Description

TECHNICAL FIELD

[0001] The utility model relates to a coupling technical field, concretely relates to a shock -absorbing type coupling. BACKGROUND

[0002] The star elastic coupling is with engineering plastics as elastic element, is suitable for connecting two coaxial transmission shaft systems, the radial movement of star elastic coupling under the action of centrifugal force when high speed operation will accelerate its wear, and the outer shell is added. In addition to being able to prevent dust and store oil, insufficient thinning may cause interference, and too much thinning will weaken the strength of the tooth, and the side gap will be very large. The contact condition of the external tooth is improved, the disadvantages of stress concentration of the straight-tooth tooth end edge extrusion under the condition of angular displacement are avoided, the tooth surface friction and wear condition are improved, noise is reduced, and the maintenance cycle is long. The tooth end of the external tooth sleeve of the star elastic coupling is in the shape of a horn, so it is not suitable for use under high speed and impact load conditions, and it is also not suitable for the connection of vertical shafts. The existing coupling structure is relatively complex, and the buffering, shock absorption and wear resistance are not high, and the bearing torque is not large enough.

[0003] Through retrieval, the patent with patent publication number CN201922156709.1 discloses a star coupling with buffering and shock absorption functions, although the device can buffer the rotating circumferential force when in use by setting several lugs, the lugs are fixed on the upper coupling disc by welding, the lower side of the lug is provided with a buffer pad, the outer circumferential surface of the buffer pad is uniformly provided with eight buffer pad grooves, the buffer pad and the buffer pad groove are integrally formed, the center hole penetrates the upper coupling disc, the buffer pad and the lower coupling disc, three metal lugs are arranged on the upper coupling disc and the lower coupling disc, and the size, position and structure are the same, but the device can only buffer the rotating circumferential force when in use, and cannot buffer the axial force (i.e. the force along the axis direction of the coupling). In many mechanical transmission systems, axial force is common, and if this force cannot be effectively buffered, it may cause damage to the equipment or performance degradation. Since only circumferential force can be buffered, the application range of the coupling is limited. It may not be suitable for transmission systems that need to handle both circumferential and axial forces, which limits its versatility and market potential. UTILITY MODEL CONTENTS

[0004] In view of the deficiencies of the prior art, the utility model provides a shock-absorbing type coupling, which solves the problems raised in the background art.

[0005] The technical problems in the above-mentioned technical solutions of the utility model are solved as follows:

[0006] A shock-absorbing type coupling, comprising a rubber buffer, the two ends of the rubber buffer are respectively provided with a first shaft sleeve and a second shaft sleeve;

[0007] The first shaft sleeve is provided with a first clamping tooth, the second shaft sleeve is provided with a second clamping tooth, the rubber buffer is provided with a first clamping groove and a second clamping groove, and the rubber buffer is limited by being inserted into the first clamping tooth and the second clamping tooth through the first clamping groove and the second clamping groove.

[0008] The first shaft sleeve and the second shaft sleeve are provided with an insertion hole penetratingly arranged on one side, and the first shaft sleeve and the second shaft sleeve are provided with a fixing hole penetratingly arranged on one side, and the fixing hole is provided with a bolt.

[0009] On the basis of the above technical scheme, the utility model further can make improvement as follows.

[0010] Further, the rubber buffer is wavelike and covers the first clamping tooth and the second clamping tooth.

[0011] The beneficial effects of the above further scheme are:

[0012] The wavelike design makes the rubber buffer more effectively absorb and disperse energy when impacted or vibrated. This design increases the contact area and frictional resistance between the rubber buffer and the clamping tooth, thereby improving the damping performance. The wavelike rubber buffer can better adapt to the axial and radial deviations between the transmission shafts. When there is a slight displacement between the transmission shafts, the wavelike design allows the rubber buffer to elastically deform, thereby absorbing the energy generated by the displacement and avoiding excessive impact on the transmission system. Through the wavelike covering design, the rubber buffer can be more tightly fitted on the first clamping tooth and the second clamping tooth, enhancing the connection stability between the components of the coupling. This tight connection helps prevent the coupling from relative rotation or loosening during transmission, thereby ensuring the stability and reliability of the transmission.

[0013] Further, the first shaft sleeve and the second shaft sleeve are respectively provided with an insertion slot corresponding to the second clamping tooth and the first clamping tooth, and the first clamping tooth and the second clamping tooth are axially buffered by the rubber buffer between the second shaft sleeve and the first shaft sleeve.

[0014] The beneficial effects of the above further scheme are:

[0015] The connection between the first shaft sleeve and the second shaft sleeve becomes more stable through the mutual insertion of the teeth and the slots. This design effectively prevents the relative rotation or loosening of the coupling during transmission, thereby ensuring the stability and reliability of the transmission. The rubber buffer is ingeniously designed between the teeth and the slots, not only serving as a circumferential limiting element, but also providing axial buffering. When there is a slight axial displacement between the transmission shafts, the rubber buffer can elastically deform to absorb the energy generated by these displacements, thereby protecting the transmission system from impact. The design of the teeth and the slots makes the installation of the coupling more simple and quick. At the same time, since the rubber buffer is the main damping element and is easy to replace, when the rubber material is worn or aged due to long-term use, only the rubber buffer needs to be replaced to restore the performance of the coupling, without the need for major repairs or replacement of the entire coupling. Due to the elasticity and deformability of the rubber buffer, this design allows the coupling to adapt to a certain degree of axial and radial deviation.

