Description
Technical field
The utility model relates to a kind of retainer more particularly to a kind of gloomy base Mir bearing retainers, belong to retainer skill
Art field.
Background technique
With the fast development of home and abroad steel industry, for the rolling requirements for adapting to high-precision, high strength cold-rolled plate,
High-accuracy Sendzimir bearing requirements are higher and higher；Currently, there are huge with foreign countries for domestic high-accuracy Sendzimir bearing
Gap, the external import of Sendzimir bearing 90%, to fast implement high-accuracy Sendzimir bearing production domesticization import substitution,
It is particularly important with three ribs, the high-accuracy Sendzimir bearing of the biserial cylinder with retainer to study outer ring, but has rib
Biserial cylindrical bearing, due to retainer, assembly difficulty, the cylindrical bearing not high to precision, traditional assembly method
It is also possible that but for high-accuracy sendzimir mill bearing, this method necessarily causes the loss of bearing accuracy, while bearing rolls
Necessarily there is scuffing in road, and the service life of bearing will also decline, therefore, it is necessary to invent a kind of novel retainer, solves this problem；For
This, Chinese Patent Application No.: 201020591636.5, disclose a kind of prong-shaped cage for Sendzimir bearing.The guarantor
Double segment type retainer pocket pore structure shapes that frame adds straight line with circular arc are held, pocket hole shape is being not single circular arc pocket hole, and
It is the combining form of a part of circular shape and a part of rectilinear form, the depth in pocket hole is shallowly staggered using one deep one；This
The beneficial effect of utility model is, 1. by retainer, commonly single circular arc pocket pore structure is changed to " circular arc adds the double sections of straight line " type knot
Structure, when assembly, roller can be packed into from retainer internal diameter, avoided raceway and be scratched, and ensure that precision and the service life of bearing；
2. the depth in pocket hole ensure that the axial motion of retainer, it is often more important that improve using a deep shallow staggered form
Lubrication, bearing when rotating at high speed, avoid abrasion and temperature rise are excessively high, improve bearing life and stability；But its structure is steady
It is qualitative not good enough, and roller oil-containing effect is poor.
Utility model content
A kind of in order to solve the above problems, the utility model proposes gloomy base Mir bearing retainer, guiding performance is good, rolling element
It is uniformly distributed stress；And whole high lubricating effect.
The enclosed frame body and one in closed pocket hole is arranged including interval for the gloomy base Mir bearing retainer of the utility model
Body is made in enclosed frame body both ends, and the half-closed frame body in open pocket hole is arranged in interval；The closed pocket hole and open pocket
The setting of hole interleaved；Open pocket hole described in upper and lower side is staggered；Retainer setting is structure as a whole, using by enclosed frame
Body and half-closed frame body are made into integration, and form semi-open-closing-semi-open structure；It improves structure with good guiding performance
Stability, meanwhile, avoid the rolling element group of existing separate structure from interfering, rolling element is uniformly distributed stress；It is described closed
Pocket hole and its lintel corner of open pocket hole are indent arc chord angle；It can be avoided closed pocket hole and open pocket hole lintel turn
Angle is interfered with roller, and the stress for utmostly reducing corner is concentrated, and the closed pocket hole includes one from the inside to the outside
Manufactured linear type pocket hole and arc-shaped pocket hole；The closed pocket hole transversal cross-section is that circular arc and straight line are tangent；It assembles in this way
When, roller can be packed at linear type pocket hole from retainer internal diameter direction, avoided scuffing of the roller to raceway, be ensure that axis
The precision held and service life；The closed pocket depth is greater than roller axial length, can be improved roller axial direction freedom of motion
Degree；The open pocket hole end surface is arc pocket；Interior fore shaft has been made into integration on the inside of the arc pocket；The arc pocket
Outside has been made into integration outer fore shaft；The outer fore shaft within angle is 60 °；The interior fore shaft within angle is 30 °；Open pocket hole is
Roller must not be dropped out after the indentation of outer fore shaft from interior fore shaft, and guarantee retainer and maximum by the frame mode of inside and outside twin-lock mouth
The combination physical efficiency of size roller easily passes the outer internal diameter of minimum of outer ring.
As preferred embodiment, the enclosed frame body and half-closed frame body outer surface are in closed pocket hole and open
Pocket hole periphery offers a ring outer oil sump, can carry out roller oil-containing and lubrication to roller surface outside retainer.
As preferred embodiment, the enclosed frame body and half-closed frame body inner surface are in closed pocket hole and open
Pocket hole periphery offers a ring inner oil sump；It can carry out roller oil-containing and lubrication to roller surface inside retainer.
Further, the outer oil sump and inner oil sump section are ramp structure；The outer oil sump and inner oil sump bottom surface and envelope
Enclosed pocket hole and open pocket hole edge are in same plane.
Compared with prior art, the gloomy base Mir bearing retainer of the utility model, by the retainer of existing separate structure
Setting is structure as a whole, and is made into integration using by enclosed frame body and half-closed frame body, forms semi-open-closing-semi-open structure；
It improves structural stability with good guiding performance, meanwhile, it avoids the rolling element group of existing separate structure from interfering, rolls
Kinetoplast is uniformly distributed stress；When installation, end roller is directly packed into open pocket hole from end or inside, and mediate roller is from interior
Portion is packed into closed pocket hole, can either complete roller guiding and self-locking, while preventing plowing from raceway, mediate roller can on
Lower slider can improve lubricant effect, can complete roller oil-containing by outer oil sump and inner oil sump and edge keeps off oil, improve and continue
Property lubrication.
