METHOD FOR ARREST OF SHAFT STOPPED IN ARBITRARY POSITION, AND DEVICE FOR ITS REALISATION Russian patent published in 2009 - IPC F16B1/00 F16D71/00 

FIELD: machine building.

SUBSTANCE: invention is related to machine building and may be used in machines and mechanisms for arrest of shaft stopped in arbitrary positional location. According to method for shaft arrest connecting gears are fixed to shaft parallel to each other, and these gears have common outlet link and identical transfer functions at free rotation of shaft, and in case of shaft arrest transfer function of one of mechanisms is changed, as a result, outlet link, and therefore shaft as well, can not move. Device for realisation of mentioned method consists of two parallel transfer kinematic chains with identical transfer functions, every of which consists of serially joined hinged four-terminal network and rocker-slider mechanism, inlet links of which are put in motion from shaft subject to arrest, and outlet link slider is common, crank mechanism installed parallel to hinged four-terminal networks so that slide block has common axis of rotation with outlet links of hinged four-terminal networks, and its inlet link - rocker performs combined motion with inlet links of hinged four-terminal networks. Mechanism link is guiding for outlet link - slider. In one of kinematic chains there are kinematic pairs of links that make it possible for connecting rod and outlet link of hinged four-terminal network and connecting rod of crank-slider mechanism to rotate around link for variation of transfer function of this kinematic chain.

EFFECT: provision of stopless shaft arrest without application of additional external forces.
