Description

Technical Field

[0001] This invention relates to a variable speed power transmission clutch system with a multi-output structure, and more specifically to a variable speed power transmission clutch system with a multi-output structure that can transmit power in a non-contact state using a structure of a magnet and a magnetic reinforcement plate. Background Technology

[0002] The content described in this section is merely to provide background information for one embodiment of the present invention and does not constitute prior art.

[0003] Power transmission devices typically come in various forms. The most representative type is the device that transmits physical force through mechanical contact, including power transmission using gears, pulleys, and belts. As mentioned above, paired power transmission devices are called couplers or couplings.

[0004] This type of coupling is used to transmit driving force and connects two different shafts, such as a power shaft that transmits driving force by connecting to a motor or engine, and a load shaft or driven shaft that is connected to the side of a rotating object, such as a pump, so that the two shafts can rotate simultaneously.

[0005] This type of coupling rotates through mechanical connection, which may generate noise, dust, vibration, reduced energy efficiency, low durability, and mechanical wear due to friction.

[0006] In addition, when a high-load rotating object is located on the load shaft or driven shaft during initial operation, the high load is also applied to the drive shaft, which can shorten the life of the motor or engine. Or, when performing emergency stops or emergency rotation direction changes in response to abnormal conditions, frequent mechanical shocks can be transmitted to the drive shaft without any buffering, causing damage.

[0007] Therefore, in order to prevent noise and vibration from mechanically connected couplings, or for example, to prevent the load shaft or driven shaft from stopping rotating due to foreign objects getting stuck in the pump, and to prevent the electric motor of the power shaft from being overloaded, magnetic couplings utilizing the magnetic force of magnets are being used.

[0008] Therefore, various types of couplings have been proposed, the most representative of which is Korean Patent Publication No. 10-2005-0017885 (Non-contact power transmission structure using magnetic force, hereinafter referred to as "prior technology", published on February 23, 2015). It relates to a structure that connects a separate driving shaft and a driven shaft and transmits power simultaneously. Specifically, it provides a non-contact power transmission structure using magnetic force, which can transmit power from the driving shaft to the driven shaft in a non-contact state using magnetic force. It consists of a pair of magnetic bodies, including a first magnet and a second magnet. The first magnet is formed in the center and is composed of either an N pole or a S pole. The second magnet is formed on the periphery of the first magnet and is composed of multiple N poles and S poles.

[0009] However, the disadvantage of the prior art as described above is that the structure that utilizes the attraction and repulsion of the magnets arranged on the power shaft disk and the magnets arranged on the load shaft disk experiences periodic slippage, making it difficult to transmit a certain amount of power, and in order to overcome the periodic slippage, it has an integral structure.

[0010] Furthermore, conventional magnetic couplings, when generating attractive and repulsive forces, produce magnetothermal and resistive heat due to eddy currents. This high heat is a major cause of reduced magnetic force and leads to low energy efficiency. Existing conventional couplings address these issues by installing and operating valves to regulate flow; however, this process is a major cause of overload and introduces mechanical losses and reduced energy efficiency. In other words, the problem is that conventional magnetic couplings cannot effectively transmit power from the motor side to the driven shaft, resulting in low power transmission efficiency. Furthermore, the low power transmission efficiency of the motor makes it difficult to precisely control the rotation of the driven shaft. Summary of the Invention

[0011] The present invention is proposed to solve the aforementioned problems. According to one embodiment of the present invention, the object is to provide a variable speed power transmission clutch system with a multi-output structure, which can transmit power by using magnetic force formed between a rotating unit including a magnetic component and a rotating unit with a magnetic component disposed therebetween a corresponding load shaft or power shaft, thereby minimizing heat generation caused by slippage or eddy current, so as to be able to connect to and operate on one side of the power shaft or load shaft.

[0012] Another objective of the present invention is to provide a variable speed power transmission clutch system with a multi-output structure, which can control the load on the load shaft connected to the rotating object to prevent damage to the power source such as the motor or engine of the power shaft.

[0013] However, the technical challenges that this embodiment aims to address are not limited to those described above, and other technical challenges may also exist.

[0014] To achieve the above objectives, according to one aspect of the present invention, a variable speed power transmission clutch system with a multiple output structure is provided. This system, characterized by driving multiple load shafts corresponding to a single power shaft via eddy currents generated by a magnetic force and a rotor system, comprises: multiple load shafts B arranged concentrically; multiple second rotating units 20, each having a cylinder-shaped main body 21a formed at the end of each load shaft B, and magnets 22 formed around the outer diameter of the cylinder-shaped main body 21a; a first rotating unit 10 arranged facing the outer diameter surfaces of the multiple second rotating units 20, and having a magnetic reinforcement plate 12 formed on the surface opposite to the second rotating units 20, which magnetically reacts with the magnets 22; and a power shaft A coupled to the rotation center of the first rotating unit 10 to provide rotational force.

