Metal round-ring chain stretcher split-type pulley structure

Abstract

The invention relates to a metal round-ring chain stretcher, in particular to a metal round-ring chain stretcher split-type pulley structure, and belongs to the technical field of round-ring chain stretchers. The metal round-ring chain stretcher split-type pulley structure comprises a first pulley body and a second pulley body; at least one roller is rotatably connected with the outer side face ofthe first pulley body; at least one guide wheel is rotatably connected with the outer side face of the second pulley body; a synchronous wheel shaft is arranged at the bottom of the first pulley bodyand the bottom of the second pulley body; the two ends of the synchronous wheel shaft are correspondingly and rotatably connected with two synchronous wheel shaft seats, and the two synchronous wheelshaft seats of the two ends of the synchronous wheel shaft are correspondingly fixed to the bottom of the first pulley body and the bottom of the second pulley body; and the two ends of the synchronous wheel shaft are connected with synchronous gears. According to the metal round-ring chain stretcher split-type pulley structure, the structure is simple, compact and reasonable, the structural sizeof a pulley is reduced, the machining precision of a workpiece is improved, and the processing difficulty of a pulley mould cavity is reduced.

Description

technical field [0001] The invention relates to a metal circular chain stretching machine, in particular to a split pulley structure of the metal circular chain stretching machine, which belongs to the technical field of the metal circular chain stretching machine. Background technique [0002] At present, the chain size produced by the metal round link chain stretching machine is up to 48mm, and most of the pulleys of this stretching machine are integral structures. [0003] With the continuous development of industrial technology and the great increase of coal mining volume, coal mining enterprises gradually have a demand for larger-scale conveyors. The chain specification of the stretching machine has been expanded to 60mm, but such a large-scale stretching machine has higher requirements for the overall structure and mechanical strength of the machine. The chuck cavity of the integral pulley is generally processed by boring, but because the processed cavity is relativel...

AI Technical Summary

Problems solved by technology

The chuck cavity of the integral pulley is generally processed by boring, but because the processed cavity is relatively large and the length is relatively deep, the cutter head will be very large, and the corner arc of the chuck cavity design is small, so it is normal The boring process cannot guarantee the design requirements. For this reason, a large cavity hole is bored, and then the chuck seat is equipped in the cavity hole. With such a structure, the design structural size of the casting will decrease under the condition of ensuring the stress strength. The design is very large; the cavity of the pulley is also processed by wire cutting, but wire cutting processing, due to the wire frame height of the wire cutting equipment, the stroke of the worktable, the maximum weight of the workpiece, the processing position and the processing angle of the workpiece. There are many requirements, and it is difficult to process the overall cylinder seat of a large-scale stretching machine if it is designed

The existing integral block structure can no longer meet the requirements of new equipment
