Description

The invention relates to general engineering, in particular, to devices for acceleration of flywheels.

There are known devices for acceleration of flywheels. A mass containing a flywheel, an engine, a tape transmission and a mechanism for preparing for the next cycle, made in the form of an additional tape transmission. However, these devices are complex, they provide only alternate acceleration of one fly-weight of the other and cannot provide the acceleration process of a flywheel mounted on one shaft with an engine located on another shaft. A disadvantage of the known devices is also the impossibility of using the constant power of the engine at its nominal speed, which is necessary to give the acceleration the desired intensity.

In the proposed device for acceleration of flywheel masses, these disadvantages are eliminated by the fact that the mechanism for preparing for the next cycle is made in the form of a spring motor connected to the accelerated tape cassette and the overrunning clutch installed between this cassette and flywheel, and the belt tape can performed with a variable cross section.

The device contains it flywheel. 1 (or another reduced flywheel mass), the shaft of which is connected to the cassette 2, on which the tape 3 is wound with a metallic or other material, using an overrunning clutch 4. The kaoset 2 is also connected to the moving part of the spring motor 5 ( spiral or any torsion spring). The tape from the cassette 2 goes to the cassette 6, which sits on the shaft of the engine 7. The filling of the cassette 6 is controlled by the limit switch 8.

The device works as follows.

When the engine 7 is turned on on the cassette 6, the diameter of the tape winding is minimal, and the entire tape is on the cartridge 2 in a coil having a maximum diameter. Due to the relatively high gear ratio between

with the coils, the nominal engine speed corresponds to a very small initial angular velocity of the cassette 2, and consequently, associated with it through the included overrunning muff 4 of the flywheel /. Gradually, with a change in the diameter of the coils, the flywheel acquires an increasing speed and reaches its maximum when the coil diameter on the cassette 6 reaches its maximum, and the coil diameter on the cassette reaches 2 minimum values. Spring

feels like The process of acceleration ends with the contact of the coil on the cassette 6 with the limit switch 8, which disconnects the motor 7 from the network.

After that, the overclocked cassettes are quickly stopped by the spring force, the overrunning clutch 4 is disconnected by running out of the flywheel J, and the tape with the spring of the spring 5 is again wound on the cassette 2. After that, the device is ready for subsequent work. The tape can be made both constant and variable thickness, which is necessary to give the acceleration the desired intensity.
