Description

Technical Field

[0001] The present invention relates to a ratchet ring capable of one-way power transmission, and more particularly, to an impact-resistant multi-angle bundled pole backstop ratchet ring that not only simplifies the structure, prevents backlash phenomenon, enables precise operation, but also improves durability to withstand strong impact loads.

Background Art

[0002] Generally, typical devices that transmit only one-way rotation and do not transmit reverse movement include ratchets and cam clutches. In the case of such ratchets or cam clutches, they are applied in various fields such as ratchet wrenches, ratchets for fixing ropes, and inclined conveyors.

[0003] Here, in the case of a ratchet, gears or saw teeth are formed, and it is configured to enable one-way rotation by engaging or disengaging a pole actuated by a spring.

[0004] Also, in the case of a cam clutch, a bearing ball and a reverse rotation prevention cam are formed between the inner ring and the outer ring, enabling one-way rotation. However, during reverse rotation, the cam acts as a wedge to prevent the rotation.

[0005] However, in the case of such a ratchet or cam clutch, during the stop or operation process, a backlash phenomenon occurs where it is pushed backward by a gap during driving. In this case, if a strong impact or overload occurs during the re-operation process, there is a serious problem that the ratchet or cam clutch is damaged and cannot transmit precise rotational power. During long-term use, there are problems with durability, such as the backlash phenomenon becoming severe due to wear of a single pole, bearing ball, or reverse rotation prevention cam.

[0007] The present invention was devised to solve the various problems described above, and aims to provide an impact-resistant multi-angle bundle pole backstop ratchet ring that has structural simplification and precise operation, as well as durability to withstand strong impact loads, by forming an outer ring sawtooth portion on the inner circumferential surface of the outer ring and forming multiple sets of multi-angle bundle poles around the inner ring that engage with the outer ring sawtooth portion.

[0008] Furthermore, the present invention aims to provide an impact-resistant multi-angle bundle pole backstop ratchet ring that minimizes errors by reducing the sawtooth gap and eliminating backlash by configuring the multi-angle bundle poles so that each set of multi-angle bundle poles engages sequentially with the sawtooth of the outer ring at different angles, by subdividing the sawtooth section of the outer ring into a single-pitch interval, thereby reducing the sawtooth gap and eliminating backlash. [Means for solving the problem]

[0009] As a specific means to achieve the above objective, an inner ring mounting hole is provided through the center, and the inner circumferential surface of the inner ring mounting hole is circumferentially The linear section engages during power transmission and the inclined section guides slippage during free rotation.

Or the interference is released, and the outer ring (100) Provides unidirectional rotational force or to allow the inner ring (200) to spin freely. Includes a multi-angle bundle pole unit (300),

[0012] The aforementioned multi-angle bundle pole unit is

[0013] It consists of multiple sets of 1st, 2nd, and 3rd multi-angle bundle poles,

[0014] Each of the first, second, and third multi-angle bundle poles is configured to engage with the outer ring sawtooth portion of the outer ring at sequential positions of different angles.

[0015] The outer ring sawtooth portion of the outer ring is

[0016] It is protruding from the inside , in the axial direction of the outer ring (100) Front and rear stepped sections (130, 130') are formed on the front and rear sides.

[0017] A mounting projection is formed around the rear side of the inner ring, which is attached to the rear stepped portion of the outer ring, and a finishing plate support portion is provided that protrudes from the shaft hole at the front.

[0018] The inner ring is configured such that a finishing plate, which has a through hole formed through the finishing plate support portion, is mounted on the front step portion of the inner ring to restrain the outer ring.

[0019] Here, the first, second and third multi-angle bundle poles are

[0028] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0029] Figure 1 is an exploded perspective view of the impact-resistant multi-angle bundle pole backstop ratchet ring according to the present invention, Figure 2 is a coupled perspective view of the impact-resistant multi-angle bundle pole backstop ratchet ring according to the present invention, Figure 3 is a front cross-sectional view of the impact-resistant multi-angle bundle pole backstop ratchet ring according to the present invention, Figure 4 is a plan cross-sectional view of the impact-resistant multi-angle bundle pole backstop ratchet ring according to the present invention, and Figure 5 is a diagram showing the main part of the multi-angle bundle pole unit of the impact-resistant multi-angle bundle pole backstop ratchet ring according to the present invention.

