20140230623 | REMOTE CUTTER HEAD AND SYSTEM - A remote cutter head and a system therefore which can operate in confined spaces are provided. The remote cutting system including a cutter assembly driven by a fluid source, a pushrod hose coupling the cutter assembly to the fluid source, a control assembly detachably secured to the pushrod hose, and a monitor assembly coupled to at least one camera. The monitor assembly provides video images of the cutter assembly and cutter assembly surroundings. The cutting head including a fluid-driven gearmotor, the gearmotor including a two-piece housing, bearings, a pressure balanced gearmotor cavity, and two rotating members provided in the pressure balanced gearmotor cavity, one of the rotating members protruding from the cutting head. High-pressure fluid provided to the cutting head turns the two rotating members to drive a cutting bit attached to the rotating member protruding from the cutting head. Also provided is a cutting bit. | 08-21-2014 |
20120294673 | ANGULARLY ADJUSTABLE CLAMP ASSEMBLY - An angularly adjustable clamp assembly includes a hub clamp, an adjustment base connectable to the hub clamp and a plurality of attachment members. The hub clamp includes a hub and collar, the hub having a sleeve portion forming a passageway to receive a shaft. The sleeve portion has multiple slits along the sleeve portion to form a plurality of sleeve segments. The collar has an inner surface configured to engage an outer surface of the sleeve portion. The attachment members cause the collar to move axially along the length of the sleeve portion to urge the sleeve segments radially inward to secure the shaft within the passageway. The assembly is configured such that at least one attachment member further connects the adjustment base to the hub clamp. The attachment members can be actuated to cause an angular adjustment of two shafts connected by the assembly. | 11-22-2012 |
20120141201 | HUB CLAMP ASSEMBLY - A hub clamp assembly is disclosed. The hub clamp assembly includes a hub that has a flange portion and an annular sleeve portion. The sleeve portion has a plurality of substantially longitudinal slits therein extending from a distal end toward the flange portion to form a plurality of sleeve segments. The sleeve portion further has an outer surface that includes a first set of surface features. The assembly also includes an annular collar that has one or more sleeve engagement pieces each having a first surface and an opposing second surface. The first surface of the sleeve engagement piece contains a second set of surface features configured to correspond to and engage the first set of surface features of the sleeve portion of the hub. A support ring surrounds the sleeve portion of the hub and overlies the second surface of the sleeve engagement pieces. | 06-07-2012 |
20120141199 | SHAFT CONNECTION ASSEMBLY - A shaft connection assembly for the transfer of torque between two shafts is disclosed. The assembly includes a hub and an elongated annular collar. The hub includes a flange portion and a sleeve portion, the sleeve portion having a plurality of sleeve segments formed by longitudinal cuts along the length of the sleeve portion such that when the collar is forced linearly, axially away from the flange portion, the sleeve segments exert a clamping force on each of two shafts disposed within a passageway formed by the hub. The clamping force prevents relative movement of the first shaft with respect to the second when the shafts are rotated about a common axis. A method for joining two shafts for the transfer of torque using the shaft connection assembly is also disclosed. | 06-07-2012 |
