BRIEF DESCRIPTION OF THE DRAWINGS The above and other objects,

1 to 5 show a high-pressure pump constituting a reducer using a BLDC (brushless DC motor) motor. The motor shaft 53 has a sine wave ring plate 54 outside the sine wave portion of the sine wave, The souring rings 1 and 2 56 are brought into close contact with the sine wave ring and the souring connecting rods 1 and 2 71 and 72 are connected to the outside of the sine ring and connected to the 9 o'clock input hole 83 of the motion converting cylinder 82, 82) to move left and right;

The left and right movement forces at the 12 o'clock and 6 o'clock output holes 84 and 85 of the motion plate are transmitted to the crush bearings 90 and 91 that are pivotally connected to the 12 o'clock 6 o ' 12, 6 at right angles, 6 o'clock (88, 89) connected to the rotation of the deceleration shaft slows down the speed of action, but the output of the power to achieve a large output force; 6 than in the conventional configuration shown in FIG. 6, it is possible to completely seal one case, because the reduction shaft 93 and the motor shaft 53 are positioned at the center;

This large decelerating force is applied to the central portion of the pump housing 1 which is kept airtight;

The two vanes move 180 degrees from both sides of the upper and lower sides, and the vanes that precede them stop before the vane stops. The vane comes out and discharges the air (or water, oil) Go and stop the jerking action, turn around and push the first vane again;

It is not oval but it can keep the airtightness and it can produce big pressure. The motor also has a large deceleration, it is compact, it has small size and volume, and the price is low.

10 is a folding type tent, which is made of a general resin cloth at the outer side, which is 5 to 10 times larger than that of the inner side, and a long bag is made inward by inserting an expansion lake and another cloth to stitch the bag by sewing. Replaceable;

The inflated lake is inflated to have the same structure as the drawing and then a general tent-like skeleton is formed;

The tent parts are separated from each other, so that they can be easily assembled with buttons or buckles. Air can be separately injected at the time of separation. However, it is difficult to inject air into a general bicycle air injector. So that it will not be a problem unless it is a big wind.

Figure 10 (D) relates to a folding motor boat;

Motor boats can inflict injuries to people in case of a problem. They inject air using multiple rows of expansion lakes, with at least six lines on the upper skeleton, three lines on the lower skeleton, and three lines on the bottom line. It does not require a great deal of effort.

Referring to the detailed operation of FIG.

First, the operation of the motor unit 40 is a direct current non-commutator (BLDC motor) in which the sequential excitation change of the rectifying magnetic poles is performed by the excitation sensor 52, the electromagnetic driving unit, It is an expensive motor that rotates electrons. It is a motor under study by many companies for various advantages such as speed control up to 50,000 RPM at high speed, low noise and rotation without ignition even in gas.

In the present invention, the stator (core) 44 is rolled into a cylindrical shape by winding a silicon steel plate like a spring of a clock, and a stator slot 46 is formed on the side where the rotor 47 is wound,

A slot bolt hole (43) is formed in the slotless surface of the stator core to fix the stator core to the bottom of the motor section (40) surface.

The rotor is arranged such that a flat hexagonal rotating magnetic pole 49 is disposed at an angle of about 30 degrees with respect to the axis inside the upper and lower rotor system board 48 and the interspiel gap 50 is also inclined at an angle of about 30 degrees with a width of 3 mm, Give a closer skew;

The reason why the gap is oblique is that when the rotor of the AC motor is laminated, it smoothly rotates by minimizing the torque ripple in the lamination where the next sections are slightly twisted.

When you rearrange it;

The stator 44 of the motor is wound around the core like a watch winder, and a slot for winding the coil is disposed on the side where the rotor 47 is located. The pole piece of the slot end portion is sharpened and the gap of the pole piece is narrowed, The slot bolt hole 43 is fixed to the lower case 40 of the motor so as to be fixed to the bottom surface of the stator core of the motor;

A motor shaft (53) and a bearing are fitted in the bearing holder (42) at the bottom surface, which is the bottom surface of the center portion of the stator;

Wherein the disk-shaped rotor (47) is press-fitted perpendicularly to the motor shaft to minimize the gap between the rotor and the stator so as to be parallel to the pole piece of the stator, thereby reducing the magnetic resistance.

