    A transmission for two driven shafts which are parallel to and at a small spacing from one another and which drive the twin screws of the extruder wherein each shaft has a respective driven pinion thereon with the two pinions axially displaced with respect to one another and for each pinion there is a respective drive each comprising three intermediate gears equiangularly disposed around the pinion and meshed therewith, a ring gear surrounding and meshed with the three intermediate gears and drive means to rotate the ring gear, the pinion and two of the three intermediate gears not having any mountings, i.e. floating, and the third intermediate gear being free to move in directions radially of the pinion thereby to obtain equal division of drive power between the three intermediate gears and avoid forces tending to move the pinion radially.

    The invention relates to mechanical engineering, in particular to gears for twin screw extruders.
    A known twin-screw extruder drive comprising a housing, two parallel driven shafts installed in it, each of which has a gear system consisting of a driven gear mounted on a corresponding driven shaft, a central gear with internal teeth placed on bearings in the housing, and intermediate gears', evenly spaced three around the circumference and meshed with the driven and central gears, and the gear system one relative to each other axially offset, intermediate toothed wheels have shafts, rotating at the fixed rigid supports £ 1].
    The disadvantage of the drive is the uneven distribution of the load between the gears.
    The purpose of the invention is to increase the uniformity of the load distribution by gears.
    This goal is achieved by gem, in the drive of a twin-screw extruder containing a housing, two parallel driven shafts installed in it, each of which has a gear system consisting of a driven gear 10 of a fixed wheel mounted on the corresponding driven shaft, a central gear with internal teeth placed on the supports in the housing, and the intermediate gears installed, 15 uniformly in three circumferences and engaged with the driven and central gears, and the gear systems x wheels relative to one another axially are offset in each system but od20 of intermediate gears housed in the housing with the possibility of radial displacement toward the axis. shaft, and the other two are free.
    In FIG. 1 shows the kinematic diagram of the drive (only one system is shown3, the design of only one gear system is described below, since the other is identical to the first); in FIG. 2 same, top view.
    The drive contains driven shafts 1 and 2, 5 parallel to each other. A system of gears is located on each shaft, each of which is mixed relative to the other in the axial direction.
    One driven gear wheel 3 is installed on each driven shaft. The central gears 4 and 5 have internal teeth and are mounted coaxially to the shafts 1 and 2 in the plane of their system. and
    The intermediate gears 6-8 are engaged with the respective driven and central wheels. Moreover, the wheel 6 mounted on the support 9 of the axis, having at the ends of the flat sections located in the fork 10 of the bracket 11, mounted in the housing 12 of the drive, has the possibility of radial displacement.
    Two other intermediate gears 7 and 8 do not have bearing bearings and axles. Their freedom of movement is limited by two-sided gearing.
    The central wheels 4 and 5 are installed in the housing on the supports 13 and 14. Each of the wheels 4 and 5 has external teeth 15 and 16, which are engaged with the drive wheel 17.
    When the drive has a working load, the intermediate gears 6-8 and the corresponding driven gear 3 are adjusted so that the three gears transmitting rotation are uniformly loaded. The output torque transmitted to the driven shafts 1 or 2 is distributed evenly to these gears. The uniform distribution of power allows you to transfer a large moment of rotation to parallel, adjacent to each other, driven shafts of the twin extruder screws, and will reduce the cost of manufacturing the drive.

    the topic below describes the design of only one gear wheel system, since the other is identical to the first one; in fig. 2 the same, top view. The drive contains driven shafts I and 2 parallel 4 th each other. A gear system is located on each shaft, each of them being shifted relatively differently in the axial direction. Each driven shaft is fitted with one driven gear wheel 3, the central gear wheels 4 and 5 have internal teeth and are mounted coaxially with shafts I and 2, each in the plane of their system. Intermediate gears 6-8 are meshed with corresponding pulleys and central wheels. Moreover, the wheel 6 mounted on an axle support 9, having flat ends at the ends, placed in a fork of U crown of Tein II, fixed in the drive housing 12, has the possibility of radial displacement. Two other intermediate gear wheels 7 and 8 do not have bearing supports and axles. Freedom of movement is limited by double-sided gearing. The central wheels 4 and 5 are mounted in the housing on supports 13 and 14. Each of the wheels 4 and 5 also has external teeth 15 and 16, which engage with the drive wheel 17. When the drive is loaded, the intermediate gear wheels 6-8 and the corresponding driven gear the gear wheel 3 is adjusted so that the three gear wheels, which transmit the rotation, are uniformly loaded. The output torque transmitted to the driven shafts I or 2 is evenly distributed to these gears. A uniform power distribution allows a large torque to be transferred to parallel, adjacent to each other, driven by a small distance, the driven shaft1, 1 of the twin extruder screws, and reduces the cost of manufacturing the drive. DETAILED DESCRIPTION OF THE INVENTION A twin-screw extruder drive comprising a casing, two parallel driven shafts mounted therein, each of which has a gear system, consisting of a sprocket-gear mounted on a respective spindle, a central gear wheel with internal teeth on the supports in the housing, and the intermediate gears, installed evenly in a circle around the circumference and engaging with the driven and central gears, and the system of gears one relation itelno other axially offset, characterized in that, in order to increase the uniformity of load distribution between the toothed wheels, in each system, one of the intermediate gears housed in the housing with the possibility of radial displacement to the shaft axis, and the other two - free.
