Embodiment Construction

[0042] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0043]It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0044] It should also be noted that the orientation terms such as left, right, up and down in the embodiments of the present application are only relative concepts or refer to the norma...

Abstract

The invention provides a shaft structure applied to a compressor, the compressor with the shaft structure, an air conditioning device with the compressor and a vehicle with the air conditioning device. The shaft structure comprises a first shaft and a second shaft. A fixing hole is formed in the end face of one end of the first shaft and eccentrically arranged relative to the first shaft. One end of the second shaft is inserted into the fixing hole and is in interference fit with the fixing hole; and an unloading part is arranged on the inner side wall of the fixing hole and / or the circumferential surface of a partial section, extending into the fixing hole, of the second shaft. According to the shaft structure provided by the invention, the unloading part is arranged on the inner side wall of the fixing hole and / or the circumferential surface of the partial section, extending into the fixing hole, of the second shaft, so that interference connection expansion force caused by interference connection of the second shaft and the fixing hole can be reduced or even completely unloaded through the unloading part; therefore, the geometric tolerance deterioration of the roundness and cylindricity of the excircle of the first shaft can be effectively avoided, and the failure of the first shaft is further prevented.

Description

technical field [0001] The application belongs to the technical field of refrigeration and heating equipment, and more specifically relates to a shaft structure applied to a compressor, a compressor, an air conditioner and a vehicle. Background technique [0002] In today's air-conditioning devices, such as vehicle-mounted air-conditioning devices, in order to achieve high efficiency, low noise and smooth operation, scroll compressors are usually selected. In a scroll compressor, it usually includes movable scroll, fixed scroll, motor, eccentric shaft and other components; among them, one end of the eccentric shaft is connected with the rotor of the motor, and the other end of the eccentric shaft is the eccentric part of the eccentric shaft. The scroll is connected eccentrically. After the motor is started, the eccentric shaft rotates under the drive of the rotor of the motor. Correspondingly, the fixed scroll is in a relatively static state, and the movable scroll is driven...
