[0002] A roller chain is a type of chain drive used to transmit mechanical power. It is widely used in household, industrial, and agricultural machinery, including plotters, motorcycles, bicycles, and conveyors. It consists of a series of short cylindrical rollers linked together and driven by a gear called a sprocket. It is a simple, reliable, and efficient power transmission device.

[0003] Existing circular roller chains (such as bicycle chains and industrial conveyor chains) cannot transmit power parallel to the horizontal plane. They can only achieve vertical, simple circular circulation, making it difficult to achieve complex paths such as serpentine paths to save space. They are unsuitable for small-space, highly complex layout scenarios such as semiconductor wafer transport and precision electronic assembly. Furthermore, they are made of carbon steel or low-alloy materials and are highly dependent on grease. Lubrication fails quickly at high temperatures and is prone to brittle fracture at low temperatures. Therefore, a transmission mechanism with high space utilization is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problems of existing annular roller chains, which sag due to gravity when transmitting power parallel to the horizontal plane, and vertical, simple annular cycles that are difficult to achieve complex paths such as serpentine patterns, making them unsuitable for small spaces and highly complex layouts. Furthermore, the materials used are highly dependent on grease, which leads to rapid lubrication failure at high temperatures and easy breakage at low temperatures. This invention provides a transmission mechanism with high space utilization.

[0007] Furthermore, the roller chain also includes an upper connecting component and a lower connecting component. The upper connecting component, the first branch chain body, the combined component, the second branch chain body, and the lower connecting component are connected in sequence. The upper connecting component is disposed on the outside of the guide groove. At least one second cut groove is also passed through the support frame. One of the second cut grooves is spatially connected to one of the guide grooves. The lower connecting component slides in one of the corresponding second cut grooves.

[0008] Furthermore, the roller chain is made of materials including stainless steel and ceramic.

[0009] Furthermore, at least one bottom groove extends through the support frame, and at least one protrusion is installed on both the upper connecting component and / or the lower connecting component, with the protrusion on the lower connecting component sliding within one of the bottom grooves.

[0025] A space-efficient transmission mechanism includes a roller chain 1 and at least one support frame 2. The roller chain 1 includes a first branch chain body 101, a second branch chain body 102, and a combined assembly 103. At least one guide groove 21 and at least one first cutting groove 22 are passed through the support frame 2. The guide groove 21 and the first cutting groove 22 are spatially connected. The first branch chain body 101 and the second branch chain body 102 slide in the guide groove 21, and the combined assembly 103 slides in the first cutting groove 22. The roller chain 1 adopts a two-part design of the first branch chain body 101 and the second branch chain body 102 to improve the load-bearing capacity. The groove width of the guide groove 21 is 1mm-2mm larger than the width of the roller chain 1 to reduce the sagging of the middle section of the chain and reduce the wear of the chain during operation.

[0026] like Figure 2 As shown, the roller chain 1 also includes an upper connecting component 104 and a lower connecting component 105. The upper connecting component 104, the first branch chain body 101, the combined component 103, the second branch chain body 102 and the lower connecting component 105 are connected in sequence. The upper connecting component 104 is disposed on the outside of the guide groove 21. At least one second cut groove 23 is also passed through the support frame 2. One of the second cut grooves 23 is spatially connected to one of the guide grooves 21. The lower connecting component 105 slides in one of the second cut grooves 23.

[0027] like Figure 1 As shown, the roller chain 1 is made of stainless steel and ceramic.

[0028] like Figure 4 As shown, at least one bottom groove 24 extends through the support frame 2, and at least one protrusion is installed on the upper connecting component 104 and / or the lower connecting component 105, with the protrusion on the lower connecting component 105 sliding in one of the bottom grooves 24.

[0029] like Figure 3 As shown, a drive wheel 3 and a follower wheel 4 are meshed on the roller chain 1. A drive shaft 5 is connected to the drive wheel 3. A coupling 6, a mounting flange 7, and a reducer 8 are fitted on the drive shaft 5. The end of the drive shaft 5 away from the drive wheel 3 is connected to a motor 9. The drive shaft 5 is made of high-strength alloy steel, including 40Cr and SUS stainless steel, and is heat-treated to ensure that it is not easily deformed under high torque. The teeth of the drive wheel 3 and the follower wheel 4 mesh precisely with the roller chain 1. The follower wheel 4 is distributed at the turning nodes of the transmission trajectory, which is suitable for complex movements such as circular and serpentine paths. The drive motor 9 is a servo motor with a rated speed of 3000 r / min. The reducer 8 has a reduction ratio of 5-20:1 and an output torque of 50-200 N·m, ensuring that the running speed of the roller chain 1 is stable at 0.5-5 m / min.

[0030] The mounting flange 7 is rigidly connected to the input end of the reducer 8. The coupling 6 is a flexible coupling style, which can compensate for radial and axial installation errors and reduce the impact of vibration on the transmission mechanism.

[0031] like Figure 3 As shown, a bearing housing 10 and a locking nut 11 are also fitted on the drive shaft 5. The locking nut 11 is threaded to the surface of the drive shaft 5. The bearing housing 10 is made of cast steel or SUS stainless steel. The locking nut 11 is a double nut structure and is used in conjunction with a locking washer to prevent the drive shaft 5 from axially moving during high-speed rotation. The amount of axial movement is ≤0.05mm.

[0032] like Figure 1 As shown, at least one mounting bracket 12 is installed on one side of each support frame 2, and a base 13 is connected to the side of each mounting bracket 12 away from the support frame 2. The base 13 is a non-removable plate or a removable plate.

[0033] like Figure 3 As shown, at least one connecting bracket 14 is connected to the upper connecting component 104, and at least one positioning block 15 is provided on the side of each connecting bracket 14 away from the upper connecting component 104.

[0034] In addition, a chain tensioning plate is connected to the roller chain 1 and installed on the slack side of the chain. The follower wheel 4 is pushed by the spring or bolt adjustment mechanism to compensate for the length deviation of the roller chain 1 caused by wear or temperature change in real time, so as to ensure that the chain tension is within a reasonable range and the sag is ≤2mm, avoiding skipping teeth or jamming.

[0035] Example 1: The drive motor 9 starts, and the power is transmitted to the coupling 6 through the reducer 8. The output end drives the transmission wheel 3 to rotate through the transmission shaft 5. The transmission wheel 3 meshes with the roller chain 1, driving the chain to form a serpentine trajectory along several follower wheels 4, performing a limited tracking motion to meet the complex transmission requirements in a small space. The chain tension plate monitors the tension of the roller chain 1. The roller chain 1 is supported by the support frame 2 and the guide groove 21. The first branch chain body 101 and the second branch chain body 102 slide in the guide groove 21. The combined assembly 103 slides in the first cut groove 22, and the lower connecting assembly 105 slides in the second cut groove 23. The guide groove 21 limits the direction of chain movement, reducing lateral sway, gravity sagging, and wear. The bearing in the bearing seat 10 ensures the stable rotation of the power transmission shaft 5, and the locking nut 11 prevents the shaft system from moving.

[0036] Example 2: The product is fixed on the roller chain 1 by the product positioning block 15 and the connecting frame 14 and moves synchronously with the roller chain 1. When the product approaches the target position by less than 1 mm, the external control system receives the position signal and drives the motor 9 to decelerate. After the product reaches the precise position, the motor 9 brakes with a braking accuracy of ±0.05 mm. The positioning block 15 achieves precise positioning of the product within ±0.5 mm.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
