摘要： A dust collection system for a circular saw having a saw housing and a motor configured to rotationally drive a saw blade includes a dust collecting member and a guide mechanism. The dust collecting member includes a body having a first end in which a dust collection opening is defined and a second end operably connectable to an airflow generation device. The guide mechanism is configured to support the dust collecting member on the saw housing such that the dust collection opening remains adjacent to an outer edge of the saw blade in response to one of the dust collecting member and the guide mechanism contacting the workpiece to move the dust collecting member.

摘要： A power tools incorporates a brushless or electronically commutated drive motor (BLDC). A number of drive trains are provided for connecting the BLDC to the drive shaft of a working tool, such as a rotary saw blade. In one aspect, the BLDC motor is disposed within an arm assembly of a power tool and provides power to the drive shaft of the tool through a gear train that minimizes the size and profile of the power tool.

摘要： A guard device for a saw system in which the table saw is not operated without a saw blade guard, unless a user intends to make a non-through cut in a workpiece. The guard device, in one embodiment, determines whether an adjusted saw blade height corresponds to a thickness of the work piece to be cut and prevents the tool or motor driving the saw blade from operating if the saw blade is adjusted too high, in order to improve work conditions.

摘要： The invention relates to a toothed wheel of a gear drive, particularly for electric hand machine tools, comprising a toothing and a damping element made of an elastic material, the element being disposed in a recess of the toothed wheel. The object of the invention is to improve the effectiveness and the operational safety of the damping element on a toothed wheel with little effort in order to increase the service life of the gear drive. The task is solved by the toothed wheel (1) having a recess (5) penetrating the toothing (2).

摘要： The invention relates to a tool holding fixture for an insert tool (14), which comprises a substantially discoid hub (42), especially for a hand-operated angle grinder (32) or a hand-held circular saw. Said tool holding fixture comprises catch device (12) comprising a leaf spring unit (58), by means of which a catch device the insert tool (14) can be tensioned in the axial direction (64). The inventive tool holding fixture is characterized in that the leaf spring unit (58) has at least one free spring bar (110) that extends at least partially in the peripheral direction (50, 52).

摘要： The invention relates to a hand-guided jig saw machine (10) comprising a jig saw blade (33) which can be detachably clamped between two essentially parallel limbs (221, 222), at the free ends thereof, and which can be driven, especially in a reciprocative manner, by a motor (11) that is integrated in the jig saw (10). Said limbs are preferably constructed of a U-shaped frame (22), especially having a tubular shape. A transversally projecting handle (13) comprising a switch button (15) of an on-off switch is arranged on the free end of one of the limbs (221, 222). A light, compact and cost-efficient hand-guided jig saw machine can be produced by virtue of the fact that the lower limb (221) supports, especially in a base housing (12), both the motor (11) and the transmission means (114, 115, 116, 119, 67) which effect the reciprocative motion of the saw blade (33), whereby a motor shaft (1103) is coupled to a crankshaft (116) in a manner that is parallel to the limb (221). Said crankshaft is coupled via a connecting rod (67) to a flexible abutment (51, 57) for clamping the saw blade (33).

摘要： The invention relates to an electric portable power tool for a discoid rotating implement (18). The power tool comprises a power tool housing (11), out of which a drive spindle (12) for the implement (18) projects and on which a hollow cylindrical chuck collar (15) is formed that is coaxial to the drive spindle (12). The power tool also comprises a protective cover (20), which is detachably mounted on the power tool housing (11), provided for at least partially covering the implement (18), and which can be placed on and fixed to the chuck collar (15) by means of a clamp (23) having a tightening element (24). In order to place the protective cover (20) in desired positions of rotation relative to the power tool housing (11) without the use of an auxiliary tool and to secure the protective cover (20) in any set position of rotation, the clamp (23) is held on the chuck collar (15) in a manner that enables it to rotate, and a manually releasable locking is formed between the clamp (23) and the chuck collar (15).
