Abstract

The invention discloses an exhaust bearing pedestal assembly which comprises a bearing pedestal body. An exhaust opening is formed in the bearing pedestal body. An exhaust pipe communicated with the exhaust opening is formed in the bearing pedestal body. A plurality of expansion pipes are sequentially and coaxially distributed on the side wall of the exhaust pipe in the axial direction of the exhaust pipe. The diameter of the expansion pipes is larger than the diameter of the exhaust pipe. In the working process of a device, the gradual filtering structure formed by the expansion pipes can effectively improve the filtering effect of the exhaust bearing pedestal assembly on certain-frequency sound waves, noises in the running process of the device are reduced, and therefore overall performance of the device is further improved. The invention further discloses a screw machine with the exhaust bearing pedestal assembly.

Description

technical field [0001] The invention relates to the technical field of supporting components of a screw machine, in particular to an exhaust bearing seat assembly. The invention also relates to a screw machine using the exhaust bearing seat assembly. Background technique [0002] The exhaust bearing seat is one of the important components of the screw machine, and its structure and performance directly affect the exhaust effect during the working process of the screw machine. [0003] At present, the exhaust channel of the exhaust bearing seat of the existing screw machine is generally a straight-through channel with regular and uniform cross-section, and the exhausted gas is first exhausted through this channel to the oil separator barrel or directly to the outside of the compressor. In the exhaust process, the air pulsation noise will not attenuate in the channel with a regular cross-section, so the exhaust noise during the operation of the equipment is relatively large, ...
