Embodiment Construction

[0026] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0027] see Figure 1 to Figure 6 As shown, according to an embodiment of the present invention, a compressor crankshaft is provided. The compressor crankshaft includes a main shaft 10 and a first eccentric circle 20, a second eccentric circle 30 and a third eccentric circle 40 arranged at intervals on the main shaft 10 in sequence, wherein the first eccentric circle 20 and / or the second eccentric circle 30 are both It is detachably arranged on the main shaft 10 . In actual use, it is necessary to set the rollers on the outer circumference of the first eccentric circle 20, the second eccentric circle 30 and the third eccentric circle 40, because the first eccentric circle 20 and / or the third eccentric circle in this embodiment The circle 40 is deta...

Abstract

The invention provides a compressor crankshaft and a compressor with same. The compressor crankshaft comprises a main shaft, a first eccentric circle, a second eccentric circle and a third eccentric circle, wherein the first eccentric circle, the second eccentric circle and the third eccentric circle are arranged on the main shaft at intervals in sequence, wherein the first eccentric circle and / or the third eccentric circle is detachably arranged on the main shaft. According to the invention, the compressor crankshaft is changed into a plurality of parts, and can overcome a problem that a roller cannot sleeve the middle eccentric circle internally, namely the second eccentric circle while the compressor crankshaft is installed; no matter how large the angle among eccentric lines of the first eccentric circle, the second eccentric circle and the third eccentric circle is, the roller has no limit in a process that the roller sleeves the first eccentric circle, the second eccentric circle and the third eccentric circle, so that necessary structure foundation is provided for producing and machining a three-stage compressor.

Description

technical field [0001] The present invention relates to the technical field of electric equipment, and more specifically, relates to a compressor crankshaft and a compressor having the same. Background technique [0002] The three-stage compressor can be applied to high-temperature refrigeration or low-temperature heating under more severe working conditions. Through the staged compression of the high-pressure ratio, the load of the compressor can be reduced and the compressor can operate normally. In order to reduce the balance weight of the compressor as much as possible, the eccentric circle of the crankshaft of the three-stage compressor is generally uniformly distributed at 120°. This arrangement of eccentric circles creates an assembly problem. The eccentric circle of the crankshaft in the middle is blocked by the upper and lower eccentric circles. The inability to fit the rollers has brought great difficulties to the assembly of the compressor. Contents of the inven...
