Description

Technical Field

[0001] The utility model relates to the technical field of synchronous pulleys, in particular to a detachable synchronous pulley. Background Art

[0002] Synchronous pulleys are widely used in cable and other industries due to their constant transmission ratio, high transmission efficiency, smooth transmission, buffering and shock absorption. However, in the layer stranding process of the optical cable industry, a large number of synchronous pulleys need to be installed on a transmission shaft on some stranding equipment. Due to the different working conditions of each synchronous pulley, the wear degree of each synchronous pulley is different. In order to prevent the occurrence of problems such as over-torque or even twisting of the optical cable caused by the wear of the synchronous pulley, it is necessary to replace the severely worn synchronous pulley in advance, but the removal of the synchronous pulley at this location is very troublesome. For the worn synchronous pulley, all the synchronous pulleys in front or behind and the bearing seat at the end need to be disassembled before the worn synchronous pulley can be removed. After replacing the new synchronous pulley, the previously removed synchronous pulley and bearing seat need to be reinstalled. The entire maintenance process requires a lot of time and energy, and also greatly reduces the production efficiency on site.

[0003] However, the patents under the existing technology have the following disadvantages:

[0004] The process of disassembling and installing the synchronous pulley of this utility model is too complicated, and the synchronous pulley needs to be selected and installed according to the bearing diameter of the bearing seat during installation. The synchronous pulley cannot be installed and fixed on the outside of bearings of different diameters, and lacks applicability. Utility Model Content

[0039] The adjusting ring assembly 4 includes: an adjusting ring 8, a rotating groove 7 is provided on one side of the wheel body 1, and the adjusting ring 8 is rotatably connected to the inner side of the rotating groove 7; a pushing plate 9, and the pushing plate 9 is fixedly connected to one side of the adjusting ring 8; and a gear 10, and the gear 10 is fixedly connected to the inner side of the adjusting ring 8.

[0040] The one-way locking assembly 5 includes: a fixed tube 12, which is fixedly connected to the inner side of the adjusting ring 8; a spring 13, one end of which is fixedly connected to the inner bottom end of the fixed tube 12; a sliding shaft 14, which is fixedly connected to one end of the spring 13, and the sliding shaft 14 is slidably connected to the fixed tube 12; a positioning block 15, which is fixedly connected to one end of the sliding shaft 14, and the positioning block 15 is meshed with the ratchet groove 11, and a push plate 16 is provided on one side of the positioning block 15.

[0041] The clamping and fixing assembly 6 includes: a threaded shaft 18, a rotating groove 2 17 is provided on the inner side of the wheel body 1, the threaded shaft 18 is rotatably connected to the inner side of the rotating groove 2 17, and the outer side of the threaded shaft 18 has two parts of threaded grooves and the thread directions of the two parts of the threaded grooves are opposite; a gear 2 19, the gear 2 19 is fixedly connected to one end of the threaded shaft 18, and the gear 2 19 is meshed with the gear 1 10; a connecting ring 20, the connecting ring 20 is threadedly connected to the outer side of the threaded shaft 18; a support rod 21, the support rod 21 is rotatably connected to both sides of the connecting ring 20 through a connecting shaft; an extrusion plate 23, a sliding groove 22 is provided on the inner side of the wheel body 1, the extrusion plate 23 is slidably connected to the inner side of the extrusion plate 23, the extrusion plate 23 is rotatably connected to the support rod 21 through a connecting shaft, a connecting rod 24 is provided on one side of the extrusion plate 23, and the connecting rod 24 is slidably connected to the wheel body 1; an anti-skid splint 25, the anti-skid splint 25 is fixedly connected to one end of the connecting rod 24, and a rubber anti-skid cushion is provided on the inner side of the anti-skid splint 25.
