Description

Technical Field

[0001] The utility model relates to the technical field of couplings, in particular to a connecting sleeve with high torque and high speed. Background Art

[0002] Couplings are commonly used components in mechanical transmission. They are used to connect two shafts in different mechanisms so that they rotate together to transmit torque. They can compensate for the relative displacement between the two shafts to a certain extent, including axial, radial, and angular displacement, thereby effectively reducing the impact of shaft installation errors or deformation during operation on the transmission system. There are many types of couplings, including rigid couplings and flexible couplings. Rigid couplings have a simple structure and transmit large torque, but have high requirements for the concentricity of the two shafts. Flexible couplings can better adapt to the relative displacement of the two shafts, protect equipment, and are widely used in the transmission systems of various mechanical equipment.

[0003] However, the existing connecting sleeve and the base are fixed by bolts, which makes it inconvenient to perform maintenance and replacement after long-term use, thereby increasing the maintenance burden of the equipment and shortening the service life of the equipment. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that the existing connecting sleeve and the base are fixed by bolts, which is inconvenient to maintain and replace after long-term use, increases the maintenance burden of the equipment, and causes a short service life of the equipment. A connecting sleeve with high torque and high speed is proposed.

[0005] The transmission mechanism is that the cam is fixed with the drive shaft and the transmission mechanism is fixed with the drive shaft through the cam, and the transmission mechanism is fixed with the drive shaft through the cam.

[0006] Preferably, there are two moving rods, and the two moving rods are arranged in a mirror-symmetrical manner. By arranging the moving rods, it is convenient to cooperate with the fixing ring for movement, and the fixing ring is guided and supported, thereby increasing the safety of the equipment.

[0007] Preferably, the clamping block and the fixing ring are symmetrically arranged, and the fixing ring and the clamping block are in contact with the connecting rod. By setting the fixing ring, when the connecting sleeve needs to be replaced, the fixing ring is pulled, and the fixing ring drives the rod body to separate from the connecting rod, thereby pulling the connecting sleeve from the base. When the connecting sleeve is reset, the pressure spring is released, and the pressure spring generates elastic force to squeeze the fixing ring, and the fixing ring drives the rod body to be inserted into the connecting rod, thereby fixing the connecting sleeve and ensuring the stability of the entire device under normal working conditions.

[0008] Preferably, a pressure spring is fixedly connected to one side of the fixing ring, and the side of the pressure spring away from the fixing ring is fixedly connected to the clamping block. By providing the pressure spring, when the coupling sleeve is reset, the pressure spring is released and uses its own elastic force to squeeze the fixing ring, driving the rod body to insert into the connecting rod, thereby achieving the fixation of the coupling sleeve, ensuring the stability of the coupling during operation and ensuring that it can normally transmit high torque. This fixing method using spring elastic force is convenient to operate and helps to improve work efficiency. At the same time, when replacement or other operations are required, this fixed state can be released by pulling the fixing ring or other operations.

[0009] Preferably, a protective device is provided on the surface of the oil filling hole, and the protective device includes a rubber pad, which is fixedly connected to the connecting sleeve, and a plug rod is fixedly connected to the surface of the rubber pad. A sealing plug is inserted into the surface of the oil filling hole. By providing the protective device, the oil filling hole is closed when not in use, reducing dust clogging the oil filling hole, thereby ensuring the normal operation of the entire coupling, reducing the occurrence of faults, and improving the use efficiency and life.

[0010] Preferably, a pressure block is fixedly connected to the surface of the sealing plug, and a circular hole is opened on the surface of the pressure block. By setting the sealing plug, the function of the sealing plug is to prevent dust from clogging the oil filling hole when not in use. When the sealing plug is inserted into the oil filling hole by pressing the pressure block, the insertion rod is inserted into the circular hole, and the pressure block is against the rubber pad, the oil filling hole can be effectively sealed and protected to ensure the cleanliness of the oil filling hole and ensure that when the coupling needs to be oiled, the oiling process can proceed smoothly without being disturbed by impurities such as dust.

[0011] Preferably, the insertion rod is inserted into the circular hole, and there are two insertion rods, which are arranged in a mirror-symmetrical manner. By setting the insertion rod, the function of the insertion rod is to cooperate with the circular hole when the oil filling hole is sealed and protected by the sealing plug, and the auxiliary pressure block is against the rubber pad, so as to better complete the sealing protection of the oil filling hole, prevent dust from clogging the oil filling hole, and ensure that the oil filling hole is in a well-closed state when not in use.

