Description
Technical Field
The utility model relates to the technical field of handheld saws, in particular to a self-heat-dissipation type handheld saw.
Background
Hand-held saws, as one type of hand-operated tool, are often used to cut material.
However, when the heat is dissipated by the conventional handheld saw, the heat is dissipated naturally only through the heat dissipating port formed in the surface of the handheld saw, so that the heat dissipating efficiency is low, the internal driving assembly of the handheld saw is shut down due to overhigh temperature, and the service life of the handheld saw is affected.
Disclosure of Invention
The utility model aims to provide a self-heat-dissipation handheld saw, which is provided with turbine fan blades, a brake and a brake gasket, wherein the turbine fan blades, the brake and the brake gasket are sequentially and axially arranged along an output shaft of a motor, the turbine fan blades can remove dust and dissipate heat for the motor, and can dissipate heat efficiently for a brake structure.
In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a can be from handheld saw of heat dissipation formula, includes casing and motor, the fixed surface of motor output shaft is connected with turbine fan blade, the surface of casing seted up with the air intake that turbine fan blade position corresponds.
Optionally, the brake further comprises a brake and a brake washer arranged on the motor.
Optionally, the turbine fan blades, the brake and the brake washer are axially arranged in sequence along the output shaft of the motor.
Optionally, a saw blade is also included.
Optionally, the end of the output shaft of the motor is a helical gear shaft, and the helical gear shaft is in transmission connection with the saw blade through a helical gear.
Compared with the prior art, the utility model has the following beneficial effects:
according to the utility model, through the turbine fan blades, the brake and the brake gasket which are sequentially and axially arranged along the output shaft of the motor, the turbine fan blades can remove dust and dissipate heat for the motor, can efficiently dissipate heat for a brake structure, and is better in utility model.
The front end of the output shaft of the motor is designed into the helical gear shaft to be matched with the helical gear, so that the large torque can be effectively transmitted although the rotating speed is reduced, the energy-saving and efficient effects are achieved, the transmission structure is simple, and the production cost is low.
