TRANSMISSION WITH SAFETY SWITCH Russian patent published in 2015 - IPC F16H1/16 F16H55/22 H01H3/16 

FIELD: machine building.

SUBSTANCE: switch contains a platform (1), with fixedly secured switch (2) and supports (3, 4), in which with possibility of rotation an axle (5) is installed, on it shaft (6) is installed, it has diameter larger than axle diameter. On the shaft one coiled spring (7) is secured and envelopes it, spring ends (8) can contact with limiters of axial movement and switch, having possibility of engagement with wheel (9) secured on the coupling axle (10). At that the shaft (6) can have possibility of movement along the axis (5) that shall be made with splines, or made at one with axle (5). In this case the axle has the possibility of axial movement in the supports, at that engine shall be connected with axle such that does not prevent the said movement, i.e. is connected, for example, by means of splines. On the shaft between the turns of the first spring (7) the second spring (11) can be secured. The support can be made in form of the radial or radial-thrust bearing (12), its internal ring is fixedly connected with axle (5), and has possibility to interact with spring end.

EFFECT: simplified design and improved reliability.
