Des Weiteren betrifft die Erfindung auch eine Lageranordnung mit einem Lager und einer Mehrzahl von an ein gemeinsames Verbindungsmedium anschliessbarer Module, wobei die Module Bestandteile des erfindungsgemässen Baukastens sind.
摘要:
A bearing assembly having an inner race ring (14) that defines an inner raceway and an outer race ring that defines an outer raceway on which the plurality of rolling elements (22) roll. The bearing raceways are machined using surface finishing operations to create preferred surface profiles and textures for improving lubrication performance. The profile of the raceway is initially created using a first grinding process to form a rough surface profile including a rough central band (34) and rough recessed side bands (38). A second grinding process is used to smooth the central band. This raceway surface profile increases lubrication performance.

The present invention provides a bearing assembly (100) comprising a rolling element bearing having a first row of rolling elements (111) arranged in a first bearing cavity between a first inner (125) and a first outer raceway (107) of the bearing, and having a second row of rolling elements (112) arranged in a second bearing cavity between a second inner (126) and a second outer raceway (108) of the bearing. The assembly further comprises an annular grease cartridge (130) arranged between the first and second rows of rolling elements. According to the invention, the annular grease cartridge is at least partly formed from a honeycomb structure having axially extending passageways filled with a grease lubricant, wherein at least some of passageways are open towards the first and second bearing cavities.

A bearing includes an outer ring (14) having an inner surface (26), an inner ring (18) at least partially positioned within the outer ring (14) and having an outer surface (22) in facing relationship with the inner surface (26), a groove (30) defined in either the inner surface (26) or the outer surface (22), and a porous material (38) positioned in the groove (30) in which lubricant is absorbed. The porous material (38) is configured to secrete the absorbed lubricant in response to being compressed.

The rolling bearing comprises an inner ring 1, an outer ring 2, at least one row of rolling elements 3 positioned between raceways provided on the rings, and at least an annular housing 5 inside which at least one of the rings is arranged, the said ring is at least in two portions 2a, 2b. The housing 5 comprises at least two distinct parts 20, 21 for retaining the portions 2a, 2b of the said ring and fixing means 26; 44; 50 for fixing the said parts together. Each of the two portions of said ring delimits with the housing a closed space 31 a, 31b inside which a lubricant is located. Passage means for the lubricant comprising axial holes 33a, 33b at least partly facing one another are made in the thickness of a radial portion 12a, 12b of each of the two portions 2a, 2b of said ring and put the two closed spaces into communication.
摘要:
This invention provides a heat reversible gel-like lubricating composition having such properties that, in a service bulk temperature region, the composition is in a semi-solid gel form as with grease, but on the other hand, in a local high-temperature region such as a sliding contact site, the composition is homogeneously melted, is free from a drawback of grease, i.e., the precipitation of foreign materials, exhibit excellent low frictional characteristics unrealizable by grease, and exhibits significant energy saving properties. The heat reversible gel-like lubricating composition comprises a mineral oil and/or synthetic liquid lubricating base oil and a bisamide and/or a monoamide and has heat reversible gel properties. Preferably, the heat reversible gel-like lubricating composition contains a triamide and further contains, based on 100 parts by weight of the liquid lubricating base oil, 0.01 to 500 parts by weight in total of a bisamide and a monoamide and 0.05 to 10 parts by weight of a friction regulator.
