Title: Fixing structure for rotary mounting table
Inventor: ODA MASAAKI
IPC: F24C7/02
Filed: 1989-05-24
Abstract: PURPOSE:To prevent a flying sputter from being mixed during a welding operation and enable a rotary driving force to be smoothly transmitted by a method wherein an inside part of an opening of a cylinder forming a bearing structure is closed by a projection of a rotary table. CONSTITUTION:A cylinder 5 storing a rotary shaft 4 and a projection 1b is connected by a spot welding to a receptacle pan 1 in such a way as it may be rotated while a strip-like projection 1a of the receptacle pan 1 is being fitted to a groove 4a of a rotary shaft 4. The cylinder 5 may constitute the projection 1b as well as a rotary bearing for the rotary shaft 4. A certain sputter is generated when the cylinder 5 is connected to the receptacle pan 1 by a welding operation. However, an inside part of an opening of the cylinder 5 is closed by the projection 1b. Thus, even if the sputter splashes, the projection 1b of trapezoid may form a side wall for preventing the sputtering, resulting in that the sputter may not be adhered to an inside part of the cylinder 5. With such an arrangement, the sputter in case of welding operation is prevented from entering a fitted plane between the rotary shaft and the receptacle pan and a rotating driving force of a motor may be smoothly transmitted to the receptacle pan.
