Abstract
Official abstract text for this publication.
A bearing assembly including a chamber provided with a rolling bearing supporting a rotary shaft with respect to a fixed housing. The rolling bearing has a first ring and a second ring in relative rotation one each other, at least one row of rolling elements being arranged between the rings. The chamber having Ethanol in liquid and/or gaseous state. The rings are coated with diamond-like carbon (DLC) material.
First claim
Opening claim text (preview).
What is claimed is: 1. A bearing assembly comprising: a chamber provided with a rolling bearing that supports a rotary shaft with respect to a fixed housing, the rolling bearing comprising: a first ring having radially extending first ring axial ends, a second ring in relative rotation to the first ring, the second ring having radially extending second ring axial ends, at least one row of rolling elements being arranged between the rings, wherein the rolling elements are circumferentially maintained by a cage, the chamber comprising Ethanol wherein a first portion of the Ethanol being in a liquid state and a second portion of the Ethanol being in a gaseous state, the chamber being partially defined by the first and second rings such that the Ethanol is in contact with: (1) the radially extending first ring axial ends; (2) the radially extending second ring axial ends; (3) and the cage, wherein the rings are coated with diamond-like carbon (DLC) material. 2. The bearing assembly according to the claim 1 , wherein the rings are made of steel of 100Cr6 grade. 3. The bearing assembly according to claim 1 , wherein the rolling elements are made of ceramic material. 4. The bearing assembly according to claim 1 , wherein the rolling elements are made of stainless steel. 5. The bearing assembly according to claim 1 , wherein the Ethanol acts as a lubricant for the rolling elements. 6. The bearing assembly according to the claim 5 , wherein the cage is made of Polyetheretherketone (PEEK). 7. A bearing assembly comprising: a chamber provided with a rolling bearing that supports a rotary shaft with respect to a fixed housing, the rolling bearing comprising: a first ring having radially extending first ring axial ends, a second ring in relative rotation to the first ring, the second ring having radially extending second ring axial ends, at least one row of rolling elements being arranged between the rings, the chamber comprising Ethanol wherein a first portion of the Ethanol being in a liquid state and a second portion of the Ethanol being in a gaseous state, the Ethanol being in contact with: (1) the radially extending first ring axial ends; and (2) the radially extending second ring axial ends, wherein the Ethanol acts as a lubricant for the rolling elements, wherein the rings are coated with diamond-like carbon (DLC) material. 8. The bearing assembly according to the claim 7 , wherein the rings are made of steel of 100Cr6 grade. 9. The bearing assembly according to claim 7 , wherein the rolling elements are made of ceramic material. 10. The bearing assembly according to the claim 9 , wherein the rolling elements are circumferentially maintained by a cage, the cage is made of Polyetheretherketone (PEEK). 11. The bearing assembly according to claim 7 , wherein the rolling elements are made of stainless steel. 12. A bearing assembly comprising: a chamber provided with a rolling bearing that supports a rotary shaft with respect to a fixed housing, the rolling bearing comprising: a first ring having radially extending first ring axial ends, a second ring in relative rotation to the first ring, the second ring having radially extending second ring axial ends, at least one row of rolling elements being arranged between the rings, the chamber comprising Ethanol in a liquid state, the Ethanol being in contact with: (1) the radially extending first ring axial ends; and (2) the radially extending second ring axial ends, wherein the Ethanol acts as a lubricant for the rolling elements, wherein the rings are coated with diamond-like carbon (DLC) material. 13. The bearing assembly according to the claim 12 , wherein the rings are made of steel of 100Cr6 grade. 14. The bearing assembly according to claim 12 , wherein the rolling elements are made of ceramic material. 15. The bearing assembly according to claim 14 , wherein the rolling elements are circumferentially maintained by a cage, the cage is made of Polyetheretherketone (PEEK). 16. The bearing assembly according to claim 12 , wherein the rolling elements are made of stainless steel.
