Description

Technical Field

[0001] The invention relates to the technical field of transmission devices, and in particular to a chain transmission device with a self-lubricating function. Background Art

[0002] A chain drive is a mechanical power transmission system that uses a chain to transfer power from one place to another. A traditional chain drive consists mainly of two or more sprockets and the chain itself. The holes on the chain links are mounted on the sprocket teeth. When the prime mover rotates, the chain wrapped around the shaft sprocket also rotates, thereby applying mechanical force to the driven shaft to achieve power transmission.

[0003] Chinese patent CN102410347B discloses a "chain transmission device" having a guide roller supported in a manner that can rotate coaxially with the pin of the chain. When the guide roller is wound on the track of the guide rail set along the side of the teeth of the sprocket, the root of the sprocket does not contact the pin, the sleeve or the roller. In this way, the impact and percussion sound caused by the contact when the chain and the sprocket are engaged are reduced, and even if the drive is carried out at a high load and high speed, the impact and percussion sound will not be increased, thereby reducing the vibration, breakage, friction loss, etc. of the chain and sprocket, and improving durability.

[0004] However, the prior art has the following problems:

[0005] When the existing chain transmission device is used on large machinery, the chain transmission device will be subject to greater wear during the use of the large machinery. Therefore, the staff is required to apply lubricant to the chain regularly. Conventional lubricants usually use grease or dry chain oil. When grease is applied to the chain, it will cause the grease to adhere to a large amount of dust in the air, causing the dust to clump, requiring staff to clean it regularly. The cleaning process is relatively troublesome. Dry chain oil can greatly reduce dust adhesion, but due to the poor adhesion of dry chain oil, staff are required to increase the frequency of spraying and the service life is short.

[0038] A lubrication assembly 5 is used for spraying dry chain oil on the chain assembly 4. The lubrication assembly 5 is arranged on the mounting seat 1. The lubrication assembly 5 includes a material box 51. The material box 51 is mounted on the mounting seat 1. A feeding port 52 is arranged on the material box 51. The material box 51 is filled with dry chain oil. The staff can add dry chain oil through the feeding port 52. A mounting plate 53 is mounted on the mounting seat 1. Two cylinders 54 are mounted at the bottom of the mounting plate 53. The inner wall of the cylinder 54 is slidably connected with a piston 55. The bottoms of the two pistons 55 are connected with arc blocks 56. Springs are respectively arranged between the arc blocks 56 and the two cylinders 54. The plurality of sleeves 42 are in contact with the arc blocks 56 during movement. When the sleeves 4 2 contacts the arc block 56, the outer wall of the sleeve 42 contacts the arc surface of the arc block 56, so that the sleeve 42 squeezes the arc block 56 upward when moving, and the arc block 56 is reset by the elastic force of the two springs after moving upward, so that the arc block 56 can follow the movement of the chain assembly 4 to reciprocate up and down, and the tops of the two cylinders 54 are respectively connected to the first air pipe 57, the two first air pipes 57 pass through the mounting plate 53, and the two first air pipes 57 are connected to the second air pipe 58 through a tee, and the end of the second air pipe 58 away from the first air pipe 57 is connected to the third air pipe 59 and the fourth air pipe 65 through a tee, and the third air pipe 59 is connected to the material box 51, and the material box 51 is installed on A No. 1 liquid pipe 510 is installed, and the No. 1 liquid pipe 510 is connected to two No. 2 liquid pipes 511 through a tee. The outer wall of the arc block 56 is connected to a mounting rod 512. Two atomizing nozzles 513 are installed at the bottom of the mounting rod 512. One section of the two No. 2 liquid pipes 511 is located in the mounting rod 512. The two No. 2 liquid pipes 511 are respectively connected to the two atomizing nozzles 513. The material box 51 uses the positive pressure principle to transport the dry chain oil to the two No. 2 liquid pipes 511 through the No. 1 liquid pipe 510. The two No. 2 liquid pipes 511 spray the dry chain oil through the two atomizing nozzles 513. Valves are respectively provided on the No. 3 air pipe 59 and the No. 4 air pipe 65. The No. 3 air pipe 59 and the No. 4 air pipe 65 are respectively provided with valves. The valve 5 can adjust the air intake of the No. 3 air pipe 59 and the No. 4 air pipe 65. The cylinder 54 is provided with a one-way air inlet, and the two cylinders 54 are supplemented with air through the one-way air inlet. The two atomizing nozzles 513 are arranged in a mirror image. The two atomizing nozzles 513 move upward and spray the dry chain oil around the sleeve 42 while moving. After the two atomizing nozzles 513 move upward, they do not block the movement trajectory of the chain assembly 4. By spraying the dry chain oil from both sides of the sleeve 42, the outer wall of the sleeve 42 can be more evenly adhered to the dry chain oil. After the sleeve 42 is adhered to the dry chain oil, the friction between the sleeve 42 and the sprocket 2 is reduced, thereby achieving a lubrication effect and reducing wear.The outer wall of the material box 51 is rotatably mounted with a screw rod 514 through a bracket, and a spoiler impeller 516 is connected to the bottom of the screw rod 514. The spoiler impeller 516 is located between the two atomizing nozzles 513. The outer wall of the screw rod 514 is provided with a threaded groove 515, and the inner wall of the mounting rod 512 is provided with a ball. The inner wall of the mounting rod 512 is slidably connected with the threaded groove 515 through the ball. When the mounting rod 512 reciprocates up and down, due to the threaded groove 515 and the inner wall of the mounting rod 512, the A ball is provided at the connection of the wall. When the ball in the mounting rod 512 moves up and down, the ball presses against the thread groove 515, so that the thread groove 515 slides along the ball. When the thread groove 515 slides along the ball, the screw rod 514 rotates along the thread of the thread groove 515. The mounting rod 512 drives the screw rod 514 to rotate through the cooperation of the ball and the thread groove 515. When the spoiler impeller 516 rotates, it fans the dry chain oil sprinkled on the sleeve 42 to the surroundings. , so that the dry chain oil is scattered on the chain link 41, and a small amount of dry chain oil is attached to the connection between adjacent chain links 41, which can reduce the wear between the chain links 41. Through the cooperation of the chain assembly 4 and the lubricating assembly 5, during the operation of the chain assembly 4, the two atomizing nozzles 513 can spray the dry chain oil around the sleeve 42 from both sides, thereby reducing the friction between the sleeve 42 and the sprocket 2, achieving the effect of reducing wear and noise, and the dry chain oil is not easy to adhere to dust, so that the chain assembly 4 is relatively tidy. The two atomizing nozzles 513 replenish the dry chain oil in small amounts and multiple times, reducing the operation steps of manual oiling; through the setting of the spoiler impeller 516, the spoiler impeller 516 can fan the dry chain oil sprayed by the two atomizing nozzles 513 to the surroundings, so that the dry chain oil is attached to the chain link 41, lubricates the connection parts of adjacent chain links 41, and reduces the wear and noise between different chain links 41. ;

