Abstract
The utility model proposes concentric drive mechanism.Outer power transmission shaft is hollow-core construction, outer power transmission shaft is enclosed within outside intermediate solid drive shaft, intermediate solid drive shaft overlaps with the centrage of outer power transmission shaft, intermediate solid drive shaft is connected by bearing group with outer power transmission shaft, outer power transmission shaft passes through bearing group connecting support seat, and the spindle nose of outer power transmission shaft both sides all has outer power transmission shaft outfan, described outer power transmission shaft outfan to reach outside support seat both sides, the both sides of intermediate solid drive shaft all have intermediate solid drive shaft outfan, each intermediate solid drive shaft outfan to reach outside corresponding outer power transmission shaft outfan.Intermediate solid drive shaft is installed on inside outer power transmission shaft, intermediate solid drive shaft both sides have the interface of external linkage function, outer power transmission shaft is installed on support seat by bearing group, outer power transmission shaft both sides have the input of external linkage function, output interface, intermediate solid drive shaft is relatively independent with outer transmission shaft driven, being independent of each other, this utility model solves the technical barrier of China's type aero-engine development test by unique, novel drive mechanism.
Description
Technical field:
This utility model relates to mechanical transmission fields, is specifically related to concentric drive mechanism.
Background technology:
During certain type aero-engine development test, the special transmission needing a kind of double-shaft concentric to export is wanted
Ask.
Utility model content:
In order to solve the problems referred to above, this utility model is directed to a kind of drive mechanism with one heart.
The technical solution of the utility model is: drive mechanism with one heart, and including outer power transmission shaft, outer power transmission shaft is hollow-core construction,
Outer power transmission shaft is enclosed within outside intermediate solid drive shaft, and intermediate solid drive shaft overlaps with the centrage of outer power transmission shaft, and intermediate solid drive shaft leads to outer power transmission shaft
Crossing bearing group to connect, outer power transmission shaft passes through bearing group connecting support seat, and the spindle nose of outer power transmission shaft both sides all has outer power transmission shaft to export
End, described outer power transmission shaft outfan reaches outside support seat both sides, and all there is intermediate solid drive shaft outfan the both sides of intermediate solid drive shaft,
Each intermediate solid drive shaft outfan reaches outside corresponding outer power transmission shaft outfan.
This utility model has the advantages that intermediate solid drive shaft is installed on inside outer power transmission shaft by bearing group, interior biography
Moving axis both sides have the input of external linkage function, output interface, and outer power transmission shaft is installed on support seat by bearing group, unofficial biography
Moving axis both sides have the input of external linkage function, output interface, and intermediate solid drive shaft is relatively independent with outer transmission shaft driven, the most not shadow
Ringing, the technology that this utility model solves China's type aero-engine development test by unique, novel drive mechanism is difficult
Topic.
Accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present utility model.
1-intermediate solid drive shaft in figure, the outer power transmission shaft of 2-, 3-bearing group, 4-supports seat, 5-intermediate solid drive shaft outfan, the outer transmission of 6-
Axle outfan.
Detailed description of the invention:
The utility model is described in further detail below in conjunction with the accompanying drawings:
As shown in Figure 1, concentric drive mechanism, including outer power transmission shaft 2, outer power transmission shaft 2 is hollow-core construction, and outer power transmission shaft 2 overlaps
Outside intermediate solid drive shaft 1, intermediate solid drive shaft 1 overlaps with the centrage of outer power transmission shaft 2, and intermediate solid drive shaft 1 and outer power transmission shaft 2 pass through bearing
Group 3 connection, outer power transmission shaft 2 is by bearing group 3 connecting support seat 4, and the spindle nose of outer power transmission shaft 2 both sides all has outer power transmission shaft outfan
6, described outer power transmission shaft outfan 6 reaches outside support seat 4 both sides, and the both sides of intermediate solid drive shaft 1 all have intermediate solid drive shaft to export
End 5, each intermediate solid drive shaft outfan 5 reaches outside corresponding outer power transmission shaft outfan 6.
It is internal that intermediate solid drive shaft 1 is installed on outer power transmission shaft 2 by bearing group 3, and intermediate solid drive shaft 1 both sides have external linkage function
Input, output interface, outer power transmission shaft 2 is installed on support seat 4 by bearing group 3, and outer power transmission shaft 2 both sides have externally connection
The input of function, output interface, intermediate solid drive shaft is relatively independent with outer transmission shaft driven, is independent of each other, and this utility model is by solely
Special, novel drive mechanism solves the technical barrier of China's type aero-engine development test.
Intermediate solid drive shaft 1, outer power transmission shaft 2 can be combined by many shaft parts, described bearing group 3 can be sliding bearing or
Rolling bearing, intermediate solid drive shaft outfan 5 and outer power transmission shaft outfan 6 can be flange, spline or other forms.
