Clock spring - Technical information
The spring is best assembled on a grooved shaft. The end of the groove should be milled or rounded. To prevent the spring from getting an eccentric shape, leading to friction during load, the outer end should be fixed as shown in one of the above examples. Otherwise, both torque force and spring life will be compromised.
For a static load (Nc < 10 000), the highest torque angle shown in the table is recommended. The table also shows the approximative torque angle for 100 000 oscillations. If a higher Nc is required, please contact us for information about permitted torques.