[0039] Further, see Figure 8 - Fig. 9The recovery component 6 is used to recover the dripping dry chain oil. The recovery component 6 is arranged on the mounting base 1. The recovery component 6 includes a recovery bucket 61. The recovery bucket 61 is mounted on the mounting base 1 through a bracket. The dry chain oil not attached to the chain component 4 falls into the recovery bucket 61 by its own gravity. The recovery bucket 61 is located below the two atomizing nozzles 513. The bottom of the recovery bucket 61 is connected to a No. 1 return pipe 62. A one-way valve 63 is installed on the No. 1 return pipe 62. The one-way valve 63 droops by gravity under normal conditions, so that the one-way valve 63 is in an open state. After the air pressure in the reflux bin 64 rises, the gas pushes up the one-way valve 63 from bottom to top, and the one-way valve 63 is in a closed state. The end of the No. 1 return pipe 62 is away from the recovery bucket 61 It is connected to a reflux bin 64, to which a No. 2 reflux pipe 66 is connected, a No. 4 air pipe 65 is connected to the reflux bin 64, and one end of the No. 2 reflux pipe 66 away from the reflux bin 64 is connected to the feeding port 52. The reflux bin 64 utilizes the positive pressure principle to transport the dry chain oil inside it to the feeding port 52 through the No. 2 reflux pipe 66, thereby achieving the effect of recycling the dry chain oil. A filter is provided inside the feeding port 52, which plays a filtering role. Through the setting of the recovery component 6, the recovery bucket 61 can collect the dry chain oil not attached to the chain component 4, and then transport it to the material box 51 through the reflux bin 64 and the No. 2 reflux pipe 66, thereby achieving the effect of recycling the dry chain oil and reducing resource loss.