When you rearrange it;

In a configuration in which many coils are wound around a stator coil to reduce power consumption;

The clockwork type core does not use the core up to the inner side of the cylinder, so the core loss is small. The core height is high, the diameter is large, the thickness is thin, the stimulus is removed from the axis when the weight is the same,

The thickness of the coil is reduced by increasing the height of the core than that of the conventional motor and the electromagnetic drive circuit and the sensor are incorporated in the inner space, thereby making the overall size of the motor small;

And the efficiency is increased by increasing the number of turns of the coil in the slot to reduce the current and also to have a large magnetic force.

The stator coil is wound in more than 2 phases, which can be coiled in one direction and can be easily wound by hand without expensive equipments. The number of parts is low and the cross fire is not generated. This is because the sub-circuit is not a bipolar operation in which a forward current and a reverse current are supplied to the motor coil, but a unipolar current flows in one direction and the switching unit uses one semiconductor switch on one phase.

In other words, you can adjust the speed with a motor that has the advantage of not having low-cost and trouble-free parts.

The rotor is composed of a disk-shaped thin silicon steel plate (or a ferromagnetic plate) and has a hole for perpendicularly inserting a motor shaft that rotates in the center. A flat hexagonal magnetic pole is arranged at an oblique angle. When both the upper and lower rotor-side plates (48) form a wide inter-pole gap, they are not rigid and have a weak magnetic field, and only the rotor side forms a gap with a silicon steel plate of 5 mm or less. So that it became a more solid rotor than the conventional method.

Conventionally, both the upper and lower magnetic poles have a gap of about 10 degrees, but have no effect, so that the magnetic pole 49 has a slope close to about 30 degrees. Respectively.

When you rearrange it;

(49) is equally arranged on the outer side at a position about 30 degrees from the axis between the upper and lower (right and left) side circular disk-shaped rotor-side plates 48 of the disk-shaped rotor, and the lower- Interstitial gap 50 for separating magnetic force is skewed about 30 mm from the axis at intervals of about 3 mm to reduce torque ripple;

The coupling of the rotor can be made thicker on the rotor side of the upper side (sensor side), but the lower side plate is made of steel plate of 0.5 mm or less and both sides of the upper and lower side plate are fitted with non- A DC non-commutator motor, which is a rotor that fixes a rotating magnetic pole and withstands a high speed by inserting a motor shaft (53) at a right angle in the center.

6, the motor shaft 53 and the decelerating shaft 93 are fixed to the center as shown in FIG. 1, A disk 60 is disposed so as to fix the shaft to both sides of the bearing holder 42 and a sinusoidal ring ring 54 is inserted into the right motor shaft of the rotor 47 at right angles to the sine ring 1 2 and the small levers 1 and 2 (71 and 72) connecting the small connecting rods 1 and 2 (57 and 58) to the outside are connected to the 9 o'clock input hole 83 of the motion converting cylinder 82.

The operation of the speed reducer is:

The motion conversion is carried out to move the sine ring 1, 2 (55, 56) and the small lever 70 to the up-and-down movement of the motion converting cylinder 82 to the rotation of the sine wave ring plate 54, The 12 o'clock and 6 o'clock output holes 84 and 85 are also moved so that the 12 o'clock 6 o'clock levers 88 and 89 are inserted into the decelerating shaft 93 The output shaft 93 is rotated by moving the clutch bearings 1, 2 (90, 91).

In other words, the rotation of the motor is detected by the sinusoidal projection from the motor shaft to the rotation of the shaft, the movement of the odd number of sine wave ring plates is 180 degrees from the other position and the small lever is moved to alternately move the crush bearing inserted in the output shaft, It is a principle.

