Abstract
The utility model provides a split type mechanism that rubs that hinders for cross head, relates to compressor preparation technical field, sets up on the cross head outer wall, and the main part be the wearing layer of a cover on the cross head outer wall, the wearing layer be detachable, the bottom of wearing layer be provided with the card strip, the cross head outer wall on be provided with the draw -in groove, card strip detachable set up in the draw -in groove. The beneficial effects of the utility model are that: the utility model relates to a novelty, simple structure, through set up the wearing layer that can dismantle the change at the cross head outer wall, it need be to cross head overall change after the long -term wearing and tearing to have avoided, and more equitable, the elevating can be adjusted to the wearing layer simultaneously, the long -term use of being convenient for, the effect is obvious, and the practicality is good, facilitate promotion and use.
Description
Technical field
The utility model relates to compressor preparing technical field, is specifically related to a kind of Separated resistance for crosshead and rubs mechanism.
Background technique
Compressor, low-pressure gas being promoted to a kind of driven fluid machinery of pressurized gas, is the heart of refrigeration system.It sucks the refrigerant gas of low-temp low-pressure from sucking pipe, after driving piston to compress it by motor rotation, the refrigerant gas of High Temperature High Pressure is discharged to outlet pipe, for refrigeration cycle provides power, thus realize the refrigeration cycle of compression → condensation (heat release) → expand → evaporate (heat absorption), compressor is when being prepared, crosshead is absolutely necessary a kind of component, be mainly used in the connection of piston rod and connecting rod, crosshead is owing to being arranged in cylinder body, can move back and forth, therefore necessary charging-up lubricant oil in the use of reality, but only with the use of lubricant oil, its surface can not be effectively made to be effectively protected, present stage is generally all to increase wear mechanisms on the surface of crosshead, but these mechanisms be all generally be fixedly ignorant of spread upon on crosshead surface, therefore also can cause certain wearing and tearing for a long time later, whole crosshead is caused to occur damage.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of structure simple, and abrasion resistant effect is obvious, and the Separated resistance for crosshead being convenient to change rubs mechanism.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of Separated resistance for crosshead rubs mechanism, be arranged on crosshead outer wall, it is characterized in that: main body is a wearing layer covering on crosshead outer wall, described wearing layer is detachable, the bottom of described wearing layer is provided with card article, described crosshead outer wall is provided with draw-in groove, and described card article is dismountable to be arranged in draw-in groove.
Described draw-in groove bottom surface arranges inclined-plane shape, and described card article bottom surface is set to the inclined-plane with draw-in groove bottom surface same tilt angle, and described card article bottom surface is narrow compared with draw-in groove bottom surface, continues to use after facilitating the thinning rear movement of wearing layer.
One end of described card article is provided with the spacing screw mandrel that passes crosshead, facilitates mobile wearing layer, convenient.
Described spacing screw mandrel is set to invaginating, avoids protrusion and causes space waste, and collision free, more rationally.
Described wearing layer is provided with groove, is convenient in use, the delay of lubricant oil, effect is more obvious.
The beneficial effects of the utility model are: the utility model is novel in design, structure is simple, by being provided with the detachable wearing layer changed at crosshead outer wall, need after avoiding long term wear crosshead integral replacing, more rationally, wearing layer can regulate the high end simultaneously, be convenient to Long-Time Service, successful, practicability is good, is convenient to promote and use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figure 1, a kind of Separated resistance for crosshead rubs mechanism, be arranged on crosshead outer wall 1, main body is a wearing layer 2 covering on crosshead outer wall 1, wearing layer 2 is detachable, the bottom of wearing layer 2 is provided with card article 3, crosshead outer wall 1 is provided with draw-in groove 4, card article 3 is dismountable to be arranged in draw-in groove 4, after arranging like this, by being provided with the detachable wearing layer 2 changed at crosshead outer wall 1, need after avoiding long term wear crosshead integral replacing, draw-in groove 4 bottom surface arranges inclined-plane shape, card article 3 bottom surface is set to the inclined-plane with draw-in groove 4 bottom surface same tilt angle, card article 3 bottom surface is narrow compared with draw-in groove 4 bottom surface, continue after facilitating the thinning rear movement of wearing layer 2 to use, one end of card article 3 is provided with the spacing screw mandrel 5 that passes crosshead, facilitate mobile wearing layer 2, convenient, spacing screw mandrel 5 is set to invaginating, avoid protrusion and cause space waste, and collision free, more reasonable, wearing layer 2 is provided with groove 6, be convenient in use, the delay of lubricant oil, effect is more obvious.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
