Geometry of chain wheels |
 Chain wheels can be described
by the following data:
- diameter of the chain (d)
- pitch of the chain (t)
- number of teeth (Z)
- pitch circle diameter (DT)
- outer diameter (D)
- width of the wheel (Bc)
- width of the hub (BN)
- diameter of the hub (DN)
|
| |
The chain wheel is described by:
Z = Number of teeth
S = Ratio
|
| |
For the practical application the
second expression is negligible.
|
| |
| The error when applying the
shortened formula will be less,
the larger the pitch is in relation
to the diameter and the more
teeth the chain wheel has. |
