Overview

Gas springs are labor-saving and adjustable springs, which can be divided into self-locking gas springs (such as the bottom lifting of seats, the backrest of boss chairs, etc.) and non self-locking gas springs (such as the lifting support of car trunk and closet doors). The structure of gas springs mainly consists of sleeves, pistons, and piston rods. High pressure air or high-pressure nitrogen gas is added to the sleeve. Due to the unequal area at both ends of the piston, a pressure difference is generated, which pushes the piston and piston rod to move and support people or heavy objects. $r $n Xierko Quick Quotation DICTATOR Brand B-D Series Gas Springs

Product Details

Gas spring is an industrial accessory that can provide support, cushioning, braking, height adjustment, and angle adjustment functions. It consists of the following parts: pressure cylinder, piston rod, piston, sealing guide sleeve, filling material（noble gasOr a mixture of oil and gas, control components inside and outside the cylinder (referring to controllable gas springs) and joints, etc. The principle is to fill an inert gas or mixture of oil and gas into a closed pressure cylinder, so that the pressure inside the chamber is several times or tens of times higher than atmospheric pressure, using the piston rodcross-sectional areaThe pressure difference generated by being smaller than the cross-sectional area of the piston is used to achieve the movement of the piston rod. Due to fundamental differences in principle, gas springs have significant advantages over ordinary springs: relatively slow speed, minimal dynamic force changes (generally within 1:1.2), and easy control.

The disadvantage is that there is no relative volumehelical springSmall, high cost, relatively short lifespan. Unlike mechanical springs, gas springs have an almost linear elastic curve. The elastic coefficient X of standard gas springs is between 1.2 and 1.4, and other parameters can be flexibly defined according to requirements and working conditions.

There are four types of joints for compression type gas springs: single piece, single ear, double ear, and universal ball head, which are respectively single piece, single ear, double ear, and universal ball head. When designing, the matching joint type should be selected based on the specific installation location and the specifications of the gas spring. It is recommended to use the universal ball joint type, which can automatically adjust the connection angle during operation, thereby eliminating the lateral force during the operation of the gas spring. It is particularly suitable for situations that require high installation accuracy. If the installation space is limited, a single ear type can be used. This type of gas spring has a simple structure and requires less installation space. However, it cannot eliminate the lateral force caused by different axes during operation. Therefore, it is necessary to separately design the gas spring pin shaft to connect it. In short, regardless of the type of joint selected, it is necessary to ensure that the door (cover) opens and closes smoothly without interference or jamming after the installation of the gas spring.

Gas spring is a component that can achieve functions such as support, buffering, braking, height and angle adjustment. It is mainly used in construction machinery, such as covers and doors.

Gas springs are mainly composed of piston rods, pistons, sealing guide sleeves, fillers, pressure cylinders, and joints, among which the pressure cylinder is a closed chamber filled withnoble gasOr a mixture of oil and gas, where the pressure inside the chamber is several times or tens of times that of atmospheric pressure. When the gas spring acts, it utilizes the pressure difference between the two sides of the piston to achieve the movement of the piston rod. There are different structures and types of gas springs to meet different usage needs. Compression type gas springs are mainly used in construction machinery, which mainly provide support and have only the shortest and longest working positions. They cannot stop on their own during the stroke
