Abstract
The invention provides a concentric transmission structure. An outer transmission shaft is of a hollow structure, and an inner transmission shaft is sleeved with the outer transmission shaft. The central line of the inner transmission shaft and the central line of the outer transmission shaft coincide. The inner transmission shaft and the outer transmission shaft are connected through a bearing pack. The outer transmission shaft is connected with a supporting seat through a bearing pack. The shaft ends on the two sides of the outer transmission shaft are each provided with an outer transmission shaft output end. The outer transmission shaft output ends stretch out of the two sides of the supporting seat correspondingly. The two sides of the inner transmission shaft are each provided with an inner transmission shaft output end. Each inner transmission shaft output end stretches out of the corresponding outer transmission shaft output end. The inner transmission shaft is mounted inside the outer transmission shaft. The two sides of the inner transmission shaft are each provided with a joint with an externally connecting function. The outer transmission shaft is mounted on the supporting seat through the bearing pack. The two sides of the outer transmission shaft are provided with an input joint with an externally connecting function and an output joint with an externally connecting function correspondingly. Transmission of the inner transmission shaft and transmission of the outer transmission shaft are carried out independently and do not affect each other. By means of the unique and novel transmission structure, the development test difficulties of a certain type of aircraft engines in China are overcome.
Description
Technical field:
The present invention relates to mechanical transmission fields, be specifically related to concentric drive mechanism.
Background technology:
During certain type aero-engine development test, need the special transmission requirement that a kind of double-shaft concentric exports.
Summary of the invention:
In order to solve the problems referred to above, it is contemplated that propose a kind of drive mechanism with one heart.
The technical scheme is that concentric drive mechanism, including outer power transmission shaft, outer power transmission shaft is hollow-core construction, unofficial biography
Moving axis 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 and outer power transmission shaft pass through axle
Holding 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 outfan, institute
The outer power transmission shaft outfan stated 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.
There is advantages that intermediate solid drive shaft is installed on inside outer power transmission shaft by bearing group, intermediate solid drive shaft
Both sides have the input of external linkage function, output interface, and 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, and intermediate solid drive shaft is relatively independent with outer transmission shaft driven, is independent of each other,
The present invention solves the technical barrier of China's type aero-engine development test by unique, novel drive mechanism.
Accompanying drawing illustrates:
Accompanying drawing 1 is the structural representation of the present invention.
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 invention will be further described 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, in outer power transmission shaft 2 is enclosed within
Outside power transmission 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 are by bearing group 3
Connecting, 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 all there is intermediate solid drive shaft outfan the both sides of intermediate solid drive shaft 1
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 the present invention is by unique, new
The drive mechanism of grain husk 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.
