Abstract
A handheld electric power tool, in particular an angle grinder, having a housing that comprises a first housing part and a second housing part, having an electric motor that is accommodated in the housing and drives a rotor shaft that is connected in a force-transmitting manner to an output unit accommodated in a gear head. A housing ring is provided that connects the first housing part to the second housing part at the front.
Claims21
A handheld electric power tool comprising:
- a gear head that accommodates an output unit;
- a housing that comprises a first housing part and a second housing part, the first housing part and the second housing part being discrete, separate parts;
- an electric motor accommodated in the housing, the electric motor driving a rotor shaft that is connected in a force-transmitting manner to the output unit accommodated in the gear head;
- a housing ring that connects the first housing part to the second housing part at a front section of the housing;
- a guide for the electric motor, the quide being formed in the housing ring;
- and
- a motor housing for the motor, the motor housing being discrete from the quide,
- wherein the housing ring is screwed to the first housing part and/or the second housing part via a housing screw connection, and wherein the housing screw connection is made substantially parallel to the rotor shaft,
- wherein the housing is vibration-decoupled from the housing ring and/or the gear head,
- wherein on a side of the housing ring that faces away from the housing, the housing ring has an axial collar, on which at least one quide section for the gear head is formed,
- wherein the at least one guide section protrudes radially from the axial collar to align and center the gear head relative to the housing ring, and
- wherein the guide is formed as an annular axial rib that has a lead-in bevel on an inner circumferential side.
