Embodiment Construction
[0033] Exemplary embodiments of the present application are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present application, but are not intended to exhaust all possible ways of the present application, nor are they used to limit the scope of the present application.
[0034] In the following specific embodiments, the conductive oil guide assembly according to the present application is located between the first member and the second member that can rotate relative to each other (such as the outer ring and inner ring of the bearing), and the conductive oil guide assembly is ring-shaped as a whole . In this application, unless otherwise specified, "axial", "radial" and "circumferential" refer to the axial, radial and circumferential directions of the conductive oil guide assembly respectively. The axial, radial and circumferential direct...

The invention provides an electric conduction and oil conduction assembly, a bearing and an electric bridge driving system. The electric conduction and oil conduction assembly has conductive performance. And under the condition that the electric conduction and oil conduction assembly is applied to the bearing, the electric conduction and oil conduction assembly is always in contact with the outer ring and the inner ring of the bearing. Even if the bearing is applied to an electrified occasion, the electric connection between the outer ring and the inner ring can be realized through the electric conduction and oil conduction assembly, so that charges are released in time, and adverse effects on the lubricating performance and the service life of the bearing due to accumulated charges of the bearing are avoided. An oil guide hole is further formed in the electric conduction and oil conduction assembly. Under the condition that the electric conduction and oil conduction assembly is applied to the bearing, lubricating media on the two sides of the bearing can flow through the bearing through the oil guide hole, and therefore parts around the bearing can be lubricated. Furthermore, the bearing comprising the electric conduction and oil conduction assembly and the electric bridge driving system comprising the bearing have the same functions.
Description
technical field [0001] The present application relates to the field of bearings, and more specifically relates to a conductive oil-conducting component, a bearing including the conductive and oil-conducting component, and an electric bridge drive system including the bearing. Background technique [0002] figure 1 A schematic cross-sectional view showing a partial structure of a bearing (such as a deep groove ball bearing) used in a live application. Such as figure 1 As shown, the bearing includes a seal assembly 10 , an outer ring 20 and an inner ring 30 . Seal assembly 10 is located between outer ring 20 and inner ring 30 . The outer ring 20 is located radially outside the inner ring 30 , and the outer ring 20 and the inner ring 30 can rotate relative to each other. A plurality of rolling elements (not shown) held by a cage (not shown) are housed and mounted between the outer ring 20 and the inner ring 30 . Further, the sealing assembly 10 is fixed to the outer ring 2...
