TH35548B - Bearing structure for production equipment Kochi type with a turntable - Google Patents

Abstract

DC60 in this invention A bearing structure is provided in the koji forming equipment, which uses a turntable type that can easily and in a short time replace the bearing that supports the turntable, without requiring a lot of work such as disassembly. The ceiling of the kochi making equipment as it was necessary to do before in This turntable type koji maker There will be a turntable (4) rotating around the axis of the disc shaft. Fixed support (3) positioned vertically within the kochi building chamber, fixed side bearing (10) consisting of circularly separated ring segments (11, 12) with the face of the pressure bearing (16a) and the face of the circular bearing (16b) which are sandwiched in a detachable manner. with the shaft that is fixed in place The bearing on the rotating side (30) will consist of separate bearing ring sections. The circular cross-section (31, 32) with the compression bearing face (33a) and the circular bearing face (33b) is sandwiched in a detachable manner to the turntable (4) and the surface of pressure bearing and the surface of the bearing along the circle of the bearing on the fixed side and the surface of The bearing with pressure and the bearing surface along the circle of the bearing on the rotating side are attached to each other and slide between them.

Claims (2)

1. A rotating disc-type koji making machine with discs (4) that can be rotated around a fixed shaft (3) that is vertically positioned inside the koji making chamber (2) is characterized by the fixed shaft (3) including a step (3c) in its axial midpoint which forms the boundary between the large-diameter lower half (3a) and the small-diameter upper half (3b). The fixed bearing section (10) is placed on step (3c) around the small-diameter upper half (3a) and forms two semicircular bearing rings (11, 12) that can be separated in the radial direction and, when connected, form a circular bearing. Each bearing ring (11, 12) has a horizontal T shape in cross-section and includes a thickness, a rectangular sub-base (13) and a tongue (14) protruding towards the sides. Radial bearings are mounted around the outer edge of the intermediate section of the base (13), where the tongue section (14) has an upper face that forms the support (16) which makes up the thrust bearing face (16a), and a vertical face that forms the shoulder which makes up the radial bearing face (16b), where the base (13) has a lower face (13a) resting on the upper face of the step section (3c) of the fixed shaft (3), so that the base (13) of the bearing ring sections (11, 12) are placed on the step section (3a) to create the fixed bearing section (10). The disc (4) is rotatably mounted to the smaller diameter section (3b) of the fixed shaft (3) through a support hole (4a) created at the center of the disc (4), and the rotating bearing (30) is rotatably mounted to the underside of the disc (4) around the support hole (4a). Of the disc (4), the rotating bearing (30) is made of a disc-shaped piece and consists of two semicircular bearing rings (31, 32) that are separable in the radial direction and, when joined, form a circular bearing, in which each bearing ring (31, 32) has a thrust bearing face (33a) on its inferior face and a radial bearing face (33b) on its inner perimeter. The thrust bearing face (16a) and the radial bearing face (16b) of the stationary bearing element (10) are in sliding contact, respectively, with the thrust bearing face (33a) and the radial bearing face (33b) of the rotating bearing element (30). An oil seal (45) is placed on the upper face of the plate (4) around the support hole (4a) for sealing the outer edge of the stationary shaft (3) and the support hole (4a), and a cover (42) is placed on the plate (4) to enclose the stationary bearing element (10) and the rotating bearing element (30) from its outside. The stationary bearing element (10) and the rotating bearing element (30) are self-lubricating bearing elements. The bearing rings (11, 12) that form the stationary bearing element (10) are welded to the bearing ring. The connecting rings (19, 20), aligned with the bearing rings (11, 12) in a tilted phase to create a ring-shaped fixed support element, and the bearing rings (31, 32) that form the rotating bearing element (30) are welded to the connecting rings (36, 37), aligned with the bearing rings (31, 32) in a tilted phase to create a ring-shaped rotating support element. 2. A koji-making machine of the rotating disc type according to Reservation 1, in which the bearing rings (11, 12, 31, 32) and connecting rings (19, 20, 36, 37) are half-rings.
