Title: Hollow shaft for shaft system of ship driving device
Inventor: PFEIFER PETER
IPC: F16C3/02
Filed: 1997-12-12
Abstract: PROBLEM TO BE SOLVED: To economically assure the maintenance of a safety condition on fire, by protecting and coating a layered body of a shaft tube directly with a heat-resisting material, and attaching a cooler to a shaft system in at least a length range of the shaft tube. SOLUTION: A heat-resisting protective coating is formed on a shaft tube of a plastic shaft, and a cooler is further attached to a shafting area which is to be exposed to danger. The protective coating can be formed with a little additional cost during the manufacturing of the shaft tube, and shields the layered body for bearing load, of the shaft tube to be exposed to danger of burning, to the hole and the action of heat, by a time when the cooler is operated to protect the hollow shaft from the heat and the burning. The protective film is used as an auxiliary means of the cooler for fire protection, so that it is unnecessary to consider the burning resistance for 60 minutes.  Further the cooler will do so long as it gives the necessary burning resistance with the protective coating, even though the reaction time and the operation time of the single cooler is not sufficient, and the desired safety condition can be economically kept with the low cost.
