Description

Technical Field

[0001] The utility model relates to the technical field of spliced ​​sprocket wheels, in particular to a spliced ​​multi-row mechanism sprocket wheel. Background Art

[0002] A sprocket is a wheel with cog-shaped sprocket teeth, which is used to mesh with blocks with accurate pitch on a link chain or cable. Sprockets play an important role in mechanical transmission. They can transfer power from one shaft to another to realize the operation of mechanical equipment. This part is widely used in mechanical transmission in chemical industry, textile machinery, escalators, wood processing, multi-story parking garages, agricultural machinery, food processing, instrumentation, petroleum and other industries. According to the different characteristics and uses of sprockets, they can be divided into many types, such as single sprocket, double sprocket, helical gear sprocket, non-standard sprocket, plastic sprocket and stainless steel sprocket. The selection of suitable sprocket type depends on the specific transmission requirements. The working principle of the sprocket mainly depends on the characteristics of the gear and sprocket. They cooperate with each other so that energy can be transferred from one drive device to another. This working principle is very important in mechanical engineering and can achieve effective transmission of power and energy. The spliced ​​sprocket is a specially designed sprocket with a split structure, which allows the sprocket to be easily disassembled and assembled. This design makes the sprocket more flexible and convenient when repairing, replacing or adjusting it. The advantage of the spliced ​​sprocket lies in its maintainability and adjustability. Since it can be easily disassembled and assembled, when the sprocket is worn or fails, only the problematic part can be replaced or repaired without replacing the entire sprocket. In addition, according to specific transmission requirements, different transmission effects can be achieved by adjusting the splicing method of the sprocket.

[0003] The publication number is CN219994326U. A sprocket of a spliced ​​multi-row mechanism relates to the technical field of sprockets, including a plurality of first wheel cores and a second wheel core, the first wheel core and the second wheel core are both semicircular, and the ends of the first wheel core and the second wheel core are butted against each other, the plurality of first wheel cores and the second wheel cores are connected to the rotating shaft through a connecting mechanism, the outer surfaces of the first wheel core and the second wheel core are both installed with a gear ring, the gear ring is semicircular, and a plurality of teeth are equidistantly installed on the outer arc surface of the gear ring, the outer surfaces of the first wheel core and the second wheel core are both symmetrically provided with grooves, one end of the groove is provided with a limiting groove, a connecting block is provided inside the groove, and the connecting block is a U-shaped structure. The present application uses the connecting block By cooperating with the groove and the limit groove, the first wheel core and the second wheel core can be fixed together, thereby completing the splicing of the sprocket. When a certain sprocket is damaged, only the sprocket needs to be removed and replaced, without the need to remove the entire sprocket for replacement, thereby improving the use effect. In this scheme, the wheel core is divided into two parts, which are fixed to the rotating shaft by bolts. When the teeth on a certain gear ring are damaged and need to be replaced, half of it is removed, and the replaced half of the gear is aligned with the previous half of the gear and then installed. Some teeth that are not damaged are not used to the maximum extent, resulting in increased costs and waste of resources. For this reason, we propose a sprocket with a spliced ​​multi-row mechanism.
