Patent attributes
A pneumatically driven deburring device having a housing and a pneumatic motor mounted therein which is adapted to receive and drive a deburring tool. A pivot bearing is mounted within the housing adjacent the pneumatic motor. A motor support is held within the pivot bearing and extends therefrom where the motor support connects to the pneumatic motor. An air inlet is disposed adjacent the pivot bearing and is communicatively connected thereto. Air for driving the pneumatic motor is directed through the air inlet, and through a hollow portion of the motor support to where air is directed into the pneumatic motor. Because the motor support is supported or contained within the pivot bearing, it follows that the motor support articulates with the pivot bearing and hence the pneumatic motor moves with the articulating motor support.
