  • Publication number: 20140328640
    Abstract: A bi-metal drill bit includes a body defining a cutting end and a shank end. At least a portion of the cutting end is formed of a first metal section and at least a portion of the shank end is formed of a second metal section that is welded to the first metal section. The first metal section has a first metal having a material hardness that is higher than a second material hardness of the second metal section. One of the first and second metal sections is treated either by coating or oxide treating so as to have a recognizable different appearance than the other of the first and second metal sections. A length to diameter ratio of the first metal section has been optimized to allow electrical resistance welding, provide better strength in the rear end after the tip breaks through a workpiece, and to minimize cost.

  • Patent number: 8845203
    Abstract: A bearing assembly having improved impact Brinell resistance is provided. Due to a controlled gap between a rotating component and a non-rotating component or a vehicle suspension structure, the non-rotating component or the vehicle suspension structure is permitted to share impact loads caused by a sufficient side impact to the rotating component, thus preventing excessive loads from being transmitted to rolling elements, and providing greater resistance against Brinell impact damage that would generate a noise and/or vibration condition in the bearing assembly. The width of the controlled gap and of the area of potential contact between the rotating component and the vehicle suspension structure or the non-rotating component are optimized to increase impact Brinell resistance while avoiding excessive contact between the rotating component and the non-rotating component or the vehicle suspension structure during extreme cornering maneuvers.

  • Patent number: 8740515
    Abstract: A combination drill bit for use in both hand held drills and stationary drill presses has a shanking end, a working end and a helical flute portion between the shanking and working ends. The helical portion has a helix length (L) of L = ( D × ? tan ? ? ? ) . The drill bit has a core that is tapered from the working end to the shanking end. A web thickness length at the working end is 10% to 35% of the diameter and the thickness length at the junction of the shanking end is 70% to 90% of the diameter. The drill bit is manufactured from a high speed steel including at least 5% by weight of cobalt.

  • Publication number: 20120301238
    Abstract: A point chisel includes a substantially cylindrical shank and a working end region that tapers to a point. The working end region has at least three converging substantially planar surfaces, each with a protruding elongate rib extending along at least part of its length. Adjacent surfaces meet along at least part of their length at substantially straight edges between adjacent ribs. A flat chisel includes a substantially cylindrical shank and a working end region with a pair of converging substantially planar surfaces that include a plurality of protruding elongate ribs extending along at least part of its length. Each rib has, along the majority of its length, a substantially constant height above the surface from which it protrudes. Each chisel is made from steel, with the shank having a bainitic microstructure and the working end region having a martensitic microstructure.

  • Patent number: 8109183
    Abstract: An impact resistant tool or tool bit holder has an active end for driving a fastener and a shanking end for securing to a power tool. The active end includes a body with a bore to receive the shank and a pocket to receive a damping mechanism. The shank includes an end to engage the bore in the body, and a pocket to receive the damping mechanism. The shank is received in the bore in the body for limited rotation with respect to the body. A damping mechanism is positioned in the pockets to provide damping between the body and the shank during torque loading.

  • Patent number: 6993681
    Abstract: A method and system for remote administration of clients performing critical processes are disclosed herein. A client management module is used to monitor a subset of processes performed by a client. When the client management module detects that a process of the subset has terminated or become inoperable, the client management module can restart the process, as well as notify a remote system manager. Additionally, the client management module is adapted to monitor the consumption of system resources by one or more processes. Using fuzzy logic to evaluate the system resource consumptions of one or more system resource types, the client management module can select an appropriate action response to improve the performance of the process and/or notify an administrator of a status of the process. The remote system manager is adapted to monitor a connection with the client.

  • Patent number: 6979129
    Abstract: A self-lubricating connector or roller is formed by molding a laminated bearing insert in-situ within a nylon support or member. The connector provides a one-piece, self-lubricating device to replace conventional multiple-piece bearing assemblies which typically include a nylon member having an integral metallic sleeve rotatably engaged with a conventional needle or journal bearing. An alternate embodiment of the present invention includes a connector fabricated by press-fitting the laminated bearing insert into a member fabricated from a metallic material. The connectors or rollers of the present invention have several advantages over the prior art, including improved concentricity between the load bearing layer and roller, closer tolerances and elimination of parts and assembly steps.

  • Patent number: 6622377
    Abstract: A wheel bearing assembly for supporting a wheel and apportioned vehicle mass is provided. The assembly includes a spindle member defining a rotational axis with a flange for attaching a wheel and a hub assembly. A bearing assembly has inner and outer bearing members in spaced relationship from one another with a plurality of rolling members interposed between the bearing members to permit relative rotation between the bearing members about the rotational axis. The spindle is deformed around the inner bearing member to prevent axial translation between the spindle and the inner bearing member about the rotational axis. An outer surface of the inner bearing member has a geometric feature for receiving a force applied from a tool during the deformation of the spindle thereby reducing radial deflections of the inner bearing member during the process of deforming the spindle.
