Description
Technical field：
The utility model belongs to machinery manufacturing technology field, and in particular to a kind of full back arbor cages for needle.
Background technology：
Cages for needle can either accurately guide needle roller, and can keep the exact position of needle roller, therefore be widely used in
In the bearings in fields such as weight Transport Machinery, digger, constructional engineering machinery, harbour machinery, cages for needle generally passes through laser
After the processing methods such as cutting, Water Cutting and wire cutting obtain semi-finished product, then through the processing of the secondary operation such as turnning and milling, plane, mill, processing effect
Rate is low, and dimensional accuracy and the production process of product are difficult control, and working surface is relatively rough.The both sides in needle roller hole are due to existing
The milling cutter slot that milling leaves, causes small with needle roller contact area, and during work, the stability of needle roller is poor, in addition, existing needle roller is protected
Frame is held also to there is technical issues that.
The content of the invention：
The purpose of this utility model is to overcome above-mentioned the shortcomings of the prior art part, and provide a kind of Rigid cutter
Handle cages for needle strengthens the stability of needle roller, improves the service life of retainer, reduces production cost.
In order to solve the problems existing in background technology, the utility model adopts the following technical solution：A kind of full back arbor
Cages for needle, including the butt joint ring that frame body and the needle roller hole being arranged on frame body, the frame body have opening for one, butt joint ring
One end be staggeredly equipped with dovetail tangs and dovetail groove orifice, the other end of butt joint ring is correspondingly arranged on dovetail groove orifice and dovetail is convex
It rises, the dovetail tangs of butt joint ring one end are adapted to docking with the dovetail groove orifice of the other end and form cricoid retainer, the ring of butt joint ring
Several needle roller holes are set on body, the rectangular shape in needle roller hole, the needle roller hole of rectangle with respect to ring body end slope, needle roller hole
The angle of side and ring body end face is 2 degree.
Preferably, 3-5 row's needle rollers hole, the needle roller hole staggered row of adjacent row are set in the width direction in the ring body of butt joint ring
Row.
Preferably, the frame body is the butt joint ring of irony.
Preferably, the surface of the frame body has wearing layer, and the wearing layer is plating titanium layer or copper plate or polytetrafluoroethyl-ne
Ene coatings.
Preferably, the surface of the frame body is equipped with phosphorization membrane, and the phosphorization membrane is iron manganese phospbate coating layer.
The butt joint ring that the utility model has opening for one, butt joint ring form cricoid needle roller using dovetail configuration through docking
Retainer, the stamped shaping in needle roller hole, manufacture craft is simple, and ferrous material can be used in the frame body, at low cost, is conducive to promote
Using；The needle roller hole of rectangle and needle roller contact area bigger, the stability of needle roller is strong, and using effect is good；The side in needle roller hole 6
Angle α with ring body end face is 2 °, and when inwardly tightening, circumferentially disposed needle roller forces collet body inwardly to become due to taper effect
Shape forms coupling mechanism force, generates sizable chucking power, and when cutter works, vibrations, while this will not be generated due to high speed rotates
Utility model has good wearability and corrosion resistance, effectively extends service life.
Description of the drawings：
Fig. 1 is to maintain the overlooking the structure diagram of frame；
Fig. 2 is the A-A of Fig. 1 to schematic cross-sectional view；
Fig. 3 is the deployed configuration schematic diagram of butt joint ring；
Fig. 4 is the partial enlargement structural representation of Fig. 3.
In figure：1. retainer, 2. butt joint rings, 3. dovetail groove orifices, 4. dovetail tangs, 5. needle rollers, 6. needle roller holes.
Specific embodiment：
With reference to Fig. 1-4, a kind of full back arbor cages for needle is described including frame body and the needle roller hole 6 being arranged on frame body
The butt joint ring 2 that frame body has opening for one, one end of butt joint ring 2 is staggeredly equipped with dovetail tangs 4 and dovetail groove orifice 3, butt joint ring 2
The other end be correspondingly arranged on dovetail groove orifice 3 and dovetail tangs 4, the dovetail tangs 4 of 2 one end of butt joint ring and the dovetail groove of the other end
3 adaptation docking of mouth forms cricoid retainers 1, and the utility model is docked by butt joint ring using dovetail configuration, Peripheric locking；
The stamped shaping in needle roller hole, manufacture craft is simple, and the frame body is the butt joint ring 2 of irony, at low cost, is conducive to promote and apply.
4 row's needle roller holes 6 are set in the width direction in the ring body of butt joint ring 2, and the needle roller hole 6 of adjacent row is staggered, described
6 rectangular shape of needle roller hole, the end slope of the opposite ring body in needle roller hole 6 of rectangle, the side in needle roller hole 6 and the angle of ring body end face
α is 2 °.The 6 stamped shaping of needle roller hole, there is no milling cutter slot, the needle roller hole 6 of rectangle is contacted with needle roller 5 for the two sides in needle roller hole 6
Area bigger, in needle roller hole 6 can 5 pieces of needle rollers placed side by side, the stability of needle roller 5 is strong, and using effect is good.
When lock sleeve rotates clockwise retainer 1 and needle roller 5 is driven to rotate, when needle roller 5 falls into the slot on collet body by
In guiding role retainer 1 is forced to tilt, continuing rotary locking cover makes needle roller 5 move that retainer 1 is driven to act together, shape
Moved upwards into spiral, since the upper side edge in needle roller hole 6 and the horizontal direction of ring body are in 2 degree of angles, circumferentially disposed needle roller 5 by
In taper effect collet body is forced to be deformed inward, form coupling mechanism force, generate sizable chucking power, it, will not when cutter works
Vibrations are generated due to high speed rotates, cutter counter-clockwise helical unclamps downwards.
The surface of the frame body has wearing layer, and the wearing layer is to plate titanium layer or copper plate or polytetrafluorethylecoatings coatings,
Effectively evade the problem of needle roller hole is easy to wear, effectively improve the service life of class retainer.
The surface of the frame body is equipped with phosphorization membrane, and the phosphorization membrane is iron manganese phospbate coating layer, can prevent needle roller
The surface in hole is corroded, and the phosphorization membrane compact crystallization of formation reduces 6 surface roughness of needle roller hole.
