The invention concerns a device for maintaining the relative phase shift between an endless conveyor and a rotary or rotatingly indexing table and/or additional conveyors attached thereto, wherein the endless conveyor has a fixedly journalled drive wheel and a displaceably journalled tensioning wheel, process tools e.g. holders, jaws and similar fixtures being attached to the conveyor at equal spacing along its length and being associated with the rotary or indexing tables and/or additional conveyors elements driven synchronously, by means of a common drive, with the conveyor, the drive shafts of the table(s) and/or additional conveyors being linked by a shaft coupling, consisting of an axially fixed sleeve and an axially movable sleeve, the sleeves having complementary helicoidal bearing surfaces with a predetermined pitch of thread, and a transmission, a predetermined transmission ratio connecting the displaceably guided bearing of the sprocket wheel and the axially movable sleeves of the shaft coupling.
A device for maintaining the relative phase shift between an endless conveying element and at least one rotary work table comprising at least one fixedly journalled drive wheel, a tensioning wheel, and a resiliently loaded, displaceable and guided bearing for the tensioning wheel for the endless conveying element, process tools attached to said endless conveying element at equal spacing along its length, means for driving said at least one rotary table synchronously with the said endless conveying element, the drive means including a drive shaft for the said at least one rotary table, at least one shaft coupling for said drive shaft consisting of an axially fixed sleeve and an axially movable sleeve, complementary helicoidal bearing surfaces with a predetermined pitch of thread on said fixed and movable sleeves, and a transmission with a predetermined transmission ratio connecting the displaceably guided bearing of the tensioning wheel and the axially movable sleeve of the shaft coupling.
