Abstract

The utility model discloses an external-embedded plastic bearing. The external-embedded plastic bearing comprises a bearing (1) and a bearing sleeve (1-1) which is externally embedded on the bearing (1) to avoid direct contact between the bearing (1) and a workpiece (2). When used, the external-embedded plastic bearing reduces abrasion of the bearing and clash of the workpiece, decreases or avoids corrosion from external environment on the bearing, and therefore prolonging service life of the bearing.

Description

Outer embedding plastic bearing

One, technical field

The utility model relates to a kind of electromechanical equipment component, is specifically related to bearing.

Two, background technique

Bearing generally is made up of inner ring, outer ring, rolling element and retainer, and wherein the effect of inner ring is to match with axle, and rotates together with the axis; The outer ring effect is to match with bearing support, plays a supportive role; Rolling element is uniformly rolling element to be distributed between inner ring and the outer ring by means of retainer; Its shape size and quantity directly affect the usability and the life-span of rolling bearing; Retainer can make rolling element evenly distribute, and prevents that rolling element from coming off, guiding rolling element rotation lubricate.At present generic central frame bearing exist directly contact with workpiece surface, surface friction drag is big, the bigger deficiency of sound during rolling, and under particular job environment, does not possess erosion-resisting function.

Three, summary of the invention

The purpose of the utility model provides a kind of outer embedding plastic bearing, contacts with the direct of workpiece to avoid bearing, reduces the wearing and tearing of bearing, reduces or avoids bearing corroded by external environment, thereby improve bearing working life.

For realizing above purpose, the outer embedding plastic bearing of the utility model comprises bearing and bearing housing, and bearing housing is embedded in outward on the bearing, contacts with the direct of workpiece to avoid bearing.

The characteristics of above-mentioned outer embedding plastic bearing: resistance to wear through between bearing and workpiece, increasing one deck, quiet bearing housing, when the bearing centre frame is embraced the folder workpiece, can avoid the direct bump of bearing and workpiece, reduced the wearing and tearing of bearing and colliding with of workpiece; In addition, under acidity or ocean environment, the plastic shaft bearing sleeve has the certain protection effect to bearing, reduces or avoids bearing corroded by external environment, has directly improved the working life of bearing.Should also have the advantage that making is simple, operation and maintenance is convenient, be beneficial to popularization by outer embedding plastic bearing.

Four, description of drawings

Fig. 1 is the outer embedding plastic bearing master cross-sectional schematic of the utility model.

When Fig. 2 is the outer embedding plastic bearing work of the utility model and workpiece, cylinder arrangement schematic representation.

Five, embodiment

Below in conjunction with accompanying drawing and embodiment the outer embedding plastic shaft of the utility model is made further explain.

Fig. 1～shown in Figure 2; The outer embedding plastic bearing of the utility model comprises bearing 1 and bearing housing 1-1, and bearing housing 1-1 adopts plastics to process, and bearing housing 1-1 is embedded in outward on the bearing 1; Avoiding bearing 1 under cylinder 3 effect, to contact, thereby the wearing and tearing of bearing 1 and colliding with of workpiece 2 have been reduced with the direct of workpiece 2.

Claims (1)

1. outer embedding plastic bearing, it is characterized in that: it comprises bearing (1) and bearing housing (1-1), bearing housing (1-1) is outer to be embedded on the bearing (1), to avoid direct contact of bearing (1) and workpiece (2).
