[0029] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.
[0030] In the description of the embodiments of the present application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present application, the meaning of "plurality" is at least two, for example, two, three, etc., unless otherwise clearly and specifically defined.
[0031] In this application, unless otherwise specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.
[0032] In this application, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it can mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is "above," "above," or "above" a second feature, it can mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it can mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.
[0033] Motorized rollers are components used in industrial automated conveying systems, providing continuous or intermittent power delivery. Due to their compact structure, easy installation, stable operation, and energy-saving and environmentally friendly features, motorized rollers are widely used in modern logistics, manufacturing, and other fields, such as in roller conveyor lines.
[0034] However, the motorized roller generates noise during operation. For example, conventional installation methods for motorized rollers involve inserting the roller's core shaft into mounting holes in the mounting side panels. This facilitates installation, but gaps exist between the core shaft and the mounting holes in the side panels, preventing the core shaft from being fully secured. During operation, the core shaft can experience radial and axial movement in the mounting holes, colliding with the mounting side panels and generating noise. Furthermore, the vibration of the roller motor can also generate noise during operation.
[0035] In order to solve the above problems, an embodiment of the present application provides a silent electric roller. The solution provided by the embodiment of the present application will be described in detail below in conjunction with the drawings in the specification.
[0036] Figure 1 This is a schematic diagram of the overall structure of a silent electric roller provided in one embodiment of the present application.
[0037] Reference Figure 1 As shown, an embodiment of the present application provides a silent electric roller, comprising a cylinder 100, a roller motor 800, a first shuttle shaft 200, a second shuttle shaft 300, and an elastic member 400. The cylinder 100 can be made of metal and have a central through-hole. The roller motor 800 is disposed within the cylinder 100 and is used to drive the cylinder 100 to rotate. The second shuttle shaft 300 is sleeved on the first shuttle shaft 200. The first and second shuttle shafts 200 and 300 are coaxially arranged and can move along the first shuttle shaft 200. The elastic member 400 is mounted between the first and second shuttle shafts 200 and 300. Under the action of the elastic member 400, the second shuttle shaft 300 tends to move away from the first shuttle shaft 200.
[0038] The first spindle 200 and the second spindle 300 are both disposed within the barrel 100 along the axis of the barrel 100, and are both rotatably connected to the barrel 100. The first spindle 200 and the second spindle 300 are relatively stationary in the circumferential direction. For example, when the first spindle 200 and the second spindle 300 are fixed, the barrel 100 can rotate around the first spindle 200 and the second spindle 300.
[0039] Furthermore, the cross-sectional dimensions of the second spindle 300 gradually decrease as it moves away from the first spindle 200. In other words, one end of the second spindle 300 is tapered. It is understood that after the electric roller is mounted on the mounting side plate, the elastic member 400 causes the second spindle 300 to move along the axis of the drum body 100, away from the first spindle 200. The elastic member 400 constantly exerts an outward force on the second spindle 300 (i.e., away from the first spindle 200), thereby keeping the second spindle 300 pressed against the mounting hole of the roller mounting side plate. This prevents the second spindle 300 from axial movement or radial runout during operation, thereby preventing noise from the electric roller.
[0040] Continue to refer to Figure 1 As shown, the silent electric roller also includes a first bearing 500 and a second bearing 600. Both the first bearing 500 and the second bearing 600 are arranged perpendicular to the axis of the cylinder 100 and fixedly mounted in the cylinder 100. The outer rings of the first bearing 500 and the second bearing 600 are connected to the cylinder 100. The first shuttle shaft 200 is fixedly mounted in the first bearing 500, that is, the outer ring of the first shuttle shaft 200 is fixedly connected to the inner ring of the first bearing 500. The second shuttle shaft 300 is inserted into the second bearing 600, and the end of the second bearing 600 passes through the inner ring of the second bearing 600 and extends outside the cylinder 100. For example, the first bearing 500 and the second bearing 600 can be deep groove ball bearings.
[0041] Figure 2 yes Figure 1 Schematic diagram of the coordination between the first shuttle shaft and the second shuttle shaft in the silent electric roller.
