Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor technology, and in particular to a shock-absorbing motor. Background Technology
[0002] An electric motor is an electrical device that converts electrical energy into mechanical energy, widely used in industry, transportation, and household appliances. It works by using the principle of electromagnetic induction, where current flowing through a coil generates a rotating magnetic field, which in turn drives a rotor to rotate. There are many types of electric motors, including DC motors, AC motors, and stepper motors, each with its specific applications and advantages. DC motors are known for their excellent control performance and high efficiency, while AC motors are widely used due to their simple structure and ease of maintenance. Stepper motors, with their precise stepping control capabilities, play a crucial role in precision positioning systems. Motor selection requires consideration of parameters such as power, speed, and torque to meet different application requirements.
[0003] Similarly, electric motors are widely used in textile equipment, powering a variety of textile machinery such as spinning machines, weaving machines, knitting machines, dyeing machines, printing machines, and finishing machines. These motors typically need to be high-performance to ensure precise control and high-speed operation, while maintaining reliability to cope with the continuous operation and harsh conditions in textile production.
[0004] When electric motors are used in textile equipment, the structure driven by the motor's rotor shaft often causes unnecessary shaking of the rotor shaft, which in turn causes the entire motor to vibrate. Once the motor starts to vibrate, the fasteners between the motor and the equipment it is attached to will loosen, eventually leading to separation.
[0005] Therefore, a vibration-damping motor is proposed to solve or alleviate the above problems. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a shock-absorbing motor.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A vibration damping motor includes a housing, a rotor shaft rotatably connected within the housing, and an end cover detachably connected to the end of the housing. A circumferential vibration damping assembly is disposed within the end cover. A support shaft is rotatably connected to the end of the rotor shaft away from the housing. The support shaft is detachably connected within the circumferential vibration damping assembly. The circumferential vibration damping assembly has elastic deformation properties in its radial direction.
[0009] Preferably, the circumferential damping assembly includes a support layer, several buffer components, and a connecting plate disposed within the end cover. The support layer is annular, and the inner ring of the support layer has several evenly spaced and inwardly recessed grooves. The connecting plate is laid on the support layer, and the buffer components connect the connecting plate and the end cover. The support shaft is fixedly connected within the connecting plate.
[0010] Preferably, the inner ring of the connecting disc has a slot that extends through its thickness direction, and the outer ring of the support shaft is integrally formed with a locking block that can be embedded in the slot. The inner diameter of the connecting disc is the same as the outer diameter of the support shaft.
[0011] Preferably, both the support layer and the buffer have hardness and elastic deformation properties, and the hardness of the support layer is greater than that of the buffer.
[0012] Preferably, the support layer is made of DV material.
[0013] Preferably, the buffer includes a rubber block embedded in the groove, and the rubber block is made of rubber.
[0014] Preferably, the thickness of the adhesive block is greater than or equal to the thickness of the support layer.
[0015] Preferably, the buffer further includes a concave connector and a convex connector. The top surface of the rubber block has a downwardly recessed, T-shaped upper groove, and the bottom surface of the rubber block has a disc-shaped lower groove. The concave connector is T-shaped, and the top surface of the concave connector has a threaded groove. The concave connector is fixedly connected to the upper groove. The convex connector includes a disc portion and a screw portion. The disc portion is fixedly connected to the lower groove. The disc portion has a through hole, and a connecting bolt threaded into the through hole and connected to the threaded groove is threaded through the through hole. The screw portion passes through the end cap and is threadedly connected to a connecting nut.
[0016] This utility model has the following beneficial effects:
[0017] In actual operation, after the stator winding is energized, the rotor shaft drives the rotor to rotate, which in turn drives the rotor shaft to rotate. Since the rotor shaft is rotatably connected to the housing and its other end is rotatably connected to the support shaft, the end of the rotor shaft away from the housing is also supported by the support shaft, allowing for smooth rotation. When the end of the rotor shaft connected to the textile equipment causes vibration, the vibration is transmitted to the connecting plate through the support shaft. The connecting plate then transmits the vibration to the buffer components via connecting bolts. The rubber blocks in the buffer components have good elastic deformation properties, so multiple buffer components can reduce or even eliminate the vibration transmitted from the support shaft in the radial direction of the support layer. This prevents the vibration on the rotor shaft from being further transmitted to the entire motor, avoiding loosening or even detachment of the connection between the motor and the attached equipment due to vibration.

[0031] A type of vibration damping motor, such as Figure 1 and Figure 2As shown, it includes a housing 1, a rotor shaft 2 rotatably connected inside the housing 1, and an end cover 3 detachably connected to the end of the housing 1. A circumferential damping assembly is provided inside the end cover 3. A support shaft is rotatably connected to the end of the rotor shaft 2 away from the housing 1. The support shaft is detachably connected inside the circumferential damping assembly. The circumferential damping assembly has elastic deformation properties in its radial direction.
[0032] like Figures 3 to 5 As shown, the circumferential damping assembly includes a support layer 4, several buffers 6, and a connecting plate 7 disposed within the end cap 3. The support layer 4 is annular, and the inner ring of the support layer 4 has several evenly spaced and inwardly recessed grooves 5. The connecting plate 7 is laid on the support layer 4, and the buffers 6 connect the connecting plate 7 and the end cap 3. The support shaft is fixedly connected within the connecting plate 7. Specifically, the inner ring of the connecting plate 7 has a slot 701 that extends through its thickness direction, and the outer ring of the support shaft is integrally formed with a locking block 201 that can be embedded in the slot 701. The inner diameter of the connecting plate 7 is the same as the outer diameter of the support shaft.
[0033] Both the support layer 4 and the buffer 6 have hardness and elastic deformation properties. The hardness of the support layer 4 is greater than that of the buffer 6. The support layer 4 is made of DV material.
[0034] The buffer 6 includes a rubber block 601 embedded in the groove 5, a concave connector 603, and a convex connector 605. The rubber block 601 is made of rubber and its thickness is greater than or equal to the thickness of the support layer 4. The top surface of the rubber block 601 has a downwardly recessed T-shaped upper groove 602, and the bottom surface of the rubber block 601 has a disc-shaped lower groove 604. The concave connector 603 is T-shaped and has a threaded groove on its top surface. The concave connector 603 is fixedly connected to the upper groove 602. The convex connector 605 includes a disc part and a screw part. The disc part is fixedly connected to the lower groove 604. The connecting disc 7 has a through hole 702, and a connecting bolt 8 that is threadedly connected to the threaded groove passes through the through hole 702. The screw part passes through the end cap 3 and is threadedly connected to a connecting nut 9.
[0035] When this utility model is working, after the stator winding in the motor is energized, the rotor drives the rotor shaft 2 to rotate, and then the rotor shaft 2 rotates as well. Since the rotor shaft 2 is rotatably connected inside the housing 1 and one end is connected to the support shaft, the shaft end away from the housing 1 is supported, thus achieving stable operation.
[0036] If the rotor shaft 2 vibrates due to its connection with the textile equipment, the vibration is transmitted to the connecting plate 7 via the support shaft, and then to the buffer 6 via the connecting bolt 8. The rubber block 601 inside the buffer 6 effectively absorbs and reduces the radial vibration transmitted from the support shaft due to its excellent elasticity, preventing the vibration from spreading to the entire motor, thereby avoiding loosening or detachment of the motor and equipment connection caused by vibration.
[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
