Method for manufacturing a trackless power transmission wire assembly that can be applied in parallel with tensile and compressive forces

The present invention relates to a method for manufacturing an endless track power transmission wire assembly that can be applied in parallel with the tensile force and the compressive force, the wire assembly according to the present invention, unlike the purpose of use of the conventional wire and the tension force through the tooth blades By applying the compressive force in parallel, there is a characteristic that can be used for three-dimensional power transmission and large capacity power transmission, of course, can also be used for the same purpose as a conventional wire.

Because of its excellent endurance, the wire is mainly used as a means of lifting, dragging and moving heavy objects, or for supporting heavy objects, such as winches, cranes and suspension bridges. On the other hand, when used for the purpose of power transmission, it is limited to a small capacity type, which corresponds to an example used to transfer power by connecting a wire between two axes (drive shaft and driven shaft) whose centers are shifted from each other. This is because the means for connecting the wire to the shaft is unstable as well as the wire is severely twisted during power transmission can not be used for large capacity and has the disadvantage of poor durability. And this is not a wire consisting of a caterpillar, but a simple connection.

Conventional power transmission methods for transmitting power from one place to another are geared, chained, belted, linked, caterpillar, etc. The disadvantages of these methods are that the farther the drive and driven side is, It is difficult to use, the precision is lowered, and the device is very complicated. Moreover, this is especially true when the spatial state between the driving and driven sides is complex and requires a three-dimensional system. However, to date, there is no other means capable of transmitting large power precisely and efficiently under long distance and three-dimensional system conditions. Therefore, the conventional power transmission means having various disadvantages and problems can be used. There is no choice but to be. However, the above-mentioned disadvantages and problems may be easily solved if the conventional wire having excellent characteristics of elasticity and toughness and having a characteristic that can be freely bent in any direction can be used for power transmission. However, chains, belts, etc. can be seamlessly connected at both ends, but there is no way to connect the wires smoothly at both ends. To connect both ends of the wire to each other, use a U-shaped wire buckle and nut to tighten them (I), or loosen both ends of the wire and twist them together one by one. II)

However, there is a problem that wires connected through the conventional method described above cannot be used for power transmission. That is, in the above-mentioned method (I), since the wire buckle is fastened to the portions to which the wires are connected, this is a great obstacle and cannot be used on the wiresave. Since the diameter becomes larger and rugged than the original state, it cannot be used on wiresive too. And both of the above (I) and (II) method has a disadvantage that the connection portion of the wire is weak. On the other hand, even if it is assumed that a method (III) can be obtained in which both ends of the wire can be smoothly connected to each other without using the methods (I) and (II) described above, this can also be used for power transmission. none. The reason is that the friction coefficient acting between the wire and the contact surface of the wire sheave is low, so that the wire produced by the method of the above (III) can be used for power transmission by hanging on the wire sheave as shown in FIG. This is because wiresaves and wires cause severe slippage. More specifically, the wires are not only smooth in appearance, but also infiltrated with oil (lubricating oil) administered during the wire processing, and the wire sheave is processed relatively precisely through machining. If the wiresave is rotated and the wiresave is rotated, the wires may cause severe slipping on the surface of the wiresave. Therefore, even the wire produced by the above-described method (III) cannot be used for power transmission by itself. If the wire sheaves are wired and the wires are rotated after applying excessive tension to the wires, the slip will be slightly reduced, which may not be used for light transmission in a short time, but accuracy cannot be expected. However, even after only a few hours, the wires will eat up the wiresave, as well as the tension of the wires will be lowered, leading to accurate power transmission and causing device breakdown or failure within a short time.

Accordingly, the present invention has been made to provide a power transmission wire assembly having a toothed wing so as to be able to apply a tensile force or a compressive force in parallel with good durability and to transmit power accurately.

