Timing belt making use of the gear and manufacturing method

The present invention relates to a gear and one of the components of the means for forming a power transmission device in a tool, including various machinery for the convenience of conventional industrial and daily life from the prior art, and more particularly The present invention relates to a gear using a timing belt and a manufacturing method thereof, unlike conventional mechanical processing techniques for making a convex-convex protrusion forming a gear in the basic structure of a gear.

As a representative type of conventional gears according to the above technical field, spur gears, bevel gears, helical gears, worm gears, cam gear internal gears and the like are commonly used.

In particular, the present invention, based on the present application filed 10-2011-0098639 filed by the present inventors, the tangible photographs obtained through the experience of experimenting with various embodiments that are considered to be the most desirable to further enhance the completeness as an example and for reference purposes added It is attached for reapplication.

Gears are an important element of the mechanical structure for composing complex power transmission devices such as shifting and rotational direction in a state where gears are normally engaged with each other through two or more combinations. It is known that those manufactured as structures are widely used.

The apparent shape of conventional gears from the prior art may include, for example, circular outer or inner gears having the same radius in any outer diameter with respect to the center of the gear in the case of the most common spur gears. Depending on the application, as well as cam gears such as ellipses and egg shapes, the manufacture of internal gears with teeth formed on the inner side of the gears, rather than the outer diameter of the gears, is not only a very difficult technology, but also eliminates vibration and noise generated during operation. It is a fact that technology is a long-standing wish of the related manufacturing and technology world.

Accordingly, the gist of the invention pursued by the inventor is as follows.

1. In a conventional gear, toothed on the outer circumference and a method of manufacturing the same.

2. In a conventional gear, the tooth is made inside the inner circumference and the manufacturing method thereof.

3. Cam gears of elliptical and various shapes, the making of tooth on the inner circumference and the outer circumference and the manufacturing method thereof.

4. Reduction technology and method for significantly suppressing vibration and noise generated during operation.

5. Only conventional machine tools and tools meet the above-mentioned 1 and 2, 3 and 4 as required by the industrial and machine-building industry, without the need for specific techniques and dedicated machines for the creation and manufacture of gear teeth. In some cases, however, mass production, as well as small quantity batch production, can be easily made at a relatively low cost and widely provided to the related technology through expansion and development of gear manufacturing technology that can respond quickly to demand.

In order to achieve the object according to the above object, the present invention, among the various belts from the prior art, in order to prevent slipping during operation, which is a main feature of the timing belt in particular, the projections formed in the uneven shape on the surface of the belt is a conventional method of use Rather, it is characterized by low-cost implementation and performance similar to those of conventional gears through the reverse idea of application as gears of gears.

More specifically, it is based only on the conventional pulley shape, but fits perfectly to the bottom surface without the projection of the timing belt cut according to the design reflecting the conditions such as the gear ratio and power transmission of the gear to be manufactured. It can respond quickly to small quantity batch production by utilizing structural features that make it easy to manufacture a series of completed gears through relatively simple manufacturing techniques such as fitting to the outer circumference or the inner circumference of the prepared gear body. Of course, there are also advantages.

Gears using various timing belts according to the present invention, and gears of various standards implemented through the manufacturing method thereof, are not only required for conventional gears from the related art but also do not require oiling during operation, which is a unique characteristic of timing belts, There is a characteristic that can realize all the advantages such as driving is very quiet as well as accurate driving control.

In particular, cam gears, such as ellipses and egg shapes, which were difficult to achieve by conventional conventional gear manufacturing techniques, can also be easily and easily manufactured in a gear structure having a series of deformations and unique shapes.

In addition, there is an advantage that the mass production can be implemented as well as small quantities of a variety of relatively inexpensive and easy.

Exemplary diagram through a substantial picture of the embodiment configured.

Hereinafter, the present invention will be briefly described with reference to both the accompanying drawings and reference drawings for the purpose of describing the present invention.

Combination of a conventional timing belt 1 cut into a suitable size and width according to the embodiment and the design specification according to the embodiment and the design standard, fitted to the inner circumferential surface 40 of the inner toothed gear body 4 and fastened. And not only can easily implement the embodiment (1000) of the one complete internal gear through the manufacturing method, but also the timing principle of the timing belt (1) unlike the conventional shape of the prior art on the same principle Through a simple combination and manufacturing method, the timing belt (3) prepared in advance by only the shape deformation that is reversed inside and out through one of the inverse idea is fitted to the outer peripheral surface (30) of the outer gear body (3). Another embodiment 2000 of the completed external gear may also be easily implemented.

