Problems solved by technology

[0003] However, the two spring sheets of the aforementioned known preloaded spring sheet group are not integrated into one body. When the shaft passes through the two preloaded spring sheets, each preloaded spring sheet will produce inconsistent radial rotation or / or axial rotation. vibration, causing them to be skewed in their original positions. At the same time, the preloaded spring piece does not abut the bearing in the axial direction, and the spring force does not act on the bearing evenly, so that the preloaded pressure on the bearing is not parallel to the axial direction, and the bearing will Vibration and noise
[0004] Furthermore, it will interfere with the assembly of the buckle and the shaft, so that the buckle cannot be fastened to the shaft, causing the rotor to loosen

Embodiment Construction

[0083] see Figure 1A and Figure 1B , is a schematic diagram of a pre-compression spring 10 , which includes a body 11 , a plurality of extension elements 12 and at least one protrusion 13 as shown in the figure.

[0084] The main body 11 has an inner surface 112 defining a through hole 111 passing through the main body 11, so that the main body 11 is formed into an annular body, and an outer surface 113 is defined on the outer peripheral side of the main body 11, and a first contact surface 114 is defined on the outer peripheral side of the main body 11. Between the outer surface 113 and the inner surface 112 .

[0085] At least one engaging portion 115 and at least one engaging groove 116 are distributed on the outer surface 113 or adjacent to the outer surface 113, wherein the engaging portion 115 protrudes from the first contact surface 114, and the engaging groove 116 is provided on the outer surface 113 without The position of the engaging portion 115 is recessed towar...

Abstract

The invention discloses a preloaded spring piece, a composite structure thereof and a fan. A preloaded spring piece set supplies a preloaded force to a bearing and comprises a first body which is connected with a second body in a butting mode. The first body is provided with at least one first clamping portion, at least one first clamping groove and at least one first protruding portion. The second body is provided with at least one second clamping portion, at least one second clamping groove and at least one second protruding portion. The first clamping portion is tightly clamped with the second clamping groove, the second clamping portion is tightly clamped with the first clamping groove, and the first protruding portion correspondingly makes contact with the second protruding portion so as to enable the first body and the second body to be combined into a whole.

Description

technical field [0001] The invention relates to a pre-compressed spring sheet, in particular to a combined structure of a pre-compressed spring sheet group, and a fan with the pre-compressed spring sheet group. Background technique [0002] The known pre-compressed spring sheet group consists of two pre-compressed spring sheets stacked on the shaft rod and inserted on the shaft rod, and abutted between a bearing and a retaining ring to provide a pre-load to the bearing , to prevent bearing vibration and reduce noise. [0003] However, the two spring sheets of the aforementioned known preloaded spring sheet group are not combined into one body. When the shaft passes through the two preloaded spring sheets, each preloaded spring sheet will produce inconsistent radial rotation or / or axial rotation. Vibration causes them to be skewed in their original positions. At the same time, the preloaded spring piece does not abut the bearing in the axial direction, and the spring force d...
