Abstract
The invention discloses a double output electric drill, which comprises an electric drill casing, a motor arranged in the electric drill casing, a motor output shaft arranged at the front end of the motor and a double output gear drive, which is characterized in that two output shafts with same axis line are arranged on the double output gear drive; the planetary gears on the double output gear drive are slide-fitted with an axis line fixed on the planet carrier, wherein the axis line is fixedly connected with the electric drill casing; the planetary gears match with an inner gearing shaft on the outside, wherein the inner gearing shaft is pressured into the bearing inner ring of the gearbox and slide fitted with a porous bearing; the inner gearing shaft and the porous bearing are pressured into the gearbox casing of the double output gear drive; the gearbox casing is fixedly connected with the electric drill casing through screws. The double output electric drill has the advantages that two output shafts output while rotating in opposite directions according to a certain reduction ratio, thereby the drilling efficiency is improved and is suitable for multifunctional drilling and complex assembly.
Description
Technical field
The present invention relates to electric drill, the twin-output electric driller that rotates by certain speed reducing ratio in the time of particularly a kind of brand new in the other direction.
Background technology
At present, the new electric drill of releasing mostly is single shaft output on the market, and the synchronization folk prescription is to the common electric drill that rotates, and it comprises motor, electric drill housing, gear-box, electric drill chuck, motor switch control device.Motor output shaft rotates by the drill bit on the gear-box deceleration electric drill chuck, realizes the drilling to object.This electric drill function singleness, drilling efficiency is low, can not satisfy the needs of multi-functional drilling and complicated assembling.
Summary of the invention
The objective of the invention is to overcome existing electric drill single shaft output, function singleness can not satisfy deficiencies such as multi-functional drilling and complicated assembling demand, and a kind of dual output structure in the other direction brand-new the time is provided, the drilling efficiency height can satisfy multi-functional drilling and the complicated electric drill that assembles.
The present invention solves the problems of the technologies described above, and the technical scheme that is adopted is:
A kind of twin-output electric driller comprises the electric drill shell, is positioned at the motor of electric drill shell, the input gear that is positioned at the motor output shaft of motor front end, is connected by spline with motor output shaft, and dual output gear drive.The described dual output gear drive of motor-driven, it is characterized in that: described double-output transmission device has the output shaft of two coaxial inner conductors, the output shaft of described two coaxial inner conductors is respectively internal gear power transmission shaft and motor output shaft, and two output shafts are connected with the drill bit of outside; Mandrel fixing on the planetary gear of this double-output transmission device and the planet carrier is slidingly matched, and described mandrel is fixedlyed connected with the electric drill shell; Described planetary gear cooperates with the internal gear power transmission shaft of outside, and the internal gear power transmission shaft is pressed into the box bearing inner ring and is slidingly matched with oiliness bearing; Described bearing and oiliness bearing are pressed into the gearbox-case of dual output gear drive; Described gearbox-case is fixedlyed connected with the electric drill shell by screw.
Relate to the design of twin-output electric driller, applicable to the various forms of electric drill: it mainly is to drive double-output transmission device by motor by motor output shaft, and double-output transmission device has two output shafts, and two output shafts are connected with the drill bit of outside respectively.The electric motor starting of twin-output electric driller, the input gear drive planetary gear that is connected with the motor output shaft spline fitted rotates, and planetary gear rotates, and drives the internal gear power transmission shaft and forces to rotate output simultaneously in the other direction according to a certain percentage.
