In traditional roll squeezer structure, reductor hollow shaft generally adopts shrink disk structure with being connected of roll shaft.Be connected with reductor hollow shaft when needs disconnect roll shaft, carry out roller shell and base bearing while changing, usually occur the dismounting difficulty of reductor and roll shaft, and as easy as rolling off a log roll shaft is pulled, affect its result of use.
Application number is 201320324252.0(publication number 203404263U) utility model a kind of high-pressure roller mill compression roller roll shaft draw bail is disclosed, comprise extrusion roll shaft, decelerator hollow shaft, ring flange, flange shaft and expansion set shaft coupling, extrusion roll shaft is connected by key with ring flange, ring flange is connected closing by bolt with one end with flange in flange shaft, the other end of flange shaft is fitted in decelerator hollow shaft, and make between the other end of flange shaft and decelerator hollow shaft by expansion set shaft coupling fastening, as Fig. 2.This structure has been selected ring flange parts, has increased the difficulty of roll shaft processing, assembling, and has increased length and the weight of roll shaft.
Summary of the invention
This patent provides a kind of Quick disassembling structure of roll shafts of roll press for solving the technical problem existing in known technology, the accuracy of alignment of this structure is high, and easy accessibility.
A kind of Quick disassembling structure of roll shafts of roll press, comprise roll shaft, reductor hollow shaft, it is characterized in that: described reductor hollow shaft is coaxially connected with quick-detachment flange shaft by locking plate, quick-detachment flange shaft has a flange portion, quick-detachment flange shaft is directly connected with one end of roll shaft, quick-detachment flange shaft is provided with depression rim of the mouth in the one end being connected with roll shaft, the depression inwall in rim of the mouth and the outer circumference surface of roll shaft coordinate, central part in depression rim of the mouth is also provided with first keyway, on the end face of roll shaft, be also provided with the position second keyway corresponding with first keyway, between first keyway and second keyway, be provided with connecting key, on the bottom surface in depression rim of the mouth, be also provided with multiple first through holes, in first through hole, be coated with the first bolt that quick-detachment flange shaft is tightened together with roll shaft,
Roll shaft is installed in bearing block, on roll shaft, be also set with axle head baffle ring, axle head is when one end towards quick-detachment flange shaft of ring is provided with pit, and the second bolt that pit is threaded in quick-detachment flange shaft holds out against, the distribution of second bolt in flange portion is positioned at the outside of first bolt
At least a portion of cooling water hole is located at one end of the close quick-detachment flange shaft of roll shaft, and runs through diametrically whole roll shaft.
Advantage and good effect that this patent has are:
Because this patent adopts technique scheme, directly quick-detachment flange shaft is docked with roll shaft, and realize and coordinate and locate with the outer circumference surface of roll shaft end by depression rim of the mouth, adopt that accuracy of alignment is high in this way, be conducive to the stable of roll squeezer, and avoided expansion set to be directly installed on roll shafts of roll press and cause cannot be for convenience detach problem.In addition, cooling water hole is set to through hole, also helps raising crudy.