The speed reduction ratio of the decelerating operation is such that the movement of the sine wave ring plate 54 is close to the motor shaft, the length of the small lever is long, the motion conversion input hole is far from the axis, the length of the lever is long at 12:00, It has a large reduction ratio, can be decelerated to thousands of days, is quiet and low cost.

When you rearrange it;

To construct a reducer with a large reduction ratio without noise by using a crutch bearing;

The sine rings 1 and 2 (55 and 56) closely attached to the outer side at 9 o'clock and 3 o'clock by means of an odd number of sine wave ring plates 54 are pressed into the motor shaft 53 at right angles to transmit the rotational force of the motor to the motion converting cylinder 82, The small bars 1 and 2 (81 and 72) are connected to the 9 o'clock input hole 83 of the motion converting cylinder 82 and the 12 o'clock and 6 o'clock output holes 84 and 85 of the moving disk changer 82 12 and 6 o'clock levers 88 and 89 inserted at right angles to the crutch bearings 1 and 2 (90 and 91) which are pivotally connected to the 12 o'clock and 6 o'clock moving bands and fitted to the reduction shaft 93, Noise reduction gear rotates the shaft of the motor to reduce the rotation of the shaft to the crank action of the lever and the crush bearing.

Again;

In a configuration in which many coils are wound around a stator coil to reduce power consumption;

The clockwork type core does not use the core up to the inner side of the cylinder, so the core loss is small. By increasing the height of the core and increasing the diameter of the core,

The height and the diameter of the core are increased to about 1.5 to 3 times as compared with the conventional motor, and the electronic driver circuit and the sensor portion are built in the inside space, thereby making the overall size small and compact;

And the efficiency of the DC rectifier motor can be increased by reducing the current flowing through the coil by a large number of turns so as to have the magnetic force.

2 (A) shows an 8-pole rotating magnetic pole 49 which uses a rotating magnetic pole and a sensor magnetic pole in common for three-phase motor coils of output coils L1, L2 and L3 by a magnetic pole sensor (52-hole sensor) Phase motor coils L1, L2, and L3 by QA, QB, and QC that pass through the logic unit 63 that increases the magnitude of the power of the stator coils L1, L2, and L3 according to the power switching signal to excite the stator coil at the advanced position Phase eight-pole DC non-commutator motor (BLDC) motor that rotates the rotor 47 in response to the pushing and pulling of the rotating magnetic pole 49. In Fig. The gate input signals of QA ~ QC are initialized and stopped to operate late, PSA ~ PSC signals are operating late and stopping a little early. It is an auxiliary circuit to prevent the output switching part from failing due to overcurrent. 63).

The logic circuit detects the rotating magnetic pole 49 and delays the square wave signal generated by the magnetic pole sensors 62 SA1, SB2, and SC3 as an input. The logic circuit combines the signal with the pre-delay signal and combines them to obtain an output.

The synthesized signal of the delay signal and the delayed signal activates QA, QB, and QC, and operates the PSA, PSB, and PSC when both the delay signal and the pre-delay signal are "high voltage". In QA ~ QC, a small amount of current flows, and in PSA ~ PSC, the greatest current flows. Since the power switching elements (PSA ~ C), in which a lot of current flows, , Because it is not easily destroyed because the QA, QB, and QC circuits were operated with the RE stabilization resistor.

When you rearrange it;

In the electronic drive circuit for driving the motor, the power switching part is easily waved with expensive parts. The switching part is turned on slightly faster by QA, QB, and QC with the protection resistors, and is turned off slightly later, DC motorless drive circuit that prevents the motor from being destroyed by lowering the voltage.