As an example according to the supplementary description relating thereto, in the case of the timing belt 2 which merely shows a state in which the timing belts 1 and 2 of substantially the same standard are used in accordance with a normal use method, the projections 100 having irregularities are formed. Is toward the inside and the bottom surface 10 is in the shape of facing out, in the case of the timing belt (2) of the shape of the inverted shape just reversed in and out according to the reverse idea through the present invention, the projections 200 of the irregular shape is out The bottom surface 20 only has a structural difference inwardly facing.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and the accompanying drawings.

1 is a perspective view showing an example of a conventional external gear gear assembled by fitting the timing belt of FIG. 3 to the outer periphery of the gear body of FIG. 4.

As an exemplary embodiment according to an experiment for the completion of the technical gist and a possibility of determining the possibility of the technical gist of FIG. Demonstrating that the embodiment 2000 of the external gear, which is characterized by one completed shape and structure, can be easily implemented through the configuration of fitting and aligning the timing belt 3 which has just turned inside and outside through the idea. FIG. 12 is a diagram illustrating an exemplary embodiment of the embodiment according to a shape before assembling and completing the structure of FIG. 1 or FIG. 9 for supplementary description.

Along with this, the flanged boss 33 is firmly attached to the middle of the gear body 3 having the structure of FIG. 1 and FIG. 12 by bolts so that it can be immediately put into industrial production. Figure 9 for reference with a complete shape is a representative example through a tangible picture of the most preferred embodiment according to FIG.

10 is an exemplary view through a stereoscopic picture of a conventional timing belt pulley, which has been removed from any standard that is an actual component widely used in industrial power transmission devices using timing belts. It is taken as a picture, and if it is described further, the conventional timing belt from the prior art is used to transfer power by engaging and walking to the pulley of such a shape, with the same configuration and structure as the shape of Fig. 1 and 9 for reference It is for comparison necessary to refer to the difference from the gist of the present invention characterized by the manufacturing.

In addition, Figure 11 is an exemplary view through a tangible picture of a conventional timing belt pulley and gear. This reference Figure 11 is an intermediate process that is processed into a gear shape to implement the structure of the reference Figure 10, the timing belt is attached only to prevent the deviated from the driving during the driving, like both ears of rabbit ears are missed Illustrated through the actual picture of the conventional timing belt pulleys and gears not assembled.

FIG. 2 is a perspective view illustrating one conventional timing belt and a perspective view in which the timing belt of FIG. 2 is simply turned upside down. For example, a timing belt of substantially the same size may be used in a typical method of use. In the case of the timing belt (1), which only shows the state as it is, according to the drawings, the convex-convex protrusion 100 faces inward and the bottom surface 10 faces outward. Accordingly, in the case of the timing belt 2 having just turned inside and out, the uneven protrusion 200 faces outward and the bottom surface 20 faces inward.

Illustrated through the actual picture of the embodiment according to the case.

In particular, FIG. 3, which is a perspective view of only the inside and outside of the timing belt 1 of FIG. 2, is a case through the first discovery that led to the induction of motivation and conversion of the most important technical idea in the present invention. In general, since the projection belt-like projections of the timing belt pulley as shown in FIG. 10 are generally engaged, the projections 100 of the timing belt 2 are engaged with each other so as to rotate in a normal manner. If the bottom surface 10 is turned upside down, as in the case of FIG. 3, it is too natural to use it again because it is in fact known by everyone, but the power transmission of the seedlings produced by the present inventors. One day while assembling the device, as usual, it was touched to correct the timing belt (2) that was turned upside down, unlike the usual case as shown in Figure 3 for reference. What if you ever used to take the place of a conventional gear teeth of a shape as is, the protrusion 200? Through this chance, the gist of the present invention, which is caused by the paradoxical change of ideas and motivation, has gradually become a concrete starting point.

Figure 4 is a perspective view through an example of the shape and structure of the gear body processed to the size to cover the timing belt of Figure 3, the boss 33 centered on the hole 35 through which a typical central axis will pass In order to implement the gist of the present invention, a series of conventional gears and belt pulleys or a conventional structure in which a drive shaft of a power transmission device is installed, an external gear body (3) In addition to the outer peripheral portion of the outer gear body outer circumferential surface 30 and based on this, the timing belt (2) just flipped inside and outside according to the reverse idea through the present invention to accurately fit to the gear body outer circumferential surface (30) The timing belt guide 31 for the alignment of the belt and the timing belt 2 due to the sliding phenomenon due to the vibration and the driving force during the operation to prevent the accident It is a simple structure that is processed and manufactured in a basic configuration such as timing belt departure prevention mounds (32).

