Description

Technical Field

[0001] The present invention relates to the technical field of rolling, and more particularly, to a novel tension roll. Background Art

[0002] Tension rolls are commonly used devices in strip production units. In traditional strip production units, the roll body of the tension roll is driven to rotate by a motor through a speed reducer. In addition to the motor, speed reducers, couplings, etc. are also required in the transmission strip production unit. The transmission chain is long and the efficiency is low, which is not conducive to energy conservation and consumption reduction. Summary of the Invention

[0003] The problem to be solved by the present invention is: how to reduce the rotational energy consumption of the tension roll.

[0004] To solve the above problems, the present invention provides a novel tension roll, including a core shaft, a stator, a rotor, a motor housing, and a tension roll body. The tension roll body penetrates along its axial direction. The stator is sleeved on the core shaft. The motor housing is sleeved on the stator and is rotatably connected to the core shaft. The rotor is located between the motor housing and the stator and is connected to the motor housing. The motor housing is placed inside the tension roll body and is connected to the tension roll body. The core shaft is coaxially arranged with the tension roll body, and both ends of the core shaft extend out of the tension roll body and are used for fixedly connecting to the frame.

[0005] Optionally, the novel tension roll further includes a spoke plate. A gap is left between the motor housing and the tension roll body. The spoke plate is detachably connected between the motor housing and the tension roll body.

[0006] Optionally, the spoke plates are arranged at intervals along the circumferential direction of the tension roll body.

[0007] Optionally, the novel tension roll further includes a braking mechanism. The braking mechanism is assembled at the shaft end of the core shaft and is used to brake the motor housing.

[0008] Optionally, the novel tension roll further includes a rubber lining layer. The rubber lining layer is coated on the outer wall of the tension roll body.

[0009] Optionally, the novel tension roll further includes auxiliary tools. The auxiliary tools are used to support the tension roll body from the inside after the motor housing is separated from the tension roll body.

[0010] Optionally, a central hole is preset in the core shaft. The central hole is used to leave a power line so that the stator is energized.

[0011] Optionally, the novel tension roll further includes air-cooling fan blades. The air-cooling fan blades are rotatably connected to the core shaft and are used to cool the tension roll body.

[0012] Optionally, a cooling channel is further provided on the mandrel, and the cooling channel is used to access a cooling liquid for cooling the stator and the rotor.

[0013] Optionally, the motor housing is coated with a nano-ceramic coating.

[0014] Compared with the related art, in the novel tension roller of the present invention, the stator is sleeved on the mandrel, and the mandrel and the stator remain stationary during use. The motor housing is sleeved on the stator and rotatably connected to the mandrel. The rotor is located between the motor housing and the stator and connected to the motor housing. After being powered on, the rotor can drive the motor housing to rotate around the axis of the mandrel. Furthermore, after the motor housing is connected to the tension roller body, the tension roller body can rotate around the axis of the mandrel, so that the motor can be directly integrated into the tension roller body. In this way, the use of transmission structures such as couplings can be omitted to save costs. Moreover, since the use of intermediate transmission structures such as couplings is omitted, the power loss can be significantly reduced, thereby reducing energy consumption.

At the same time, it should be noted that the above-described meanings of the X-axis and the Z-axis are only for facilitating the description of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0022] It should be noted that the terms "first", "second", etc. in the description, claims and above-mentioned drawings of the present invention are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present invention described here can be implemented in an order other than those illustrated or described here.

[0023] Combined with Figure 1 As shown, an embodiment of the present invention provides a novel tension roller, which includes a core shaft 1, a stator 2, a rotor 3, a motor housing 4 and a tension roller body 5. The tension roller body 5 penetrates along its axial direction. The stator 2 is sleeved on the core shaft 1, the motor housing 4 is sleeved on the stator 2 and is rotatably connected to the core shaft 1. The rotor 3 is located between the motor housing 4 and the stator 2 and is connected to the motor housing 4. The motor housing 4 is placed inside the tension roller body 5 and is connected to the tension roller body 5. The core shaft 1 is coaxially arranged with the tension roller body 5, and both ends of the core shaft 1 extend out of the tension roller body 5 and are used for fixedly connecting with the frame.

