Description

Technical Field

[0001] The utility model relates to the technical field of synchronous wheels, and more specifically to a synchronous wheel with adjustable winding width. Background Art

[0002] A synchronous wheel usually refers to a synchronous belt pulley, which is a mechanical component used to transmit power. Announcement No. CN218377594U proposes an application No. 202122180811.2 in a synchronous wheel with adjustable winding width. A synchronous wheel with adjustable pitch is proposed. Because of its small adjustment width range, the synchronous wheel width is not practical and is inconvenient to change. Through the setting of the synchronous wheel and the movable adjusting plate, the screw nut on the outside of the limit ring is twisted. As the screw nut is screwed out, the circular clamping plate rises along the adjusting side plate of the circular aperture. The lifting of the clamping plate causes the tightening state between the movable adjusting plate and the synchronous wheel transmission tooth to become a loose and active state. At this time, the movable adjusting plate can be position adjusted along the direction of the synchronous wheel transmission tooth. After the positions of the two movable adjusting plates are adjusted, the adjusting screw is tightened so that the clamping plate is tightly pressed against the synchronous wheel transmission tooth, so that the limit ring can be fixed on the outside of the synchronous wheel, thereby easily realizing the width adjustment of the belt adaptation on the synchronous wheel.

[0003] However, the above-mentioned synchronous wheel needs to rotate the adjusting screw during the adjustment process. Since the synchronous wheel has a large number of transmission teeth, each transmission tooth corresponds to an adjusting screw, and a large number of adjusting screws need to be rotated, which makes the adjustment more troublesome. Utility Model Content

[0004] In order to overcome the above defects of the prior art, the utility model provides a synchronous wheel with adjustable winding width to solve the problems existing in the above background technology.

[0005] The utility model provides the following technical solutions: a synchronous wheel with adjustable winding width, comprising a wheel body and a movable disk, the wheel body being detachably mounted with a blocking ring, a plurality of synchronous racks being fixedly connected to the surface of the wheel body, a through-hole matching the synchronous rack being provided on the inner ring surface of the movable disk, the surface of the synchronous rack being overlapped with the inner wall of the through-hole, the inner ring surface of the movable disk being overlapped with the surface of the wheel body, a mounting ring being fixedly connected to the side surface of the movable disk, a hollow cylinder being fixedly connected to the inner ring surface of the mounting ring, a limiting ring being fixedly connected to the inner wall of the hollow cylinder, an inserting strip being slidably connected to the inner ring surface of the limiting ring, a moving ring being fixedly connected to the surface of the inserting strip, a first spring being fixedly connected to the opposite surface of the moving ring to the limiting ring, and a plurality of positioning grooves matching the inserting strip being provided on the surface of the synchronous rack;

[0006] A moving opening is provided on the surface of the mounting ring, the surface of the insert strip overlaps with the inner wall of the moving opening, the side of the insert strip is arc-shaped, the surface of the mounting ring is threadedly connected with an internal thread ring, a side of the internal thread ring close to the insert strip is fixedly connected with a push ring, a side of the push ring facing the insert strip is arc-shaped, and the inner ring surface of the push ring overlaps with the surface of the mounting ring.

[0007] A further solution is that a mounting groove is provided on the side of the wheel body, and a connecting block is fixedly connected to a side of the blocking ring close to the mounting groove, and the surface of the connecting block overlaps the inner wall of the mounting groove. There are two connecting blocks, which are symmetrically arranged on the side of the blocking ring, and a T-shaped groove is provided on the surface of the connecting block, and a T-shaped plug block is slidably connected to the inner wall of the T-shaped groove, and a second spring is fixedly connected to the opposite surface of the T-shaped plug block and the T-shaped slot, and a groove is provided on the inner wall of the mounting groove, and the surface of the T-shaped plug block overlaps the inner wall of the groove, and both sides of the T-shaped plug block are arc-shaped.

[0008] Technical effects and advantages of the utility model:

[0009] 1. The synchronous wheel with adjustable winding width, after the winding belt is placed, adjust the moving disk to a suitable blocking position, at this time the moving disk and the blocking ring can limit the winding belt, then rotate the internal threaded ring, the internal threaded ring drives the push ring to move, the arc surface of the push ring overlaps the arc surface of the insert strip, at this time the arc surface of the insert strip is stressed, the insert strip moves down, the moving ring squeezes the first spring, and the insert strip is inserted into the positioning groove of the synchronous rack, at this time the position of the moving disk is fixed, when adjustment is needed again, the internal threaded ring can be reversed to move the push ring out, at this time the elastic force of the first spring pushes the moving ring upward, thereby making the insert strip disengage from the positioning groove, and the moving disk can be moved again to adjust the position, so that the synchronous wheel can be conveniently adjusted according to the winding belt width.

[0010] 2. The synchronous wheel with adjustable winding width inserts the connecting block into the installation groove. At this time, the arc surface of the T-shaped plug block is forced to be accommodated in the T-shaped groove, and the second spring is squeezed. When the T-shaped plug block moves to the groove, the elastic force of the second spring pushes the T-shaped plug block to be inserted into the groove and pulls the blocking ring. At this time, the arc surface of the T-shaped plug block is forced to be accommodated in the T-shaped groove, thereby facilitating the disassembly and assembly of the blocking ring and the installation of the winding belt on the synchronous wheel.

[0018] Insert the connecting block 13 into the installation groove. At this time, the arc surface of the T-shaped plug 14 is forced to be accommodated in the T-shaped groove, and the second spring 15 is squeezed. When the T-shaped plug 14 moves to the groove, the elastic force of the second spring 15 pushes the T-shaped plug 14 to be inserted into the groove, pulling the blocking ring 3. At this time, the arc surface of the T-shaped plug 14 is forced to be accommodated in the T-shaped groove, thereby facilitating the disassembly and assembly of the blocking ring 3 and the installation of the winding belt on the synchronous wheel.

[0019] A plurality of synchronous racks 4 are fixedly connected to the surface of the wheel body 1, a through opening matched with the synchronous rack 4 is opened on the inner ring surface of the movable plate 2, the surface of the synchronous rack 4 overlaps with the inner wall of the through opening, the inner ring surface of the movable plate 2 overlaps with the surface of the wheel body 1, a mounting ring 5 is fixedly connected to the side of the movable plate 2, a hollow cylinder 6 is fixedly connected to the inner ring surface of the mounting ring 5, a limiting ring 7 is fixedly connected to the inner wall of the hollow cylinder 6, and an insert 8 is slidably connected to the inner ring surface of the limiting ring 7.

[0020] A moving ring 9 is fixedly connected to the surface of the insertion strip 8, and a first spring 10 is fixedly connected to the surface of the moving ring 9 opposite to the limiting ring 7.

Then, the internal threaded ring 11 is rotated, and the internal threaded ring 11 drives the push ring 12 to move. The arc surface of the push ring 12 overlaps the arc surface of the insertion strip 8. At this time, the arc surface of the insertion strip 8 is subjected to force, and the insertion strip 8 moves down.
