FIELD: machine building. ^ SUBSTANCE: device is arranged in a support and is designed to provide a bearing for a unit of a shaft of the beater. The shaft unit consists of a rotating reduction disk, of a rotating shaft whereto there is attached the rotating reduction disk, and of case of bearings wherein the shaft rests on bearings arranged in the case of bearings. The device includes the first wedge-like element sliding along earth surface and the second wedge-like element between the first wedge-like element and the case of bearings of the shaft unit. The second element slides in the direction opposite to first element sliding; the first element, setting off in the direction of its siding, causes set off of the second element in the direction of its sliding. An adjusting device sets the first element off; the case of bearings rests on the bearing device. The bearing device is positioned between the second element and the case of bearings and interacts with a recess in the bearing case complementary relative to the bearing device. The bearing device has convex surface of contact opposite to the recess in the bearing case. Convex surface of contact of the bearing device is set off relative to surface of the complementary recess in the bearings case. There is also disclosed a support for the shaft unit. Also, there is disclosed the beater. ^ EFFECT: reliability of centring. ^ 11 cl, 7 dwg |
