Description
Technical field
The utility model belongs to bearing correlative technology field, more particularly to a kind of retainer.
Background technology
It is well known that retainer is one of important component of rolling bearing, it is to guide to roll in bearing working that it, which is acted on,
Body runs well, and keeps rolling element not depart from bearing at any time.In addition, in order to obtain preferable operating condition or mounting bar
Part, retainer typically need also control rolling element with respect to the free movement of retainer, rolling element can neither be limited narrow so that
Can not freely it rotate, can not be excessively loose so that assembling or installation difficulty.Generally, retainer be by constrain roll external surface come
Rolling element is kept not depart from, the outer surface is ball surface to ball bearing speech, is outer round surface to roller bearing speech, is all in a word
The load-bearing surface or working surface of rolling element, so inevitably working surface is had an impact when effect of contraction occurs,
Such as lubricant flow direction, abrasion difference, so as to influence the performance and used life of bearing.
In order to control the free movement of rolling element, the retainer of above-mentioned hold mode has quite in design and manufacture to precision
High requirement, cost are higher.It is different from ball bearing, for roller bearing, including cylinder roller bearing, taper roll bearing, ball
Face roller bearing, additional geometric element, such as depression, hole can be produced in roller end, by constraining the additional geometry member
Plain surface keeps roller.At present, geometric element surface is added to keep the retainer of roller to have punching rolling by constraining roller
Sub- retainer, punching press protrusion lock point retainer.Punching roller retainer needs to bore a through hole on roller, influences roller intensity,
And because roller mandrel is acted on by power all the time in operation, once serious consequence will be produced by releasing, so to retainer
Design, manufacture and matching requirements it is higher, complicated and accurate operation is so needed, so as to increase job costs.
Utility model content
Problem to be solved in the utility model is to provide a kind of retainer, and the retainer is follow-up bearing in structure
The lock point that constraint roller is stamped out in assembling provides condition, and this way of restraint does not disturb not only, influenceing bearing just completely
Often operating, and it is simple in construction, and required precision is relatively low.
To reach above-mentioned purpose, technical scheme is used by the utility model solves above-mentioned technical problem:One kind is kept
Frame, including frame body, the frame body include the first side ring, the second side ring and several be arranged between the first side ring and the second side ring
Lintel, first side ring is connected by lintel with the second side ring, and it is mutually right to be offered positioned at the forward and backward both ends of the lintel
Claim the groove set, the groove interlude is arcuate structure.
Further, attachment means are also equipped with the frame, the attachment means include mounting seat and connection fixture block, institute
The upper surface that mounting seat is arranged on the first side ring is stated, the connection fixture block is arranged on the side surface of the first side ring, the mounting seat
It is equipped with being connected fixture block.
Further, offered in the mounting seat and offer card on fixture block in funnelform open slot, described connect
Catching groove, the open slot connect with buckle slot.
Further, the lintel includes the first closing piece, the second closing piece and fore shaft block, first closing piece and the second closing piece point
Fore shaft block upper/lower terminal is not arranged on, and described lintel one end is connected by the second closing piece with the first side ring, the lintel other end
By the first closing piece, the groove is arranged on fore shaft block.
Further, the curved structure of first side ring and the second side ring.
Further, U-lag is provided with positioned at the buckle slot, the U-lag is located at the madial wall both ends open of buckle slot.
Compared with prior art, the technical solution of the utility model has the following advantages that：
1st, a kind of retainer provided by the utility model, its retainer are punching press in follow-up bearing assembling in structure
The lock point for going out to constrain roller provides condition, and this way of restraint does not disturb, influenceed the normal operation of bearing not only completely, and
Simple in construction, required precision is relatively low.
2nd, the groove being symmetrically set is offered at the forward and backward both ends of lintel, the groove interlude is arcuate structure,
Such setting can effectively avoid causing roller can not be very well in retainer because the coefficient of friction on retainer is larger
Upper work.
3rd, offered in mounting seat in funnelform open slot, described connect offers buckle slot on fixture block, described to open
Mouth groove connects with buckle slot, is so easy to retainer to be connected after roller is installed with other parts.
