Description

Technical Field

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

[0002] The clutch, a crucial mechanical transmission device, plays a vital role in mechanical systems. Its primary function is to connect and disconnect a power source (such as an engine or electric motor) from a driven device (such as a transmission or working mechanism). During power transmission, the clutch can smoothly engage or disengage as needed, controlling the transmission and interruption of power. When engaged, the clutch ensures that the torque generated by the power source is effectively transmitted to the driven device, driving the mechanical equipment to operate normally. When power transmission needs to be interrupted, the clutch can quickly and smoothly disengage, avoiding impact and damage to the mechanical equipment. The clutch also has overload protection. When the mechanical equipment encounters excessive resistance or torque during operation, the clutch can automatically slip, protecting the equipment from damage. Existing clutches have relatively complex structures and poor stability during power transmission, affecting their transmission performance. Therefore, improvements are needed to the existing clutch structure for power transmission. Utility Model Content

Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0022] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. Figures 1-4As shown, in one embodiment of this utility model, a clutch is disclosed, including a housing 1, a rotary connecting element 2, a floating connecting element 3, and a drive connecting element 4. The housing 1 is provided with a rotary mounting cavity 5, and an output connecting part 11 is provided on one side of the housing 1. One end of the output connecting part 11 is connected to the rotary mounting cavity 5. The drive connecting element 4 is rotatably mounted in the rotary mounting cavity 5 via the rotary connecting element 2. The floating connecting element 3 is mounted in the rotary mounting cavity 5 and one end abuts against the drive connecting element 4 to provide floating support force when the drive connecting element 4 rotates in the rotary mounting cavity 5. The drive connecting element 4 is provided with an input connecting part 41 and a drive connecting part 42. The input connecting part 41 is used to connect to a power source, and the drive connecting part 42 is used to connect to the output connecting part 11 to drive the housing 1 to rotate. This embodiment provides a stable and protected working environment for the drive connecting element 4, the rotary connecting element 2, and the floating connecting element 3 by providing a rotary mounting cavity 5 in the housing 1, effectively reducing the interference of the external environment on the internal transmission components and improving the durability and service life of the clutch. Secondly, the drive connecting element 4 rotates flexibly within the rotating housing 5 via the rotating connecting element 2. This design not only ensures smooth power transmission but also allows the clutch to maintain stable operation even under high torque. Simultaneously, the rotating connecting element 2, acting as a transmission intermediary, further enhances the clutch's transmission efficiency and response speed. Furthermore, one end of the floating connecting element 3 abuts against the drive connecting element 4, providing necessary floating support force as the drive connecting element 4 rotates. This not only optimizes the force distribution during transmission and reduces wear between components but also significantly improves the clutch's vibration absorption capacity and operational smoothness. In addition, the input connecting part 41 and the drive connecting part 42 on the drive connecting element 4 are responsible for connecting the power source and the output connecting part 11, respectively, achieving efficient power transmission and conversion. The standardized design of the input connecting part 41 facilitates quick docking with various power sources, while the tight cooperation between the drive connecting part 42 and the output connecting part 11 ensures that the housing 1 can rotate synchronously with the drive connecting element 4, thus meeting the transmission requirements under complex working conditions. This embodiment achieves a comprehensive improvement in transmission efficiency, durability, and operational stability through a floating support mechanism, providing efficient and reliable transmission for various mechanical equipment.

[0024] The outer casing 1 includes a first housing 12 and a second housing 13, which are connected. A rotary mounting cavity 5 is disposed between the first housing 12 and the second housing 13. An output connection portion 11 is provided on the first housing 12 and / or the second housing 13, and the output connection portion 11 is coaxial with and opposite to the drive connection element 4. Specifically, the first housing 12 is provided with a first connecting ring 121, and the second housing 13 is provided with a second connecting ring 131. The first connecting ring 121 and the second connecting ring 131 are provided with connecting holes opposite to each other, and the first connecting ring 121 and the second connecting ring 131 are connected to each other through the connecting holes. In this embodiment, firstly, the connection between the first housing 12 and the second housing 13 forms a stable and reliable rotary mounting cavity 5, which provides precise positioning and a stable operating environment for the core transmission components of the clutch. Secondly, the design of the output connection portion 11 achieves a coaxial and relative layout with the drive connection element 4, which not only optimizes the transmission path but also significantly improves the transmission efficiency and response speed of the clutch. This design ensures the accuracy and continuity of power transmission, thereby improving the overall performance of the equipment. Furthermore, the interconnection of the first connecting ring 121 and the second connecting ring 131 via connecting holes not only simplifies the assembly process but also enhances the overall strength and stability of the housing 1. This connection method effectively resists external impacts and vibrations, extending the service life of the clutch.

