1、DEUTSCHE NORM Julv 1999 Rolling bearings with spherical outside surface and extended inner ring Part 1 : Insert bearings DIN 626-1 - ICs 21.1 00.20 Supersedes February 1979 edition Wlzlager - Rillenkugellager mit kugelfrmiger Auenringmantelflche und verbreitertem Innenring - Teil 1 : Spannlager In k
2、eeping with current practice in standards published by the International Organization for Standardization (ISO), a comma has been used throughout as the decimal marker. Foreword This standard has been prepared by the Arbeitsausschuss Walzlager (Rolling Bearings Standards Com- mitt ee) . It conforms
3、in substance to IS0 9628 : 1992, except that a) insert bearings with concentric locking collar around the inner ring and the specifications relating to inner ring eccentric extension and radial internal clearance have not been included; b) the range of nominal sizes covered in tables 1 to 3 has been
4、 extended to include 1 O0 mm; c) tables 1 to 3 have been supplemented by the addition of columns for dimensionB, mass and symbol. Amendments This standard differs from the February 1979 edition in that it has been editorially revised and type YAL insert bearings have been included. Previous edition
5、DIN 626-1 : 1979-02. All dimensions are in mm. 1 Scope This standard specifies the dimensions, mass and bore diametertolerances for three types of rolling bearing with a spherical outside surface and an extended inner ring with a locking device. Type YEL and YEN bearings have an eccentric locking co
6、llar for fixing the inner ring to the shaft (see figures 1 and 2), and type YAL bearings are fixed to the shaft by means of set screws in the inner ring (see figure 3). The outer ring of all three types of bearing has a spherical outside surface so that the bearing can be mounted in a housing with a
7、 matching spherical seat, thus providing correct alignment. Using these bearings with housings complying with DIN 626-2 reduces the need for expensive machining processes, and allows the use of standard shafts. 2 Normative references This standard incorporates, by dated or undated reference, provisi
8、ons from other publications. These normative references are cited at the appropriate places in the text, and the titles of the publications are listed below. For dated references, subsequent amendments to or revisions of any of these publications apply to this standard only when incorporated in it b

Design details not given here remain unspecified. The bore diameters and outside diameters given in tab
14、les 1 to 3 correspond to diameter series 2 as given in DIN 616, except for nominal sizes, d, of 12 mm, 15 mm, and 65 mm. The inner ring widths specified here are greater than those specified in DIN 61 6. For type YEL and YEN bearings, where the locking device extends axially beyond the inner ring, t
15、he width over the locking device, called the overall width (B,), is specified. For type YAL bearings, where the locking device is not axially extending beyond the inner ring, dimension B is the overall inner ring width. In accordance with IS0 9628, the three overall width series given are designated
16、 wide (type YEL), intermediate (type YAL) and narrow (type YEN). 4.1 Types 4.1.1 Type YEL insert bearing with eccentric locking collar (wide overall width) locking IW I collar B, Figure 1: Bearing with eccentric locking collar, inner ring extended on both sides - Wide overall width (see table 1) Des
