Abstract

The utility model relates to a piston compressor cross head structure, including the cross head pin, set up in the crosshead body in the cross head pin outside, set up the main stress surface and the vice stress surface of terminal surface about the crosshead body, cross head pin microcephaly terminal surface is provided with the gland, there is the lock washer in the gland outside through the bolt fastening, cross head pin microcephaly terminal surface is connected with the sealed steel sheet of using that prevents the cross head pin to withdraw from. The beneficial effects of the utility model are that: simple structure, the cross head pin condition of droing does not take place for convenient to use, and the function is good, improves work efficiency.

Description

Piston compressor cross head design
Technical field
The utility model relates to a kind of piston compressor cross head design.
Background technique
Compressor one section of cylinder crosshead pin in running comes off suddenly, causes the equipment accident of the damage of components such as connecting rod, connecting rod CONCENTRIC REDUCER watt, cross head shoes.
Crosshead pin and crosshead body assemble exists certain design problem: it is not interference fit that (1) antirotation keys between crosshead pin and crosshead body designs, and makes crosshead pin and crosshead body there is possibility in relative rotation; (2) on crosshead pin, turnbuckle only has one, and is positioned at the center of pin, once occur to loosen, when lock washer lost efficacy, can deviate within a short period of time; (3) fin strength on lock washer is inadequate, and once bolt looseness relative movement, the fin on lock washer can break and lose anti-rotation effect under the effect of shearing force.
Model utility content
The technical problems to be solved in the utility model is: based on the problems referred to above, provides a kind of piston compressor cross head design.
The utility model solves the technological scheme that its technical problem adopts: a kind of piston compressor cross head design, comprise crosshead pin, be arranged at the crosshead body outside crosshead pin, the main stress face being arranged at crosshead body upper and lower end face and secondary stress surface, the little head end end face of crosshead pin is provided with gland, be bolted lock washer outside gland, the little head end end face of crosshead pin is connected with the sealing steel plate stoping crosshead pin to exit.
Further, steel plate is circular, and steel plate is secured by bolts on crosshead body.
The beneficial effects of the utility model are: structure is simple, easy to use, crosshead pin dropping situations does not occur, goes on well, increase work efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Wherein: 1. crosshead pin, 2. crosshead body, 3. main stress face, 4. main stress face, 5. gland, 6. lock washer, 7. steel plate.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of piston compressor cross head design as shown in Figure 1, comprise crosshead pin 1, be arranged at the crosshead body 2 outside crosshead pin 1, the main stress face 3 being arranged at crosshead body 2 upper and lower end face and secondary stress surface 4, the little head end end face of crosshead pin 1 is provided with gland 5, be bolted lock washer 6 outside gland 5, the little head end end face of crosshead pin 1 is connected with the sealing steel plate 7 stoping crosshead pin 1 to exit.
On crosshead body, crosshead pin stub end end face evenly attacks 4 M10 silk holes, does the circular steel plate of one piece of thickness 6mm, bores the bolt hole of 4 diameter 12mm, sheet-steel cover on end face, with M10 bolt evenly tightly, stops crosshead pin to exit with steel plate.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
