Description

Technical Field

[0001] This utility model belongs to the field of transmission performance testing technology, and in particular relates to a dynamic torque tester for couplings. Background Technology

[0002] Magnetic drive is a transmission method that uses magnetic force to generate rotational force. It generates torque at the input end of the transmission device through the action of magnetic force, thereby transmitting power. The basic principle of magnetic drive is to use the force of interaction between the magnetic fields generated by induced current to transmit power. When current passes through a conductor, a magnetic field is formed around the conductor. When the magnetic field of the conductor interacts with the magnetic fields of other conductors, a force is generated. This force does not require direct contact; the purpose of transmitting power is achieved through the action of the magnetic fields.

[0003] Traditional transmission structures require a torque meter to measure the torque parameters of the shaft. Existing torque meters are generally suitable for shaft torque measurement. During shaft torque measurement, because the transmission part is a fixed coupling, existing torque meters cannot move dynamically. For transmission shafts of different lengths, the shaft needs to be stopped and the distance adjusted before the measurement can be started. Magnetic transmission couplings are non-contact and the length is dynamically adjustable. Therefore, traditional torque meters are not suitable for magnetic transmission torque measurement.

[0005] To achieve the above objectives, this utility model provides a dynamic torque tester for couplings, comprising a base, a torque detection mechanism, a moving mechanism, a magnetic coupling, and a drive source.

[0007] Optionally, the moving mechanism includes a guide rail, an adjustment component, and a moving seat. The guide rail is disposed on the base, and the moving seat is slidably connected to the guide rail.

The mounting frame is arranged in an L-shape. The horizontal section of the mounting frame is slidably connected between the two sets of guide rails. The housing is disposed on the mounting frame.

[0015] The coupling dynamic torque tester provided in this utility model embodiment has at least one of the following technical effects: the moving mechanism drives the first magnetic ring to move, so that the distance between the first magnetic ring and the second magnetic ring can change along a preset vertical direction.

The following description is based on the accompanying drawings. Figures 1-4 The described embodiments are exemplary and intended to explain embodiments of the present invention, and should not be construed as limiting the present invention.

[0032] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0034] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0035] In one embodiment of this utility model, such as Figures 1-4 As shown, a dynamic torque tester for couplings is provided, including a base 100, a torque detection mechanism 200, a moving mechanism 300, a magnetic coupling 400, and a drive source 500. The torque detection mechanism 200 is disposed on the base 100; the moving mechanism 300 is disposed on the base 100, and the output end of the moving mechanism 300 reciprocates between the torque detection mechanism 200 and the drive source 500; the magnetic coupling 400 includes a first magnetic ring 410 and a second magnetic ring 420, which are respectively disposed on the moving mechanism 300 and the output end of the torque detection mechanism 200; the drive source 500 is disposed on the moving mechanism 300 and is drivenly connected to the first magnetic ring 410.

[0036] In this embodiment, both the first magnetic ring 410 and the second magnetic ring 420 are provided with a plurality of spaced magnetic elements. The magnetic poles of any two adjacent sets of magnetic elements on the same magnetic ring are opposite to each other. When the distance between the first magnetic ring 410 and the second magnetic ring 420 is shortened, the magnetic elements on the magnetic rings realize magnetic transmission by the magnetic field generated according to the corresponding magnetic poles.

[0037] Specifically, the moving mechanism 300 drives the first magnetic ring 410 to move, allowing the distance between the first magnetic ring 410 and the second magnetic ring 420 to change along a preset vertical direction. During the movement, the drive source 500 drives the first magnetic ring 410 to rotate, which in turn drives the second magnetic ring 420 to rotate. The second magnetic ring 420 then drives the input end of the torque detection mechanism 200 to rotate, and the torque detection mechanism 200 performs real-time torque detection. Compared to the existing torque detectors, which cannot move dynamically during the detection process and are not suitable for torque detection procedures of magnetic transmission structures, the coupling dynamic torque tester provided in this embodiment uses a moving mechanism 300 that can change position during the detection process to drive the second magnetic ring 420 to adjust its position. This allows the torque data provided by magnetic couplings 400 with different spacings to be detected and acquired in real time by the torque detection mechanism 200, eliminating the need for frequent disassembly and assembly and conveniently achieving dynamic torque detection.

[0038] like Figures 1-4 As shown, the torque detection mechanism 200 further includes a torque load 210, a torque sensor 220, a connecting shaft 230, and a first support frame 240. The first support frame 240 and the torque load 210 are sequentially arranged on the base 100. The torque sensor 220 is arranged on the first support frame 240. One end of the connecting shaft 230 is tightly connected to the second magnetic ring 420, and the other end of the connecting shaft 230 is tightly connected to the torque load 210. The torque sensor 220 is rotatably connected to the middle position of the connecting shaft 230.

