Abstract

This invention is dealing with a unilateral cage closed to the bearing with high revolutions which consists of the shell (2) and of the axle (5) with rotary trajectories and guiding planes, and of the rolling bodies (6) located in the cage (1), where a conic slope is created, while this slope is located on the internal guiding plane (4) of the shell (2) and / or on the external plane (3) of the cage (1) with the angle (alpha) greater than zero, however less or equal 5 degrees, while th e internal guiding hole (7) closed to the cage (1) is of a cylindrical shape.

Description

Oblasť technikyTechnical field

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, in particular intended to accommodate a spinning rotor of a textile machine with a speed exceeding 8.10 4 min. 1 .

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. Na takéto ložisko je možné použiť len jednostranné klietky vedené buď v puzdre alebo na hriadeli. Pri vysokých otáčkach dochádza k opotrebovaniu 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. Only one-sided cages guided either in the housing or on the shaft can be used for such a bearing. At high revolutions, the cages are worn 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.

Priemyselná využiteľnosťIndustrial usability

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

Podstata vynálezuSUMMARY OF THE INVENTION

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. Podstatou vynálezu je, že na vnútornej vodiacej ploche puzdra a/alebo na vonkajšej vodiacej ploche klietky je vytvorený od valivých teliesok kužeľový sklon pod uhlom a väčším ako 0 a menším najviac sa rovnajúcim 5 uhlovým stupňom, pričom vnútorný vodiaci otvor klietky má valcový tvar.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. It is an object of the invention that on the inner guide surface of the housing and / or on the outer guide surface of the cage, a conical slope is formed from the rolling elements at an angle greater than 0 and less than 5 degrees.

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 na valivé telieska. 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 to the cage in the axial direction, namely in the direction of the closed side on the rolling elements. Thus, the one-sided cage partially acquires the properties of a double-sided cage, thereby ensuring its reliability at high speed.
