[0002] The opening roller bearings used on rotor spinning machines are mainly composed of outer rings, mandrels, cages, rolling elements (rollers or balls), dust-proof rings, etc.; because there is no positioning structure on the outer rings of this type of bearings , when the bearing is pressed into the roller body and put into the rotor seat, when the bearing is running at high speed, the end surface of the roller body and the rotor seat are likely to rub against each other, resulting in rapid wear of the bearing, decreased precision and unstable rotation, resulting in overheating of the surface Burn out, reduce service life

Embodiment Construction
[0014] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.
[0015] Such as figure 1 with figure 2 As shown, the present invention includes an outer ring 6, the inner two ends of the outer ring 6 have a cage 7, the cage 7 is matched with the ball 8, and the ball 8 is located in the annular groove on the mandrel 1; the two ends of the outer ring 6 The inner circle is equipped with a dust-proof ring 2, and the outer ring 6 has an annular groove, and the annular groove has a refueling hole 5, and the annular groove is set inside the refueling ring 4; one end of the outer ring 6 is outside The positioning ring 3 is installed on the circle, the outer diameter of the positioning ring 3 is Φ30~Φ40mm, and the width is 0.5~10mm. After the bearing is pressed into the roller body 11, the end surface of the positioning ring 3 is higher than the end surface of the roller body 11. It is 0.01~5mm. After the bea...

Abstract
The invention relates to a novel combing roller bearing which comprises an outer ring, wherein cages are equipped at the two ends of the interior of the outer ring and matched with balls; the balls are located in a ring-shaped concave groove formed in a core shaft; dustproof rings are mounted at the internal circumferences at the two ends of the outer ring; the outer ring is provided with ring-shaped grooves; the ring-shaped grooves are provided with oil feeding holes; oil feeding rings are sleeved with the ring-shaped grooves; a positioning ring is mounted at the external circumference at one end of the outer ring; after the bearing is pressed into a roller body, the end surface of the positioning ring is higher than that of the roller body. The novel combing roller bearing has a simple structure, and is high in running precision, less in abrasion and long in service life.
Description
technical field [0001] The invention relates to the technical field of bearings, in particular to a carding roller bearing used on a rotor spinning machine. Background technique [0002] The opening roller bearings used on rotor spinning machines are mainly composed of outer rings, mandrels, cages, rolling elements (rollers or balls), dust-proof rings, etc.; because there is no positioning structure on the outer rings of this type of bearings , when the bearing is pressed into the roller body and put into the rotor seat, when the bearing is running at high speed, the end surface of the roller body and the rotor seat are likely to rub against each other, resulting in rapid wear of the bearing, decreased precision and unstable rotation, resulting in overheating of the surface Burning failure, reducing service life. Contents of the invention [0003] Aiming at the above-mentioned shortcomings in the prior art, the applicant provides a new type of carding roller bearing, whic...
