Abstract

According to the present invention, a driving energy transmission unit using resistance has a resistant axial line to enable a first driven gear and a second driven gear engaged between a driving gear and the ring gear while separated from a predetermined position even if the first driven gear and the second driven gear receives resistance by mutual organic roles of a connector and an elastic member and a third driven gear. Therefore, energy (rotational force) of the driving gear is completely transmitted to the ring gear to rotate a rotational shaft without any loss of the energy.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a driving energy transfer unit,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a drive energy transfer unit using a resistor, and more particularly, to a drive energy transfer unit using a resistor capable of effectively and constantly transferring a predetermined amount of drive energy to a driven shaft without an artificial rotation ratio change.

Generally, in order to transfer the driving energy of the driving source to the slave source, a connection resistance unit that maintains a constant resistance force connecting the driving source and the slave source as shown in the diagram 1 is required. If the resistive force of the connection resistance unit is y, the driving source rotates the slave unit through the resistance of the connection resistance unit.

At this time, the difference in the force between the driving source and the slave source, that is, the driving resistance force of the slave source according to the driving source, occurs.

The correlation between x and y is as follows.

1) If y = 0, the driving force transmitted to the slave station is 0 (idle)

2) If y = x, the circumference of the slave circle is rotated by the circumference of the driving source (when the driving source rotates, the slave is rotated by the circumference of the driving source /

3) If y> x, the number of rotations of the drive source and the slave is the same.

Particularly, in the case of 2) and 3), when the connection resistance unit is constituted and operated, the driving energy (driving force * rotation distance) of the driving source is transmitted around the slave unit through the connection resistance unit, The number of revolutions of the slave is inversely proportional to the difference in force (resistance) between the two. (When the resistance is large, the number of revolutions is small, and when the resistance is low, the number of revolutions is large.) At this time, the rotation ratio of the driving source and the slave source is always in the range of 1: 0 to 1 appear.

Therefore, a connection resistance unit that effectively maintains a constant resistance force is required in order to minimize the energy loss between the driving source and the driven source.

Hitherto, a driving energy transfer unit using resistors of Registered Patent No. 10-1406312 (registered on June 3, 2014) has been proposed by the present applicant. 2, the drive energy transmitting unit using the resistance of this publication includes a drive lever 110, an input shaft 120, a drive gear 200, a first driven gear 210, a first coaxial gear 212 A second driven gear 220, a ring gear 230, a second coaxial gear 222, and an output shaft 240.

The rotational power supplied through the drive lever 110 rotates the input shaft 120 in one direction. A driving gear 200 is formed at an end of the input shaft 120.

A first driven gear 210 and a second driven gear 220 are sequentially engaged with each other in a radial direction from the center of the driving gear 200. A ring gear (230).

That is, when the driving gear 200 rotates in one direction, the first driven gear 210 rotates in the opposite direction, and the second driven gear 220 rotates in the same direction as the driving gear 200 do.

Accordingly, the first driven gear 210 is disposed in parallel with the input shaft 120, and a first coaxial gear 212 disposed coaxially with the first driven gear 210 is provided. Here, a first elastic member 211 interposed between the first driven gear 210 and the first coaxial gear 212 is provided.

The first elastic member 211 has one end portion 211a of the first elastic member formed at one end thereof is inserted into the fixing hole 210a formed at the tooth vertical surface of the first driven gear 210, The other end 211b of the first elastic member 211 formed by cutting the other end of the first elastic member 211 is fitted in a fixing hole (not shown) formed on the tooth vertical surface of the first coaxial gear 212.

That is, the first driven gear 210 and the first coaxial gear 212 rotate in the direction of compressing the first elastic member 211 (the first driven gear and the first coaxial gear rotate in opposite directions The first driven gear 210 and the first coaxial gear 212 rotate together through the symmetrical equilibrium state of the first elastic member 211 by fixing the first elastic member 211 in a state of being rotated do.

Therefore, the rotational power supplied to the input shaft 120 rotates the driving gear 200 and the rotational power of the driving gear 200 is transmitted between the first driven gear 210 and the first coaxial gear 212 Since the first elastic member 211 in the compressed state and the second elastic members 221 in the compressed state between the second driven gear 220 and the second coaxial gear 222 are symmetrically balanced, A unidirectional resistance is generated which is used as a connection resistance.

The output shaft 240 is configured to rotate integrally with the ring gear 230 to receive the final output rotational power of the ring gear 230.

 However, in the driving energy transfer unit using the conventional resistance configured as described above, the first driven gear 210 and the first coaxial gear 212 are connected by the first elastic member 211 to maintain the tension, Since the driven gear 220 and the second coaxial gear 222 are connected to each other by the second elastic member 221 and are maintained in tension independently of each other, The first driven gear 210 and the second driven gear 220 can not sufficiently attenuate the frictional resistance due to the independent tension between the first elastic member 211 and the second elastic member 221, There is a problem that not only the frictional heat is generated severely but also the life of the unit such as failure to deliver the desired drive energy to the ring gear is shortened.

The plurality of third driven gears 30 are rotatably supported at 90 DEG intervals on the edge of the fixed plate 32. An input shaft 14 is provided between the inner diameter of the fixed plate 32 and the outer diameter of the input shaft 14. [ And the bearing is installed so that the fixing plate 32 does not flow.

When the input shaft 14 is rotated in one direction via the driving wheel 12, the driving power transmitting unit using the resistor of the present invention having the above- A plurality of first driven gears 18 meshed with each other at an interval of 90 degrees are rotated in the opposite direction to the outer periphery thereof while the first driven gears 16 rotate. The plurality of second driven gears 20 are rotated in the same direction as the driving gear 16 and the rotational power of the plurality of second driven gears 20 is transmitted to the ring gear 24 meshed with the outer periphery thereof, The output shaft 22 fixed to the outer peripheral surface of the ring gear 24 is rotated in the same direction and at the same time.
