Embodiment Construction

[0033] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0034] Such as Figure 1 to Figure 4 As shown, a compressor crankshaft blank is composed of a hollow major shaft 1 , a solid minor shaft 2 and an eccentric sleeve 3 .

[0035] From one end to the other, the short shaft 2 consists of a welding connection section 2a, a spline section 2b and a main shaft section 2c, and the spline section 2b has spline teeth. The eccentric sleeve 3 has a shaft hole 3a inside, the shaft hole 3a deviates from the axis of the eccentric sleeve 3, and the side of the shaft hole 3a has a spline groove. One end of the short shaft 2 is passed through the shaft hole 3a of the eccentric sleeve 3; specifically, the spline section 2b of the short shaft 2 is located in the shaft hole 3a, and the spline t...

Abstract

The invention provides a rotary compressor crankshaft blank, a crankshaft blank assembling method and a crankshaft blank batch manufacturing method, and belongs to the technical field of liquid variable-volume machines. The problem that an existing rotary compressor crankshaft blank is high in manufacturing cost is solved. The compressor crankshaft blank is integrally and reasonably divided into along shaft, a short shaft and an eccentric sleeve, wherein one end of the short shaft penetrates into a shaft hole of the eccentric sleeve, and the short shaft is in close fit with the eccentric sleeve; and the long shaft and the short shaft are coaxially arranged, one end of the long shaft and one end of the short shaft are fixedly connected in a welded mode, and one end of the long shaft and the eccentric sleeve are fixedly connected in a welded mode. Materials and manufacturing processes of the long shaft, the short shaft and the eccentric sleeve can be flexibly selected according to technical requirements, and parts with various technical requirements are manufactured; and when crankshafts with different technical requirements are manufactured, parts with proper technical requirementscan be selected according to requirements for assembling, then research, development and manufacturing cost is reduced, and manufacturing efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of liquid displacement machines, and relates to a rotary compressor, in particular to a rotary compressor crankshaft blank. [0002] The invention belongs to the technical field of liquid displacement machines, and relates to a rotary compressor, in particular to a method for assembling a crankshaft blank of a rotary compressor. [0003] The invention belongs to the technical field of liquid variable displacement machines, and relates to a rotary compressor, in particular to a method for mass-manufacturing crankshaft blanks of the rotary compressor.
