Abstract

The present invention is a driven shaft constant speed rotation apparatus capable of freely setting and driving the driven shaft on the load side at any desired speed at any time regardless of the rotation speed of the drive shaft powered by the prime mover.

In ships or large vehicles, two additional engines are operated separately from the main engine to drive the generators, one for generation and one for failure.

The reason is that when the generator is attached to the main engine, it is difficult to obtain a constant frequency because the rotation speed is not constant. In addition, in order to solve this problem, it is possible to configure a device using an electronic component such as a filter list, but in this case, because of the large capacity of the generator, it is because of the very expensive cost.

In this situation, in order to obtain a constant frequency in the generator, two or three engines are required in addition to the main engine, which causes problems such as waste of energy, narrow space, difficulty in handling, and inconvenience due to the efficiency of the internal combustion engine. .

The present invention is attached to the main shaft of the main engine in order to improve this problem, or attached only the hydraulic pump to the main engine and the driven shaft for driving the generator is separated any constant rotation that the generator is always required regardless of the number of revolutions of the main engine It is a device for free setting so that can be done.

Until now, mechanical or hydraulic constant speed rotary devices have been invented, but in the case of mechanical type, the structure is complicated and mechanical friction occurs, which generates heat, making it difficult to operate for a long time with large loss of power, and without adjusting the output. In the case of hydraulic type, the variable flow hydraulic pump is mainly used. Therefore, due to the characteristics of the variable hydraulic pump, the speed and reliability of the rotational speed of the drive are insufficient, the reliability is high, and the free setting of the output is difficult. When the output of the driven shaft is lowered, there is a problem that there is no economic feasibility, such as the loss of power of the drive shaft is very large due to the amount of the driven through the relief valve.

Therefore, to date, it is rarely carried by a large vehicle or a ship.

The present invention uses a hydraulic pump on the driving side and a hydraulic motor on the driven side, the structure is very simple and small in size, free rotation speed setting, quick response to the rotational speed of the drive shaft, loss of power, etc. It was created to be.

By attaching the device, there is no need to carry one additional engine, making the space wider and contributing to the saving of energy.

Technology: Power Train

Conventional technology: There is a mechanical driven shaft constant speed rotating device, but it is hardly used because it is difficult to be composed of general devices such as complex structure, very high friction, high power loss, large size, and unreliable.

Regardless of the rotational speed of the drive shaft, constant speed rotation and free rotational setting of the driven shaft

1) Principle

① Drive the driving hydraulic pump 12 according to the capacity of the generator with the main engine.

② Supply the oil discharged from the pump to the system line.

③ Send the discharged oil to the oil distributor (8).

④ In the oil distributor, the oil is distributed to the low speed hydraulic motor oil inlet 10 and the high speed hydraulic motor oil inlet 11 according to the reciprocation of the rod connected to the slide stand (4).

[The low speed hydraulic motor and the high speed hydraulic motor can be installed separately from the two hydraulic motors. However, the dual hydraulic motor case 17 is constituted by the high speed hydraulic motor shaft 22 inside the low speed hydraulic motor shaft 9. The two hydraulic motors are integrated into one unit by turning and double shaft.]

⑤ The low speed hydraulic motor shaft 9 is connected to the ring gear 5 and the high speed hydraulic motor shaft 22 is connected to the sun gear and drives the driven shaft 20 through the planetary gear center pin 21.

⑥ If the rotation speed of the main engine increases, the oil discharge amount from the hydraulic pump 12 increases, so that the low speed hydraulic motor and the high speed hydraulic motor speed up at the same time.

When the rotational speed of the driven shaft 20 is increased by the terms ⑦ and ⑥, the centrifugal force of the centrifugal weight 2 increases, pushing the speed regulating spring 6 through the slide plate 3 and the slide table 4 and the oil distributor 8 The inside of the oil inlet on the high speed hydraulic motor is opened and the oil inlet on the low speed hydraulic motor is closed so that the rotation speed of the high speed hydraulic motor is increased.

