摘要： A power tool having a plastics material housing and a power output spindle is provided with a tube-like metal member in the front end of the housing. A bearing is received within the tube-like member for supporting the spindle. The tube-like member has at the front end thereof radially outwardly extending tabs for dissipating heat therefrom. The tabs are preferably partially embedded in the plastics material of the front end of the housing for anchoring the member therein, alternate tabs preferably being angled rearwardly. The member may also support ratchet teeth of a hammer drill. A fan may be mounted on the spindle in the region of the front end of the member for facilitating dissipation of heat from the radial tabs.

摘要： A hammer drill for manually guided operation includes an electric drive motor, a tool spindle and a pneumatic hammer function. The hammer drill includes a pressure piston, a striker, and a beat piece for striking axially against a tool that is held by the tool spindle. When the striker reaches a forward limit position, an end section thereof protrudes into a retaining ring that is aligned coaxially with the spindle axis. Manufacturing quality can be improved by bracing the retaining ring against an annular collar in the tool spindle on the one side and axially against a locking ring set in an annular groove conformed in the tool spindle via a retaining disc on the other side. The retaining ring, the retaining disc and the non-return disc are each mirror-symmetrical.

摘要： A hammer includes a jacket having an inner chamber; an inlet circuit for the entry of compressed air, and an outlet circuit for the exit of compressed air. The hammer includes a motion mechanism, for generating vibratory motion under the action of compressed air; and a punch or beater, connected to the motion mechanism, for contacting the casting to be de-cored, forming a first end of the hammer. The hammer has a measurement circuit measuring the oscillation frequency of the motion circuit. The measurement circuit includes a sensor for measuring the oscillation frequency of the motion circuit; a processing circuit, enclosed in a protective casing, for receiving electric signals transmitted by the sensor, and a communication line for conducting electric signals from and/or to the measurement circuit. The jacket includes a housing formed in the outer surface of the jacket, such that it incorporating the measurement circuit protective casing.

摘要： A hammer includes a handle, a head portion, and a striking mechanism. The head portion is connected with the handle and includes a metal strike element and a resilient strike element. A receiving space is defined between the two strike elements. The striking mechanism is located in the receiving space and includes a slide axle and a striking member. The striking member has a through hole for being slidably sleeved onto the slide axle. The striking member is slidable in the receiving space to alternatively strike one end of the head portion. Thereby, inertia striking force is provided by the striking member so that the hammer can be used to strike an object more easily.