[0040] For further information, see Fig.10 - Fig.12, a cleaning assembly 7 is used to clean the chain assembly 4. The cleaning assembly 7 is arranged on the mounting seat 1. The cleaning assembly 7 includes a mounting frame 72. Two outer covers 73 are installed on the mounting frame 72. Two rotating shafts 74 are rotatably installed on the mounting frame 72. The two rotating shafts 74 respectively penetrate the two outer covers 73. The two rotating shafts 74 are rotatably connected to the two outer covers 73 respectively. The outer walls of the two rotating shafts 74 are respectively connected with flexible rollers 79. The flexible rollers 79 are made of flexible material and can be deformed according to the objects they contact. The two flexible rollers 79 are respectively located inside the two outer covers 73. One section of the chain assembly 4 is located between the two flexible rollers 79. The outer wall of the outer cover 73 located above is rotatably installed with a driven shaft through a bracket. The driven shaft 75 is rotatably connected with a toothed ring 76, and the outer wall of the arc block 56 is connected with a rack 71. The toothed ring 76 meshes with the rack 71. The inner wall of the toothed ring 76 is provided with a ratchet, and the outer wall of the driven shaft 75 is provided with a pawl. The ratchet and the pawl are in contact. The cooperation between the ratchet of the toothed ring 76 and the pawl of the driven shaft 75 enables the toothed ring 76 to only drive the driven shaft 75 to rotate in one direction. When the toothed ring 76 reciprocates, the driven shaft 75 is driven to rotate in one direction intermittently through the cooperation of the ratchet and the pawl. A first belt 77 is sleeved between the driven shaft 75 and the rotating shaft 74 located above, and a second belt 78 is sleeved between the two rotating shafts 74. Multiple chain links 41 and multiple sleeves 42 are sequentially connected with two flexible sleeves during the movement. The chain assembly 4 is in contact with the two flexible rollers 79. During the movement, the multiple chain links 41 and the multiple sleeves 42 achieve the cleaning effect by contacting with the two flexible rollers 79. Since the flexible rollers 79 are constantly rotating, the contact surface between the flexible rollers 79 and the chain assembly 4 is also constantly changing, so as to avoid long-term contact with the same contact surface, which may cause excessive accumulation of dirt on the contact surface and affect the cleaning effect. A collection box 710 is installed on the outer cover 73, and a scraper 711 is installed on the collection box 710. The scraper 711 contacts the flexible rollers 79. A pull-out box 712 is slidably installed on the inner wall of the collection box 710. The scraper 711 scrapes the dust attached to the flexible rollers 79 onto the outer cover 73 through contact with the flexible rollers 79. The collection is carried out in the collection box 710, and the pull-out box 712 in the collection box 710 can be pulled out, so that the staff can clean it regularly. Through the setting of the cleaning component 7, the two flexible rollers 79 can clean the chain links 41 and the sleeves 42 of the chain component 4 during the operation of the chain component 4, so as to maintain the surface cleanliness of the chain links 41 and the sleeves 42, and at the same time be beneficial to the adsorption of dry chain oil. Through the setting of the two collection boxes 710 and the two scrapers 711, the two scrapers 711 can clean the two flexible rollers 79 respectively, so as to maintain the cleanliness of the contact surface between the flexible roller 79 and the chain component 4, and avoid the flexible roller 79 from being attached to a lot of dirt on the surface after long-term use, thereby affecting the cleaning effect.

[0041] With the above structure, the working principle of this case is that after the chain assembly 4 is sleeved on the two sprockets 2, the hydraulic cylinder is started to lift the tensioning wheel 3 upward, and the tensioning wheel 3 supports the chain assembly 4 upward, so that the chain assembly 4 is tightened on the two sprockets 2 and the tensioning wheel 3, and the driving mechanism in the mounting seat 1 drives one of the sprockets 2 to rotate, and one of the sprockets 2 drives the other sprocket 2 to rotate through the chain assembly 4, so as to achieve a transmission effect; after the two chain links 41 are connected by the pin 43, the two floating seal rings 44 of the same group are fitted together, and the two floating seal rubber rings 45 on the two floating seal rings 44 are squeezed by the two chain links 41 respectively, so that the two floating seal rubber rings 45 squeeze the two floating seal rings 44 respectively, so that the two floating seal rings 44 are fitted and closed, and since lubricating oil is provided between the pin 43 and the sleeve 42, the two floating seal rings 44 are also adhered to the lubricating oil, and the two floating seal rings An oil film is formed on the inner wall of 44, so that the two floating seal rings 44 can achieve a sealing effect after being fitted together. The two floating seal rubber rings 45 also have a certain sealing effect. The floating seal ring 44 is made of a metal material with small deformation. Through the arrangement of two groups of floating seal rings 44, the connection parts of the pin shaft 43, the sleeve 42 and the chain link 41 are effectively sealed to prevent the lubricating oil in the pin shaft 43 and the sleeve 42 from leaking out. The prior art usually uses rubber rings for sealing, but the rubber ring is easily deformed and damaged due to long-term wear during use, and has a short service life. Through the arrangement of the floating seal ring 44, the two floating seal rings 44 with small deformation can achieve and optimize the sealing effect through the cooperation with the two floating seal rubber rings 45, and the noise generated is low and the service life is long, thereby optimizing the internal lubrication effect of the chain assembly 4 and extending the service life of the chain assembly 4.

