能够发电的轴承配件和能够发电的轴承
Abstract:
一种能够发电的轴承配件，其包括轴承部件（10,20,30）和设置到轴承部件（10,20,30）的压电发电装置，压电发电装置包括：压电层（14,34），其设置于轴承部件（10,20,30），用于通过承受包括轴承部件（10,20,30）的轴承（100）运行时轴承部件（10,20,30）的受力变化而产生电荷；第一电极层（13,33）和第二电极层（15,35），第一电极层（13,33）和第二电极层（15,35）分别设置于压电层（14,34）的两相反侧，用于收集压电层（14,34）产生的电荷而引出电流；以及电路板（37），其与第一电极层（13,33）和第二电极层（15,35）连接，用于对第一电极层（13,33）和第二电极层（15,35）引出的电流进行整流。
Abstract(English):

Provided is a bearing assembly capable of generating electricity, wherein, the bearing assembly comprises bearing members (10, 20, 30) and a piezoelectric power generator provided at the bearing members (10, 20, 30), and the piezoelectric power generator comprises: a piezoelectric layer (14, 34) provided on the bearing members (10, 20, 30) for generating a charge by bearing the force change of the bearing members (10, 20, 30) when the bearing (100) including the bearing members (10, 20, 30) is operated; a first electrode layer (13, 33) and a second layer (15, 35), the first electrode layer (13, 33) and the second electrode layer (15, 35) are respectively provided on opposite sides of the piezoelectric layer (14, 34) for collecting the charge generated by the piezoelectric layer (14, 34) to extract current; and a circuit board (37) connected to the first electrode layer (13, 33) and the second electrode layer (15, 35) for rectifying the current extracted by the first electrode layer (13, 33) and the second electrode layer (15, 35).
