Engineering Limiting the torque and safety torque elements

AI Thread Summary
The discussion focuses on identifying components of various safety clutches, specifically seeking clarification on element number 14. Participants confirm that the input and output shafts play crucial roles in power transmission, with friction disks and surfaces facilitating torque transfer. The necessity of splines is debated, highlighting their function in maintaining angular position and preventing rotation between connected parts. The conversation concludes with the identification of key slots as a potential solution for torque transfer, emphasizing the importance of these elements in mechanical design. Overall, the thread provides insights into the mechanics of clutches and the significance of proper component identification.

safety clutches
Greetings
I need to identify the elements of the following safety cluches: we have three different clutches.
I lready identified most of them exept for number 14

Any help would be appreciated !
thank you!
1- output shaft
2-friction surface
3-preloaded spring
4-nut
5- input shaft

6- output shaft
7- input shaft
8-ogival seat
9-sphere
10-preloaded spring
11-nut
12-input shaft
13-output shaft
15-pin

is it a spline?

thank you!
 
1 seems not to be a shaft.
15 has a special characteristic.
Could 12 and 13 be either?

How are 5 and 7 transferring power to their mechanisms?
It should be the same for 14.
No spline seems to be represented.
 
thank you
5 is the input shaft
1 is the output shaft
on 1 there is a friction disk mounted (not repesented) so there is a friction between the friction disk and the friction surface
the friction surface is connected to the input shaft through a housing which transfer power.for the the middle picture
the input shaft 7 is connected to the preolad spring and the sphere. there is a friction between the sphere and an the ogival seat. the ogival seat is on the output shaft, so this is how the torque is transmitted.

No, no, before all that happens. :smile:
Why are splines needed?

I´m just guessing here,
maybe we need to connect the input shaft to another mechanisam and the spline gives a good way for it?

Perfect!
The part inmediately connected to the shaft needs to have a way to avoid rotating respect to the shaft.
Sometimes, both must keep a specific angular position respect to each other.
Again, we don’t have a spline here.

so no idea about this strange line?

can this be a key slot?
