Abstract
The invention relates to a reducer comprising a motor (1), a first-stage planetary gear (2) and a second-stage planetary gear (3), wherein the reducer further comprises a slave output mechanism, through which the reducer can still work when a master input shaft is damaged or rotate speed and torque need changing, the reducer can return to service just by installing the motor on the slave output mechanism without the need to replace the reducer, thereby saving manpower and resources greatly.
Description
Technical field
The present invention relates to a kind of rotation speed reducer, particularly a kind of dual input shaft speed reducer
Background technique
Planetary speed reducer is a kind of broad-spectrum industrial products, and its performance can compare favourably with other army's grade speed reducer product, and the price of technical grade product is but arranged, and is applied to the wide industrial occasion.
This retarder volume is little, in light weight, the bearing capacity height, long service life, running steadily, noise is low.Have power dividing, the private characteristic of multiple tooth engagement.Maximal input can reach 104kW.Be applicable to that industrial department planets such as lifting transportation, engineering machinery, metallurgy, mine, petrochemical industry, building machinery, industry light industry textile industry, medical apparatus, instrument and apparatus, automobile, boats and ships, weapons and Aero-Space series new varieties WGN ordinary transmission retarder, WN primary and secondary gear transmission retarder, elasticity all carry little tooth difference speed reducer.
Planetary speed reducer is a kind of new property speed reducer with extensive versatility, and internal gear adopts 20CvMnT carburizing and quenching and roll flute.It is little that complete machine has physical dimension, and output torque is big, and speed ratio is in characteristics such as, efficient height, performance be safe and reliable.This machine is mainly used in the swirl gear of tower crane, can be used as matching parts again and is used for industries such as lifting, excavation, transportation, building.
But traditional planetary speed reducer has only an input shaft at present, though its transmission efficiency is high, if long-time the use, because of its physical dimension is little, heat sinking function is poor, and its input shaft damages easily under particular surroundings.Traditional processing mode is to change a new planetary speed reducer, has caused the waste of manpower and materials.
Traditional in addition speed reducer generally is fixed rotating speed and moment of torsion, and the speed reducer volume with multiple rotating speed and moment of torsion is bigger, in practical operation, because the restriction of working environment can't be used the big more speed reducer of function of volume, so usually because need to change rotating speed, and have to change speed reducer, so just cause the waste of manpower and materials, reduced working efficiency, influenced job schedule.
Summary of the invention
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of having dual input shaft and can exporting the speed reducer of multiple rotating speed and moment of torsion of being easy to install and control is provided.
A kind of speed reducer comprises motor (1), primary planet pinion (2) and secondary planetary gear (3), and described speed reducer also has secondary output mechanism, described secondary planetary gear (3) band external toothing.
Described secondary output mechanism comprises auxiliary-motor (4), secondary primary planet pinion (5) and engaging gear (6), described engaging gear (6) and the engagement of described secondary planetary gear (3) external toothing.
The ring gear of described secondary planetary gear (3) is provided with for floating.
Described engaging gear (6) can slide vertically
Described engaging gear (6) has two kinds of gears, under normal circumstances, engaging gear (6) is in neutral gear, promptly be in clutch state with secondary planetary gear 3, the primary input axle damages or needs to change under the situation of rotating speed and moment of torsion, can adjust engaging gear (6) to the state of putting into gear, promptly be in engagement with secondary planetary gear 3.
The present invention has secondary output mechanism, damages or need at the primary input axle to start auxiliary-motor under the situation of replacing rotating speed and moment of torsion, slows down by secondary primary planet pinion 5, and engagement engaging gear 6 and secondary planetary gear 3 interlocks carry out double reduction and export.Under the situation that the primary input axle damages or need to change under the situation of rotating speed and moment of torsion, need not change speed reducer, only needing to install to secondary output mechanism to motor can come into operation again, has saved manpower and materials greatly.
Description of drawings
Fig. 1 is a structural representation of the present invention
Wherein
1 motor, 4 auxiliary-motors
2 primary planet pinions, 5 secondary primary planet pinions
3 secondary planetary gears, 6 engaging gears
Embodiment
As shown in the figure, the present invention includes main output mechanism and secondary output mechanism, under normal circumstances, can be by main output mechanism work, wherein main output mechanism comprises motor 1, primary planet pinion 2 and secondary planetary gear 3.
The input shaft of motor 1 is connected to primary planet pinion 2, carrying out one-level by primary planet pinion 2 slows down, the output shaft of primary planet pinion 2 is transferred to secondary planetary gear 3 then, carries out double reduction by secondary planetary gear 3 again, is transferred to output shaft output at last and rotates and moment of torsion.
Damage or need change under the situation of rotating speed and moment of torsion at the primary input axle, can be by secondary output mechanism work, wherein secondary output mechanism comprises the external tooth cover of auxiliary-motor 4, secondary primary planet pinion 5, engaging gear 6 and secondary planetary gear 3.
Adjust engaging gear 6 to the state of putting into gear, start auxiliary-motor 4, the output shaft of auxiliary-motor 4 is connected to secondary primary planet pinion 5, carrying out one-level by secondary primary planet pinion 5 slows down, the output shaft of secondary then primary planet pinion 5 is transferred to engaging gear 6, double reduction is carried out in the external tooth cover interlock of engaging gear 6 and secondary planetary gear 3, and the output shaft output that is transferred to secondary planetary gear 3 is at last rotated and moment of torsion.
Claims (4)
1. a speed reducer comprises motor (1), primary planet pinion (2) and secondary planetary gear (3), it is characterized in that described speed reducer also has secondary output mechanism, described secondary planetary gear (3) band external toothing.
2. speed reducer as claimed in claim 1 is characterized in that described secondary output mechanism comprises auxiliary-motor (4), secondary primary planet pinion (5) and engaging gear (6), described engaging gear (6) and the engagement of described secondary planetary gear (3) external toothing.
