The utility model adopting the structure has the advantages that the obstruction to material flow can be avoided, and the material conveying efficiency can be improved; the disassembly is convenient, the maintenance is easy, and the good working performance of the screw conveyor can be ensured when the intermediate connecting device is arranged on the screw conveyor with the diameter more than one meter.
Description
Technical field
The utility model relates to conveyor screw, especially relates to the middle connecting device of conveyor screw.
Background technology
At present, conveyor screw has a plurality of conveyor screws that are coupled to each other, a flange is respectively welded at each spirochetal screw shaft two ends, all be processed with a plurality of uniform Bolt Connection holes on each flange, a plurality of conveyor screws are connected into one mutually by bolt, in conveyor screw when work,, conveyor screw rotates and promotes material and axially move ahead along helical surface, and material is transported to the other end from an end of conveyor screw.Because the external diameter of the flange of screw shaft end has hindered Flow of Goods and Materials much larger than the external diameter of screw shaft, cause mass transport efficient to reduce, simultaneously the conveyor screw maintenance difficult of this structure.When the diameter of conveyor screw greater than 1 meter, because of operational throughput is bigger, conveyor screw requires transfer torque big, the cross-sectional plane of the spirochetal connecting flange of the conveyor screw of existing structure will be bigger, causes the conveyor screw can't normal operation.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of conveyor screw middle connecting device, connecting device can improve mass transport efficient in the middle of this conveyor screw, be convenient to maintenance, be installed on diameter greater than guaranteeing on 1 meter the conveyor screw that the conveyor screw serviceability is good.
Solve this technical problem, the technical solution of the utility model is: connecting device in the middle of a kind of conveyor screw, coupling spindle in the middle of it comprises, middle coupling spindle two ends respectively with the affixed spindle nose of two adjacent screw shafts, arc key and axle sleeve, coupling spindle is by forming with the coupling spindle junction surface of suspender member bonded assembly coupling spindle support and coupling spindle support two ends symmetry in the middle of described, the cross-sectional plane of described spindle nose is identical with the cross-sectional plane at coupling spindle junction surface, be the circle with the arc notch that adapts with described arc key, described axle sleeve is fixedly sleeved in coupling spindle junction surface and spindle nose place.
The cross-sectional plane at the cross-sectional plane of described spindle nose and coupling spindle junction surface is the circle of the arc notch that adapts with arc key with two symmetries.
Described suspender member comprises the U-shaped screw rod and is placed in the bearing seat of coupling spindle support.
Described bearing seat and coupling spindle support are free-running fit, and the gap between described bearing seat and the coupling spindle support is 1～2 millimeter.
The utility model adopts the middle connecting device of the conveyor screw of this spline structure, and compared with prior art, the axle sleeve of the maximum gauge only diameter than screw shaft is big slightly, has avoided the obstruction Flow of Goods and Materials, has improved mass transport efficient.Simple in structure, the convenient disassembly of the utility model is convenient to maintenance, is installed on diameter greater than guaranteeing on one meter the conveyor screw that the conveyor screw serviceability is good.
