Abstract

The utility model discloses a kind of sliding sleeve including lining, it is on the basis of the built-in linear bearing of original device sliding sleeve, original linear bearing is instead of with the lining of improved, this kind of improvement avoids original linear bearing because of the comparatively large easily wearing and tearing in the gap between guide rail, need often to change bearing, affect the shortcoming of production efficiency and product quality simultaneously, there is obvious advantage.

Description

Include the sliding sleeve of lining

Technical field

The utility model relates to machine-building manufacture field, particularly relates to a kind of sliding sleeve including lining.

Background technology

Bearing is in mechanical transmission course, play parts that are fixing and reduction load coefficient of friction.Alternatively, when other parts produce relative motion each other on axle, be used for reducing the fixing parts of coefficient of friction in power transmission process and retainer shaft center, bearing is a kind of very important parts in contemporary plant equipment, its major function is supported mechanical rotary body, in order to reduce the mechanical load coefficient of friction of equipment in transmission process, by the difference of motor element frictional property, bearing can be divided into rolling bearing and sliding bearing two class.

The machinery requirement that our factory's filament dips in powder uses bearing, what complete this kind of function before this is that 2 linear bearings are fixed in a sliding sleeve inside, through use find due between guide rail and sliding sleeve by linear bearing sliding friction, but the gap between linear bearing and guide rail is larger, linear bearing also easily weares and teares, need often to change bearing, affect production efficiency and product quality simultaneously.

Summary of the invention

Given this plant drawback, after our factory makes improvements, use a kind of lining to substitute linear bearing, structure of the present utility model comprises sliding sleeve shell, characterized by further comprising 2 linings; Described lining is fixed on two terminations of sliding sleeve outer casing inner wall;

Preferably, described lining inwall has the ditch of several longitudinal direction;

Preferably, described lining is that spheroidal graphite cast-iron is made.

Wherein because lining cost is cheaper, replacement cost is lower, the ditch of several longitudinal direction of lining inwall can reduce friction area thus reduce friction, and lining material adopts spheroidal graphite cast-iron, and can to meet these parts wear-resisting, the requirement of high rigidity, in sum, the utility model has obvious advantage compared to structure in the past.

Fig. 1 is the utility model profile, in figure 1, sliding sleeve shell 2, lining;

Fig. 2 is the utility model sectional view, in figure 1, sliding sleeve shell 2, lining 3, ditch.

Detailed description of the invention

Embodiment one

As shown in Figure 1 and Figure 2, the utility model structure comprises sliding sleeve shell 1, characterized by further comprising 2 linings 2; Described lining 2 is fixed on two terminations of sliding sleeve shell 1 inwall;

Specifically, described lining 2 inwall has the ditch 3 of several longitudinal direction;

Specifically, described lining 2 is made for spheroidal graphite cast-iron.

These are only preferred embodiment of the present invention, therefore can not limit scope of the invention process according to this, the equivalence namely done according to description of the present invention changes and decoration, all should belong in the scope of the present invention's covering.
