    1489289 Twin-screw extruder drive PLAST-UND ELASTVERARBEITUNGSMASCHINEN - KOMBINAT KARL - MARX STADT VEB 22 May 1975 [18 June 1974] 22308/75 Heading B5A [Also in Division F2] In a torque-dividing gear transmission, which may be used to drive a screw shaft of a doublescrew extruder, a driving pinion 2 secured to an input shaft 1 on a fixed axis in a gear-box 20 is meshed bilaterally with two idler wheels 7 and 9, which each mesh with another idler wheel 13, 11, respectively, and an output shaft 14, also on a fixed axis in gear-box 20, carries a pinion 15, meshed bilaterally with the two idler wheels 13 and 11, so that partial torques are transmitted to the output shaft 14 through the parallel paths formed by the two pairs of idler wheels 7, 13 and 9, 11 respectively. In one embodiment the four idler wheels 7, 9, 13 and 11 having shafts 6, 8, 12, 10, are together carried by a movable rocker frame 5, Fig. 3, which is retained in a floating relationship to the gear-box 20 by struts 24 with hinge joints 22, 23. In another embodiment, Fig. 2 (not shown), a similar rocker frame 5 is retained in a floating relationship by parallel guideways (21) in the walls of gear-box 20. In use, the frame 5 becomes subjected to reaction forces derived from the circumferential forces present at each point where idler wheels and pinions intermesh, whereby a self-adjusting displacement of frame 5 occurs, until the partial torques in the two paths become equalized. In an alternative embodiment, Fig. 1, idler wheels 9, 11 are carried on a rocker arm 3, and wheels 7, 13 are carried on a separate rocker arm 4, with arm 3 together with shaft 8 being rotatable about one fixed axis in gear-box 20, and arm 4 together with shaft 12 being rotatable about another fixed axis, while arms 3 and 4 are linked together by a strut 18 having an adjustment member 19 and hinge joints 17. In use, arm 3 is subjected to reaction forces derived from circumferential tooth forces acting on wheel 11, and arm 4 to reaction forces related to wheel 7, whereby a joint self-adjusting displacement of the arms 3 and 4 occurs, until the partial torques become equalized. The balanced nature of the output drive torque avoids asymmetric radial loading of the shaft 14, thus permitting a compact assembly in which the bearings of shafts 1 and 14 may be of small dimensions, and a second independent output shaft 16 may be located close to shaft 14, e.g. for driving a second screw shaft in a double-screw extruder.

    The invention relates to mechanical engineering, namely to the design of gears for an extruder with a double screw.
    Of the known devices of a similar purpose 5, the closest in their technical essence to this invention is a gear train comprising a housing, drive and driven shafts with gears, two flows of paired drive gears and a load balancing mechanism associated with spurious gears by means of the G1 axes )
    This gear transmission is quite and widely used, however, due to the imperfection of the load balancing mechanism between flows, its operational reliability is low.
    The aim of the invention is to increase the operational reliability of transmission.
    This goal is achieved due to the fact that the load balancing mechanism is made in the form of an H-shaped cage having the ability to move in the plane of the wheels, in the parallel parts of which the spurious gear axles are arranged in pairs. The parallel parts of the H-ring are pivotally connected to the part connecting them, and the axis of the spurious wheels, respectively, of one stream coupled to the driving gear and another stream coupled to the driven gear are fixed in the housing. The H-shaped clip can be made in the form of a single element, and parallel guides are made in the housing, restricting the movement of the clip in a plane parallel to the parallel parts of the clip.
    The guides can also be made in the form of rods pivotally connected to the housing and to one of the parallel parts of the cage.
    In FIG. 1 shows a kinematic transmission scheme in which the parallel parts of an H-shaped clip are pivotally connected to a part connecting them; in FIG. 2 the same, but with the implementation of the H-shaped cage in the form of one element and using parallel guides in the housing, · in FIG. 3 - the same, but with guides made in the form of rods,
    The gear train for the extruder with a double screw contains a housing 1, a drive shaft 2 with a gear wheel 3, an old shaft 4 with a gear wheel 5, two spurious gear flows, one of which includes gears 6 and 7, and the other gears wheels 8 and 9 and a load balancing mechanism made in the form of an N-shaped cage, in the parallel parts of which axles 10, 11 and 12, 13 of spurious gears 7-9 are placed.
    In one of the constructive variants of the transfer 20, the parallel parts of the H-shaped cage are made in the form of wings 14 and 15, connected to the connecting part of the rod 16, equipped with a coupling nut 17, with the help of hinges 18, and 25 of the axle 10 and 13 of the spurious wheels 7 and 9 fixed in the case.
    The H-shaped clip can also be made in the form of one element 19, and the housing 1 is made with parallel 30 guides 20, restricting the movement of the clip in a plane parallel to the parallel parts of the clip 19. Instead of parallel guides made in the housing, guides can be used 35 in the form of rods 21 pivotally, with the help of hinges 22, connected with the housing 1 and with the help of hinges 23 - with one of the parallel parts of the H-shaped clip. 40
    The transfer works as follows. From the gear wheel 3 of the drive shaft, the torque is transmitted to the spurious gears 45 6 and 7 located on the two-sided gearing with the gear 3. Partial torques are transmitted from these spurious gears to the next spurious gears 50 located on the two-sided gears 5 8 and 9 and further to the driven screw shaft 4. In this case, the tangential forces that appear when the torque is transmitted appear on the gears 6–9 and are transmitted in one embodiment through the axles 12, 10, 11 and 55 13 and the hinges 18 with a thrust of 16, all of a sudden Ohm option - through the guides 20, and in the third option - through the hinged rods 21 to the housing 1, due to the reactions that have arisen in the above elements, the load is evenly distributed between them.
    Thus, thanks to the indicated constructive solution of the load balancing mechanism, it was possible, firstly, to organize the transfer of large capacities without increasing the dimensions of the transmission, and secondly, to significantly increase its operational reliability.