[0030] As shown in Figures 1 to 5, the impact-resistant multi-angle bundle pole backstop ratchet ring 1 according to the present invention comprises an outer ring 100, an inner ring 200, and a multi-angle bundle pole unit 300.

[0031] First, the outer ring 100 is configured to output power to the outside in the configuration of the impact-resistant multi-angle bundle pole backstop ratchet ring 1 according to the present invention, and is configured to form a circle with an inner ring mounting hole 110 through which the inner ring 200, which will be described later, is mounted.

[0032] In this invention, the outer ring sawtooth portion 120 is formed on the inner circumferential surface of the inner ring mounting hole 110 of the outer ring 100, and the outer ring sawtooth portion 120 is configured to have a continuous straight portion and an inclined portion.

[0033] On the other hand, in the present invention, as described above, the straight portion constituting the outer ring sawtooth portion 120 is configured to engage during power transmission, and the inclined portion is configured to guide sliding during free rotation.

[0034] Furthermore, in the present invention, the outer ring 100 may further include a number of stopping grooves 140 on its outer circumference so as to engage with ordinary stoppers (not shown) at predetermined intervals.

[0035] The inner ring 200 is configured to substantially transmit the main power in the configuration of the impact-resistant multi-angle bundle pole backstop ratchet ring 1 according to the present invention, and is configured to interfere with the outer ring 100 or to release that interference and transmit or release the main power to the outer ring 100.

[0036] For this purpose, in the present invention, the inner ring 200 is configured to have the form of a circular ring with a shaft hole 210 through which a separate rotating shaft (not shown) for transmitting rotational power is connected in the center, and is configured to be inserted into and mounted in the inner ring mounting hole 110 of the outer ring 100.

[0037] Furthermore, the inner ring 200 has numerous bundle pole mounting grooves 220 formed on its outer circumference at predetermined intervals in the circumferential direction so that the first, second, and third multi-angle bundle poles 310, 320, and 330, which will be described later, can be mounted on it.

[0038] Furthermore, in the configuration of the inner ring 200, as in another embodiment, as shown in Figure 6, the inner ring 200 may further include a gear section 250 for transmitting power to the inner ring 200 from the outside, rather than a normal rotating shaft that protrudes outward while covering the rear side of the outer ring 100 and is coupled to the shaft hole 210 of the inner ring 200.

[0039] On the other hand, in the present invention, the outer ring 100 and the inner ring 200 are configured to provide a tight connection and stable sliding operation when joined together.

[0040] To this end, the outer ring sawtooth portion 120 of the outer ring 100 is configured to protrude to a predetermined length into the inner ring mounting hole 110, and front and rear stepped portions 130, 130' are formed on the front and rear of the outer ring sawtooth portion 120.

[0041] The inner ring 200 first has a mounting projection 230 protruding from its rear circumference, which is mounted on the rear stepped portion 130' of the outer ring 100 and slides along it, and a finishing plate support portion 240 is formed at the front, which protrudes from the shaft hole 210.

[0042] The front of the inner ring 200 is finished with a finishing plate 400, and the finishing plate 400 is configured such that its periphery is attached to the front stepped portion 130 of the outer ring 100 and then fastened to the inner ring 200 with bolts to restrain the sawtooth portion 120 of the outer ring, and a through hole 410 is provided in the center through which the finishing plate support portion 240 of the inner ring 200 passes.

[0043] The multi-angle bundle pole unit 300, in the configuration of the impact-resistant multi-angle bundle pole backstop ratchet ring 1 according to the present invention, acts as an intermediary that interacts with the outer ring sawtooth portion 120 of the outer ring 100 to transmit or release power from the inner ring 200 to the outer ring 100. In the present invention, the multi-angle bundle pole unit 300 is configured in multiple sets consisting of first, second, and third multi-angle bundle poles 310, 320, and 330.