(B) is a monostable multivibrator of U1, U2, D1, R1, R2, and C1 that adjusts the speed to obtain a continuous square wave signal. When the VR is rotated rightward, the "H" The current flowing through the motor is increased to adjust the speed of the motor;

The Hall sensors SA1, SB1 and SC1 for detecting the position of the rotating magnetic pole acquire a square wave signal in the "H" state when it is the S pole and a voltage in the "L" state when it is the N pole and sequentially drive the output units QA, QB and QC Rotate the motor.

D5 to D7, which stops the operation of the previous sensor when the following sensor signal goes to "H", may reduce the output current, but may not require the motor when the load is large.

3 (a) is a rotating magnetic pole having four N pole poles, in which excitation current flows in the slots of 1, 4, 7, and 8 out of 12 slots in a single-pole rotor, The slot is a S pole due to the magnetic induction action, and is a table indicating that the rotor moves to the right due to pushing and pulling of the rotor.

At this time, there is no reverse stimulation in which the direction of the arrow to move is wrong, which is a good excitation method.

(B) is the same as above according to the present invention. However, when an eight-pole rotor having an S pole is used as the lower rotating magnetic pole, the efficiency is improved by about 4% It becomes a more preferable motor.

FIG. 4 (a) is a view of a stator made of a rolled core according to the related art, and FIG. 4 (b) is a detailed view for explaining a forming portion of the present invention;

The power of the motor is well formed and the closer the gap between the stator and the rotor is, the larger the rotational force is and the power consumption is reduced.

In general motors, since all the coils are in the inside of the cylindrical core due to the inside feeling, there is a problem that the coil winding is difficult and it is difficult to narrow the gap of the pole pieces in which the magnetic path is formed. However, the coil winding of the present invention can easily wind the coil And the interval of the pole pieces may be narrowed to about 1.5 times of the coil stroke. As a result of experiment, the inventors found that the efficiency of the motor increases slightly when the pole piece is slightly rounded and moves upward as shown in FIG.

The gap between the pole pieces is small and the magnetoresistance is reduced. As a result, the end portion of the pole piece, which is the largest portion of the rotor and magnetic force, is moved upward, and the transmission force of the magnet is increased by the rotor.

As a result of the experiment with the fan of this configuration, it was judged that the temperature increased from 2000 R.P.M to 2080R.P.M, which is about 4%, and the company has been making efforts for raising the efficiency of the motor by 4 ~ 5% for a long time.

If you thicken the entire pole piece, you will have to give it a little round. The bigger the weight is, the bigger the magnetic resistance is because the pole piece end is the largest.

FIG. 5 is a diagram comparing a conventional DC non-commutator motor and a motor of the present invention;

It has been a long time to change to FIG. 1 due to the lack of research in the prior art, which has been described in detail in the above prior art.

FIG. 6 is a schematic view of a conventional speed reducer and a generator section; FIG.

A circular yoke plate for forming a gap between the disc-shaped rotors 51 is formed on both upper and lower sides, but the rotor has a low rigidity and is broken;

In addition, there is a phenomenon in which the motion of the motion converting plate shaft 81 of the decelerating portion and the stiffness of the decelerating shaft 93 are low, causing a large load to be waved.

The rotor stimulation detection sensor unit has been completed in the present invention without the use of a separate stimulus;

The torque ripple at the time of low-speed rotation is so great that the slope of the inter-pole gap between the rotating magnetic poles is increased from 15 degrees to 30 degrees on the motor shaft 53, and the improvement after 7 to 8 years of research has been completed in the present invention .

On the sensor side of the yoke yoke, there is no gap between the poles, and a steel plate with a thickness of about 1 mm is sufficient to stimulate the sensor operation stimulus.

7 is a diagram showing the construction and operation notation of the high-pressure pump of the present invention;

The suction port 2 is arranged on the left side of the right discharge port 3 and is disposed in the middle portion between the input water passage 6 and the output water passage 7.

The vanes 1 and 2 are engaged with the engaging pins 13 on the rotating circular plate 21 which is rotated by a large force of the motor in which the vanes 1 and 9 are rotated by the reduced motor, It can understand the action that air (or water, oil) can keep airtight when it sucks and discharges by rotating it;

(B) is the initial ecological state of Vane 1 (9) and Vane 2 (10).

