Technical Field

[0001] The utility model relates to the technical field of deceleration starters, in particular to a shock absorbing device for deceleration starters. Background Art

[0002] A starter with a gear reducer installed between the armature shaft and the drive gear is called a reduction starter. The power of a series-excited DC motor is proportional to its torque and speed. When the motor speed is increased while its torque is reduced, the starter power can be kept unchanged. Therefore, when a high-speed, low-torque series-excited DC motor is used as a starter, the volume and mass of the starter can be greatly reduced while the power is the same.

[0003] However, most of the existing reduction starters have poor shock absorption effect during installation and use, and cannot effectively buffer the impact force, which easily causes the reduction starter to be damaged by the impact force. Secondly, most of the existing reduction starters are installed and fixed by bolts, which makes the reduction starter inconvenient to disassemble and assemble, time-consuming and labor-intensive.

The sliding sleeves 17 and the buffer spring 131 cooperate with each other.

[0020] The installation of the shock absorber body 1 is completed through the positioning seat 11 according to the position where the deceleration starter body 4 needs to be installed. The installation and fixation of the deceleration starter body 4 are completed by cooperating with the fixing seat 3 through the two fixing plates 2 installed on both sides of the top surface of the positioning seat 11. The two ends of the connecting rod 15 rotate in the first rotating member 14 and the second rotating member 16. When the deceleration starter body 4 is impacted by external force, the fixing seat 3 on which the deceleration starter body 4 is installed controls the four sliding sleeves 17 to slide on the surfaces of the two sliding rods 13 respectively under the cooperation of the four first rotating members 14, the four connecting rods 15, the four second rotating members 16 and the two buffer springs 131 sleeved on the surfaces of the two sliding rods 13.
