Description

1 / 4 “CONSTRUCTIONAL ARRANGEMENTS IN ROTARY MODULES FOR HYBRID ELECTRO-INERCIAL DIDACTIC MECHANISMS”

[001] This utility model relates to two constructive arrangements in rotating modules to be applied to hybrid electro-inertial mechanisms for didactic, instructional, research and teaching purposes. It has application in the area of ​​motors driven by springs, weights, inertia, together with electricity. The modules are coupled to a speed variator and guards to prevent accidents.

[002] It is known that there are several inventive conceptions of rotational mechanisms driven by gravitational inertia in which weights and counterweights would generate rotational motion capable of contributing to the generation of a useful inertial driving force. Examples of this type are discussed in the following documents: WO03 / 100251 A2, US2008 / 0011552 A1, WO2015 / 040340 A1 and BR102015031774-3. The present utility model is based more specifically on the proposal discussed in document BR202022018086-0 in order to add an improvement to the mechanism, more precisely to the rotating mobile system of weights and loads. The present proposal makes use of a speed variator as described in document BR202023015314-9.

[003] Considering that there are no equivalent proposals in the state of the art and based on the solution available in patent document BR202022018086-0, it was observed that practical use is very restricted because it is a device without a speed variator and, at the same time, has a complex weight and load system construction due to the inclusion of belts and the need for constant displacement of the weights / loads, which ultimately makes assembly and maintenance difficult. Another limitation is the lack of protection for moving parts, a critical factor for accidents even at low speeds. Petition 870250003913, dated 17 / 01 / 2025, page 5 / 15 2 / 4

[004] Based on these limitations and considerations, the present utility model was developed, in two different suggested constructive forms, capable of being coupled to a speed variator, as per BR202023015314-9, and allowing a simplification of the rotary system added to the accident protections.

[005] The utility model can be better understood through the following detailed description, in accordance with the attached figures, where:

[006] FIGURE 1 represents an isometric perspective view of the hybrid electro-inertial mechanism, for didactic purposes, consisting of a radial crankshaft with modules in Model 1;

[007] FIGURE 2 represents a top view of the entire mechanism with modules in Model 1;

[008] FIGURE 3 represents an isometric perspective view of the hybrid electro-inertial mechanism consisting of a radial crankshaft in Model 2;

[009] FIGURE 4 represents a top view of the entire mechanism with modules in Model 2;

[010] FIGURE 5 represents an isometric perspective view of the radial crankshaft mechanism in Model 1 equipped with a safety guard;

[011] FIGURE 6 represents an isometric perspective view of the radial crankshaft mechanism in Model 2 equipped with a safety guard;

[012] FIGURE 7 represents a side view of the mechanism in Model 1 with the safety guard;

[013] FIGURE 8 represents a view of the whole mechanism in Model 1 with the safety guard;

[014] FIGURE 9 represents a side view of the mechanism in Model 2 with the safety guard; Petition 870250003913, dated 17 / 01 / 2025, page 6 / 15 3 / 4

[015] FIGURE 10 represents a top view of the mechanism in Model 2 with the safety guard.

[016] With reference to these figures, one can observe the radial crankshaft with modules in Model 1 (1), the support base (2), the speed variator (3), the drive servo motor (4), the equipment support plate (5), the equipment base (6), the power generator (7), the radial crankshaft with modules in Model 2 (8), the long shaft (9), the shaft coupling (10) and the protection (11), which may vary in its dimensions according to the use of the modules in the Model 1 or 2 configuration.

[017] The aforementioned hybrid electro-inertial mechanism for instructional purposes has a crankshaft containing seven modules with a total mass of 200 kg. These masses or loads are divided and distributed in a kind of radial crankshaft in two models. In Model 1 (1) they are distributed radially on the same axis, while in Model 2 (8), with long axis (9), they are spaced in the same proportion in a longitudinal distribution.

[018] It is suggested that the assembly operate at 296 RPM with a centripetal acceleration of 47 m / s2. In general terms, the mechanism starts its operation with the start provided by the drive servo motor (4). This causes the components of the speed variator (3) to rotate, which distributes its movement simultaneously to the radial crankshaft (1)(8) and to the generator (7). The speed variator (3) amplifies the rotations and the radial crankshaft (1)(8) assists in this process allowing an inertial gain that will be fed into the generator (7).

[019] Considering a drive power (4) for the alternator of 1,000 kVA, a power consumption of 1,413.79 hp is assumed. The power delivered to drive the alternator or generator (7), by the crankshaft (1)(8), would reach approximately 3,448.48 kW. The force required to move the system from static inertia is 198 Nm of torque and, by way of example, a three-phase motor of 30 Petition 870250003913, dated 17 / 01 / 2025, page 7 / 15 4 / 4 hp, with the assistance of the crankshaft (1)(8) would be able to deliver a torque of 712.6 Nm to the generator (7).

[020] Finally, the cabota (1)(8) would be fitted with suitable protection(11) according to the configuration, whether Model 1 (1) or Model 2 (8); differing only in longitudinal dimensions to fit Model 2 (8). Petition 870250003913, dated 17 / 01 / 2025, page 8 / 15
