摘要： Example alignment systems for aligning a drill bit with respect to a gang channel and methods of use are described herein. An example alignment system for use with a drill includes a drill block having a guide portion and an attachment portion. The attachment portion is configured to be removably coupled to a foot of the drill such that the drill block is positioned between the foot and a drill bit of the drill. A longitudinal axis of the drill block is coaxial with a longitudinal axis of the drill bit when the attachment portion is coupled to the foot. The guide portion is configured to at least partially contact an inner surface of opposing legs of a gang channel to thereby center the drill bit between the opposing legs of the gang channel.

摘要： A tool with a transmission assembly having a reduction gearset and a speed selector. The speed selector has a member, an actuator and a shifter assembly. The member is movable between a first position, in which the member is non-rotatable, and a second position in which the member is coupled to a planet carrier of the reduction gearset for common rotation. The actuator includes a pivoting yoke and a follower that is coupled to the yoke. The follower engages the member so as to be axially movable with the follower. The shifter assembly has a selector switch, a switch fork, and a pair of springs. The selector switch is slidable between a first switch position and a second switch position. The switch fork is slidably coupled to the selector switch and receives the yoke. The springs cooperate to bias the switch fork relative to the selector switch into a neutral position.

摘要： A brushless motor includes a stator and a rotor installed in the stator. The stator includes a front insulating frame and a rear insulating frame. The rotor includes a rotating shaft, a front bearing, a rear bearing, a front-end cover and a rear-end cover. The front-end cover is located on the front side of the rotor and installed on the front bearing. The rear-end cover is located on the rear side of the rotor and is installed on the rear bearing and abuts against the rear insulating frame. The front side of the front insulating frame is provided with multiple first snap parts. The front-end cover is provided with multiple second snap parts in the circumference. The first snap parts are snap-fitted with the second snap parts.

摘要： A flexible shaft, having a first end and, a second end and capable of being bent about its axis while transferring rotary motion from a device to tool is disclosed. The shaft, manufactured from a rigid material, has at least one flexible segment having two sinuous slots ascending in a helical path from a common start point in opposite rotational directions. In other segments the slots can be a single helical slot, double helical slots, parallel or crossing, or circumferential. The helical paths can vary within each segment or from segment to segment.

摘要： The invention relates to a boring machine comprising a spindle (15) which is designed for rotationally driving a boring tool that is placed or can be placed on the spindle and which is paired together with rotational drive means that interact with a first drive motor (24) for rotational driving purposes and with adjustment drive means that interact with a second drive motor (26) for axially adjusting the spindle such that when the spindle is being rotated by the first drive motor, the spindle can be axially adjusted under the effect of the second drive motor. The rotational drive means have a rotational drive gear (38) which is connected to the spindle, and the adjustment drive means have an adjustment nut (58) which interacts with a threaded section (60) of the spindle (15) in the manner of a slide. Transmission means are integrated in the form of a transmission module for interacting with the rotational drive gear and the adjustment nut and are designed to connect to the first and the second drive motor. The transmission means have an adjustment gear (54) for meshing into a toothing of the adjustment nut (58), said adjustment gear being driven by a toothed gear assembly (46, 42) which engages onto an outer toothing (52) of the adjustment gear such that at least one first toothed gear (42a-c) of the toothed gear assembly receives a drive torque of the second drive motor, in particular the at least one first toothed gear interacts directly with a drive shaft (30) of the second drive motor (24, 24A), and at least one second toothed gear (46a-c, 46′a-c) of the toothed gear assembly transmits a drive torque of the first toothed gear (26, 26k) to the outer toothing (52), in particular the at least one second toothed gear meshes directly with the first toothed gear and the outer toothing. The toothed gear assembly is held in a cage-like toothed gear support (44) such that at least the second toothed gear, preferably the first and the second toothed gear, can be released from the transmission module and replaced when disassembling the adjustment gear and/or a module which drives the rotational drive gear, in particular a toothed gear unit.
