Description

Technical Field

[0001] This utility model relates to the field of power transmission technology, specifically to a double-tooth chain winding power stable synchronous transmission device. Background Technology

[0002] The statements in this section are merely to provide background information related to the technical solutions of this application to aid understanding, and do not necessarily constitute prior art for the technical solutions of this application.

[0003] The basic principle of chain winding is to transmit power through the meshing between the chain and sprockets. In chain winding applications, a suitable winding method is crucial for ensuring transmission efficiency and extending service life. A chain typically consists of a series of links, each composed of inner and outer chain plates and a pin. Traditional power chain transmission systems transmit power sequentially through multiple sets of segmented single-chain linkages. Each linkage consists of two sprockets and a closed-loop single chain. The chain is wound around the outer edge of the sprockets and meshes with their teeth to transmit power. The linkages are interconnected through cross-linking of their sprockets, thus achieving continuous power transmission. This traditional power chain transmission system uses multiple sets of single chains to drive transmission sequentially, resulting in unstable operating speeds. It is difficult to ensure the stability of materials (especially long materials) during rapid transport, hindering smooth material transport and increasing the risk of chain derailment, thus limiting the system's usability. Utility Model Content

The power output wheel and the guide wheels are rotatably connected to the frame. The transmission rollers are supported above the frame by bearings. The multiple driven wheels are respectively fixedly connected to one end of the multiple transmission rollers. The transmission rollers can rotate under the drive of the driven wheels. The power output wheel, guide wheels, driven wheels, and chain adjusting wheels each have teeth. The double-toothed chain meshes with the teeth of the power output wheel, guide wheels, driven wheels, and chain adjusting wheels, and is connected in series with the power output wheel, guide wheels, driven wheels, and chain adjusting wheels. A guide wheel is arranged between two adjacent driven wheels, and the guide wheel is positioned lower than the two adjacent driven wheels. The chain adjusting wheel is arranged between two guide wheels, and the chain adjusting wheel is positioned lower than the two guide wheels.

[0005] In one embodiment, the power output wheel is disposed between two guide wheels, and the position of the power output wheel is lower than that of the two guide wheels.

[0006] In one embodiment, a guide wheel is provided below each of the two driven wheels located at both ends of the plurality of driven wheels.

[0007] In one embodiment, the power output wheel, guide wheel, driven wheel, and chain adjusting wheel are double-tooth chain discs.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

Figure 2A top view schematic diagram of a double-toothed chain winding dynamic stabilizing synchronous transmission device according to one embodiment is shown. For clarity, Figure 2 The toothed chain in the transmission device is not shown in the diagram. For details on the specific winding method of the toothed chain, please refer to [link / reference needed]. Figure 1 .

[0018] The double-toothed chain winding power stable synchronous transmission device includes a frame 1, a double-toothed chain 2, a power motor (not shown in the figure), a power output wheel coupled to the power motor, multiple guide wheels, multiple driven wheels, a chain adjusting wheel, and multiple transmission rollers 3. The double-toothed chain 2 is a closed chain with its ends connected.

[0019] The power output wheel and guide wheel are rotatably connected to the frame 1. The transfer roller 3 is supported above the frame 1 by bearings, and multiple driven wheels are fixedly connected to one end of each of the multiple transfer rollers 3. The transfer roller 3 can rotate under the drive of the driven wheels, thereby conveying the material above it.

[0020] The power output wheel, guide wheel, driven wheel, and chain adjusting wheel each have teeth, and the double-toothed chain 2 meshes with the teeth of the power output wheel, guide wheel, driven wheel, and chain adjusting wheel. In this way, all the power output wheels, guide wheels, driven wheels, and chain adjusting wheels in the transmission device are connected in series through the double-toothed chain 2.

[0021] The guide wheel is used to change the direction of the double-toothed chain 2. Along the double-toothed chain 2, a guide wheel is positioned between two adjacent driven wheels, and this guide wheel is lower than the two adjacent driven wheels. A chain adjusting wheel is positioned between two guide wheels, and the chain adjusting wheel is also lower than the two guide wheels.

