Abstract
The invention belongs to properller designing techniques, are related to the attachment device of a kind of coaxial co-axial contra rotating propeller front row propeller and heel row propeller.The present invention includes paddle shaft, end face lid, casing, thrust ball bearing and fixing bearing；The paddle shaft is mounted on casing by thrust ball bearing and fixing bearing；The end face lid is mounted on casing front end, to keep the lubrication sealing of bearing and keep the preload of paddle shaft；The casing is mounted on heel row propeller paddle shell；Spline in the front row propeller paddle shaft is connected with the spline on engine driving torsional axis, drives front-seat propeller rotation；It is described front row propeller and heel row propeller it is coaxial to turn, in the course of work, the pulling force or negative pulling force that front-seat propeller generates are transmitted on heel row propeller paddle shell by paddle shaft, since heel row propeller is connected with engine paddle shaft, therefore the pulling force of front-seat propeller and negative pulling force are transferred on engine, and then are transmitted on aircraft.
Description
Technical field
The invention belongs to properller designing technique, it is related to a kind of coaxial co-axial contra rotating propeller front row propeller and heel row spiral shell
Revolve the attachment device of paddle.
Background technique
In common turbo oar engine (such as -6 engine of whirlpool paddle, T56 engine), one propeller rotation of engine driving
Turn, the pulling force/thrust generated during propeller works passes to engine by paddle shaft, and then passes to aircraft wing, drives
Aircraft flight.
It is made of in coaxial co-axial contra rotating propeller front-seat propeller and heel row propeller, front-seat propeller and heel row propeller
Direction of rotation it is opposite.It is limited by engine and propeller arrangement, front-seat propeller can only splined shaft biography provided by the engine
Revolving speed is passed, therefore the power that front-seat propeller generates can only be transmitted on engine by heel row propeller.Heel row propeller then may be used
It is directly driven in a manner of using traditional turbo oar engine by paddle shaft, and the power for transmitting propeller generation.Due to front and rear row
Propeller direction of rotation is on the contrary, therefore the support revolving speed between front-seat propeller and heel row propeller is front-seat propeller and heel row
The sum of revolution speed of propeller.Therefore, heel row spiral is transmitted in coaxial co-axial contra rotating propeller, needing to solve front-seat propeller pulling force
The problem of paddle and front and rear row propeller relative rotation.
Summary of the invention
The object of the present invention is to provide a kind of connection of coaxial co-axial contra rotating propeller front row propeller and heel row propeller dresses
It sets, to solve the problems, such as that front-seat propeller pulling force is transmitted to heel row propeller and front and rear row propeller relative rotation.
The technical scheme is that the connection of a kind of coaxial co-axial contra rotating propeller front row propeller and heel row propeller fills
It sets, including paddle shaft, end face lid, casing, thrust ball bearing and fixing bearing；The paddle shaft passes through thrust ball bearing and fixing bearing
It is mounted on casing；The end face lid is mounted on casing front end, to keep the lubrication sealing of bearing and keep the preload of paddle shaft；Institute
Casing is stated to be mounted on heel row propeller paddle shell；The spline on spline and engine driving torsional axis in the front row propeller paddle shaft
It is connected, drives front-seat propeller rotation；The front row propeller and heel row propeller are coaxial to turn, in the course of work, front-seat spiral shell
The pulling force or negative pulling force that rotation paddle generates are transmitted on heel row propeller paddle shell by paddle shaft, due to heel row propeller and engine paddle
Axis is connected, therefore the pulling force of front-seat propeller and negative pulling force are transferred on engine, and then are transmitted on aircraft.
Further, lubricating cavity is set among the paddle shaft and casing, inside is full of the lubricating grease for bearing lubrication.
The beneficial effects of the present invention are: a kind of company of coaxial co-axial contra rotating propeller front row propeller and heel row propeller of the present invention
Connection device plays the purpose of support paddle shaft by setting casing and bearing, solves rotation and the transmitting pulling force of front-seat propeller
The problem of.

Propeller paddle shaft 2, stud 3, nut 4, end face lid 5, roller bearing 6, casing 7, ball bearing 8, screw 9.
It is coaxial to engine operation is turned when, engine driving torsional axis 10 and heel row propeller paddle shaft 14 by engine driving,
Middle 10 clockwise of engine driving torsional axis rotation, heel row propeller paddle shaft 14 rotate counterclockwise.
Heel row propeller paddle shell 11 is mounted in heel row propeller paddle shaft by propeller 13 and nut 12, heel row propeller
Paddle shaft 14 drives paddle shell 11 to rotate.The pulling force and negative pulling force generated during heel row propeller works is transmitted to engine by paddle shaft
On.Casing 7 is mounted on heel row propeller paddle shaft 14 by screw 9, and the purpose of casing 7 is pacified for roller bearing 6 and ball bearing 8
Dress, while the pulling force for transmitting front-seat propeller and negative pulling force be to heel row propeller paddle shell 11, then by paddle shell be transmitted to engine with
On aircraft, flying power is provided；Ball bearing 8 is pre-tightened by end face lid 5.
Engine driving torsional axis 10 is connect by spline with front-seat propeller paddle shaft 2, and front-seat propeller paddle shell 1 rotates.It is front-seat
Propeller paddle shell 1 is mounted in front-seat propeller paddle shaft 2 by stud 3 and nut 4.It is generated during front-seat propeller works
Pulling force and negative pulling force pass through roller bearing by paddle shaft and are transmitted to casing.
