Description

Technical Field

[0001] This utility model relates to the field of tensioning wheel technology, specifically an automatic tensioning wheel with a damping structure. Background Technology

[0002] The tensioning pulley is a follower pulley pressed on the belt to change the wrap angle of the pulley or control the belt tension. It is a tensioning device for belt drives. When the center distance of the belt cannot be adjusted, the tensioning pulley can be used to tension the belt. The automatic tensioning pulley uses a damping block and spring structure. The elasticity of the spring can keep the pulley in contact with the pulley, so that the belt is always kept taut.

[0003] Traditional automatic tensioners rely solely on the spring force for tensioning. However, when the belt drives the pulley to rotate, the spring force is relatively large, and the spring cannot adjust in time during rapid belt rotation, leading to increased belt wear. Therefore, to address this issue, an automatic tensioner with a damping structure is proposed. Utility Model Content

[0004] The purpose of this invention is to provide an automatic tensioning wheel with a damping structure to solve the problem of increased belt wear caused by the inability of the spring to adjust in time during the rapid rotation of the belt.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic tensioning wheel with a damping structure includes an elastic body and a deformation body. A connecting arm is mounted on one side of the elastic body via a first bolt. A rotating wheel is provided on the front left side of the connecting arm. A second bolt threadedly connected to the connecting arm is disposed inside the rotating wheel. A rubber sleeve is provided on the outside of the rotating wheel. The rubber sleeve has uniformly distributed deformation grooves. The deformation body is mounted on the outside of the rubber sleeve. Longitudinally arranged and uniformly distributed locking strips are fixedly connected to the outside of the rotating wheel. Longitudinally arranged and uniformly distributed locking grooves are provided inside the rubber sleeve. The locking strips are disposed in the locking grooves.

[0007] Preferably, the deformable body includes an arc-shaped plate and a connecting rod. The arc-shaped plate has connecting grooves on both its left and right sides. The connecting rod is rotatably connected in the connecting grooves of the arc-shaped plate. Several arc-shaped plates are connected by the connecting rod to form a ring structure.

[0008] Preferably, a retaining ball is fixedly connected to one side of the arc-shaped plate and arranged in a front-to-back manner. The rubber sleeve has evenly distributed positioning holes on its outer side, and the retaining ball is disposed in the positioning holes of the rubber sleeve.

[0009] Preferably, one side of the arc plate is fixedly connected with horizontally arranged and evenly distributed arc strips, and the outer side of the rubber sleeve is provided with evenly distributed arc grooves, with the arc strips disposed within the arc grooves provided in the rubber sleeve.

[0010] Preferably, the outer side of the rubber sleeve is tightly fitted with evenly distributed arc-shaped plates.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, by using a rotating wheel, rubber sleeve, deformation groove, arc plate, connecting groove, connecting rod, locking ball, arc strip, locking strip, locking groove, and positioning hole, the arc strip pushes the rubber sleeve to deform under the action of its own deformation groove during the belt tensioning process. This improves the deformation of the automatic tensioning wheel during the tensioning process and prevents increased belt wear caused by the spring not being able to compress in time. At the same time, when the arc plate moves, the connecting rod rotates to prevent the arc plate from falling off. During the tensioning process, the locking ball is locked in the positioning hole of the rubber sleeve to prevent the arc plate from falling off. The arc strip is set in the arc groove of the rubber sleeve to prevent the arc plate from shifting. The locking strip is set in the locking groove of the rubber sleeve to prevent the rubber sleeve from shifting. Attached Figure Description

[0019] 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.

