1 Scope

This test system table is applicable to the verification and value transfer of torque measuring instruments. It specifies the use of the torque national standard Pathway, a metrological parameter of the reference and a procedure for transmitting a torque unit quantity to the working measuring instrument by means of a metering standard, and Indicate its uncertainty and basic standard methods. It can also be used as a basis for traceability when performing calibration.

2 measuring reference equipment

2.1 Torque National Standard The torque national standard mainly undertakes the work of recurring, preserving and transmitting the torque value, and is the unified national torque value. The highest basis. According to the current situation in China, they consist of three static weight torque bases of 50Nm, 1kNm and 5kNm. The composition of the machine, the main technical data is shown in Table 1. Table 1 Main technical data of torque reference machine Baseline Torque Expansion Uncertainty (k=3) Torque Value Range/Nm Minimum Torque/Nm 50Nm 0.01% 0.5~55 0.5 1kNm 0.01% 10~1090 10 5kNm 0.01% 50~5450 50 The static weight torque reference machine uses the weight of the weight as the standard load, and the standard torque is generated by the action of the force arm lever. Moment, with the appropriate mechanism, automatically, smoothly and accurately apply the working moment and the balancing moment to the inspected in a predetermined order The torque standard machine on the torque meter. Each benchmark has two sets of large and small weights, which are divided into left and right sides of the lever. It can generate torque with equal torque values in both directions, positive and negative. The metrology performance of such a torque machine depends on the force value Uncertainty, uncertainty of the arm, etc. The former mainly depends on the quality of the weight, the acceleration of gravity at the installation site, Uncertainty in measurement of density and air density of weights, as well as loading and unloading methods, mechanical structure and quality stability of weights Wait. The latter mainly depends on the measurement uncertainty of the length of the lever and the construction of the lever, the support structure, and the horizontal control process. Degree is also closely related to coaxiality, processing technology, installation quality and so on. The reproducibility of the torque reference is mainly traced to the mass, length, and time basic quantities. Can use the component method, pass no Deterministic analysis and evaluation, and calculate its extended uncertainty. At the same time, in order to ensure that the benchmark torque value is consistent with the international Sex, the benchmark should regularly participate in relevant international comparisons.

3 measuring standard appliances

Torque standards can be divided into two categories throughout the torque calibration system. The first type is to generate (or reproduce) the torque value. Fixed standard. At present, the static-weight structure standard machine is mainly used, and some machines with larger ranges adopt the lever type knot. Structure, there are some standard devices for other structural principles. The second category is a variety of portable standards that transmit torque values. this The class standard can be divided into a dial gauge type, a strain gauge torque meter and the like according to the measurement principle.
