Description

A kind of axial movement of bearing

Technical field

This utility model belongs to field of bearings, a kind of axial movement of bearing.

Background technology

Bearing be plant equipment for the indispensable parts of transmission, its effect mainly support rotating parts, it is achieved turn Dynamic component being rotatably assorted relative to fixed component, namely fixed rotating shaft makes it can only realize rotating, and control its axially and Movement radially.

Most bearing, when connecting, is that outer ring is connected with external part, and inner ring is connected with inner part, and inner part is with outside The most only it is rotation relation between part, but in some cases, not only needs being rotationally connected between inner part and external part, Also need to occur in the axial direction of bearing between inner part with external part relative slip, as connected by bearing between a pair sleeve pipe Connect, need not only to relatively rotate between two sleeve pipes, in addition it is also necessary to can occur relatively to slide (the most axially opposite slip), but If only simply sliding, frequent friction not only can wear sleeve, and the relative frictional force of sliding friction is bigger, to two Relatively sliding between individual sleeve pipe produces obstruction；But also bigger heat can be produced, if things go on like this, either bearing still overlaps Pipe all can reduction of service life, therefore need the bearing that can solve this situation badly.

Utility model content

For the deficiencies in the prior art, this utility model provides a kind of by arranging a circle ball in the outer ring of bearing, Make occur between the outer ring of bearing and external parts relative movement, and movement between the two is rolling friction, makes both Between movement be more prone to and reduce abrasion, save the axial movement of bearing of the energy.

For achieving the above object, this utility model provides following technical scheme: a kind of axial movement of bearing, including inner ring And outer ring, it is provided with retainer between inner ring and outer ring, retainer is provided with interior ball, described outer ring is provided with several The outer ball that energy is freely rotatable, described outer ball, along the evenly distributed setting of circumferencial direction of outer ring, described outer ring is arranged with outer Ball is corresponding and is used for accommodating the spherical groove of outer ball.

Further, described outer ring is provided with several circumferential band being fixed on outer ring by outer ball, and circumferential band With spherical groove one_to_one corresponding.

Further, removably connect between described circumferential band and outer ring.

Further, described circumferential band is tungsten carbide with the material of outer ball.

Compared with prior art, the beneficial effects of the utility model are:

1, by the setting of outer ball, outside making the sliding friction between external parts and the outer ring of bearing of bearing be converted into The rolling friction of ball, so can effectively reduce the abrasion of outer ring and external parts, and the slip reducing external relay part is produced Raw obstruction, reduces frictional heat, extends the service life of bearing and external parts, reduces the waste of resource, saves the energy.

2, by spherical groove and the setting of circumferential band, can effectively control that outer ball is upper in outer ring to be put, make each outer rolling Pearl is individually fixed on the fixed position on outer ring, and makes the outer ball can be freely rotatable in spherical groove, so that ball supports Connect external part, so that the sliding friction between external part and outer ring is converted into the rolling friction of outer ball.

Detailed description of the invention

Referring to figs. 1 through Fig. 5, the embodiment of this utility model axial movement of bearing is described further.

A kind of axial movement of bearing, including inner ring 2 and outer ring 1, is provided with retainer 3 between inner ring 2 and outer ring 1, keep Being provided with interior ball 4 on frame 3, described outer ring 1 is provided with several outer balls 5 that can be freely rotatable, described outer ball 5 is along outward The evenly distributed setting of circumferencial direction of circle 1, described outer ring 1 arranges ball that is corresponding with outer ball 5 and that be used for accommodating outer ball 5 Shape groove 8.Preferably, outer ball 5 is arranged on the face (the excircle side of outer ring 1) that outer ring 1 is connected with external parts, preferably , the bottom surface of outer ring 1 is also equipped with outer ball 5, it is preferred that outer ball 5 is provided with many on outer ring 1 along axis direction Row, so that portion inside part and external parts reach stable effect when relative movement.

This utility model bearing in use, is arranged between external parts and portion inside part, such as the situation of a pair sleeve pipe, Being provided with bearing between inner tube and outer tube, the upper outer ball 5 arranged in 1, the outer ring of bearing abuts outer tube wall, and inner tube is rotating While, bearing is connected as a single entity with inner tube, rotates within the outer tube and moves axially, and the interior ball 4 of bearing is in the outer ring 1 of bearing And rolling between inner ring 2, the outer ball 5 of bearing rolls between outer ring 1 and outer tube wall, reduce between outer ring 1 and outer tube Friction, reduces the obstruction slided between the two, makes the slip between outer tube and inner tube be more prone to, and reduce abrasion, fall Low frictional heat, extends the service life of inner tube and outer tube, reduces the waste of resource wave, saves the energy.

The present embodiment is preferred, described outer ring 1 is provided with several outer ball 5 is fixed on the circumferential band on outer ring 1 6, and circumferential band 6 and spherical groove 8 one_to_one corresponding.The present embodiment is preferred, removably connects between described circumferential band 6 and outer ring 1.

The present embodiment is preferred, and the groove shapes of spherical groove 8 is hemisphere, and the face that circumferential band 6 is connected with outer ring 1 is ball arc Curved surface, two spheres just make ball card inside and make ball to roll, and circumferential band 6 and corresponding with spherical hoop outside Being provided with screwed hole on circle 1, both connect fixing by bolt 7.

The present embodiment is preferred, and described circumferential band 6 is tungsten carbide with the material of outer ball 5；Increase circumferential band 6 and outer rolling The hardness of pearl 5 and abrasion resistance, extend both service life.

The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to Above-described embodiment, all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.Should refer to Go out, for those skilled in the art, without departing from the some improvement under this utility model principle premise and Retouching, these improvements and modifications also should be regarded as protection domain of the present utility model.
