Abstract
The utility model discloses an externally riveted type freezer compressor oil pump which comprises a crankshaft, an upper oil blade and an oil pump shell body. The upper oil blade is mounted in the oil pump shell body in a clamping mode. The inner diameter of the head portion of the oil pump shell body is rotatably riveted with the outer diameter of the tail of the crankshaft in a matched mode, and a circular groove is formed when inner diameter of the head portion of the oil pump shell body is riveted with the outer diameter of the tail of the crankshaft. Three concave points are uniformly distributed on the circumference of the circular groove. Through the structure, standardization of crankshaft castings of an oil pumping structure of a freezer compressor is easy to achieve, and types of the crankshaft castings and utilization amount of crankshaft materials are reduced; the shaft diameter of the crankshaft is easy to thin, and high efficiency of properties of the compressor is conducive; and crankshaft components used by different accumulated thickness can be achieved just through adjusting of the length of the oil pump shell body.
Description
Technical field
The utility model relates generally to a kind of outer riveted type freezer compressor oil pump, oils in the time of realizing compressor operation.
Background technique
At present, the refrigerator compressor crankshaft structure that oils mainly contains two kinds.A kind of the material of the required bent axle of this mode is more in order to utilize bent axle itself, oiling blade as oil pump, and does not equally have the thick corresponding multiple automatic modeling crankshaft casting of compressor needs, and standardization is poor.Another inserts in the crank spindle for oil pump case, and bent axle composition oil pump mechanism, and this mode has certain narrow limitation, and oil pump case inserts in the crank spindle, causes the wall thickness reduction of crank spindle, and crankshaft strength reduces.The large Crankshaft Machining of these mode main shaft diameters of axle easily realizes, the Crankshaft Machining difficulty that the main shaft diameter of axle is little is very large, is unfavorable for high efficiency.
The model utility content
The utility model purpose is exactly in order to remedy the defective of the existing structure that oils, to provide a kind of for the outer riveted type compressor oil pump on the refrigerator.
The utility model is achieved through the following technical solutions:
A kind of outer riveted type freezer compressor oil pump, include bent axle, oiling blade and oil pump case, described oiling blade is installed in the oil pump case, described oil pump case head internal diameter cooperates rotary riveting with bent axle afterbody external diameter, form an annular groove during riveted joint, be evenly equipped with three concave points on the described annular groove circumference.
The utility model has the advantages that:
Structure easily realizes the automatic modeling crankshaft casting standardization to the utility model so that freezer compressor oils, and reduces the automatic modeling crankshaft casting kind, reduces the crankshaft material consumption; Easily realize the refinement of the bent axle diameter of axle, be conducive to the compressor performance high efficiency; Do not equally have thick employed crankshaft component, only realize by adjusting oil pump case length.

Embodiment
A kind of outer riveted type freezer compressor oil pump, include bent axle 1, oiling blade 2 and oil pump case 3, described oiling blade 2 is installed in the oil pump case 3, described oil pump case head 4 internal diameters cooperate rotary riveting with bent axle afterbody 5 external diameters, form annular groove 6 after the riveted joint, be evenly equipped with three concave points 7 on described annular groove 6 circumference.
Claims (1)
1. outer riveted type freezer compressor oil pump, include bent axle, oiling blade and oil pump case, described oiling blade is installed in the oil pump case, it is characterized in that: described oil pump case head internal diameter cooperates rotary riveting with bent axle afterbody external diameter, form an annular groove during riveted joint, be evenly equipped with three concave points on the described annular groove circumference.
