Abstract
The utility model provides a kind of start-stop motor decelerating mechanism sealing device.Described armature shaft is equipped with metal sealing lining, dividing plate mesopore is equipped with rubber sealing boot, armature is through the rubber sealing boot on dividing plate mesopore.The rubber sealing boot of this device can pass through mould one-shot forming, and the interference fit of metal sealing lining is fitted on armature shaft mill teeth changeover portion; Eliminate original gap, effectively realize the sealing to motor decelerating mechanism.
Description
Technical field
The utility model relates to mechanical field, is related specifically to a kind of start-stop motor decelerating mechanism sealing device.
Background technology
The raising that requires armature shaft profile accuracy of start-stop motor now, armature shaft tooth Profile Machining mode switches to Milling Process by original cold extrusion.Because armature shaft is to having certain length mill teeth changeover portion, make there is comparatively wide arc gap between dividing plate mesopore and armature shaft.Because start-stop motor environment for use is severe, add power up brush and constantly wear and tear and become powder, these impurity are entered in reducing gear by the gap between dividing plate mesopore and armature shaft, and cause adverse effect to motor performance.When reducing gear impurity reaches some, motor likely produce abnormal sound, hydraulic performance decline even produce cannot the consequence of car.
Summary of the invention
The purpose of this utility model is to provide one to utilize dividing plate, sealing shroud and metal sealing lining, to the start-stop motor decelerating mechanism sealing device that armature shaft seals.
For achieving the above object, the technical solution of the utility model is:
A kind of start-stop motor decelerating mechanism sealing device, comprise armature shaft, rubber sealing boot, dividing plate, metal sealing lining, described armature shaft is equipped with metal sealing lining, dividing plate mesopore is equipped with rubber sealing boot, armature is through the rubber sealing boot on dividing plate mesopore.
Good effect of the present utility model is:
1, this device eliminates original gap, effectively realizes the sealing to motor decelerating mechanism;
2, the rubber sealing boot of this device can pass through mould one-shot forming, and the interference fit of metal sealing lining is fitted on armature shaft mill teeth changeover portion;
3, this device is easy to hand assembled, durable in use.
Accompanying drawing explanation
Fig. 1, start-stop motor decelerating mechanism schematic diagram of sealing device.
Embodiment
Embodiment of the present utility model is further illustrated below in conjunction with accompanying drawing 1.
See Fig. 1, with interference fit, metal sealing lining 4 is fitted on the mill teeth changeover portion of armature shaft 1 by press, subsequently, this armature shaft 1 assembly is dressed up rotor assembly.Rubber sealing boot 2 is loaded dividing plate 3, and on the reducing gear that this module cover has been assembled on streamline (schematic diagram does not represent), then will complete rotor assembly before through baffle assembly, and insert the supported hole of reducing gear.
