Description

Technical Field

[0001] The utility model relates to the technical field of sprocket wheels, in particular to a driving sprocket wheel with high strength. Background Art

[0002] A sprocket is a wheel with cog-shaped sprocket teeth, which is used to mesh with blocks with accurate pitch on link chains or cables. Sprockets are widely used in mechanical transmission in chemical, textile machinery, food processing, instrumentation, petroleum and other industries. Sprockets rely on the meshing of sprocket teeth and chain links to transmit motion and power. They have the advantages of smooth transmission, easy installation and maintenance, and reliable operation. When the sprocket is transmitting, the chain links and sprockets have a relative speed at the moment of meshing, which will cause impact between the two. Due to the existence of impact, wear will occur between the sprocket and the chain links.

[0003] When a current sprocket is damaged, the gear chain needs to be repaired and replaced in time. However, since the sprocket is mostly an integral part, the sprocket needs to be replaced as a whole, resulting in a waste of materials during use. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a high-strength driving sprocket, which has the advantage of replacing sprocket components individually and avoids the problem of overall waste when replacing the sprocket.

[0007] The outer wall of the slot is clamped with a ring sleeve, the outer wall of the ring sleeve is fixedly connected with a gear chain, the side wall of the ring sleeve is threadedly connected with a plurality of first threaded bolts, and the first threaded bolts pass through the slot through the first threaded holes and extend to the inner cavity of the main body.

[0008] According to some embodiments, a connecting column is clamped on the inner wall of the main body, a plurality of second threaded holes are opened on the surface of the connecting column, and the first threaded bolt can extend to the inner cavity of the second threaded hole.

[0009] According to some embodiments, sleeves are fixedly connected to the side walls on both sides of the connecting column, and the side walls of the sleeves are provided with insertion holes.

[0010] According to some embodiments, a second threaded bolt is threadedly connected to the side wall of the sleeve, and the second threaded bolt passes through the sleeve.

[0011] According to some embodiments, the side wall of the sleeve is threadedly connected with a third threaded bolt, the third threaded bolt passes through the sleeve, and the second threaded bolt and the third threaded bolt are perpendicular to each other.

[0012] According to some embodiments, the first threaded holes, the first threaded bolts, and the second threaded holes are each provided in multiple groups and are evenly distributed with the center line of the main body as the axis.

[0013] Beneficial Effects

[0014] The utility model provides a high-strength driving sprocket, which has the following beneficial effects:
