AI Technical Summary

Technical Problem

The disassembly and assembly of the pressure roller shaft of the existing hose pump is complicated and inconvenient, and the direction of the connecting bolts is consistent with the radial direction of the rotor, which makes disassembly and assembly difficult.

Method used

The roller is fitted onto the axle to form a rotational fit with the axle. The radial suspension end of the rotor support arm is provided with an axle seat. The axle seat includes parallel support plates and a notch. The limiting surface is embedded in the side wall of the notch. The axle and the axle seat are fixedly connected by a locating pin, eliminating the complicated disassembly and assembly steps.

Benefits of technology

It improves the ease of disassembly and assembly of the hose pump pressure roller shaft, reduces production costs, extends equipment life, and increases production efficiency.
