Abstract

The utility model discloses a bearing which can preventing a fabric guide roll from abrading and can prolong the service span of the fabric guide roll. The bearing comprises a ball case provided with a shaft hole, wherein the outer surface of the ball case is a ball shape, a bearing is arranged outside the ball sleeve, the shaft sleeve comprises two semi shaft sleeves which are closed through an extension spring, the ball-shaped outer surface of the ball sleeve and the ball-shaped inner surface of the shaft sleeve are in fit clearance. The bearing is suitable for fabric guide roll mounting places in the printing and dyeing industry.

Description

Bearing

Technical field

The utility model relates to a kind of bearing, refers more particularly to a kind of bearing that is used on the dyeing apparatus fabric guide roll.

Background technique

Aspect printing and dyeing, bearing is at present: square axle sleeve, square axle sleeve are fixedly mounted on the wall panel or supporting frame in the dyeing apparatus usually, are provided with axis hole in the inside of axle sleeve, and the axis hole of the spindle nose of fabric guide roll being put into axle sleeve gets final product.Because fabric guide roll is very long, add in the process of rotation friction with axle sleeve, and there is a large amount of solid matters to advance in the gap of people's spindle nose and axle sleeve, make that the edge abrasion of axis hole is very fast, and the spindle nose of fabric guide roll also is subjected to wearing and tearing in various degree, after the spindle nose that is in the fabric guide roll two ends is subjected in various degree wearing and tearing, fabric guide roll will tilt, can make the cloth sideslip on the fabric guide roll wrinkling, so just need often to change axle sleeve or whole fabric guide roll, because fabric guide roll costs an arm and a leg, this has just improved cost of production.

The model utility content

The purpose of this utility model is to provide a kind of and avoids the fabric guide roll wearing and tearing and can prolong the fabric guide roll bearing in working life.

For achieving the above object, the technical solution adopted in the utility model is: a kind of bearing, comprise ball cover with axis hole, the outer surface of described ball cover is spherical, outer installment at ball cover has axle sleeve, axle sleeve is closed up by extension spring by two half-axile sleeves and forms the spherical inside surface Spielpassung of the spherical outer surface of ball cover and axle sleeve;

Be respectively arranged with boss and groove on the described half-axile sleeve, boss and groove Spielpassung;

Be respectively arranged with the extension spring groove on the described half-axile sleeve;

The shaft hole inner wall of described ball cover is provided with one section keyway with exterior.

The utility model has the advantages that: after adopting ball cover, the wearing and tearing of fabric guide roll have been transferred to the wearing and tearing of ball cover.Because the outer surface of ball cover is spherical, so can also play the aligning effect to fabric guide roll.After increasing ball cover, the spindle nose of fabric guide roll almost without any wearing and tearing, prolonged the working life of fabric guide roll in the dyeing apparatus, greatly reduce cost of production.

Wherein: 1, axis hole, 2, ball cover, 3, go up half-axile sleeve, 4, half-axile sleeve down, 5, Zola's spring, 6, right extension spring, 7, go up the extension spring groove, 8, the tension spring groove, 9, convex platform, 10, upper groove, 11, lower convex platform, 12, low groove, 13, keyway.

Embodiment

Below in conjunction with the drawings and specific embodiments technological scheme described in the utility model and working principle thereof and advantage are further described.

As Fig. 1, Fig. 2 and shown in Figure 3, a kind of bearing, comprise ball cover 2 with axis hole 1, the outer surface of ball cover 2 is spherical, outer installment at ball cover 2 has axle sleeve, axle sleeve is made up of last half-axile sleeve 3 and following half-axile sleeve 4, in the present embodiment, easy for installation for bearing, outer surface at last half-axile sleeve 3 and following half-axile sleeve 4 is respectively arranged with extension spring groove 7 and tension spring groove 8, last half-axile sleeve 3 closes up with right extension spring 6 by Zola's spring 5 with following half-axile sleeve 4 is in the same place, the extension spring that is positioned at the outside of half-axile sleeve 3 and following half-axile sleeve 4 lays respectively at extension spring groove 7 and tension spring groove 8, the spherical inside surface Spielpassung of the outer surface of ball cover 2 and axle sleeve, in the present embodiment, last half-axile sleeve 3 is provided with convex platform 9 and upper groove 10, following half-axile sleeve 4 is provided with lower convex platform 11 and low groove 12, convex platform 9 and low groove 12 Spielpassung, upper groove 10 and lower convex platform 11 Spielpassung, like this, when making can with on the size of half-

axile sleeve

3 and 4 making of following half-axile sleeve all identical with profile, be convenient to produce in batches, in the process of actual fabrication, also two boss can be set on last half-axile sleeve 3, two grooves are set on the following half-axile sleeve 4, groove on boss on the last half-axile sleeve 3 and the following half-axile sleeve 4 is Spielpassung respectively, the cooperation of boss and groove makes that going up half-axile sleeve 3 can not produce than large deviation in the axial direction with following half-axile sleeve 4, and can prevent that impurity such as extraneous dust from entering on the surface of contact of ball cover 2 and axle sleeve, effectively prolongs the working life of ball cover 2 and axle sleeve.Axis hole 1 inwall of ball cover 2 is provided with one section keyway 13 with exterior.

Working principle of the present utility model is: the spindle nose at fabric guide roll two ends is put into the axis hole 1 of ball cover 2 respectively, pin on the fabric guide roll is in the keyway 13 gets final product, do not draw among the figure.During work, axle sleeve is fixedly mounted on the wall panel or supporting frame in the dyeing apparatus.When fabric guide roll rotates, pin drives ball cover 2 and rotates in axle sleeve, this has just transferred to wearing and tearing between ball cover 2 and the axle sleeve to the suffered wearing and tearing of original fabric guide roll fully, and at Zola's spring 7, under the effect of right extension spring 8, remain between ball cover 2 and the axle sleeve and closely cooperate, the life-span of fabric guide roll is prolonged, as need maintenance and replacing, as long as change ball cover 2, last half-axile sleeve 3 and following half-axile sleeve 4, very convenient, and reduced cost of production, spherical simultaneously ball cover 2 has the effect of aligning, make the two ends of fabric guide roll be horizontal all the time, avoided fabric guide roll to take place because of inclination makes cloth sideslip or wrinkling situation.
