Abstract

The utility model relates to a pushing block in a movable electromagnet suspended beam of hoisting machinery, and in particular to a bearing-embedded pushing block. The bearing-embedded pushing block is characterized in that a bearing (2) is arranged in the inner hole of the guide block (3), a trapezoidal thread matching with a lead screw is arranged in the bearing (2), and an end surface of each end of the guide block (3) and the bearing (2) is fixed on a connecting plate (1). Since only the bearing of the embedded bearing pushing block is adopted as a quick-wear part, service lives of the lead screw and other parts are effectively prolonged and the production cost is reduced.

Description

Embedded bearing pushing block

Technical field

The utility model relates to the pushing block in the Mobile electromagnetic drop in beam in a kind of Hoisting Machinery, specifically relates to a kind of embedded bearing pushing block.

Background technique

The pushing block of prior art is integral manufacturing processing, steel product, and during normal operation, pushing block and leading screw friction slip, pushing block and leading screw serious wear, working life is short.

The model utility content

The purpose of this utility model is to provide a kind of above-mentioned prior art shortcoming that overcomes, a kind of embedded bearing pushing block of long service life;

For achieving the above object, the technological scheme that the utility model adopts is: this embedded bearing pushing block, comprise guide pad, it is characterized in that: in the guide pad endoporus, be furnished with bearing, brearing bore is shaped with the trapezoidal thread that matches with leading screw, and the end face of an end of guide pad, bearing is fixed on connecting plate;

Described a kind of embedded bearing pushing block, it is characterized in that: bearing is at one that is fixed with connecting plate, and its excircle is provided with convex shoulder, and associated guide pad endoporus is provided with the shrinkage pool matched with convex shoulder accordingly;

Described a kind of embedded bearing pushing block is characterized in that: be provided with the screw be connected with brearing bore on the circumference of guide pad, be furnished with respectively oil gun in screw;

Described a kind of embedded bearing pushing block, it is characterized in that: described bearing is sliding bearing.

The utility model beneficial effect compared with prior art: the utility model, owing to adopting embedded bearing pushing block, only using bearing as easily damaged parts, has effectively extended the working life of other parts such as leading screw, has reduced user cost.
