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

Embodiment 1

[0017] Such as figure 1 As shown, an energy storage spring rack and pinion double-rod shock absorber includes two guide shafts 1, two guide sleeve plates 2 sleeved on the guide shafts 1, and teeth are arranged on the opposite surfaces of the two guide shafts 1. The bar 7 is provided with a gear 8 meshing with the two racks between the two racks 7, the gear shaft is installed in the gear seat 9 through the bearing, and the gear seat 9 is sleeved on the two guide shafts 1, and the gear seat 9 The scroll springs 3 are installed symmetrically on the gear shafts 10 on both sides. One end of the scroll springs 3 is fixed on the guide sleeve plate 2, and the other end is fixed on the gear shaft 10. The two connecting sleeves 4 are respectively installed on two different guide shafts 1 At one end of the side, two lock nuts 5 are installed on the corresponding other ends of the two guide shafts 1 .

[0018] When the connecting sleeve 4 transmits the force to the two guide shafts 1, th...

Embodiment 2

[0021] As an optimized design of Example 1, several hooks 6 are provided on the opposite surfaces of the two guide plates 2 , and one end of the scroll spring 3 is fixed on the hooks 6 of the guide plates 2 .

[0022] The symmetrical installation of the scroll springs 3 means that the number of scroll springs 3 on both sides of the gear seat 9 is the same. There are two preferred installation methods:

[0023] 1. One end of two symmetrically installed scroll springs 3 is fixed on two symmetrical hooks of the same guide plate, but there must be one end of another symmetrically installed two scroll springs fixed on another guide plate on two symmetrical hooks.

[0024] 2. One end of the two symmetrically installed scroll springs 3 is respectively fixed on the two hooks of the two guide plates, but one end of the adjacent scroll spring must be fixed on the hook of the other guide plate .

[0025] The gear seat 9 is socketed between the two guide shafts 1 .

[0026] The instal...

Abstract

The invention discloses an energy storage spring rack and pinion double-rod shock absorber. The absorber comprises two guide shafts and two guide sleeve plates which are connected to the guide shaftsin a sleeve mode, racks are arranged on the opposite surfaces of the two guide shafts, a pinion meshing with the two racks are arranged between the two racks, pinion shafts are installed in a pinion seat through bearings, the pinion seat is connected to the two guide shafts in a sleeve mode, volute spiral springs are symmetrically installed on the pinion shafts on the two sides of the pinion seat,one ends of the volute spiral springs are fixed on the guide sleeve plates, the other ends of the volute spiral springs are fixed on the pinion shafts, two connecting shaft sleeves are installed at one ends of the different sides of the two guide shafts correspondingly, and two locking nuts are installed at the other ends of the two guide shafts correspondingly. According to the shock absorber, the plurality of volute spiral springs which are symmetrically installed are matched with the pinion and the racks to absorb shock, shock absorption is fast, rebounding is soft, the reciprocating motion is little, and the damping effect is good; and a guide rod is combined with the guide sleeve plates, the service life depends on the volute spiral springs, and the service life of the shock absorberis greatly prolonged through usage of the volute spiral springs.

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...
