Abstract
A kind of double star wheel reducers.The present invention is the recreation to planet-gear speed reducer, the planetary gear of row wheel star wheel reducer is become twin-stage from single-stage by him, level-one in double pinions is still meshed with the fixed annulus in traditional structure, another grade is meshed with a rotatable internal gear, this rotatable internal gear is the output end of speed reducer, and output shaft is arranged thereon.The two-stage of the double pinions internal gear different from two is meshed, and forms two groups of drive connections, when the engaged transmission of two groups of planetary gears and internal gear than it is identical when, rotatable internal gear does not rotate as the internal gear of fixation, i.e.,;The speed ratio of speed reducer is infinity at this time, when the transmission ratio difference of two groups of planetary gears and internal gear, can be rotated internal gear and just rotates, adjust the ratio between two groups of teeth wheel set transmission ratio, can obtain different speed reducer speed ratios.Output end can also not have to internal gear, and use the make of the driven sun gear at the center that is placed in.
Description
Technical field
The present invention relates to a kind of mechanical gearing speed reducers.
Background technique
Existing speed reducer is many kinds of, and transmission ratio that is different and lifting, but have is limited, such as cylindrical gear reducer;Have
Though have a higher speed ratio mechanical efficiency is not high, such as worm-gear speed reducer, and then there is dimension in cycloidal planetary gear speed reducer
The disadvantages of repairing difficulty is not suitable for high power transmission as harmonic wave speed reducing machine again, the advantages of because of a kind of the invention collection existing speed reducer,
The speed reducer for overcoming its insufficient brand new class has become the needs of technology development.
Summary of the invention
Illustrate technical solution of the present invention with Fig. 1 first: by 4 institute of the body element 1 with internal tooth and cover member
In the casing of composition, right end device has the output shaft member 3 with internal tooth, the internal gear segments and body element 1 of the output shaft
Inner gear portion split-phase by simultaneously, the planetary gear frame member 5 in this outer cage occupies most of space, in planetary wheel carrier part 5
On have it is several with planetary gear center be in radiation symmetric distribution double pinions parts 2, in the level-one of the two-stage gear and position
Sun gear member 6 in casing center is meshed, and outside is then meshed with the internal gear on casing, double pinions it is another
Level-one is then meshed with the output shaft member 3 with internal tooth, the level-one and machine of such sun gear member 6 and double-pinion planetary gear member 2
Internal gear three in main body element 1 forms one group of drive connection;And another grade of twin-stage gear member 2 and the internal tooth of output shaft
Wheel forms another group of drive connection again, drives 2 rotation of double-pinion planetary gear member when the sun 6 input torque of gear member, because
The internal gear for the part 1 being meshed therewith is fixed, so self energy makees public affairs around the center of internal gear by stepped gear
Turn, since the two-stage of the stepped gear in rotation has the different number of teeth or modulus, so engaged respectively with stepped gear two-stage
Just produce differential between fixed internal tooth and movable internal tooth, result just produces the rotary motion of the output shaft with internal tooth.It adjusts
The number of teeth and modulus of the whole above-mentioned gear being respectively meshed can be so that speed ratio be effectively changed.
Fig. 1 is another structure type of double star wheel reducers;His output shaft is not the output shaft member with internal tooth
3, but occupy output sun gear member 8 of the two-stage planet wheel to the rotation center direction side of star wheel frame.
It is the schematic diagram of each components in above-mentioned installation diagram shown in Fig. 1, to aid in illustrating its working principle.
Claims (3)
1. having a rotatable planetary wheel carrier in the fuselage with fixed annulus, there is several and planet on planetary wheel carrier
Wheel center is in the double pinions of radiation symmetric distribution, the level-one of the double pinions, inside be located at casing center
Sun gear is meshed, and outside is then meshed with the internal gear for being fixed on fuselage, another grade of double pinions then with a band
The output shaft of internal gear is meshed, and the internal gear three in the level-one and fuselage of such sun gear and two-stage planet wheel forms one
Group drive connection;And both another grade of twin-stage wheel and internal gear of output shaft form another group of drive connection, work as the sun
Two-stage planet wheel entirety rotation is driven when taking turns input torque, because the internal gear being meshed therewith is fixed, so only
It can be revolved by stepped gear around the center of internal gear, since the two-stage of the stepped gear in rotation has the different number of teeth or mould
Number, so the difference of speed ratio is produced in two groups of drive connections above-mentioned, in the fixation engaged respectively with stepped gear two-stage
Just produce differential between tooth and movable internal tooth, what result made the output shaft with internal tooth rotates movement.
2. the number of teeth and modulus of the above-mentioned gear being respectively meshed are adjusted, it can be to the biography taken turns to from the sun between internal tooth output shaft
Dynamic speed ratio is controlled effectively.
3. the speed reducer according to claim 1, it is characterized in that double pinions and the output surveyed in it are too
Sun wheel is meshed, and the compound motion that the rotation and revolution of double pinions are formed drives output sun gear to make output rotation.
