Safeguard system of a speed increasing/reducing mechanical assembly, especially of the helicopter "gear box" type, in case of lubricating oil loss
First Claim
1. Safeguard system of a speed increasing/reducing mechanical assembly in case of lubricating oil loss, characterized by the fact it contains an additional cooling system of the casing of said mechanical assembly, with an inlet and an outlet arranged on the casing of this mechanical assembly, which are closed during normal operation and that open under the action of a control device at a preset value of a parameter significant for the lubricating oil loss, this control device actuating simultaneously the additional cooling system in order to provide a circulation of the coolant between the inlet and the outlet, so that this coolant, loaded with the calories further to the warm-up caused by the lubricating oil loss, may evacuate the calories via the outlet of the additional cooling system.

Abstract
The invention relates to a safeguard system for speed increasing/reducing mechanical assembly, especially of the helicopter "gear box" type, in case of lubricating oil loss, which comprises an additional cooling system the casing of the said mechanical assembly, with an inlet (1) and an outlet (2) arranged on the casing (3) of this mechanical assembly. The inlet (1) and the outlet (2) closed during normal operation and they open under the effect of a control device at a preset value of a parameter significant for lubricating oil loss, whereby this control device actuates simultaneously the additional cooling system, in order to provide a circulation of the coolant between the inlet (1) and the outlet (2) so that this coolant, loaded with the calories further to the warm-up caused by the lubricating oil loss, may evacuate the said calories outside via the outlet (2) of the additional cooling system, which is of the air circulation type.

17. Safeguard system of a speed increasing/reducing mechanical assembly in case of lubricating oil loss comprising an additional cooling system connected to a casing of the mechanical assembly including normally closed inlet means for inletting additional coolant to the casing, normally closed outlet means for providing circulation of the coolant from said inlet means through the casing and for evacuating the coolant carrying excess heat caused by lubricating oil loss out of the casing, and control means for opening said inlet means and said outlet means at a preset value of a parameter significant for the lubricating oil loss.
