Description
Technical field
The invention patent relates to a kind of starters of engine, specifically, being a kind of rising with waterproof sealing structure
Motivation.
Background technique
In the structure of existing starter, as shown in Figure 1, being to be determined between Driving terminal 2, stator 12 using damping block 8
Position, it to be by opening between electromagnetic switch 10 and Driving terminal 2 that it acts as the sealings guaranteed between Driving terminal 2 and stator 12
It closes sealing ring 9 to be sealed, to guarantee the protective of complete machine, damping block 8 and switch seal ring 9 are two individual components.
Specifically combining Fig. 2 and Fig. 3, Fig. 1 is the starter cross-sectional view of the prior art, and Fig. 2 is the installation signal of the damping block 8 of the prior art
Figure, Fig. 3 are 9 schematic view of the mounting position of switch seal ring of electromagnetic switch 10.Starter as shown in Figure 1, including driving gear
1, Driving terminal 2, isolator 3, drive shaft 4, shift fork 5, seat 6 of shipping and reselling on another market, steel bowl 7, damping block 8, switch seal ring 9, electromagnetic switch
10, planetary gear speed reducing mechanism 11, stator 12, armature 13, brush cover 14 etc., when control system issues start signal, electromagnetic switch
It drives shift fork 5 to get isolator 3 and driving gear 1 forward after 10 energizations, is engaged with engine ring gear and realize engine point
Fire starts.
As shown in Fig. 2, 8 front end of damping block of the prior art be steel bowl 7, steel bowl 7 is pressed in ship and resell on another market seat 6 after play the role of positioning,
Damping block 8 is mounted in the open slot 101 of Driving terminal 2.The wherein open slot of the mounting surface 8a of damping block 8 and Driving terminal 2
101a at 101 contacts face contact, and the circular arc mounting surface 8b of damping block 8 is contacted with the arc contact surface 101b of Driving terminal 2, from
And guarantee the sealing of Driving terminal 2 Yu 12 junction of stator.The position shape that Driving terminal 2, stator 12 are contacted with damping block 8 compared with
The effect of complexity, sealing is poor, and external wet gas and water etc. is easily entered inside starter by this position, is caused in starter
The corrosion of portion's part, then causes defective starter.Simultaneously as damping block 8 is exposed part, with the temperature of external environment, wet
Degree etc. influences, and damping block 8 can occur to soften or crack, and causes 7 position of steel bowl to move back, the main contacts of electromagnetic switch 10 is caused to shift to an earlier date
Cause starter mill teeth failure after connection.
The switch seal ring 9 of electromagnetic switch 10 as shown in Figure 3, is mounted on the O-ring mounting groove 102 of 10 front end of electromagnetic switch
In after reassemble in complete machine.After installation, switch seal ring 9 is understood and is bonded at the contact surface 8c of damping block 8, due to damping block 8
It is rubber parts with switch seal ring 9, since by external environment and impurity effect, contact surface easily softens in use process
Modification is so as to cause seal failure.Neglected loading also easily occurs for Simultaneous Switching sealing ring 9.
In view of above, the waterproof protective grade for how improving starter becomes one of urgent problem in the industry.
