AI Technical Summary
The existing grooved wheel mechanisms are severely worn due to rigid contact during long-term use, especially during large load forces, which will reduce the accuracy of assembly lines and production lines.
An intermittent groove wheel mechanism is designed. By providing a protective sleeve on the outside of the fixed column, the protective sleeve corresponds one by one to the fixed column, and can be replaced separately when worn seriously to avoid the replacement of the overall connecting wheel.
It effectively avoids deformation of the fixed column under large loads, extends the service life of the equipment, and only needs to replace the kit without changing the overall connecting wheel when the protective sleeve wears, reducing maintenance costs.
