Abstract
The utility model discloses a long shaft output shaft structure of a three-shaft transmission system of an equidirectional parallel double-screw extrusion machine, comprising a shaft body, wherein the front end of the shaft body is connected with a screw rod core shaft, the tail end of the shaft body is connected with the front end of a shaft head gear wheel which is engaged with a first driven gear on an auxiliary shaft; a second driven gear is arranged at the tail end of the shaft head gear wheel and is engaged with a first driving gear wheel on an input shaft. In the utility model, a shaft body and the shaft head gear wheel of a long shaft output shaft are respectively manufactured, the processing difficulty is reduced, the processing precision is increased, according to the stress requirements of the shaft body and the shaft head gear wheel, different heat treatment technologies are adopted, and the service life of the long shaft output shaft is prolonged, after gear wheels of a transmission box are all mounted in place, when phase adjustment is carried out to two output shafts, the shaft body of the long shaft output shaft is only needed to be pulled out from the shaft head gear wheel, and the shaft body is rotated to adjust the phase, the other output shaft is not needed to be lifted, and the phase adjustment is fast, and labor and time saving.
Description
Technical field
The utility model relates to a kind of transmission shaft structure, especially a kind of major axis output shaft structure of cocurrent and parallel double screw extruder three shaft transmission systems.
Background technique
In three shaft transmission systems of the cocurrent and parallel double screw extruder transmission case that uses both at home and abroad at present, the power that motor passes to input shaft reaches first output shaft (major axis) through gear pair, is responsible for 50% power output by first output shaft; First output shaft reaches auxiliary axis through gear pair with remaining power simultaneously, and auxiliary axis reaches second output shaft (minor axis) through gear pair again, is carried out the power output of residue 50% by second output shaft.
Because the structure particularity of cocurrent and parallel double screw extruder transmission case, first output shaft is a major axis, and second output shaft is a minor axis.Existing first output shaft (major axis) all is the integrated design with gear, owing to need process incorporate gear and axle simultaneously, the difficulty of processing of first output shaft is big; Because the heat treatment process requirement of gear and axle is different, incorporate gear can increase heat treatment difficulty and cost with axle, also can influence the working life of gear and axle in addition.Simultaneously, since first output shaft and second output shaft in the same way the synchronous high-speed rotation to guarantee the mutual noninterference mutually that is in operation of two screw rods; Therefore, when assembling first output shaft and second output shaft, require first output shaft and the second output shaft phase place are adjusted into 90 °.In adjustment during phase place, need second output shaft be lifted the back and move a tooth and put down the inspection phase place again, and then repeat above-mentioned action, be adjusted into 90 ° until the phase place of confirming first output shaft and second output shaft, very inconvenient with take a lot of work, time-consuming, effort.
Summary of the invention
Goal of the invention: the purpose of the utility model is to solve the problems of the technologies described above, and provides a kind of and is convenient to process, the major axis output shaft structure of cocurrent and parallel double screw extruder three shaft transmission systems of long service life, phase place adjustment simple and fast.
In order to solve the problems of the technologies described above, the utility model has adopted following technological scheme:
A kind of major axis output shaft structure of cocurrent and parallel double screw extruder three shaft transmission systems; Comprise axis body; The front end connecting screw rod mandrel of said axis body, the tail end of axis body connects the front end of shaft head gear, a driven gear engagement on said shaft head gear and the auxiliary axis; The tail end of shaft head gear is provided with driven gear No. two, a driving gear engagement on said No. two driven gears and the input shaft.
Wherein, the front end of said axis body is that spline is connected with screw mandrel.
Wherein, the tail end of said axis body is that spline is connected with the front end of shaft head gear.
Wherein, the tail end of said shaft head gear is that flat key is connected with No. two driven gears.
Beneficial effect: the utility model is made the axis body and the shaft head gear of major axis output shaft respectively, has reduced difficulty of processing, and has improved machining accuracy; According to axis body and shaft head gear force request, adopt different heat treatment process, improved the working life of major axis output shaft; After the gear of transmission case all is in place, when carrying out the phase place adjustment of two output shafts, only need the axis body of major axis output shaft is extracted from shaft head gear; Rotation shaft adjustment phase place gets final product; Need an other output shaft not lifted, the adjustment phase place quick, the saving of labor, save time, laborsaving.

Embodiment:
Below in conjunction with accompanying drawing the utility model is done explanation further.
As illustrated in fig. 1 and 2; The major axis output shaft structure of a kind of cocurrent and parallel double screw extruder three shaft transmission systems of the utility model; Comprise axis body 1; The front end connecting screw rod mandrel of said axis body 1, the tail end of axis body 1 connects the front end of shaft head gear 2, a driven gear 4 engagements on said shaft head gear 2 and the auxiliary axis 3; The tail end of shaft head gear 2 is provided with driven gear 5 No. two, a driving gear 7 engagements on said No. two driven gears 5 and the input shaft 6.Input shaft 6 drives the rotation of shaft head gear 2 and axis body 1 through a driving gear 7 and No. two driven gears 5; Shaft head gear 2 drives auxiliary axis 3 and rotates through a driven gear 4, and auxiliary axis 3 drives the rotation of minor axis output shaft through No. two driving gears 8 and No. three driven gears 9.
Shown in Fig. 3 to 8, require the two ends of axis body 1 all are designed to external splines according to transmission, the front end of shaft head gear 2 is made into internal spline, and the tail end of shaft head gear 2 is manufactured with the flat key groove.The external splines of axis body 1 front end matches with the spline of screw mandrel, and the spline of axis body 1 tail end matches with the internal spline of shaft head gear 2 front ends, and the tail end of shaft head gear 2 is connected with driven gear 5 through flat key.
For the intensity of axis body 1, shaft head gear 2 and No. two driven gears 5, warp is theoretical and facts have proved it is can reach the transmission requirement fully.