[0044] For this purpose, the first, second, and third multi-angle bundle poles 310, 320, and 330 are housed in the bundle pole mounting grooves 220 and are configured to be elastically installed by springs 301 and to extend and retract outwards, and are configured to mesh with the outer ring sawtooth portion 120 of the outer ring 100 to provide rotational force in one direction.

[0045] In this invention, the first, second, and third multi-angle bundle poles 310, 320, and 330 are configured to form sets of three, and each set can consist of four first, second, and third interlocking tools 311, 321, and 331 arranged radially, that is, at 90° intervals.

[0046] In this invention, the first, second, and third meshing tools 311, 321, and 331 corresponding to each set are elastically installed in the bundle pole mounting groove 220 via a spring 301 and configured to have a protruding force, and the tips of each of the first, second, and third meshing tools 311, 321, and 331 are configured with meshing tool sawtooth portions 312, 322, and 332, respectively, consisting of a straight portion and an inclined portion, so as to mesh with the outer ring sawtooth portion 120 of the outer ring 100.

[0047] In particular, in the present invention, when the first, second, and third meshing tools 311, 321, and 331 corresponding to the first, second, and third multi-angle bundle poles 310, 320, and 330 of each set are mounted in the bundle pole mounting groove 220, the first, second, and third meshing tools 311, 321, and 331 are positioned to intersect with each other. That is, the first meshing tool 311 of the first multi-angle bundle pole 310, the second meshing tool 321 of the second multi-angle bundle pole 320, and the third meshing tool 331 of the third multi-angle bundle pole 330 are continuously and repeatedly configured in a rotational direction. Therefore, the sawtooth portions 312, 322, and 332 of the meshing tools mesh with the outer ring sawtooth portion 120 at sequential positions of different angles.

[0048] In other words, in the present invention, one of the first, second, and third meshing tools 311, 321, and 331 of the first, second, and third multi-angle bundle poles 310, 320, and 330, specifically the sawtooth portion 312, 322, and 332 of the meshing tool, engages with the sawtooth portion 120 of the outer ring 100. For example, when the straight portion of the sawtooth portion 312 of the first meshing tool 311 contacts and meshes with the straight portion of the sawtooth portion 120 of the outer ring, the straight portion of the sawtooth portion 322 of the second meshing tool 321 is located at the end of the inclined portion of the sawtooth portion 120 and does not mesh with it, and the straight portion of the sawtooth portion 332 of the third meshing tool 331 is located in the middle of the inclined portion of the sawtooth portion 120. In this way, the meshing sections of the sawtooth portions 312, 322, and 332 of the meshing tool are subdivided within one pitch of the sawtooth portion 120, thus minimizing the sawtooth gap.

[0049] On the other hand, in the embodiments of the present invention, the first, second, and third multi-angle bundle poles 310, 320, and 330, which form multiple sets, were described as a set of three. However, the invention is not limited to this, and the configurations of the first, second, and third multi-angle bundle poles 310, 320, and 330 can be arranged in various ways at equal intervals.

[0050] For example, multiple sets may consist of four multi-angle bundle poles, with each set comprising four engagement tools, or three multi-angle bundle poles, with each set comprising eight engagement tools. Such adjustments in various quantities allow for precise adjustment according to the application in which the impact-resistant multi-angle bundle pole backstop ratchet ring 1 according to the present invention is used.

[0051] The operation of the impact-resistant multi-angle bundle pole backstop ratchet ring according to the present invention, having the configuration described above, will be explained in detail below with reference to the attached drawings.

[0052] Referring to Figures 1 to 5, the impact-resistant multi-angle bundle pole backstop ratchet ring 1 according to the present invention enables unidirectional power transmission, improves durability to withstand strong impact loads through structural simplification, and enables precise drive by subdividing the meshing structure for power transmission to nearly eliminate backlash.

[0053] To this end, first, a separate device (not shown) for outputting separate power is connected to the outer ring 100, and a rotating shaft 10 having a separate power means (not shown) for providing rotational power is connected to the shaft hole 210 of the inner ring 200.

[0054] Next, I will explain its operating mechanism.

[0055] First, we will explain the structure that prevents the inner ring 200 of the impact-resistant multi-angle bundle pole backstop ratchet ring 1 according to the present invention from spinning freely, that is, the structure that prevents the outer ring 100 from rotating in reverse.

