Imprimir páginaAcraDyne® HT Nutrunning Systems deliver high amounts of torque to an application in a continuous drive manner. As is the
nature with all tool systems that function in this manner, high amounts of torque reaction will occur. AcraDyne® HT systems
work with Reaction Bars that engage the tool with a secure spline and when used correctly counteract the natural torque
reaction in use by pressing against a part detail or adjacent nut/bolt.
IT IS ESSENTIAL THAT THESE FORCES ARE UNDERSTOOD COMPLETELY BY THE OPERATOR AND
THAT THE REACTION BARS HAVE BEEN CHOSEN WITH THE APPLICATION'S SPECIFIC GEOMETRY
IN MIND.
ACRADYNE® OFFERS A RANGE OF REACTION BARS FROM STOCK AND WILL DESIGN SPECIFIC
REACTION BARS TO SUIT SPECIFIC APPLICATIONS UPON REQUEST.
IT IS THE USER'S RESPONSIBILITY TO ENSURE THAT THE CORRECT REACTION BAR OR TOOL
HOLDING FIXTURE IS IN PLACE PRIOR TO USE OF THE ACRADYNE® HT SERIES NUTRUNNER.
Reaction Bar Guidelines
CAUTION IS REQUIRED. FAILURE TO EXERCISE CAUTION AND CORRECT OPERATING TECHNIQUE
CAN RESULT IN SERIOUS PERSONAL INJURY, LOSS OF LIMB OR DEATH.
The guidelines offered below are only guidelines. Should there be any doubt as to the integrity of a proposed reaction strategy,
it is strongly advised to consult with an AcraDyne
Reaction force is equal to the point being applied. The magnitude of the reaction force is dependent upon the perpendicular
distance between the point of reaction and the centerline of the gearbox. In other words, the greater the distance the lower
force experienced. For this reason, the point of reaction should be kept as far away from the centerline of the tool gearbox as
possible.
Sockets
CAUTION IS REQUIRED. FAILURE TO EXERCISE CAUTION AND CORRECT OPERATING TECHNIQUE
CAN RESULT IN SERIOUS PERSONAL INJURY, LOSS OF LIMB OR DEATH.
ONLY IMPACT GRADE, INDUSTRIAL SOCKETS SHOULD BE USED WITH ACRADYNE® HT Series Nutrunners. Mechanic-grade chrome
sockets are not to be used as they do not have sufficient structural strength required to deliver the higher torque loads that an
AcraDyne® HT Series Nutrunner is capable of delivering. In addition, the use of Socket Extensions of any length are strongly
discouraged as they also will experience failure to an extent where tool damage or operator injury may occur.