Referring to FIG. 15 based on an experiment for determining the technical gist of FIG. 4 and determining the possibility, FIG. 15 is an exemplary view through a substantial photograph of an embodiment according to the case of FIG. 4.

Figure 5 is a perspective view through an example of the shape and structure of the gear body processed to fit the timing belt of Figure 2 in accordance with the inner circumference, through a manufacturing process similar to the tips of the basic configuration described as Figure 4 above, the central axis is In order to implement the gist of the present invention, a series of conventional gears and belt pulleys or the like conventional structure in which the drive shaft of the power transmission device is installed through the boss 43 centered on the hole 45 to be penetrated. The timing belt 1 is precisely fitted to the inner circumferential surface 40, which is a position at which a conventional gear is formed, and the alignment of the timing belt 1 is performed based on the internal gear body 4, and according to vibration and driving force during subsequent operation. It is processed and manufactured in the basic configuration such as timing belt release prevention mound 42 for preventing accidents such as timing belt 1 falling out due to the phenomenon of being pushed out. A simple structure.

FIG. 6 is a perspective view showing an example of a conventional inner tooth gear assembled by fitting the timing belt of FIG. 2 to the inner circumference of the gear body of FIG. 5, on the outside of the inner circumferential surface 40 of the inner tooth body 4. Through the configuration to fit and align the timing belt 1 according to the description and tips through the drawings that easily implements the embodiment 1000 of the internal gear structure characterized by another completed shape and structure through the drawings It is explained.

The following are examples of how a series of completed external gears (2000) and internal gears (1000) manufactured according to the gist of the present invention are practically applicable in the field and mechanical configuration in need thereof. It relates to embodiments emphasizing a series of practicality to see if it can.

Figure 7 is a perspective view through an embodiment of a configuration in which another gear is engaged with the outside of the external gear implemented as in the case of FIG. 16 for reference, in the case of FIG. 1 and 9 for reference or FIG. 12 for reference, according to an embodiment 2000 of a series of completed external gears, any of the convex-convex protrusions having the gears formed on the outer circumference thereof may be used. Another external gear 5000 in position relates to operating as a configuration in which the teeth and protrusions are engaged with each other.

The external gear 5000 in FIG. 16 for reference is a pinion according to a conventional embodiment, and is a timing belt pulley made of a metallic material such as duralumin instead of the timing belts 1 and 2 made of a polymer compound. It is empirically explained that it can also be used as external gear.

In addition, FIG. 17 is another typical use example according to FIG. 7, and is an example of an exemplary embodiment of a configuration in which protrusions of a pair of external gears 2000 as shown in FIG. 12 are arbitrarily engaged. As an illustration, the projections 200 having the structure of the cog wheels using the same timing belt 3 can be used as the external gears.

In addition, Figure 18 for reference is another conventional use example according to Figure 7, by engaging the external gear of the shape as shown in Figure 11 for reference to the projection of the outer gear 2000, such as Figure 11 and Figure 12 for reference. As an exemplary view through the actual picture of the configured embodiment, the projection 200 of the external gear of FIG. 1 and the reference FIG. 12 using the timing belt 3 and the reference of FIG. The external gear empirically explained that the external gear may be a pulley for a conventional timing belt made of metal such as duralumin.

8 is a perspective view through an embodiment of a configuration in which another gear is engaged inside the inner tooth gear implemented as in the case of FIG. 6, in an embodiment 1000 of a series of completed inner tooth gears, the gears on the inner circumference thereof; The internal gear 6000, which is a series of planetary gears and pinions, is operated as a configuration in which the teeth and the projections are engaged with each other at an arbitrary position of the irregular projections.

The following relates to a comprehensive supplementary description based on more detailed description of the subject matter through the present invention and the experiences of experiments conducted to increase completeness.

3, if it is difficult to accurately measure the inner circumference and the inner diameter of the timing belt (2) with the protrusions 200 facing outward and the bottom surface 20 facing inward according to FIG. According to the practice and experience, the timing belt (2) is actually inserted and pulled out several times in the middle of biting the material of approximate diameter to the chuck of the lathe, which is a machine tool to be processed first. As a way to determine the exact diameter of the), Figure 15 is an exemplary view through the actual picture of the embodiment according to the case of Figure 4 is the outer peripheral surface of the gear body which is determined to be the most desirable through a number of trial and error like this (30) and the timing belt guide (31) serving as a reference for the alignment so that the timing belt (2) can be fitted in the correct position and The timing belt 2 fitted in this way is processed and processed in the form of a basic configuration such as a timing belt detachment prevention mound 32 for preventing accidents, such as being accidentally slipped out due to a vibration phenomenon and a driving force during a later operation. It is a simple structure manufactured.

