SYSTEM OF A SCREW-TYPE TRANSMISSION OF A MULTI-SCREW EXTRUDER OR A MIXER Russian patent published in 2020 - IPC B29C48/40 B29B7/46 B29B7/80 F16H37/06 

FIELD: machine building.

SUBSTANCE: group of inventions relates to a system of gearing of a multi-screw extruder distributing loads, applied to driven shafts without complicating the configuration of the device (versions). System of the screw-type transmission of the multi-screw extruder or mixer has multiple augers, contains a drive shaft on which the driving gear wheel is fixed and which is driven into rotation by the drive device. At that, the driven shaft on which the driven gear wheel is fixed is engaged with the driving gear wheel. Driven shaft is connected with screw to drive screw, and shaft of load distribution, on which load distributing gear is fixed, is engaged with driven gear wheel. Note here that load distribution shaft is located in the area opposite driven driven shaft relative to driven shaft. Radial load generated on the driven shaft is transmitted via the driven gear and the gear wheel distributing the load to the load distribution shaft for load distribution.

EFFECT: technical result achieved when using a group of inventions is to reduce the size of bearings or width of teeth for miniaturization of the configuration of the system.