[0056] Referring to Figure 7, when no rotational power is supplied to the rotating shaft 10, the inner ring 200 can rotate freely without any power source. In this case, reverse rotation of the outer ring 100 is prevented.

[0057] In other words, when the inner ring 200 rotates to the right, the inclined portions of the first, second, and third meshing tools 311, 321, and 331, which make up the first, second, and third multi-angle bundle poles 310, 320, and 330 respectively, rotate freely as they pass over the inclined portion of the outer ring sawtooth portion 120 of the outer ring 100, thereby preventing the outer ring 100 from rotating in the opposite direction.

[0058] In other words, the meshing tool sawtooth portions 312, 322, and 332 that cross along the outer ring sawtooth portion 120 are the first, second, and third meshing tools 311, 321, and 331, which are elastically mounted on the inner ring 200 via a spring 301. The compressive force of the spring 301 pushes them backward, and the inclined portions of the outer ring sawtooth portion 120 and the meshing tool sawtooth portions 312, 322, and 332 can cross over each other while sliding against one another.

[0059] Conversely, when the inner ring 200 rotates in the opposite direction, i.e., to the left, the meshing tool sawtooth portions 312, 322, 332 formed on any one of the first, second, and third meshing tools 311, 321, 331 of the first, second, and third multi-angle bundle poles 310, 320, 330 engage with the outer ring sawtooth portion 120, thereby preventing forward rotation without supplying power to the rotating shaft 10, and enabling power transmission to the outer ring 100 when a different rotational power is supplied to the rotating shaft 10.

[0060] On the other hand, as described above, when the inner ring 200 is free-spinning or otherwise providing forward rotational power, the present invention can prevent shock during power transmission by reducing the backlash (pushing phenomenon) of the inner ring 200 to near zero.

[0061] This is made possible by a multi-angle bundle pole unit 300 for transmitting the rotational power of the inner ring 200 to the outer ring 100.

[0062] In other words, referring to Figure 8, in the present invention, any one of the first, second, and third meshing tools 311, 321, and 331 of the first, second, and third multi-angle bundle poles 310, 320, and 330 sequentially meshes with the outer ring sawtooth portion 120 of the outer ring 100.

[0063] For example, when the straight portion of the sawtooth portion 312 of the first meshing tool 311 is in contact with the straight portion of the sawtooth portion 120 of the outer ring, the straight portion of the sawtooth portion 322 of the second meshing tool 321 is located at the end of the inclined portion of the sawtooth portion 120 and does not mesh with it, and the straight portion of the sawtooth portion 332 of the third meshing tool 331 is located in the middle of the inclined portion of the sawtooth portion 120. In other words, when the inner ring 200 rotates, the first, second, and third meshing tools 311, 321, and 331 sequentially mesh with the sawtooth portion 120 and provide force, so that the multi-angle bundle pole unit 300 is always in a state of sequentially meshing with the sawtooth portion 120.

[0064] In other words, in this invention, the meshing sections of the meshing tool saw teeth 312, 322, and 332 are subdivided within one pitch of the outer ring saw teeth 120, and as the inner ring 200 rotates freely, the teeth sequentially mesh with each other at sequential positions of different angles to transmit force, thus enabling precise power transmission without backlash during power transmission.

[0065] On the other hand, as shown in Figure 6, the impact-resistant multi-angle bundle pole backstop ratchet ring 1 according to the present invention enables internal and external power transmission, allowing power to be connected internally or externally using a rotating shaft 10 coupled to the axial hole of the inner ring 200.

[0066] This is made possible by a gear section 250 formed around the rear side of the inner ring 200, and a separate power gear 20 meshes with this gear section 250, thereby enabling the transmission of internal and external power and the rotational drive of the inner ring 200.

[0067] As described above, the impact-resistant multi-angle bundle pole backstop ratchet ring according to the present invention maintains a state in which the multi-angle bundle pole unit continuously engages with the sawtooth portion of the outer ring of the outer ring, even when the inner ring is free-spinning. This prevents backlash, thereby improving durability to withstand strong impact loads during operation, and enabling precise operation. [Explanation of symbols]
