3.6 WORM DRIVE
Worm driving force is transmitted from tractor by means of telescopic-joint shaft (1) that
connects feed car with tractor, telescopic-joint shaft (2) with built in overload friction clutch for
planetary reduction gear (3). Worm (4) rests on back-end shaft. Feed car is designed to work
with power take-off rotational speed not bigger than 540 rpm. Two adjustable cutting blades
are attached to worm disk. Worm rotates clockwise (when looking at the feed car from
above).
Components of feeding stuff are administered to the tank from above. Worm drive is turned
on at that time. Foodstuff drop down and are collected by worm by surface (A) and moved
up. Then, when running along walls, fall off again. At that time foodstuff is milled with use of
cutting blades (6) installed on the worm and milling blades (7) installed on walls of the tank.
Figure (3.8A) shows worm driving gear, circulation of foodstuff during mixing and milling
process – arrows (B) as well as sense of rotation of the worm (C).
