ARMORED REPAIR-EVACUATION TRUCK Russian patent published in 1999 - IPC

FIELD: armored repair trucks. SUBSTANCE: the truck has a crane installed on the body by means of a bearing-rotary device with a gear ring, and a crane turning mechanism with a drive gear secured on the truck body. The turning mechanism output shaft is furnished with a pin engageable with the drive gear by means of a hollow spherical spacer with cylindrical lugs. The axes of the output shaft and cylindrical lugs are mutually perpendicular. The cylindrical lugs of the hollow spherical spacer are positioned in inserts installed in longitudinal grooves of the drive gear. Provision of a swing gear in the output shaft of the crane turning mechanism prevents jamming in the tooth pair without an additional strengthening of installation of the bearing-rotary device in the body. EFFECT: enhanced reliability of crane without any increase of mass of the truck. 2 cl, 3 dwg
