An energy-storing spring-pinion-rack double-rod shock absorber

Abstract

The invention discloses an energy storage spring gear rack double-rod shock absorber, which comprises two guide shafts, two guide sleeve plates sleeved on the guide shafts, racks are arranged on the opposite surfaces of the two guide shafts, and A gear meshing with the two racks is set between the two racks, the gear shaft is installed in the gear seat through the bearing, the gear seat is sleeved on the two guide shafts, and the scroll springs are symmetrically installed on the gear shafts on both sides of the gear seat , one end of the scroll spring is fixed on the guide sleeve plate, the other end is fixed on the gear shaft, the two connecting sleeves are respectively installed on the ends of the two guide shafts on different sides, and the two lock nuts are installed on the corresponding ends of the two guide shafts. the other end. The present invention cooperates with a number of scroll springs installed symmetrically to absorb shock and absorb vibration quickly, but rebounds softly, has less reciprocating motion, and has good shock absorption effect; the guide rod is combined with the guide sleeve plate, and the service life depends on the scroll Spring, and the use of multiple scroll springs greatly prolongs the life of the shock absorber.

Description

technical field [0001] The invention relates to a spring shock absorber, in particular to an energy-storing spring-pinion-rack double-rod shock absorber. Background technique [0002] The spring shock absorber absorbs shock through the spring and is often used to control the continuous fluid vibration disturbance. The shock absorption of the spring can filter the vibration, but the spring itself will reciprocate, causing the spring to be fatigued and damaged. In order to absorb the excess vibration caused by the reciprocating movement of the spring, the existing technology uses a hydraulic rod to absorb it, and the life of the hydraulic rod and the spring Different, causing the service life of the entire shock absorber to be equal to the service life of the damaged object in advance. [0003] Therefore, after the existing spring shock absorber is damaged, the entire shock absorber needs to be removed, replaced or repaired (mainly replaced with a new one), which brings about...

AI Technical Summary

Problems solved by technology

The shock absorbing spring can filter the vibration, but the spring itself will reciprocate, causing the spring to be fatigued and damaged. In order to absorb the excess vibration caused by the reciprocating movement of the spring, the existing technology uses a hydraulic rod to absorb it, and the life of the hydraulic rod and the spring different, resulting in the service life of the entire shock absorber being equal to the service life of the prematurely damaged item

[0003] Therefore, after the existing spring shock absorber is damaged, the entire shock absorber needs to be removed, replaced or repaired (mainly replaced with a new one), which brings about the disassembly of the equipment. If it is carried out in an assembly environment, it will cause invisible damage to the equipment, and it will take a long time to disassemble and install; because one of the hydraulic rods or springs is damaged, replacing the damaged one with a new one cannot achieve a new one. The service life of the shock absorber is very small, so there is very little maintenance, and when it is directly replaced, one of the items is still good, which brings a huge waste of resources