[0012] Compared with the prior art, the advantages and positive effects of the present invention are:

[0013] In the utility model, by setting a combination device and a protective device, the original coupling has high requirements on the precision of the inner cone and the surface roughness is also quite high. If the surface contact is not good, oil will leak when pressurized, and high pressure cannot be added, so that the coupling cannot expand. After the improvement, the coupling is tightly connected to the shaft by making the coupling fit with the shaft, so that the hydraulic oil can be stored in the hydraulic tank, and the coupling can be heated. Through experiments, it is found that as long as the coupling is heated to 200 degrees, the inner hole of the coupling will expand by 0.05mm-0.08mm, and the pressure oil is injected into the coupling from the oil filling port through the manual high-pressure oil pump. The coupling is pressurized to expand, and a thrust is continuously added to the coupling through the hydraulic specific tooling. When the coupling reaches the position specified by the shaft, the manual hydraulic pump is unloaded, so that a large torque can be transmitted, which greatly reduces The processing and assembly difficulty are reduced, and the work efficiency is improved. When in use, the fixing ring is pulled to drive the rod body to separate from the connecting rod. At this time, the connecting sleeve can be pulled out of the base for easy replacement. When the connecting sleeve is reset, the pressure spring is loosened, and the pressure spring loses its restraint and generates elastic force to squeeze the fixing ring to drive the rod body to be inserted into the connecting rod. At this time, the connecting sleeve is fixed. In order to reduce dust clogging the oil filling hole, the oil filling hole is closed by a sealing plug when not in use. The sealing plug is driven by pressing the pressure block to insert the oil filling hole, and the rod is inserted into the round hole. The pressure block and the rubber pad are against each other to complete the protection. By setting up the utility model, during the operation of the equipment, if the connecting sleeve fails, the fixing ring can be quickly pulled to separate the rod body from the connecting rod, and the connecting sleeve can be pulled out of the base for replacement. There is no need for complicated disassembly process, and the normal operation of the equipment can be restored in time, reducing downtime. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] See also Figure 1-5 The utility model provides a technical solution: a high-torque and high-speed connecting sleeve, including a base 1 and a combination device 5, a transmission shaft 2 is installed on the surface of the base 1, a connecting sleeve 3 is provided on the surface of the transmission shaft 2, an oil filling hole 4 is opened on one side of the connecting sleeve 3, and the combination device 5 is arranged on one side of the base 1.

[0021] The specific configuration and function of the combined device 5 and the protective device 6 will be described in detail below.

[0022] In this embodiment: the combination device 5 includes a connecting rod 52, which is fixedly connected to the base 1, and a block 51 is fixedly connected to one side of the connecting sleeve 3. A groove 1 is provided on the surface of the block 51, and a moving rod 53 is slidably connected to the inner wall of the groove 1 on the surface of the block 51. A fixing ring 54 is fixedly connected to one side of the moving rod 53, and a rod body 56 is fixedly connected to one side of the fixing ring 54. A hole 1 is provided on the surface of the connecting rod 52, and the rod body 56 is inserted into the hole 1 on the surface of the connecting rod 52. By setting the combination device 5, during the operation of the equipment, if the connecting sleeve 3 fails, the fixing ring 54 can be quickly pulled to disengage the rod body 56 from the connecting rod 52, and the connecting sleeve 3 can be pulled out of the base 1 for replacement. There is no need for a complicated disassembly process, and the normal operation of the equipment can be restored in time, reducing downtime.

[0023] Specifically, there are two moving rods 53, and the two moving rods 53 are arranged in mirror symmetry. By providing the moving rods 53, it is convenient to cooperate with the fixing ring 54 to move, guide and support the fixing ring 54, and increase the safety of the equipment.

[0024] Specifically, the block 51 and the fixing ring 54 are symmetrically arranged, and the fixing ring 54 and the block 51 are in contact with the connecting rod 52. By setting the fixing ring 54, when the connecting sleeve 3 needs to be replaced, the fixing ring 54 is pulled, and the fixing ring 54 drives the rod body 56 to separate from the connecting rod 52, thereby pulling the connecting sleeve 3 from the base 1. When the connecting sleeve 3 is reset, the pressure spring 55 is released, and the pressure spring 55 generates elastic force to squeeze the fixing ring 54, and the fixing ring 54 drives the rod body 56 to be inserted into the connecting rod 52, thereby fixing the connecting sleeve 3 and ensuring the stability of the entire device under normal working conditions.

