Between the output shaft 10 and the faceplate 13 is installed shims 17 and the bearing 18. Faceplate 13 is mounted on the output shaft through the washer 19 by bolts 20.
Rotation device of the manipulator harvesting machine operates as follows.
The statement includes a rotation mechanism 5 turntable 4. When the output shaft 10 with the pinion 11 is forced to rotate around its vertical axis and rotating in bearings 18 and 21, the teeth of the pinion 1 will be our teams on the toothed crown 12 of the fixed part 1. The upper movable part 3 together with the turntable 4 rotates in a horizontal plane on the rolling elements 6, and the face-plate 13 with the bracket 14, the driven output shaft 10, will make a rotation around the vertical axis of the output shaft 10 and gear 12. If this is th 1 are interconnected through the faceplate 13, the brackets 14 and the tapered rollers 16, are practically eliminated the console output shaft 10 and the bias in the engagement of the teeth of the driving gear 11 and the ring gear 12.
In the process of installation and operation can be adjusted clearance in the engagement of the driving gear 11 and the gear 12 by the movement of the rotation mechanism 5 on the rotary platform 4 and the diminution or addition of a number of shims 17, thereby raising or lowering, respectively, the tapered rollers 16.
In such a constructive implementation of a turntable manipulator forest machines virtually eliminated the bias in the engagement of the teeth of the driving gear 11 and the ring gear 12, which eliminates the bummer and chipping of the teeth and improves the reliability and durability of the device.
