The difference between the elastic coefficient of a tension spring and a torsion spring

Date of release:2019-04-18 00:00:00 Author: Click:

Torsion hardware spring testing machine pro-t series, is the automatic determination of torsion spring Angle ←→ load, load ←→ torsion high-performance testing machine, can play a high efficiency, laborsaving torsion spring inspection function.




At present, the testing of torsion spring samples is based on JISC's pro-t series, which is recognized by the world. JISC (Japan) industry level 5 standard is strictly implemented, and the testing performance is stable, convenient and accurate.




I. special functions:


1. Functions:


Torsion hardware spring testing machine pro-t series, is the automatic determination of torsion spring Angle ←→ load, load ←→ torsion high-performance testing machine, can play a high efficiency, laborsaving torsion spring inspection function.




2. Features:


1) it is easy to operate, and all kinds of determination conditions can be set.




2) according to the dimension input of the drawing surface of the hardware spring, the positions of the X-axis and Y-axis loadbars and rotary bars can be calculated.




3) in the screen, the test results and the set values are clear at a glance.




4) the range of load measurement can be switched automatically.




5) torque value and load value are represented to switch.




6) there are three units gf, KGF and N(Newton) to choose from.




7) there are also three units of torque length, mm, cm and m, which can be switched.




8) any torque, load and Angle can be reset from zero.




9) it can perform 10 degree, 1 degree and 0.1 degree inching rotation each time.




10) internal keys are equipped with past load stop and non-stop devices.




11) can print out the index number, measurement Angle, torque value, load value, elastic coefficient, free Angle.




12) can print out the average of the data obtained from the previous test and the reply test.




13) the printing method can choose load value, torque value, two units and remember to print.




14) perform the calculation and presentation of the most suitable guide rod.




15) selection of center Angle and outer peripheral Angle and the representation of Angle can be implemented.




16) the electronic calipers of the x-y mobile platform can be expressed on the operation panel.


In general, two objects described by K are not the same, that is, they have different units, just like generalized coordinates, which have different units for different objects.




Tension spring K=EA/L (where E is the modulus of elasticity, A is the cross-sectional area, and L is the length)




Torsion spring K=GIp/L (where G is the shear modulus, Ip is the moment of inertia of the cross section to the centoid, and L is the length)
