Summary of the invention
The purpose of this utility model is: at the radial clearance of present single screw extrusion machine with the inside of the rolling bearing of the existence of the output mechanism in the main gear reducer itself; gap that box body hole cooperates with bearing outer ring and the speed reducer casing error when processing and speed reducer assembling; the position degree of speed reducer output shaft and seam are beated and are difficult to reach technical requirement on design; and the hollow shaft axial float is big; break the single screw extrusion machine pin easily; and hollow output shaft internal spline processing difficulties and heat treatment cost are high and the spherical roller thrust-bearing is lower than lubricated pasta; it is not smooth lubricating oil return to occur through regular meeting; leak into problems such as single screw extrusion machine inside, provide a kind of new single screw extrusion machine with the output mechanism in the main gear reducer.
The purpose of this utility model is achieved in that the output mechanism of a kind of single screw extrusion machine in the main gear reducer, comprise hollow output shaft, be installed in the deceleration gearwheel on the hollow output shaft, geared sleeve, the spherical roller thrust-bearing, selfaligning roller bearing, positioning bearing and casing, wherein: the hollow output shaft that the deceleration gearwheel is installed is passed through selfaligning roller bearing, bearing support and positioning bearing are installed on casing, on the spherical roller thrust-bearing is located in the bearing support of hollow output shaft output terminal, it is characterized in that: the hollow output shaft output terminal is connected with geared sleeve, is furnished with seal ring in the bearing support of hollow output shaft output terminal; Set up single direction thrust ball bearing and spring at the selfaligning roller bearing end; The adjustment ring is set respectively in the positioning bearing both sides and compresses round nut.
In the utility model: the hollow output shaft output terminal is for the hollow shaft of internal spline, and with being provided with spline housing in the hollow shaft of internal spline, the hollow output shaft output terminal is not connected with geared sleeve.
In the utility model: be provided with gear pump on casing, the oil absorbing end of gear pump is connected by the bearing support of the hollow output shaft output terminal in oil pipe and the output mechanism, and the oil impregnate that infiltrates bearing support returns in the casing by gear pump.
In the utility model: the line shaft of gear pump is connected with prime gear shaft in the speed reducer.
Advantage of the present utility model is: traditional hollow output shaft is divided into spline housing, seal ring and not with the hollow shaft of internal spline, realizes processing respectively the mode of assembly unit again, saved greatly because of processing and heat treatment bring expensive; Owing to set up single direction thrust ball bearing and spring at the selfaligning roller bearing end, spherical roller thrust bearing is carried out pretension, utilize it from the centering characteristic, reduce the inner radial gap of bearing and the gap that bearing cooperates with casing simultaneously, improved Location accuracy; The adjustment ring is set respectively in the positioning bearing both sides and compresses round nut, not only improved the position degree of speed reducer output shaft, and avoided or reduced the axial float of hollow shaft, avoid breaking the single screw extrusion machine pin; Owing on casing, be provided with gear pump, in bearing support, be furnished with seal ring simultaneously, although the spherical roller thrust-bearing is lower than lubricated pasta, return in the casing by gear pump for the oil impregnate that may occur, avoid oil impregnate to leak into single screw extrusion machine inside.
