Power drivers are commonly used in production to tighten fasteners such as nuts and bolts. The socket which engages the fastener is normally coupled to the drive shaft of the power driver by a square male end on the drive shaft and a complementary square female connector on the socket. These components are not produced to close tolerances and as a result there is substantial play permitting misalignment of the rotational axes of the drive shaft and the socket and some rotational freedom between the drive shaft and the socket. In accordance with the invention an anti-vibration adaptor is provided comprising a sleeve containing a cylinder of resilient material which surrounds a portion of the drive shaft and a portion of the socket, including the point of coupling, sufficiently closely to minimize misalignment of the rotational axes of the drive shaft and the socket and reduce rotational freedom.
An anti-vibration adaptor for use in association with a rotary driving means including a drive shaft having a cylindrical portion and an axis of rotation and an associated fastener driving device having a cylindrical portion and an axis of rotation coupled to said drive shaft to provide rotary motion to said driving device about its axis of rotation by means of a non-cylindrical releasable coupling said adaptor comprising:
An anti-vibration adaptor as claimed in 1 wherein said fastener driving device comprises an extension shaft and a socket.
An anti-vibration adaptor as claimed in 1 wherein said damping means surrounds said drive shaft and said fastener driving device sufficiently tightly as to produce a slip fit.
An anti-vibration adaptor as claimed in 1 wherein said damping means is formed from a high molecular weight polystyrene.
An anti-vibration adaptor as claimed in 1 wherein said housing is a hollow cylinder.
An anti-vibration adaptor as claimed in 1 wherein said housing is a hollow cylinder formed from at least one of steel, stainless steel, aluminum, cast iron, copper, brass, titanium, fibreglass, carbon fibre composites and plastics.
An anti-vibration adaptor for use in association with a rotary driver having a drive shaft, at least a portion of which is cylindrical, having an axis of rotation, with a square driving end and a socket, at least a portion of which is cylindrical, having an axis of rotation, releasably coupled to said drive shaft by a complementary square female drive connector said adaptor comprising:
An anti-vibration adaptor for use in association with a rotary driving means including a drive shaft, at least a portion of which is cylindrical and has an axis of rotation and an associated fastener driving device, at least a portion of which is cylindrical and has an axis of rotation, coupled to said drive shaft by means of a releasable coupling said adaptor comprising:
An anti-vibration adaptor for use in association with a rotary driver having a drive shaft with a square driving end and a socket releasably coupled to said drive shaft by a complementary square female drive connector said adaptor comprising:
