Abstract
The utility model discloses a splash lubrication structure used for controlling the oil circulation volume of a compressor. The splash lubrication structure comprises a crank box, a crank, a connecting rod, a piston, a piston pin and lubricating oil, wherein the piston is arranged in a cylinder hole of the crank box and is connected with the connecting rod by the piston pin; a lubricating oil supply oilway is arranged in the crank; the connecting rod is provided with a lubricating oil hole that is communicated with the lubricating oil supply oilway of the crank; the piston pin is provided with a transverse lubricating oil passage that is communicated with the lubricating oil hole of the connecting rod; and a plug is arranged in the lubricating oil supply oilway of the crank.

Summary of the invention
Technical problem to be solved in the utility model is to propose a kind of splash lubrication structure that can effectively control the compressor of the oily circulating load in the refrigeration system with the oily circulating load of control.
For solving the problems of the technologies described above, the utility model compressor comprises crankcase with the splash lubrication structure of the oily circulating load of control, bent axle, connecting rod, piston, wrist pin and lubricant oil, described piston is installed in the cylinder-bore of crankcase, and be connected with described connecting rod by described wrist pin, be provided with the lubricant oil oil feeding line in the described bent axle, described connecting rod is provided with oilhole and is communicated with the lubricant oil oil feeding line of described bent axle, described wrist pin is provided with horizontal grease channel and is connected with the oilhole of described connecting rod, in the oil drainage hole of the lubricant oil oil feeding line of described bent axle plug is installed.
The above-mentioned compressor splash lubrication structure of the oily circulating load of control, the cylndrical surface of described wrist pin is provided with the grease channel of groove as described wrist pin.
Above-mentioned compressor is provided with the grease channel of radial direction through hole as described wrist pin with the splash lubrication structure of the oily circulating load of control in the described wrist pin.
The utility model is owing to adopted above-mentioned technical pattern, when crankshaft rotating is moved, the lubricant oil of compressor bottom process oil feeding line and connecting rod lubrication oilhole under action of centrifugal force, arrive the grease channel of wrist pin, and discharge by the gap between connecting rod small end and pistion recess, under the effect of reciprocating motion of the pistons, the kinematic pair such as oil droplet, lube pistons-cylinder-bore that splash of formation.Oil droplet is discharged from the gap between connecting rod small end and pistion recess owing to splash, and the position of the oil droplet that splashes is lower, can not arrive the sealing surface of valve group, has significantly reduced participation compressor cooling circuit oil circulating load, and the refrigerating capacity and the input power of compressor are highly stable.In addition, the size of the section area by control piston pin grease channel is easy to realize the control of oil droplet oil pump capacity of splashing, thereby guarantees to have enough lubricant oil to supply with kinematic pair such as piston-cylinder hole.
