Title: Indicator for replacement times of dampers - esp dampers for angular oscillations as used on combustion engines
Inventor: TONNDORF JOCHEN DIPL ING
IPC: F16F15/24
Filed: 1974-07-24
Abstract: The amount of wear of a damper which damps out angular oscillations during rotation of combustion marine engines depends on the time the engine is used in the area of the critical speeds corresponding with resonance frequencies. The viscous dampers used with silicone oil are further also affected by the temperatures achieved druing runs at critical speeds. To indicate the time after which a damper should be replaced, a contact arrangement is used in which a first contact is made when a critical speed is reached. This contact switches on a counter timer (5). A delay componponent (6) can be introduced between contact and timer, so that the timer is not switched on if the engineer only runs for a short period at a critical speed.
