Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of couplings, in particular to a multifunctional bellows coupling. Background Art
[0002] With the rapid development of modern mechanical technology, especially in the industrial field of high precision, high speed and high reliability, the performance of the coupling, as an important component connecting two shafts or shafts and rotating parts, directly affects the transmission efficiency and operation stability of the entire system. The bellows coupling is mainly composed of two hubs and a thin-walled tube (bellows) with a corrugated appearance. The bellows is connected to the two hubs by welding or bonding to realize the power transmission between the two shafts. As a flexible coupling, the bellows coupling can produce a certain elastic deformation during the transmission process, and has the advantages of simple structure, small size, and easy processing and installation. Therefore, it has been widely used in many industrial fields.
[0003] However, when the existing bellows coupling is subjected to torque and axial and radial displacements, its overall stiffness is relatively low, and the bellows is prone to large elastic deformation, which in turn leads to reduced transmission accuracy and uneven torque transmission. Especially when transmitting large torque, the bellows cannot withstand excessive deformation, which in turn affects the torque transmission efficiency. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model provides a multifunctional bellows coupling, which can solve the technical problem that the existing bellows coupling has low overall stiffness when subjected to torque and axial and radial displacements, resulting in reduced transmission accuracy and torque transmission efficiency.
[0005] To achieve the above objectives, the utility model provides the following technical solutions: a multifunctional bellows coupling, comprising two coupling ends, an outer bellows and an inner bellows connected between the two coupling ends, and a reinforcing component arranged between the outer bellows and the inner bellows.
[0006] Preferably, the reinforcement assembly comprises a cylindrical mechanism and a reinforcement hoop, the two ends of the cylindrical mechanism are respectively welded to two coupling ends, and the reinforcement hoop is externally welded to the outside of the cylindrical mechanism.
[0007] Preferably, the cylindrical mechanism includes a plurality of reinforcing rods.
[0008] Preferably, the diameter of the reinforcement hoop is between the outer bellows and the inner bellows.
[0009] Preferably, the diameter of the outer bellows is greater than the diameter of the inner bellows.
[0010] Preferably, both ends of the outer bellows and the inner bellows are respectively welded to the side surfaces of the two coupling ends.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] (1) The utility model provides a multifunctional bellows coupling, which improves the overall stiffness of the bellows coupling by arranging a reinforcing component between the outer bellows and the inner bellows. When torque acts on the coupling, the reinforcing component can bear part of the torque, thereby reducing the deformation of the bellows and improving the transmission accuracy and torque transmission efficiency.
[0013] (2) The utility model provides a multifunctional bellows coupling. By arranging two layers of bellows, an outer bellows and an inner bellows, the bellows has more deformable parts, thereby increasing the variability adjustment range of the bellows coupling, thereby ensuring that the bellows coupling can maintain a certain degree of elastic deformation while meeting the stiffness requirements.

[0020] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of this application.
[0021] like Figure 1-5As shown, the utility model provides a multifunctional bellows coupling, including two coupling ends 1, an outer bellows 2 and an inner bellows 3 connected between the two coupling ends 1, the outer bellows 2 is sleeved on the outside of the inner bellows 3, and a gap is left between the outer bellows 2 and the inner bellows 3. A reinforcing component 4 is provided between the outer bellows 2 and the inner bellows 3, and the reinforcing component 4 is specifically sleeved on the outside of the inner bellows 3 and located in the gap between the outer bellows 2 and the inner bellows 3. A gap is left between the reinforcing component 4 and the outer bellows 2, and a gap is also left between the reinforcing component 4 and the inner bellows 3, providing deformation space for the outer bellows 2 and the inner bellows 3. The reinforcing component 4 includes a cylindrical mechanism 41 and a reinforcing hoop 42, the reinforcing hoop 42 is sleeved on the outer periphery of the cylindrical mechanism 41 and inscribed in the cylindrical mechanism 41, and the two ends of the cylindrical mechanism 41 are respectively welded to the two coupling ends 1. The cylindrical mechanism 41 is surrounded by four parallel reinforcing rods 411, and the two ends of the reinforcing rods 411 are respectively welded to the two coupling ends 1. In order to further increase the rigidity of the cylindrical mechanism 41, two or more reinforcing hoops 42 can be set on the outer circumference of the cylindrical mechanism 41. The diameter of the reinforcing hoop 42 is smaller than the inner diameter of the outer bellows 2 and larger than the outer diameter of the inner bellows 3, so that even if the reinforcing assembly 4 is set between the outer bellows 2 and the inner bellows 3, the outer bellows 2 and the inner bellows 3 can have sufficient deformation space. The two ends of the outer bellows 2 and the inner bellows 3 are respectively welded to the sides of the two coupling ends 1.
[0022] Specifically, the overall stiffness of the bellows coupling is improved by setting a reinforcing component 4, and by setting two layers of bellows, the outer bellows 2 and the inner bellows 3, when torque acts on the bellows coupling, the outer bellows 2 and the inner bellows 3 will elastically deform at the same time, and the torque is transmitted by bending and stretching the bellows. Since there is a reinforcing component 4 between the outer bellows 2 and the inner bellows 3, the overall stiffness of the coupling can be effectively enhanced, so that it can maintain good stability and reliability when transmitting torque. At the same time, the design of the inner and outer layers of bellows increases the variability adjustment range of the coupling, so that it can better adapt to the slight deviation and misalignment between the shafts. In the process of torque transmission, the outer bellows 2 and the inner bellows 3 can jointly bear and disperse the torque load, thereby ensuring that the bellows coupling can maintain a certain degree of elastic deformation while meeting the stiffness requirements.
[0023] The utility model adopts a structure in which a layer of bellows is provided inside and outside, and a reinforcing component 4 is provided between the two layers of bellows. Compared with a structure in which only one layer of bellows is combined with a reinforcing component 4, the utility model provides a reinforcing component 4 between the outer bellows 3 and the inner bellows 2, thereby improving the overall stiffness of the bellows coupling. The two layers of bellows, the outer bellows 3 and the inner bellows 2, provide the bellows with more deformable parts, thereby avoiding relying on only one layer of bellows to withstand torque and displacement, which results in uneven deformation of the bellows. When the force is uneven, due to the presence of the reinforcing component 4 and the structure in which only one layer of bellows is provided, some areas of the bellows may be subjected to excessive stress, while other areas may be subjected to insufficient stress. This uneven deformation may affect the normal operation of the coupling and may cause additional stress and wear. The utility model increases the variability adjustment range of the bellows coupling, thereby ensuring that the bellows coupling can maintain a certain degree of elastic deformation while meeting the stiffness requirements.
[0024] During installation, first, weld each reinforcing rod 411 evenly to the inner wall of the reinforcing hoop 42 to form a reinforcing assembly 4, then sleeve the reinforcing assembly 4 on the outer periphery of the inner bellows 2, and then sleeve the processed outer bellows 3 on the outer periphery of the reinforcing assembly 4, and finally weld the assembled outer bellows 3, inner bellows 2 and reinforcing assembly 4 to both ends of the two coupling ends 1. Pay attention to the gap between the outer bellows 3, inner bellows 2 and reinforcing assembly 4 during welding.
[0025] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For technicians in the technical field to which the present invention belongs, several equivalent substitutions or obvious variations can be made without departing from the concept of the present invention, and the performance or use is the same, which should be regarded as belonging to the protection scope of the present invention.
