Abstract

The invention discloses a composite bearing structure which is used for containing a spindle. The composite bearing structure comprises a spindle sleeve, a bearing and first flow blocking pieces; the spindle sleeve is provided with a containing space; the bearing is arranged in the containing space of the spindle sleeve and provided with a spindle hole; the spindle hole is used for containing the spindle; the bearing and the spindle sleeve form a cavity; the cavity communicates with the spindle hole; and the first flow blocking pieces are arranged in the cavity and sleeved with the bearing. According to the composite bearing structure, the first flow blocking pieces are arranged in the cavity and sleeved with the bearing, so that the length of a flowing path of lubricating oil in the cavity can be effectively increased, and the lubricating oil is not prone to leaking out from a small gap between the spindle sleeve and the bearing.

Description

technical field [0001] The invention relates to a composite bearing structure, in particular to a composite bearing structure with flow blocking parts. Background technique [0002] In mechanical structures, rotating elements are often used to transmit power or change shape. In order to make the components rotate smoothly, most of the bearing structures are used to support the rotating components, and lubricating oil is injected between the bearing structure and the rotating components to reduce the friction generated when the rotating components rotate in the bearing structure. [0003] However, the friction between the rotating element and the bearing structure will be converted into heat energy during operation. Once the lubricating oil is heated, its fluidity will increase, so that the lubricating oil will easily leak out from the gap of the bearing structure, resulting in the friction between the rotating element and the bearing structure. The lubricating oil between t...
