Abstract
The invention discloses a rotor laminate, which comprises a main body with a rotating shaft hole, wherein an annular groove concentric with the rotating shaft hole is punched on one side of the main body; meanwhile, a convex ledge corresponding to the annular groove is formed on the other side of the main body. A rotor can be assembled by adjusting the position of the adjacent laminates and then clamping and pressing the convex ledge into the annular groove through a simple press. Processing and connection are convenient; a process is simple and convenient; and the two end faces of the rotor manufactured are flat and smooth.
Description
Technical field
The present invention relates to rotor, be specifically related to constitute the lamination of rotor.
Technical background
Existing rotor majority is formed by connecting by some laminations, connected mode has the variety of ways such as rivet that adopt riveted joint of thimble roof pressure or employing to run through, its deficiency is to adopt thimble roof pressure riveted joint back one end face to have the top trace of protrusion, cause the out-of-flatness phenomenon, the control of riveted joint condition is had relatively high expectations, adopt the mode of the rivet that runs through then to cause complex structure, assembly increases, process complications.
Summary of the invention
Technical problem to be solved by this invention just provides a kind of rotor pack, processes easy to connectly, and technology is easy, and the two ends of rotor face of producing is smooth seamless.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: a kind of rotor pack, comprise the body that is provided with the rotating shaft perforation, it is characterized in that: described body one side upper punch is pressed with an annular groove concentric with rotating shaft perforation, forms a protruding eaves corresponding with annular groove simultaneously on the body another side.
Improved, described rotating shaft perforation hoop is provided with some latches, is convenient to engage with rotating shaft, does not need processing screens structure in rotating shaft, simplifies the fit structure of rotating shaft and lamination.
Further, described latch along body shaft to being formed slopely a circular cone structure.Be convenient to rotating shaft and insert, make rotating shaft and latch form occlusion structure simultaneously.
Preferably, the height of the described frustum of a cone is 0.1～1mm.
The present invention is pressed with an annular groove concentric with rotating shaft perforation in body one side upper punch, on the body another side, form a protruding eaves corresponding simultaneously with annular groove, after when the assembling rotor, only adjacent lamination need being adjusted the position so protruding eaves and annular groove are got final product by easy press card pressure, process easy to connect, technology is easy, and the two ends of rotor face of producing is smooth seamless.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of rotor pack of the present invention;
Fig. 2 is an A-A view among Fig. 1.
Embodiment
As depicted in figs. 1 and 2, be a kind of rotor pack of the present invention, comprise the body 1 that is provided with the rotating shaft perforation, described body one side upper punch is pressed with an annular groove 2 concentric with rotating shaft perforation, on the body another side, form a protruding eaves 3 corresponding simultaneously with annular groove, described rotating shaft perforation hoop is provided with some latches 4, and to being formed slopely a circular cone structure, the height of the described frustum of a cone is 0.1～1mm to described latch along body shaft.
Claims (4)
1. rotor pack comprises the body that is provided with the rotating shaft perforation, it is characterized in that: described body one side upper punch be pressed with one with the concentric annular groove of rotating shaft perforation, the formation one protruding eaves corresponding on the body another side simultaneously with annular groove.