[0022] In one embodiment, the power output wheel is positioned between the two guide wheels, and the position of the power output wheel is lower than that of the two guide wheels.

[0023] In one embodiment, a guide wheel is provided below each of the two driven wheels located at both ends of the plurality of driven wheels.

[0024] In one embodiment, the power take-off wheel, the chain adjusting wheel, and each driven wheel are guided by two guide wheels on both sides.

[0025] In one embodiment, the power output wheel, chain adjusting wheel, guide wheel, and driven wheel are double-tooth chain discs.

[0026] In one embodiment, the conveying roller 3 has a circumferential groove in its middle section to facilitate the stable conveying of cylindrical materials (such as aluminum rods). In another embodiment, the surface of the groove in the middle section of the conveying roller 3 is provided with an anti-slip texture or an anti-slip pad to increase the friction between the conveyed items and prevent the items from slipping during conveying.

[0027] The chain adjusting wheel is used to adjust the tension of the double-toothed chain 2. Chain tension affects the efficiency and reliability of the chain drive. An overly tight chain increases wear and load, while an overly loose chain may cause tooth skipping or chain derailment. The chain adjusting wheel changes the chain preload to ensure the chain maintains proper tension. The chain adjusting wheel can be implemented using any feasible method in the art. In one embodiment, the position of the chain adjusting wheel can be changed, thus adjusting the chain tension to ensure the chain always maintains proper tension—neither too tight nor too loose—to guarantee smooth and efficient transmission.

[0028] In one embodiment, frame 1 is a rectangular frame, which can be used for conveying long materials. The rectangular frame can be processed and welded from 100×48×5.3Q235 channel steel. 500mm long channel steel is cut as support legs. Support legs are erected vertically to the ground at 1000mm intervals on the left and right, and horizontally at 500mm intervals in the front and back. The upper part of the support legs is horizontally welded to the ground with 100×48×5.3Q235 channel steel. The lower part of the support legs is horizontally reinforced with 100×48×5.3Q235 channel steel at 50mm above the ground, and horizontally reinforced with ribs on all sides. Finally, the frame is welded into a cuboid shape.

[0029] In one embodiment, the drive motor can be a self-locking 0.75kW conveyor motor, used to provide power to the entire transmission device. The drive motor can be fixedly installed in the middle of the rectangular frame, and the power transmission shaft of the drive motor is connected to a 150mm diameter double-tooth chain as the power output wheel using a pin key.

[0030] In one embodiment, the transmission roller is machined from high-carbon round steel with a diameter of 200mm and an overall length of 652mm. One end is machined into a concentric pin with a diameter of 35mm and a length of 50mm, and the other end is machined into a concentric pin with a diameter of 35mm and a length of 100mm. A 20mm indentation is created on the inner side, and a 30mm indentation on the outer side creates a concentric pin with different diameters. A snap-fit ​​groove is created 5mm on the outer side to facilitate later engagement with the sprocket bearing. After the transmission rollers are machined, bearings on both sides are used to distribute and fix multiple transmission rollers onto a rectangular frame. One end of each transmission roller extends beyond the rectangular frame and is connected to a 150mm diameter double-toothed sprocket using a pin key, serving as the driven wheel.

[0031] In one embodiment, a 150mm diameter double-toothed sprocket is used as a guide wheel and is fixed to the frame by a rotatable connection. In another embodiment, a 50mm long irregular shaft is machined from 35mm diameter high-carbon round steel. This shaft has a 20mm inner slab and a 30mm outer concentric shaft with different diameters. A snap-fit ​​groove is also cut at the outer 5mm. The irregular shaft is welded to the 300mm section from bottom to top of each rectangular frame support leg, and a 150mm diameter double-toothed sprocket is used as a guide wheel to connect to it using a key.

[0032] In one embodiment, the double-tooth chain is selected as 12A-2 double-tooth chain, and the conveyor chain is connected in series. The chain is connected in series with the power output wheel, chain adjusting wheel, guide wheel and driven wheel. The power output wheel and each driven wheel are guided by two guide wheels on both sides.
