Description

Technical Field

[0001] This utility model relates to the technical field of chain drive components, and in particular to an adjustable tension chain drive component. Background Technology

[0002] Chain drive assemblies are a common type of mechanical transmission widely used in bicycles, motorcycles, industrial equipment, conveyor systems, agricultural machinery, and other fields. The chain meshes with the sprocket for transmission without slippage (unlike belt drives), ensuring a precise average transmission ratio. They are suitable for applications requiring synchronization or timing control. They can transmit large torques and loads, making them suitable for heavy-duty, low-speed, or medium-speed conditions. They are highly adaptable to environments with oil, dust, high temperatures, and humidity, and with proper maintenance, can operate for extended periods under harsh conditions.

[0003] However, commonly available chain drive components have significant drawbacks: First, chain drive systems lack automatic tensioning mechanisms. Under long-term operation or fluctuating load conditions, the chain is prone to slack due to the lack of dynamic compensation mechanisms, leading to decreased transmission efficiency, poor chain-sprocket meshing, and even tooth skipping or detachment, severely impacting equipment stability and safety. Second, chain lubrication and maintenance suffer from design flaws. Lubricating oil easily splashes onto surrounding transmission components or the underlying structure, accelerating corrosion and wear on non-lubricated parts. Furthermore, the lack of a proper oil collection device causes disordered oil accumulation, increasing cleaning and maintenance workload and posing slippery hazards and environmental pollution risks. Therefore, designing an adjustable tension chain drive component is essential. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable tension chain drive assembly to address the shortcomings of existing chain drives that lack a tensioning device and a lubricating oil collection device.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an adjustable tension chain drive assembly, including a support base plate, an oil collecting concave plate, and a transmission chain. A connecting plate is fixedly connected to the support base plate, and a second motor is fixedly connected to the connecting plate. A threaded shaft is fixedly connected to the output end of the second motor, and a sleeve is threadedly connected to the threaded shaft. The sleeve is fixedly connected to a second support plate, and the second support plate is slidably connected to a sliding groove. The sliding groove is formed on a fixed base, and the fixed base is fixedly connected to the support base plate. A right support block and a left support block are fixedly connected to the support base plate, and an oil collecting concave plate is slidably connected to the right support block and the left support block. A sliding groove is formed on the oil collecting concave plate, and a right oil collecting device and a left oil collecting device are respectively provided on the support base plate.

[0006] As a further technical solution of this utility model, a fixing plate is fixedly connected to the supporting base plate, a first motor is fixedly connected to the fixing plate, and a first protective device is fixedly connected to the output end of the first motor.

[0007] As a further technical solution of this utility model, a transmission belt is tightly attached to the first protective device, the transmission belt is tightly attached to the second protective device, and the second protective device is fixedly connected to the first rotating shaft.

[0008] As a further technical solution of this utility model, a drive sprocket is fixedly connected to the first rotating shaft, and a transmission chain is meshed with the drive sprocket.

[0009] As a further technical solution of this utility model, the first rotating shaft is rotatably connected to the first support plate, and the first support plate is fixedly connected to the support base plate.

[0010] As a further technical solution of this utility model, the transmission chain is meshed with a driven sprocket, and the driven sprocket is fixedly connected to the second rotating shaft.

[0011] As a further technical solution of this utility model, the second rotating shaft is rotatably connected to the second support plate.

[0012] This utility model provides an adjustable tension chain drive assembly, which has the following advantages: The first motor's output rotates, driving the first protective device to rotate, which in turn drives the transmission belt, which in turn drives the second protective device and the first rotating shaft to rotate, driving the drive sprocket to rotate, and finally driving the transmission chain to move. This allows for the transmission of large torque and load, and strong adaptability to environments such as oil, dust, high temperature, and humidity. When tensioning the transmission chain, the second motor's output rotates, driving the threaded shaft to rotate, which in turn drives the sleeve and the second support plate to move. By widening the gap between the drive sprocket and the driven sprocket, the transmission chain is tensioned. Under long-term operation or load fluctuation conditions, the chain will not slack due to the lack of a dynamic compensation mechanism, thus improving transmission efficiency and significantly enhancing the stability and safety of equipment operation. The oil collecting concave plate can collect the lubricating oil dripping from the transmission chain, flowing into the right and left oil collecting devices for centralized treatment. The oil collecting concave plate can be directly disassembled along the sliding groove for easy maintenance and cleaning, protecting non-lubricated parts and reducing cleaning and maintenance workload.

A threaded shaft 17 is fixedly connected to the output end of the second motor 20, and a sleeve 16 is threadedly connected to the threaded shaft 17. The sleeve 16 is fixedly connected to a second support plate 13, which is slidably connected to a sliding groove 23. The sliding groove 23 is formed on a fixed base 15, which is fixedly connected to the support base plate 1. A right support block 6 and a left support block 14 are fixedly connected to the support base plate 1. The right support block 6 and the left support block 14 are slidably connected to the oil collecting concave plate 8, which has a sliding groove 21. A right oil collecting device 7 and a left oil collecting device 7 are respectively provided on the support base plate 1. A fixed plate 22 is fixedly connected to the base plate 1, and a first motor 2 is fixedly connected to the fixed plate 22. A first protective device 24 is fixedly connected to the output end of the first motor 2, and the first protective device 24 serves as an anti-slip and protective device. A transmission belt 3 is tightly attached to the first protective device 24, and a second protective device 25 is tightly attached to the transmission belt 3. The second protective device 25 is fixedly connected to the first rotating shaft 4, and the second protective device 25 serves as an anti-slip and protective device. A drive sprocket 9 is fixedly connected to the first rotating shaft 4, and a transmission chain 10 is meshed with the drive sprocket 9.

[0020] Specifically, in use, the output end of the first motor 2 first rotates, driving the first protective device 24 to rotate, which in turn drives the transmission belt 3 to move, which in turn drives the second protective device 25 and the first rotating shaft 4 to rotate, driving the drive sprocket 9 to rotate, and finally driving the transmission chain 10 to move.