[0042] Reference Figure 2As shown, the first shuttle shaft 200 exemplarily includes a first end 210 and a second end 220. The first end 210 has a circular cross-section, facilitating secure connection with the inner ring of the first bearing 500. The second end 220 has a polygonal cross-section, facilitating secure connection with the mounting side plate. The second shuttle shaft 300 has a cavity 310 at one end, similarly shaped in cross-section. The cross-section of cavity 310 is the same shape as the cross-section of the first end 210 of the first shuttle shaft 200, and the dimensions of the cross-section of cavity 310 are greater than or equal to the dimensions of the cross-section of the first end 210 of the first shuttle shaft 200. The second end 220 of the first shuttle shaft 200 extends into cavity 310, allowing the first shuttle shaft 200 to slide within the cavity 310 of the second shuttle shaft 300. Furthermore, since both have polygonal cross-sections, they can remain relatively stationary in the circumferential direction, preventing relative rotation. The cross-section of the second shuttle shaft 300 at the end away from the cavity 310 is also polygonal, which facilitates its attachment to the mounting side plate and prevents the second shuttle shaft 300 from rotating circumferentially within the mounting side plate. The elastic member 400, which may be a compression spring, is disposed within the cavity 310. One end of the compression spring abuts against the end of the first shuttle shaft 200, and the other end abuts against the second shuttle shaft 300.
[0043] For example, in some examples, the cross section of the first end 210 of the first shuttle shaft 200 is configured as a regular hexagon, and the cross section of the cavity 310 of the second shuttle shaft 300 is configured as a regular hexagon of the same size.
[0044] In some examples, the silent electric roller further includes a bearing seat 700, which is used to secure the first bearing 500 and the second bearing 600. Specifically, the bearing seat 700 includes a first bearing mounting space and a second bearing mounting space. The first bearing mounting space is located at one end of the bearing seat 700, and the second bearing 600 is located at the other end of the bearing seat 700. The bearing seat 700 is fixedly mounted within the cylinder 100 along the axis of the cylinder 100, with the first bearing 500 fixedly mounted in the first bearing mounting space and the second bearing 600 fixedly mounted in the second bearing mounting space. Furthermore, the outer edge of the bearing seat 700 is uniformly distributed with strip-shaped shock-absorbing protrusions, which can absorb some of the vibration between the cylinder 100 and the first and second bearings 500, 600, thereby reducing the noise generated by the vibration. Furthermore, illustratively, to further enhance the vibration-absorbing capability of the bearing seat 700, the bearing seat 700 can be made of plastic.
[0045] Continue to refer to Figure 1As shown, the silent electric roller further includes a roller motor 800, which is fixedly disposed within the drum 100 and is used to provide power for the rotation of the drum 100. Specifically, the housing of the roller motor 800 is directly or indirectly fixedly connected to the drum 100, and the core shaft of the roller motor 800 extends out of the drum 100. Exemplarily, the housing of the roller motor 800 is connected to the drum 100, but the outer diameter of the housing of the roller motor 800 is smaller than the inner diameter of the drum 100 to avoid direct contact between the housing and the drum 100. This prevents vibration generated during the rotation of the roller motor 800 from being directly transmitted from the housing to the drum 100, thereby reducing noise generated during the operation of the electric roller.
[0046] Figure 3 yes Figure 1 A magnified schematic diagram of area A in the middle.
[0047] Reference Figure 1 and Figure 3 As shown, the silent electric roller also includes a shock-absorbing seat 900, which is connected to the roller motor 800 and abuts against the inner surface of the cylinder 100. The diameter of one end of the shock-absorbing seat 900 is equal to the diameter of the shell of the roller motor 800. In the direction away from the roller motor, the diameter of the shock-absorbing seat 900 gradually increases until it abuts against the cylinder 100 (as shown in FIG. Figure 3 In other words, the side surface of the shock absorber 900 partially contacts the inner surface of the cylinder 100, but is partially spaced apart. When the cylinder 100 is subjected to an impact load, the shock absorber 900 effectively absorbs the impact force through its spacing and contraction, preventing the roller motor 800 from experiencing rotational disturbances caused by the impact force and disrupting its dynamic balance.
[0048] In addition, the outer periphery of the shock-absorbing seat 900 is provided with a plurality of shock-absorbing claws 910, which abut against the cylinder 100. For example, the shock-absorbing claws 910 protrude from the shock-absorbing seat 900 and abut against the inner surface of the cylinder 100, thereby effectively absorbing the vibration generated during the rotation of the roller motor 800 and preventing this vibration from being transmitted to the cylinder 100 and generating noise. To ensure the vibration absorption ability of the shock-absorbing seat 900 and the shock-absorbing claws 910, the shock-absorbing seat 900 and the shock-absorbing claws 910 can be configured as plastic.
[0049] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application based on the several embodiments provided in the present application to obtain other embodiments, and these embodiments do not exceed the scope of protection of the present application.
[0050] The above specific implementation methods further explain in detail the purpose, technical solutions and beneficial effects of the embodiments of the present application. It should be understood that the above are only specific implementation methods of the embodiments of the present application and are not intended to limit the scope of protection of the embodiments of the present application.