[0025] The rotary connecting element 2 consists of multiple rolling elements. A rolling connecting groove 43 is provided on the outer periphery of the driving connecting element 4. The multiple rolling elements are evenly distributed circumferentially on the rolling connecting groove 43, with one end of each rolling element rolling against the wall of the rotary mounting cavity 5. Specifically, the rolling elements are rolling cylinders or steel balls. In this embodiment, the rolling cylinders or steel balls, as rolling elements, have extremely low friction coefficients and excellent wear resistance, which can significantly reduce energy loss during clutch rotation and improve transmission efficiency. Simultaneously, the rolling contact method, compared to sliding contact, reduces frictional heat generation and extends the clutch's service life. Secondly, the circumferentially distributed design of the rolling elements ensures the uniformity and stability of the rotary connecting element 2 under stress. This design helps reduce vibration and noise caused by uneven stress, improving the overall performance of the clutch. Furthermore, the rolling connecting groove 43 provides reliable positioning and support for the rolling elements, preventing them from falling off or misaligning during rotation, further enhancing the clutch's reliability and safety.

[0026] The floating connecting element 3 is an elastic element, with one side abutting against the wall of the rotary mounting cavity 5 and the other side abutting against the drive connecting element 4. In this embodiment, the elastic design of the floating connecting element 3 can automatically adapt to these minute positional changes, ensuring a stable connection between the drive connecting element 4 and the rotary mounting cavity 5, avoiding connection failure due to positional misalignment, thereby improving the overall reliability of the clutch. The elastic element of the floating connecting element 3 can absorb and buffer some impacts and vibrations, reducing wear on other clutch components, thereby extending the clutch's service life. Specifically, when a power source input is received, the drive connecting part 42 will connect with the output connecting part 11 under the action of the floating connecting element 3 to ensure a stable output connection.

[0027] The wall of the rotating mounting cavity 5 is provided with a first floating abutment groove 51, and a first abutment ring 52 is provided on the first floating abutment groove 51. Second floating abutment grooves 44 are provided on both sides of the drive connecting element 4, and second abutment rings 441 are provided on the second floating abutment grooves 44. The floating connecting element 3 is a wave-shaped spring sheet, with its two ends abutting against the first abutment ring 52 and the second abutment ring 441 respectively. In this embodiment, the cooperation between the first floating abutment groove 51 and the first abutment ring 52, and the second floating abutment groove 44 and the second abutment ring 441, not only ensures the stability of the connection but also ensures wear resistance. The abutment ring is made of wear-resistant metal, thereby extending its service life. As a floating connecting element 3, the unique wave structure of the wave-shaped spring sheet gives the clutch excellent elasticity and compensation capability. The two ends of the wave spring abut against the first abutment ring 52 and the second abutment ring 441 respectively, which can absorb and alleviate stress caused by manufacturing errors, assembly tolerances, or minor deformations during operation to a certain extent, thereby ensuring the smoothness and reliability of clutch transmission. The elastic compensation effect of the wave spring can effectively reduce wear and impact between components, reduce the failure rate of the clutch, and extend the maintenance cycle of the overall system.

[0028] An input connection portion 41 is located at the shaft center of the drive connection element 4. The input connection portion 41 has an input connection hole 411, and an input connection thread 412 is provided on the input connection hole 411. In this embodiment, the input connection portion 41 at the shaft center ensures the accuracy and stability of power transmission, effectively reducing energy loss and wear caused by connection deviations, thereby improving the overall transmission efficiency and service life of the clutch. Secondly, the design of the input connection hole 411 and its thread provides a convenient and reliable connection method. This connection method not only facilitates installation and maintenance but also effectively prevents the connecting parts from loosening or falling off during use, enhancing the safety and reliability of the clutch.

[0029] The drive connection part 42 is provided with a drive gear ring 421, and the output connection part 11 is provided with an internal gear ring 111. The drive gear ring 421 is used to mesh with the internal gear ring 111. Specifically, a first chamfer 422 is provided at the end of the drive gear ring 421, and a second chamfer 112 is provided at the end of the internal gear ring 111 facing the drive gear ring 421. The chamfers are used for guiding during meshing. In this embodiment, the drive gear ring 421 configured in the drive connection part 42 and the internal gear ring 111 of the output connection part 11 cooperate with each other to form a precise and efficient transmission mechanism. The drive gear ring 421 is specially designed to achieve precise meshing with the internal gear ring 111. This structure not only ensures stable power transmission but also greatly improves the overall performance of the clutch. In particular, the first chamfer 422 at the end of the drive gear ring 421 and the second chamfer 112 at the end of the internal gear ring 111 facing the drive gear ring 421 together play a key guiding role. During clutch engagement, these two chamfers guide the gear rings to gradually and smoothly enter their meshing positions, effectively avoiding impact and wear caused by direct, hard contact. This not only extends the clutch's service life but also significantly improves its reliability and stability. By optimizing the engagement process, power loss due to improper engagement is reduced, ensuring the clutch can continuously and efficiently transmit power.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