[0042] The material box 51 is filled with dry chain oil, and the staff can add dry chain oil through the feeding port 52. When the chain assembly 4 rotates following the sprocket 2, the multiple sleeves 42 contact the arc block 56 in sequence. When the sleeve 42 contacts the arc block 56, the outer wall of the sleeve 42 contacts the arc surface of the arc block 56, so that the sleeve 42 squeezes the arc block 56 upward when moving, achieving the effect of pushing the arc block 56 upward. When the arc block 56 moves upward, it drives the two pistons 55 to move upward. When the two pistons 55 move upward, they squeeze the two The air in the cylinder 54 is squeezed and transported to the No. 2 air pipe 58 through the two No. 1 air pipes 57 on the mounting plate 53. The No. 2 air pipe 58 transports the air to the No. 3 air pipe 59 and the No. 4 air pipe 65 through the three-way connection. The No. 3 air pipe 59 injects the air into the material box 51. The material box 51 uses the positive pressure principle to transport the dry chain oil to the two No. 2 liquid pipes 511 through the No. 1 liquid pipe 510. The two No. 2 liquid pipes 511 spray the dry chain oil through the two atomizing nozzles 513, and move back and forth up and down on the arc block 56. When the arc block 56 moves upward, the arc block 56 drives the mounting rod 512 to move synchronously, and the mounting rod 512 drives the two atomizing nozzles 513 to move synchronously. When the arc block 56 is located between two adjacent sleeves 42, the arc block 56 is located at the lowest point, and the two atomizing nozzles 513 are respectively located on the left and right sides of one of the sleeves 42. When the arc block 56 starts to move upward, the two atomizing nozzles 513 move upward and spray the dry chain oil around the sleeve 42 while moving. After the two atomizing nozzles 513 move upward, they do not block the chain assembly 4. Movement trajectory, when the two atomizing nozzles 513 follow the arc block 56 to move downward, the two cylinders 54 replenish air through the one-way air inlet, and the two atomizing nozzles 513 are located on both sides of another sleeve 42. During the movement of the atomizing nozzles 513, they do not contact the sleeve 42. By spraying dry chain oil from both sides of the sleeve 42, the dry chain oil can be more evenly attached to the outer wall of the sleeve 42. After the sleeve 42 is attached with dry chain oil, the friction between the sleeve 42 and the sprocket 2 is reduced, thereby achieving a lubrication effect and reducing wear;When the mounting rod 512 reciprocates up and down, since a ball is provided at the connection between the thread groove 515 and the inner wall of the mounting rod 512, when the ball in the mounting rod 512 moves up and down, the ball presses against the thread groove 515, causing the thread groove 515 to slide along the ball. When the thread groove 515 slides along the ball, the screw rod 514 rotates along the thread of the thread groove 515. The mounting rod 512 drives the screw rod 514 to rotate through the cooperation of the ball and the thread groove 515, and the screw rod 514 drives the spoiler impeller 516 to rotate. When the spoiler impeller 516 rotates, it fans the dry chain oil sprinkled on the top of the sleeve 42 to the surroundings, so that part of the dry chain oil sprinkles on the chain link 41. A small amount of dry chain oil attached to the connection between adjacent chain links 41 can reduce the wear between the chain links 41 and extend the service life of the chain assembly 4. The valves of the No. 3 air pipe 59 and the No. 4 air pipe 65 can adjust the No. 3 air pipe 59 and the No. 4 air pipe 65. The air intake of the air pipe 65 can adjust the spraying amount of the dry chain oil and the reflux amount of the dry chain oil; through the cooperation of the chain assembly 4 and the lubricating assembly 5, the two atomizing nozzles 513 can spray the dry chain oil around the sleeve 42 from both sides of the sleeve 42 during the operation of the chain assembly 4, thereby reducing the friction between the sleeve 42 and the sprocket 2, achieving the effect of reducing wear and noise, and the dry chain oil is not easy to adhere to dust, making the chain assembly 4 tidy, and the two atomizing nozzles 513 replenish the dry chain oil in small amounts and multiple times, reducing the operation steps of manual oiling; through the setting of the spoiler impeller 516, the spoiler impeller 516 can fan the dry chain oil sprayed by the two atomizing nozzles 513 to the surroundings, so that the dry chain oil adheres to the chain link 41, lubricates the connection parts of adjacent chain links 41, and reduces the wear and noise between different chain links 41. ;

