Double Disk Shaft
Double Disk Shaft
Image
Description
Level the load, and increase convenience to assemble by bolt it last.
¡Ø For all drive shafts, it is recommended to use a key to prevent slipping during operation, and when inserting couplings on both keys, the error range is within about 15 degrees.
Therefore, when using a reducer, the 15 degree/reduction ratio becomes the assembly error range for the keys of both shafts
Information

Feature

a Seperation type for coupling and pipe

b Existing ket seat

c Screwed with set screws at the end of the shaft

d Instal polyurethane sleeve

e occur twsting when assemble

Insert two couplings into the shaft at both ends. Complete to assemble by screwed bolts after drilling and tapping.

Feature

  • Work on the assembly site
  • If one axis is required on rotate due to the change in the position of the part receiving the load, it must be reassembled.
  • Materials may need to be changed during production.
  • Able to keep durable.
  • Difficult to machine while mounted.

Feature

a Coupling and pipe with all-in-one design(machining)

b Screwed with using a bolt at the end of the shaft

c Installed polyurethane sleeve
(High torque performence, low misalignment-compared to the outside diameter)

d No keys

e No twisting when assemble

Feature

  • Consume high cost and time
  • No keyway to avoid reassemble.
  • Occur slip due to tolerance if use only clamp excluding keyway.
  • Difficult to machine while mounted.

Simply assmeble in field ¡¤ Avoid damage to the shaft end

Able to assemble in clean room

Remove slip ¡¤ Increase durable

Increase safety

Feature

1 Coupling and pipe with all-in-one design

b Existing keyway

3 Screw bolts at the end of shaft(x2)

4 Install polyurethane sleeve

d occur torsion when assemble

Improvement

Pipe attachment - Save cost and time
Able to supply by removing the clamp : Able to assemble in field by final assmeble without work.

Disadvantage

Able to occured torsion : Twisted stiffiness cannot be avoided when each coupling keyway is inserted into the shaft at both ends.

Description
  • Removed Hub(Length of Bk) and machining keyway is standard spec.
  • Using a material with high stiffiness among polyurethane, the torque performance is very good compared to the outside diameter.

Change the reason of torsion ¡¤ Change the coupling ¡¤ Minimize torsion

Increase efficiency

Feature

a and pipe with all-in-one design

b Existing keyway

3 Screw bolts at the end of shaft(x2)

5 Minimize torsion due to assembled

6 Insert double disk(High misalignment
increase in torque by incresing the outside diameter

Improvement

Minimize torsion

  • Level the load, and increase convenience to assemble by bolt it last.
  • When inserting couplings on both keyways, the torsion error range is within about 15 degrees.
  • When using a reducer, 15 degree/reduction ratio becomes the assembly error range of Load Level.
Additional feature

Increase offcenter and angle of deviation endplay by at least 1.5 to 3 times through assemble two double disk couples.

Double Disk Coupling / Shaft
Image
Description
  • Remove the clamp, fix the reducer shaft with 2 screws, STS material available.
  • Better compensation of both offcenter and angle of deviation, Changable position of keyway
  • Minimize tension during assembly. when applied to a narrow space, the position of the shaft end of the reducer can be arranged between b and c.
  • Double discs can be used on both sides, in which case offcenter and angle of deviation are allowed more than doubled.
