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
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 original damaged object 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

[0015] A rack-and-pinion auxiliary double-rod pressure shock absorber, comprising two guide shafts 1, two guide sleeve plates 2 sleeved on the guide shafts 1, racks 7 are arranged on the opposite surfaces of the two guide shafts 1, and A gear 8 meshing with the two racks is arranged between the two racks 7, the gear 8 is installed on the gear bracket 9, the gear bracket 9 is sleeved on the two guide shafts 1, and the two connecting sleeves 4 are respectively installed on the two One end on different sides of the guide shaft 1, two locking nuts 5 are installed on the corresponding other ends of the two guide shafts 1, and a number of pressure springs are installed between the guide sleeve plate 2 and the gear bracket 9 on the side close to the connecting shaft sleeve 3. A guide rod 10 is provided at both ends of the gear bracket 9 respectively, and the two guide rods 10 pass through the two guide sleeve plates 2 respectively.

[0016] Using the pressure spring 3, when the conne...

Embodiment 2

[0019] As an optimized design for Example 1, the guide sleeve 2 is provided with several hooks 6 near the side of the connecting sleeve, hook holes are provided on the side of the gear bracket 9 corresponding to the guide sleeve, and one end of the pressure spring 3 is connected to the hook 6. One end is attached to the hook hole.

[0020] Described gear bracket 9 is a square, and a gear fixing shaft for connecting gear 8 is arranged in the middle of the square, and a guide rod 10 is set on the face of the gear bracket 9 towards the connecting bushing side, and the guide rod 10 passes through the guide sleeve The guide hole provided on the board is covered with a spring 11 on the part of the guide rod 10 exposed outside the guide hole. One end of the spring 11 is connected to the guide sleeve plate 2, and the other end is locked by a pressure plate and a bolt.

[0021] The springs 11 are pressure springs and the two springs have the same material and size. The effect of the s...

Abstract

The invention discloses a gear rack assisted double-rod pressure damper comprising two guiding shafts and two guiding sleeve plates connected to the guiding shafts in a sleeving manner. Racks are arranged on the opposite sides of the two guiding shafts, a gear meshed with the two racks is arranged between the racks, the gear is mounted on a gear bracket, the gear bracket is connected to the two guiding shafts in a sleeving manner, two connecting shaft sleeves are mounted at one ends of the different sides of the two guiding shafts, two locking nuts are mounted on the corresponding other ends of the two guiding shafts, a plurality of pressure springs are arranged between the sides, close to the connecting shaft sleeves, of the guiding sleeve plates and the gear bracket, the two ends of thegear bracket are each provided with a guide rod, and the two guide rods pass through the two guide sleeve plates. The gear rack assisted double-rod pressure damper is good in damping effect, replacement is conveniently carried out when the single springs are damaged, and disassembling of the entire damper is not needed.

Description

technical field [0001] The invention relates to a spring shock absorber, in particular to a rack and pinion auxiliary double-rod pressure 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. 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 disa...
