with a second positioning groove for embedding the other end of the spring.

[0011] By adopting the above technical solution, the spring can be positioned and installed, improving its stability during installation and movement, preventing deformation that deviates from the central axis, and thus extending its service life.

[0012] The present invention is further configured such that the clutch disc and the transmission component achieve linkage through a structure in which protrusions and grooves cooperate.

[0013] By adopting the above technical solution, the fitting method is simple and reliable, and can achieve circumferential linkage when fitting, making processing very convenient.

[0014] The present invention is further configured to include a damping element for applying frictional force to the clutch disc.

[0015] By adopting the above technical solution, damping is applied to the clutch disc, which ensures that when the drive disc rotates, the clutch disc can be pushed out by the balls, thus avoiding the direct rotation of the balls and clutch disc when the drive disc rotates, which would prevent the clutch disc from axially displacing.

[0016] The present invention is further configured such that the damping component includes a connecting part located in the middle and abutting parts provided at both ends of the connecting part, the motor body is provided with an adjusting screw, the clutch disc is provided with an annular groove on its outer periphery, the connecting part overlaps with the adjusting screw, and the two abutting parts abut against both ends of the annular groove and apply a preload force to the clutch disc.

[0017] By adopting the above technical solution, the damping component can effectively provide damping for the clutch disc. Its structure is reliable and easy to process and assemble.

[0018] The present invention is further configured such that a bushing is fitted around the outer periphery of the motor shaft, the inner end of the bushing abuts against the outer end of the drive disc, the clutch disc is rotatably mounted on the outer periphery of the bushing, a locking nut is threadedly connected to the outer end of the motor shaft, a washer is sandwiched between the locking nut and the bushing, and an annular limiting groove is provided at one end of the outer circular surface of the bushing near the washer, and an annular limiting flange is provided on the transmission component to cooperate with the annular limiting groove.

[0019] By adopting the above technical solution, the transmission components can be positioned and installed, and the bushing can reduce the wear of the motor shaft and clutch disc, thereby improving the overall service life. Attached Figure Description

[0026] 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.

[0027] Example: As attached Figures 1-5The clutch motor shown includes a motor body 1, a clutch device 2, and a transmission component 3. The motor body 1 is provided with a motor shaft 4, and the transmission component 3 is rotatably mounted on the motor shaft 4. The motor shaft 4 is connected to the transmission component 3 through the clutch device 2. In this embodiment, the transmission component 3 is a gear. Alternatively, depending on the design requirements, the transmission component 3 can be a sprocket or a pulley. The clutch device 2 includes a drive disc 5 (which can be connected by a key) that is linked to the outer periphery of the motor shaft 4, a clutch disc 6 that is rotatably mounted to the outer periphery of the motor shaft 4, a pusher structure 7 that pushes the clutch disc 6 toward the direction closer to the transmission component 3 when the drive disc 5 rotates, and causes the clutch disc 6 to engage with the transmission component 3, and a reset component 8 that drives the clutch disc 6 toward the direction away from the transmission component 3 when the drive disc 5 stops rotating, and causes the clutch disc 6 to separate from the transmission component 3. When the motor is rotating, the clutch 2 is engaged, and the transmission component 3 operates under the motor's drive. When the motor stops, the clutch 2 disengages through the reset component 8, disconnecting the transmission component 3 from the motor shaft 4 and automatically switching to manual mode, at which point the transmission component 3 is in an idling state. Its electric self-clutch output eliminates the need for gear shifting using a lever, offering advantages such as simple and compact structure and convenient operation.

[0028] As attached Figure 2 As shown, the pushing structure 7 includes multiple balls 9 disposed between the drive disk 5 and the clutch disk 6. The drive disk 5 has multiple first conical grooves 10 on its end face for partially embedding the balls 9, and the clutch disk 6 has multiple second conical grooves 11 on its end face for partially embedding the balls 9. The conical grooves provide guidance for the balls 9. When the drive disk 5 rotates, the balls 9 tend to disengage from the first and second conical grooves 10 and 11, causing the clutch disk 6 to axially displace and engage with the transmission component 3. When the drive disk 5 stops rotating, the clutch disk retracts under the action of the reset component 8, and the balls 9 re-embed into the first and second conical grooves 10 and 11.

[0029] As attached Figure 2 As shown, the reset component 8 includes a spring 12, which is sleeved on the outer circumference of the motor shaft 4, and both ends of the spring 12 abut against the transmission component 3 and the clutch disc 6, respectively. Using the spring 12 as the reset component 8 has the advantages of simple structure and easy assembly.

[0030] As attached Figure 2 As shown, the clutch disc 6 is provided with a first positioning groove 13 for one end of the spring 12 to be inserted, and the transmission component 3 is provided with a second positioning groove 14 for the other end of the spring 12 to be inserted. This design can position and install the spring 12, improve its stability during installation and movement, prevent it from deforming off the central axis, and thus extend its service life.

[0031] As attached Figure 4 As shown, the clutch disc 6 and the transmission component 3 achieve linkage through the cooperation of protrusions 15 and grooves 16. That is, the clutch disc 6 is provided with multiple protrusions 15, and the transmission component 3 is provided with multiple grooves 16 that cooperate with the protrusions 15. The protrusions 15 and grooves 16 can also be interchanged. This cooperation method is simple and reliable, and can achieve circumferential linkage when engaged, making it very convenient to process.

[0032] As attached Figures 1-3 As shown, the clutch motor also includes a damping element 17 for applying frictional force to the clutch disc 6. Applying damping to the clutch disc 6 ensures that when the drive disc 5 rotates, the clutch disc 6 can be pushed out by the ball bearings 9, avoiding the drive disc 5 from directly driving the ball bearings 9 and the clutch disc 6 to rotate, which would prevent the clutch disc 6 from axially displacing.

[0033] As attached Figures 1-3 As shown, the damping component 17 includes a connecting portion 18 located in the middle and abutment portions 19 at both ends of the connecting portion 18. The motor body 1 is provided with an adjusting screw 20, and the clutch disc 6 has an annular groove 21 on its outer periphery. The connecting portion 18 overlaps the adjusting screw 20, and the two abutment portions 19 abut against both ends of the annular groove 21 and apply a preload force to the clutch disc 6. The abutment portions 19 can be configured as an arc shape adapted to the curvature of the annular groove 21, and the connecting portion 18 can be C-shaped or U-shaped. This damping component 17 can effectively provide damping for the clutch disc 6, and its structure is reliable and easy to process and assemble.

[0034] As attached Figure 2 As shown, a bushing 22 is fitted around the outer circumference of the motor shaft 4. The inner end of the bushing 22 abuts against the outer end of the drive disc 5. The clutch disc 6 is rotatably mounted on the outer circumference of the bushing 22. A locking nut 23 is threadedly connected to the outer end of the motor shaft 4. A washer 24 is sandwiched between the locking nut 23 and the bushing 22. An annular limiting groove 25 is provided on the outer circumference of the bushing 22 near the washer 24. An annular limiting flange 26 is provided on the transmission component 3 to cooperate with the annular limiting groove 25. This design enables the positioning and installation of the transmission component 3, and the bushing 22 can reduce the wear of the motor shaft 4 and the clutch disc 6, thereby improving the overall service life.
