Description

Technical Field

[0001] The invention complies with the technical field of reducers, and in particular relates to a self-cooling reducer for transmission. Background Art

[0002] A reducer is a mechanical transmission device whose main function is to reduce speed and increase torque. It achieves speed conversion between the input shaft and the output shaft through a gear set or other forms of transmission components (such as worm gears, planetary gears, etc.). In industrial applications, reducers are very common and are widely used in various mechanical equipment and systems, such as conveyor belts, cranes, mixers, and automated production lines. The function of a reducer is not limited to reducing speed and increasing torque, but also includes matching load requirements, isolating vibrations, and changing the direction of movement. Reducers can be divided into many types according to different application scenarios and technical requirements. Common classification methods include transmission type (such as gear reducers, worm gear reducers), structural forms (such as cylindrical gear reducers, bevel gear reducers), and specific uses (such as special reducers). Therefore, choosing the right reducer is crucial to ensuring equipment performance and efficiency.

[0003] Existing gear reducers and worm gear reducers mostly use two housings combined to isolate the transmission components from the outside world. Lubricating oil is injected between the two housings to reduce the friction between the transmission components and reduce the heat generated by friction. However, the two housings of the existing reducer are generally connected with a number of bolts. When this connection method is selected, the bolts need to be tightened one by one, which is time-consuming and labor-intensive. Summary of the invention

[0009] In addition, it is particularly preferred that it further includes: a second fixed shell, fixedly connected to the first outer shell, and all the first sliding grooves are connected to the second fixed shell; and a sliding plate, slidably connected in the second fixed shell.

[0010] In addition, it is particularly preferred that the method further comprises: a threaded rod threadedly connected to the second fixed shell, and the threaded rod is rotatably connected to the sliding plate.

[0011] In addition, it is particularly preferred that the method further comprises: two seals, both of which are arranged between the first housing and the second housing, the input shaft and the output shaft are respectively located in adjacent seals, and the seals are provided with cavities.

[0012] In addition, it is particularly preferred that the cross section of the sealing member is in a herringbone shape and is made of an elastic material so that the sealing member is tightly attached to the input shaft or the output shaft when under pressure.

[0015] Compared with the prior art, the present invention has the following advantages: the present invention realizes quick connection between the first shell and the second shell by passing the connecting pin through the adjacent through holes on the second shell and limiting the connecting pin by using a limiting member, thereby improving the efficiency of the device during installation and disassembly, reducing the time used, and realizing heat dissipation of the device by arranging a plurality of fins on the outer sides of the first shell and the second shell.

[0017] When the input shaft or output shaft vibrates, the input shaft or output shaft drives the adjacent sliding member to move, thereby pressurizing the seal to prevent the input shaft or output shaft from vibrating and causing a gap between the adjacent seal and thereby avoiding lubricating oil leakage.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0021] A self-cooling reducer for transmission, such as Figure 1 and Figure 2As shown, it includes: a first housing 1, a second housing 2 is arranged on one side of the first housing 1, a plurality of fins are arranged on the outer sides of the first housing 1 and the second housing 2, an input shaft 3 and an output shaft 4 are arranged between the first housing 1 and the second housing 2, and a transmission assembly is arranged between the input shaft 3 and the output shaft 4; a plurality of connecting pins 5, the first housing 1 is provided with the same number of first slide grooves 101 as the connecting pins 5, the connecting pins 5 are slidably connected to the adjacent first slide grooves 101, the second housing 2 is provided with the same number of through holes as the connecting pins 5, the connecting pins 5 pass through the adjacent through holes on the second housing 2; a limiting member 6, the number of which is the same as the number of the connecting pins 5, the connecting pins 5 are provided with second slide grooves 501, the limiting member 6 is slidably connected to the adjacent second slide grooves 501. The limiting member 6 is provided with an inclined surface on the side away from the first housing 1, which is used to increase the speed of the connecting pin 5 passing through the adjacent through holes on the second housing 2.

