Problems solved by technology

The disadvantages of the spring buffer are: 1. Due to the existence of self-vibration, it is easy to transmit low-frequency vibration
2. The damping is too small, and the critical damping ratio is generally only 0.005, so resonance will occur in the range close to the equipment frequency
3. Since the spring is prone to damage due to fatigue during use, its working condition is not very stable

Abstract

The invention discloses an aerodynamic damping buffer. The aerodynamic damping buffer comprises a cylinder (1) and further comprises a piston assembly (12) and a pull rod (2), wherein the piston assembly (12) is installed at one end of the pull rod (2) and located inside the cylinder (1); the outer wall of the piston assembly (12) makes contact with the inner wall of the cylinder (1); a ventilation groove (11) is formed in the inner wall of the cylinder (1) in the length direction of the cylinder (1). The novel buffer structure is provided and has the characteristics of being remarkable in shock reduction effect, stable in working and long in service life.

Description

Technical field: [0001] The invention relates to the technical field of buffers, in particular to a pneumatic damping buffer with remarkable shock absorption effect. Background technique: [0002] The buffer is mainly used to suppress the shock and impact when rebounding. It mainly plays a buffer role, and has less impact to protect other structures in the equipment. A large number of buffers in the prior art are spring-type buffers, which mainly use springs. In the process of compression, the principle of shock absorption can be used to play a buffering role. The main purpose of the spring buffer: shock absorption and isolation of fans, wind cabinets, air conditioning boxes, air compressors, air conditioning units, generators, cooling towers and other equipment Vibration, if it can be additionally equipped with a damper, it can be applied to the vibration isolation of impact equipment such as punch presses, pressure machines, and forging hammer machines. The disadvantages ...
