Abstract
The utility model relates to a ball-roller bearing, comprising an inner and an outer bearing rings and balls. The ball-roller bearing is characterized in that a pulley type roller 4 is arranged between two neighbouring balls 3, exterior contacted with the two neighbouring balls 3 and fixed on a round belt-shaped dust ring 6 which are arranged on the both sides of the utility model; the surrounding of the balls has no sliding friction, the edge of the roller is not contacted with the inner and the outer bearing rings and the dust rings of the both sides; the direction of rotation of the roller is opposite to the direction of rotation of the balls, and the friction drag is small, which increases the mechanical efficiency and reduces the energy consumption. The dust ring is integrated with the roller to be point-contacted by the balls and to be positioned crossly, and the dust ring and the roller are restricted by a round of the balls to be concentric with the inner and the outer bearing rings and synchronous with the rotation of the balls, which effectively prevents the invasion of the dust, reduces the abrasion and extends the service life.
Description
The utility model relates to a kind of rolling bearing.
For reducing the bearing self friction, multiple novel bearing has appearred in the prior art, as " the double roller bearing " of Chinese patent bulletin (CN2052840U), a swivel becket that can rotate is set between two row rollers, two row rollers intersect on the convex-concave circular arc of swivel becket, increased the bearing load ability, but still have sliding friction on the surface of contact between two row rollers, mechanical efficiency is low.And adsorb dust easily, and having increased rolling resistance, working life is short.
The purpose of this utility model is in order to overcome above-mentioned deficiency, and a kind of to reduce sliding friction, mechanical efficiency height, energy consumption little and provide, the ball roller bearing of long service life.
Technical solution of the present utility model is such: the ball roller bearing comprises interior Cheng Quan, holds circle, ball outward, it is characterized in that between every adjacent two balls, a pulley roller being housed, groove is mutually circumscribed with two adjacent balls between the waist of pulley roller, the pulley roller is fixed on by pivot pin on the circular band shaped dust ring of both sides by the axle center circular hole, and the dustproof contact of punctuating is enclosed on the ball one.
Accompanying drawing 1 is the utility model structural drawing;
Accompanying drawing 2 is the A--A sectional view;
Accompanying drawing 3 is the B--B sectional view.
Now illustrated embodiment is made detailed description to the utility model in conjunction with the accompanying drawings.
Interior hold circle 1 and outside hold circle and ball 3 be housed between 2, between every adjacent two balls 3, a pulley roller 4 is housed, groove is mutually circumscribed with two adjacent balls 3 between the waist of pulley roller 4, pulley roller 4 is fixed on by pivot pin 5 on the circular band shaped dust ring 6 of both sides by the axle center circular hole, and 6 contacts of dust ring are on a circle ball 3.
The utility model is owing to adopt above design, the spill ball is walked the mutually circumscribed and located lateral of groove and adjacent two balls 3 between the waist of pulley roller 4, fricton-tight friction around the ball 3, the edge of pulley roller 4 does not contact the inside and outside circle (1,2) that holds, do not contact the dust ring 6 of both sides yet, its rotating direction is opposite with ball 3 rotating directions, surface friction drag is little, though pulley roller 4 has certain friction with pivot pin 5, but the arm of force (radius of roller) is doubly a lot of greater than weighing arm (pivot pin radius), the contact of approximate point, thus energy consumption reduced, improved mechanical efficiency; Because circular band shaped dust ring 6 and pulley roller 4 disjunctors, dust ring 6 is contacted and located lateral by 3 on ball, the location of other directions is subjected to a circle ball 3 restrictions, and it is concentric with the inside and outside circle (1,2) that holds, with ball 3 rotational synchronization, prevent the dust intrusion effectively, reduced abrasion, prolonged working life.