[0022] In the above scheme, it is intended to achieve a quick connection between the first shell 1 and the second shell 2. All fins on the outside of the first shell 1 and the outside of the second shell 2 are used to increase the contact area between the device and the air, so as to achieve heat dissipation of the device. The fins are made of materials with good thermal conductivity, such as copper and aluminum, to further improve the heat dissipation effect of the device. The transmission component can be a gear set or a threaded screw, etc. The connecting pin 5 is made of materials with good tensile properties, such as steel. The connecting pin 5 and the first slide groove 101 are sealed and slidable, and the limiter 6 and the second slide groove 501 are sealed and slidable. The limiter 6 includes a limit part and a transmission part. The limit part of the limiter 6 is a wedge block, and the transmission part of the limiter 6 is a cylinder. The inclined surface on the limiter 6 is located at its limit part. When the connecting pin 5 passes through the adjacent through hole on the second shell 2, the through hole squeezes the inclined surface on the limiter 6, so that the limiter 6 is retracted into the connecting pin 5, so that the connecting pin 5 is quickly inserted into the through hole on the second shell 2.

[0023] Further, such as Figure 1 and Figure 3 As shown, it also includes: a first fixed shell 7, fixed to the first outer shell 1, and all second slide grooves 501 are connected to the first fixed shell 7; an adjusting member 8, slidably connected to the first fixed shell 7, and a first spring is arranged between the adjusting member 8 and the first fixed shell 7.

[0024] In the above scheme, the purpose is to simultaneously control the movement of all the limit members 6. The adjusting member 8 is sealed with the first fixed shell 7, and the second slide groove 501 and the first fixed shell 7 are filled with liquid for transmission, so that when the adjusting member 8 moves, all the limit members 6 are simultaneously driven to move.

[0025] Further, such as Figure 3As shown, it also includes: a limiting column 9, which is slidably connected to the adjusting member 8, a second spring is arranged between the limiting column 9 and the adjusting member 8, and the first fixed shell 7 is provided with two grooves, which are used to limit the limiting column 9.

[0026] In the above scheme, the position of the adjusting member 8 is maintained so that the connecting pin 5 can be separated from the through hole on the second housing 2. The limiting column 9 is composed of a hemisphere and a cylinder, and the second spring between the limiting column 9 and the adjusting member 8 is initially in a compressed state, which is used to provide the limiting column 9 with the force required to limit the adjusting member 8.

[0027] Further, such as Figure 1 and Figure 2 As shown, it also includes: a second fixed shell 10 fixedly connected to the first shell 1, all the first slide grooves 101 are connected to the second fixed shell 10; and a sliding plate 11 slidably connected in the second fixed shell 10.

[0028] In the above scheme, the purpose is to simultaneously drive all the connecting pins 5 to move and pressurize all the limit members 6 to ensure the connection strength between the first housing 1 and the second housing 2. The sliding plate 11 and the second fixed housing 10 are sealed, and the first slide groove 101 and the second fixed housing 10 are both filled with liquid for transmission, which can be hydraulic oil or water.

[0029] Further, such as Figure 1 and Figure 2 As shown, it also includes: a threaded rod 12, which is threadedly connected to the second fixed shell 10, and the threaded rod 12 is rotatably connected to the sliding plate 11.

[0030] In the above scheme, the position of the sliding plate 11 is adjusted. The threaded rod 12 can be provided with an inner hexagon and an outer hexagon to facilitate the rotation of the threaded rod 12. When the threaded rod 12 rotates, it will move up and down to drive the sliding plate 11 to move up and down.

[0031] Workflow: When assembling the device, first connect the transmission component (such as a gear or a worm gear) and the input shaft 3 and the output shaft 4 and place them in the second housing 2, then align the first housing 1 and the second housing 2, and move the first housing 1 downward. The first housing 1 drives all the connecting pins 5 to move downward, and the connecting pins 5 drive the limiter 6 to move. The lower side of the connecting pin 5 is inserted into the through hole on the second housing 2. When the limiter 6 contacts the through hole on the second housing 2, the limiter 6 is squeezed and moves into the connecting pin 5. When the limiter 6 moves, the liquid in the second slide groove 501 is pressed into the first fixed shell 7. The liquid in the first fixed shell 7 increases, pushing the adjusting member 8 to move downward and compressing the first spring adjacent to it. When the adjusting member 8 moves downward, it drives the limiter column 9 to move. The limiter column 9 is squeezed and moves into the adjusting member 8 and compresses the adjacent second spring.

