The quantity for holding 3 be it is individual, and respectively positioned at 1 both sides of outer ring location division 11 inner side at, the outside of location division 11 is provided with annulus
Shape or discoid support member 4, in the same old way, the quantity of support member 4 is also two, is correspondingly arranged with bearing 3.
The material of support member 4 is aluminium alloy, on the one hand ensure that supporting role of the support member 4 to sealing ring 5, the opposing party
Face so that the lighter in weight of support member 4, so that the movement of support member 4 is more smoothly.
Sealing ring 5, the material selection politef of sealing ring 5 are provided between the inner ring of support member 4 and bearing 3 so that
The self-lubricating property of sealing ring 5 preferably, also so that sealing ring 5 is preferable to sealing effectiveness that 3 inner ring of bearing is played.It is square as an alternative
Case, the material of sealing ring 5 is rubber.
There is between location division 11 and support member 4 magnetic force and support member 4 has becoming near bearing 3 in the presence of magnetic force
Gesture.Specifically, the material of location division 11 is magnetic material, and in the present embodiment, the material of location division 11 is steel.Or, positioning
It is steel with the material of 7 position corresponding position of Magnet in portion 11.There is on support member 4 multiple Magnet 7 being circularly and evenly distributed, Magnet
7 position is corresponding with location division 11, and Magnet 7 is fixed on the support 4 by glue.Multiple Magnet 7 are uniformly distributed so that support
The movement of part 4 is more stable smooth.Alternatively, multiple being circularly and evenly distributed is fixed with location division 11
Magnet 7, the material of support member 4 is steel.Or, it is steel or Magnet 7 with the material of 7 correspondence position of Magnet on support member 4.
There is on location division 11 screw 6, screw 6 is resisted against on the outer ring 1 of bearing 3.The quantity of screw 6 is multiple and in circle
Week is uniformly distributed.In reducing gear, as screw 6 is resisted against on 3 outer ring 1 of bearing, screw 6 serves elimination dress to bearing 3
Effect with tolerance, so that the structure of reducing gear is more stable.
As shown in Fig. 2 have resigning chamber 41 on support member 4,6 part of screw be located in resigning chamber 41 and resigning chamber 41 chi
The very little external diameter more than screw 6.Screw 6 at least plays position-limiting action in resigning chamber 41 so that 4 opposed fixed member circumference of support member
Positioning.Screw 6 can also play certain guide effect so that the movement of support member 4 is more stable.Therefore, in this reducing gear
In, 6 one side of screw serves the problem for eliminating reducing gear build-up tolerance, and on the other hand, screw 6 is also played to support member 4
Position-limiting action.
Have on support member 4 in circular boss 42, boss 42 is located between sealing ring 5 and location division 11, boss 42
Mutually recline with location division 11.Guide effect is played in movement of the abutment face between location division 11 and boss 42 to support member 4 so that
The moving process of support member 4 is relatively stable smooth.Abutment face between location division 11 and boss 42 also forms certain sealing, and
And, the flatness requirement of the abutment face mutually reclined with location division 11 on boss 42 is higher, and boss 42 is easier accurate compared with sealing ring 5
Processing.Sealing ring 5 is fixed at boss 42 by glue so that the structure of sealing ring 5 is relatively stable.
In the joint running of mechanical hand, interior axle 2 is relatively rotated with outer ring 1, bearing 3 rise between support and
Interconnection function.Support member 4 plays a supportive role to sealing ring 5 so that the structure of sealing ring 5 is relatively stable.Run in reducing gear
During, with the trend to outward leakage, sealing ring 5 is in the contact with 3 inner ring of bearing of sealing ring 5 for the lubricating oil in reducing gear
Play sealing function in place.Between location division 11 and support member 4 during the meaning with magnetic force, location division 11 is with support member 4 wherein
One has Magnet 7, and another also has Magnet 7 or the permeability magnetic material corresponding with Magnet 7, and the two can attract each other.
In this reducing gear, as support member 4 has the trend near location division 11 so that ran in reducing gear
Cheng Zhong, even if sealing ring 5 produces abrasion, support member 4 can make sealing ring 5 behind location division 11, again on 3 inner ring of bearing again
Sealing function is played, so that the sealing effectiveness of reducing gear is preferable.
