Description
Technical field
The present invention relates to the rolling bearing with rolling bearing retainer, the rolling bearing has rolling element and the axis of rolling
Carrier ring, wherein rolling element insert the retainer that an at least row is separated from each other along ring circumferential direction around the rotation axis of axial orientation
In pocket hole, wherein rolling bearing retainer has edge as axial firm portion, and wherein edge shape is ordinatedly locked in rolling
In the ring circumferential groove of component.
Background technology
A kind of rolling bearing retainer is shown in 39 17 759 A1 of DE, the axial guarantor with inner ring or on axis
The radial edges of gripping member, wherein retainer are locked in annular groove.Rolling bearing retainer connects in which can not lose whereby with inner ring
It connects.It slots being laterally guided radical to rolling bearing retainer so that retainer can be widened when on axis or inner ring.
The rolling bearing retainer being made of plastics is bulk article, and the bulk article jointly exists when being taken out from injection mold
It collects and transports in container.There are the risks that rolling bearing retainer is stuck herein.
10 2,012 208 807 A1 of DE show that a kind of axis of rolling designed for idle pulley supporting, double composition is accepted insurance
Frame is held, the rolling bearing retainer includes catch edge in one side.The rolling bearing retainer being made of plastics is when mounted
It is pulled in axis or inner ring, wherein before being caught at the edge in axis or inner ring annular groove, which radially widens.
In order to accurately be manufactured within the required tolerance for the rolling bearing retainer being made of plastics, the height at edge is opposite with it
In the consuming that the interference needs of shaft diameter or annular diameters improve.
DE 10 136 372 show it is a kind of have by plastics form it is two retainers, for idle pulley supporting it is double
Supporting arrangement.Corresponding retainer has clamping flange in avris, and the clamping flange is medially joined between the row
In the circumferential groove of the inside of transmission gear (preferably idle pulley).Compared with manufacturing through hole, surrounding for the inside in gear is manufactured
Slot is to expend.
The content of the invention
The purpose that the present invention is based on is：Realize the rolling bearing retainer of function optimization, the rolling bearing retainer
It realizes simple installation and the rolling bearing retainer can manufacture at low cost.
The purpose is realized by a kind of rolling bearing.It is also described herein is advantageously improved form.
According to the present invention it is proposed that a kind of rolling bearing being made of plastics at least one flexible connector is kept
Frame, the flexible connector include the connection chip lock piece formed by the notch of length limited.Connect chip lock piece
The elastic shrinkage of rolling bearing retainer or elasticity broadening when at least one connection sheet realizes installation.
Due to designing scheme in the structure, advantageously there is the desired larger elasticity of rolling bearing retainer, thus
Before being caught at edge in the affiliated circumferential groove of the rolling member of rolling bearing, the rolling bearing retainer can not be obstructed
It widens or shrinks with hindering.Since larger elasticity advantageously provides：Improve the stop part or edge of rolling bearing retainer.Via
The radial direction that the bigger between edge and slot advantageously occurs in the higher edge of also referred to as catch edge overlaps, i.e. the mistake of bigger
It is full of, the coincidence advantageously improves axial direction of the rolling bearing retainer on the component of the surrounding structure of rolling bearing and consolidates.
Meanwhile according to the present invention, connection chip lock piece that is forming incision tract simplifies the peace of rolling bearing retainer
Dress, because compared with the rolling bearing retainer of no flexible connector, narrow size is not required in the rolling bearing retainer
It keeps.Whereby, when installing rolling bearing retainer, both the danger of running body raceway is rolled there is no damage or there is no damages
The danger of rolling bearing retainer, it is described dangerous for example by raceway or rolling bearing retainer the scraped finish institute for generating cutting
Cause.Due to forming the notch narrowly guide, length limited for connecting chip lock piece of flexible connector, there is no as follows
It is dangerous：Be made after rolling bearing retainer taken out from injection mold when rolling bearing retainer chaining or cluster each other
Ground card is in a reservoir.
The connection chip lock piece formed according to the present invention is preferably formed by the notch of length limited, parallel stretching, extension,
The notch is introduced into from each end in rolling bearing retainer.Here, it is cut by connection sheet by what near-earth relative to each other stretched
Mouth separates, however wherein connection sheet is connected to rolling bearing retainer in the end of rolling bearing retainer by root respectively
Material on.Thus obtain：Corresponding notch is compared with starting from another notch of opposite axial end side from rolling bearing
Or the axial end side of retainer acts the root for extending up to connection sheet, and thus the axis of rolling is not fully separated along ring circumferential direction
Hold retainer.Herein preferably, width of each notch in ring circumferential direction is corresponded to along the connection sheet width of ring circumferential direction.
Advantageously, rolling bearing according to the present invention provides following feasibility：Rolling bearing retainer is radially-inwardly determined
To the edge outside that is locked to as catch edge inner ring circumferential groove in so that rolling bearing circle and inner ring are collectively form
Premounted unit and rolling bearing.In this manner, rolling bearing retainer include affiliated composition for the rolling element of needle roller and
Inner ring connects, and the rolling element forms needle roller circle.By the measure, which will not scatter during transportation.By in rolling bearing
The unit not only simplified operation in transport also referred to as KI that ring and rolling bearing retainer are formed, but also simplify installation.
In addition, the rolling bearing retainer formed according to the present invention can have the edge being radially outward directed, the side
Edge is locked in the circumferential groove of the inside of gear.Preferably, this rolling bearing retainer is supported designed for idle pulley, wherein lazy
Wheel compared with axis rotationally radial support in the transmission, especially in automatic transmission.
In order to improve the elasticity of the rolling bearing retainer formed according to the present invention, propose：It is provided with multiple ring week distributions
The connection chip lock piece that ground is set.To this preferably, rolling bearing includes three 120 ° of connection chips of offseting one from another respectively
Lock piece.When needed, connection chip can especially be further improved in the rolling bearing retainer for needing that there is major diameter
The quantity of lock piece.
A preferred design for connecting chip lock piece proposes：The connection chip lock piece is separated by connection sheet
Notch along rolling bearing retainer or rolling bearing longitudinal axis direction orient.The setting is for being designed for rolling element
Loading space of the pocket hole in rolling bearing retainer generate positive influences.
It is proposed according to the designing scheme in another structure：The rolling bearing retainer formed according to the present invention unilaterally prolongs
It is long, to form distance piece.It is here, associated with extension designed for axially firm edge.In addition, the present invention can convert
In the rolling bearing retainer of double composition, wherein retainer pocket hole is set with axially spaced two rows.Here, for axial
Firm edge is centrally arranged between the row of the first and second retainer pocket holes.In order to realize that it is affiliated that edge is most preferably matched with
Circumferential groove, propose：Circumferential groove is matched in different shapes forms edge.For example, edge can have it is trapezoidal, rectangle
Or semicircular cross-sectional profiles.
