Marble cutting machine

Abstract

The invention discloses a marble cutting machine comprising a housing (7) and a motor casing (1) arranged in the housing (7) and fixed on the side wall of the housing (7); a high power density brushless motor is arranged in the motor casing (1), and a controller (5) thereof is arranged in the housing (7); the high power density brushless motor comprises a rotor shaft (2) arranged in the motor casing (1) in a rotary manner; the rotor shaft (2) is coaxially arranged with a drive shaft of a marble cutting blade (6) of the marble cutting machine so as to form an integrated structure; the axis of the rotor shaft (2) is perpendicular to the plane on which the marble cutting blade (6) is located, and penetrates the center of the marble cutting blade (5). The marble cutting machine can prevent carbon dust generation and environment pollution, can improve life and reduce energy cost, can improve output efficiency and reduce noises and vibration, can prevent transmission gear engagement installation complexity, can reduce size and weight, and the marble cutting machine can be conveniently assembled.

Description

technical field [0001] The invention relates to the technical field of electric saw equipment, in particular to a marble cutting machine. Background technique [0002] The marble cutting machine is an electric tool, and the fabric or other items to be polished pass through the polishing disc of the marble cutting machine to complete the polishing effect. [0003] Please refer to figure 1 , figure 1 It is a structural schematic diagram of a marble cutting machine in the prior art. [0004] Among them, the marble cutting machine consists of a casing 01, an output shaft 02, a transmission gear 08 arranged on the output shaft 02, a marble cutting piece 06 arranged at the end of the output shaft 02, and a motor with carbon brushes (including the stator 03, Rotor 04, motor shaft 05 and carbon brush 07) form. The motor is set in the casing 01, the motor shaft 05 is a gear shaft or a gear is set at its end, so that the output shaft 02 and the motor shaft 05 are meshed through th...

AI Technical Summary

Problems solved by technology

This makes the energy loss of the marble cutting machine large, reducing the output efficiency of the tool, and the wear of the carbon brush 07 and the transmission gear directly affects the service life of the marble cutting machine, and the wear of the carbon brush 07 produces carbon powder, which is harmful to the environment. There are many parts in the marble cutting machine, and the transmission gears that mesh with each other will inevitably produce large noise and vibration during the power transmission process, and it is not convenient for the assembly of the marble cutting machine
