Embodiment Construction

[0039] The hand-held corner grinder of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments of the present invention.

[0040] The present invention is a hand-held angle grinder with parallel transmission of the motor. The rotating shaft of the motor rotating part is arranged parallel to the position adjacent to the rotating shaft of the grinding wheel, and the grinding wheel is driven by a parallel transmission device. Noise, and / or set the inertial body in the motor rotation to form a flywheel function to improve the grinding and cutting or cutting ability of the grinding wheel, and / or make the motor open or semi-closed to lead to the casing and / or to the handle In order to improve the external heat dissipation effect inside the motor; besides the manual control electromechanical device on the grip handle, when using the storage and discharge device as the power supply, the storage and discharge device c...

Abstract

The present invention relates to a motor parallel transmission portable angle grinder with a motor rotating part spindle parallel installed in a position adjacent to a grinding wheel spindle to form a parallel transmission device driving the grinding wheel. By means of the parallel transmission device, the present invention prevents the emission of noise made by angle type transmission devices; and / or an inertial body is installed on the motor rotating part to form a flywheel to improve the grinding, polishing and machining or cutting abilities of the grinding wheel; and / or a motor is established to be open or semi-hermetic for the space from the interior to a housing and / or a handle of the motor to improve the effect of heat dissipation outward.

Description

technical field [0001] The invention relates to a hand-held angle grinder, in particular to a hand-held angle grinder with a motor driven in parallel. Background technique [0002] The traditional motor-driven hand-held right-angle grinder is an electric tool designed according to ergonomics, and its structure is as follows: [0003] (1) The axial direction of the grip handle extended by the casing and the axial direction of the grinding wheel have an angle difference of 30° to 150°; [0004] (2) The electric motor is arranged in the grip handle; [0005] (3) There is a corner-type transmission device between the grinding wheel shaft and the motor shaft arranged on the grip handle, such as a bevel-shaped angular gear set. [0006] Because the above-mentioned structure must have the angular transmission device, the noise is too large for its lack. Contents of the invention [0007] In view of this, the main purpose of the present invention is to provide a hand-held angle...
