Abstract
The utility model discloses a kind of double needle with round ends, including needle roller ontology, needle roller ontology middle section is provided with needle roller roller body, the needle roller roller body is cylindrical body roller bearing, it is smooth arc face on the outside of the needle roller roller body, needle roller ontology both ends come directly towards equipped with needle roller, needle roller top inner end is connect with the needle roller roller body integral type, needle roller top lateral surface is protrusion arc face, the protrusion arc face top in needle roller top outside offers cross strangle streakline slot, and the cross strangle streakline geosynclinal concave falls into the surface of the needle roller top and opening up.Through the above way, the utility model has good stability, needle roller ontology both ends designed arc-shaped appearance can play the role of good shock-absorbing destressing after being assembled to cages for needle, and cross strangle streakline slot is offered on the needle roller top at needle roller ontology both ends, CONTACT WITH FRICTION can be increased when needle roller comes directly towards and touches cages for needle, the skidding dislocation of needle roller top is avoided to drop out cages for needle.
Description
Technical field
The utility model relates to field of bearings, more particularly to a kind of double needle with round ends.
Background technique
Needle bearing is the roller bearing with cylindrical roller, its opposite diameter, and roller was not only thin but also long.This roller is known as rolling
Needle.Although having lesser section, bearing load-taking capacity still with higher, needle bearing long roller equipped with thin
(roller diameter D≤5mm, L/D >=2.5, L are roller length), therefore radial structure is compact, internal diameter and load-carrying ability with
When other types of bearings are identical, minimum outer diameter, the supporting structure especially suitable for the size-constrained system of radially installed.But traditional rolling
Needle is flush configuration, and both ends end face is horizontal plane, is easy to strike in needle roller stress and damages situation on retainer, is reduced
Service life.
Utility model content
The utility model can have good stabilization mainly solving the technical problems that providing a kind of double needle with round ends
Property, needle roller ontology both ends designed arc-shaped appearance can play the role of good shock-absorbing destressing, cross strangle line after being assembled to cages for needle
Wire casing can increase CONTACT WITH FRICTION when needle roller comes directly towards and touches cages for needle, and the skidding dislocation of needle roller top is avoided to drop out needle roller guarantor
Hold frame.
In order to solve the above technical problems, the technical solution that the utility model uses is: a kind of double needle with round ends are provided,
Including needle roller ontology, needle roller ontology middle section is provided with needle roller roller body, and the needle roller roller body is cylindrical body roller bearing, described
Be smooth arc face on the outside of needle roller roller body, needle roller ontology both ends are equipped with needle roller and come directly towards, the needle roller top inner end and
The needle roller roller body integral type connection, needle roller top lateral surface is protrusion arc face, convex on the outside of the needle roller top
It plays arcwall face top and offers cross strangle streakline slot, the cross strangle streakline geosynclinal concave falls into the surface of the needle roller top and opening up.
In one preferred embodiment of the utility model, needle roller top protrusion height is 1-3mm.
In one preferred embodiment of the utility model, the cross strangle streakline groove depth is 0.2-0.8mm.
The beneficial effects of the utility model are: the utility model has good stability, needle roller ontology both ends circular arc is set
Meter can play the role of good shock-absorbing destressing after being assembled to cages for needle, and open on the needle roller top at needle roller ontology both ends
Equipped with cross strangle streakline slot, CONTACT WITH FRICTION can be increased when needle roller comes directly towards and touches cages for needle, needle roller top is avoided to skid
Dislocation drops out cages for needle.
Detailed description of the invention
It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model
Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings
Obtain other attached drawings, in which:
Fig. 1 is the structural schematic diagram of the utility model one preferred embodiment of double needle with round ends；
Fig. 2 is the structural schematic diagram that shown needle roller comes directly towards a preferred embodiment；
The components in the drawings are labeled as follows: 1, needle roller ontology；2, needle roller roller body；3, needle roller comes directly towards；4, cross
Twist streakline slot.
Specific embodiment
Below by the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described
Embodiment is only a part of the embodiment of the utility model, instead of all the embodiments.Based on the implementation in the utility model
Example, all other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
Fig. 1 and Fig. 2 are please referred to, the utility model embodiment includes:
A kind of double needle with round ends, including needle roller ontology 1,1 middle section of needle roller ontology is provided with needle roller roller body 2, described
Needle roller roller body 2 is cylindrical body roller bearing, is smooth arc face on the outside of the needle roller roller body 2,1 both ends of needle roller ontology are equipped with
Needle roller top 3, the needle roller comes directly towards 3 inner ends and connect with 2 integral type of needle roller roller body, and the needle roller comes directly towards 3 lateral surfaces
Protrusion arc face top for protrusion arc face, 3 outside of needle roller top offers cross strangle streakline slot 4, the cross strangle
Streakline slot 4 is recessed into 3 surfaces of the needle roller top and opens up.
In addition, it is 1-3mm that the needle roller, which comes directly towards 3 protrusion heights,.
In addition, 4 depth of cross strangle streakline slot is 0.2-0.8mm.
The working principle of the utility model is that 1 middle section of needle roller ontology is provided with needle roller roller body 2, and needle roller roller body 2 is circle
Cylinder roller bearing, is smooth arc face on the outside of needle roller roller body 2, and 1 both ends of needle roller ontology are equipped with needle roller top 3,3 inside of needle roller top
End is connect with 2 integral type of needle roller roller body, and it is protrusion arc face that needle roller, which comes directly towards 3 lateral surfaces, and it is 1- that needle roller, which comes directly towards 3 protrusion heights,
The protrusion arc face top of 3mm, 3 outside of needle roller top offer cross strangle streakline slot 4, and cross strangle streakline slot 4 is recessed into needle roller
It comes directly towards in 3 surfaces and opens up, 4 depth of cross strangle streakline slot is 0.2-0.8mm, and needle roller ontology 1 has good stability, needle roller sheet
1 both ends designed arc-shaped appearance of body can play the role of good shock-absorbing destressing, and 1 both ends of needle roller ontology after being assembled to cages for needle
Needle roller top 3 on offer cross strangle streakline slot 4, can needle roller come directly towards 3 touch cages for needle when increase CONTACT WITH FRICTION,
The 3 skidding dislocation of needle roller top is avoided to drop out cages for needle.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Using equivalent structure or equivalent flow shift made by the utility model description, it is applied directly or indirectly in other phases
The technical field of pass, is also included in the patent protection scope of the utility model.