[0020] Please see Figure 1-5 This utility model provides a technical solution:

[0021] An automatic tensioning wheel with a damping structure includes an elastic body 1 and a deformation body 8. A connecting arm 2 is installed on one side of the elastic body 1 by a first bolt 3. A rotating wheel 4 is provided on the front left side of the connecting arm 2. A second bolt 5, threadedly connected to the connecting arm 2, is provided through the rotating wheel 4. A rubber sleeve 6 is provided on the outside of the rotating wheel 4. The rubber sleeve 6 has uniformly distributed deformation grooves 7. The deformation body 8 is installed on the outside of the rubber sleeve 6. Longitudinally arranged and uniformly distributed locking strips 9 are fixedly connected to the outside of the rotating wheel 4. Longitudinally arranged and uniformly distributed locking grooves 10 are provided in the rubber sleeve 6. The locking strips 9 are placed in the locking grooves 10. Through this arrangement, the connecting arm 2 can be provided with elasticity by the spring and damping block provided in the elastic body 1, and the belt can be tensioned by the connecting arm 2 through the rotating wheel 4.

[0022] The deformable body 8 includes an arc-shaped plate 801 and a connecting rod 803. Connecting grooves 802 are provided on both the left and right sides of the arc-shaped plate 801. Connecting rods 803 are rotatably connected within the connecting grooves 802 of the arc-shaped plate 801. Several arc-shaped plates 801 are connected by connecting rods 803 to form a ring structure. A retaining ball 804 is fixedly connected to one side of the arc-shaped plate 801, arranged front to back. Positioning holes 12 are evenly distributed on the outer side of the rubber sleeve 6, and the retaining ball 804 is positioned within the positioning holes 12 of the rubber sleeve 6. Laterally arranged and evenly distributed arc-shaped strips 805 are fixedly connected to one side of the arc-shaped plate 801. Arc grooves 11 are evenly distributed on the outer side of the rubber sleeve 6, and the arc grooves 805 are positioned within the arc grooves 11 of the rubber sleeve 6. Inside the groove 11, the outer side of the rubber sleeve 6 is tightly fitted with evenly distributed arc-shaped plates 801. With this arrangement, during the tensioning process of the belt, the arc-shaped strip 805 pushes the rubber sleeve 6 to deform under the action of the deformation groove 7, thereby improving the deformation of this automatic tensioning wheel during the tensioning process. At the same time, when the arc-shaped plate 801 moves, the connecting rod 803 rotates to prevent the arc-shaped plate 801 from falling off. During the tensioning process, the retaining ball 804 is locked in the positioning hole 12 opened in the rubber sleeve 6 to prevent the arc-shaped plate 801 from falling off. The arc-shaped strip 805 is set in the arc groove 11 opened in the rubber sleeve 6 to prevent the arc-shaped plate 801 from shifting. The retaining strip 9 is set in the retaining groove 10 opened in the rubber sleeve 6 to prevent the rubber sleeve 6 from shifting.

[0023] Working process: When using this automatic tensioning wheel, first install the elastic body 1 in a suitable position, and then make the arc plate 801 on the outer side of the wheel 4 contact the belt. At this time, the belt pushes the wheel 4 to move through the arc plate 801 and the rubber sleeve 6. The wheel 4 drives the connecting arm 2 to rotate inside the elastic body 1. The spring inside the elastic body 1 uses its elastic force to drive the connecting arm 2 and the pulley to tension the belt. At this time, the damping block inside the elastic body 1 provides damping to the spring inside the elastic body 1, reducing the spring's rebound inertia. At the same time, the belt pushes the arc plate 801, and the arc plate 801... 01 The rubber sleeve 6 is deformed under the action of the deformation groove 7. When the arc plate 801 moves, the arc plate 801 drives the connecting rod 803 to rotate. The two ends of the connecting rod 803 rotate in the two arc plates 801 respectively. At this time, the arc plate 801 pushes the rubber sleeve 6 to deform. The elasticity of the rubber sleeve 6 itself buffers the belt, making the belt run more stably. At the same time, the ball 804 and the arc groove 11 prevent the arc plate 801 from sliding on the outside of the rubber sleeve 6, and the strip 9 prevents the rubber sleeve 6 from sliding on the outside of the wheel 4, making the automatic tensioning wheel more stable in use.
