Description

Technical Field

[0001] The utility model relates to the technical field of automotive starters, in particular to a reduction mechanism and an automotive starter. Background Technique

[0002] As is well known, the starting of an engine requires the support of external force, and the automotive starter plays this role. Generally speaking, the starter uses three components to achieve the entire starting process. The DC motor introduces the current from the battery and makes the drive gear of the starter generate mechanical motion. The transmission mechanism meshes the drive gear into the flywheel ring gear and can automatically disengage after the engine starts. The on-off of the starter circuit is controlled by an electromagnetic switch; before the engine runs with its own power, it must be rotated by external force. The process of the engine transitioning from a stationary state to self-running with the help of external force is called the starting of the engine. The common starting methods of the engine are manual starting, auxiliary gasoline engine starting, and electric starting. Manual starting uses the methods of rope pulling or hand cranking, which is simple but inconvenient, and has a large labor intensity. It is only suitable for some small-power engines and is only reserved as a backup method on some vehicles; auxiliary gasoline engine starting is mainly used on large-power diesel engines; the electric starting method is easy to operate, starts quickly, has the ability of repeated starting, and can be controlled remotely, so it is widely used in modern automobiles.

[0003] In the above-mentioned solution and the prior art, when the reduction mechanism in the automotive starter is operating, the gears in the reduction mechanism will be deformed and fractured due to high-speed rotation, which will affect the working state of the drive gear during its use and the service life of the drive gear, and cannot meet the actual use requirements.

Specific embodiments

[0019] In order to clearly and completely describe the purpose, technical solutions of the present utility model, and make the advantages more clear, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model.

[0020] Please refer to Figures 1 to 4 , the present utility model provides two technical solutions:

[0021] Embodiment 1: A reduction mechanism includes a reduction shaft disc 1, a connecting hole 2, and a reduction auxiliary component. Connecting holes 2 are equidistantly and fixedly arranged at one end of the reduction shaft disc 1. The reduction auxiliary component is arranged on the reduction shaft disc 1, and the arranged reduction auxiliary component provides reduction protection for the reduction mechanism in an automobile engine.

[0022] Through the provided reduction mechanism, after the magnetic field winding is energized, at this time, the armature is affected by the electromagnetic field and rotates at a high speed within the magnetic field winding. At this time, the gear one 5 fixedly connected to the armature through the rotating shaft one 8 can rotate with the armature, and the gear one 5 can drive the four gear two 6 to rotate within the internal gear ring 3. At this time, the reduction shaft 15 can rotate synchronously with the gear two 6 and can drive the transmission shaft to rotate. And because the diameter of the gear one 5 is smaller than the diameter of the gear two 6, the gear one 5 needs to rotate several circles to drive the gear two 6 to rotate one circle. Therefore, the rotation speed of the reduction shaft 15 is less than the rotation speed of the armature, which can make the driving gear rotate at a smaller speed and can prevent the driving gear from being damaged, which is beneficial to the long-term use of the driving gear.
