摘要： A motor driven hammer is described comprising a housing (3), a motor (9) having a motor shaft (11) and being arranged in the housing (3), a hammer mechanism including a cylinder (17) in which a ram (23) is arranged the ram being slidable along a longitudinal axis (L) of the cylinder (17), and a tool holder (15) which may support a tool bit so that the tool bit is aligned with the longitudinal axis (L) of the cylinder (17), wherein the motor (9) is coupled with the hammer mechanism, so that rotation of the motor shaft (11) results in a reciprocating movement of the ram (23) within the cylinder (17), the ram (23) applying impacts on a tool bit supported by the tool holder (15) during the reciprocating movement. Further, the ram (23) is made of a paramagnetic or ferromagnetic material or comprises a permanent magnet and a coil (47) is arranged within the housing (3) adjacent to the cylinder (17) so that the coil (37) applies a force in the direction of the longitudinal axis (L) on the ram (23) if a current is applied to the coil (47).

摘要： A drill includes a housing and a motor having a drive spindle. An output spindle is capable of being rotationally driven by the drive spindle via a torque clutch. The drill further includes atangential impact mechanism for superimposing tangential impacts onto the output spindle when activated. The tangential impact mechanism includes a sleeve rotatably mounted on the output spindle, and an anvil rotatably mounted onto the output spindle. The output spindle and the sleeve are rotationally driven by a planetary gear system comprising a ring gear, a sun gear and a planetary gear which is drivingly connected between the ring gear and sun gear.

摘要： A rotary hammer incorporating both a reciprocating drive for generating a first hammering action transmittable to a tool bit and ratcheting mechanism for generating a second hammering action transmittable to the tool bit. The first hammering action and the second hammering actions differing in frequency and force of the impacts transmitted to the tool bit. Furthermore, the reciprocating drive and ratcheting mechanism are selectably engageable so that the first hammering action and the second hammering action may be selectably transmitted to the tool bit individually or in combination depending on the desired mode operation.

摘要： A hammer drill with rolling contact at the contact surfaces for transmission of axial force between a drive shaft and hammer shaft. In the case of ball bearings, point contact is obtained. In the case of roller bearings, line contact is obtained. The area of contact is thus close to zero as opposed to a relatively large area in engagement systems using toothed surfaces. Use of point or line contact reduces heat generation and reduces energy loss due to friction.
摘要翻译：一种在接触表面滚动接触的锤钻，用于在驱动轴和锤轴之间传递轴向力。在球轴承的情况下，获得点接触。在滚子轴承的情况下，获得线接触。因此，接触面积接近于零，与使用齿形表面的接合系统中相对较大的区域相反。点或线接触的使用减少了发热，并减少了由于摩擦而导致的能量损失。

摘要： A mallet is described that has at least one cleft, in such a structure that the stress wave created during impact has longer travel way than the length of the mallet as measured along the impact line. This mallet induces longer-lasting and weaker stress wave(s) in the anvil as compared to a solid mallet having the same outer dimensions and more or less the same weight. The Cleft-Mallet increases the effectiveness of the strike, while decreasing the stresses in the anvil.
