  • Patent number: 10753396
    Abstract: A Hybrid rolling bearing includes an inner raceway and an outer raceway and a plurality of rolling elements arranged therebetween. The outer raceway and the inner raceway are made from bearing steel, having a first surface RMS roughness Rq1. The rolling elements are made from a ceramic material and have second surface RMS roughnesses Rq2,i. At least one of the rolling elements has an increased surface RMS roughness Rq2,N, which is significantly higher than the RMS roughnesses Rq2,i, of the remaining rolling elements. The hybrid rolling bearing can be installed within a refrigerant compressor.

  • Publication number: 20200166252
    Abstract: Disclosed is a cooling system comprising a refrigerant cycle for cycling refrigerant from at least a compressor unit for com-pressing gaseous refrigerant to a condenser unit for condensing gaseous refrigerant to liquid refrigerant, from the condenser unit to an evaporator unit for evaporating the liquid refrigerant to gaseous refrigerant, and from the evaporating unit back to the compressor unit, and a lubrication cycle having at least one lubricating refrigerant supply line for providing refrigerant as lubricant to a bearing assembly, wherein the at least one lubricating refrigerant supply line branches off from the refrigerant cycle at the condenser unit for providing refrigerant to the bearing assembly, and re-unites with the refrigerant cycle at the evaporator unit, for feeding back refrigerant from the bearing assembly to the refrigerant cycle.

  • Patent number: 10527094
    Abstract: A Hybrid ball bearing including an outer raceway, an inner raceway, and a plurality of balls arranged between the inner raceway and the outer raceway. The outer raceway and the inner raceway are made from bearing steel and have a first surface RMS roughness Rq1. At least one ball of the plurality of balls is made from a ceramic material and has a second surface RMS roughness Rq2. In a mint condition, the roughness of the raceways Rq1 is 2 to 5 times higher than the roughness Rq2 of the at least one ball, as well as a refrigerant compressor comprising such a hybrid ball bearing.

  • Publication number: 20160160857
    Abstract: A lubricant supply system includes first and second tanks, each including an internal volume that is divided into a first portion and a second portion. The first portion of the internal volume of the first tank and the first portion of the internal volume of the second tank are configured to alternate supplying a liquid refrigerant to a machine. A pump is in fluid communication with the second portion of the internal volume of the first tank and the second portion of the internal volume of the second tank. The pump is configured to vary a pressure of a gas in the second portion of the internal volume of the first tank and the second portion of the internal volume of the second tank.

  • Patent number: 8360650
    Abstract: A method for lubricating a rolling element bearing by an ultra low viscosity volatile fluid comprises injecting a liquefied fluid flow into the bearing, lubricating rolling contacts between the rings and the rolling elements of the bearing by the liquefied fluid, providing a flow restriction for the liquefied fluid so as to maintain at least part of the fluid at a pressure which is above the evaporation pressure which is defined by evaporation of the fluid at the temperature or temperatures which prevail(s) in the bearing.

  • Patent number: 8231277
    Abstract: A sliding bearing, such as a journal bearing, includes at least two bearing elements, the bearing surfaces of which are slidably supported with respect to each other. At least one of the surfaces is provided with a first type of cavity which may comprise a lubricating substance, the first type of cavity being defined by a specific range of geometric properties. At least one surface is provided with at least a second type of cavity which may comprise a lubricating surface, the second type of cavity being defined by geometric properties which are different from the geometric properties of the first type of cavity.
