Description
Technical Field
The utility model relates to a kneading machine technical field specifically is a horizontal continuous screw rod extrudes type kneading machine shaft connecting structure.
Background
In the material production process, common double screw extruder is horizontal structure, the dabber of screw rod needs to drive through motor and speed reducer, all adopt the shaft coupling to accomplish at present between the dabber of output shaft of speed reducer and screw rod, because the dabber of screw rod is less with speed reducer output shaft interval, the moment of torsion of transmission is little when current shaft coupling adopts the parallel key, and use holding screw to prop up the parallel key, there is the risk of axial play in the use, the parallel key rigidity during the installation, need aim at and just can realize the installation, the assembly degree of difficulty has been improved.
Disclosure of Invention
In order to solve the problem that the transmission torque is little, the installation is difficult, have axial to move the risk of shaft coupling connection, the utility model provides a horizontal continuous screw rod extrudes type kneader and uses shaft connecting structure, its simple to operate can not have the axial to move the phenomenon and take place and can transmit big moment of torsion.
The technical scheme is as follows: the shaft connecting structure for the horizontal continuous screw extrusion kneader comprises an output shaft of a speed reducer and a mandrel of a screw which are coaxially arranged, and is characterized in that the output shaft of the speed reducer and the mandrel end of the screw extend into the same connecting sleeve, an internal spline and external spline matching structure is arranged between the inner wall of the connecting sleeve and the outer peripheral surface of the output shaft of the speed reducer and between the inner wall of the connecting sleeve and the outer peripheral surface of the mandrel of the screw, hough sections which are abutted against two end faces of the connecting sleeve are arranged on the output shaft of the speed reducer and the mandrel of the screw, and a locking cover which is in threaded connection with the end part of the connecting sleeve is arranged outside the hough sections.
The screw rod adjusting device is further characterized in that an adjusting base plate is arranged between an output shaft of the speed reducer and a core shaft of the screw rod, and the adjusting base plate is fixed on the end face of the output shaft of the speed reducer or the end face of the core shaft of the screw rod through a bolt;
the outer peripheral surfaces of two ends of the connecting sleeve are small-diameter sections, and external threads are arranged on the outer peripheral surfaces of the small-diameter sections;
and a through hole with the size larger than or equal to the output shaft of the speed reducer or the core shaft of the screw is formed in the middle of the locking cover.
Adopt the utility model discloses afterwards, the flat key structure that will be original has changed inside and outside spline fit structure, and spline transmission moment of torsion is far greater than the flat key under the same shaft diameter, and the adapter sleeve both ends have hough festival and locking lid, can effectively guarantee the reliable and stable nature of connection, can not take place to move to the spline can be adjusted on the circumferencial direction when the installation, can rotate and confirm suitable installation angle, has reduced the installation degree of difficulty.

fig. 2 is an enlarged schematic view of a point a in fig. 1.
Detailed Description
Referring to fig. 1 and fig. 2, a shaft connecting structure for a horizontal continuous screw extrusion kneader comprises an output shaft 1 of a speed reducer and a mandrel 2 of a screw, which are coaxially arranged, wherein the end parts of the output shaft 1 of the speed reducer and the mandrel 2 of the screw extend into the same connecting sleeve 3, in order to reduce the processing difficulty, an adjusting shim plate 4 can be arranged between the output shaft 1 of the speed reducer and the mandrel 2 of the screw, the adjusting shim plate 4 is fixed on the end surface of the output shaft 1 of the speed reducer or the end surface of the mandrel 2 of the screw through a bolt 5, in this embodiment, the adjusting shim plate 4 is fixed on the end surface of the mandrel 2 of the screw, when the size of the connecting sleeve 3 is deviated, the adjusting shim plate 4 can be used for adjustment, so as to ensure that the output shaft 1 of the speed reducer and the mandrel 2 of the screw are tightly pressed in the connecting sleeve 3, and an inner spline and outer, the inner wall of the connecting sleeve 3 is an internal spline, the outer peripheral surface of an output shaft 1 of the speed reducer and the outer peripheral surface of a core shaft 2 of the screw are external splines, the output shaft 1 of the speed reducer and the core shaft 2 of the screw are provided with half sections 6 which are abutted against the two end surfaces of the connecting sleeve 3, and the outside of each half section 6 is provided with a locking cover 7 in threaded connection with the end part of the connecting sleeve 4. The outer peripheral surfaces of two ends of the connecting sleeve 3 are small-diameter sections, external threads are arranged on the outer peripheral surfaces of the small-diameter sections, and the locking cover 7 just abuts against the step surface when being screwed tightly. The through-hole of output shaft 1 or the dabber 2 of screw rod that size more than or equal to the speed reducer is seted up to the middle of locking lid 7, is greater than in this embodiment, and it is more convenient to operate.
