Most of preoriented yarns carry out false twisting using frictional disk or apron currently on the market, its main feature is that it is high-efficient, but rub
It wipes disk or apron more or less will cause damage to yarn, influence the quality of silk.Therefore this kind of equipment mainly for the production of it is low at
Originally, popular garment material or other textiles.The bearing that friction-disc scroll tube uses is known as scroll tube bearing, is divided into
Active bearings and driven bearing.In addition false twisting is carried out using rotator type scroll tube there are also a kind of, although the efficiency ratio of this equipment
It is lower, at high cost, but can guarantee the high-quality of silk, it is typically used for manufacture top grade, high added value garment material, this vacation
The bearing that twister uses is exactly scroll tube speedup wheel bearing.One is entirety for the structure of common speedup wheel bearing currently on the market
Formula double-groove bearing, another kind are halfbody formula double-groove bearings.
Summary of the invention
The utility model, provides a kind of high speed speedup wheel component of the use with pre-pressing structure, which has bearing revolving speed
The characteristics of high, with small vibration, low in energy consumption, low noise, increases pre- since position have passed through special structure design between two bearings
The clamp force structural constraint end-play of bearing, can the very big revolving speed that must improve bearing so that scroll tube is with small vibration, operating is flat
Surely.
According to technical solution provided by the utility model: a kind of high speed multiplying wheel parts of bearings with pre-pressing structure, it is special
Sign is: including bearing spindles, dustproof cover, retainer, bearing outer ring, Kong Yongyuan R shape retaining ring, preloading spring, cartridge housing, steel ball,
Dustband；
Biserial channel is machined on the bearing spindles, the bearing outer ring, steel ball and retainer constitute one group of bearing rolling
Kinetoplast engaging member, each column channel constitute the bearing roller of upper and lower sides with one group of bearing roller engaging member respectively；Two sides
Bearing roller collectively constitutes the double channel rolling bearing of speedup wheel bearing；
Dustproof cover is packed into the bearing housing hole of the bearing outer ring of side, wherein being upside equipped with dustproof cover side；
Bearing roller engaging member is placed in cartridge housing, is milled flat place close to the cartridge housing shaft shoulder inside cartridge housing and is provided with retaining ring
Slot, the load hole circle R shape retaining ring at circlip groove, circle R shape retaining ring blocks the bearing outer ring of upside, in the bearing of retaining ring and downside
Preloading spring is additionally provided between outer ring；
Dustproof cover side orifice end is thin-walled, and orifice end crimping together with the round mouth end of dustproof cover in side packs tightly；
The lower end of cartridge housing is provided with dust-proof ring recess, is packed into dustband.
Further improvement of these options, high speed multiplying wheel parts of bearings length 95mm~102mm with pre-pressing structure,
Overall length 135mm~142mm after tensioning wheel is installed lower part.
Further improvement of these options, being closer to dustproof cover side outside cartridge housing has the shaft shoulder, and two side milling of the shaft shoulder is flat,
There are partial threads outside shaft shoulder lower bearing shell, convenient for the installation and locking of parts of bearings, cartridge housing dress dustband side is provided with filling
Hole.
The utility model has the technical effect that the utility model product structure advantages of simple, and product has revolving speed height, vibration
It moves that small, the service life is long, low-power consumption, low noise and other advantages, the maximum speed of product especially greatly improved, bearing maximum speed is reachable
90,000~100,000 rev/min, significantly larger than common 20,000~30,000 rev/min of multiplying wheel highest of revolving speed.Improve vacation
The efficiency of twister keeps the wire vent effect of elasticizer more preferable.
