Description

Изобретение относится к компрессоростроению.The invention relates to compressor engineering.

Известны роторные компрессоры, содержащие корпус, эксцентрично размещенный в нем и установленный на опоре полый ротор, приводной вал, шарнирно закреплен- $ ные лопатки и нагнетательный канал [1].Rotary compressors are known that include a housing eccentrically placed in it and a hollow rotor mounted on a support, a drive shaft, articulated blades and a discharge channel [1].

В известных компрессорах в месте соединения лопаток с ротором происходит их быстрый износ, что снижает надежность.In known compressors at the junction of the blades with the rotor, their wear is rapid, which reduces reliability.

Цель изобретения — повышение надежности. 10The purpose of the invention is to increase reliability. 10

Указанная цель достигается тем, что приводной вал снабжен поводками, а лопатки закреплены на' роторе и дополнительно шарнирно соединены с поводками.This goal is achieved by the fact that the drive shaft is equipped with leads, and the blades are mounted on the rotor and additionally pivotally connected to the leads.

Кроме того, нагнетательный канал может 15 быть выполнен в опоре.In addition, the discharge channel may 15 be made in the support.

На фиг. 1 изображен компрессор, продольный разрез; на фиг. 2 — то же, поперечный разрез.In FIG. 1 shows a compressor, a longitudinal section; in FIG. 2 - the same, transverse section.

Роторный компрессор содержит корпус 1, эксцентрично размещенный в нем и установленный на опоре 2 полый ротор 3, приводной вал 4, шарнирно закрепленные ло2 патки 5 и нагнетательный канал 6. Приводной вал 4 снабжен поводками 7, а лопатки 5 закреплены на роторе 3 и дополнительно шарнирно соединены с поводками 7. Нагнетательный канал 6 может быть выполнен в опоре 2.The rotary compressor comprises a housing 1, an eccentric placed in it and mounted on a support 2, a hollow rotor 3, a drive shaft 4, articulated lo2 patches 5 and a discharge channel 6. The drive shaft 4 is equipped with leashes 7, and the blades 5 are mounted on the rotor 3 and additionally pivotally connected to the leashes 7. The discharge channel 6 can be performed in the support 2.

При работе компрессора вал 4 вращается по часовой стрелке. 'Вращение ротора 3 и перемещение лопаток 5 обеспечивается поводками 7.When the compressor is operating, the shaft 4 rotates clockwise. 'The rotation of the rotor 3 and the movement of the blades 5 is provided by leashes 7.

Шарнирное соединение лопаток с поводками уменьшает их износ и повышает надежность.The swivel connection of the blades with leashes reduces their wear and increases reliability.

Claims

(54) ROTARY COMPRESSOR The invention relates to a compressor engineering. Rotary compressors are known, comprising a housing, an eccentric housed rotor mounted on a support, a drive shaft, hinged blades and discharge channel 1. In known compressors, they rapidly wear at the junction of the blades with a rotor, which reduces reliability. The purpose of the invention is to increase reliability. This goal is achieved by the fact that the drive shaft is provided with leads, and the blades are fixed on the rotor and additionally pivotally connected to the leads. In addition, the discharge channel can be made in the support. FIG. 1 shows a compressor, a longitudinal section; in fig. 2 - the same cross section. The rotary compressor includes a housing 1, an eccentric housed in it and mounted on a support 2 a hollow rotor 3, a drive shaft 4, pivotally fixed blades 5 and a discharge channel 6. The drive shaft 4 is equipped with drivers 7, and the blades 5 are fixed on the rotor 3 and additionally hinged connected to the drivers 7. The discharge channel 6 can be made in the support 2. When the compressor is in operation, the shaft 4 rotates clockwise. The rotation of the rotor 3 and the movement of the blades 5 is provided by the leads 7. Swiveling the blades with the leads reduces their wear and increases reliability. Claim 1. Rotary compressor, comprising a housing, eccentrically placed in it and mounted on a support hollow rotor, drive shaft, hinged blades and discharge channel, characterized in that, in order to improve reliability, the drive shaft is equipped with drivers, and the blades are fixed on the rotor and additionally pivotally connected with the leads.

2. A compressor according to claim 1, characterized in that the discharge channel is provided in a support.