[0032] When the limit member 6 passes through the through hole on the second shell 2, the limit member 6 loses the extrusion of the second shell 2, and the adjusting member 8 is reset under the action of the first spring adjacent to it. When the adjusting member 8 is reset, the transmission limit member 6 is reset, thereby jamming the connecting pin 5 to achieve a quick connection between the first shell 1 and the second shell 2. Then, the threaded rod 12 is rotated, and the threaded rod 12 drives the sliding plate 11 to move downward. When the sliding plate 11 moves downward, all the liquid in the first slide groove 101 is drawn into the second fixed shell 10, so that the connecting pin 5 drives the limit member 6 to move upward, and pressurizes the space between the limit member 6 and the second shell 2 to ensure the connection strength between the first shell 1 and the second shell 2.

[0033] Further, such as Figure 4 and Figure 6 As shown, it also includes: two seals 13, both of which are arranged between the first housing 1 and the second housing 2, the input shaft 3 and the output shaft 4 are respectively located in adjacent seals 13, and the seals 13 are provided with cavities. The seals 13 are in a herringbone shape and are made of elastic material, so that the seals 13 are tightly attached to the input shaft 3 or the output shaft 4 when under pressure.

[0034] In the above scheme, the purpose is to prevent the leakage of lubricating oil in the first housing 1 and the second housing 2. The cross section of the seal 13 is herringbone, and the inner side of the seal 13 is in contact with the input shaft 3 or the output shaft 4. When the pressure on the outer side of the seal 13 increases, the seal 13 deforms inwardly, thereby increasing the contact area between the seal 13 and the input shaft 3 or the output shaft 4, so as to improve the sealing performance between the two.

[0035] Further, such as Figure 1 , Figure 4 , Figure 5 and Figure 7 As shown, it also includes: a mounting frame 14, having two, both of which are fixed to the second housing 2, the two mounting frames 14 are respectively sleeved on the outer side of the input shaft 3 and the outer side of the output shaft 4, and the mounting frame 14 is provided with third sliding grooves 1401 distributed at equal intervals in the circumferential direction; sliding members 15, the number of which is consistent with the number of the third sliding grooves 1401, the sliding members 15 are slidably connected to adjacent third sliding grooves 1401, and the third sliding grooves 1401 distributed at equal intervals in the circumferential direction are connected to each other, and one of the third sliding grooves 1401 is connected to the cavity of the sealing member 13.

[0036] Further, such as Figure 5 As shown, the invention also includes: rollers 16 , the number of which is the same as the number of the sliding members 15 , and the rollers 16 are rotatably connected to the adjacent sliding members 15 .

[0037] In the above scheme, it is intended to ensure the sealing between the input shaft 3 and the output shaft 4 and the first housing 1 and the second housing 2 when vibrating. The sliding member 15 and the third sliding groove 1401 are sealed, and the cavities of the third sliding groove 1401 and the sealing member 13 are filled with liquid for transmission, such as hydraulic oil and water. A gap is provided between the roller 16 and the input shaft 3 or the output shaft 4 to prevent the roller 16 from rotating when the input shaft 3 or the output shaft 4 rotates normally, thereby reducing wear. A blocking ring is provided in the third sliding groove 1401, and when the input shaft 3 or the output shaft 4 vibrates, one or several rollers 16 are squeezed, and the roller 16 drives the sliding member 15 to move, preventing the remaining sliding members 15 that are not squeezed from moving in the direction close to the input shaft 3 or the output shaft 4, so as to prevent the liquid in the third sliding groove 1401 from being unable to pressurize the sealing member 13.

[0038] Working process: When the input shaft 3 or the output shaft 4 vibrates, taking the vibration of the output shaft 4 as an example, the first shell 1 and the second shell 2 support the output shaft 4. The farther the extended part of the output shaft 4 is from the first shell 1 and the second shell 2, the greater the swing amplitude. The output shaft 4 squeezes the roller 16, and the roller 16 drives the sliding member 15 to move. The sliding member 15 presses the liquid in the third sliding groove 1401 into the cavity of the seal 13, increasing the pressure between the seal 13 and the first shell 1 and the second shell 2, so as to avoid a gap between the output shaft 4 and the seal 13 when the output shaft 4 swings.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to the embodiments without departing from the principles and spirit of the invention.
