Specific embodiment
Specific embodiment of the present utility model is made into one by the description to optimum embodiment below against attached drawing
Step detailed description.
A kind of starter slowing-down mechanism safeguard structure, safeguard structure include for being connected on armature shaft for avoiding slowing down
The partition of mechanism lubricating grease, partition include partition body 1, and the connecting hole for being connected on armature shaft is equipped on partition body 1,
It is equipped in connecting hole for sealing the sealing ring 2 for preventing deceleration mechanism lubricating grease from throwing away, sealing ring 2 is equipped with for being socketed in
Through-hole 3 on armature shaft；The utility model can be tradition by increasing sealing ring 2, sealing ring 2 on 1 connecting hole of partition body
Elastic rubber ring, such setting to a certain extent optimizes conventional baffle body 1, guarantees connecting hole on partition body 1
With the compactness of armature axis connection, not only may be implemented axially to limit planetary gear, moreover it is possible to prevent lubricating grease in deceleration mechanism
It throws away, avoiding deceleration mechanism lubricating grease from throwing away makes between planetary gear and internal gear cooperation have some setbacks to generate noise.
Preferably, partition body 1 is connected by interconnecting piece with sealing ring 2 in the utility model；Interconnecting piece includes setting
The clamping block 8 on connecting hole inner wall is set, the clamping groove 5 for being connected with clamping block 8 is equipped on 2 lateral surface of sealing ring,
The setting of clamping groove 5 is equipped with clamping block 8 in the outside of sealing ring 2 on connecting hole inner wall, passes through the mutual of clamping block 8 and clamping groove 5
The connection of partition and sealing ring 2 is realized in cooperation, and this connection type is simple, also facilitates the replacement of the two；For stable connection
Property, it can according to need and be equipped with multiple clamping blocks 8 in connecting hole inner wall, be equipped on the outside of sealing ring 2 corresponding with each clamping block 5
The clamping groove 5 of setting；Clamping block 8 is arranged in a ring on connecting hole inner wall in the present invention simultaneously, and clamping groove 5 is close
The outside of seal 2 is also arranged in a ring, and the purpose being arranged in this way is the globality for guaranteeing partition body 1 and connecting with sealing ring 2, can also be with
Increase leakproofness to a certain extent.
Preferably, sealing ring 2 is close to one end of partition body 1 equipped with chamfer bevel 7 in the utility model；Chamfer bevel
7 setting can facilitate the assembly of partition body 1 Yu sealing ring 2 to a certain extent, also facilitate the later period present apparatus and armature shaft with
And other components are connected.
Preferably, internal on the inner wall of through-hole 3 in the utility model be equipped with elastic spoiler；Elastic spoiler includes
