Abstract
Description
Technical Field
[0001] This utility model relates to the field of chain technology, specifically a double-row self-lubricating roller chain. Background Technology
[0002] In the petroleum processing and production process, roller chains are often used in mechanical devices that need to transmit power or transport materials due to their wear resistance, high temperature resistance, and high load-bearing capacity.
[0003] Chinese Patent No. 200720130230.5 discloses a roller chain. It comprises a pin, an outer chain plate, an inner chain plate A, an inner chain plate B, a middle chain plate, bushings, and balls. Its distinguishing feature is that the thickness of the outer chain plate is increased from 2.4 mm to 3.0 mm. The thickness of the inner chain plate A is also increased from 2.4 mm to 3.0 mm.
[0004] During use, this invention cannot adjust the tension of the chain, resulting in the chain tension being uncontrollable. Summary of the Invention
[0005] The purpose of this invention is to provide a double-row self-lubricating roller chain to solve the problems mentioned in the prior art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a double-row self-lubricating roller chain, comprising a chain assembly; the chain assembly consists of a chain body, transmission toothed discs, guide toothed discs, and tension adjusting toothed discs; two transmission toothed discs are meshed and installed on both sides of the chain body; two guide toothed discs are meshed and installed on both sides of the bottom end of the chain body; the tension adjusting toothed disc is meshed and installed at the bottom middle of the chain body; a lubricating oil groove is installed at the bottom end of the tension adjusting toothed disc; the upper end of the lubricating oil groove is installed at the bottom end of a mounting frame; a tension adjusting mechanism is installed on the upper side of the mounting frame; and the tension adjusting toothed disc is rotatably installed at the bottom end of the tension adjusting mechanism.
[0007] Preferably, an applicator is provided inside the lubricating oil tank on both sides of the tension adjusting gear plate, and the applicator is rotatably installed on both sides inside the lubricating oil tank.
[0008] Preferably, the outer side of the applicator wheel is wrapped with a sponge cylinder.
[0009] Preferably, the controller has control buttons on its upper side, and a display is installed on the upper side of the controller, located to the side of the control buttons.
[0010] Preferably, the tension adjustment mechanism consists of a mounting frame and a telescopic rod, with the mounting frame installed at the bottom end of the telescopic rod and the tension adjustment gear plate installed at the bottom end of the mounting frame.
[0011] Preferably, a pressure sensor is installed at the bottom end of the telescopic rod, and the bottom end of the pressure sensor is mounted on the upper side of the mounting bracket.
[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The tension adjusting toothed disc engages at the bottom center of the chain body. By changing its position, the tension of the chain body can be adjusted to maintain a suitable tension and avoid being too loose or too tight. 2. The applicator wheels located on both sides of the tension adjusting toothed disc inside the lubricating oil tank rotate during chain operation as the chain contacts the tension adjusting toothed disc. This rotation continuously carries the lubricating oil from the lubricating oil tank out and evenly coats the tension adjusting toothed disc and the chain surface it contacts, achieving automatic lubrication of the chain, reducing friction and wear during operation, and extending the chain's service life. 3. When chain tension needs adjustment, the telescopic rod extends or retracts according to the control system's commands, causing the mounting frame to rise or fall. Since the tension adjusting gear is mounted at the bottom of the mounting frame, the raising or lowering of the mounting frame changes the position of the tension adjusting gear, thus altering the chain tension. This method allows for precise adjustment of the chain tension to meet different work requirements. 4. A pressure sensor is used to monitor the tension of the chain body in real time. During chain operation, the pressure sensor converts the detected chain tension into an electrical signal and transmits it to the control system. The control system determines whether the chain tension is appropriate based on the preset tension range and the received signal. If the tension is abnormal, the control system will issue a command to control the telescopic rod to extend or retract accordingly. By adjusting the position of the tension regulating disc, the chain tension is restored to the normal range, thereby ensuring the stable operation of the chain. Attached Figure Description

Detailed Implementation
[0015] 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.
[0016] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 In this embodiment of the present invention, a double-row self-lubricating roller chain includes a chain device 1. The chain device 1 consists of a chain body 2, transmission toothed discs 3, guide toothed discs 4, and tension adjusting toothed discs 5. Two transmission toothed discs 3 are engaged and installed on both sides of the chain body 2, two guide toothed discs 4 are engaged and installed on both sides of the bottom end of the chain body 2, and the tension adjusting toothed disc 5 is engaged and installed at the bottom middle of the chain body 2. A lubricating oil groove 8 is installed at the bottom end of the tension adjusting toothed disc 5, and the upper end of the lubricating oil groove 8 is installed at the bottom end of the mounting frame 6. A tension adjusting mechanism 7 is installed on the upper side of the mounting frame 6, and the tension adjusting toothed disc 5 is rotatably installed at the bottom end of the tension adjusting mechanism 7.