Therefore, the high speed hydraulic motor speed becomes faster and the low speed hydraulic motor speed becomes slow. Since the high speed hydraulic motor shaft is integrated with the sun gear of the planetary gear device and the low speed hydraulic motor shaft is integrated with the ring gear, when the rotation speed of the high speed hydraulic motor shaft is increased and the rotation speed of the low speed motor shaft is decreased, the high speed hydraulic motor shaft is connected with the planetary gear (19) shaft. The rotation speed of the driven shaft 20 becomes slow. Therefore, the rotation speed is slowed down by the action of the centrifugal weight. The rotation speed is adjusted by using the planetary gear characteristics.]

⑧ If the speed of the main engine is slowed down and the amount of oil discharged from the hydraulic pump 12 decreases, the low speed hydraulic motor and the high speed hydraulic motor are slowed at the same time.

⑨ When the rotation speed of the driven shaft 20 decreases according to ⑧ ⑧, the centrifugal force of the centrifugal weight 2 decreases, and the oil inlet on the high speed hydraulic motor side is closed by the speed adjusting spring 6, and the oil inlet on the low speed hydraulic motor side is closed. It is configured to open so that the rotation speed of the low speed hydraulic motor is increased.

Thus, the high speed hydraulic motor speed becomes slower and the low speed hydraulic motor speed becomes faster. The high speed hydraulic motor shaft is integrated with the sun gear of the planetary gear system, and the low speed hydraulic motor shaft is integrated with the ring gear, so that the rotation speed of the high speed hydraulic motor shaft is slowed down and the rotation speed of the low speed motor shaft is increased, which is connected to the planetary gear (19) shaft. The rotation speed of the driven shaft 20 becomes faster. Therefore, the rotation speed is increased due to the action of the centrifugal weight. Therefore, the rotation speed is constantly and naturally adjusted.

The rotational speed is adjusted so that the rotational speed of the driven shaft becomes the set value in contrast with the centrifugal force by adjusting the tension of the spring. According to the construction principle of the device, the hydraulic pressure is automatically adjusted according to the rotational speed of the main engine to set the output and the rotational speed. In other words, the faster the rotational speed of the high-speed hydraulic motor, the faster the rotational speed of the sun gear, the smaller the torque applied to the hydraulic motor. Therefore, the hydraulic pressure is reduced.]

2) composition

① Connect the hydraulic pump (12) driven from the engine of a ship or a large vehicle and the piping as a hydraulic hose (15) to facilitate the supply and recovery of oil, and if necessary, the fan or heat exchanger to prevent the oil temperature from rising. Attach the cooling device of.

② As a whole, components need hydraulic tank, hydraulic hose, hydraulic pump, generator, two hydraulic motors, oil distributor, planetary gear system, rotation speed control device and relief valve.

③ Two hydraulic motors are required for the principle of the device, but considering the volume and appearance of the device, two hydraulic motors in one case are designed and manufactured so that two axes can be arranged in a straight line as shown in FIG.

④ The spring for adjustment in the device should take the form of moderate strength according to the centrifugal force and avoid deformation due to expansion and contraction.

⑤ The driving hydraulic pump (2) is driven by belt, gear, etc. to the main shaft of a large vehicle or ship, and becomes the driving side. The planetary gear pins of the planetary gear device connected to the high speed hydraulic motor and the low speed hydraulic motor are required. It is used to drive the generator.

⑥ Attach each supporting device, pressure gauge, tachometer, etc. in accordance with the explanation of the principle.

⑦ Squeeze the box into the box so that the devices fit within one standard, and only the gauge, drive shaft, driven shaft, and adjustment handle come out.

⑧ Install hydraulic pump (12) separately according to the configuration of device and drive by main engine and connect with hydraulic motor of main device by hydraulic hose.

Reduction of power loss and space by reducing the number of auxiliary engines that must be constantly rotated in industrial machinery, large vehicles and ships by allowing the driven shaft to generate a certain number of revolutions or output regardless of the rotation of the drive shaft. There are advantages such as utilization.
