Problems solved by technology

This makes the energy loss of the impact drill 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 impact drill, and the wear of the carbon brush 07 produces carbon powder, which has caused certain pollution to the environment; There are many parts in the impact drill, and the transmission gears meshing 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 impact drill

Abstract

The invention discloses a percussion drill. The percussion drill comprises a case; a supporting part and a high power density brushless motor erected on the supporting part are arranged in the case; a controller of the high power density brushless motor is arranged in the case; the high power density brushless motor comprises a rotor shaft rotationally arranged in the supporting part; a chuck of the percussion drill is fixed at one end of the rotor shaft; an impact movable gear is arranged at the other end, far from the chuck, of the rotor shaft; and an impact static gear, arranged corresponding to the impact movable gear, is arranged in the case. According to the percussion drill provided by the invention, the service life of the percussion drill is prolonged; the generation of carbon powder is avoided, and environmental pollution is avoided; and a transmission apparatus arranged in the case is avoided, so that the service life of the percussion drill is prolonged, the energy consumption is reduced, the output efficiency is improved, the noise and the vibration are reduced, the trouble in engagement installation of the transmission gears is avoided, the volume and the weight of the percussion drill are effectively reduced, and convenience is brought for the assembling of the percussion drill.

Description

technical field [0001] The invention relates to the technical field of electric drill equipment, in particular to an impact drill. Background technique [0002] The impact drill is a kind of electric tool, and the fabric or other items to be polished are polished by the polishing disc of the impact drill. [0003] Please refer to figure 1 , figure 1 It is a structural schematic diagram of a percussion drill in the prior art. [0004] Wherein, the percussion drill consists of a casing 01, an output shaft 02, a chuck 06 arranged on the output shaft 02 and a motor with carbon brushes (comprising a rotor 03, a stator 04, a motor shaft 05 and a carbon brush 07). The end of the output shaft 02 away from the collet 06 is provided with an impact movable gear, and the casing 01 is provided with an impact static gear. The motor is set in the casing 01, the motor shaft 05 is a gear shaft or a gear is arranged at its end, so that it is meshed with the transmission gear, and then dri...
