Detailed Description
The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.
As shown in fig. 1 to 5, such a damper gear of the present utility model includes a gear body 1, a driving disk 2, and a damper 3.
A placement hole 4 is arranged in the middle of the gear body 1, and a plurality of mounting notches 5 are arranged on the inner wall of the placement hole 4. The installation notch 5 is provided with limit parts 6 which are symmetrically arranged, and the limit parts 6 are positioned at the joint of the compression part 7 and the extension arm 8. The limiting part 6 can limit the shock absorbing element 3 in the mounting notch 5 better.
The gear body 1 is provided with stepped grooves 9 on two sides, baffle plates 10 are arranged in the stepped grooves 9, and the baffle plates 10 are arranged on the gear body 1 through pin shafts 11. The baffle 10 is provided with a first pin hole 12, the gear body 1 is provided with a second pin hole 13, the pin shafts 11 are arranged in the first pin hole 12 and the second pin hole 13, the baffle 10 is fixed in the stepped groove 9 on the gear body 1, and the driving disc 2 can be limited in the placing hole 4 through the baffle 10.
The driving disc 2 is arranged in the placing hole 4, a shaft hole 14 is arranged in the middle of the driving disc 2, a rotating shaft 15 is arranged in the shaft hole 14, the shaft hole 14 through which the rotating shaft 15 passes is arranged on the baffle plate 10, and the rotating shaft 15 passes through the baffle plate 10 to be connected with the driving disc 2. The diameter of the drive disc 2 is smaller than the inner diameter of the placement hole 4.
The outer wall of the driving disc 2 is provided with a plurality of mounting grooves 16, and damping gaps 17 are formed between the gear body 1 and the driving disc 2.
The shock-absorbing member 3 is disposed in the shock-absorbing gap 17, the middle of the shock-absorbing member 3 is disposed in the mounting notch 5, both ends of the shock-absorbing member are inserted into the mounting grooves 16, and the rotating shaft 15 drives the driving disc 2 to drive the gear body 1 through the shock-absorbing member 3.
The shock-absorbing member 3 is composed of a compression part 7, and extension arms 8, arc-shaped parts 18 and fixing parts 19 which are symmetrically arranged, wherein the compression part 7 is arranged in the mounting notch 5, the extension arms 8 and the arc-shaped parts 18 are positioned in the shock-absorbing gap 17, and the fixing parts 19 are inserted into the mounting grooves 16. The compression portion 7 is in a cross spiral shape. The arc-shaped portion 18 is in contact with the inner wall of the placement hole 4. The middle of the compression portion 7 forms a compression region 20.
Since the extension arms 8 are disposed in a cross-symmetrical manner, the compression portion 7 can withstand external forces of forward rotation and reverse rotation.
A movable gap 21 exists between the inner wall of the mounting notch 5 and the maximum diameter of the compression part 7, so that the compression part 7 can move in the movable gap 21 when being subjected to external force.
When the rotary shaft 15 rotates, damping can be achieved regardless of whether it rotates in the forward direction or in the reverse direction. After the driving disc 2 rotates, the fixing 19 is pushed by the driving disc 2, so that the fixing 19 pushes the extension arm 8, and an external force acts on the compression part 7, so that the compression part 7 of the shock absorber 3 counteracts a part of the external force, and then the compression part 7 acts on the outer wall in the mounting notch 5 to push the gear body 1 to rotate.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
