Description
[technical field]
The utility model relates to experimental branch line technical fields, and in particular to a kind of dacron thread transition wheel.
[background technique]
Transition wheel is to be installed in outside bearing, and when silk, line are walked in slot inner surface out-of-date, line wheel is rotated with silk, line, from
And sliding friction is converted into static friction, transition wheel technology is all employed in many fields at present.
Existing dacron thread transition wheel is all shorter in use cost and service life, after long-time is using transition wheel, U-shaped wheel
Because friction will lead to certain abrasion, at this moment transition wheel can only integrally be changed, using new transition wheel, and the axis of transition wheel
It holds and has friction at work with steel ball, the meeting being difficult to avoid that rubs generates certain iron filings, and iron filings can be to the rotation of transition wheel
The problem of certain frictional force can be generated, the service life of transition wheel can be reduced, thus it is proposed that a kind of dacron thread transition wheel.
[utility model content]
Entirety is not necessarily to more after U-shaped wheel is frayed to solve the above problems, the purpose of this utility model is to provide one kind
It changes, to reduce cost, and is avoided that the dacron thread transition wheel that iron filings have an impact the rotation of transition wheel.
To achieve the above object, the technical solution that the utility model is taken are as follows: dacron thread transition wheel, including U-shaped wheel and axis
Body is held, the U-shaped wheel is provided centrally with bearing hole, and bearing body is arranged in bearing hole, and the length of bearing body is less than bearing hole
Length, the bearing body includes outer bearing body, inner bearing body and the steel ball being arranged between outer bearing body and inner bearing body, interior
The center of bearing body is to wear axis hole, and the side of U-shaped wheel is provided with cover board, and cover board is provided centrally in corresponding with axis hole is worn
Heart hole, cover board are connected with U-shaped wheel by the first screw, are formed in bearing hole between the inner wall of cover board and the side wall of bearing body
Bits chamber is set, multiple second screws, side wall of the top of the second screw after setting bits chamber with outer bearing body are additionally provided on cover board
It is inconsistent, multiple discharging openings are provided on cover board, discharging opening is located at the joint place of bearing hole and cover board.
Dacron thread transition wheel in the utility model is further arranged to: the bearing hole is that a lateral aperture is small, the other side
The big bell mouth shape in aperture, the outer wall of the outer bearing body be it is with matching round table-like, the cover board is located at bearing hole
Large aperture side.
Dacron thread transition wheel in the utility model is further arranged to: the discharging opening is with the central axes of bearing hole along ring
To being uniformly distributed.
Compared with prior art, it the utility model has the following beneficial effects: above-mentioned dacron thread transition wheel, uses point
The structure of body formula makes to be dismantled between U-shaped wheel and bearing body, can be only to U when the surface of U-shaped wheel is worn
Type wheel is replaced, without replacing bearing body, to reduce costs.In addition, the fitting surface between its U-shaped wheel and bearing body
Using inclined-plane, when generating iron filings in steel ball work, iron filings can be discharged from discharging opening, avoid the rotation to transition wheel and generate
It influences, improves the service life of transition wheel.
[Detailed description of the invention]
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the schematic cross-sectional view of the utility model；
In figure: 1, U-shaped wheel, 2, bearing hole, 3, outer bearing body, 4, inner bearing body, 5, steel ball, 6, wear axis hole, 7, cover board, 8,
Centre bore, the 9, first screw, 10, set bits chamber, 11, discharging opening, the 12, second screw.
[specific embodiment]
Dacron thread transition wheel described in the utility model is described in further detail below by specific embodiment.
As shown in Figure 1 and Figure 2, dacron thread transition wheel, including U-shaped wheel 1 and bearing body, the U-shaped wheel 1 are provided centrally with
Bearing hole 2, bearing body are arranged in bearing hole 2, and the length of bearing body is less than the length of bearing hole 2, and the bearing body includes outer
Bearing body 3, inner bearing body 4 and the steel ball 5 being arranged between outer bearing body 3 and inner bearing body 4, the center of inner bearing body 4 are to wear
The side of axis hole 6, U-shaped wheel 1 is provided with cover board 7, and cover board 7 is provided centrally with centre bore 8 corresponding with axis hole 6 is worn, cover board 7
It is connected by the first screw 9 with U-shaped wheel 1, is formed in bearing hole 2 between the inner wall of cover board 7 and the side wall of bearing body and set bits
Chamber 10 is additionally provided with multiple second screws 12 on cover board 7, the top of the second screw 12 passes through set bits chamber 10 after with outer bearing body 3
Side wall it is inconsistent, multiple discharging openings 11 are provided on cover board 7, discharging opening 11 is located at the joint place of bearing hole 2 and cover board 7.Institute
Discharging opening 11 is stated circumferentially to be uniformly distributed with the central axes of bearing hole 2.The bearing hole 2 is that a lateral aperture is small, another lateral aperture
