Embodiment Construction

[0014] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0015] This embodiment is a torsional stiffness adjustment device, which includes a sub-end plate 2 , a female end plate 1 and multiple sets of flexible rods 3 . The sub-end plate 2 is in the shape of a truncated cone, with a circular boss 5 processed in the middle and a card slot 4 processed in the axial direction around it. The female end plate 1 is also in the shape of a circular frustum, and there are card slots 4 processed around it corresponding to the sub-end plate 2. The size and number of the card slots 4 are the same as those of the sub-end plate 2. There is an annular boss 7 processed in the middle, and the middle part of the annular boss 7 is processed. Circular groove6.

[0016] The number of flexible rods 3 is the same as the draw-in groove 4 on the same child and female end plates in cross-sectional shape.

[0017] When in use...

Abstract

The invention relates to the field of mechanical drive, and especially relates to the field of carrying out designing and testing on mechanical drive systems. The invention discloses a torsional rigidity adjusting device which comprises a daughter end plate (2), a mother end plate (1) is arranged parallel to flexible rods (3), the daughter end plate (2) is arranged parallel to the mother end plate (1), a boss (5) of the daughter end plate (2) partially extends to the inside of a groove (6) in the middle of an annular boss (7) of the mother end plate, the boss (5) and the groove (6) are mutually coaxially matched so as to ensure that the daughter end plate (2) and the mother end plate (1) can rotate coaxially, the flexible rods (3) are fixed in corresponding clamp slots (4) of the daughter end plate (2) and the mother end plate (1), and the flexible rods are parallelly arranged in pairs. Through changing the installing number and type of the flexible rod (3), the torsional rigidity adjustment can be achieved; the torsional rigidity adjusting device is simple, reliable, easy to process, and convenient to use and operate; the function of the torsional rigidity adjusting device is realized easily, and the torsional rigidity adjusting device is small and exquisite in volume; and the torsional rigidity adjusting device can be applied to various environments, thereby improving the designing and testing efficiencies, simplifying the operation process, reducing the testing cost, and shortening the designing and testing periods.

Description

technical field [0001] The invention relates to the field of mechanical transmission, in particular to the field of design and testing of a mechanical transmission system. Background technique [0002] In modern design and testing, problems are often encountered regarding the torque transmission of the system and the adjustment of its torsional stiffness. Torsion springs or torsion tubes are usually used in engineering. Torsion springs are generally standard parts. The volume and torsional stiffness cannot be changed. The torsional stiffness can only be adjusted by replacing the torsion spring or connecting multiple sets of torsion springs in series. The installation space is tight and the replacement process is cumbersome. ; Torque tubes are generally system components, and their design, calibration and replacement require a lot of manpower and material resources, and a long cycle. Such design methods are not advocated in the design. Especially in the engineering design an...
