Abstract
The utility model discloses a kind of riveting axle sleeves, including cylindrical portions and ring part；The internal diameter of cylindrical portions inner hole and the major diameter fit of axis；One face of ring part is plane, no less than three rivets have circumferentially been evenly arranged close to edge in plane, the outer diameter of ring part outer circle cooperates with the internal diameter of impeller inner hole respectively, axle sleeve ring part is inserted into impeller inner hole, due to the plasticity of material, the rivet being evenly arranged in circular planes hammers into the disk spreading after disk axle sleeve, makes to connect fastening between axle sleeve and impeller；Axle sleeve is manufactured using big material is plastically deformed.Using the plasticity of material, axle sleeve is hammered into multiple rivets, axle sleeve is connect fastening with impeller by spreading axle sleeve, will not both damage the structural strength of impeller itself, and assembly also facilitates.
Description
Technical field
The utility model relates to a kind of axle sleeve, specifically a kind of riveting axle sleeve.
Background technique
Impeller needs to be mounted on an axle by axle sleeve, since impeller is than relatively thin, not only influences impeller using screw connection
Intensity, and assembled in structure very inconvenient.
Utility model content
The purpose of this utility model be propose it is a kind of on impeller intensity influence it is small, and assemble also easily riveting axle sleeve.
The utility model adopts the following technical solution:
A kind of riveting axle sleeve, the ring part of cylindrical portions and periphery including inside；
The internal diameter of the cylindrical portions inner hole and the major diameter fit of axis；
One face of the ring part is plane, has circumferentially been evenly arranged in plane close to edge and has been no less than three
Rivet, the outer diameter of ring part outer circle and the internal diameter of impeller inner hole cooperate, and axle sleeve ring part is inserted into impeller inner hole, due to material
Plasticity, the rivet being evenly arranged in circular planes hammers into the disk edge spreading after disk axle sleeve, makes axle sleeve and impeller
Between connect fastening；
Optimization, axle sleeve can choose U.S. MPIF standard FC0205 using big material manufacture is plastically deformed.
The utility model utilizes the plasticity of material, hammers into axle sleeve with multiple rivets, spreading axle sleeve connect axle sleeve with impeller
Fastening, will not both damage the structural strength of impeller itself, and assembly also facilitates.
Detailed description of the invention:
Attached drawing 1 and Fig. 2 are the main view and split cross-sectional view of the utility model respectively；
In Fig. 1,1 is the inner hole of cylindrical portions, and 2 be the plane of ring part, and 3 be the rivet that circular planes are evenly arranged, 4
It is the outer circle of ring part；
Specific embodiment
The utility model is described further with reference to the accompanying drawings and detailed description:
In Fig. 1 and Fig. 2, a face of the internal diameter of cylindrical portions inner hole 1 and the major diameter fit of axis, ring part is plane 2,
In plane 2 close to edge be circumferentially evenly arranged no less than three rivets 3, the outer diameter of ring part outer circle 4 respectively with leaf
The internal diameter cooperation for taking turns inner hole, after axle sleeve is inserted into impeller inner hole, due to the plasticity of material, the rivet that is evenly arranged in circular planes
The disk spreading after disk axle sleeve is hammered into, makes to connect fastening between axle sleeve and impeller；
The axle sleeve of the utility model selects U.S. MPIF using big material manufacture, specific proposed materials are plastically deformed
Standard FC0205.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
