Bearing assembly

A bearing assembly, comprising:

• a housing having a through hole extending along an axial direction of the housing;
• a first bearing and a second bearing coaxially set within the through hole, wherein the second bearing is located at one end of the through hole, the first bearing is located at an other end of the through hole, and each of the first bearing and the second bearing comprise an inner ring and an outer ring;
• a first shaft sleeve set between the first bearing and the second bearing along the axial direction;
• and
• an end cap located at the other end of the through hole, which is able to be connected with the housing and adapted to rotate relatively to the housing, wherein the first bearing is located between the end cap and the first shaft sleeve along the axial direction,
• wherein the housing is configured with a first protrusion radially and inwardly extending from an inside wall of the housing;
• and the end cap is configured with a second protrusion radially and outwardly extending from an outside wall of the end cap, wherein the housing and the end cap are able to be connected together via the first protrusion and the second protrusion,
• further comprising a second shaft sleeve, wherein one end of the second shaft sleeve stands against the inner ring of the first bearing, and the end cap is located at an other end of the second shaft sleeve away from the first bearing, wherein the end cap comprises an annular cap body extending along a radial direction;
• a first folding part extending from an inner periphery of the cap body along the axial direction;
• and a second folding part extending from an outer periphery of the cap body along the axial direction, wherein the first folding part is held within the second shaft sleeve, and the second folding part is connected with the second protrusion.

A bearing assembly, comprising:

• a housing having a through hole extending along an axial direction of the housing;
• a first bearing and a second bearing coaxially set within the through hole, wherein the second bearing is located at one end of the through hole, the first bearing is located at an other end of the through hole, and each of the first bearing and the second bearing comprise an inner ring and an outer ring;
• a first shaft sleeve set between the first bearing and the second bearing along the axial direction;
• and
• an end cap located at the other end of the through hole, which is able to be connected with the housing and adapted to rotate relatively to the housing, wherein the first bearing is located between the end cap and the first shaft sleeve along the axial direction,
• further comprising an elastic element set in a space defined by the first shaft sleeve and the housing, wherein one end of the elastic element stands against the outer ring of the first bearing along the axial direction
• wherein the housing comprises a first portion;
• a second portion for accommodating the first bearing, the elastic element and the end cap;
• and a third portion for accommodating the second bearing, wherein the second portion and the third portion are respectively located at two ends of the first portion along the axial direction, the second portion has an inner diameter larger than that of the first portion to form a first shoulder at junction of the first portion and the second portion, and an other end of the elastic element stands against the first shoulder along the axial direction.
