Abstract
The aviation single-web wheel with the balance sheet comprises the balance sheet, countersunk head screws and a wheel hub, wherein the balance sheet is made of high-strength stainless steel, and a threaded hole in the wheel hub is positioned at the outer side of a fixed wheel rim of a light point of the wheel hub; at present, the static balance of the aviation single-web wheel is mostly matched by adding a cylinder or cuboid metal at the position of a hub web, the existing aviation single-web wheel balancing piece is mostly made of structural steel, and the surface of the existing aviation single-web wheel is plated with cadmium and passivated in a surface treatment mode, so that the corrosion resistance of metal parts is poor, and the metal parts are mostly designed at the position of the hub web where the bearing load of the wheel is large; according to the aviation single-web wheel with the balancing piece, the corrosion resistance of the balancing piece is improved, the bearing capacity of the web of the hub of the aviation single-web wheel is improved, and the dynamic fatigue performance of the hub of the aviation single-web wheel is prolonged.
Description
Technical Field
The utility model relates to the technical field of machine wheel design, in particular to an aviation single-web machine wheel with a balance piece.
Background
At present, the static balance of the aviation single-web wheel is mostly matched by adding a cylinder or cuboid metal at the position of a hub web plate, the existing aviation single-web wheel balancing piece is mostly made of structural steel, and the surface of the existing aviation single-web wheel balancing piece is subjected to a cadmium-plated passivation surface treatment mode, so that the corrosion resistance of metal parts is poor, and the static strength performance and the dynamic fatigue performance of the wheel are reduced due to the fact that the metal parts are mostly designed at the position of the hub web plate with larger bearing load of the wheel; the aviation single-web wheel with the balancing piece is designed for meeting the requirements of the existing aviation single-web wheel on severe environment resistance and no influence on static strength performance and dynamic fatigue performance of the wheel.
Disclosure of Invention
In order to solve the problems in the background art, the utility model provides an aviation single-web wheel with a balancing piece.
The utility model discloses the following technical scheme: the utility model provides an aviation single web wheel of area balancing piece, includes balancing piece, countersunk head screw and wheel hub, there is countersunk head screw mounting hole on the balancing piece, there is the screw hole on the wheel hub, the balancing piece passes through countersunk head screw to be installed on wheel hub, balancing piece material is high strength stainless steel, the screw hole on the wheel hub is located the fixed rim outside of wheel hub light point position.
Further, the countersunk head screw (2) is a countersunk head screw with a straight groove of 90 degrees.
Furthermore, punching points are arranged on two sides of the straight slot of the screw head of the countersunk head screw, and the positions of the countersunk head screw and the balance piece are fixed in a locking manner by adopting the punching points.
The beneficial effects are that: compared with the prior art, the aviation single-web wheel with the balancing piece can solve the problems that the balancing piece of the aviation single-web wheel is not resistant to environmental corrosion and affects the static strength performance and the dynamic fatigue performance of the wheel, improve the corrosion resistance of the balancing piece, improve the bearing capacity of the web of the hub of the aviation single-web wheel and prolong the dynamic fatigue performance of the hub of the aviation single-web wheel.

FIG. 2 is a schematic illustration of an aircraft single web wheel with balancing piece of the present utility model;
fig. 3 is a schematic view in the direction a in fig. 2.
In the figure: 1-balancing piece, 2-countersunk head screw, 3-hub, B-punching point position, 31-hub web position and 4-balancing piece in the prior art.
Detailed Description
As shown in FIG. 1, the static balance of the prior art aviation single-web wheel is mostly matched by adding a cylinder or cuboid metal at the position of a hub web, the prior aviation single-web wheel balance piece is mostly made of structural steel, and the surface of the prior aviation single-web wheel balance piece is passivated by plating cadmium.
As shown in figures 2 and 3, the aviation single-web wheel with the balance piece comprises the balance piece, countersunk head screws and a wheel hub, wherein countersunk head screw mounting holes are formed in the balance piece, threaded holes are formed in the wheel hub, the balance piece is arranged on the wheel hub through the countersunk head screws, the balance piece is made of high-strength stainless steel and has high corrosion resistance, the threaded holes in the wheel hub are positioned on the outer side of a fixed wheel rim of a light point position of the wheel hub, web positions of important bearing parts of the wheel hub are avoided, bearing capacity of a web of the aviation single-web wheel can be improved, and dynamic fatigue performance of the wheel hub of the aviation single-web wheel is prolonged.
The countersunk head screw (2) is a countersunk head screw with a straight slot of 90 degrees, punching points are arranged on two sides of the straight slot of the screw head of the countersunk head screw, the countersunk head screw is loose in a punching point loose-proof mode, the position relation between the countersunk head screw and the balance piece is fixed, and firmness and reliability of the countersunk head screw and the balance piece can be guaranteed.
When the balance sheet is installed, the wheel is subjected to a static balance test, the light weight and the key point of the wheel hub are determined, the screw holes are drilled on the outer side of the fixed wheel rim at the light point position, the web plate position of the important bearing part of the wheel hub is avoided, the screw holes are matched with the countersunk head screws, the balance sheet is installed on the wheel hub, after the countersunk head screws are screwed up, the countersunk head screws are prevented from loosening in a punching point locking mode, and the installation mode is simple, quick, firm and reliable.
The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