[0015] The characteristic feature is that the axial configuration of the power shaft A is such that it is parallel to the axial configuration of the load shaft B.

[0016] The feature is that the shaft center of the power shaft A is configured as the inner center of a concentric circle that passes through multiple load shafts B, and the first rotating unit 10 provided at the end of the power shaft A forms a cylindrical main body 11a, which is located at the center of a concentric circle of multiple second rotating units 20. A magnetic reinforcement plate 12 is formed on the outer diameter surface of the cylindrical main body 11a, which is formed to face the magnet 22 formed on the outer diameter surface of the second rotating unit 20.

[0017] The feature is that the center of the power shaft A is configured to pass through the inner center of a concentric circle of multiple load shafts B, and the first rotating unit 10 provided at the end of the power shaft A has a roller-shaped main body 11b, which is arranged to surround the outer concentric circle of multiple second rotating units 20, and a magnetic reinforcement plate 12 is formed on the inner surface of the roller-shaped main body 11b, which is formed to face the magnet 22 formed on the outer diameter surface of the second rotating unit 20.

[0018] The feature is that the axial configuration of the power shaft A is perpendicular to the axial configuration of the load shaft B.

[0019] The feature is that a plurality of load shafts B are arranged radially relative to the axis center of the power shaft A, and a first rotating unit 10 provided at the end of the power shaft A has a disc-shaped main body 11c, and a magnetic reinforcement plate 12 is formed in the disc-shaped main body 11c, which is formed to face the magnet 22 formed on the outer diameter surface of the second rotating unit 20.

[0020] The characteristic feature is that the load applied to the coupling can be controlled by separating or bringing the positions of the first rotating unit 10 and the second rotating unit 20 together.

[0021] The second rotating unit 20 is characterized by comprising: a second main body portion 21; a magnet 22 disposed around the surfaces of the second main body portion 21 and the first rotating unit 10 facing each other; a magnetic force forming plate 23 that contacts one side of the magnet 22 and causes the magnetic force generated from the magnet 22 to be discharged to the outside; and a magnetic force forming fastening connection member 24 that fastens the magnet 22 to the second main body portion 21 and discharges the magnetic force to the outside.

[0022] Its characteristic feature is that the N poles and S poles of the plurality of magnets 22 are arranged alternately.

[0023] The first rotating unit 10 is characterized in that it includes: a first main body 11; and a magnetic reinforcement plate 12, which is attached to the outer periphery of the first main body 11.

[0024] The feature is that an anti-corrosion plate 13 is further provided between the first main body 11 and the magnetic reinforcement plate 12 to prevent corrosion of the first main body 11 and the magnetic reinforcement plate 12 due to eddy current.

[0025] The feature is that a motor 30 is connected to the power shaft A to input power, and a pump 40 is connected to the load shaft B to output power.

[0026] Its characteristic is that attraction is generated only between the magnet 22 and the magnetic reinforcement plate 12, so it can be driven regardless of the polarity change. The polarity change according to the rotation of the magnet 22, i.e., eddy current is generated through the rotor system, and the magnetic reinforcement plate 12 is rotated through the rotor system. Thus, no physical impact or mechanical damage can be achieved when there is an emergency stop during operation or when reversing during forward rotation. Furthermore, due to the buffering phenomenon caused by the space between the two rotating units in a non-contact manner, it can rotate gently in reverse during operation without physical impact or mechanical damage to the power shaft and load shaft.

[0027] The feature is that, in addition to the magnets 22 disposed around the outer periphery of the second main body 21 of the second rotating unit 20, deep magnets 25 are additionally arranged radially around the rotation axis (load axis).

[0028] The feature is that a heating fan 26, which is formed through the axis, is radially added around the rotation axis (load axis) at the center of the second main body 21 of the second rotating unit 20.

[0029] The feature is that, in addition to the magnetic reinforcement plate 12 disposed around the outside of the first main body 11 of the first rotating unit 10, copper plate pores 15 are radially added around the rotating shaft (power shaft).

[0030] The feature is that a heating fan 16, which is formed through the axis, is radially added around the rotation axis (power shaft) at the center of the first main body 11 of the first rotating unit 10.

[0031] As described above, the advantages of the present invention are that it enables non-contact, unloaded power transmission via magnetic force between a rotating unit comprising a magnet disposed on a load shaft and a rotating unit comprising a magnetic force reinforcing plate disposed on a power shaft, thereby being unaffected by mechanical losses, noise, vibration, and dust, and providing stable output without periodic slippage compared to existing magnetic couplings.

