Mechanical synchronizer for main driving motor of disc shear

Abstract

The invention provides a mechanical synchronizer for the main driving motor of a disc shear, applied to the metallurgical machinery industry. The overall mechanical synchronizer comprises a shear body, a main driving reducer, a main driving motor, a first crown gear coupling, a fixed-side rigid synchronizing shaft, a second crown gear coupling, a spline shaft, a spline housing and a third crown gear coupling, wherein the other end of the fixed-side rigid synchronizing shaft is connected with the third crown gear coupling; the output end of a moving-side cycloidal pinwheel reducer is connected with the second crown gear coupling; the second crown gear coupling is connected with the spline shaft, a middle supporting seat, the spline housing and the third crown gear coupling; the middle supporting seat adopts rolling bearings to support the spline housing; a guiding device which can be extracted or retracted in the spline housing is arranged at the head part of the spline shaft. The mechanical synchronizer has the advantages of novel and scientific design, convenient adjustment, assembly and disassembly, stable and safe synchronous operation, long service life, high motor synchronous control accuracy and high shearing precision of disc shear.

Description

technical field [0001] The invention relates to a mechanical synchronization device for a main drive motor of disc shears in the metallurgical machinery industry. The mechanism is mainly used for mechanical synchronization of the main drive motor of disc shears when the width of steel plates is sheared in the finishing zone of medium and heavy plate rolled steel products in the metallurgical industry. Background technique [0002] At present, the disc shear is the key equipment in the finishing area of ​​the medium and heavy plate rolling production line. It is mainly used for constant width shearing of medium and heavy steel plates. It can perform high-precision bilateral constant width shearing of steel plates with a thickness of 6-25mm. The cut waste edge is broken and collected by the edge cutter. This equipment has the advantages of straight and smooth shearing surface, small deformation, high geometric precision and fast shearing speed. Disc shears are composed of fix...

Problems solved by technology

However, there are many problems in this method, especially when the shearing speed is high and the width of the sheared steel plate varies greatly, because when the sheared steel plate is relatively narrow, the dynamic balance of the connecting shaft cannot be guaranteed at this time, and it is very easy to Dangerous, and because of the relatively large fluctuation range of plate width, it is very difficult to manufacture and process this kind of synchronous connection shaft