[0025] Specifically, a pressure spring 55 is fixedly connected to one side of the fixing ring 54. The side of the pressure spring 55 away from the fixing ring 54 is fixedly connected to the clamping block 51. By providing the pressure spring 55, when the coupling sleeve 3 is reset, the pressure spring 55 is released and uses its own elastic force to squeeze the fixing ring 54, driving the rod body 56 to insert into the connecting rod 52, thereby securing the coupling sleeve 3, ensuring the stability of the coupling during operation and ensuring that it can normally transmit high torque. This fixing method using spring elastic force is convenient to operate and helps improve work efficiency. At the same time, when replacement or other operations are required, this fixed state can be released by pulling the fixing ring 54.

[0026] Specifically, a protective device 6 is provided on the surface of the oil filling hole 4. The protective device 6 includes a rubber pad 63. The rubber pad 63 is fixedly connected to the connecting sleeve 3. An insertion rod 62 is fixedly connected to the surface of the rubber pad 63. A sealing plug 65 is inserted into the surface of the oil filling hole 4.

[0027] In this embodiment, by providing a protective device 6, the oil filling hole 4 is closed when not in use, reducing dust from clogging the oil filling hole 4, thereby ensuring the normal operation of the entire coupling, reducing the occurrence of faults, and improving the efficiency and life of the coupling.

[0028] Specifically, a pressing block 61 is fixedly connected to the surface of the sealing plug 65 , and a circular hole 64 is opened on the surface of the pressing block 61 .

[0029] In this embodiment, a sealing plug 65 is provided to prevent dust from clogging the oil filling hole 4 when not in use. When the sealing plug 65 is inserted into the oil filling hole 4 by pressing the pressure block 61, the insertion rod 62 is inserted into the circular hole 64, and the pressure block 61 abuts against the rubber pad 63, the oil filling hole 4 can be effectively sealed and protected, ensuring the cleanliness of the oil filling hole 4 and ensuring that when the coupling needs to be oiled, the oiling process can proceed smoothly without being disturbed by impurities such as dust.

[0030] Specifically, the insertion rod 62 is inserted into the circular hole 64 , and there are two insertion rods 62 , which are arranged in a mirror-symmetrical manner.

[0031] In this embodiment, an insertion rod 62 is provided. The function of the insertion rod 62 is to cooperate with the circular hole 64 when the oil filling hole 4 is sealed and protected by the sealing plug 65, and the auxiliary pressure block 61 is against the rubber pad 63, so as to better complete the sealing protection of the oil filling hole 4, prevent dust from clogging the oil filling hole 4, and ensure that the oil filling hole 4 is in a well-sealed state when not in use.

[0032] Working principle: By setting the combination device 5 and the protective device 6, the original coupling has high requirements for the precision of the inner cone and the surface roughness is also quite high. If the surface contact is not good, oil will leak when pressurized, and high pressure cannot be applied, so the coupling cannot expand. After the improvement, the coupling is tightly connected to the shaft by making the coupling fit with the shaft, so that the hydraulic oil can be stored in the hydraulic tank, and the coupling can be heated. Through the test, as long as the coupling is heated to 200 degrees, the inner hole of the coupling will expand by 0.05mm-0.08mm, and the pressure oil is injected into the coupling from the oil filling port through the manual high-pressure oil pump. The coupling is pressurized to expand, and a thrust is continuously added to the coupling through the hydraulic specific tooling. When the coupling reaches the specified position of the shaft, the manual hydraulic pump is unloaded, so that a large torque can be transmitted, which greatly reduces the difficulty of processing and assembly and improves work efficiency. When in use, When the connecting sleeve 3 is reset, the pressure spring 55 is released, and the pressure spring 55 loses its restraint and generates elastic force to squeeze the fixing ring 54 to drive the rod body 56 to be inserted into the connecting rod 52. At this time, the connecting sleeve 3 is fixed. In order to reduce the clogging of the oil filling hole 4 by dust, the oil filling hole 4 is closed by the sealing plug 65 when not in use. The sealing plug 65 is driven by pressing the pressure block 61 to insert the oil filling hole 4, and the insertion rod 62 is inserted into the circular hole 64. The pressure block 61 and the rubber pad 63 are against each other to complete the protection. By setting up the utility model, during the operation of the equipment, if the connecting sleeve 3 fails, the fixing ring 54 can be quickly pulled to separate the rod body 56 from the connecting rod 52, and the connecting sleeve 3 can be pulled out of the base 1 for replacement. There is no need for a complicated disassembly process, and the normal operation of the equipment can be restored in time, reducing downtime.
