Embodiment
Embodiment one：
As shown in figure 3, the utility model provides a kind of plastic circular loom door circle roll wheel assembly, including shaft 4 and roller
5, shaft 4 is connected on a coil assembly, and roller 5 is connected by bearing 6 with shaft 4, and roller 5 includes colloid 51 and steel bushing 52, glue
Body 51 is located at 52 periphery of steel bushing, and steel bushing 52 coordinates with bearing 6, and the upper end of steel bushing 52 is higher by colloid 51, is located at roller 5 in shaft 4
It is fixedly arranged above dustproof cover 7, is equipped with the first dust-proof cushion 71 in dustproof cover 7, it is interior and be against that dustproof cover 7 is stretched into the upper end of steel bushing 52
On one dust-proof cushion 71.
The utility model covers the upper end of roller 5 by dustproof cover 7, prevents dust from falling directly into 6 gap of bearing, and anti-
First dust-proof cushion 71 is set in dirt lid 7, and is propped up by steel bushing 52, further stops what is arbitrarily drifted using the first dust-proof cushion 71
Dust enters 6 gap of bearing, while the upper end of steel bushing 52 is stretched into dustproof cover 7, can form mazy passage, and dust needs elder generation
6 gap of bearing can be just downwardly into by moving across the upper end of steel bushing 52 upwards, and dust once enters in dustproof cover 7, due to anti-
Atmosphere draught-free in dirt lid 7, will be easy to run out of steam.Naturally it cannot be introduced into steel bushing 52, will not more enter between bearing 6
Gap, so as to fulfill extraordinary dust-proof effect.In addition, propping up the first dust-proof cushion 71 using steel bushing 52, the thickness of steel bushing 52 is smaller,
Small with the contact area of the first dust-proof cushion 71, steel bushing 52 will not be influenced when rotating by fixed first dust-proof cushion 71, really
The normal function for protecting roller 5 is unaffected.
In order to further improve dust-proof effect, the second dust-proof cushion 53 is equipped with steel bushing 52, the second dust-proof cushion 53 is located at bearing 6
Top, has the first gap 50 between the second dust-proof cushion 53 and the first dust-proof cushion 71.Since the rotation of roller 5 can produce heat, institute
Risen with the air pressure inside steel bushing 52, the air in the first gap 50 will produce what is outwards flowed through the first dust-proof cushion 71
Trend, further prevents dust from entering steel bushing 52, so that dust-proof effect is improved, further, since the second dust-proof cushion 53 is revolved with roller 5
Turn, and the first dust-proof cushion 71 is fixed, so both do not contact, 53 rotary motion of the second dust-proof cushion is unaffected.
In the present embodiment, the upper end that the periphery of shaft 4 is located at roller 5 is cased with Upper shaft sleeve 41, and Upper shaft sleeve 41 stretches into steel bushing 52
The inner ring top axial of bearing 6 is positioned, dustproof cover 7 is fixed on 41 periphery of Upper shaft sleeve, and Upper shaft sleeve 41 can improve damped coefficient,
Be conducive to dustproof cover 7 to fix, while simplify 4 structure of shaft, shaft 4 can be directly using the constant optical axis of diameter, and second is dust-proof
Pad 53 and 41 clearance fit of Upper shaft sleeve, when rotation, are unaffected.
Rotated in order to avoid dustproof cover 7 influences roller 5, between the inner circumferential side of dustproof cover 7 and the circumferential lateral surface of steel bushing 52
With the second gap 70, the lower face of dustproof cover 7 is higher than the upper surface of colloid 51.
On the basis of said structure, dust-proof effect can be further improved, i.e., the is equipped with the lower end of steel bushing 52
Three dust-proof cushions 54, shaft 4 are equipped with the fixing piece 8 that the 3rd dust-proof cushion 54 of support avoids dropping.The machine moved upwards due to dust
Rate is smaller, so the dust-proof of 6 lower end of bearing can be achieved by the simple protection of the 3rd dust-proof cushion 54.
Fixing piece 8 in the present embodiment does not rotate, in order to reduce the contact area with the 3rd dust-proof cushion 54, fixing piece 8
Upper surface is equipped with convex ribs 81, and fixing piece 8 is contacted by convex ribs 81 and supports the 3rd dust-proof cushion 54.Convex ribs 81 can use ring junction
Structure, can also subsection setup.Since fixing piece 8 only needs to hold the 3rd dust-proof cushion 54, can control fixing piece 8 with
The spacing of roller 5 avoids having an impact the rotation of roller 5.And in order to avoid fixing piece 8 is contacted with roller 5, the outside diameter of fixing piece 8
Less than the internal diameter of steel bushing 52.It should be understood that fixing piece 8 can also rotate to be located in shaft 4.
Similar with Upper shaft sleeve 41, the lower end that the periphery of shaft 4 is located at roller 5 is cased with Lower shaft sleeve 42, and Lower shaft sleeve 42 stretches into
The inner ring lower end axially position of bearing 6, fixing piece 8 are fixed on 42 periphery of Lower shaft sleeve, the 3rd dust-proof cushion 54 and lower axle by steel bushing 52
Cover 42 clearance fits.
In the present embodiment, two bearings 6 are equipped with steel bushing 52, are positioned between the inner ring of two bearings 6 by spacer 43, axis
The outer ring for holding 6 then carries out axially position by the shaft block ring 55 being located in steel bushing 52.
In addition, in order to improve the fixed effect of dustproof cover 7, screw hole 01 can be beaten in the side of dustproof cover 7, trip bolt with
Lock is in shaft 4 or Upper shaft sleeve 41 after the cooperation of screw hole 01 is tightened.Fixing piece 8 similarly can set screw hole 01 to carry out by force in side
Change and fix.