[0032] Furthermore, the present invention can rotate in both the forward and reverse directions due to the magnetic coupling of the magnetic force enhancement plate structure, and the rotation speed and output can be controlled by freely adjusting the interval, thereby maximizing energy efficiency.

[0033] In addition, the present invention provides a variable speed power transmission clutch system that allows multiple load shafts to be driven by a single power shaft, thereby providing convenience in use and expanding the scope of application. Attached Figure Description

Figure 4 This is a conceptual diagram illustrating a variable speed power transmission clutch system with a multi-output structure according to a fourth embodiment of the present invention.

[0048] Reference Figures 1 to 5 A variable speed power transmission clutch system is disclosed, which drives multiple load shafts to correspond to a power shaft based on eddy currents generated by magnetic force and rotor system.

[0049] As shown in the figure, the present invention is mainly composed of a load shaft B, a second rotating unit 20, a first rotating unit 10 and a power shaft A.

[0050] More specifically, it includes: a plurality of load shafts B arranged in concentric circles; a plurality of second rotating units 20, each having a cylinder-type main body 21a formed at the end of the load shaft B, and a magnet 22 formed around the outer diameter of the cylinder-type main body 21a; a first rotating unit 10 arranged facing the outer diameter surfaces of the plurality of second rotating units 20, and having a magnetic force reinforcing plate 12 formed on the surface opposite to the second rotating units 20, which reacts magnetically with the magnet 22; and a power shaft A coupled to the rotation center of the first rotating unit 10 to provide rotational force.

[0051] At this point, "magnet 22" means "including electromagnets." "Magnetic reinforcement plate 12" is a general term for substances that have the property of enabling the magnetic force of magnets to function.

[0052] exist Figures 1 to 3 The image shows an example of a configuration in which the axial direction of the power shaft A is parallel to the axial direction of the load shaft B.

[0053] Reference Figure 1 The center of the power shaft A is configured as the inner center of a concentric circle that passes through multiple load shafts B, and the first rotating unit 10 located at the end of the power shaft A forms a cylindrical main body 11a.

[0054] The cylindrical main body 11a is mounted at the center of a concentric circle of a plurality of second rotating units 20. For example, a plurality of second rotating units 20 are arranged in the form of planetary gears around the cylinder of the first rotating unit 10.

[0055] At this time, a magnetic reinforcement plate 12 is formed on the outer diameter surface of the cylindrical main body 11a, so as to face the magnet 22 formed on the outer diameter surface of the second rotating unit 20.

[0056] Figure 6 This is a perspective view showing the second rotating unit having a cylinder-shaped main body according to the present invention.

[0057] Reference Figure 6 The second rotating unit 20 has a second main body 21, namely a cylinder-shaped main body 21a, and a plurality of magnets 22 opposite to the first rotating unit 10 are arranged around the outside of the cylinder-shaped main body 21a.

[0058] At this point, preferably, the N poles and S poles of the plurality of magnets 22 are arranged alternately.

[0059] An insertion groove for mounting a magnet 22 can be formed around the outside of the cylinder-shaped main body 21a. The magnetic force forming plate 23 and the magnetic force forming fastening connection member 24 are inserted and mounted in the insertion groove together with the magnet 22. The magnetic force forming plate 23 contacts one side of the magnet 22 and discharges the magnetic force generated by the magnet 22 to the outside. The magnetic force forming fastening connection member 24 fastens and connects the magnet 22 to the second main body 21 and discharges the magnetic force to the outside.

[0060] At this time, the second main body 21 forms a cylinder-shaped main body 21a.

[0061] The first rotating unit 10 will be described below.

[0062] Figure 7 This is a perspective view showing the first rotating unit having a cylindrical main body according to the present invention.

[0063] Figure 7 This is a perspective view showing a first rotating unit having a cylindrical main body according to the present invention. (Refer to...) Figure 7 The first rotating unit 10 includes: a first main body 11; a magnetic reinforcement plate 12, which is attached to the outer periphery of the first main body 11, but an anti-corrosion plate 13 can also be provided between the first main body 11 and the magnetic reinforcement plate 12 to prevent corrosion of the first main body 11 and the magnetic reinforcement plate 12 due to eddy current.

[0064] Reference Figure 2 The center of the power shaft A is configured to pass through the inner center of a concentric circle of multiple load shafts B, and the first rotating unit 10 located at the end of the power shaft A has a roller-shaped main body 11b, which is arranged to surround the outer concentric circle of multiple second rotating units 20.

[0065] like Figure 8 As shown, a magnetic reinforcement plate 12 is formed on the inner surface of the cylindrical main body 11b, facing the magnet 22 formed on the outer diameter surface of the second rotating unit 20.

