Embodiment Construction

[0027] The number, length, width, and Radian, raised height and rounded corners r1 and r2.

[0028] Specific as figure 1 and figure 2 , there are four convex ribs 2 on the radial surface of the rotating shaft 1, the convex ribs 2 are integrated with the rotating shaft 1, and the convex ribs 2 are evenly distributed on the rotating shaft. One end of the convex rib 2 is arc-shaped, which is the smooth end 3 with ribs, and the other end is stepped, which is the stepped end 4 with ribs. In this way, when the rotating shaft is pressed into the through hole, there is a sliding transition section between the rotating shaft and the through hole. The rotating shaft has an auxiliary guiding (positive) function during the sliding process, and is not easy to be damaged and pressed into the peripheral surface of the through hole.

[0029] The fillet r1 in this embodiment is greater than r2, such as image 3 shown. Figure 4 The height of the protrusion at the end of the middle step ...

Abstract

The invention provides a light high-strength tendon-accompanied spindle which is made of nylon material. The radial surface of the spindle is provided with more than one convex tendon which is integrated with the spindle, and the convex tendons are evenly distributed on the spindle; the preferable scheme is characterized in that one end of each convex tendon is in circular arc shape, the other end is in step shape, and the fillet r1 of one end of the circular arc is more than r2. The invention has the advantages of simple structure and easy processing, and is suitable for small and tiny mechanical and electrical products. Compared with the mechanical and structural connecting and positioning mode, the spindle has simple processing technology and simple self structure and can position without adding auxiliary holes on parts fixed with the spindle.

Description

technical field [0001] The invention relates to a rotating shaft, in particular to a rotating shaft suitable for fixing and connecting rotor components in small and micro electromechanical products when they are assembled. Background technique [0002] In electromechanical products, the fixed connection methods of mechanical parts can be divided into process type and matching type. [0003] (1) The process type is made by adding through holes or threaded holes on the shaft or mechanical parts, and then tightening the connection with screws during assembly. This connection method involves many processes, tool types and equipment types in the production of parts, and the process of process preparation is complicated. [0004] (2) Cooperating type The through hole of the rotating shaft and the part connected with the rotating shaft is processed to match and have a certain tapered shape, and the purpose of fixed connection is achieved through the coupling of the tapered surface...