[0024] Specifically, the core shaft 1 and the tension roller body 5 are coaxial. The tension roller body 5 is provided with a through hole, which penetrates the tension roller body 5 along the axial direction of the tension roller body 5, so that the tension roller body 5 forms a cylindrical structure with both ends penetrating. In this way, it is convenient to install the motor housing 4 into the tension roller body 5, and it is also beneficial to the heat dissipation of structures such as the stator 2, the rotor 3, and the motor housing 4. The stator 2 is fixed in the middle of the core shaft 1. The motor housing 4 is sleeved on the stator 2, and the left and right ends of the motor housing 4 are respectively rotatably connected to the core shaft 1 through bearings. The rotor 3 is located between the motor housing 4 and the stator 2, and the rotor 3 is fixedly connected to the motor housing 4, so that the rotor 3 and the motor housing 4 can rotate synchronously. The motor housing 4 is connected to the inner wall of the tension roller body 5. Both shaft ends of the core shaft 1 extend out of the tension roller body 5 and are fixed on the corresponding frame. When in use, both shaft ends of the core shaft 1 are fixed, the core shaft 1 and the stator 2 are stationary. After the stator 2 is powered on, the rotor 3 rotates around the axis of the core shaft 1 and drives the motor housing 4 to rotate synchronously, and then realizes the rotation of the tension roller body 5 around the axis of the core shaft 1 to realize the rotation of the tension roller body 5.

[0025] Therefore, in this embodiment, the stator 2 is sleeved on the mandrel 1. The mandrel 1 and the stator 2 remain stationary during use. The motor housing 4 is sleeved on the stator 2 and rotatably connected to the mandrel 1. The rotor 3 is located between the motor housing 4 and the stator 2 and is connected to the motor housing 4. After being powered on, the rotor 3 can drive the motor housing 4 to rotate around the axis of the mandrel 1. Then, after the motor housing 4 is connected to the tension roller body 5, the tension roller body 5 can rotate around the axis of the mandrel 1, so that the motor can be directly integrated into the tension roller body 5. In this way, the use of transmission structures such as couplings can be saved to reduce costs. Moreover, since the use of intermediate transmission structures such as couplings is omitted, the power loss can be greatly reduced, thereby reducing energy consumption.

[0026] Optionally, as shown in combination with Figure 1 and Figure 2 the new type of tension roller further includes a web 6. A gap is left between the motor housing 4 and the tension roller body 5. The web 6 is detachably connected between the motor housing 4 and the tension roller body 5.

[0027] Specifically, the outer diameter of the motor housing 4 is smaller than the inner diameter of the tension roller body 5, so that a certain gap is left between the motor housing 4 and the inner wall of the tension roller body 5. A boss extending radially along the inner wall of the tension roller body 5 is provided. The web 6 is detachably connected between the motor housing 4 and the tension roller body 5 by bolts.

[0028] In this way, by leaving a gap between the motor housing 4 and the tension roller body 5, the existence of the gap can delay the heat transfer between the tension roller body 5 and the motor housing 4 to improve the adaptability of the motor housing 4 and the tension roller body 5 in a high-temperature environment. Then, by detachably connecting the web 6 between the motor housing 4 and the tension roller body 5, the tension roller body 5 and the motor housing 4 can be disassembled separately, which is convenient for manufacturing.

[0029] Optionally, as shown in combination with Figure 1 the webs 6 are arranged at intervals along the circumferential direction of the tension roller body 5.

[0030] Specifically, the webs 6 are arranged at intervals along the circumferential direction of the tension roller body 5, which can also be understood as being arranged at intervals around the mandrel 1.

[0031] In this way, by arranging the webs 6 at intervals along the circumferential direction of the tension roller body 5, the area between two adjacent webs 6 can make the tension roller body 5 communicate with the external environment, enabling the motor housing 4, the stator 2, and the rotor 3 to exchange heat with the external air. While improving the cooling effect of the tension roller body 5, it can also cool the motor housing 4, the stator 2, and the rotor 3.

[0032] Optionally, as shown in combination with Figure 1As shown, the new tension roller further includes a braking mechanism 7, which is assembled at the shaft end of the mandrel 1 and is used to brake the motor housing 4.

[0033] Specifically, the braking mechanism 7 can be a band brake, that is, it can be understood as braking by a brake disc. During installation, the brake disc is sleeved on the right end of the mandrel 1 and rotates synchronously with the motor housing 4. When braking is required, the rotation of the brake disc is restricted.

[0034] In this way, the braking mechanism 7 is assembled at the shaft end of the mandrel 1, and the braking of the tension roller body 5 can be achieved through the braking mechanism 7, which is convenient for the use of the tension roller body 5.

