Description

Technical Field

[0001] This utility model relates to the field of rubber connecting shaft technology, specifically a rubber connecting shaft. Background Technology

[0002] In mechanical transmission systems, couplings are essential components. Their function is to connect two shafts and make them rotate together to transmit torque. Traditional couplings (such as rigid couplings) can transmit torque efficiently, but they lack buffering and shock absorption capabilities. When the equipment starts up, stops, or experiences sudden load changes, they will generate significant impacts and vibrations. This will not only reduce the service life of the equipment, but also affect the operating accuracy and stability of the equipment.

[0003] However, existing technologies still have significant shortcomings, such as:

[0004] In the existing technology, although rubber couplings have certain buffering and shock absorption performance, their ability to compensate for torque between shafts is limited during long-term use, making it difficult to adapt to the relative displacement changes between the two shafts under complex working conditions. Utility Model Content

[0005] The purpose of this invention is to provide a rubber connecting shaft to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a rubber connecting shaft, including a first connector and a second connector disposed at one end thereof, wherein a rubber elastic component for reducing vibration transmission is installed between the first connector and the second connector;

[0007] The rubber elastic component includes a rubber block installed between the first connector and the second connector. The surface of the rubber block is provided with a plurality of mounting grooves, and two connecting protrusions adapted to the mounting grooves are provided on the side adjacent to the first connector and the second connector. The mounting grooves and the connecting protrusions are slidably connected to reduce the vibration transmission between the first connector and the second connector.

[0008] Preferably, the rubber block has several mounting cavities inside, and each of the mounting cavities has a rubber elastic column fixedly installed inside it;

[0009] The interior of the rubber elastic column is provided with several honeycomb-shaped rubber components, and the honeycomb-shaped rubber components are arranged in a ring at equal intervals inside the rubber elastic column.

[0010] Preferably, the rubber block has several slots on both sides, and a card block is fixedly installed on the side adjacent to the first connector and the second connector, and the card block and the slot are connected by insertion.

[0011] Preferably, the rubber block has connecting holes fixedly installed on both sides and on one side of the slot, and a connecting post is provided between the first connector and the second connector and on one side of the block, and the connecting holes and the connecting post are snap-fitted together.

[0012] Preferably, the locking block and the connecting protrusion are both fixed to one side of the first connector and the second connector, and the locking block and the connecting protrusion are arranged in a ring at equal distances.

[0013] Preferably, a countersunk hole is provided on one side of the surface of both the first connector and the second connector, and a bolt is installed through the interior of both countersunk holes.

[0014] Preferably, the first connector and the second connector are connected by die-casting of a rubber elastic component, so as to form a whole between the first connector, the second connector and the rubber elastic component.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By utilizing the rubber elastic component, the rubber block inside the rubber elastic component has good elasticity. During the transmission of torque, it can effectively absorb and buffer the vibration and impact generated during the operation of the equipment, so as to reduce damage to the equipment, reduce noise, and improve the operational stability of the equipment. Furthermore, the connecting protrusion and the mounting groove are staggered, and the rubber block can undergo a certain degree of elastic deformation when subjected to force, thereby compensating for the axial, radial and angular displacement between the two shafts to adapt to the installation error of the equipment and the change of the shaft position during operation.

[0017] 2. By utilizing the rubber elastic pillars and honeycomb rubber components, the rubber elastic pillars can provide support inside the mounting cavity when the rubber block is under stress. When the rubber block is subjected to excessive stress, the honeycomb rubber components inside the rubber elastic pillars can effectively resist torsional forces. Furthermore, the resilience of the honeycomb rubber components can restore the rubber block to its initial state, thereby improving the deformation capacity of the rubber block and preventing the rubber block from being unable to recover after elastic deformation under stress, which could affect the normal use of the first and second connectors.

[0023] 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.

[0024] Please see Figures 1-4 The present invention provides a technical solution: a rubber connecting shaft, including a first connecting head 1 and a second connecting head 2 disposed at one end thereto, wherein a rubber elastic component 3 for reducing vibration transmission is installed between the first connecting head 1 and the second connecting head 2.

