Abstract
A crankshaft with an eccentric part provided with a ring groove, relating to a refrigeration compressor. The utility model mainly includes a crankshaft, an eccentric part is arranged on the crankshaft, the eccentric part is provided with an oil hole connected to the central hole and a vertical oil groove, a ring oil groove connected to the vertical oil groove is arranged at the position of the oil hole of the eccentric part. Because a ring groove is added to arrange at the position of the oil hole of the eccentric part of the crankshaft, lubricating oil discharging from the oil hole of the eccentric part passes through the vertical oil groove and then passes through the ring groove, which makes the lubricating oil flow more fully in the piston inner diameter and the eccentric part outer diameter of the crankshaft, the lubricating oil is taken into various parts of the piston inner diameter, then fine oil film is provided to protect the piston inner diameter and the eccentric part outer diameter of the crankshaft, the phenomenon of compressor scuffing due to bad lubricating is avoided.
Description
Affiliated technical field
The utility model relates to air condition compressor, specifically refers to the improvement to air conditioner compressed machine crankshaft.
Background technique
The bent axle of compressor is one of power-transmitting unit of whole compressor, also is the vitals of compressor oil-supplying system.The piston of compressor and the eccentric part of bent axle rely on oilhole and vertical oil groove of eccentric part to provide lubricant oil to be lubricated.Under the situation of fuel feeding deficiency, be easy to cause the wearing and tearing of piston inner diameter and crankshaft eccentric external diameter as piston inner diameter and crankshaft eccentric external diameter, even the phenomenon that compressor is killed takes place.
Summary of the invention
The purpose of this utility model provides the bent axle that a kind of eccentric part has annular groove, promptly sets up an annular groove at the eccentric part of bent axle, lubricant oil can be flowed between each member more fully, thereby effectively prevent because the compressor that insufficient lubrication causes is killed phenomenon.
A kind of eccentric part of the present utility model has the bent axle of annular groove, mainly comprise a bent axle, bent axle is provided with an eccentric part, this eccentric part is provided with the oilhole that communicates with center hole and vertical oil groove, it is characterized in that on eccentric part being provided with in the oil-hole location place annular oil groove that is connected with vertical oil groove.
The beneficial effects of the utility model are: after the oilhole place of the eccentric part of bent axle has set up an annular groove; the lubricant oil that flows out from the eccentric part oilhole passes through annular groove after by vertical oil groove again; make the lubricant oil can more can be fully mobile at piston inner diameter and crankshaft eccentric portion outer radius; lubricant oil is taken to the various piece of piston inner diameter; provide good oil film to protect piston inner diameter and crankshaft eccentric portion external diameter, prevent because the compressor that insufficient lubrication causes is killed phenomenon.
Description of drawings
Fig. 1 is an an embodiment's of the present utility model structural representation.
Among the figure: 1 bent axle, 2 eccentric parts, 3 oilholes, 4 vertical oil grooves, 5 annular oil grooves.
Embodiment
Now the utility model is described in further detail in conjunction with an embodiment and accompanying drawing thereof.
By Fig. 1, a kind of eccentric part has the bent axle of annular groove, and its major component is a bent axle 1, and an eccentric part 2 is arranged on the bent axle, and its eccentric part is provided with oilhole 3 and vertical oil groove 4, and oilhole 3 places on eccentric part 2 have set up an annular oil groove 5 that is connected with vertical oil groove 4.
This bent axle is owing to set up an annular oil groove at eccentric part, for lubricant oil mobile increased a passage, make the oil film state at crankshaft eccentric external diameter and piston inner diameter place desirable more, lubricating status herein is improved, and has effectively prevented owing to the not enough compressor that causes of fuel feeding is killed phenomenon.