[0035] Optionally, the new tension roller further includes a rubber lining layer 8, which is coated on the outer wall of the tension roller body 5.

[0036] Specifically, the rubber lining layer 8 is coated on the outer wall of the tension roller body 5 to increase the roughness of the outer wall of the tension roller body 5.

[0037] In this way, by coating the rubber lining layer 8 on the outer wall of the tension roller body 5, the friction coefficient of the outer ring of the tension roller body 5 can be improved, and the slipping of the tension roller body 5 can be avoided, so as to improve the application effect of the tension roller body 5.

[0038] Optionally, as shown in combination Figure 3 The new tension roller further includes a fixture 9, which is used to support the tension roller body 5 from the inside after the motor housing 4 is separated from the tension roller body 5.

[0039] Specifically, the fixture 9 includes a central shaft and two support plates sleeved on the central shaft. The central shaft passes through the tension roller body 5 along the axis of the tension roller body 5. The two support plates are detachably connected to the inner wall of the tension roller body 5. When the tension roller body 5 is used for a long time and needs to be ground, the web plate 6 is disassembled, the motor housing 4 is separated from the tension roller body 5, and then the fixture 9 is connected to the tension roller body 5. The fixture 9 supports the tension roller body 5, and the tension roller body 5 can be ground under the support of the fixture 9.

[0040] In this way, by supporting the tension roller body 5 with the fixture 9 after the motor housing 4 is separated from the tension roller body 5, it is convenient for grinding the tension roller body 5.

[0041] Optionally, the mandrel 1 is provided with a central hole, which is used to leave a power cord so that the stator 2 can be powered on.

[0042] Specifically, the central hole extends along the axis of the mandrel 1, and the power cord passes through the central hole and is connected to the stator 2, so that after the stator 2 is powered on, it can drive the rotation 3, the motor housing 4 and the tension roller body 5 to rotate.

[0043] In this way, the central hole is preset by the core shaft 1, and the central hole is used to retain the power line so that the stator 2 can be powered, which can facilitate the stator 2 to be powered and reduce the difficulty of the stator 2 to be powered.

[0044] Optionally, the novel tension roller further comprises an air-cooling fan blade, which is rotatably connected to the core shaft 1 and is used to cool the roller body 5 of the tension roller.

[0045] Specifically, the air-cooled fan blade is rotatably sleeved on the core shaft 1 , and can be driven to rotate by a driving structure such as a motor. When in use, the air-cooled fan blade can accelerate the air flow around the tension roller body 5 to cool the tension roller body 5 .

[0046] In this way, the air-cooling fan blade is rotatably connected to the core shaft 1 and is used to cool the tension roller body 5. The rotation of the air-cooling fan blade can be used to cool the tension roller body 5 so that the tension roller body 5 can meet the requirements of use in a high temperature environment.

[0047] Optionally, a cooling channel is also provided on the core shaft 1 , and the cooling channel is used to access cooling liquid for the stator 2 and the rotor 3 .

[0048] Specifically, the cooling channel is arranged on the side wall of the core shaft 1 and extends axially along the core shaft 1. The cooling channel can be connected to the cooling liquid. When in use, the cooling liquid in the cooling channel forms a low-temperature environment for the core shaft 1, and can exchange heat with the stator 2 and the rotor 3 to achieve cooling of the stator 2 and the rotor 3.

[0049] In this way, cooling liquid is connected through the cooling channel to cool the stator 2 and the rotor 3, which can reduce the impact of the high temperature environment on the structure of the stator 2 and the rotor 3, and form a composite cooling structure with the air-cooled fan blades mentioned above to increase the service life of the stator 2 and the rotor 3.

[0050] Optionally, the motor housing 4 is coated with a nano-ceramic coating.

[0051] Specifically, the nano ceramic coating is coated on the outer layer of the motor housing 4 .

[0052] In this way, the nano-ceramic coating can improve the corrosion resistance and wear resistance of the motor housing 4 and adapt to high temperature environments to improve the applicability in harsh working conditions such as metallurgy and chemical industry.

[0053] This embodiment also provides a strip steel production unit, including the above-mentioned new tension roller.

[0054] The strip steel production unit has all the beneficial effects of the new tension roller, which will not be described in detail here.

[0055] Although the present invention is disclosed as above, the scope of protection of the present invention is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will all fall within the scope of protection of the present invention.
