Mechanical transmission security device for load e.g. vehicle, transporting wagon`s reducer, has screw spindle with sliding gear comprising driving bolt permitting to temporarily suppress irreversibility function of reducer

摘要

#CMT# #/CMT# The device has a screw spindle (9) mounted in a plane parallel to shafts (7, 8) that are fixed in walls of a case and rotated between the walls of the case. The spindle has a sliding gear, a fixed anti-friction ring (11) and a floating anti-friction ring, where the rings assure static braking of the spindle so that a reducer is in irreversible functioning situation. A driving bolt provided in the gear drives the spindle so that the spindle is shifted and detached from a needle thrust bearing (16) in forming a clearance that is sufficient to temporarily suppress irreversibility function. #CMT#USE : #/CMT# Used for a reducer that is associated with a winch for controlled and secured lowering of fixed lower and mobile upper platforms of a wagon which is utilized for transporting load e.g. vehicle. #CMT#ADVANTAGE : #/CMT# The security device acts punctually and temporarily on components of the reducer for assuring the disconnection of the sliding gear in original manner in order to suspend the operation time of maneuvering of the load. The irreversibility function assures all the stability and security for the installation in which the device is preserved. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a partial cross sectional view of a security device. 7, 8 : Shafts 9 : Screw spindle 11 : Fixed antifriction ring 16 : Needle thrust bearing 27 : Caging bolt.