Through the same tips as above, 5 is a perspective view through an example of the shape and structure of the gear body processed to fit the timing belt of FIG. 2 to the inner circumference, the inner circumferential surface 40 of the internal gear body 4 and the correct diameter The measuring method of is to be subjected to a number of trial and error as in the case of Fig. 4 and reference 15 above, so that the gear body is determined to be the most desirable to fit the inner peripheral surface 40 and the timing belt (1) to the correct position It is also equipped with a timing belt departure prevention mound (42) to prevent the gear body inner surface and the timing belt guide (4) and the timing belt (1) fitted in this manner from being acted out in advance. The method of implementing a simple structure processed and manufactured into shapes is the same.

In the basic configuration as described above, if omitted from the drawings, but there are additional important technical tips necessary for practical use, although the timing belt is fitted on the outer peripheral surface 30 and the inner peripheral surface 40 of the inner tooth gear body properly fit the actual site Since there is a risk of slipping during the power transmission action in the surface, the external gear body 30 and the internal gear body 40 have small scratches (knurling), which are technical techniques for preventing slip, which are commonly used on the surface of the internal gear surface. In addition, in order to further prevent slippage and detachment of the timing belts 1 and 2, an adhesive may be used on the outer peripheral surface 30 and the inner peripheral surface 40 as well as the bottom surfaces 10 and 20 of the timing belt.

Conventional gears from the related art are mainly made of metal such as steel, so that the heat, vibration and noise caused by friction generated during the action of shifting and power transmission are one of the factors that degrade the product quality beyond the pollution. As a result, technical improvement efforts to reduce this problem are not solved even in today's high technology era.

The gears with the highest noise among these gears are spur gears and bevel gears. To date, spur gears have improved helical gears, and bevel gears have improved spiral bevel gears. Hypoid gears are widely used in the case of favorable axles, but the entropy characteristic of sliding them in the axial direction is the primary disadvantage. In all cases, noise shielding and grease through appropriate storage spaces are appropriate depending on the purpose and role. It is a fact that it operates in lubricating atmosphere such as lubricating oil.

Therefore, the industry is making an effort to reduce noise by changing the material of gear manufacturing to materials such as nylon among engineering plastics, not steel such as steel, but this situation is not made much progress due to its advantages and disadvantages.

Although the original problem of the gears is a realistic problem for the technical developers, the inventors who came up with the technical gist of the present invention were not even interested in solving the problem related to the first, but after the first application (10-2011-0098639) During the course of various empirical embodiments through experiments to further determine technical feasibility and completeness, it was found that in the examples of FIGS. 16, 17 and 18 for reference, very quiet operation was not possible in the past.

In addition, since no lubricant is required, especially compared to the normal use of the timing belt, even in normal high-speed rotations, even though it is not stored in a space for noise shielding and noise shielding, However, it was very fortunate to demonstrate that mechanical noise in ordinary periscopes would not need to be evaluated.

Therefore, even if the inventors did not intend in the first place as described above, the luck found by the inventors may be the case only in case of accidental specific conditions. In the test results through the precision sound wave experiment apparatus according to the material properties conducted by another method to obtain the material, it is observed that the spread of sound waves is blocked due to the difference in natural frequency characteristics of materials, transfer of sound energy between dissimilar materials and difference of beats. Could. That is, in the case of the conventional gears from the prior art, as the gear body as well as the teeth are all made of one material, when the noise is generated by friction and vibration according to the operation, the gear body itself becomes a ringing ring, which causes resonance. As a result, the larger the gear size, the greater the noise.

Thus, in the case of the gear using the timing belt according to the present invention, regardless of the material of the gear body, due to the sound wave transmission and blocking effect of the heterogeneous material configuration using the timing belt as the material of the cogwheel portion The noise reduction effect can be achieved.

Conventional gears, which are conventional gears, must have a boss in the center to be attached to the drive shaft to perform a series of actions. And it will be difficult to understand the specific advantages only by the above description of the structural features, so to explain in more detail the boss 33, which is the main configuration in the middle of the gear body (3, 4) of the outer tooth or internal gear (2000, 1000) 43 are to be drilled in the center of the central shaft hole (35, 45), the drive shaft of the appropriate diameter, such a combination of the boss (33, 34) and the drive shaft may be carried out by the usual bolt, bearing, key, etc. In particular, in the drawings and reference examples according to the present invention has adopted a method of bolting the flange-type boss separately manufactured to the gear body (3, 4), the reason is Since the raw materials for manufacturing the gears of the shapes shown in Figs. 10 and 11 are so expensive, it is possible to solve the problem of excessive waste of materials and costs in order to manufacture a structure in which the boss body and the boss are all formed at the same time as in the conventional gear manufacturing method. It is only because there is an advantage, it is not necessary to follow such an embodiment.

