Abstract
Abstract The invention relates to a device for fastening an axle with rolling bearings in a cylindrical tubing comprising two annular sleeves having inward extensions for locking up the outer races of the rolling bearings with fastening members for relatively fixing the sleeves in place and with an outward shoulder at the end remote from the fastening members. The invention provides a device of the kind set forth, in which the sleeves are made from elastic material and the sleeves each have an inner groove at the end having the shoulder for fitting the outer races of the bearings and at the other ends hook-like fastening members fitting around one another, while the outer sleeve has longitudinal slots at said end.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
186 words
A device for fastening an axle with rolling bearings in a cylindrical tubing comprising: two annular sleeves having inward extensions for locking up outer races of the rolling bearings and having hook-like fastening members for relatively fixing the sleeves in place relative to the cylindrical tubing; an outward shoulder positioned at the ends of said annular sleeves remote from the fastening members; said sleeves being constructed from elastically resilient material and having an inner groove at the ends provided with said shoulders for fitting the outer races of the bearings and the other ends being provided with said hook-like fastening members; said annular sleeves being fitted one around the other and the outer sleeve being provided with longitudinal slots at said end containing said hook-like fastening member; wherein the hook-like fastening members are formed by an outer shoulder on the inner sleeve and an inner shoulder on the outer sleeve, said inner and outer shoulders being directed towards said other ends and at least one of the sleeves includes a conical surface for forming a leading rim at the insertion of one sleeve into the other.
Claim 2
Independent Claim
186 words
A device for fastening an axle with rolling bearings in a cylindrical tubing comprising: two annular sleeves having inward extensions for locking up outer races of the rolling bearings and having hook-like fastening members for relatively fixing the sleeves in place relative to the cylindrical tubing; an outward shoulder positioned at the ends of said annular sleeves remote from the fastening members; said sleeves being constructed from elastically resilient material and having an inner groove at the ends provided with said shoulders for fitting the outer races of the bearings and the other ends being provided with said hook-like fastening members; said annular sleeves being fitted one around the other and the outer sleeve being provided with longitudinal slots at said end containing said hook-like fastening member; wherein the hook-like fastening members are formed by an outer shoulder on the inner sleeve and an inner shoulder on the outer sleeve, said inner and outer shoulders being directed towards said other ends and at least one of the sleeves includes a conical surface for forming a leading rim at the insertion of one sleeve into the other.
Claim 3
Dependent Claim
24 words
A device as claimed in claim 1, wherein the ends having the inner grooves for the rolling bearings of said sleeves include longitudinal slots.
Claim 4
Dependent Claim
41 words
A device as claimed in claim 1 or 2, wherein the side remote from the fastening members of the sleeves include a flaring end, the largest diameter of which is at least equal to the largest diameter of the inner groove.
Claim 5
Dependent Claim
15 words
A device as claimed in claim 3, wherein the device is made of synthetic resin.
Claim 6
Dependent Claim
16 words
A device as claimed in claim 4, wherein the device is made of polyamide or polyacetal.
Claim 7
Dependent Claim
268 words
A sleeve assembly for fastening rolling bearings in operative relationship relative to an axle disposed within a cylindrical tubing comprising: an inner sleeve having a predetermined length; an outer shoulder positioned at one end of said inner sleeve for engagement with the cylindrical tubing; a fastening member positioned at the other end of said inner sleeve; a groove provided at the outer shoulder end of said inner sleeve for receiving an outer race of said rolling bearing and for operatively positioning an inner race of said rolling bearing in engagement with said axle; an outer sleeve having a predetermined length; an outer shoulder positioned at one end of said outer sleeve for engagement with the cylindrical tubing; a fastening member positioned at the other end of said outer sleeve; a groove provided at the outer shoulder end of said outer sleeve for receiving an outer race of said rolling bearing and for operatively positioning an inner race of said rolling bearing in engagement with said axle; said inner and outer sleeves being fitted one within the other and said outer sleeve including at least one longitudinal slot for permitting said outer sleeve to be biased outwardly as said inner sleeve is initially inserted therein and being resilient to snap back to the original configuration of said outer sleeve after said fastening member of said inner sleeve lockingly engages with said fastening member of said outer sleeve for operatively positioning said inner and outer sleeves within said cylindrical tubing with said rolling bearings being in contact with said axle and said outer shoulder of said inner and outer sleeves.
Claim 8
Dependent Claim
268 words
A sleeve assembly for fastening rolling bearings in operative relationship relative to an axle disposed within a cylindrical tubing comprising: an inner sleeve having a predetermined length; an outer shoulder positioned at one end of said inner sleeve for engagement with the cylindrical tubing; a fastening member positioned at the other end of said inner sleeve; a groove provided at the outer shoulder end of said inner sleeve for receiving an outer race of said rolling bearing and for operatively positioning an inner race of said rolling bearing in engagement with said axle; an outer sleeve having a predetermined length; an outer shoulder positioned at one end of said outer sleeve for engagement with the cylindrical tubing; a fastening member positioned at the other end of said outer sleeve; a groove provided at the outer shoulder end of said outer sleeve for receiving an outer race of said rolling bearing and for operatively positioning an inner race of said rolling bearing in engagement with said axle; said inner and outer sleeves being fitted one within the other and said outer sleeve including at least one longitudinal slot for permitting said outer sleeve to be biased outwardly as said inner sleeve is initially inserted therein and being resilient to snap back to the original configuration of said outer sleeve after said fastening member of said inner sleeve lockingly engages with said fastening member of said outer sleeve for operatively positioning said inner and outer sleeves within said cylindrical tubing with said rolling bearings being in contact with said axle and said outer shoulder of said inner and outer sleeves.
Claim 9
Dependent Claim
38 words
