Abstract
The invention discloses a high-temperature-resisting knuckle bearing for an actuator and belongs to the technical field of structural design. The knuckle bearing is composed of a rod end shaft sleeve and a shaft core. The shaft core is formed by a mesh-shaped alloy framework and ceramic powder through a high-temperature sintering process. The whole knuckle bearing is formed in a process channel of the shaft core embedding rod end shaft sleeve. The mesh-shaped alloy framework is formed by welding high-temperature alloy wires of different diameters or formed through 3D printing, the ceramic powder is hafnium carbide or zirconium carbide or tantalum carbide, the ceramic powder and the mesh-shaped alloy framework are evenly and densely combined, and the whole shaft core is formed. According to the high-temperature-resisting knuckle bearing for the actuator, the stress strength of the knuckle bearing in work can be guaranteed while thermal transmission in the working state is prevented, and the service life of the knuckle bearing can be prolonged.
Description
Technical field
The present invention relates to a kind of oscillating bearing, be specifically related to the oscillating bearing of a kind of electromotor actuator, belong to structure
Design field.
Background technology
Conventional actuator oscillating bearing is all to be made up of rustless steel or other alloys, at the high temperature ring worked long hours
Conduction of heat requirement can not be met under border, shaft core and through the bearing pin in shaft core hole, and between shaft core and rod end axle sleeve often
The phenomenon of blocking under warming occurred.For aero-engine, owing to its flight speed is the highest, temperature of incoming flow is low, thermic load shape
State is little, and the actuator oscillating bearing of conventional structure disclosure satisfy that use requirement；Punching engine for conventional comes
Saying owing to the working time is short, be the most all single use, the most all need not be too much connect from actuator oscillating bearing is tied
Heat insulation impact is considered on structure.And for a new generation's high-altitude long-time reusable electromotor of high speed, heat insulation problem
It is particularly important, in addition to needing to consider the conventional peripheral heat insulation mode being coated with, this for actuator oscillating bearing
Contact connect on also as far as possible consideration thermal protection measure, to reach the further heat insulation purpose of system.
Summary of the invention
In view of this, the invention provides a kind of high temperature resistant oscillating bearing of actuator, the heat when stoping duty
Can guarantee that while transmission when oscillating bearing works by force intensity, and the service life of oscillating bearing can be improved.
A kind of high temperature resistant oscillating bearing of actuator, this oscillating bearing is made up of rod end axle sleeve and shaft core, described shaft core by
Netted alloy skeleton and ceramic powders are made by high-sintering process, and shaft core embeds interior formation of technique conduit of rod end axle sleeve and closes
Bearings is overall.
Further, the space lattice of described netted alloy skeleton is polyhedron, netted alloy skeleton space lattice big
Little and sew with long stitches bar thickness regard design structural strength situation depending on.
Further, the space lattice of described netted alloy skeleton is tetrahedron or hexahedron, above two network
Possesses more preferable mechanical property.
Further, described netted alloy skeleton is by using the high temperature alloy silk welding fabrication of different-diameter or passing through 3D
Printing shaping.
Further, described ceramic powders is hafnium carbide, zirconium carbide or ramet, and ceramic powders enters with netted alloy skeleton
The combination that row is uniform and fine and close, forms the entirety of shaft core.
Beneficial effect:
1, the shaft core of the present invention uses netted alloy skeleton+ceramic structure, can effectively stop by transmitting at axis hole
The heat come over, it is ensured that the rod end axle sleeve being directly connected to actuator main body is unlikely to have substantial amounts of heat to be passed on, it is ensured that
Actuator main body can be under normal working temperature state；
2, the shaft core of the present invention uses netted alloy skeleton+ceramic structure, both ensure that stress when oscillating bearing works
Intensity, can carry out again alleviating of construction weight to a certain extent；
3, the ceramic surface of shaft core upper shaft hole of the present invention and the bearing pin surface through axis hole form work pairing face, it is to avoid
High temperature adhesion that the work pairing that common metal and metal are formed is worn and the damage that rubs for a long time, can be substantially improved joint
The service life of bearing.
Accompanying drawing explanation
Fig. 1 is the two-dimensional structure schematic diagram of the present invention；
Fig. 2 is the three dimensional structure schematic diagram of the present invention.
Wherein, 1-rod end axle sleeve, 2-shaft core, 3-netted alloy skeleton, 4-pottery.
Detailed description of the invention
Develop simultaneously embodiment below in conjunction with the accompanying drawings, describes the present invention.
As shown in figure 1 and 2, the invention provides a kind of high temperature resistant oscillating bearing of actuator, this oscillating bearing is by bar
End axle sleeve 1 and shaft core 2 form, and described shaft core is made up by high-sintering process of netted alloy skeleton 3 and ceramic powders, shaft core
Oscillating bearing is formed overall in the technique conduit of the circular arc bottom surface embedding rod end axle sleeve 1.
Netted alloy skeleton 3 is by using the high temperature alloy silk welding fabrication of different-diameter or by 3D printing shaping, net
The space lattice of shape alloy skeleton 3 uses tetrahedron or hexahedron；Ceramic powders is hafnium carbide HfC, zirconium carbide ZrC or ramet
TaC, ceramic powders and netted alloy skeleton carry out uniform and fine and close combination, ceramic powders differentiation during high temperature sintering
It is attached to be formed on netted alloy skeleton 3 entirety of shaft core for pottery 4.
As shown in accompanying drawing 1 right side cross-sectional view, the thickness H1 of shaft core 2 is more than the thickness H2 of rod end axle sleeve 1 mounting portion, purpose
Be in order to make oscillating bearing can in the range of certain angle beat and be unlikely to recurring structure interfere.
After actuator main body axle head loads onto oscillating bearing, can effectively suppress the transmission of heat, significantly reduce axis hole
The rising of temperature when the actuator main body caused due to conduction of heat at R1 works long hours, coordinates the heat insulation of actuator main body periphery
Layer cladding carries out associating thermal protection, it is ensured that actuator can long-time normal work in high temperature environments.
In sum, these are only presently preferred embodiments of the present invention, be not intended to limit protection scope of the present invention.
All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included in the present invention's
Within protection domain.
