Abstract
The utility model relates to an internal radiating electric chain saw with a handle being able to heat, which is hand-held electric cutting tool used for transversely cutting the articles of timbers, plastics, etc. A motor of the tool adopts a hollow rotor shaft on the basis of conventional external radiating miniature motors and is additionally provided with an internal radiating system. The overload capability of the motor is enhanced; the weight of the motor is reduced. Simultaneously, the radiating system also provides a heat source for heating a handle. The tool has a saw chain lubricating system, and is capable of ensuring the normal work of a high-speed cutting mechanism.
Description
The utility model is the hand electric cutting machine tool in order to article such as transversal timber, plastics.
The motor internal heat of existing electric chain saw must conduct through the metal of shell and fin, dispel the heat along two kinds of heat transfer types such as forced ventilation convection current of case surface.Because heat can not directly distribute, radiating rate is slow, influences the raising of overload capacity.And because of the electric motor starting electric current is big, in the operation of Fraquent start, accelerated the temperature rise of motor, reduced the real output of motor.In addition, exist also that complete machine weight is big, chain speed and stock-removing efficiency is low, lack disadvantages such as necessary labor safety devices, lubrication state be not good.
The purpose of this utility model is for overcoming above-mentioned shortcoming, provide a kind of in heat dissipation type, overload capacity big, have saw chain lubricating arrangement, a heatable electric chain saw of handgrip.
The utility model is realized as follows.
After the energising, the gear end of the hollow rotor shafts of rotation, through the reduction gearing of reducing gear, the drive sprocket of cutting mechanism drives saw chain and carries out cutting operation.For reducing the running resistance of saw chain, in the service life of improving cutting mechanism, set up manual saw chain lubrication device.
Fan on the hollow rotor shafts, the negative pressure that its rotation is produced makes the cold air that enters fan guard, and a part is discharged through the motor outside heat sink, and a part flows through through axial hole, radial hole, valve and tracheae, gas path control valve, the auxiliary-handle of hollow rotor shafts.Make the foliated rotor balancing post of centrifugal fan, the air that has improved motor internal flows and the forced ventilation effect, makes it on the basis of the outside heat radiation of conventional micro-machine, has realized the internal heat dissipating of motor again.Simultaneously, gas path control valve can be shifted one's position as required, makes the hot gas in the motor make it heat or directly discharge in the time need not heating by auxiliary-handle.
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is the general assembly front view of electric chain saw; Accompanying drawing 2 is general assembly side views of electric chain saw.
With reference to accompanying drawing, the motor I is by the stator that is fixed on the housing, one end mill become gear hollow rotor shafts 3 and on cage rotor 16, fan 2, fan guard 1, cast from the motor radiating sheet in the stator case outside, motor drive end bearing bracket, and compositions such as sealing, rolling bearing supporting arrangement.
The reducing gear II is an one-level garden stud wheel decelerator, and the drive sprocket 12 of cutting mechanism is installed on the reduction gearing output shaft 11.
The manipulation of electric chain saw, by main handle 17, the power switch 18 on auxiliary-handle 4 and the main handle, gas path control valve 8 realizations such as grade on the auxiliary-handle 4.Power supply lead-in cable 20 places in the main handle cavity, and two ends are connected with motor stator lead-out wire 19, attaching plug 21 respectively.
The motor radiating system is made up of outer heat radiation and two systems of interior heat radiation.During work, the rotation of fan 2 forms the negative pressure of motor internal on the hollow rotor shafts 3, make air enter the garden shape hollow rotor shafts air inlet on the fan guard 1 and be auxilliary and penetrate that shape is arranged and after the air inlet two ends are the outer heat radiation air inlet of half garden shape, a part is along motor housing duct discharge through between the motor radiating sheet on every side, another part cold air is through axial hole, the radial hole of hollow rotor shafts 3, valve 5,7 and tracheae 6, gas port on the auxiliary-handle support 10, gas path control valve 8, auxiliary-handle 4 is directly taken the heat of motor internal out of.Simultaneously, the hollow rotor shafts radial hole is pressed sub-multiple angle and is distributed, and each hole is not in same planar alignment.Make the foliated rotor balancing post 15 of centrifugal fan, further strengthened ventilation effect, formed the inner forced ventilation heat loss through convection of the distinctive micro-machine of the utility model mode.
The temperature adjustment of auxiliary-handle 4 is realized by gas path control valve 8 and adjustment screw 9.When gas path control valve and valve 7 connections, the motor internal heat makes its heating through auxiliary-handle 4, realizes warming.During summer, unclamp adjustment screw 9, the gas path control valve 8 that moves to left makes the heat in the motor directly discharge without auxiliary-handle.
