Abstract
The utility model discloses a double-shaft synchronous transmission device, which includes an upper shaft and a lower shaft, wherein a gear A is fixed on the upper shaft; a gear D is fixed on the lower shaft; the double-shaft synchronous transmission device further includes a planetary gear set A, consisting of a gear B and a gear C; the gear B is a planet gear, and the gear C is a sun gear; the gear A is meshed with the gear B; the gear C is meshed with the gear D; the gear B and the gear A are connected through a connecting rod A to form a planetary gear set B; and in the planetary gear set B, the gear B is a sun gear, and the gear A is a planet gear. As a lower shaft driving system is only used for providing dynamic force for the upper and the lower shafts, compared with the traditional differential case adopting the transmission manner through being equipped with an upper shaft universal coupling and a lower shaft universal coupling, the double-shaft synchronous transmission device has more compact structure and big transmission moment, and can keep the entire gear train in a normal meshing transmission state when the upper shaft ascends or descends, and the synchronous transmission accuracy of the upper and the lower shafts are higher.
Description
Technical field
The utility model relates to a kind of synchronizer, particularly a kind of two rotating shafts synchronizer of rotation synchronously that drives.
Background technique
Slitter and feeder include axle and lower shaft; Should guarantee the free lifting of axle, also will guarantee the synchronous rotation of axle and lower shaft, at present; Slitter and feeder go up axle and lower shaft be by differential box mix, the kind of drive transmission of lower shaft Hooks coupling universal coupling; Structure is not compact, and last lower shaft Synchronous Transmission precision is low, slitting, pushing precision and second-rate.
Summary of the invention
The problem that the utility model will solve is: provide a kind of twin shaft synchronization accuracy high twin shaft synchronous transmission device.
For addressing the above problem, the utility model comprises axle and lower shaft, and described going up on the axle is fixed with gear A; Fixed gear D on the described lower shaft also includes a planetary gear set A, and planetary gear set A comprises gear B and gear C; Gear B is a planet wheel, and gear C is a sun gear, and gear A and gear B are meshed; Gear C and gear D are meshed, and gear B and gear A connect into planetary gear set B through connecting rod A, and planetary gear set B middle gear B is that sun gear, gear A are planet wheel.
In order to make two planetary gear set reliable motion; The gear shaft B of said connecting rod A and last axle and gear B all is rotationally connected; Described planetary gear set A also includes connecting rod B and support, and the gear shaft C of gear C rotates and is arranged on the support, and connecting rod B and gear shaft B and gear shaft C all are rotationally connected.
In order to make two planetary gear set reliable motion; Described connecting rod A comprises two parallel baffle plate A; Gear A and gear B are clipped between the two baffle plate A, and last axle and gear shaft B all are rotationally connected with two baffle plate A, and connecting rod B comprises two parallel baffle plate B; Gear B and gear C are clipped between the two baffle plate B, and gear shaft B and gear shaft C all are rotationally connected with two baffle plate B.
The beneficial effect of the utility model: the utility model realizes that the power of upper and lower axle is only provided by the lower shaft drive system, than traditional differential box mix, the kind of drive of lower shaft Hooks coupling universal coupling, more compact structure; Driving torque is big; When last axle goes up and down, remain the equal normal engaged transmission of train of gearings, make that upward lower shaft Synchronous Transmission precision is higher; Be suitable on the slitter of sheet material processing and the feeder and lower shaft, using, make that slitting, pushing precision and quality are higher.
