method for ASSEMBLing torsion coil tension-compression springs for resonant vibrational system as a trough Feeder

摘要

Method for connection of twisted helical tension-compression springs for resonance vibrating system as a trough feeder in which the ends of the springs arrange for mechanically joining to those the parts of vibrating system in the form of the trough feeder. The springs are made of a tubular blank by cutting it through with helical groove which does not reach the ends of the workpiece, with basing with supporting end and outer surfaces the end turns relative to the part of the vibrating system of the trough feeder. The springs are pairwise connected to the parts of vibrating system with clamping and based via cylindrical grooves and pins that go to these grooves. The cylindrical grooves are arranged at the end support surfaces of the end turns of springs of at least two on each support end surface, and the pins are placed in connection parts of vibrating system as a trough feeder. The last turns are bent and cut off so that at compression of the springs with flanges under the effect of the maximum load the spring turns do not touch each other.
