Motor parallel transmission portable angle grinder

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.

Benefits of technology

[0009]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. Aside from a manually controlled electromechanical device, a power storing and discharging device is also installed in the handle for use as a power source.

Problems solved by technology

Because the above structure necessitates an angle type transmission device, the resulting very loud noise is the deficiency.
