Hand-held electric power tool e.g. percussion drill - has vibration decoupling of handgrip from motor by using rubber mounts between inner motor casing and outer tool casing

摘要

The power tool has its drive enclosed in a motor casing (11). A gear casing is fixed to the motor casing. The motor casing is enclosed in an outer casing (12) via vibration dampers - i.e. via a vibration-decoupling arrangement. The outer casing envelops the motor casing at a distance and is mounted on it via rubber-like components (14). The outer casing is centred and prevented from rotating relative to the motor casing by guides (13). The power tool's handgrip (12') is on the outer casing not on the motor casing. The motor casing has holders for the guides and components (13,14). Centering parts (31) are provided at the rear of the casings. USE/ADVANTAGE - Percussion drill. Effective vibration decoupling of handgrip.
