Abstract
The utility model provides a shield pump bearing comprising a bearing sleeve, wherein a gap is formed at the outer side of the bearing sleeve and the inner hole wall of the bearing sleeve is provided with spiral grooves. The shield pump bearing is characterized in that vertical inner hole grooves are distributed on the inner hole wall of the bearing sleeve; and parts, corresponding to the inner hole grooves, on the top of the bearing sleeve are provided with opening grooves. The shield pump bearing is additionally provided with the inner hole grooves and the opening grooves on the basis of the original shield pump bearing, thus the bearing has less possibility of generating heat in movement and consequently the service life of the bearing is prolonged.
Description
Technical field
The utility model relates to the oilless bearing in a kind of canned motorpump.
Background technique
The impeller of canned motorpump and the rotor of motor are fixed on the same axis, utilize housing that the rotor and the stator of motor are separated, and rotor turns round in the medium that is transferred, and its power passes to rotor through stator field.Shield pump bearing is the vitals in the canned motorpump.Existing shield pump bearing generally includes axle sleeve, and the axle sleeve outside forms breach, on the inner hole wall of axle sleeve, has spiral chute.The shield pump bearing shortcoming of this kind structure is easy heating, causes bearing wear, thereby shortens the life-span of bearing.
Summary of the invention
Thereby the purpose of the utility model provides the bearing that is used for canned motorpump that a kind of difficult heating increases the service life.
In order to achieve the above object; The technological scheme of the utility model has provided a kind of shield pump bearing; Comprise axle sleeve, be formed with breach, on the inner hole wall of axle sleeve, have spiral chute in the outside of axle sleeve; It is characterized in that: on the inner hole wall of axle sleeve, be distributed with vertical interior hole slot, the position at the top of axle sleeve corresponding to interior hole slot has opening slot.
The utility model has increased interior hole slot and opening slot on the basis of original shield pump bearing, thereby makes bearing in movement process, be difficult for heating, thereby has prolonged the working life of bearing.
Description of drawings
The side sectional view of a kind of shield pump bearing that Fig. 1 provides for the utility model;
The plan view of a kind of shield pump bearing that Fig. 2 provides for the utility model.
Embodiment
For making the utility model more obviously understandable, now with a preferred embodiment, and conjunction with figs. elaborates as follows.
Like Fig. 1 and shown in Figure 2; A kind of shield pump bearing that the utility model provides; Comprise axle sleeve 1, be formed with breach 5, on the inner hole wall of axle sleeve 1, have spiral chute 3 in the outside of axle sleeve 1; On the inner hole wall of axle sleeve 1, be distributed with vertical interior hole slot 4, the position at the top of axle sleeve 1 corresponding to interior hole slot 4 has opening slot 2.
In the present embodiment, axle sleeve 1 adopts carbofrax material to make, and original shield pump bearing then is to adopt graphite material.Graphite material causes the shield pump bearing easy abrasion, can not guarantee coaxality.And after adopting carbofrax material to make, axle sleeve 1 is not easy to wear, can must guarantee coaxality better.
Claims (1)
1. shield pump bearing; Comprise axle sleeve (1); Be formed with breach (5) in the outside of axle sleeve (1); On the inner hole wall of axle sleeve (1), have spiral chute (3), it is characterized in that: on the inner hole wall of axle sleeve (1), be distributed with vertical interior hole slot (4), the position at the top of axle sleeve (1) corresponding to interior hole slot (4) has opening slot (2).
