The model utility content
The purpose of this utility model is to provide a kind of and meshes smooth and easy, that noise is low, vibration is little, moment of torsion is high flat in the same way two extruder middling speed height and turn round gear-box.
The technological scheme that realizes the utility model purpose is: a kind of flat in the same way two extruder middling speed height are turned round gear-box, have casing, and casing is provided with input shaft, output A axle and output B axle; Also be provided with jack shaft and two transition axises in the casing, input shaft is provided with the input gear, jack shaft is provided with first center tooth and second center tooth, output A axle is provided with first output gear and the 3rd center tooth, and output B axle is provided with second output gear, and transition axis is provided with the 4th center tooth and the 5th center tooth, input gear and the engagement of first center tooth, second center tooth and the engagement of first output gear, the 3rd center tooth and the engagement of the 4th center tooth, the 5th center tooth and the engagement of second output gear.
Two transition axises that above-mentioned flat in the same way two extruder middling speed height are turned round gear-box be arranged in parallel, two the 4th center tooth and the engagement of the 3rd center tooth, two the 5th center tooth and the engagement of second output gear.
Each gear that above-mentioned flat in the same way two extruder middling speed height are turned round gear-box all adopts the displacement helical gear.
The casing that above-mentioned flat in the same way two extruder middling speed height are turned round gear-box is the last nowel split part with mounting hole that split casting forms.
The utlity model has following characteristics: the power dividing type design is adopted in (1) the utility model B shaft drive, promptly mesh transmitting torque simultaneously by gear and B axle by two transition axises, thereby make the B shaftgear have two teeth stressed simultaneously, and stressedly have only original single jack shaft to transmit half of power, make the moment of torsion of B axle transmission double, the bearing capacity of complete machine improves 50%, and safety factor improves 30%, can satisfy the requirement of present double screw extruder to the high rotating speed high reliability of the high moment of torsion of gear-box; (2) each gear of the utility model all adopts the displacement helical gear, has guaranteed gear under the prerequisite of high bearing capacity, meshes that smooth and easy, noise reduces, the bearing capacity height; (3) casing of the present utility model is that last nowel divided casting forms, and has good seismic resistance and load-carrying properties.
