An orbiting scroll plate driving assembly provided by the present application includes a main shaft (), a tail driving shaft (), and an eccentric shaft sleeve (). The tail driving shaft () is eccentrically connected to the main shaft (), and the eccentric shaft sleeve () is rotatably sleeved on the tail driving shaft (). The orbiting scroll plate driving assembly further includes a limiting portion (). The limiting portion () is disposed on the tail driving shaft (), and provided with a first limiting portion protrusion (). The eccentric shaft sleeve () is provided with an eccentric shaft sleeve groove (). The first limiting portion protrusion () is correspondingly inserted into the eccentric shaft sleeve groove. A circumferential size of the eccentric shaft sleeve groove () is larger than a circumferential size of the first limiting portion protrusion (). By providing the limiting portion () on the tail driving shaft (), and providing a mortise joint structure between the limiting portion () and the eccentric shaft sleeve (), the circumferential movement and axial movement of the eccentric shaft sleeve () can be confined, and the assembly and processing are simple. Further, a scroll compressor is disclosed.

Orbiting scroll plate driving assembly and scroll compressor

Scroll compressor, a vehicle air conditioner and a vehicle are disclosed. The scroll compressor includes a first end cover, a casing and a crankshaft. The casing is provided with a supporting portion having a first bearing mounting portion; the first end cover is provided with a second bearing mounting portion; a first end of the crankshaft is arranged in the first bearing mounting portion through a first bearing; a second end of the crankshaft is arranged in the second bearing mounting portion through a second bearing; and the first bearing mounting portion and the second bearing mounting portion cooperate with each other to form an axial limitation on the crankshaft.

Scroll compressor, vehicle air conditioner and vehicle

Disclosed are a method and a device for balancing crankshaft deformation e, a crankshaft with counterweights determined according to the method, and a scroll compressor using the crankshaft. The method includes: determining a component centrifugal force required by a counterweight to overcome the crankshaft deformation caused by both an orbiting scroll centrifugal force and a gas force; and determining the counterweight according to the component centrifugal force. The counterweight is arranged on the crankshaft.

Method and device for balancing crankshaft deformation, crankshaft, and scroll compressor

Scroll compressor and a vehicle having the same. The scroll compressor includes: a support and an orbiting scroll assembly, the orbiting scroll assembly being movably provided on the support; a partition structure, provided between the support and the orbiting scroll assembly, a first bearing chamber being formed between the partition structure and the orbiting scroll assembly, a second bearing chamber being formed between the partition structure and the support, the orbiting scroll assembly being provided with a first through hole in communication with the first bearing chamber, and the support being provided with a second through hole in communication with the second bearing chamber; and a first crankshaft), passing through the partition structure, a first communication passage through which the first bearing chamber is in communication with the second bearing chamber is formed between the first crankshaft and the partition structure.

Scroll compressor and vehicle having the same

The present disclosure discloses a compressor, an air conditioning system and a vehicle. The compressor comprises a compression cavity, and further comprises a flash cavity capable of flashing a liquid refrigerant, and a communicating passage that communicates a flash cavity gas outlet of the flash cavity and an enthalpy increasing gas supply port of the compression cavity; the flash cavity is provided with an inlet and a liquid outlet, the inlet of the flash cavity is configured to be communicated with an outlet of a condenser, and the liquid outlet of the flash cavity is configured to be communicated with an inlet of an evaporator. The air conditioning system comprises the compressor, the evaporator, the condenser, a flasher, and various pipelines for connecting the entire system. The compressor comprises the flash cavity with a flash function, so that the entire enthalpy increasing system is simpler, the space for an additional flasher structure is saved, and the enthalpy increasing system is more suitable for a vehicle-mounted air conditioning system with a limited space. The present disclosure also discloses a vehicle, particularly an electric vehicle, using the air conditioning system.

Compressor, air conditioning system and vehicle

Provided is a variable-capacity mechanism for a scroll compressor. The scroll compressor includes a compression mechanism. The compression mechanism includes a fixed scroll and an orbiting scroll for defining a series of compression cavities. The variable-capacity mechanism includes: a discharge channel, suitable for communicating a medium-pressure compression cavity in the compression cavities with a low-pressure region; blocking members, suitable for selectively opening or closing the discharge channel; an actuation device, including an execution member, the blocking members being connected to the execution member so as to selectively open or close the discharge channel along with the actions of the execution member. Multiple blocking members are connected to a single execution member so as to synchronously move along with the actions of the single execution member. By the variable-capacity mechanism, action synchronization of multiple blocking members can be reliably implemented. Provided is a scroll compressor including the variable-capacity mechanism.
