摘要： A drill includes a housing and a motor coupled to an output member by a transmission. The transmission can selectively couple the output member to an output spindle through a low speed output gear or a high speed output gear for rotating the output spindle at a first speed or a second speed, respectively. Alternatively or additionally, a low speed mode can be provided by actuating an electronic switch that limits the speed of the motor. A rotatably fixed hammer member and a rotatable hammer member can be mounted around the output spindle. A mode collar can be rotatably mounted on the, housing and around the output member for movement to positions that correspond to various mode of operation, including a low speed mode, a high speed mode, and a hammer-drilling mode. In the hammer-drilling mode, the transmission operates in the high speed mode.

摘要： A drill housing supports an output spindle comprising a material that is relatively soft. The non-rotating hammer member can be mounted around the output spindle, adjacent its forward end, and adjacent the relatively soft material of the drill housing. The non-rotating hammer member can include support slots located along its edge. Support rods that are made of a relatively hard material can extend through the support slots to support the non-rotating hammer member. A plurality of recesses can be provided in the relatively soft material of the drill housing to support the non-rotating hammer member. A hammer mode shift mechanism can be configured to move the non-rotating hammer member along the support rods between a first position corresponding to a non-hammer mode and a second position corresponding to a hammer mode. The relatively hard support rods support the non-rotating hammer member to thereby resist damage to the relatively soft material of the housing member.

摘要： A drill includes a housing with a motor coupled to an output spindle via a transmission. A mode collar can be rotatably mounted on the housing for movement that corresponds to different modes of operation. The mode collar can be coupled to an electronic switch to operate a movable member thereof. The coupling can include a switch housing including a slide member, an actuation spring member and a return spring member. The mode collar can have a cam surface and a cam follower in the form of a shift pin that moves the slide member, causing actuation of the switch. The actuation spring member provides a biasing force that is sufficient to overcome a biasing force of a switch spring member to move the movable member into the actuated position. The mode collar can also enable and disable contact between a fixed hammer member and a movable hammer member mounted around the output spindle.

摘要： The present invention is directed toward a shield assembly for a handheld tool device such as an angle grinder. The shield assembly is selectively repositionable with respect to the cutting tool. A lock mechanism secures the shield assembly in discrete rotational positions relative to the cutting tool. The shield assembly includes a guard member and a bumper member, and an alignment feature configured to align the relative positions of guard member and the bumper member, thereby positing the members in a predetermined relative orientation. With this configuration, the shield assembly is selectively repositionable via a “hands-free” mechanism that permits a user to adjust the position of the shield assembly by simply contacting the shield assembly against a work surface.

摘要： The present invention is directed to an airflow generation and particle dispersion arrangement for a power tool (e.g., an angle grinder). The arrangement includes a motor, an airflow generation assembly, and a particle dispersion assembly. The airflow generation assembly includes a fan driven by the motor. When engaged, the driven fan generates an airstream that is drawn through the power tool. The particle dispersion assembly includes a passive fan that is not driven by the motor, but instead is driven by the airstream. In operation, the passive fan generates centrifugal and mechanical forces sufficient to remove particles from intake air passing through the particle dispersion assembly.

摘要： A multi-mode drill can include a transmission to transfer torque from an output member of a motor to an output spindle. A transmission housing encloses the transmission in an interior cavity formed by a gear case shell and a cover plate. The cover plate can be coupled to the outer shell via screws. A static shift rod can be supported at one end by the cover plate. A shift bracket can be mounted on the shift rod and biased to a mode position by a biasing member exerting a force between the shift bracket and the cover plate. A shift pin can be supported adjacent one end by the cover plate and biased to a mode position by a biasing member exerting a force between the shift pin and the cover plate. A spindle biasing member can bias the output spindle against the cover plate. The shift pin can actuate an electronic switch. A motor housing can be coupled to the transmission housing with fasteners so that the cover fasteners are not accessible.

The input shaft may support chuck jaws. A chuck actuating shaft may be mounted for rotation on the input shaft. The power take off mechanism may be connected to the tool chuck. The power take off mechanism may be adjustable into a DRILL DRIVE MODE to rotationally drive the input shaft and the chuck actuating shaft together as a unit, and a CHUCK MODE to use the transmission shaft to rotationally drive the chuck actuating shaft relative to the input shaft. The transmission shaft may be a gear shaft axially aligned with the input shaft, or a tertiary shaft axially offset from the input shaft.
