COMBINED SPRING WITH TORSIONAL DAMPER Russian patent published in 2018 - IPC F16F3/10 F16F7/01 F16F13/02 F16F1/14 

FIELD: engineering.

SUBSTANCE: invention relates to mechanical engineering. Combined spring contains a cylindrical helical spring consisting of two parts with oppositely directed ends. Mounting rings are provided on the inactive coils. First spring part is fitted with turns of rectangular section and rounded edges and second part is made hollow. On-coming end of first part is located in cavity of second part. Gaps of segment profile of contacting spring parts are filled with antifriction grease. Sealing gasket is mounted at end of second spring part to prevent grease leakage. First part of the spring is covered by a tube of damping material. Gaps in the first part of the spring, which covers the tube of damping material, are filled with friction material crumb. On the upper and lower support rings vibration damping plates are fixed, consisting of alternating layers of resilient and vibration damping materials.

EFFECT: increased efficiency of vibration isolation in resonance mode is being achieved.
