Abstract
The utility model relates to a small cylinder seat for a full-enclosure cooling compressor. The cylinder seat has an outer frame; the center of the outer frame is provided with a shaft end which is provided with a shaft hole; the front side of the outer frame is provided with a cylinder end, and two sides of the cylinder end are provided with a gas suction muting cavity and a gas discharge muting cavity; the cylinder end is provided with a cylinder hole, a gas suction hole and a discharge hole. The small cylinder seat is characterized in that the outer frame and the shaft end are connected into a whole through a solid plate, and two sides of the solid plate are respectively provided with an oil leakage hole. The utility model can increase the strength of the cylinder seat and meanwhile prevent the entrance of refrigerating engine oil into the motor clearance, reduces the power loss, has small volume and reasonable design, is convenient to be produced and assembled, is favorable to reduce noise and vibration and is in particular suitable for the improvement of a press spring structure type cylinder seat.
Description
(1) technical field:
The utility model relates to the technological improvement of refrigeration compressor, is the small-sized cylinder block of a kind of hermetically sealed compressor.
(2) background technique:
Miniaturization is a developing direction of hermetically sealed compressor, and the size of compressor depends on the size of cylinder block to a great extent.Existing cylinder block volume is bigger, minimum Outside Dimensions is long * wide be 130 * 120mm, its basic structure has housing, center at housing is provided with spindle nose, open axis hole on the spindle nose, be provided with cylinder head in the front side of housing, the both sides of cylinder head are furnished with air-breathing silencing cavity and exhaust noise silencing chamber, have cylinder hole and suction port and exhaust port on the cylinder head, wherein housing and spindle nose are to adopt gusset to fuse, and its intensity is lower, simultaneously, refrigerator oil very easily enters motor gas-gap, reduces power.
(3) summary of the invention:
It is lower that the purpose of this utility model will solve existing cylinder block intensity exactly, refrigerator oil enters motor gas-gap easily, reduces the problem of power, simultaneously under the requirement of satisfying high-performance, low noise, reduce volume and weight, provide a kind of hermetically sealed compressor small-sized cylinder block.
Concrete scheme of the present utility model is: the small-sized cylinder block of hermetically sealed compressor, has housing, center at housing is provided with spindle nose, open axis hole on the spindle nose, front side at housing is provided with cylinder head, and the both sides of cylinder head are furnished with air-breathing silencing cavity and exhaust noise silencing chamber, have cylinder hole and suction port and exhaust port on the cylinder head, it is characterized in that: housing is to adopt the solid slab face to be connected one with spindle nose, and respectively has an oil leaking hole in solid slab face both sides.
The face thickness of solid slab described in the utility model is 3-6mm.
Axis hole center line described in the utility model on the spindle nose departs from the cylinder centerline hole 1-4mm (its effect is: reduce the side direction active force of piston to cylinder-bore) on the cylinder head.
For reducing the cylinder block volume and weight, the monnolithic case size of cylinder block is reduced into long 90-110mm in the utility model, wide 95-105mm.
For preventing that air-breathing silencing cavity and exhaust noise silencing chamber from exerting an influence to cylinder head when gland assembles, the extrusion cylinder bore deformation, air-breathing silencing cavity described in the utility model and upper end, exhaust noise silencing chamber outer wall all and between the cylinder head leave the 2-5mm gap.
The utility model is compared with traditional cylinder block, and advantage is: volume is little, and the intensity height is convenient to processing and assembling, and noise vibration is little, can prevent that refrigerator oil from entering motor gas-gap simultaneously, reduces power loss, and can improve the coefficient of performance of compressor.
(4) description of drawings:
Fig. 1 is a plan view of the present utility model;
Fig. 2 is a left view of the present utility model;
Fig. 3 is a plan view of the present utility model.
Among the figure: 1-cylinder hole, 2-suction port, 3-exhaust port, 4-limited post, the air-breathing silencing cavity of 5-, 6-exhaust noise silencing chamber, 7-axis hole, 8-oil leaking hole, 9-cylinder head, 10-spindle nose, 11-housing, 12-solid slab face, 13-gap.
(5) embodiment:
The utility model is a monolithic construction, adopts cast iron fine finishing moulding, and its bulk shape size Control is at long 90-110mm, in the wide 95-105mm.Its concrete structure is referring to Fig. 1,2,3, it has housing 11, be provided with spindle nose 10 in the center of housing 11, have axis hole 7 on the spindle nose 10, be provided with cylinder head 9 in the front side of housing 11, the upper end outer wall that the both sides of cylinder head 9 are furnished with air-breathing silencing cavity 5 and exhaust noise silencing chamber 6, two silencing cavity 5 and 6 all and leave the gap 13 of 2-5mm between the cylinder head 9.And on cylinder head 9, have cylinder hole 1 (its center line and the center line of axis hole 7 depart from 1-4mm for well) and suction port 2 (being communicated with air-breathing silencing cavity 5) and exhaust port 3 (being communicated with exhaust noise silencing chamber 6).Particularly: housing 11 adopts solid slab face 12 (its thickness is 3-6mm) to fuse with spindle nose 10 in the utility model, and respectively has an oil leaking hole 8 in the both sides of solid slab face 12, promptly constitutes the utility model.