The upper vane 1 is caught in the fixing hole 18 and the vane 2 rotates. The vane 2 (10) caught in the rotation latching hole 28 moves about 25 degrees and the air in the upper left and lower right Pushing it completely into the upper and lower output channels 7;

The moving magnetic pole N1 of the sheath pin 14 pushed by the pushing magnetic pole N3 is pushed outwardly and pulls the hooking pin 13 of the hooked vane 1 toward the shaft side so that the vane 1 is released from the hook;

(B) to (C) at the moment of discharge, but the inhalation has progressed a lot;

The vane 2 pushes the vane 1 and the moving stimulus N1 of the sheath pin of the vane 1 is pulled by the engaging magnetic pole S4 so that the engaging pin 13 is engaged with the vane rotation engaging hole 28 of the rotating disc 21, The vane 1 is rotated;

The moving pin N1 of the vane 2 that pushes and follows the pressing pin 13 is pushed by the sweeping magnetic pole N2 pushing from above, so that the pin 13 is caught by the vane fixing hole 18 and stops;

In (e), the vane 1 moves to the right, and when the air is sucked in air, the air is moved a little further, and the air is discharged.

When you rearrange it;

Rotates the vanes 1, 2 (9, 10) of the high-pressure pump to the decelerator output shafts 132, 93 that decelerate the rotation of the motor;

In order to rotate the vanes 1 and 2 at the center of the pump, an input water channel 6 is formed inside the outer circular pump housing 1, an output water channel 7 is formed inside thereof, and a connecting water channel is formed in a ring shape from the inside, The pumping chamber wall 26 in which the vane is rotated is disposed at the right and left sides and the vane is caught in the rotation locking hole 28 of the rotary disk 21 which is pressed into the deceleration output shaft 93 The pin 13 is rotated together with the vane and the vane held in the vane fixing hole 18 on the outer side is stopped so that the vane is sucked when the vanes are narrowed and sucked when the vane is widened to perform high pressure pumping Appliances using DC motor speed reducer.

FIG. 8 is similar to the speed reducer of FIG. 1 but has a speed lever 105 on the speed adjusting screw 104 so that a desired speed can be adjusted by turning the screw.

A motor output ring hole 107 is formed in the upper portion of the output ring to press the motor speed regulator 103 having the adjusting screw 104 into the motor shaft 102 of the small motor 101 and press the motor output ring 106 thereon there is;

When the crank moving base 110 is rotated from the motor output ring hole to the 6 o'clock input hole 111 of the motion plate 112 to move the motion plate from side to side;

The 9 o'clock delivery belt 122 is pivotally connected to the 9 o'clock lever 124 in the 9 o'clock output hole 120 of the motion plate;

Connecting the 3 o'clock delivery belt 123 to the 3 o'clock lever 125 to the 3 o'clock output hole 121 of the movement disk;

The end of the 9 o'clock lever 124 is connected to the 9 o'clock B (bearing, 130) fitted to the reduction output shaft 132 at right angles;

When the end of the 3 o'clock lever 125 is perpendicularly connected to the 3 o'clock clutch B (bearing 131) fitted to the reduction output shaft 132,

The deceleration output shaft rotates to the cranking action of the lever and the clutch B to the rotation of the motor;

If the motor rotates at a high speed of several hundreds: 1 and a 1W motor rotates at 50000 R.PM, if the deceleration ratio is 10000: 1, the speed is slower by 5 R.PM, but the force has a deceleration ratio which is 10000 times larger.

