Abstract

Disclosed is a unilateral cage (1) for high-speed bearing consisting of a bush (2), shaft (5) with race paths and guide surfaces, and rolling casings (6) accommodated in said cage (1). A conical inclination (alpha) to the rolling casings (6) is provided upon an inner guide surface (3) of the cage (1) and/or upon outer guide surface of the shaft (5), whilst an outer guide surface (7) of the cage (1) is of a cylindrical shape.

Description

Vynález sa týka jednostrannej klietky vysokootáčkového ložiska určeného najmä na osadenie spriadacieho rotora textilného stroja s otáčkami presahujúcimi 8.104 min.’1.BACKGROUND OF THE INVENTION The present invention relates to a one-sided cage of a high-speed bearing intended, in particular, for mounting a spinning rotor of a textile machine with a speed exceeding 8.10 4 min. 1 .

Priemyselná využiteľnosťIndustrial usability

Využitie vynálezu sa predpokladá v textilnom strojárstve.The use of the invention is contemplated in textile engineering.

Doterajší stav technikyBACKGROUND OF THE INVENTION

Na osadenie hriadeľa spriadacieho rotora textilného stroja sa používa špeciálne dvojradové ložisko zložené z puzdra, hriadeľa, v ktorých sú vytvorené obežné dráhy, ďalej z valivých teliesok, napríklad guliek, vedených klietkami a z okrajových krytov. Pri takomto ložisku je možné použiť len jednostranné klietky vedené buď v puzdre, alebo na hriadeli. Pri vysokých otáčkach dochádza k opotrebovaniu káps klietok, čo sa v ich otvorenej časti prejaví zväčšením zámkov. Tým je umožnené vysunutie klietky z venca guliek s následnou haváriou ložiska.A special double-row bearing composed of a bush, a shaft in which raceways are formed, rolling elements such as balls guided by cages and edge covers is used to fit the shaft of the spinning rotor of the textile machine. In such a bearing, only one-sided cages guided either in the housing or on the shaft can be used. At high revolutions, the cage casings wear out, which in their open part results in an increase in the locks. This allows the cage to be ejected from the rim of the bullets with the subsequent bearing accident.

Jednostranná klietka vysokootáčkového ložiska zloženého z vonkajšieho i vnútorného krúžku s obežnými dráhami a vodiacimi plochami, kde vonkajší krúžok je vytvorený puzdrom a vnútorný krúžok hriadeľom a z valivých teliesok umiestnených v klietke, vyznačujúca sa t ý m , že na vnútornej vodiacej ploche (3) klietky (1) a/alebo na vonkajšej vodiacej ploche (4) hriadeľa (5) je vytvorený kužeľový sklon pod uhlom (a) k valivým telieskam (6), pričom vonkajší vodiaci povrch (7) klietky (1) má valcový tvar.One-sided cage of high-speed bearing composed of outer and inner ring with raceways and guide surfaces, where the outer ring is formed by bushing and inner ring by shaft and rolling elements placed in the cage, characterized by the fact that on the inner guide surface (3) 1) and / or on the outer guide surface (4) of the shaft (5), a conical inclination is formed at an angle (α) to the rolling elements (6), the outer guide surface (7) of the cage (1) having a cylindrical shape. Podstata vynálezuSUMMARY OF THE INVENTION 1 výkres1 drawing Uvedené nedostatky do značnej miery odstraňuje jednostranná klietka vysokootáčkového ložiska podľa vynálezu. Takéto ložisko je zložené z vonkajšieho i vnútorného krúžku s obežnými dráhami a vodiacimi plochami, kde vonkajší krúžok je vytvorený puzdrom a vnútorný krúžok hriadeľom a z valivých teliesok umiestnených v klietke.These drawbacks are largely overcome by the one-sided high-speed bearing cage of the invention. Such a bearing is composed of an outer and an inner ring with raceways and guide surfaces, the outer ring being formed by a bushing and the inner ring by a shaft and of rolling elements housed in the cage. Podstatou vynálezu je, že na vnútornej vodiacej ploche klietky a/alebo na vonkajšej vodiacej ploche hriadeľa je vytvorený kužeľový sklon pod uhlom a k valivým telieskam, pričom vonkajší vodiaci povrch klietky má valcový tvar.It is an object of the invention that on the inner guide surface of the cage and / or on the outer guide surface of the shaft, a conical inclination is formed at an angle and towards the rolling elements, the outer guide surface of the cage having a cylindrical shape. Výhody tohto riešenia sú v tom, že v jednostrannej klietke vysokootáčkového ložiska vznikne sila pôsobiaca v osovom smere na klietku a to v smere uzatvorenej strany z hľadiska valivých teliesok. Tým jednostranná klietka čiastočne získava vlastnosti obojstranne uzatvorenej klietky, čím je zabezpečená jej spoľahlivosť pri vysokých otáčkach.The advantages of this solution are that in the one-sided cage of the high-speed bearing, a force is applied in the axial direction on the cage in the direction of the closed side in terms of rolling elements. Thus, the one-sided cage partially acquires the properties of a double-sided cage, thereby ensuring its reliability at high speed. Prehľad obrázkov na výkresochBRIEF DESCRIPTION OF THE DRAWINGS Jednostranná klietka vysokootáčkového ložiska podľa vynálezu je znázornená na pripojenom výkrese zobrazujúcom prierez ložiska, ktoré má na vnútornej vodiacej ploche klietky a na vonkajšej vodiacej ploche hriadeľa vytvorený kužeľový sklon pod uhlom a k valivým telieskam, pričom vonkajší vodiaci povrch klietky má valcový tvar.The one-sided high-speed bearing cage according to the invention is shown in the attached drawing showing a cross-section of a bearing having a cage inclined at the inner guide surface of the cage and an outer guide surface of the shaft and the outer guide surface of the cage having a cylindrical shape. Príklady uskutočnenia vynálezuDETAILED DESCRIPTION OF THE INVENTION Ložisko sa skladá z puzdra 2, hriadeľa 5, klietky 1 na valivé telieska 6, napríklad guľky a z neznázomených okrajových krytov. V zobrazenom príklade uskutočnenia je na vnútornej vodiacej ploche 3 klietky 1 a na vonkajšej vodiacej ploche 4 hriadeľa 5 vytvorený kužeľový sklon pod uhlom a k valivým telieskam 6, pričom vonkajší vodiaci povrch 7 klietky 1 má valcový tvar. Pri inom neznázornenom vyhotovení môže byť tento kužeľový sklon vytvorený len na vnútornej vodiacej ploche 3 klietky 1 alebo na vonkajšej vodiacej ploche 4 hriadeľa 5.The bearing consists of a housing 2, a shaft 5, a cage 1 for rolling elements 6, for example, balls, and an edge cover (not shown). In the illustrated embodiment, a tapered inclination at an angle and to the rolling elements 6 is formed on the inner guide surface 3 of the cage 1 and on the outer guide surface 4 of the shaft 5, the outer guide surface 7 of the cage 1 having a cylindrical shape. In another embodiment (not shown), this conical inclination can be formed only on the inner guide surface 3 of the cage 1 or on the outer guide surface 4 of the shaft 5.
