Abstract
The invention discloses a friction-type false twister bearing which comprises an outer ring and a mandrel, wherein the outer ring is internally provided with an outer channel, two ends of the outer ring are provided with sealing grooves, and the mandrel is provided with an inner channel; a bearing retainer is positioned between the mandrel and the outer ring, the bearing retainer sleeves the mandrel, and a pocket hole of the bearing retainer is provide with a plurality of steel balls; the steel balls are matched with the inner channel of the mandrel and the outer channel of the outer ring, the sealing grooves of the outer ring are provided with sealing rings and sealing slices, and the outer end of a sealing ring on the mandrel is sleeved by a ferrule; the distance between the outer end surface of the ferrule and the synclastic end surface of the outer ring is H, and the mandrel of the outer end of the sealing slice is provided with a synchromesh gear. The friction-type false twister bearing has the advantages that the mandrel is directly provided with the synchromesh gear, the phenomenon that the synchromesh gear and the mandrel fall out is solved, meanwhile the quantity of synchromesh gear parts is lowered, the length of the mandrel is shortened, and the production cost is saved.
Description
Technical field
The present invention relates to a kind of stretch yarn machine chemical fibre special bearing, specifically, particularly a kind of friction twister bearing.
Background technique
Friction twister bearing is the critical component of high-speed stretch yarn machine, and friction twister bearing adopts the design of two ditch double row ball, and smooth running, carrying are large, how stacked or L-type sealing structure, good dustproof effect; Sorting is assembled, and fine balance, maximum speed can reach 20000 revs/min, has the features such as volume is little, good rigidly, noise are low, the life-span is long.Friction twister bearing is divided into active bearings and driven bearing, it comprises the parts such as outer ring, mandrel, synchromesh gear, retainer, steel ball, seal ring and lasso, synchromesh gear and mandrel are sleeved on mandrel by interference fit, very high to the requirement of magnitude of interference when being press-fitted, magnitude of interference is little, easily causes synchromesh gear to come off from mandrel; Magnitude of interference is large, easily causes mandrel bending deflection when being press-fitted.
Summary of the invention
The object of the invention is the above-mentioned deficiency overcoming prior art, and a kind of friction twister bearing not needing to fill synchromesh gear is provided.
Technological scheme of the present invention is: a kind of friction twister bearing, and it comprises outer ring and mandrel, and inside, outer ring is provided with outer raceway groove, and its two ends are provided with seal groove; Mandrel is provided with interior raceway groove; To be set on mandrel cover and to have retainer, the outer raceway groove of raceway groove and outer ring in some steel balls, steel ball and mandrel is housed in the pocket hole of retainer matches between mandrel and outer ring, outer ring seal groove is equipped with seal ring and diaphragm seal, on mandrel, the outer end cover of seal ring has lasso, lasso exterior edge face far from outer ring in the same way end face distance be H, the mandrel of diaphragm seal outer end is provided with synchronous gear.
The further technological scheme of the present invention is: the number of teeth of described synchronous gear is 20 teeth.
The further technological scheme of the present invention is: described mandrel has opening slot near the end end of synchronous gear.
The further technological scheme of the present invention is: described distance H is 13mm.
The beneficial effect of hinge structure of the present invention is: directly on mandrel, be provided with synchronous gear owing to have employed, and solves the problem that existing synchromesh gear and mandrel are press-fitted magnitude of interference, both there will not be magnitude of interference little, and easily caused synchromesh gear to come off from mandrel; Also there will not be magnitude of interference large, easily causing mandrel bending deflection when being press-fitted; The length of synchromesh gear part and shortening mandrel can also be reduced simultaneously, save production cost.

Reference character: 1, outer ring, 2, mandrel, 3, retainer, 4, steel ball, 5, diaphragm seal, 6, seal ring, 7, lasso, 8, opening slot, 9, synchronous gear.
Embodiment
Below in conjunction with figure and embodiment, detailed construction of the present invention is further described.
As shown in Figure 1 and Figure 2, a kind of friction twister bearing of the present invention, it comprises outer ring 1 and mandrel 2, and inside, outer ring 1 is provided with outer raceway groove, and its two ends are provided with seal groove; Mandrel 2 is provided with interior raceway groove; Between mandrel 2 and outer ring 1 and be set in mandrel 2 overlaps have retainer 3, in the pocket hole of retainer 3, some steel balls 4 be housed, steel ball 4 matches with the outer raceway groove of raceway groove in mandrel 2 and outer ring 1, outer ring 1 seal groove is equipped with seal ring 6 and diaphragm seal 5, on mandrel 2, the outer end cover of seal ring 6 has lasso 7, lasso 7 exterior edge face far from outer ring 1 in the same way end face distance be H, the mandrel 2 of diaphragm seal 5 outer end is provided with synchronous gear 9.
The number of teeth of described synchronous gear 9 is 20 teeth.
Described mandrel 2 has opening slot 8 near the end of synchronous gear 9 one end.
Described distance H is 13mm.
Working principle of the present invention and using method are: during the present invention's one friction twister bearing working, synchronous cog belt being sleeved on the synchronous gear 9 of corresponding friction twister bearing core shaft 2, driving whole friction twister bearing to run up by driving synchronizing jugged tape travel.The present invention is directly provided with synchronous gear owing to have employed on mandrel, solves the problem that existing synchromesh gear and mandrel are press-fitted magnitude of interference, both there will not be magnitude of interference little, and easily caused synchromesh gear to come off from mandrel; Also there will not be magnitude of interference large, easily causing mandrel bending deflection when being press-fitted; The length of synchromesh gear part and shortening mandrel can also be reduced simultaneously, save production cost.
More than show and describe basic principle of the present invention and major character; the technician of the industry should understand; above-described embodiment does not limit the present invention in any form, the technological scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection scope of the present invention.