In the present invention, when twisting while crossing the six wires with each other, the inclined surface 14 is formed on both sides and the wire fitting groove 13 is formed in the six directions, the connecting jaw 12 is formed on one side and the other side is circular After the groove 15 and the hole 16 are formed, one wire is inserted into the six wire fitting grooves of the wire strain assembly ring 10 in which the cut grooves 17 are formed in two places. The connecting jaw 12 is circular while the seat ring 60 is supplied one by one between the first process and the wire strain assembly ring as the wire strain assembly ring is continuously assembled in one direction. A second step of forcibly inserting into the groove 15, a third step of assembling the wire protection ring 30 one by one on the circumferential surface of each of the wire strain assembly rings to be assembled, and assembling as described above Wire strain Between the lip ring, the inclined surface 24 is formed on both sides and the wire fitting groove 23 is formed in six directions, and the connecting jaw 22 is formed on one side, and the circular groove 25 and the hole 26 are formed on the opposite side. The fourth step of assembling and assembling the toothed blades 20 having a larger diameter than the wire assembly ring as described above at regular intervals after the cutting grooves 27 are formed in two places after being formed, is determined by the fourth step. The fifth step of connecting the wire strain assembly ring and the toothed wing over the entire length of the wire strain, and when the ends of the six wire strands meet each other, the position where each wire strain meets Six wire grippers 40 with protruding jaws 43, 41 and 42 formed on the inner center and both sides, and are composed of a sixth step of gripping six wire strains to be firmly connected at different positions.

EMBODIMENT OF THE INVENTION Hereinafter, the manufacturing method of this invention is demonstrated by attached drawing.

In the present invention made of the sixth step as described above, the wire gripper 40 must stay exactly at the position where the ends of the wire strain meet when the ends of the six strands of wire strain meet at different positions.

Therefore, when the wire assembly ring, the seat ring, the toothed wing, and the wire protection ring come into contact with each other when the wire assembly ring, the seat ring, the toothed wing, and the wire protection ring are close to each other through the above-described method, as shown in FIG. Both ends must be cut precisely so that the ends meet at different positions.

Next, check the point where the ends of the cut wire strain meet and fit the wire gripper described above in place of the wire protection ring.

In this state, the wire assembly ring, the wire protection ring and the toothed blade are fitted through the process as described above to connect the whole in an orbital manner.

Next, check the state where the two ends of the 6-strand wire strain meet and stay inside the six wire grippers, and then use the conventional wire gripper crimping device to reduce the outer diameter as shown in the figure and at the same time to indent the central part. Squeeze.

At this time, the diameter of the wire gripper before being crimped is larger than the diameter of the wire assembly ring, so that the inner diameter of the protruding jaws 41, 42 and 43 of the wire gripper is about 0.5 m / m larger than the outer diameter of the wire assembly ring. Good to do.

When the wire gripper is compressed, the outer diameter of the wire gripper is reduced to be the same as the outer diameter of the wire protection ring, and the protruding jaws 41 and 42 strongly grip and connect both ends of the wire strain.

This state is completed because all 6 wire strains are tightly tightened by the wire gripper, especially 6 wire strains are twisted while crossing each other, and the positions where the ends of the 6 wire strains are connected are different. Even in the case of large tension, the connection of the wire strain can bear the tension without any defect.

Of course, since the tensile force applied to the wire strain will be a force within a range that can be endured by six wire strains, it is safe because the force that exceeds the shear force according to the diameter of the wire strain cannot be applied when the present invention is actually used.

The present invention produced by the above method is completed while connected in an orbital manner as shown in FIG.

At this time, the wire assembly ring and the toothed wing play an important role to improve the durability of the wire strain by providing a place where 6 wire strands can be pinched and pinched, and at the same time, perform a secondary role to receive the tensile force when the wire strain is applied. do.

In addition, the wire protection ring plays an important role to prevent the wire strain inserted in the wire assembly ring and the toothed wire fitting groove of the gears from being in place and to prevent the wire from being damaged from impact or friction from the outside. .

In addition, the present invention plays an important role of improving the durability of the wire strain by preventing the surface of the wire strain from directly contacting the sheave when it is rotated while rubbing through the wire sieve 50 as shown in FIG. 10.

Of course, the wire gripper also performs the basic role of strongly gripping and connecting both ends of the wire strain, and also plays the role of the wire protection ring.

The wire assembly ring and the toothed wing are assembled to each other so that the connecting jaw is formed into each circular groove, but the inner diameter of the circular groove and the hole is slightly larger than the outer diameter of the connecting jaw so that there is a tolerance. The inclined surface is formed, and between each of the seat ring is assembled there is no problem in use because it is naturally rounded when the rotational movement is caught by the wire sieve as shown in FIG.

