Securing device for a bearing ring in a housing
View Patent ↗The invention relates to a securing device for a bearing ring in a housing. At least one spring element engages in an annular groove of the housing and at least one angled collar supports the bearing ring in an axial manner. The spring element is hook-shaped and forms an angle that extends in a radial manner towards the outside and at least partially back in the axial direction. At least one push element is formed on the securing device, which is actively connected to the spring element in such a manner that the spring element is prestressed in an axial manner, by actuating the push element.
1. A fastening device, comprising:
a cylindrical basic body;
at least one spring element having at least one angled shoulder, the shoulder being angled in hook form from the basic body radially outward and at least partially back in an axial direction; and
at least one push element which is integrally formed on the fastening device and which is operatively connected to the at least one spring element in such a way that, by the at least one push element being actuated, the at least one spring element can be prestressed and braced axially,
wherein the at least one spring element is formed from at least one spring collar integrally in one piece on the basic body, the spring collar being overturned to form a first bend radius such that the spring collar projects at least partially beyond the basic body axially, and the at least one push element is formed from a push collar integrally formed in one piece on the basic body, the push collar being overturned to form a second bend radius, such that the push collar projects at least partially beyond the basic body axially, and
wherein the spring collar of the at least one spring element projects radially further than the push collar of the at least one push element.
2. The fastening device of claim 1 , wherein the at least one push element is angled in hook form from the basic body radially outward and at least partially back into the axial direction, and during actuation of the at least one push element, the push element being capable of being loaded axially in an end region on an end face of a region angled axially back.
3. The fastening device of claim 2 , wherein the at least one push element and the at least one spring element are operatively connected to one another.
4. The fastening device of claim 3 , wherein in an event of axial load on the end region of the region angled axially back of the at least one push element, the region of the at least one spring element which is angled back at least partially into the axial direction can be spread radially away from the basic body.
5. The fastening device of claim 1 , wherein the push collar of the at least one push element projects axially beyond the basic body by an amount of a predetermineable projecting length.
6. The fastening device of claim 1 , wherein the spring collar of the at least one spring element and the push collar of the at least one push element are connected to one another in one piece at least partially in a region of a turnover to above a first and a second bend radius.
7. The fastening device of claim 1 , wherein the spring collar of the at least one spring element and the push collar of the at least one push element are separated from one another at least partially, in a part in which the spring collar and the push collar project axially beyond the basic body, by an axial slot on a circumference of the fastening device.
8. The fastening device of claim 1 , wherein the push collar has a V-shaped design in the axial direction and the fastening device is made from sheet metal.
9. The fastening device of claim 8 , wherein the fastening device is a securing snap ring.
10. The fastening device of claim 1 , wherein the at least one spring element and the at least one push element is a plurality of spring elements and push elements which are circumferentially adjacent to one another and separated by axial slots, the spring elements having in each case two adjacent push elements and a number of the spring elements and push elements being selected as a function of an diameter of the fastening device.
11. The fastening device of claim 1 , wherein the fastening device has smaller material thickness in a region of rounded transitions than in remaining regions.
