Abstract
The utility model provides a micro planet gear speed reducer whose gear shaft 1 is meshed with planet gears 9, and the three planet gear 9 are distributed on the concentric circumference of the gear shaft 1 and are installed on a planetary frame 4, being engaged with a stationary gear 7 and an output annular gear 10. An intermediate ring 6 forms a crosshead block type coupling together with the annular gear 7 and an end closure 5, and the micro modulus 'm' is equal to zero. The utility model has the advantages of simple and compact structure, small size, light weight, large transmission ratio, high transmission efficiency, easy fabrication, etc.
Description
Miniature plane table thermoconductivity meter of the present utility model belongs to precision optical machinery and gear reducer field.
(m＜1mm) is a harmonic gear reducer to existing little modulus plane table thermoconductivity meter.Harmonic speed reducer is made up of wave-generator, flexible gear and three basic building blocks of rigid gear usually.Although that it has is simple in structure, in light weight, volume is little, velocity ratio is big, kinematic accuracy is high and characteristics such as transmission efficiency height.Its working principle is under the effect of wave-generator, forces flexbile gear to produce resiliently deformable, and is meshing with each other and transmitting movement or power with firm wheel.But this retarder owing to the resiliently deformable of flexbile gear makes its gear teeth produce relative slippage, thereby makes the wheel between cog of two-wheeled produce friction and wear in its working procedure.In addition, the processing of flexbile gear is difficulty, complicated, and general factory still can not make.
The purpose of this utility model be to provide a kind of rigid gear, compact structure, novelty, volume is little, in light weight, velocity ratio is big, transmission efficiency is high, reliable operation, long service life, and miniature plane table thermoconductivity meter easy to manufacture, easy for installation.
Technical solution of the present utility model: its structure as shown in the figure.It is made up of gear shaft (also claiming sun gear) 1, planetary pinion 9, planet carrier 4, fixed annulus 7, output inner gear 10, housing 8, central ring 6, end cap 5 and sealing cover 2,12 etc., and the gear shaft 1 that is positioned at the planetary reducer center is meshed with planetary pinion 9.And three planetary pinions 9 are placed on the concentric circumferences with gear shaft 1, its angle of circumference be 120 ° uniform, planetary pinion 9 is installed on the planet carrier 4.Planetary pinion 9 is interior engagement with fixed annulus 7, and simultaneously, planetary pinion 9 is meshed with the output inner gear 10 of output movement or power again.Central ring 6 matches with fixed annulus 7 and end cap 5, and forms the cross slider type coupling, but makes internal gear 7 radial floatings, little modulus m=0.1-1mm.
Accompanying drawing is a structural representation of the present utility model, below in conjunction with its transmission principle of description of drawings: when motor (not drawing on the figure) gear shaft 1 is rotated, gear shaft 1 is meshing with each other with the planetary pinion 9 that is installed on the planet carrier 4, but since internal gear 7 by central ring 6 and end cap 5 link be fixed motionless, just force planetary pinion 9 to do planetary motion, be that it both revolved round the sun around the main shaft of sun gear 1, do rotation around the axle on the planet carrier 4 again.And this planetary pinion 9 not only meshes with sun gear 1, also is meshed with internal gear 7 and output inner gear 10 simultaneously; Therefore, planet wheel 9 passes motion to internal gear 10 again, thereby can reach the purpose of gearing down.This shows that transmission principle of this retarder and common 3K type Gear Planet Transmission are basic identical, different it be to have the 3K type Gear Planet Transmission of monodentate circle planet wheel, be new-type 3K type Gear Planet Transmission.Facts have proved cause in the planetary reducer between each planet wheel the equally distributed method of load be have diversified.This planet retarder system adopts the cross slider type coupling, and the mode of all carrying that fixed annulus 7 is floated realizes that the load-balancing device of equal support method is made up of internal gear 7, central ring 6 and end cap 5.Its concrete structure is that a groove is arranged in the left side of internal gear, and the rectangle tenon on central ring right side matches with groove, and its left side groove in addition, and the rectangle tenon on it and right side is orthogonal.The rectangle tenon on end cap 5 right sides matches with the groove of central ring.When the load distribution between its planet wheel is inhomogeneous, will impel internal gear 7 to produce radial displacement by means of this load-balancing device, thus the purpose that realization is all carried.In addition, can also adopt the mode of all carrying that planet wheel 8 is floated, be about to planet wheel 8 and be installed on the spheric roller bearing with self-aligning performance, allow planet wheel 8 to float.Simultaneously, also the planet carrier 4 of installing and support planet wheel 8 can not fixed in its radial position, and allowed this planet carrier 4 to produce radial displacements, can realize the purpose of all carrying yet.In addition, between input shaft and sun gear 1, connect a gear coupling, sun gear 1 is produced float, thereby also can realize the purpose of all carrying with crowned teeth.
The Specifeca tion speeification of this miniature plane table thermoconductivity meter is:
Reduction speed ratio scope i=44-300
Modulus m=0.1-1.0mm
Transmitting movement or small-power p≤5.5KW
Transmission efficiency n=0.80-0.90
The utility model can be widely used in Aero-Space, cannon weapons, petrochemical industry, industry light industry textile industry, precision optical machinery, instrument and apparatus, medical apparatus, robot and industry mechanical arm, and industrial department such as senior electronic toys; Be specially adapted to the driving mechanism in the various servo-control systems.In a word, the utility model has extremely wide application prospect in dual-use mechanical industry.
