Unloading belt pulley transmission mechanism used for multi-line cutting machine

Abstract

The invention discloses an unloading belt pulley transmission mechanism used for a multi-line cutting machine. The unloading belt pulley transmission mechanism comprises a rack provided with a mandrel, wherein two bearings are arranged on the rack; a belt pulley is supported on the bearing; the bearings consist of a first bearing and a second bearing which are arranged at the two ends of the rack respectively; a long spacing sleeve is arranged between the first bearing and the second bearing; the axial end face of the first bearing is fastened by a gland; the axial end face of the second bearing is fastened by a shielding cover; the rack and the long spacing sleeve are respectively provided with a lubricating oil channel for lubricating the first bearing and the second bearing; the belt pulley is fixedly connected with the mandrel by a connecting plate; and the mandrel is fixedly connected with the connecting plate by a tension sleeve. The transmission mechanism has the advantages that the stability and the processing precision of the apparatus are enhanced, and meanwhile, the failure rate and the repairing difficulty of the apparatus are reduced.

Description

technical field [0001] The invention belongs to the field of multi-wire cutting machines, and in particular relates to an unloading pulley transmission mechanism for multi-wire cutting machines. Background technique [0002] In traditional multi-wire cutting machine equipment, the pulley is usually directly connected to the transmission shaft, and the connection form is mostly a spline connection. Due to the fast operation speed of the multi-wire cutting machine equipment, the precision requirements for the processed products are also very high, so the stability and processing accuracy of the equipment are very high. In actual production, if the traditional belt pulley transmission method is adopted, the tension of the belt and the bending moment generated by the dynamic load will inevitably make the torque transmission of the mandrel unstable, resulting in the problem of reduced processing accuracy of the equipment. At the same time, the mandrel is subjected to the compreh...

AI Technical Summary

Problems solved by technology

In actual production, if the traditional pulley transmission method is adopted, the tension of the belt and the bending moment generated by the dynamic load will inevitably make the torque transmission of the mandrel unstable, resulting in the problem of reduced processing accuracy of the equipment.

At the same time, the mandrel is subjected to multiple forces for a long time, and the service life will be greatly reduced, resulting in a decrease in the service life of the overall equipment.
