Description

Novel compressor crankshaft
Technical field
The utility model relates to compressor apparatus technical fields, can be improved oil effect and reinforcement more particularly, to one kind The novel compressor crankshaft of lubricant effect during rotation.
Background technique
Compressor is generally made of body, motor, cylinder body, piston, control equipment and cooling system;Wherein, motor and work Plug is usually connected by crankshaft.Crankshaft includes short axle and long axis, and wherein long axis is connected with the rotor of motor, and short axle passes through company Bar is connect with piston.Important component of the crankshaft as connection motor and piston drives crank rotation by motor, and then drives and live Plug movement.During rotation, long axis will generate phase mutual friction to crankshaft between the crankshaft hole wall for installing cooperation with it;Short axle will be with Phase mutual friction is generated between its connecting rod cooperated;And piston will generate phase mutual friction between inboard wall of cylinder block during the motion. Rubbed more readily raising compressor power consumptions, reduce the compressor service life.
Therefore, design it is a kind of can be improved oil effect and reinforce lubricant effect during rotation new type compressor it is bent Axis just seems very necessary.
Utility model content
The utility model is to overcome in the prior art, and during rotation, lubricant effect is poor for crankshaft, is easy to happen and rubs The problem of wiping, provides a kind of raising and oils and effect and reinforces the novel compressor crankshaft of lubricant effect during rotation.
To achieve the above object, the utility model uses following technical scheme:
A kind of novel compressor crankshaft, including main shaft, from axis and set on main shaft and from the connector between axis;It is described from axis Interior to be equipped with oil supply gallery, the main shaft is equipped with annular oil groove far from the end outer surface of connector side, is additionally provided in main shaft Oil inlet through-hole, the oil inlet through-hole are in communication with the outside;The oil supply gallery through-connections are equipped with tiltedly oil from axis outer surface Slot, oblique oil groove are connected to by vertical through hole with oil supply gallery.
In the utility model, main shaft is designed far from the end of connector side instead of traditional oil-Absorbing nozzle, so that in song Axis can realize lubricant effect during rotation, without connecting oil-Absorbing nozzle.From the oblique oil groove on axis outer surface, cut is designed, Improve the effect that oils.The annular oil groove that spindle nose outer surface is equipped with is for reinforcing lubricant effect.The utility model has It can be improved the characteristics of oiling effect and reinforcing lubricant effect during rotation.
Preferably, main shaft lateral surface is equipped with helical oil groove, described helical oil groove one end is connected to oil supply gallery, spiral The oil groove other end is connected to oil inlet through-hole.Lubricating oil enters in oil supply gallery by oil inlet through-hole and helical oil groove.
Preferably, parallel with from axis extending direction from the oil supply gallery in axis.Oil supply gallery is put down with from axis extending direction Row, facilitates processing, save the cost.
It is connected to preferably, being additionally provided with the vertically gas vent with main shaft outer surface, gas vent on main shaft with oil inlet through-hole. Gas is oiled by exhaust hole toward outlet realization.
Preferably, being equipped with oil leak through-hole at connector marginal surface.Oil leak through-hole is for increasing in crank rotation, profit Flow effect of the lubricating oil outside crankshaft.
Preferably, end of the main shaft far from connector side is in cone.It designs instead of tradition the end of cone Oil-Absorbing nozzle so that crankshaft can reach oil absorbing effect, easy to operate, save the cost without connecting oil-Absorbing nozzle.
Therefore, the utility model has the following beneficial effects: (1) is from the oblique oil groove on axis outer surface, cut design is improved The effect that oils;(2) annular oil groove that spindle nose outer surface is equipped with strengthens the lubrication effect of crankshaft during rotation Fruit;(3) structure is simple, facilitates processing.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the utility model;
Fig. 2 is a kind of left half sectional view of the utility model;
Fig. 3 is a kind of right half sectional view of the utility model.
In figure: main shaft 1, from axis 2, connector 3, oil supply gallery 4, annular oil groove 5, oil inlet through-hole 6, oblique oil groove 7, spiral oil Slot 8, gas vent 9, oil leak through-hole 10.
Specific embodiment
The utility model is further described with specific embodiment with reference to the accompanying drawing:
Embodiment: a kind of novel compressor crankshaft as shown in Figure 1 to Figure 3, including main shaft 1, from axis 2 and be set to main shaft and From the connector 3 between axis;It is described that oil supply gallery 4, end outer surface of the main shaft far from connector side are equipped with out of axis It is equipped with annular oil groove 5, is additionally provided with oil inlet through-hole 6 in main shaft, the oil inlet through-hole is in communication with the outside;The oil supply gallery passes through Connector is worn, is equipped with oblique oil groove 7 from axis outer surface, oblique oil groove is connected to by vertical through hole with oil supply gallery.
In addition, main shaft lateral surface is equipped with helical oil groove 8, described helical oil groove one end is connected to oil supply gallery, spiral oil The slot other end is connected to oil inlet through-hole.Lubricating oil enters in oil supply gallery by oil inlet through-hole and helical oil groove.
It is parallel with from axis extending direction from the oil supply gallery in axis.Oil supply gallery is parallel with from axis extending direction, convenient to add Work, save the cost.
In addition, being additionally provided with the vertically gas vent 9 with main shaft outer surface on main shaft, gas vent is connected to oil inlet through-hole.Gas Body is oiled by exhaust hole toward outlet realization.Oil leak through-hole 10 is equipped at connector marginal surface.Oil leak through-hole is for increasing In crank rotation, flow effect of the lubricating oil outside crankshaft.
As shown in Fig. 2, main shaft right part is in cone.The end of cone is designed instead of traditional oil-Absorbing nozzle, so that Crankshaft can reach oil absorbing effect, easy to operate, save the cost without connecting oil-Absorbing nozzle.
The working method of the utility model is as follows:
Crankshaft during rotation, lubricating oil initially enters oil inlet through-hole, and the gas in oil inlet through-hole passes through exhaust Hole oils toward outlet realization.Lubricating oil enters in oil supply gallery using helical oil groove.Lubricating oil in oil supply gallery is being centrifuged It under the action of power, is thrown away by oil supply gallery port, forms good lubricant effect.
