Description
Technical field
The present invention relates to a kind of refrigeration compressor, particularly vehicle mounted electric refrigerating compressor for refrigerator.
Background technology
Refrigeration compressor includes the casing 9 closed and the core part in casing, in the casing of closing
Bottom storage has the refrigerator oil of lubrication, and bent axle 13 afterbody in movement is immersed in refrigerator oil.Bent axle
13 rear indoor designs have the oilhole 141 of inclination, through linked hole 142 and the helical oil groove in stage casing in stage casing
143 are connected, then are connected with the helical oil groove 16 in crankshaft eccentric portion 11 through the linked hole 144 of epimere.Refrigeration
During compressor starts work, crankshaft high-speed rotates, and the refrigerator oil bottom compressor housing is at the work of centrifugal force
With the lower helical oil groove 143 supplying stage casing through the internal linked hole 141 of bent axle 13 rear, helical oil groove promotes cold
Freeze machine oil up, supply the helical oil groove 16 in crankshaft eccentric portion 11 through epimere oilhole 144, it is achieved moving component
Lubrication.
Starting performance and the life-span of compressor are closely bound up with lubricant effect, lubricate the most abundant then compressor start
The easiest, the compressor life-span is the longest.But when compressor is just started working, speed of crankshaft the most sufficiently high it
Before, the moving component of movement is dry, does not has lubricating oil to be lubricated, and causes starting friction resistance big,
Starting difficulty, therefore it is required that the motor in compressor has bigger starting torque.During simultaneously as start
There is no the lubrication of lubricating oil, easily cause heavy wear, reduce the working life of compressor.
Summary of the invention
The technical problem to be solved in the present invention is: providing a kind of refrigeration compressor, it can be when compressor start
Offer lubricating oil is lubricated.
The present invention solves the solution of its technical problem:
There is the refrigeration compressor of oil storage tank, bent axle is designed with oil supply system, the spiral shell in crank spindle portion 13
Revolve and on the helical oil groove 16 in oil groove 143 and crankshaft eccentric portion 11, be designed with the groove storing lubricating oil, then,
Oil storage tank 182,183 and 181 is arranged in the helical oil groove 143 and 16 of bent axle.
As optimization, the present invention is designed with oil storage tank 182,183 and on bent axle helical oil groove 143 and 16
181, collect the lubricating oil of residual on lubricant passage way when compressor quits work, then, when compressor again
During start work, the lubricating oil in oil storage tank 182,183 and 181 is got rid of rapidly under gentle centrifugation power effect
Going out, each friction of motion of fast lubricant is secondary.Ensure that compressor starts the preferable lubrication of moment acquisition,
Reduce the starting torque of compressor electric motor, reduce simultaneously and start the abrasion that moment dry friction causes, prolong well
Grow the working life of compressor.The present invention can be used for the various occasion needing Piston Refrigerant Compreessor.

Detailed description of the invention
Below with reference to embodiment and accompanying drawing, the technique effect of design, concrete structure and the generation of the present invention is entered
The description that row is clear, complete, to be completely understood by the purpose of the present invention, feature and effect.Literary composition is previously mentioned
Oil storage tank, the most singly refers to the blind hole oil groove of the inclination of cylinder, and refers to change according to being embodied as situation
Become the shape of oil storage tank, the quantity of oil storage tank or the position of oil storage tank, reach more excellent oil storage effect
And lubricant effect.Each technical characteristic in the invention, permissible on the premise of the most conflicting conflict
Combination of interactions.
With reference to the possible embodiments that Fig. 1, Fig. 1 are the present invention, it is provided that a kind of refrigeration being designed with oil storage tank
Compressor crankshaft structure, it includes a bent axle body, the eccentric axial portion 11 of bent axle body and changeover portion 130 upper and lower
End is equipped with oil storage tank.Three oil storage tanks are cylindrical blind hole design.The oil storage blind hole 181 of eccentric axial portion
Being arranged on the helicla flute in crankshaft eccentric portion, the angle axial with crankshaft eccentric portion is 45 °, oil storage blind hole 182
With the 183 top and bottom intersections being separately positioned on supporting section 131 and changeover portion 130, blind hole and d-axis
The angle of portion 13 axis is 45 °.Three oil storage blind holes are arranged down from opening part and are made lubricating oil in action of gravity
Under be stored in blind hole.Second oil circuit 143 is located at supporting section 131 and changeover portion 130 with helicla flute form
Top layer, the opening of oil storage blind hole 182 and 183 is positioned on helicla flute.
The grease chamber set in described eccentric axial portion 11 is connected by linked hole 145 and linked hole 144, linked hole
The opening of 144 is positioned at the top of the second oil circuit 143.Motor shaft part 132 and oil suction section 133 internal run-through
First oil circuit 141 is connected by linked hole 142 and the second oil circuit 143, and the opening of linked hole 142 is positioned at the
The bottom of two oil circuits 143.
Representing that one of the present invention uses example in conjunction with reference to Fig. 3, Fig. 3, the crankcase 5 of this compressor is pacified
Being loaded on housing 9 internal, crankcase 5 is provided with cylinder block 52 and crankshaft bearing seat 51.The d-axis portion of the present invention
13 axis holes passing crankcase 5, by being only positioned at the plane of crankshaft bearing seat 51 end face and balance portion 12 end face
Thrust bearing contacts location, and the supporting section 131 comprising changeover portion 130 is positioned at crankshaft bearing seat 51.Motor
Shaft part 132 and oil suction section 133 are positioned at outside crankshaft bearing seat 51, and motor stator 23 and coil 22 thereof are installed on
On crankcase 5 and make rotor 21 hot jacket in the motor shaft part 132 in d-axis portion 13.Oil suction section 133 times
End stretches into the refrigerator oil liquid level bottom housing 9.In piston 4 is placed in cylinder and by connecting rod 41 and eccentric shaft
Portion 11 connects.The rotation of rotor 21 drives d-axis portion 13 to rotate, and makes to be enclosed within the company of eccentric axial portion 11
Bar 41 drives piston 4 reciprocating.Coil 22 is by current supply line 24 and is located at the outer lateral body of housing 9
Junction block 25 provides electric current after switching on power.This compressor arrangement also includes the suction being located at cylinder block 52 end face
Air valve plate 61 and exhaust valve plate 62 and cylinder head 7, cylinder head 7 connects an air suction silencer 8.
Work process is:
When the rotor 21 of compressor rotates, bent axle rotates, under the influence of centrifugal force, and refrigerator oil meeting
Linked hole 142 is arrived along the first oil circuit 141 overflow.Second oil circuit 143 of helicla flute shape is by crankshaft bearing
Seat 51 surrounds and becomes pipeline, the second oil circuit 143 spiral-shaped contrary with motor steering, to refrigerator oil shape
Become motive force upwards, make refrigerator oil rise arrival linked hole 144 from linked hole 142 along the second oil circuit 143.
The grease chamber 146 that refrigerator oil sets in entering eccentric axial portion 11 through linked hole 145 after arriving linked hole 144.
In grease chamber 146, the refrigerator oil of part can flow to axle portion table by the oil groove hole 15 on eccentric axial portion 11 axial plane