[0025] The rubber elastic component 3 includes a rubber block 31 installed between the first connector 1 and the second connector 2. The surface of the rubber block 31 is provided with a plurality of mounting grooves 32, and two connecting protrusions 33 adapted to the mounting grooves 32 are provided on the side adjacent to the first connector 1 and the second connector 2. The mounting grooves 32 and the connecting protrusions 33 are slidably connected to reduce the vibration transmission between the first connector 1 and the second connector 2.

[0026] In this embodiment, during the transmission of torque, the vibration and impact generated during equipment operation can be effectively absorbed and buffered to reduce damage to the equipment. Furthermore, the connecting protrusion 33 and the mounting groove 32 are staggered, and the rubber block 31 can undergo a certain degree of elastic deformation when subjected to force to compensate for the axial, radial and angular displacement between the two shafts, so as to adapt to the installation error of the equipment and the change of the shaft position during operation.

[0027] Reference Figure 3 as well as Figure 4 As shown, the rubber block 31 has several mounting cavities 34 inside, and a rubber elastic column 35 is fixedly installed inside each of the mounting cavities 34; a number of honeycomb rubber parts 36 are arranged inside the rubber elastic column 35, and the honeycomb rubber parts 36 are arranged in a ring at equal intervals inside the rubber elastic column 35.

[0028] In this embodiment, when the rubber block 31 is subjected to force, the rubber elastic column 35 provides support inside the mounting cavity 34. When the rubber block 31 is subjected to excessive force, the honeycomb rubber component 36 inside the rubber elastic column 35 can effectively resist the torsional force. Furthermore, by utilizing the resilience of the honeycomb rubber component 36, the rubber block 31 can be restored to its initial state, thereby improving the deformation capability of the rubber block 31 and preventing the rubber block 31 from being difficult to recover when it undergoes elastic deformation under force, which would affect the normal use of the first connector 1 and the second connector 2.

[0029] Reference Figure 1 as well as Figure 2 As shown, several slots 37 are provided on both sides of the rubber block 31, and a locking block 38 is fixedly installed on the side adjacent to the first connector 1 and the second connector 2, with the locking block 38 and the slot 37 being inserted into each other; connecting holes 310 are fixedly installed on both sides of the rubber block 31 and on the side of the slot 37, and a connecting post 39 is provided between the first connector 1 and the second connector 2 and on the side of the locking block 38, with the connecting hole 310 and the connecting post 39 being snapped together; the locking block 38 and the connecting protrusion 33 are both fixed on one side of the first connector 1 and the second connector 2, and the locking block 38 and the connecting protrusion 33 are arranged in a ring at equal distances.

[0030] In this embodiment, during the transmission process between the first connector 1 and the second connector 2, the axial, radial, and angular displacements between the rubber block 31 and the first connector 1 and the second connector 2 can be further compensated to adapt to equipment installation errors and changes in shaft position during operation.

[0031] Reference Figure 1 as well as Figure 2 As shown, countersunk holes 4 are provided on one side of the surface of the first connector 1 and the second connector 2, and bolts 5 are installed through the interior of both countersunk holes 4.

[0032] In this embodiment, the two half-couplings can be tightly connected together to form a whole, ensuring that power can be transmitted from the driving shaft to the driven shaft through the coupling.

[0033] Reference Figure 1 As shown, the first connector 1 and the second connector 2 are connected by a rubber elastic component 3 through die casting, so as to form a whole between the first connector 1, the second connector 2 and the rubber elastic component 3;

[0034] In this embodiment, it can be integrated with the coupling to avoid gaps and delays in the coupling during transmission, thus ensuring the positioning accuracy of the coupling.

[0035] Working principle: The rubber block 31 inside the rubber elastic component 3 has good elasticity. During the transmission of torque, it can effectively absorb and buffer the vibration and impact generated during equipment operation to reduce damage to the equipment. The connecting protrusion 33 and the mounting groove 32 are staggered. When the rubber block 31 is under force, it can undergo a certain degree of elastic deformation to compensate for the axial, radial and angular displacement between the two shafts to adapt to the installation error and the change of shaft position during operation. When the rubber block 31 is under force, the rubber elastic column 35 provides support inside the mounting cavity 34. When the rubber block 31 is under excessive force, the honeycomb rubber component 36 inside the rubber elastic column 35 can effectively resist the torsional force. The resilience of the honeycomb rubber component 36 can restore the rubber block 31 to its initial state to improve the deformation capacity of the rubber block 31.