In addition, since the width of the wire gripper is almost similar to the width when two wire assembly rings are connected, there is no problem in the rounding of the present invention.

Of course, it is natural that the minimum radius that can be rounded, that is, the radius of the wire sheave, will be appropriately determined according to the dimensions of each component of the present invention, so there can be no rounding under unreasonable conditions.

And the outer diameter of the tooth blade does not need to be excessively larger than the outer diameter of the wire assembly ring, it is good to have an outer diameter that can be inserted to the most suitable depth in the tooth blade engaging groove 51 of the wire sheave.

The number of tooth blades described above is determined by design calculations that can transmit power most efficiently depending on the size of the device or the diameter of the wire sheave used.

On the other hand, the material of the wire assembly ring, the toothed wing, and the wire protection ring is good to adopt a metal with high specific gravity and high wear resistance, impact resistance and tensile resistance, as well as the material of the wire gripper.

All parts except wire gripper and wire strain should be heat treated, and surface roughness should be relatively precise.

Of course, the wire gripper itself may be heat treated to some extent, and after finishing the gripping operation, appropriate finishing heat treatment may be applied, but an appropriate method may be adopted depending on the situation.

The number of protruding jaws of the wire gripper (in other words, wire tightening jaws) may be increased and may be concave and convex, such as the teeth of the gear.

Since the wire protection ring overlaps each other on the outer edge of the wire assembly ring, as well as protecting the wire strain as described above, foreign matters and the like do not penetrate.

In the present invention, a method of manufacturing using 6-wire wire strain has been described, but in some cases, 4 or 8 wire or more wire strains may be used, and the manufacturing method is the same even if the number of wire strains is increased or decreased.

At this time, the number of wire fitting grooves of the wire assembly ring and the toothed blade will be adjusted according to the number of wire strains used, and the number of wire grippers will naturally increase or decrease in proportion to the number of wire strains.

Therefore, if the number of wire strain is changed, the shape of the wire assembly ring and the toothed wing will be changed, and the fabrication dimension may be changed.

In addition, the present invention can be applied to industrial devices requiring a tensile force or a compressive force in the pipeline as well as for power transmission due to the structural features as described above.

That is, based on the state of FIG. 10, if the pipeline is installed in the space between the wire sieves and the present invention passes through the pipeline, the present invention, which is moved as the wire sieve rotates, has a tensile force against any material in the pipeline. Or it can act as a compressive force.

In this case, of course, the wire strain can be inserted into the wire fitting groove of the toothed blade and then the remaining space can be filled with another attachment or attachment.

On the other hand, if you present another characteristic part in the present invention manufactured as described above, the connection portion of the wire strain does not cause any problem in the use of the present invention even if the six wire strains are connected to each other.

In other words, the wire strain of the present invention is because the ends of the wire strainer is firmly connected to each other by the above-mentioned eye grippers and the outer diameter of the wire strainer is the same as the outer diameter of the wire strainer. This is because it is in the same state as the outer diameter of the ring and has the same outer shape as that produced through the method of (III) described above.

Therefore, the present invention can be used for accurate power transmission by the gear blades while acting as if the ends of the six wire strains are connected to each other in an infinitely orbital manner.

The present invention, which is completed as described above, can be used very innovatively in numerous power transmission fields and industrial machines as many as possible, and as shown in FIG. 10, the wire sheave 50 made to take the gear blades 20 and If a simple related device is provided, the power transmission system is complicated and three-dimensional, and even if the distance between the driving side and the driven side is far away, it is very economical and has a useful effect of simply transmitting power.

Briefly presenting the field of use or application of the present invention, various power transmission fields (including the three-dimensional method) and the transport and transportation of any object or material, and a device, any object or material requiring an auxiliary power source on one drive line Grinding, cutting, compacting, mixing, scraping, or conveying areas such as solids or liquids, relatively high viscosity fluids, sludge, compost, and manure, and descalers, scrap conveyors, conveyors, etc. It is worth noting that there is no field where it is not applied.
