- ツールを打撃軸線(A)に沿って打撃駆動する電動手工具装置において、
前記打撃軸線(A)に沿う打撃を生ずるため、偏心子(7)を有する打撃機構組立体(6)と、
この打撃機構組立体(6)を駆動する打撃機構伝動装置(8)であって、全体的に前記打撃軸線(A)の一方の側方側に位置する、該打撃機構伝動装置(8)と、
前記打撃機構伝動装置(8)を駆動するための電動モータ(2)であって、前記打撃軸線(A)に対して直交するロータ軸(3)を有する、該電動モータ(2)と、
ロータ金属片積層体(4)であって、全体的に前記打撃軸線(A)の前記一方の側方側とは反対側である他方の側方側に位置する、該ロータ金属片積層体(4)と、及び
前記ロータ軸(3)に支持したモータピニオン(5)であって、前記ロータ金属片積層体(4)とは離れた位置関係で、全体的に前記打撃軸線(A)の前記一方の側方側に位置して、前記打撃機構伝動装置(8)の一部をなす、該モータピニオン(5)と、
を備え、
前記打撃機構組立体(6)の質量系と前記電動モータ(2)の質量系とよりなる全体の質量系の重心(S)を、前記打撃軸線(A)上に位置する構成としたことを特徴とする電動手工具装置。 - 前記ロータ軸(3)を前記偏心子(7)のクランク軸(9)に近接配置し、打撃機構伝動装置(8)の一部としての偏心子ピニオン(10)をロータ軸(3)上のモータピニオン(5)に噛合させた請求項1記載の電動手工具装置。
- 電動モータ(2)の支持は、ロータ軸(3)を介して、打撃機構伝動装置(8)における2個の軸受部(11a,11b)において行い、これら2個の軸受部は、伝動装置ハウジング(12)及び軸受蓋(13)に設けた請求項1又は2記載の電動手工具装置。
- 前記ロータ軸(3)は、前記ロータ金属片積層体(4)を支持する部分では軸受されず軸線方向に自由に突出する部分として構成し、前記打撃軸線(A)に隣接するロータ金属片積層体(4)の端部でロータ軸(3)を軸受支持した請求項1乃至3のうちのいずれか一項に記載の電動手工具装置。
- 請求項1乃至4のうちのいずれか一項に記載の電動手工具装置において、さらに、送気ホイール(14)を設け、この送気ホイール(14)を、前記ロータ金属片積層体(4)の前記打撃軸線から遠い側の端面に隣接して、前記ロータ軸(3)の端部に配置した電動手工具装置。
- 前記電動モータ(2)をブラシレスモータとして構成した請求項1乃至5のうちのいずれか一項に記載の電動手工具装置。