In addition, in the case of mass production of large quantities of small quantities of products, as well as the mobilization of various techniques in the manufacturing method is required. In general, the gear body (3, 4) of course, the full-range bosses (33, 34) were processed using the common material duralumin, but in the case of carrying out in earnest through the invention in the press, casting, molding, injection, laser And a variety of selective flexibility, such as manufacturing in consideration of more various manufacturing techniques such as wire cutting and industry experience and equipped equipment.

The timing belts 1 and 2 described above are only conventional ones that are well known in the related art, but in the case of the conventional timing belts, which can also manufacture gears with small diameters, they are easily purchased on the market as well. Since it does not exist, it is not possible through the conversion of the idea of manufacturing timing belts of various sizes, especially of small diameters, to provide the industry in need thereof in order to realize the object and the spirit of the present invention.

In addition, the timing belt is made of plastic and synthetic rubber as the main material, but in some cases, it is required to be manufactured as a metallic material such as conventional stainless steel, steel, brass, duralumin, etc. Naturally, it was natural that it did not exist in the past, so it is natural to provide a new manufacturing method. The manufacturing method of the above-described metallic materials is prepared in a round shape with appropriate thickness and diameter. This problem is also impossible, as the timing structure of the timing belt can be manufactured in large quantities through another material such as fabrication.

In addition, one of the primary advantages of the timing belt, which is one of the main materials constituting the gist of the present invention, lies in the flexibility of the material. Therefore, the technology and manufacturers, including the technical development and design of the related industry carried out through the present invention by modifying and applying the various gear body (3, 4) manufacturing techniques described above, for example, such as semi-circular, egg-shaped and elliptical And the possibility that the external cam gears can also be manufactured intentionally, and in order to achieve the desired purpose by further utilizing the advantages of the inherent flexibility and various adaptability of the timing belt, which is in fact a feature of the present invention. Will not be.

As described above, a gear using a timing belt and a method of manufacturing the same according to the present invention are designed according to the gist of the present invention, unlike a boss and a cog wheel manufactured at the same time according to a conventional method of manufacturing a gear. It is characterized by the material selection and applicability that various products can be manufactured according to how it is combined with the gear body (3, 4) manufactured separately from the selection and cutting of the timing belt according to the standard. In this case, there is an advantage in the structural ease of manufacturing a gear comparable to the conventional series of gears.

In addition, due to the toughness and flexibility of the original timing belt, it does not need grease and grease even after long-term use, so there is no risk of contamination due to dust and dirt, and noise caused by friction of the teeth during operation. It is possible to manufacture low-cost, high-efficiency gear units that can be exposed to air in the air because there is no need of a lubricating atmosphere for reducing damage and damage, and in particular, simple general-purpose machines and techniques without the need for conventional gear manufacturing machines Any amount of small quantity production through various specifications and designs required by the industrial field can provide a series of finished gears at low cost and quickly through mass production, and thus have various effects and advantages.

Therefore, the present invention through the above description, various substitutions, modifications and changes, as well as further development within the scope of not departing significantly from the spirit of the present invention by those skilled in the art to which the present invention belongs. Since it is possible to easily apply to other similar fields through the above, the above-described embodiments and the accompanying drawings and reference purposes are merely examples in all respects and should not be interpreted limitedly.

The embodiment 2000 and the internal gear 1000 of a series of completed external gears manufactured according to a gear using a timing belt and a method of manufacturing the same according to the present invention are, for example, common automobiles and machine tools. Except for some applications, such as the operation of submerged gears in a lubrication tank, such as a transmission, it can be widely applied to various fields.

Particularly, it does not need lubrication during operation according to the inherent characteristics of the timing belt while acting as a conventional gear in the related art, and it is very quiet operation so as to be unmatched and precise driving control is achieved There is a structural feature that can implement the gist of the present invention to make full use of.

In addition, cam gears such as ellipses and egg shapes, which were very difficult with conventional conventional gear manufacturing techniques, are also machined and manufactured in the shape of the required standard by externally and internally geared bodies 3 and 4, and the timing described in detail above. If the belts (1, 2) are fitted and combined, it is possible to easily manufacture gears of a series of deformations and unique shapes, as well as a small amount of mass production that is relatively inexpensive and easy. It can be implemented at any time.
