Description
Technical field
The utility model relates to mechanical transmissioning technology field, is specifically related to a kind of single planet carrier large transmission ratio planetary variable speed drive.
Background technique
Gear Planet Transmission because thering is compact structure, bearing capacity is large, stable drive is efficient, feature easy to install, that the life-span is long is widely used in every profession and trade.Along with the national energy-saving consumption reduction proposition of target and the continuous application of new technology, miniaturization, high-mechanic to mechanical transmission mechanism are had higher requirement.Domestic market planetary driving device is owing to being subject to structural limitations, and it is very large that single-stage planetary velocity ratio can not do.The occasion that needs big speed ratio and need gear for those, often needs the combining form of multistage planet transmission and other shifting mechanism, and transmission structures complexity, volume are increased, and has lost the inherent characteristics of planetary driving device.
Summary of the invention
The purpose of this utility model is: a kind of single planet carrier large transmission ratio planetary variable speed drive is provided, this transmission device adopts single planet carrier, double planet wheel and double sun gear are set, each toothrow wheel of double sun gear engages respectively and realizes different velocity ratios from the corresponding gear of double planet wheel, realizes big speed ratio and planet speed-change transmission.
Technical solution of the present utility model is: ring gear is installed in casing, planet carrier is installed in casing and case lid by planet carrier bearing, double planet wheel is installed in planet carrier by planet wheel bearing and planet wheel shaft, multiple double planet wheels are uniform along planet carrier gyration center, double sun gear is installed in case lid and planet carrier by sun wheel shaft and sun wheel shaft bearing, connecting sleeve is connected with double sun gear, gear shift slide block is arranged in the circular groove of connecting sleeve, sun wheel shaft is splined shaft, double sun gear in sun wheel shaft under the promotion of gear shift slide block along sliding axially, double sun gear wherein every toothrow wheel engages respectively with the corresponding gear of double planet wheel, one of double planet wheel toothrow wheel engages with ring gear, bearing (ball) cover is installed in the outer end of sun wheel shaft bearing and planet carrier bearing.
Wherein, described double sun gear and double planet wheel are set to three rows and the above many toothrows wheel construction of three rows as required.
When work, using sun wheel shaft as input end, each toothrow wheel of double sun gear engages with the corresponding toothrow wheel of double planet wheel respectively, and one of double planet wheel toothrow wheel engages with ring gear, exports by planet carrier; Otherwise, using planet carrier as input end, export from sun wheel shaft.
According to above solution, this transmission device reaches following effect: 1. the double sun gear in sun wheel shaft under the promotion of gear shift slide block along sliding axially, double sun gear wherein every toothrow wheel engages respectively with the corresponding gear of double planet wheel, one of double planet wheel toothrow wheel engages with ring gear, realizes variable gear ratio; 2. sun gear and planet wheel adopt double or arrange structure more, and each toothrow wheel is configured to the different numbers of teeth, obtain the velocity ratio larger than single-stage planetary transmission; 3. double sun gear is positioned at planet carrier inside as change gear, has utilized former the having living space in planet carrier, makes compact structure; 3. sun wheel shaft and planet carrier all can be used as input end or output terminal, and mode is flexible.
