W/ 2), it has advantage simple in structure and that application is strong, for the full roller radially self-locking bearing from last roller of axially packing into provides a kind of new structure.
Description
The present invention relates to a kind of rolling bearing, particularly a kind of short columnar roller radially self-locking full type roller bearing.
Pack into the vertically assembly method of last roller of the radially self-locking full type roller bearing that existing outer ring has two ribs mainly contains two kinds, promptly one of two ribs are shaped on the breach that radial depth equals the rib height vertically in the outer ring, be called for short " complete dark breach ", the shortcoming of this method is that the irregular and roller of rib stress distribution leads when running up not good enough, easily produces similar Train wheel stays the seam place by track interface ill effect; Or the rib endoporus of one of two ribs in outer ring increased make so-called " critical diameter rib ", the weakness of this method is that roller may be from axially dropping out, the height of rib is quite low, has lost the meaning of two ribs.
Purpose of the present invention is exactly to have the radially self-locking full type roller bearing that contour pair of rib can make good last roller of axially packing into of roller running guiding for the deficiency of avoiding above-mentioned technology provides a kind of outer ring.
Pack into vertically " complete dark breach " of last roller, the reason that its weakness produces is that notch depth equates with the rib height, causes " coming to nothing " when roller turns over breach, causes roller and breach limit to collide, and roller is turned round lead bad; And the deadly defect of " critical diameter rib " is highly too low, strength deficiency; Roller is in critical self-locking state when no inner ring, the self-locking poor stability of roller.Keep away its two weak point, get its two length, just having constituted technological scheme of the present invention is: no retainer radially self-locking full type roller bearing, the outer ring has contour pair of rib, it is characterized in that being axially arranged with in a rib upper edge of two ribs outer ring can be for " the high breach in the critical end " from last roller of axially packing into, high H at the bottom of the radially bosom of this breach radially has a section to the raceway of outer ring.
The essence of " the high breach in the critical end " of the present invention is a non-complete dark breach, and it has avoided " complete dark breach " to reach the deficiency of " critical diameter rib "; It has and is skillfully constructed, simple in structure and advantage that application is strong.

Height at the bottom of the H-breach (the radially bosom of " the high breach in the critical end " is radially to the outer ring raceway distance).
The determination of main parameters of full roller radially self-locking bearing is a prior art, is published in having on " bearing ": the design of full roller radially self-locking bearing, and bearing, 1986(6): 1～5; Full roller radially self-locking design bearing computational methods, bearing, 1989(3): 15～18; Full roller is the relevant calculation of roller bearing entad, bearing, 1989(4): 5～8; The design method of full roller radially self-locking cylindrical roller bearing, bearing 1989(6): 13～16; The design of full roller radially self-locking bearing, bearing, 1990(2): 2～8.Therefore the present invention no longer discusses.
Analyze and calculate with regard to " the high breach in the critical end " of the present invention below:
From Fig. 3 analysis as can be seen, when all rollers all along raceway when arranging, the center O of roller I
3Be moved to C point and roller II, III is tangent and is in the standard radially self-locking, therefore, as long as the high H≤D in the end of " the high breach in the critical end " 4
1/ the roller I can be packed into vertically from breach 2(OC+Dw/2) time.
Can derive from Fig. 3:

Work as H=D
1/ 2-(Yc+Dw/2), the roller I is packed into vertically from breach 4 and just is in the non-threshold state of packing into of can packing into, and the H value of this moment is exactly the height of the critical end of breach 4.
(3) formula can have multiple expression-form, but its essence all is to express the end high expressed formula of breach 4.
Basic building block of the present invention is made up of two rib outer ring 1, several rollers 2 and a single block border inner ring 3, it is characterized in that being axially arranged with in a rib upper edge of two ribs outer ring 1 can be for " the high breach in the critical end " 4 from last roller of axially packing into, high H at the bottom of the radially bosom of this breach radially has one section to the raceway of outer ring 1 is as H≤D
1/ 2-(Yc+Dw/2) time, just can be from " the high breach in the critical end " 4 last roller of packing into vertically.
Outer ring, folk art term of the present invention limit, its grade limit diameter D
2Both can also can select as required by GB.
Pattern of the present invention both can be fit to not have the dust cover formula, also can be fit to the dust cover formula; The outer surface of its outer ring 1 can be sphere shape, also can make cylinder shape belt location stop flange or cylinder shape belt location stop flange or cylinder shape belt locking groove; That its inner ring 3 can be made into single block border or do not have rib; The endoporus of inner ring 3 can be made into cylindrical hole or conical bore; Outer ring of the present invention 1 end face also can be made into convex type or inner ring 3 end faces are convex type; The present invention can also not have inner ring 3 formulas.Roller 2 of the present invention can be single-column type or double-row type, and every row roller 2 numbers can from 5 to 26.
" the high breach in the critical end " 4 on the outer ring 1 can be processed after heat treatment, in order to avoid heat treatment deformation and stress concentration.
The present invention is axially arranged with in a rib upper edge of two ribs outer ring 1 can be for " the high breach in the critical end " 4 from last roller of axially packing into, it has avoided " complete dark breach " to reach the deficiency of " critical diameter rib ", for the full roller radially self-locking bearing from last roller of axially packing into provides a kind of new structure.It has be skillfully constructed, simple in structure, application is strong.Reach the advantage that assembling need not be heated.