[0043] The dry chain oil not attached to the chain assembly 4 falls into the recovery bucket 61 by its own gravity. The one-way valve 63 sags by gravity under normal conditions, so that the one-way valve 63 is in an open state. The dry chain oil in the recovery bucket 61 flows into the No. 1 return pipe 62 after accumulation. The dry chain oil in the No. 1 return pipe 62 flows into the return bin 64. When the No. 2 air pipe 58 delivers gas, the No. 2 air pipe 58 injects air into the return bin 64 through the No. 4 air pipe 65. After the air pressure in the return bin 64 rises, part of the air flows into the No. 1 return pipe 62, so that the gas pushes up the one-way valve 63 from bottom to top. The one-way valve 63 It is in a closed state to prevent the dry chain oil from flowing back. The reflux bin 64 utilizes the positive pressure principle to transport the dry chain oil inside it to the feeding port 52 through the No. 2 reflux pipe 66, thereby achieving the effect of recycling the dry chain oil. The filter screen in the feeding port 52 plays a filtering role to prevent impurities mixed in the recovered dry chain oil from entering the material box 51; through the setting of the recovery component 6, the recovery bucket 61 can collect the dry chain oil not attached to the chain component 4, and then transport it to the material box 51 through the reflux bin 64 and the No. 2 reflux pipe 66, thereby achieving the effect of recycling the dry chain oil and reducing resource loss.

[0044] The arc block 56 drives the rack 71 to move up and down when it moves back and forth. Due to the cooperation between the ratchet wheel of the gear ring 76 and the pawl of the driven shaft 75, the gear ring 76 can only drive the driven shaft 75 to rotate in one direction. When the rack 71 moves up and down, it drives the gear ring 76 to rotate back and forth. When the gear ring 76 rotates back and forth, it drives the driven shaft 75 to rotate in one direction intermittently through the cooperation of the ratchet wheel and the pawl. When the driven shaft 75 rotates, it drives the rotating shaft 74 located above to rotate through the No. 1 belt 77. The rotating shaft 74 located above is driven by The second belt 78 drives another rotating shaft 74 to rotate, so that the two rotating shafts 74 on the mounting frame 72 can rotate synchronously. When the two rotating shafts 74 rotate, they respectively drive the two flexible rollers 79 to rotate. One section of the chain assembly 4 is located between the two flexible rollers 79. The flexible roller 79 is made of flexible material and can be deformed according to the object it contacts. During the movement of the chain assembly 4, multiple chain links 41 and multiple sleeves 42 achieve a cleaning effect by contacting the two flexible rollers 79. Since the flexible rollers 79 are in the The continuous rotation causes the contact surface between the flexible roller 79 and the chain assembly 4 to change continuously, so as to avoid the same contact surface from being in contact for a long time and causing excessive dirt to accumulate on the contact surface and thus affecting the cleaning effect; when the flexible roller 79 rotates, the scraper 711 scrapes the dust attached to the flexible roller 79 into the collection box 710 on the outer cover 73 through contact with the flexible roller 79, and the pull-out box 712 in the collection box 710 can be drawn out, so as to facilitate the staff to clean it regularly; through the setting of the cleaning assembly 7, the two flexible rollers 79 can clean the chain links 41 and the sleeve 42 of the chain assembly 4 during the operation of the chain assembly 4, so as to maintain the surface cleanliness of the chain links 41 and the sleeve 42, and at the same time facilitate the adsorption of dry chain oil; through the setting of the two collection boxes 710 and the two scrapers 711, the two scrapers 711 can clean the two flexible rollers 79 respectively, so as to maintain the cleanliness of the contact surface between the flexible roller 79 and the chain assembly 4, so as to avoid the flexible roller 79 from being attached with a lot of dirt on its surface after long-term use and thus affecting the cleaning effect.