[0039] In this embodiment, the torque load 210 includes a mounting shell 211, a display unit 212, and a torque assembly 213. The mounting shell 211 is disposed on the base 100, the display unit 212 is disposed on the base 100, and the torque assembly 213 is rotatably connected to the side wall of the mounting shell 211. The torque assembly 213 is a 63KG torque assembly. The drive shaft of the torque assembly 213 passes through the side wall of the mounting shell 211 and is connected to the torque sensor 220. When the drive shaft rotates, the torque sensor 220 can detect the current torque parameter of the drive shaft.

[0040] like Figures 1-4 As shown, the moving mechanism 300 further includes a guide rail 310, an adjustment component 320, and a moving seat 330. The guide rail 310 is disposed on the base 100, and the moving seat 330 is slidably connected to the guide rail 310. The output end of the adjustment component 320 is drivenly connected to the moving seat 330 and is used to drive the moving seat 330 to move along the length direction of the guide rail 310. The driving source 500 is disposed on the moving seat 330. The moving seat 330 includes a mounting frame 311 and a housing 312. The housing 312 is disposed on the mounting frame 311, and the mounting frame 311 is slidably connected to the guide rail 310. An output shaft 313 is rotatably connected to the housing 312, and the end of the output shaft 313 is tightly fitted to the first magnetic ring 410. Specifically, the guide rail 310, the output shaft 313, and the transmission shaft are arranged parallel to each other in their length directions. The movable seat 330 is provided with an inner cavity. The driving end of the drive source 500 and the end of the output shaft 313 are both located in the inner cavity. The other end of the output shaft 313 extends to the outside of the inner cavity and is tightly connected to the first magnetic ring 410. The driving end of the drive source 500 is driven connected to the part of the output shaft 313 located in the inner cavity.

[0041] like Figures 1-4As shown, further, there are two sets of guide rails 310, which are laid parallel and spaced apart on the base 100. The mounting frame 311 is L-shaped and slidably connected between the two sets of guide rails 310. The output end of the adjusting component 320 is drivenly connected to the vertical section of the mounting frame 311. Using two sets of guide rails 310 helps improve the movement stability of the moving seat 330, prevents the offset caused by mechanical vibration during dynamic torque detection from affecting the detection results, and improves the detection accuracy. In this embodiment, the vertical section of the moving seat 330 is fixedly connected to the outer wall of the moving seat 330 by pre-tightening screws. The output end of the adjusting component 320 is located between all the pre-tightening screws. Connecting the output end of the adjusting component 320 between the pre-tightening screws helps improve the connection stability between the adjusting component 320 and the moving seat 330.

[0042] like Figures 1-4 As shown, the adjustment assembly 320 further includes a fixed base 321, a handwheel 322, and a threaded rod 323. The fixed base 321 is disposed on the base 100 and located between the two sets of guide rails 310. A nut is provided on the fixed base 321, and the threaded rod 323 is threadedly connected to the nut. One end of the threaded rod 323 is rotatably connected to the vertical section of the mounting bracket 311, and the other end of the threaded rod 323 is tightly fitted to the handwheel 322. By rotating the handwheel 322, the user can drive the threaded rod 323 to rotate, thereby causing the housing 312 and the mounting bracket 311 to move along the linear direction of the threaded rod 323, thereby realizing the distance adjustment of the first magnetic ring 410 and the second magnetic ring 420.

[0043] like Figures 1-4 As shown, the drive source 500 further includes a reduction gear assembly 510, a transmission assembly 520, and a drive motor 530. The reduction gear assembly 510 is disposed at the output end of the moving mechanism 300, the output shaft 313 is disposed at the output end of the reduction gear assembly 510, and the output end of the drive motor 530 is drivenly connected to the input end of the reduction gear assembly 510. Specifically, the reduction gear assembly 510 is disposed in the inner cavity of the housing 312, and the transmission assembly 520 and the drive motor 530 are both disposed on the side wall of the housing 312.

[0044] like Figures 1-4As shown, further, the reduction assembly 510 is a planetary gear set, the housing 312 is disposed at the output end of the moving mechanism 300, the planetary gear set is rotatably connected to the housing 312, the transmission assembly 520 is disposed at the end of the housing 312 and is drivenly connected to the input end of the planetary gear set, and the output end of the drive motor 530 is drivenly connected to the input end of the transmission assembly 520. In this embodiment, the drive motor 530 is a servo motor. The transmission assembly 520 is a coupling.
