Embodiment 1

[0030] See attached figure 1 , attached figure 2 And attached image 3 , the static weight type torque standard machine of the present invention comprises a support member 5, a standard force loading mechanism 1, a lever mechanism 2, a torque sensor installation part 3 and a control system 4 thereof;

[0031] The supporting part 5 includes a base plate 9, four uprights 8 and a mounting plate 7, the mounting plate 7 is fixed on the base plate 9 through the uprights 8, the bottom of the base plate 9 is in contact with the ground through the leveling feet 6, and the base plate 9 and the mounting plate 7 are installed horizontally; the main function is to carry the weight of the complete machine and provide support for installing the detected torque sensor 19.

[0032] The lever mechanism 2 includes a force arm 10, a lever leveling mechanism, a hinged part 11 and a fixed output shaft 18. The force arm 10 is a symmetrical structure, and a fixed output shaft 18 is arranged in the...

Embodiment 2

[0047] As a deadweight torque standard machine with a model of 10Nm, the standard machine is a verification device in which the torque generated by the standard weight is added to the torque sensor 19 under test. It consists of a supporting part 5, a standard force loading mechanism 1, a lever mechanism 2, a torque sensor installation part 3 and its control system 4.

[0048] The measurement range of this device is 0.1-10Nm. After analysis, it can be known that the trays of the weight loading mechanism on both sides can be divided into two layers. Each weight in the small weight carrying plate of the first layer generates a torque of 0.1Nm. Each weight in the multilayer weight bearing plate generates a torque of 1Nm, and can generate all torques from 0.1 to 10Nm by superposition.

[0049] The length of the force arm 10 of the device is 500mm. To generate a torque of 0.1Nm, a weight of 20g is required. To generate a torque of 1Nm, a weight of 200g is selected. However, because ...

Abstract

The invention belongs to the field of torque measuring and testing and provides a dead load type torque standardizing machine to solve the problems that in the prior art, the reliability is poor, the efficiency is low and verification cannot be achieved accurately and fast. The dead load type torque standardizing machine comprises a supporting component, a standard force loading mechanism, a lever mechanism, a torque sensor installing part and a control system of the torque sensor installing part. The standard force loading mechanism comprises a loading frame, a bracket mechanism and a disc loading mechanism, the output end of a stepping motor A penetrates through an upper installing disc, weights can be clamped or loosened through a clamping transmission mechanism and a clamping arm, and the upper ends of the weights penetrate through weight grooves in a lower installing disc. The control system is fixed on the lower portion of an installing plate, the standard force loading mechanism and the stepping motor of the bracket mechanism are controlled to rotate through the control system, and therefore the weights can be loaded and unloaded. The weights can be selected and combined at will to be used according to the verification demand of the torque sensor, a drive mechanism is simple, and reliability is high.
