Abstract

PURPOSE:To maintain a consistently stable exothermic function with a high output, by continuously cooling an electric motor for a rotary element by means of a cooling medium for thereby avoiding the adverse thermal effect of exothermic function. CONSTITUTION:As the electric motor 1a of rotary element 1 has a shield 8 provided via a space 9 along the outer periphery thereof, in conjunction with an introducting tubular member 10 and an exhausting tubular member 11, and thus allows for the continuous ingression of outer cooling air into the space 9 during the operation of electric motor 1a to cool the motor 1a. In consequence, the transmission of heat from a friction heat generator 3 to the electric motor 1a is completely interrupted during the exothermic function of former, whereby protecting the latter from an adverse thermal effect. In particular, as the inner pressure of cylindrical casing 2 is lower than that of space 9 while a reduced-pressure equilibrium state is established inside the cylindrical casing 2, the cooling air flowing into the space 9 through the exhausting tubular member 11 is introduced to deliver into the cylindrical casing through an effective heat exchanging step. The cooling operation is thus carried out with a simple means, and thereby ensuring an improved durability and consistently stable exothermic function.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each figure, 1 is a rotating body disposed in a cylindrical casing 2, which is driven by a tTL motor 1a and a required number of rotating blades 1b. Although the illustration shows a configuration of three rotating bodies 1, any number of rotating bodies 1 may be used as long as it is two or more.

Reference numeral 4.5 denotes a gas inlet port and a gas exhaust port which are in contact with the gas introduction part 6 and the gas outlet part 7 of the cylindrical casing 2, respectively, and either or both of them have a smaller diameter. The passage h'L of the circulating gas is configured to maintain a value smaller than the suction and discharge capacity of each rotating body 1, thereby achieving a constant pressure flat state of desired depressurization or pressurization within the cylindrical casing 2. It is desirable to use this method to improve efficiency. And in the 11th and 4th, the gas 1 inlet 4 and the gas outlet 5 each flow through the valve Ll.

A horizontal ventilation configuration may also be used.

The embodiments shown in FIGS. 1 to 5 and 2 show a structure in which the rotating body 1 is vertically opposed to the cylindrical casing 2, but the embodiment shown in FIG. Installation 1

One end is opened inside the cylindrical casing 2, and the other end is opened inside the cylindrical casing 2.
Reference numeral 12 designates a support plate on which the electric motor 1a can be placed and fixed within the cylindrical casing 2 via the shield 8.

By the way, in the space 81 (9), a white rough fan 13 is disposed on the rotating shaft of the electric motor 1a via an IF connection or a shaft support such as a bearing, as shown by the chain line shown in Figures π1 and 2. It is also possible to cool the inside by strong circulation, and although it is not shown,

! Control the flow of inhaled and expelled gas! r! By rotating the rotating body 1, the inside of the cylindrical casing 2 is depressurized or pressurized, and this state is a desired constant pressure state, and the pressure difference between the inside and outside is maintained in equilibrium.

In this constant pressure equilibrium state, the amount of air injected into the cylindrical casing 2 is 1 in the gap g in the rotation region R of 10 of each rotating body.
The fat produced by this process is subjected to frictional heat generation action in the extra heat generating section 3, and the degree of fear is gradually increased. Then, the gas whose temperature has risen sufficiently is discharged from LI5 at 1:11 in the evening.

・During the operation of the electric motor 1a, the external cold JJ air constantly flows into the space 9 and cold-beats the electric motor 1a, thus causing the friction r throat generating portion 3. 7) It is possible to completely cut off the conduction of 2L of heat at the start of the motor 1a, thereby protecting the motor 1a from heat.

In particular, when the inside of the cylindrical casing 2 is in a reduced pressure state, the pressure inside the cylindrical casing 2 is lower than that inside the space 9, so the discharge 9゛;・Body 11 is 31Q and the space 1 is゛11X
The cooling gas that has flowed into the chamber is sucked into the
It has the advantage that it can be discharged into a cylindrical cushing after a cylinder exchange operation. l Therefore, the cooling effect can be achieved by introducing outside air without taking any special measures.
