Abstract

The utility model relates to a ceramic sleeve bearing for a conveyer, which belongs to the field of bearings and comprises a bearing outer sleeve and a bearing inner sleeve, wherein the bearing outer sleeve is sheathed on the bearing inner sleeve; the right end of the bearing inner sleeve is provided with a step for preventing the bearing outer sleeve from slipping off the bearing inner sleeve; the left end of the bearing inner sleeve is provided with a check ring; the bearing outer sleeve is made of special type wear-resistant ceramics; the bearing inner sleeve is made of alloys; a plurality of micropores are arranged on the fitting surface of the bearing inner sleeve and the bearing outer sleeve; and the special type wear-resistant ceramics are cast in the micropores. The ceramic sleeve bearing for the conveyer solves the problems that the bearing in the prior art cannot integrate the abrasive resistance and the toughness and has short service life. The utility model has the advantages of high hardness, good abrasive resistance, toughness and shock resistance and long service life and is not easy to break.

Description

Conveyer ceramic jacket bearing

Technical field

The utility model relates to a kind of bearing, particularly a kind of plain bearing that is used on the conveyer.

Background technology

At present, the conveyer of prior art mainly contains alloy bearing and ceramic bearing with bearing, traditional alloy bearing, in other words, the bearing that to be bearing outside and bearing inner sleeve make by alloy material is because its hardness is low, defective such as wear no resistance has been not suitable for being applied in and has worked long hours in the abominable occasion of operating mode, and has the hardness height, the ceramic bearing of characteristics such as wear-resistant, in other words, it is low to be that bearing that bearing outside and bearing inner sleeve are made by the special, wear-resistant stupalith has just remedied alloy bearing hardness, the defective that wears no resistance, but because the toughness of ceramic bearing, Dent resistance is relatively poor, and is therefore impaired cracked easily.

The utility model content

The technical problems to be solved in the utility model is, a kind of not only hardness height is provided, and is wear-resistant, and toughness, Dent resistance are good, not easily broken, thus the conveyer that has prolonged service life greatly ceramic jacket bearing.

For solving the problems of the technologies described above, the utility model provides a kind of conveyer of following structure ceramic jacket bearing: comprise bearing outside and bearing inner sleeve, bearing outside is enclosed within on the bearing inner sleeve, the bearing inner sleeve right-hand member is provided with and is used to the step that prevents that bearing outside from skidding off from bearing inner sleeve, the left part of bearing inner sleeve is equipped with back-up ring, wherein, bearing outside is to be made by the special, wear-resistant pottery, bearing inner sleeve is to be made by alloy, be furnished with some apertures on the fitting surface of bearing inner sleeve and bearing outside, be cast with the special, wear-resistant pottery in the aperture.

Conveyer described in the utility model ceramic jacket bearing, wherein, aperture is along the axial and circumferential rectangular distribution of bearing inner sleeve.

Conveyer described in the utility model ceramic jacket bearing, wherein, the alloy material that is used to make bearing inner sleeve is Fine Steel Casting iron or alloy steel.

Conveyer described in the utility model ceramic jacket bearing wherein, also comprises screw, and back-up ring is the fluting back-up ring, and screw is threaded with the fluting back-up ring.

After adopting said structure, unlike the prior art, because the utility model conveyer is an alloy material with the employing of the bearing inner sleeve of ceramic jacket bearing, therefore make bearing inner sleeve have toughness and Dent resistance preferably, and, because bearing outside is to be made by the special, wear-resistant pottery, be furnished with some apertures on the fitting surface of bearing inner sleeve and bearing outside, be cast with the special, wear-resistant pottery in the aperture, therefore, when the utility model conveyer uses with the ceramic jacket bearing, in other words, when promptly relatively rotating between bearing outside and the bearing inner sleeve, at the hardness height, under the anti abrasive ceramic block supporting role, the bearing inner sleeve of being made by alloy material will be difficult for being worn, thereby make the utility model conveyer have toughness and Dent resistance preferably with the ceramic jacket bearing, when making it not easily broken, also has the hardness height, anti abrasive advantage, thereby the service life of having improved the utility model conveyer usefulness ceramic jacket bearing greatly.

The utility model conveyer with the aperture in the ceramic jacket bearing along bearing inner sleeve axially and circumferential rectangular distribution be in order between bearing outside and bearing inner sleeve, to relatively rotate, the special, wear-resistant pottery that is cast in the aperture can be more balanced to the bearing force of bearing outside, make bearing inner sleeve more be difficult for being worn, thereby further improve the service life that the utility model conveyer is used the ceramic jacket bearing.

It is when guaranteeing that bearing inner sleeve has preferably toughness and Dent resistance that the utility model conveyer adopts the purpose of Fine Steel Casting iron or alloy steel with the bearing inner sleeve in the ceramic jacket bearing, can also suitably improve the abrasion test of bearing inner sleeve, thereby further improve the service life that the utility model conveyer is used the ceramic jacket bearing.

The utility model conveyer is the fluting back-up ring with the back-up ring in the ceramic jacket bearing, and to be threaded with the fluting back-up ring with screw be for the back-up ring that guarantees to slot is in tight condition all the time, prevents that its appearance from becoming flexible.
