Abstract
Description
Technical Field
[0001] The utility model relates to a herringbone synchronous belt transmission structure. Background Art
[0002] Synchronous belts are often used for cargo transport, leveraging friction between the belt and pulleys to drive the belt's rotation and move the items attached. To increase friction, the belt is typically equipped with teeth that engage with teeth on the pulleys. Belts and pulleys are also used in three-dimensional storage containers. The belts are vertically positioned for lifting and lowering. However, during this process, the parallel teeth are prone to tooth skipping due to the increased weight of the items attached. This creates a height difference between the two parallel belts, causing the items to tilt or even fall, posing a safety hazard. Furthermore, as the height of the container increases and the belt travel lengthens, the probability of tooth skipping also increases significantly. Utility Model Content

The herringbone patterns and the herringbone grooves cooperate with each other. A long central convex strip is provided in the center of the herringbone pattern, and an annular groove is provided on the pulley corresponding to the central convex strip. The central convex strip and the annular groove cooperate with each other.
[0005] Stoppers are evenly arranged on both sides of the belt.
[0006] The stop block is a wedge-shaped block structure.
[0007] The herringbone pattern includes a left diagonal pattern and a right diagonal pattern, and the position where the left diagonal pattern is connected to the central ridge and the position where the right diagonal pattern is connected to the central ridge are staggered; the pulley is divided into a left half wheel and a right half wheel by an annular groove, and the herringbone groove includes a left diagonal groove and a right diagonal groove, the left diagonal groove is arranged on the left half wheel, corresponding to the left diagonal pattern, and the right diagonal groove is arranged on the right half wheel, corresponding to the right diagonal pattern.
[0008] The diameter of the left half wheel is greater than the diameter of the right half wheel.
[0009] One end of the wheel shaft is connected to the belt pulley, and the other end is provided with a spline.
[0010] The beneficial effects are: the structural design of the utility model is reasonable and ingenious, and the friction between the belt and the pulley is increased by using the combination of herringbone patterns and herringbone grooves, and the combination of central convex fish annular grooves, thereby reducing the probability of tooth jumping of long-stroke belts and improving the stability of synchronous belt transmission.

[0017] like Figure 1 、 Figure 2The herringbone synchronous belt transmission structure shown includes a belt 4 and a pulley 1. The pulley 1 is connected to the wheel shaft 2. The surface of the belt 4 is arranged with several protruding herringbone patterns. Herringbone grooves are provided on the pulley 1 corresponding to the herringbone patterns. The herringbone patterns and the herringbone grooves cooperate with each other. A long central convex strip 5 is provided in the center of the herringbone pattern. An annular groove 13 is provided on the pulley 1 corresponding to the central convex strip. The central convex strip 5 and the annular groove 13 cooperate with each other.
[0018] Stoppers 8 are evenly spaced on both sides of the belt 4. These wedge-shaped stoppers 8 are connected to the belt 4 at their wider ends, and face the pulley 1 at their narrower ends. During the rotation of the pulley 1, the stoppers 8 on the belt 4 first contact the pulley 1. The pulley 1 then follows the inclined surfaces of the stoppers 8 and fits between the stoppers 8 on both sides before finally contacting the belt 4. This allows the belt 4 and pulley 1 to be aligned left and right at the pulley position.
[0019] The herringbone pattern includes a left twill 7 and a right twill 6, with the left twill 7 and the right twill 6 forming an angle of 120° to 175°, and the position where the left twill 7 is connected to the central ridge 5 and the position where the right twill 6 is connected to the central ridge 5 are staggered; Figure 2 As shown, the pulley 1 is divided into a left half wheel 12 and a right half wheel 11 by an annular groove 13. The herringbone groove includes a left oblique groove 14 and a right oblique groove 15. The left oblique groove 14 is arranged on the left half wheel 12, corresponding to the left oblique groove 7, and the right oblique groove 15 is arranged on the right half wheel 11, corresponding to the right oblique groove 6. The depth of the left oblique groove 14 and the right oblique groove 15 is 3 to 15 mm.
[0020] The diameter of the left half wheel 12 is greater than the diameter of the right half wheel 11 .
[0021] One end of the wheel shaft 2 is connected to the pulley 1, and the other end is provided with a spline 3.
[0022] The structural design of the utility model is reasonable and ingenious. It uses the combination of herringbone patterns and herringbone grooves, and the combination of central convex fish annular grooves to increase the friction between the belt and the pulley, reduce the probability of tooth jumping of the long-stroke belt, and improve the stability of synchronous belt transmission.
