FIELD: mechanics.SUBSTANCE: lower support of an information element of a demonstration plant includes a lower part having the possibility of being fixed on the demonstration plant housing, and upper part installed on the lower part on the bearing, and a conical gear with a shank. Upper part has a flat support part and a cylindrical part, the inner surface of which has the shape of a polyhedron. Cylindrical part is provided from above with a wall with an opening. The shank has an outer surface corresponding to the inner surface of the cylindrical part, has slots and is inserted into the cylindrical part. A hole is made along the shank central axis; slots in the shank reach at least the level of lower section of the hole, and a screw with the diameter that is larger than the hole diameter is screwed into the hole.EFFECT: invention aims at creating a lower support of a demonstration plant that has long service life, and if necessary, can be easily cost-effectively repaired by replacement of individual damaged parts.5 cl, 1 dwg |