[0016] Further, the first teeth and the second teeth are evenly distributed on the first shaft sleeve and the second shaft sleeve, respectively.

[0017] The beneficial effects of adopting the above further scheme are:

[0018] The even distribution of the teeth on the first shaft sleeve and the second shaft sleeve makes the connection between the two shaft sleeves more uniform and stable. This design helps to disperse the stress and load generated during transmission, thereby improving the connection strength of the entire coupling. The evenly distributed teeth can ensure that the relative position between the two shaft sleeves remains unchanged during transmission. This helps to reduce vibration and noise caused by the relative movement between the shaft sleeves, thereby improving the stability and reliability of the transmission. The even distribution of the teeth helps to reduce energy loss during transmission. When the two shaft sleeves are engaged with each other through the teeth, the contact area between them is more uniform, thereby reducing the heat and wear caused by friction. This helps to improve the efficiency of the transmission and prolong the service life of the coupling.

[0019] Further, the first teeth and the second teeth are adapted in position and size to the first slot and the second slot of the rubber buffer.

[0020] The beneficial effects of adopting the above further scheme are:

[0021] The first and second clamping teeth are matched with the positions and sizes of the first and second clamping grooves of the rubber buffer, which can ensure the precise connection between them. This precise connection helps to reduce the gap and error in the transmission process, thereby improving the accuracy and stability of the transmission. Through the close fit of the clamping teeth and the clamping grooves, the connection strength of the shaft coupling can be significantly improved. This design helps to prevent the connection from loosening or damaging due to vibration and impact during transmission, thereby prolonging the service life of the shaft coupling. The matching design of the clamping teeth and the clamping grooves makes the installation process of the shaft coupling simpler and faster. During installation, the clamping teeth can be inserted into the corresponding clamping grooves to complete the connection without the need for additional fixing or adjustment steps.

[0022] The utility model provides a kind of shock-absorbing coupling.It has the following beneficial effects:

[0023] Through the design of the rubber buffer, the coupling can effectively absorb and disperse the vibration and impact force generated during transmission. The rubber material itself has good elasticity and damping performance, which can significantly reduce the vibration transmission in the mechanical system and improve the stability and service life of the equipment.

[0024] The structure of the coupling is relatively compact, the first shaft sleeve and the second shaft sleeve are connected by the rubber buffer, and the limiting is realized by the mutual insertion of the clamping teeth and the insertion slot, so that the installation and disassembly process of the whole device becomes simple and fast. In addition, the design of the insertion hole and the fixing hole enables the coupling to be conveniently sleeved on the transmission shaft and locked and fixed by bolts, further simplifying the installation process.

[0025] The rubber buffer not only realizes circumferential limiting by the insertion of the clamping teeth and the insertion slot, but also provides good buffering for the axial movement between the first shaft sleeve and the second shaft sleeve through its wave-shaped undulating cladding design. This design enables the coupling to maintain good stability and durability when subjected to axial force.

[0026] Due to the elasticity and deformability of the rubber buffer, the coupling can adapt to a certain degree of axial and radial deviation, thereby improving the flexibility and reliability of the transmission system. BRIEF DESCRIPTION OF DRAWINGS

[0034] The technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0035] Please refer to Figs. 1-3 The utility model provides the embodiment provided by the utility model:

[0036] Embodiment one

[0037] The utility model provides a kind of shock absorber type coupling, including rubber buffer 2, the both ends of rubber buffer 2 are equipped with first shaft sleeve 1 and second shaft sleeve 3 respectively, first shaft sleeve 1 is equipped with first ratchet tooth 103, second shaft sleeve 3 is equipped with second ratchet tooth 301, first ratchet tooth 103 and second ratchet tooth 301 are evenly distributed on first shaft sleeve 1 and second shaft sleeve 3 respectively, the even distribution design of ratchet tooth on first shaft sleeve 1 and second shaft sleeve 3 makes the connection between two shaft sleeves more uniform and stable. This design strategy helps to disperse the stress and load generated during transmission, thereby improving the connection strength of the entire coupling. The evenly distributed ratchet teeth can ensure that the relative position between the two shaft sleeves remains unchanged during transmission, thereby reducing the vibration and noise caused by the relative movement of the shaft sleeves, improving the stability and reliability of the transmission. In addition, the even distribution of ratchet teeth also helps to reduce energy loss during transmission. When the two shaft sleeves are engaged with each other through the ratchet teeth, the contact area between them is more uniform, thereby reducing the heat and wear caused by friction, improving the efficiency of the transmission, and prolonging the service life of the coupling. First shaft sleeve 1 and second shaft sleeve 3 are respectively provided with insertion slots corresponding to second ratchet tooth 301 and first ratchet tooth 103, first ratchet tooth 103 and second ratchet tooth 301 are adapted to the position and size of first slot 201 and second slot 202 of rubber buffer 2, and first ratchet tooth 103 and second ratchet tooth 301 are accurately adapted to the position and size of first slot 201 and second slot 202 of rubber buffer 2, ensuring accurate connection between them. This precise connection design helps to reduce the gap and error during transmission, thereby improving the accuracy and stability of the transmission. Through the close cooperation of ratchet teeth and slots, the connection strength of the coupling can be significantly improved, preventing the connection from loosening or damaging due to vibration and impact during transmission, thereby prolonging the service life of the coupling. The adaptive design of ratchet teeth and slots also simplifies the installation process of the coupling, making installation more convenient. During installation, the connection can be completed by simply inserting the ratchet teeth into the corresponding slots, without the need for additional fixing or adjustment steps, significantly improving installation efficiency.Meanwhile, since the rubber buffer 2 is the main damping element and is easy to replace, when the rubber material is worn or aged due to long-term use, only the rubber buffer 2 needs to be replaced to restore the performance of the coupling, without the need for overhaul or replacement of the entire coupling. The elasticity and deformability of the rubber buffer 2 enable the coupling to adapt to a certain degree of axial and radial deviation, enhancing its adaptability and flexibility. The first clamping groove 201 and the second clamping groove 202 are provided on the rubber buffer 2, and the rubber buffer 2 is limited by the first clamping tooth 103 and the second clamping tooth 301 through the first clamping groove 201 and the second clamping groove 202. The rubber buffer 2 is in a wave-like state and is wrapped around the first clamping tooth 103 and the second clamping tooth 301. The wave-like design of the rubber buffer 2 enables it to more efficiently absorb and disperse energy when subjected to impact or vibration. This design strategy significantly increases the contact area between the rubber buffer 2 and the clamping tooth, thereby improving the frictional resistance and greatly enhancing the damping efficiency. In addition, the wave-like rubber buffer 2 exhibits excellent adaptability and can well cope with the axial and radial deviation between the transmission shafts. When there is a slight displacement between the transmission shafts, the wave-like design allows the rubber buffer 2 to elastically deform, effectively absorbing the energy generated by these displacements and avoiding excessive impact on the transmission system. Through the wave-like wrapping design, the rubber buffer 2 can closely fit the first clamping tooth 103 and the second clamping tooth 301, significantly enhancing the connection stability between the components of the coupling and effectively preventing relative rotation or loosening of the coupling during transmission, ensuring the stability and reliability of the transmission.

[0038] Embodiment two

[0039] In order to facilitate the installation of the first shaft sleeve 1 and the second shaft sleeve 3 on the transmission shaft, as shown in Figs. 1-3 the application further comprises: a plug-in hole 101 is provided on the first shaft sleeve 1 and the second shaft sleeve 3, a fixing hole 102 is provided on one side of the plug-in hole 101, a bolt is installed in the fixing hole 102, and the first shaft sleeve 1 and the second shaft sleeve 3 are sleeved on one end of the transmission shaft through the plug-in hole 101 and locked and fixed by the bolt in the fixing hole 102.

[0040] Working principle:

[0041] When the two transmission shafts are connected by the coupling, the first shaft sleeve 1 and the second shaft sleeve 3 are respectively sleeved on one end of the two transmission shafts and locked and fixed by the bolts in the plug-in hole 101 and the fixing hole 102. During transmission, the torque is transmitted to the other transmission shaft through the first shaft sleeve 1 and the second shaft sleeve 3 and the rubber buffer 2 therebetween.

[0042] The rubber buffer 2 is the core component of the coupling, which has good elasticity and damping performance. When the transmission system is subjected to vibration or impact force, the rubber buffer 2 can absorb and disperse these energies, thereby reducing the influence of vibration and impact on the transmission system. The wavy design of the rubber buffer 2 further enhances its shock-absorbing and buffering capacity, so that the coupling can better adapt to the axial and radial deviations.

[0043] The first shaft sleeve 1 and the second shaft sleeve 3 are respectively provided with first clamping teeth 103 and second clamping teeth 301, which are uniformly distributed on the shaft sleeve. The rubber buffer 2 is provided with first clamping grooves 201 and second clamping grooves 202 corresponding to the first clamping teeth 103 and the second clamping teeth 301. When the coupling is installed in place, the first clamping teeth 103 and the second clamping teeth 301 are respectively inserted into the first clamping grooves 201 and the second clamping grooves 202, realizing the circumferential limiting action. This design prevents the relative rotation of the coupling during transmission, ensuring the stability of the transmission.

[0044] Due to the elasticity and deformability of the rubber buffer 2, it can adapt to the axial deviation between the transmission shafts to a certain extent. When there is a slight axial displacement between the transmission shafts, the rubber buffer 2 can be elastically deformed, thereby absorbing and dispersing the energy generated by the displacement, avoiding excessive impact on the transmission system.
