Patent ID: 8632250

Claim:
A hybrid lubricating module, comprising: a housing which is a hollow tube with an axial cavity inside; and an assembly including at least two elements, each element including two opposite ends, each end forming a connection portion, the at least two elements including at least one set of two adjacent elements being axially coupled together with one of the two adjacent elements abutting against another one of the two adjacent elements to allow at least one set of two abutting connection portions of the at least one set of the two adjacent elements to be closely contacted therebetween to form the assembly, and a largest circumferential outer wall surface between two connection portions of each element forming a mounting portion to allow the assembly to be fixedly encased in and fully contacted with the cavity of the housing to form the hybrid lubricating module, each element also including at least one waist portion defined between the two connection portions of each element, any circumferential outer wall surface of the at least one waist portion having smaller radial dimension than the largest circumferential outer wall surface of the mounting portion, such that at least one storage chamber of the hybrid lubricating module being cooperatively formed between a circumferential outer wall surface of the assembly and a circumferential inner wall surface of the housing to store lubricating media therein, each element further containing an axle hole axially running through the two opposite ends thereof, axle holes of the at least two elements forming an axial hole of the assembly for insertion of a spinning shaft to be supported and lubricated by the hybrid lubricating module; wherein the at least one waist portion is axially concaved from the mounting portion towards at least one of the two connection portions, at least one set of multiple notches being defined between the at least one set of the two adjacent elements of the assembly and annularly formed on at least one of the two abutting connection portions and communicated with the at least one waist portion and the axle hole, the at least one set of multiple notches forming at least one set of multiple passages of the assembly to communicate with the at least one storage chamber and the axial hole.
