Description
Technical field
This utility model relates to a kind of planetary reduction gear, particularly to one double outputting planetary speed reducer in the same direction.
Background technology
Planetary reduction gear is also called planetary reducer, servo deceleration device, in decelerator family, planetary reduction gear is little with its volume, and transmission efficiency is high, and reduction range is wide, the plurality of advantages such as precision is high, and it being widely used in the drive systems such as servomotor, motor, direct current generator, its effect is exactly under the premise ensureing precision drive, is mainly used to reduce rotating speed and increases moment of torsion and reduce the rotary inertia ratio of load/motor. Planetary reduction gear general in the market is mostly unidirectional single output planetary decelerator, and the speed ratio of output is more single, commercially promotes on a large scale so limiting planetary reduction gear.
Summary of the invention
The purpose of this utility model is in that to solve the deficiencies in the prior art, this utility model provide a kind of compact conformation, lightweight, medium and bigger power can be transmitted, take up room the double outputting planetary speed reducer in the same direction of different speed ratio little, exportable in use.
This utility model solves its technical problem the technical scheme is that one double outputting planetary speed reducer in the same direction, including input flange, output flange, fixing duplex ring gear it is provided with between described input flange, output flange, it is provided with one-level band centre wheel planet carrier in fixing duplex ring gear, one-level band centre wheel planet carrier is provided with primary planet wheel shaft, primary planet wheel shaft is provided with the primary planet wheel that the internal tooth with fixing duplex ring gear is meshed, and described one-level takes turns, with primary planet, the input centre wheel being meshed with being additionally provided with in centre wheel planet carrier; Two grades of band output shaft planet carriers it are additionally provided with in described fixing duplex ring gear, two grades of band output shaft planet carriers are provided with secondary planet wheel shaft, secondary planet wheel shaft is provided with the secondary planet wheel being meshed with the one-level centre wheel with centre wheel planet carrier front end, secondary planet wheel is also meshed with the internal tooth of fixing duplex ring gear, being arranged with output ring gear outside described two grades of band output shaft planet carriers, the internal tooth of output ring gear is meshed with secondary planet wheel.
This utility model is a kind of planetary reduction gear of two kinds of different speed ratios of output on same, it is made up of NGW type and two kinds of Gear Planet Transmission types of NGWN type respectively, wherein NGWN type can obtain very big speed reducing ratio (can reach 1000:1 according to the structure speed ratio of decelerator higher even), and compact integral structure, volume is little, lightweight, medium and bigger power can be transmitted, take up room in use little, in assembling process by some parts be optimized group join the performance that can make complete machine and transmission efficiency bring up to 95% or more than, owing to there is dual output in the same direction and exporting the feature of different speed ratio, under certain conditions it is contemplated that a tractor serves several purposes when making client in type selecting or use.
