As shown in Figures 1 to 3, a kind of deceleration coupling, including externality shaft 1, internal gear 2 and axle sleeve 3；Externality shaft 1
Gear part is meshed with internal gear 2, the rotation setting of axle sleeve 3, and internal gear 2 connect with axle sleeve 3 and can be with respect to axle sleeve 3 in certain model
It is moved radially in enclosing.
When installation, externality shaft 1 and axle sleeve 3 are separately connected corresponding component and establish power transmission relationship, at this point, due to outer
The number of teeth of the gear part of tooth shaft set 1 is less than the number of teeth of internal gear 2, while internal gear 2 can be with respect to the diameter in a certain range of axle sleeve 3
To movement, therefore have slowing down power(SDP) while, can also realize radial compensation, play the role of shaft coupling and retarder.So
One, the purpose of deceleration torque increase just can be realized without re-replacing retarder, due to having shaft coupling function, the deceleration
The installation of shaft coupling is simpler, improves replacement efficiency.
Specifically, the end of axle sleeve 3 is provided with the flange with several connecting holes, and internal gear 2 is provided with several through-holes, method
It is blue to be connected by passing through connecting hole with the bolt 18 of corresponding through-hole with internal gear 2, interlayer, spiral shell are formed between bolt 18 and through-hole
The end attaching nut of bolt 18 is provided with gasket on the inside of the inner portion and nut of bolt 18.Further, in interlayer
It is provided with several elastic components 19 being set on 18 periphery of bolt.
In order to further increase torque magnitude, deceleration coupling further includes external tooth wheel shaft 4 and internal tooth axle sleeve 5；Internal tooth axle sleeve 5
Rotation setting is simultaneously coaxial with externality shaft 1, and the axle portion of external tooth wheel shaft 4 is antitorque to be connected in axle sleeve 3, gear part and internal tooth axle sleeve
5 gear part is meshed.The number of teeth of the gear part of external tooth wheel shaft 4 is less than the number of teeth of the gear part of internal tooth axle sleeve 5, therefore can be into
One step increases torque, improves driving power.