When the speed lever 105 is rotated in the clockwise direction, the distance of the motor output ring hole becomes larger at the center of the motor shaft 102, so that the circle drawn by the motor output ring becomes larger and the moving distance of the crank moving base 110 becomes larger, The crank angle of the crank B is increased at 9 o'clock and the crank angle of 3 o'clock is increased, so that the rotation speed of the deceleration output shaft 132 is increased. However, the reduction ratio is decreased and the force is weakened;

When the speed lever 105 is rotated in the counterclockwise direction, the distance from the center of the motor output ring becomes close to the center of the motor shaft 102 to slow the speed. When the output ring is above the motor shaft, It is possible to perform the continuously-variable shifting operation as far as infinite deceleration.

This endless speed reducer has the advantage of having the smallest volume weight and no noise.

Fig. 9A is an operational configuration diagram of a normal speed reducer using two positive clutches and three reverse clutches; Fig.

(B) is a figure that connects only the lever to G1 and G2 in the first and second crush bearings. When G1 is moved to the left and right, the shaft is cranked at the moment of moving to the left and the shaft moves to the left. The axis is moved and is easily moved to the external force.

When G2 is moved, it shifts to the left as well. However, in the direction of clutching, there is no small noise so as not to be compared with the gear type crunch of the bicycle flywheel.

(C), the rotation direction of the shaft is reversely crushed, but the operation is as shown in (B).

(D) has a positive and negative directional axis. If there is no reverse direction and there is no reverse direction. If inverted direction is reversed, it acts as a closure. If G1 and G2 are moved separately, they will clog in the direction of magnetic clutching. The axis does not rotate.

(E) is a sinusoidal curve drawn by the sling 1, 2 (55, 56), and has a constant height difference. The crest of the sinusoidal curve and the height of the crest become the output curve of the motor. The closer the sling interval is, the higher the deceleration becomes. The higher the sine wave frequency, the better the deceleration capability.

(A) comprises:

The sine ring 1, 2 (55, 56) is rotated by the sine wave ring plate 54 to rotate about the motor shaft 53 while moving in a sinusoidal curve; The sole connection rods 1 and 2 55 and 56 and the small rods 1 and 2 57 and 58 are also moved so that the motion conversion cylinder 82 is also moved so that the 12 o'clock output hole and 6 o'clock output holes 84 and 85, (86, 87) move together with the 12 o'clock lever, 6 o'clock lever (88, 89) connected to the crankshaft bearing 1 and 2 perpendicular to the output shaft, The speed at which the shaft 93 rotates continuously is rotated at a slow or large force.

The reverse crutch 1 moves with the crutch bearing 1 due to the action of the counter-movement bar 1 118 and the reverse bar 1;

The reverse clutch 2 moves with the clutch bearing 2 due to the action of the reverse brake 2 (119) and reverse lever 2.

When the speed of the decelerating shaft with the load is high, the reverse-blocking belt 97 further rotates the reverse clutch bearing 98 to be crushed.

In more detail, when the decelerating shaft 3 is rotated forward in the positive crushing operation, the reverse crushing shaft 113 also rotates in the forward direction. At this time, the reverse crushes 1 and 2 are also inserted in the forward direction.

The reverse bearing claw 98 is inserted in the opposite direction. When the deceleration shaft rotates faster when no load is applied, the reverse clutch bearing is crushed. When the reverse clutch shaft 113 rotates to the same position, the deceleration shaft rotates again, Maintain constant speed without rotating faster.

When you rearrange it;

The reverse belt 94 is connected to the outer belt ring of the reverse bearing crutch 98 sandwiched between the belt ring 99 pushed into the reduction shaft 93 and the reverse clutch shaft 64 so that the speed of the reduction shaft 93 is reversed When the speed is higher than the speed of the crutch shaft (64), the reverse bearing cluts the crutch and maintains the constant speed without increasing the speed.

When you rearrange it;

If you insert the crutch bearing in the opposite direction and insert the crutch bearings in the opposite direction, the opposite direction of the shaft will be obtained. In both sides, the length of the lever and the radius of the shaft Reducer using crush bearing with proportional reduction ratio.

The reason why the crush bearing can be used as the decelerator is that the crutch angle does not slip even at 0 degree.