[0017] Inside the lubricating oil tank 8, on both sides of the tension adjusting gear disc 5, are application wheels 14. These wheels 14 are rotatably mounted on both sides of the lubricating oil tank 8. During the operation of the chain body 2, the application wheels 14 rotate due to the contact between the chain body 2 and the tension adjusting gear disc 5. The rotation of the application wheels 14 continuously carries out the lubricating oil from the lubricating oil tank 8 and evenly applies it to the tension adjusting gear disc 5 and the surface of the chain body 2 in contact with it, achieving automatic lubrication of the chain body 2, reducing friction and wear during operation, and extending the service life of the chain body 2. The application wheels 14 are wrapped with sponge cylinders. Utilizing the sponge's excellent absorbency and water retention properties, these sponge cylinders can absorb a large amount of lubricating oil from the lubricating oil tank 8. During the rotation of the coating wheel 14, the sponge cylinder contacts the surface of the chain body 2, and evenly releases and applies the adsorbed lubricating oil to the chain body 2. Compared with ordinary coating wheels 14, it can store and release lubricating oil more effectively, ensuring the continuous lubrication effect of the chain body 2.
[0018] Control buttons 15 are located on the upper side of the controller 9. A display 10 is mounted on the upper side of the controller 9, next to the control buttons 15. The control buttons 15 on the upper side of the controller 9 are used by the operator to input various control commands, such as start, stop, and speed adjustment. After receiving these commands, the controller 9 performs corresponding control on the operation of the equipment. The display 10 is used to display the equipment's operating parameters in real time, such as the running speed and tension value of the chain body 2, allowing the operator to intuitively understand the equipment's operating status and make timely adjustments and monitoring.
[0019] The tension adjustment mechanism 7 consists of a mounting frame 6 and a telescopic rod 11. The mounting frame 6 is installed at the bottom of the telescopic rod 11, and the tension adjustment gear 5 is installed at the bottom of the mounting frame 6. When it is necessary to adjust the tension of the chain body 2, the telescopic rod 11 extends or retracts according to the instructions of the control system, causing the mounting frame 6 to rise or fall. Since the tension adjustment gear 5 is installed at the bottom of the mounting frame 6, the rise and fall of the mounting frame 6 will change the position of the tension adjustment gear 5, thereby changing the tension of the chain body 2. In this way, the tension of the chain body 2 can be precisely adjusted to adapt to different working requirements. A pressure sensor 12 is installed at the bottom of the telescopic rod 11, and the bottom of the pressure sensor 12 is installed on the upper side of the mounting frame 6. The pressure sensor 12 is used to monitor the tension of the chain body 2 in real time. During the operation of the chain body 2, the pressure sensor 12 converts the sensed tension of the chain body 2 into an electrical signal and transmits it to the control system. The control system determines whether the tension of the chain body 2 is appropriate based on the preset tension range and the received signal. If the tension is abnormal, the control system will issue a command to control the telescopic rod 11 to perform corresponding telescopic movements. By adjusting the position of the tension regulating disc 5, the tension of the chain body 2 will be restored to the normal range, thereby ensuring the stable operation of the chain body 2.
[0020] The working principle and usage process of this utility model are as follows: During operation, the transmission toothed disc 3 transmits power to the chain body 2 through meshing with both sides of the chain body 2, driving the chain body 2 to perform transmission motion; the guide toothed disc 4 is installed on both sides of the bottom end of the chain body 2 to guide and constrain the movement direction of the chain body 2, ensuring that the chain body 2 runs stably along the predetermined path; the tension adjusting toothed disc 5 meshes with the middle bottom end of the chain body 2, and adjusts the tension of the chain body 2 by changing its position, so that the chain body 2 maintains a suitable tension, avoiding excessive looseness or tightness, and ensuring the stability and reliability of the chain body 2 transmission. The lubricating oil groove 8 is installed at the bottom end of the tension adjusting toothed disc 5 to store lubricating oil, and the chain body 2 extends into it to lubricate the chain body 2; the tension adjusting mechanism 7 on the upper side of the mounting frame 6 is responsible for controlling the raising and lowering of the tension adjusting toothed disc 5 to adjust the tension of the chain body 2.
[0021] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
