Description

Technical Field

[0001] The utility model relates to the technical field of chain transmission equipment, in particular to a tensioning mechanism of chain transmission equipment. Background Art

[0002] A sprocket is a wheel with cog-type sprocket teeth, which is used to mesh with blocks with accurate pitch on link chains or cables. It is widely used in mechanical transmission in chemical, textile machinery, food processing, instrumentation, petroleum and other industries. The tooth shape of the sprocket must ensure that the chain links can enter and exit the meshing smoothly and freely, minimize the impact and contact stress of the chain links during meshing, and be easy to process. The sprocket material should ensure that the teeth have sufficient strength and wear resistance, so the sprocket tooth surface is generally heat treated to achieve a certain hardness.

[0003] After the existing sprocket has been working for a period of time, the chain will become loose. If the tightness of the sprocket is not adjusted in time, the chain may be separated from the rotating wheel. If the chain is running at high speed, it may be thrown out directly, posing a threat to the surrounding personnel and equipment. Therefore, we need to propose a tensioning mechanism for the chain transmission equipment. Utility Model Content
