Problems solved by technology

However, since the compressor has certain requirements on the strength of the eccentric shaft and must meet the minimum lubrication capacity, the method of reducing the diameter of the eccentric shaft is limited.

Embodiment Construction

[0022] like figure 2 As shown, the reciprocating piston type hermetic compressor of the present invention includes housing 3, inner exhaust pipe 4, motor stator 8, motor rotor 9, crankcase 11, crankshaft 10, eccentric shaft 13, connecting rod 14, piston pin 15, piston 16. Valve group 18, suction muffler 19, exhaust pipe 20 and ball bearing assembly 1, the connecting rod 14 is an integral connecting rod, and the ball bearing assembly 1 is assembled between the eccentric shaft 13 and the hole of the connecting rod big end 12, The eccentric shaft 13 and the connecting rod 14 are connected. Obviously, when the hermetic compressor adopting the ball bearing structure of the present invention is in operation, the original sliding friction between the eccentric shaft 13 and the big head 12 of the connecting rod 14 is transformed into rolling friction, which further reduces the mechanical loss.

Abstract

The invention discloses a reciprocating piston-type sealing compressor, which comprises housing, a motor, a crank shaft, a crank shaft case, a connecting bar, a piston, a valve bank, an aspiratory muffler and a ball bearing component, wherein, an eccentric shaft on the upper end of the crank shaft is connected with a big-end hole of the connecting bar via the ball bearing component, and the ball bearing component is internally provided with two rows of balls. Therefore, the friction between the eccentric shaft and the connecting bar is converted into rolling friction, thus further deducing the mechanical loss of the position and further enhancing the efficiency of the complete machine of the compressor. Meanwhile, as the design of two-row balls is adopted in the structure, smaller balls can be used and the radial dimension of smaller ball bearing component is used for meeting the needs of integrant loading strength; in addition, a lubricating oil hole is easy to be arranged between the two-row balls, thus ensuring sufficient lubrication of the balls.

Description

Technical field [0001] The invention relates to a hermetic compressor, in particular to a reciprocating piston hermetic compressor which can be used in household and small refrigeration systems. Background technique [0002] The existing hermetic compressor is installed in a closed shell, figure 1 Shown is one of the existing hermetic compressors, which includes a housing 3, an inner exhaust pipe 4, a motor stator 8, a motor rotor 9, a crankshaft 10, a crankcase 11, a crankshaft eccentric shaft 13, a connecting rod 14 (including connecting rod big end 12 and connecting rod small end 17), piston pin 15, piston 16, valve group 18, suction muffler 19 and exhaust pipe 20, crankshaft 10 with eccentric shaft 13 is assembled in the cylinder body On the crankshaft hole, the crankshaft 10 pushes the connecting rod 14-piston 16 to reciprocate, and the eccentric shaft 13 and the big end of the connecting rod 12 are connected together with an appropriate gap. When the compressor is wo...
