Abstract

The utility model relates to a roller-type bearing used for a spinning machine which replaces a traditional ball bearing by a roller bearing, comprising a roller shaft, a rubber tube, a bearing shell, a roller bearing, a bearing holder, a locating ring, and a seal cap. The utility model which solves the problems that the traditional ball bearing type roller bearing can be used only once and can not be repaired has the advantages of long service life, and good elastic surface, etc.; the quality of a spinning yarn is raised effectively.

Description

Roller-type bearing

The utility model is a kind of roller bearing that is used for the drawing-off sliver, belongs to field of textile machinery.

Widely used roller bearing on spinning machine is to be with two row's balls respectively at roller axle two, is with a bearing shell in the two row's ball outsides of each, overlaps a rubber tube then on the bearing shell again.The middle part of roller axle is fixed on the reel cage of spinning machine, the sliver that is distributed in the rubber tube surface is the yarn count of drafted one-tenth even thickness after by the roller bearing, but because the ball bearing that uses, contact-making surface is little, easy to wear, life-span lacks and can't repair, can only disposablely use, outside rubber tube under constant situation, the cartridge housing external diameter is reduced, can only do the wall thickness of rubber tube thinner, cause existing roller bearing ubiquity poor flexibility, influence the quality of yarn count.

The purpose of this utility model is in order to overcome above-mentioned weak point of the prior art, a kind of good springiness to be provided, can effectively improve the yarn count quality, and long service life also can be changed the roller roller bearing of wear-out part.

Technical measures of the present utility model are to replace ball bearing with roller bearing, because roller bearing is more much bigger than the contact-making surface of ball bearing, so can use the less roller bearing of diameter, under the constant situation of total external diameter, can increase the thickness of rubber tube tube wall, improve the elastic performance of roller bearing, can effectively improve the yarn count quality, simultaneously, when roller bearing after wearing and tearing, the bigger roller bearing of available diameter is changed, and repairs easily.Its structure and installation site are: symmetry is equipped with rubber tube, cartridge housing, roller bearing, bearing cage, centring ring and seal cover at two of a roller axle, wherein bearing shell is on the roller axle, between cartridge housing and roller axle, roller bearing and bearing cage are housed, centring ring is equipped with in both ends or one end at roller bearing, seal cover covers the outer end at cartridge housing, and rubber tube tightly is enclosed within on the cartridge housing.The roller of roller roller bearing can be by two row or single compositions, the locate modes of two row's roller roller bearings are in the cartridge housing of relative position between two row's roller bearings an inwardly outstanding protruding circle to be arranged, and on the roller axle that effluxes the roller bearing outside centring ring are housed; The locate mode of single roller roller bearing is at the two ends of roller bearing a centring ring to be housed respectively, and a turn is housed in the cartridge housing of outside centring ring, and the roller axle is at the diameter that the roller bearing position is installed choice refreshments slightly.

Accompanying drawing 1 is two row's roller roller bearing arrangement schematic diagrames;

Accompanying drawing 2 is single roller roller bearing arrangement schematic diagrames.

Be further described as follows in conjunction with the accompanying drawings:

Referring to accompanying drawing 1, earlier interior row's roller bearing 6 is contained on the roller axle 8 together with inner bearing retainer 5, arrange on the roller bearing 6 in again cartridge housing 7 being enclosed within, to efflux roller bearing 3 and outer bearing retainer 4 then is enclosed between cartridge housing 7 and the roller axle 8, do not hold dress centring ring 2 at the roller axle again, make roller bearing and cartridge housing not produce between centers and move, do not hold at cartridge housing at last and load onto seal cover 1 and rubber sleeve is got final product on cartridge housing.Add man-hour, the roller axle is big with the diameter of the inboard relevant position of interior row's roller bearing, the cartridge housing middle part and two row's roller bearings between an inwardly outstanding protruding circle is arranged on the corresponding position.

Referring to accompanying drawing 2, elder generation is enclosed within interior centring ring 17 in the cartridge housing 16 and installs to the middle part of roller axle 15, then roller bearing 14 and bearing cage 18 are contained on the roller axle 15, again cartridge housing 16 is got back to position the figure from roller axle middle part, refill outside fix circle 13 and turn 12, at last, do not hold at cartridge housing and load onto seal cover 14 and rubber sleeve is got final product on cartridge housing.Add man-hour, the roller axle is thin slightly at the diameter that the roller bearing position is installed.

When abrasion is serious, can take off roller bearing by the reverse order of above-mentioned erection sequence, change the bigger roller bearing of diameter and can reuse.

The ball-type roller bearing that the utility model uses tradition changes roller roller bearing into, cartridge housing is outer through reducing 20%, the rubber tube wall thickness can increase by 40%, increased the surface elasticity of roller bearing, improved the quality of spinning yarn count, also have long service life simultaneously and advantage such as can repair, can replace the ball-type roller bearing of traditional use and be widely used.

Claims

1, a kind of roller roller bearing that is used on the spinning machine is in two of a roller axle symmetry rubber tube, cartridge housing, bearing, bearing cage, centring ring and seal cover to be housed, and it is characterized in that bearing is a roller bearing; Its installation site is: bearing shell is equipped with roller bearing and bearing cage between cartridge housing and roller axle on the roller axle, in the both ends or one end of roller bearing centring ring is housed, and seal cover covers the outer end at cartridge housing, and rubber tube tightly is enclosed within on the cartridge housing.

2, roller roller bearing as claimed in claim 1 is characterized in that roller bearing is made up of two row's roller bearings, in the cartridge housing of relative position a protruding circle of inwardly giving prominence to is arranged between two row's roller bearings.

3, roller roller bearing as claimed in claim 1 is characterized in that roller bearing is made up of single roller bearing, and the roller axle is thin slightly at the diameter that the roller bearing position is installed.