[0066] Figure 8 This is a perspective view showing a first rotating unit having a roller-shaped main body according to the present invention. (Refer to...) Figure 8 The first rotating unit 10 has a first main body 11, namely a roller-shaped main body 11b, and a magnetic force reinforcing plate 12, which is opposite to the magnet 22 of the second rotating unit 20, is disposed around the inner surface of the roller-shaped main body 11b.

[0067] At this time, the first main body 11 forms a roller-shaped main body 11b, and an anti-corrosion plate 13 can be provided between the roller-shaped main body 11b and the magnetic reinforcement plate 12 to prevent corrosion of the first main body 11 and the magnetic reinforcement plate 12 due to eddy current.

[0068] Reference Figure 4 A variable speed power transmission clutch system with a multi-output structure can be provided, characterized in that the axial configuration of the power shaft A is perpendicular to the axial configuration of the load shaft B.

[0069] At this time, multiple load shafts B are arranged radially relative to the axis center of the power shaft A. The first rotating unit 10, which is located at the end of the power shaft A, has a disc-shaped main body 11c and a magnetic reinforcement plate 12 is formed in the disc-shaped main body 11c, which faces the magnet 22 formed on the outer diameter surface of the second rotating unit 20.

[0070] The following is for reference Figure 9 The first rotating unit constituting the disk-shaped main body 11c will be described.

[0071] Figure 9 As shown in the perspective view of the first rotating unit having a disc-shaped main body according to the present invention, the first rotating unit 10 has a first main body 11, namely a disc-shaped main body 11c, and a plurality of magnetic force reinforcing plates 12 opposite to the magnet 22 of the second rotating unit 20 are attached around the inner surface of the disc-shaped main body 11c.

[0072] At this time, an insertion slot for mounting the magnetic reinforcement plate 12 can be formed in front of the disc-shaped main body 11c.

[0073] In addition, an anti-corrosion plate 13 can be provided between the disc-shaped main body 11c and the magnetic reinforcement plate 12 to prevent corrosion of the first main body 11 and the magnetic reinforcement plate 12 due to eddy currents.

[0074] The present invention, as described above, is characterized in that the load applied to the coupling is controlled by positioning the first rotating unit 10 and the second rotating unit 20 separately or close to each other.

[0076] Reference Figure 5 The present invention discloses a variable speed power transmission clutch system with a multi-output structure, characterized in that a motor 30 is connected to the power shaft A to input power, and a pump 40 is connected to the load shaft B to output power.

[0077] The variable speed power transmission clutch system with a multi-output structure according to the present invention provides a variable speed power transmission clutch system in which multiple load shafts are driven by a single power shaft, thereby offering the advantages of ease of use and expanded application areas.

[0078] Furthermore, the present invention generates attraction only between the magnet 22 and the magnetic reinforcement plate 12, so it can be driven regardless of the polarity change. The polarity change according to the rotation of the magnet 22 generates eddy currents through the rotor system, and the magnetic reinforcement plate 12 is rotated through the rotor system. This allows for emergency stops or reversals during operation without physical impact or mechanical damage. Moreover, the buffering effect caused by the space between the two rotating units in a non-contact manner allows for gentle reverse rotation during operation without physical impact or mechanical damage to the power shaft and load shaft.

Figure 13 An example is shown in which a heating fan 16 is additionally arranged radially around the rotating shaft (power shaft) and formed through the axis.

The magnetic reinforcement plate 12 formed in the first rotating unit 10 of the present invention may be formed with... Figures 14 to 16 Various heat dissipation patterns 12a are shown in the figure.

[0082] Figure 14 , Figure 16 A heat dissipation pattern 12a with a transverse pattern parallel to the axial direction is shown. Figure 15 An example of a heat dissipation pattern 12a with a longitudinal pattern perpendicular to the axial direction is shown.

[0083] As described above, the present invention enables non-contact, unloaded power transmission via magnetic force between a rotating unit comprising a magnetic reinforcing plate 12 disposed on a load shaft and a rotating unit comprising a magnetic reinforcing plate disposed on a power shaft, thereby being unaffected by mechanical losses, noise, vibration, and dust. Compared with existing magnetic couplings, it can provide stable output without periodic slippage.

[0084] Furthermore, the present invention can rotate in both the forward and reverse directions due to the magnetic coupling with a non-magnetic structure, and the rotation speed and output can be controlled by freely adjusting the interval, thereby maximizing energy efficiency.

[0085] As described above, the motor pump of the present invention can be replaced by a power device such as an engine. Furthermore, the shape and number of the first and second rotating units are not limited, and various modifications are possible.
