Dynamic calibration needs will be calibrated axis and be installed on dynamometer machine, apply certain torque to axis by dynamometer machine and record
Resistance variations caused by corresponding foil gauge deformation realize calibration, but vehicle propeller shaft length, thickness in the market is all different,
If to make tooling every time using Bench calibration or need to be processed axis, change, the period of high cost is long.
Torque flange refers to a bit of axis demarcated, and when use need to cut off measured axis, and torque flange is connect
Enter, due to having destructiveness to axis and needing to make the torque flange of different-diameter for the axis of different-diameter, cost is high.Cause
This both methods is only applicable to the calibration of experimental study axis or production axis, is driven for acquiring vehicle, complete machine in the market
Operability is poor for axis torque.
Utility model content
In order to overcome the problems, such as the use limitation of dynamic calibration and torque flange technology and complicated for operation of high cost, this reality
It is to provide a kind of axis torque calibrating table with novel purpose.
The utility model realizes that the scheme of purpose is as follows：A kind of axis torque calibrating table, it is characterised in that：The calibrating table packet
Operation console, movable plate, axis, flange, support element, counterweight cantilever are included, described operation console one end is equipped with movable plate, and the movable plate is equipped with set
Hole, the operation console other end are equipped with support element, and the flange is one end of the axis and flanged joint, another by supports support
One end passes through the movable plate sets of holes and fixation, and the counterweight cantilever is fixed on flange, and the axis is equipped with foil gauge.
Preferably；The flange is connect by fixture I with one end of axis, and the other end of the axis passes through the movable plate sets of holes
And it is fixed by fixture II.
Preferably；The flange is equipped with counter-jib, the central axis of the counterweight cantilever and the central axis of counter-jib
In the same horizontal line, the counterweight cantilever and counter-jib is identical in quality.
Preferably；The operation console is equipped with sliding slot, and the movable plate can be slided along sliding slot.
Preferably；The support element is fixed board, and the fixed board is equipped with sets of holes, and bearing is equipped in the fixed board sets of holes, described
Flange passes through bearing.
Preferably；The fixed board is 2 pieces, and the counterweight cantilever and counter-jib are set between two pieces of fixed boards.
Preferably；The support element is supported for the edge of a knife.
The advantages of the utility model：
（1）The utility model provides a kind of static shaft torque calibrating device, avoids dynamic calibration to engine pedestal
With the requirement of motor, easy to operate, use cost is low；
（2）The movable plate of fixing axle can be slided along sliding slot, applied widely suitable for the axis of various length and diameters, general
Property is strong, when demarcating different axis, without additionally making tooling, and it is easy for installation；
（3）The utility model can avoid the flexural deformations that its entirety generates axis after counterweight cantilever drape counterweight, and can
Make one end of axis have rotary freedom, ensure that the accuracy of calibration；
（4）The counter-jib of the utility model can counterpoise cantilever gravity, eliminate counterweight cantilever own wt and cause
Axis torque, make axis be solely subjected to Weight gravity application torque, make calibration more accurate, calculating process is simpler.
