Problems solved by technology
This type of buffer has the following deficiencies: (1) the sealing ring 106 arranged between the piston rod 104 and the sleeve bearing 105 is used for sealing. When the piston rod 104 moves linearly, the oil in the cylinder 101 will always It sticks to the surface of the piston rod 104 and leaks continuously. After a period of use, a vacuum will be formed in the cylinder 101 due to oil leakage, and air inhaled in the cylinder 101 will eventually cause the buffer to be scrapped, so its service life is longer. Short; (2) simply utilizing the partial compression of the liquid and the compressible sleeve 108 arranged between the cylinder 101 and the shell 107 to balance the volume reduction of the piston rod 104 entering the cylinder 101, in order to ensure the effective function of the piston rod 104 stroke, the diameter of the piston rod 104 should not be too large, resulting in poor rigidity of the piston rod 104, which cannot withstand large impact loads, which limits its application field
