Technical field
Technical field of textile machine is the utility model is related to, more particularly, to a kind of yarn feeder guide roller of circular knitting machine.
Background technology
At present, conventional yarn feeder guide roller of circular knitting machine, mainly it is made up of bearing (ball) cover, bearing, guide wheel body, bearing causes
Guide wheel rolling friction is small, rotates flexibly and easily, but complicated and cost is high, and bearing is easily by yarn in workshop
Silk, the influence of lint, service life is low to be easily damaged, it is necessary to often change, wasting manpower and material resources, and maintenance cost is high, is badly in need of changing
Enter.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of yarn feeder guide roller of circular knitting machine,
Simple in construction, cost is low, and rolling friction is small, rotates flexibly and easily, and service life is high, and maintenance is simple and convenient, economical and practical.
To reach above-mentioned purpose, the technical solution of the utility model is：A kind of yarn feeder guide roller of circular knitting machine, including guide wheel sheet
Body, roller bearing, guide wheel shaft, the guide wheel body left side home position are provided with the axis hole that left and right directions runs through, the guide wheel body
Left side circumference uniform distribution is provided with the circular hole that several left and right directions run through, and the circular hole forms breach on shaft hole inner wall, described
The keyway that left and right directions runs through is provided with the top of circular hole, the roller bearing couples with circular hole interference fits and both ends exceed guide wheel sheet respectively
Body or so end face equal length, the key provided with strip joins the roller bearing crown center with keyway interference fit along its length
Connect, the roller bearing both ends are half sphere shape, and the guide wheel body both sides are arranged with guide wheel shaft, and the guide wheel shaft is convex post
Body structure, the guide wheel shaft leading portion cylinder couple until convex shoulder face and half sphere shape are tangent with the tangent cooperation of roller bearing.
The key and keyway equal length.
The roller bearing is made up of polytetrafluoroethylmaterial material.
The guide wheel shaft leading portion cylinder outer wall and convex shoulder face are equipped with polytetrafluorethylecoatings coatings.
The beneficial effects of the utility model are：The utility model is simple in construction, eliminates parts of bearings, substantially reduces into
This, in light weight, convenient disassembly, and be rolling friction between guide wheel body and guide wheel shaft, friction is small, rotates flexibly and easily, makes
High with the life-span, maintenance is simple and convenient, can remove direct washing, remove replacing maintenance cost from, economical and practical, is worthy to be popularized.

Embodiment
Below by embodiment, and with reference to accompanying drawing, the technical solution of the utility model is described in further detail.
As shown in Figure 1 to 4, a kind of yarn feeder guide roller of circular knitting machine, including guide wheel body 1, roller bearing 2, guide wheel shaft 3, it is described
The left side home position of guide wheel body 1 is provided with the axis hole 11 that left and right directions runs through, and the left side circumference uniform distribution of guide wheel body 1 is set
There is the circular hole 12 that several left and right directions run through, the circular hole 12 forms breach 13 on the inwall of axis hole 11, and the circular hole 12 pushes up
Portion is provided with the keyway 14 that left and right directions runs through, and the roller bearing 2 couples with the interference fits of circular hole 12 and both ends exceed guide wheel sheet respectively
The end face equal length of body 1 or so, the crown center of roller bearing 2 along its length with the interference of keyway 14 match somebody with somebody by the key 21 provided with strip
Connection is closed, the both ends of roller bearing 2 are half sphere shape 22, and the both sides of guide wheel body 1 are arranged with guide wheel shaft 3, the guide wheel
Axle 3 is convex column structure, and the leading portion cylinder of guide wheel shaft 3 couples until convex shoulder face and half sphere shape with the tangent cooperation of roller bearing 2
22 is tangent.
The key 21 and the equal length of keyway 14.
The roller bearing 2 is made up of polytetrafluoroethylmaterial material, and coefficient of friction is minimum, and self-lubricating property is good, good antistick characteristic,
It is corrosion-resistant, greatly improve service life.
The leading portion cylinder outer wall of guide wheel shaft 3 and convex shoulder face are equipped with polytetrafluorethylecoatings coatings, and coefficient of friction is minimum, from
Greasy property is good, good antistick characteristic, corrosion-resistant.
It the foregoing is only the preferable embodiment of the utility model, but the scope of protection of the utility model not office
It is limited to this, any one skilled in the art can readily occur in the technical scope that the utility model discloses
Change or replacement, it should all cover within the scope of protection of the utility model.
