Description

Technical Field

[0001] The utility model relates to the technical field of chain correction machines, in particular to a right pitch fine-tuning positioning mechanism of a chain correction machine. Background Art

[0002] In modern industrial production, chains are widely used, especially in conveying and transmission systems. However, during use, chains may have problems such as elongation, deformation or uneven pitch, which will affect the accuracy and stability of the mechanical system. Traditional chain correction methods often rely on manual operations or simple mechanical devices, which are not only inefficient but also difficult to achieve high-precision requirements.

[0003] A Chinese patent discloses a chain correction device (publication number: CN 203209624 U) comprising a stretching portion and a base portion with a spacing therebetween and capable of fixing and connecting a chain respectively, and is characterized in that a protective mechanism for shielding the chain when correcting the chain is provided between the stretching portion and the base portion. However, such a chain correction device may experience problems such as elongation, deformation or uneven pitch during use, making it difficult to meet different chain pitch requirements, thereby affecting the accuracy and stability of the mechanical system. Therefore, a right pitch fine-tuning positioning mechanism for a chain correction machine is required. Utility Model Content

This dual-component design allows for a more complex power transmission and speed adjustment mechanism. The first sprocket is associated with the active transmission sprocket pair to receive power from the worm gear reducer.

The first sprocket 5 is associated with the active transmission sprocket pair 10 to receive power from the worm gear reducer 2. The first gear 6 is associated with the second driven transmission gear pair to achieve precise torque and speed control, which is crucial to the positioning accuracy of the chain.

[0021] In this embodiment, the first sprocket sprocket speed ratio is 63 / 38=1.71, and the total speed ratio is 60×1.71=102.6.
