Description
Technical field
The present invention relates to gear-box more particularly to extruder gearbox belt wheel load removing devices.
Background technique
There are two types of forms for parallel dual-screw extruding machine gear-box, and one is slow down and power distribution integration, i.e. four-axle type-
The gear deceleration, another kind are external deceleration/internal powers point, i.e. triple axle-belt pulley slows down.Although the latter's appearance and performance are slightly
It is inferior, but manufacturing cost is low, there is certain occupation rate of market.
Currently, most of belt wheel reduction gear boxes, belt pulley are directly installed on main shaft left end.As shown in Figure 1, the prior art
In belt pulley reduction gear box, wherein 15 be tapered sleeve, 16 be key, and 17 be gland, and 15 inner hole of tapered sleeve has cut keyway, passed through key 16
Rotation is connected with main shaft 1；6 left end screw of belt wheel is simultaneously next, and tapered sleeve 15 is tightly combined together belt wheel 6 and main shaft 1.It is left
Side pressure lid 17 prevents belt wheel 6 from disengaging main shaft 1.Wherein, belt pulley is directly installed on main shaft left end, and main shaft will not only transmit torque,
And belt pulley own wt and belt tension are born, complicated alternate stress effect, so that main shaft failure rate is very high.
Summary of the invention
Goal of the invention: aiming at the problems existing in the prior art with deficiency, the present invention provides a kind of extruder belt pulley and unloads
Lotus device, belt pulley weight and belt tension are undertaken by pivot flange, and main shaft is used only to transmitting torque, and greatly improving main shaft makes
Use the service life.
Technical solution: extruder gearbox belt wheel load removing device, the pivot flange component including empty set on main shaft；Support
Flange assembly include left flange, bearing, spacer ring, right flange, driving spindle rotation belt pulley, and be mounted on cabinet side
Pivot flange；Left flange, bearing, spacer ring, right flange and belt pulley are mounted on pivot flange in groups, and belt pulley is pacified by bearing
On pivot flange.
Pulley side end face is fixed with driving flange, and driving flange is connect with main shaft by tensioner, and belt pulley passes through
Tensioner driving spindle.
The utility model has the advantages that belt pulley in the prior art is directly installed on main shaft left end, main shaft will not only transmit torque, but also
Bear belt pulley own wt and belt tension, complicated alternate stress effect, so that main shaft failure rate is very high；And this hair
Bright belt pulley relief arrangement, belt pulley weight and belt tension are undertaken by pivot flange, and main shaft is used only to transmitting torque, are improved
Structure afterwards, Main Shaft Service Life are extended.
Detailed description of the invention
Fig. 1 is prior-art devices figure；
Fig. 2 is extruder gearbox belt wheel load removing device figure of the present invention；
Fig. 3 is relief arrangement partial enlarged view.
Specific embodiment
As shown in Figure 2 and Figure 3, in inventive belt wheel relief arrangement, 1 is main shaft, and 2 be gear box of double-screw extruder case
Body, 3 be spindle flange, and 4 be pivot flange, and 5 be right flange, and 6 be belt pulley, and 7 be bearing, and 8 be spacer ring, and 9 be left flange, and 10 are
Tensioner, 11 be driving flange, and 12 be positioning surface A, and 13 be positioning surface B, and 14 be positioning surface C.Wherein extruder gearbox main shaft 1
It by spindle flange 3, is fixed on gear housing 2, certain length is stretched out in 1 left end of main shaft.
Relief arrangement includes left flange 9, bearing 7, spacer ring 8, right flange 5, belt pulley 6, this part is mounted in groups
On pivot flange 4.The belt pulley 6 being mounted on pivot flange 4 by bearing 7 easily rotates.
Be mounted with that the pivot flange component empty set of belt pulley 6 in 1 left end of main shaft, is mounted on 2 left side concave station of cabinet, i.e., it is fixed
Plane B 13, blending bolt is fixed.
Installation driving flange 11 is fixed by bolts to the left side of belt pulley 6, driving flange 11 and the tensioner 10 of main shaft 1
Connection.Belt pulley 6 passes through 10 driving spindle 1 of tensioner.
6 weight of belt pulley and belt tension are undertaken by pivot flange 4, this fractional load is passed to gear by pivot flange 4
Cabinet 2, main shaft 1 are used only to transmitting torque, greatly improve Main Shaft Service Life.
To guarantee 6 running accuracy of belt pulley, the bearing installation positioning surface A 12 of pivot flange 4 must be right with pivot flange 4
End outer circle has good concentricity, and 4 right end faying face of pivot flange must have good verticality；The supporting methods of gear housing 2
Blue 4 mounting holes-positioning surface B 13 must have good concentricity with the positioning surface C14 of main shaft bearing mounting hole.
The single-screw extruder gearbox that the invention patent slows down for belt wheel, the belt wheel twin-screw of another form
The transmission main shaft of extruder gearbox, i.e. installation belt pulley drives short output shaft and long output shaft simultaneously, equally there is directive significance.
