Abstract

The utility model relates to a compound bearing which is capable of bearing high rotating speed and is long in service life. The compound bearing is a compound body bearing with two layers of slideways which consists of a bearing inner body, a bearing compound body, a bearing outer body and bearing balls, wherein the compound bearing is different from the common bearing and is provided with two layers of slideways, but the bearing technology is universal. The compound bearing relates to a commonly used component in the technical field of machinery, better solves the problems of high rotating speed and long service life which are unreachable for the ordinary bearing, adopts the technology of double layers of slideways in the technical aspect, can keep the characteristics that the ordinary bearing is simple in structure, stable and reliable, and can be widely applied to some electromechanical fields which are strict for the bearing requirement.

Description

Compound bearing

Affiliated technical field

The utility model relates to the bearing that uses in a kind of mechanical field, especially it is divided into the bearing of inside and outside two-layer slideway.

Background technique

Nowadays, employed bearing all is the bearing that has only one deck slideway in mechanical field, no matter how producer improves on accuracy of manufacturing, perhaps used new material, the bearing that manufacturing is come out all can't satisfy some high-end machineries to the high rotating speed of bearing, long-life requirement, the damage of a bearing and make the thing of entire machine paralysis of common occurrence, and this compound bearing is transformed on the traditional bearing structure exactly, introduced the concept of double-deck slideway, it is simple in structure, it is durable to stablize, also realize high rotating speed, long-life requirement, reduced rotation friction.

Summary of the invention

In order to overcome the deficiency that existing bearing can't satisfy the high rotating speed of high-end machinery, long lifetime requirement, the utility model provides a kind of compound bearing, be provided with two-layer slideway, make bearing not only keep characteristics simple in structure, working stability, and satisfied the high rotating speed of high-end machinery, long-life requirement.

The technological scheme that its technical problem of the novel solution of the present invention adopts is: continue to adopt all technical requirements of plain bearing, but structurally adopted inside and outside two-layer slideway technology, the bearing housing that is equivalent to two sizes on the form is fitted together, be that little bearing endosome and big bearing ectosome are fused into the compound body that there is slideway on a two sides, utilize this compound body that interior external slideway is connected, form complete compound bearing.

The beneficial effects of the utility model are not only to keep characteristics simple in structure, working stability, and satisfied the high rotating speed of high-end machinery, long-life requirement.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is plan view of the present utility model.

Fig. 2 is sectional view of the present utility model.

1. bearing endosomes among the figure, 2. bearing compound body, 3. bearing ectosome, 4. bearing ball.

Embodiment

In Fig. 1, the two-layer slideway structure of having showed compound bearing, bearing endosome (1) is connected by the bearing compound body (2) that a two sides all has slideway with bearing ectosome (2), bearing ball (4) during work on the slideway of bearing compound body (2), bearing endosome (1) and bearing ectosome (2) all can freely roll, rotating speed is freely shared by two-layer slideway, whose resistance is little, whose burden rotating speed is just many, can reduce rotational resistance like this, reduce temperature rise, increase the service life, also improved rotating speed simultaneously greatly.

Claims (2)

1. the compound body bearing with two-layer slideway that compound bearing, bearing endosome, bearing compound body, bearing ectosome are formed from inside to outside successively, it is characterized in that: have the two-layer slideway that is different from plain bearing, rotating speed is freely shared by two-layer slideway during rotation.

2. compound bearing according to claim 1 is characterized in that: little bearing endosome and big bearing ectosome are fused into the bearing compound body that there is slideway on a two sides, utilize this compound body that interior external slideway is connected, and form complete compound bearing
