Claims

[Scope of utility model registration request]

(1) Between a shaft member in which at least one step is formed on the outer periphery of the shaft, a housing in which two steps are formed in the inner periphery, and the shaft member and the housing. two angular contact type rolling bearings mounted in such a manner that the small-diameter side end surfaces of each other's outer rings and the small-diameter side end surfaces of each other's inner rings face each other; A bearing device comprising a pressing means for axially pressing a shaft member to fix both bearings in the axial direction with a predetermined internal clearance between the bearings, wherein the shaft member is attached to the outer periphery from the root to the tip of the shaft. Two identical stepped portions are formed in a stepped manner, and one of the two bearings connects the large-diameter end face of the inner ring of the bearing to the same stepped portion on the root side. It is installed between the shaft member and the 71 housing in such a way that the small diameter side end surface of the outer ring is brought into contact with the radial flat surface of one of the same steps of the 71 housing, The other bearing has the smaller diameter side end face of the inner ring facing the radial flat part of the same step on the shaft tip side of the shaft member with a predetermined gap, and the smaller diameter side end face of the outer ring faces the other side of the housing. The shaft member is mounted between the shaft member and the housing so as to be in contact with the radial flat part of the same step part, and the positional relationship between the shaft member, the housing, and the two bearings is as described above. No. 1 The axial distance between the two radial flat parts of the same step part of the housing is A, the width of the assembly of the bearing installed on the root side of the shaft is B, and the width of the bearing installed on the root side of the shaft member is B, and the width of the two same step parts of the shaft member is The axial distance between the two radial flat parts is 01.The amount of axial protrusion of the outer ring small diameter side end face of the bearing relative to the inner ring small diameter side end face is x1.The radius of the same stepped part on the shaft tip side of the shaft member. When the axial clearance between the opposing surfaces between the direction flat part and the inner ring small diameter side end face of the bearing on the tip end side of the shaft is defined as Y, the relationship is defined as A+B+X=C+Y, and the axial clearance Y is set equal to the amount of axial displacement of the inner ring of the bearing on the tip side of the shaft when a predetermined positive or negative internal clearance is given to the two bearings, and the pressing means The inner ring of the bearing is pressed in the axial direction from its large-diameter end face, and the small-diameter end face of the inner ring is brought into contact with the radial flat part of the same step on the shaft tip side of the shaft member. A bearing device characterized in that the two bearings are fixed in the axial direction.゛

(2) The bearing device according to claim 1, wherein the angular contact type rolling bearing is a tapered roller bearing.

(3) The fixing means includes a threaded portion formed on the outer periphery of the shaft tip of the shaft member and a nut member screwed into the threaded portion, and the fixing means is configured to secure the inner ring of the bearing mounted on the shaft tip side of the shaft member. Utility model registration claim 1 or 2, which is fixed by being pressed in the axial direction by tightening the nut member.
The bearing device according to any of paragraphs.
