Background technique
Low module plane table thermoconductivity meter refers to that module is less than the plane table thermoconductivity meter of 1mm, and low module plane table thermoconductivity meter application area widely.
In recent years, some high-precision technical fields are as more and more higher in the usage requirement to low module plane table thermoconductivity meter such as Aeronautics and Astronautics, precision optical machinery, not only require that low module plane table thermoconductivity meter adopts the Multi-stage transmission of more than two-stage or two-stage to improve its velocity ratio, also require that low module plane table thermoconductivity meter realizes high transmission efficiency and large bearing capacity as far as possible on the basis of improving velocity ratio.
In prior art, low module plane table thermoconductivity meter when adopting the multilevel transmission structure of more than two-stage or two-stage, the major parts such as the sun gear used and planet carrier, the same with common planetary gear retarder, be all designed to conventional structure and independently part.Its major defect is: must increase the load balancing mechanism such as monodentate coupling or bidentate coupling between two-stage Gear Planet Transmission, and the increase of the load balancing mechanism such as monodentate coupling or bidentate coupling, the transmission efficiency of plane table thermoconductivity meter and bearing capacity must be caused to reduce.
Model utility content
The purpose of this utility model is: provide the low module plane table thermoconductivity meter that a kind of compact structure, velocity ratio are large, have higher transmission efficiency and larger bearing capacity, to overcome the deficiencies in the prior art.
A kind of low module plane table thermoconductivity meter of the present utility model, comprise input shaft, ring gear, planet carrier sun gear, the first row star-wheel, the second planet wheel and output shaft, described planet carrier sun gear is the one-piece parts of tiled configuration, its left end is provided with the first row carrier, right-hand member is provided with the first gear, the first row star-wheel be arranged in the first row carrier engages with the second gear on input shaft and the first internal gear on ring gear respectively, the primary planet transmission of composition Gear Planet Transmission; Described output shaft is provided with the second planet carrier, and the second planet wheel be arranged on the second planet carrier engages with the secondary annulus on the first gear and ring gear respectively, the secondary planet transmission of composition Gear Planet Transmission.
The first concave surface that the first hemisphere boss that central position, aforesaid input shaft right side is provided with and central position, the first row carrier left side are provided with coordinates, and realizes the axially locating of primary planet transmission.
The second concave surface that the second hemisphere boss that aforesaid first central position, gear right side is provided with and the second central position, planet carrier left side are provided with coordinates, and realizes the axially locating of secondary planet transmission.
Owing to have employed technique scheme, the utility model has the advantage of: low module plane table thermoconductivity meter is designed to two-stage planet transmission by the utility model, the input shaft of retarder and the as a whole part of the second design of gears of primary planet transmission, the first row carrier of primary planet transmission and the as a whole part of the first design of gears of secondary planet transmission, second planet carrier of secondary planet transmission and output shaft are designed to an one-piece parts, improve the structural strength of epicyclic transmission mechanism major part.In addition, in the utility model, I and II Gear Planet Transmission all adopts spherical boss to coordinate with concave surface and realizes axially locating, do not need between two-stage Gear Planet Transmission to arrange the load balancing mechanism such as monodentate coupling or bidentate coupling, therefore, while planetary gearing speed reducer has compared with big speed ratio, there is again higher transmission efficiency and larger bearing capacity.
