Embodiment 1

[0006] Example 1: Refer to the accompanying drawings. The driving part of this embodiment includes a servo motor and a transmission, which can effectively reduce the problems of overshoot and control instability. The high-precision servo motor is directly connected to the transmission to provide a rotational speed source for the entire device.

Embodiment 2

[0007] Example 2: refer to the accompanying drawings. This embodiment adopts a photoelectric sensor and a virtual instrument composed of a signal acquisition card and a computer. The rotational speed signal output by the coupling shaft head is collected and fed back to the computer control system, and then the driving part is controlled by the computer control system to achieve the rotational speed required for detection and solve the rotational speed measurement problem of the entire device.

Embodiment 3

[0008] Example 3: refer to the accompanying drawings. This embodiment is completely computer controlled. Including computer and central controller two parts. Using the powerful data and information processing functions of the computer, the central controller controls the entire device, combined with the specially developed detection software, so as to realize the functions required by the present invention.

Abstract

The invention relates to the technical filed of measurement and value transfer, in particular to a measuring table( A level) for the rotation speed characteristic of a torque rotation speed measuring device which measures the rotation speed characteristic of various torque rotation speed measuring devices( B level). The rotating speed and the certain position are accurately controlled through a computer and a digital servo system. The invention has the advantages of increasing the accuracy and precision of the measurement and the reliability of the measured data by utilizing various Windows application programs, avoiding the uncertain discreteness of the system, decreasing the errors caused by a manual operation, and favoring the research on the torque measurement.

Description

[Technical field] [0001] The invention relates to the technical field of metrology testing and value transmission, in particular to a torque and rotational speed measuring device rotational speed characteristic testing platform (first-class standard) for verifying the rotational speed characteristics of various types of torque and rotational speed measuring devices (secondary standards). standard). [Background technique] [0002] At present, flexible couplings are used to replace universal joints when testing the speed characteristics of torque and speed measuring devices to meet the requirements of high speed and radial offset. Each testing department lacks special stepless speed regulation driving equipment, and has not put forward requirements on the speed fluctuation and connection coaxiality of the stepless speed regulating driving device. Some testing departments only take the on-site dragging equipment as the criterion, and cannot assess the influence of the dragging...
