Abstract
A vibration attenuated power drill is disclosed. The drill comprises a housing incorporating a motor (6) for driving an output shaft. A drill bit is driven by the output shaft by means of cooperating ratchet plates contained in a gearbox. The motor has a stator (24) and a rotor (26), and is provided with vibration attenuating means comprising leaf springs (38) attenuating vibrations transmitted from the motor to the housing along the axis of rotation of the rotor (26) relative to the stator (24).
Claims21
A power tool comprising:—
- a housing;
- a motor within the housing for actuating a working member of the tool, the motor having a stator and a rotor adapted to rotate about a first axis relative to said stator;
- and
- first vibration attenuating means for attenuating vibrations transmitted from said stator to said housing at least in a direction substantially parallel to said first axis.
A tool according to any one of the preceding claims, further comprising resilient second vibration attenuating means for attenuating vibrations along three orthogonal axes transmitted from a working member of said tool to said housing.
A power tool substantially as hereinbefore described with reference to the accompanying drawings.
