Abstract
The utility model discloses a differential speed reducer which relates to a differential speed reducing device and is characterized in that: a gear on an input shaft in a reducer body is meshed with that of a planet differential device, one input shaft and the same planet differential device are added behind the planet differential device, the two planet differential devices are meshed with each other through the gears thereof, and the other gears are respectively meshed with those of the added input shaft. The differential speed reducer adopts the combination of two-input and two-output, thus occupying small area after being provided with two working machines, being capable of meeting the working requirement of working environment for small working space and reducing the purchase expense and cost.
Description
Technical field
The utility model relates to the differential retarder.
Background technique
Current operation area generally all is that a differential retarder drives a working machine job, if when working simultaneously because of two working machines of need of work, must dispose two differential retarders so and drive two working machine work, its floor space is big, purchase commodity increases, and cost increases.If working space is limited in scope, do not hold two differential retarders and two working machines, can't be worked in this operation area.
Summary of the invention
The purpose of this utility model is to provide a differential retarder, and it is the device that an a kind of differential mechanism drives two working machines synchronously.
The technical solution of the utility model is as follows:
The utility model is by body, input shaft, the planetary differential device is formed, input shaft and planetary differential device are in body, gear engagement on gear on the input shaft and the axle, the gear engagement of gear shaft and planetary differential device, output shaft on the planetary differential device stretches out the outside of body, an input shaft and a planetary differential device identical with the protoplanet differential motion are set up in the back of its planetary differential device, output shaft on the planetary differential device stretches out the outside of body, gear on two planetary differential devices is meshing with each other, the gear on two output shafts respectively with input shaft on gear engagement.
The utility model advantage is as follows:
Because the utility model is the structure of double input, dual output, therefore, a playscript with stage directions model utility can drive two working machine work, its floor space is little, can not only satisfy the work requirements of the little working environment of working space scope, and reduce acquisition expenses, reduce cost.
