PROPELLER SHAFT PROTECTIVE DEVICE

摘要

FIELD: agricultural engineering; applied mechanics. ^ SUBSTANCE: invention relates to safety engineering devices of general application. Proposed protective device of propeller shaft contains protective sleeve installed coaxially to shafts of drive and actuating machines and consisting of three tubular members. Protective device contains electric clutch connecting drive and driven shafts whose housing is rigidly coupled with driven shaft. Housing of electric clutch accommodates driven friction disks and driving frication disks coupled with splined shank of drive shaft for longitudinal displacement along splined slots. Ring contact projection is found on outer surface of electric clutch housing. Said contact projection engages with brush secured on first tubular member coupled by wires with electric starting system of drive machine engine. Magnet is installed flush with outer side of second tubular member which engages with sealed contact reed relay installed in hole of third tubular member. Sealed contact reed relay is coupled by wires with engine electric starting system. ^ EFFECT: improved safety of operating personnel and simplified design of device. ^ 3 dwg
