Abstract
The invention discloses a main shaft bearing of a circular knitting machine, comprising an outer ring (1), an inner ring (2) and a rolling body (3). The rolling body (3) is arranged between races of the inner ring (s) and the outer ring (1), two sides of the rolling body (3) are further provided with retainers (4), the inner ring (2) comprises symmetric two halves which are respectively provided with a half circle of race (6), the outer ring (1) is provided with two races (5), the half circle of races (6) are correspondingly matched with the races (5) of the outer ring (2) for the rolling of the rolling body (3). The structure of the bearing effectively enhances the axial load-bearing capability of the bearing and can bear a given amount of capsizing moment so as to prolong the service life of the bearing.
Description
Technical field
The present invention relates to the circular knitting machine main shaft bearing that uses in a kind of Textile Machinery, belong to technical field of rolling bearings.
Background technique
Deep groove ball bearing on the existing Textile Machinery, its structure as shown in Figure 1, it comprises that outer ring 1, inner ring 2, rolling element 3, retainer 4 form.Be respectively equipped with the raceway 5 that rolls for rolling element 3 on the inner headed face of the periphery of described inner ring 2 and outer ring 1, the raceway radius is slightly larger than the rolling element radius.
There is following defective in actual use in this bearing: at first: it mainly bears radial load and a certain amount of thrust load, when thrust load moment becomes big, the life-span of bearing will be had a strong impact on, thereby affect indirectly the life-span of frame, secondly, Bearing Installation is the setting mode, beat and have relatively high expectations, just need bearing can bear a certain amount of tilting moment this moment, and like this, general deep groove ball bearing is with regard to improper this occasion.
Summary of the invention
Technical problem to be solved by this invention provides a kind ofly can bear bigger radial and axial load, and can bear the bearing of a certain amount of tilting moment.
In order to solve above-mentioned technical problem, technological scheme of the present invention is: a kind of circular knitting machine main shaft bearing, comprise the rolling element that is provided with between outer ring, inner ring and inner ring, the outer ring raceway, the rolling element both sides also are provided with retainer, described inner ring is the two halves of symmetry, be respectively arranged with the half-turn raceway on per half, described outer ring is provided with two raceways, and described half-turn raceway cooperates for the rolling element rolling with raceway on the outer ring accordingly.
In order to reduce rolling friction, the radius of described raceway and half-turn raceway is greater than the radius of rolling element.
Bearing of the present invention is because be two raceways, and has bigger wrapping angle, similar to two single-row contact ball bearings of arranging back-to-back in design, so have rigidity preferably, and can bear bigger axial and radial load and a certain amount of tilting moment, this bearing is a separable type in addition, and is more convenient during assembling.
Bearing of the present invention has effectively strengthened the axial carrying capacity of bearing, and can bear a certain amount of tilting moment, thereby has prolonged the working life of bearing.
Description of drawings
Fig. 1 is the structural representation of the bearing body of prior art.
Fig. 2 is the structural representation of bearing of the present invention.
Embodiment
As shown in Figure 2, a kind of circular knitting machine main shaft bearing, comprise the rolling element 3 that is provided with between outer ring 1, inner ring 2 and inner ring 2, outer ring 1 raceway 5, rolling element 3 both sides also are provided with retainer 4, described inner ring 2 is the two halves of symmetry, be respectively arranged with half-turn raceway 6 on per half, described outer ring 1 is provided with two raceways 5, and described half-turn raceway 6 cooperates for rolling element 3 rollings with raceway 5 on the outer ring accordingly.
The radius of described raceway 5 and half-turn raceway 6 is in order to reduce rolling friction, to improve the life-span of rolling element 3 greater than the radius of rolling element 3.
The present invention is because two raceways of design, and has bigger wrapping angle, similar to two single-row contact ball bearings of arranging back-to-back, so have rigidity preferably, and can bear bigger axial and radial load and a certain amount of tilting moment, this bearing is a separable type in addition, and is more convenient during assembling.
The foregoing description does not limit the present invention in any way, and every employing is equal to replaces or technological scheme that the mode of equivalent transformation obtains all drops in protection scope of the present invention.
Claims (2)
1. circular knitting machine main shaft bearing, comprise the rolling element (3) that is provided with between outer ring (1), inner ring (2) and inner ring (2), outer ring (1) raceway (5), rolling element (3) both sides also are provided with retainer (4), it is characterized in that: described inner ring (2) is the two halves of symmetry, be respectively arranged with half-turn raceway (6) on per half, described outer ring (1) is provided with two raceways (5), and described half-turn raceway (6) cooperates for rolling element (3) with raceway (5) on outer ring (2) accordingly and rolls.
2. circular knitting machine main shaft bearing according to claim 1 is characterized in that: the radius of described raceway (5) and half-turn raceway (6) is greater than the radius of rolling element (3).
