Abstract
The invention relates to a shuttle wheel, in particular to a dust-proof shuttle wheel capable of preventing dust from entering a bearing. The dust-proof shuttle wheel comprises an iron core, polyurethane, a small hollow shaft, a bearing and a retainer ring for a hole, wherein the polyurethane is coated on the outer circle of the iron core; the retainer ring for the hole is used for axially locating the bearing; the bearing is sleeved on the small shaft; the bearing is in transitional fit with the cavity of the iron core; a bolt penetrates into the small shaft and is connected with the small shaft by a screw thread; the cavity of the iron core close to the head part of the bolt is provided with an annular boss; a dust cover covers above the boss; the small shaft close to the hole retainer ring is provided with a dustproof flange; and a gasket is mounted between downside of a screw cap of the bolt and the bearing. The dustproof flange is additionally arranged on the original small shaft and a dustproof cover is also additionally arranged so that the dust is effectively prevented from entering the bearing of the shuttle wheel; therefore, the service life of the shuttle wheel is prolonged, the production cost is saved and the production efficiency is increased.
Description
Technical field
The present invention relates to a kind of shuttle wheel, particularly a kind of dust that can prevent gets into the dustproof shuttle wheel in the bearing.
Background technology
The shuttle wheel generally is used for the shuttle of weaving loom, and the mach raw material of weaving are mainly line, silk, fiber crops etc., and these raw material can produce more dust fibre in fabrication processes.Shuttle is taken turns running under this working environment, and those dust can enter into the bearing in the shuttle wheel, because there is lubricant grease bearing inside, so just bonds with lubricant grease behind these dust entering bearing inside; After a period of time, dust is cumulative, and dust has just been filled up in bearing inside, causes bearing stuck; The shuttle wheel does not rotate, and just must shut down more shuttle changing wheel this moment, and processing can not be carried out in serialization, has wasted the production time; And the shuttle wheel is short service life, often needs to change, and has increased production cost.
Summary of the invention
The technical problem that the present invention will solve is: solve existing shuttle wheel and get into dust easily, cause the bearing in the shuttle wheel stuck, the shuttle wheel often needs to change, the technical problem that service life is short.The present invention provides a kind of dustproof shuttle wheel, and it has been through having added dustproof flange on original little axle, and has increased a dust cap; Stop that effectively dust gets in the bearing of shuttle wheel; Improve the service life of shuttle wheel, practiced thrift production cost, improved productivity effect.
The technical solution adopted for the present invention to solve the technical problems is: a kind of dustproof shuttle wheel; Back-up ring is used in the hole that has iron core, is coated on the polyurethane of iron core cylindrical, hollow little axle, bearing and is used for the bearing axial location; Bearing holder (housing, cover) is contained on the hollow little axle, and bearing and iron core inner chamber interference fits are equipped with bolt in the hollow little axle; Bolt is connected with hollow little male thread; The iron core inner chamber is provided with annular boss near the bolt head place, and dust cap is stamped in the top of annular boss, and described hollow little axle has dustproof flange near the hole with the back-up ring place.
In order to protect bearing cone, between the nut below of described bolt and the bearing packing ring is housed.
The invention has the beneficial effects as follows: this dustproof shuttle wheel through on original little axle, having added dustproof flange, and has increased a dust cap; Stop that effectively dust gets in the bearing of shuttle wheel; Improve the service life of shuttle wheel, practiced thrift production cost, improved productivity effect.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Fig. 1 is the structural representation of the specific embodiment of dustproof shuttle wheel of the present invention.
Among the figure: 1, iron core 2, polyurethane 3, hollow little axle 4, bearing 5, hole are with back-up ring 6, bolt 7, boss 8, dust cap 9, flange 10, packing ring
The specific embodiment
Of the present invention dustproof shuttle wheel specific embodiment as shown in Figure 1, a kind of dustproof shuttle wheel, the hole that has iron core 1, is coated on polyurethane 2, hollow little axle 3, the bearing 4 of iron core 1 cylindrical and is used for bearing 4 axial location is with back-up ring 5; Bearing 4 is sleeved on the hollow little axle 3; Bearing 4 and iron core 1 inner chamber interference fits are equipped with bolt 6 in the hollow little axle 3, and bolt 6 is threaded with hollow little axle 3; Iron core 1 inner chamber is provided with annular boss 7 near bolt 6 nut places; Dust cap 8 is stamped in the top of annular boss 7, and hollow little axle 3 has dustproof flange 9 near the hole with back-up ring 5 places, between the nut below of bolt 6 and the bearing 4 packing ring 10 is housed.
During work, airborne dust is a lot, and the shuttle wheel rotates under this working environment; Be easy to dust and enter in the bearing in the iron core, above bearing, established a dust cap now, effectively stopped the entering of dust; For the sealing effectiveness that makes bearing better; Also be provided with dustproof flange at hollow little axle below near bearing, it is inner to prevent that effectively dust from getting into bearing from the lower end, makes bearing stuck.
With above-mentioned foundation desirable embodiment of the present invention is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
