Embodiment Construction
[0047] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.
[0048] The cylindrical hollow belt diaphragm flexible hinge type flexible hinge mechanism adopted by the present invention is divided into three parts: the outer layer, the inner layer and the transverse partition. The outer layer is divided into two parts: the outer layer A part 1 and the outer layer B part 2. These two parts have the same inner diameter and outer diameter. These two parts are coaxial. The outer layer A part 1 and the outer layer B part 2 are the mechanism The two ends of the bod...

The invention discloses a motor torque measuring method based on a flexible hinge. The motor output torque is measured through a cylindrical hollow flexible hinge-shaped flexible hinge mechanism with a horizontal partition. An outer layer of the flexible hinge mechanism comprises an outer layer A and an outer part B; an inner layer of the flexible hinge mechanism comprises an inner layer A and an inner layer B; the inner layer A and the outer layer B are blended within the range of the outer layer B; the inner layer B and the outer layer A are mutually blended within the range of the outer layer A; the inner layer A and the inner layer B are connected together through a first horizontal partition and a second horizontal partition; the first horizontal partition and the second horizontal partition are mutually vertical in space; a first strain gauge and a second strain gauge are respectively pasted in the centers of the two faces of the first horizontal partition; a third strain gauge and a fourth strain gauge are respectively pasted in the centers of the two faces of the second horizontal partition; when the motor torque measuring device and the motor torque measuring method based on the flexible hinge are used, the motor output torque can be conveniently calculated by detecting the change of the output voltage and combining known parameters.
Description
technical field [0001] The invention relates to a method for measuring motor torque, in particular to a method for measuring motor output torque through a cylindrical hollow belt diaphragm flexible hinge mechanism, and in particular to a device and method for measuring motor torque based on a flexible hinge. Background technique [0002] The so-called flexible hinge mechanism refers to a special kinematic pair form formed by using the micro-deformation and self-recovery characteristics of elastic materials under the action of external force or moment. The flexible hinge is a typical flexible mechanism, which has many advantages compared with the traditional rigid hinge mechanism: [0003] 1. It eliminates the idle motion and mechanical friction in the transmission process, and can obtain ultra-high displacement resolution; [0004] 2. Simple structure, small size, light weight, and can save a lot of assembly work; [0005] 3. No friction and wear, long life; [0006] 4. N...
