Helical torsion spring torque test
The solution
- BOB体育最新下载安装Mecmesin any software to control the torque tester
- EmperorTM rotate the spring to the predetermined Angle, torque and angular displacement data collected in a row.
benefits
- To measure the stiffness or the spring stiffness, in order to ensure the correct design specifications.
- Through software control and match with spring sample custom fixture, realized the high degree of repeatability
requirements
Spring loaded components widely used in household and consumer goods: clothes pin, clip and old mousetrap;A camera or small door on the hi-fi equipment and flap;Large door and closing device, such as a garage or on the door and close the door, and in transportation applications (such as the trunk)
Although known as "reverse" and running under the load torque, but when the spring end shaft rotates around its center, the spring itself will be affected by the bending stress, this is the connection on either arm (or leg) driven components.
In use need to rotate the component parts of depends largely on the spring stiffness level.
This will determine whether this component is suitable for the purpose, and shows the correct resistance levels, in order to facilitate operation and obtain high quality feeling.
The solution
Controlled by the software of electric testing will spring rotation to scheduled Angle, and continuously collecting the torque and Angle displacement data.
This software can ensure repeat test in clockwise or counterclockwise direction, and to prevent permanent deformation spring materials.
From below and above the load point closer to its target, and then to carry on the average, in order to maximize reduce friction and hysteresis of contact between the spring coil as a result of the influence.
"Pass/fail" which the operator can through clear instructions immediately see located within the specified torque limit requirements (when rotating in the area of the linear elastic spring).
In precision applications using minimum torsion spring, under the friction of the coil can be very important.
An urgent need to adopt a kind of test system, the system can not only ensure the axis of the spring in the strict tolerance range alignment, and can accurately measure the torque value of the very light.
Test equipment
- With appropriate nominal sensor Vortex or Helixa torque test system.
- EmperorTM fully programmable torque testing software.
- Custom design of the core and shaft match the spiral geometry.
