Abstract
A preload disk spring assembly structure for applying a preload to a bearing includes a first and a second main body correspondingly connected to each other face to face. The first main body is provided with at least one first retainer, at least one first notch, and at least one first protruded portion. Similarly, the second main body is provided with at least one second retainer, at least one second notch, and at least one second protruded portion. When the first and the second main body are aligned with each other such that the first retainer is tightly engaged with the second notch, the first notch is tightly engaged with the second retainer and the first protruded portion correspondingly contacts with the second protruded portion, the first and the second main body are brought to assemble together and form an integral body.
