Given an arithmetic sequence $\{a_{n}\}$ with a positive common difference, and $a_{1}=1$. If $a_{2}$, $a_{6}-2a_{1}$, $a_{14}$ are the first three terms of a geometric sequence $\{b_{n}\}$.<br/>$(1)$ Find the general formulas for sequences $\{a_{n}\}$ and $\{b_{n}\}$;<br/>$(2)$ Find the sum $S_{n}$ of the first $n$ terms of the sequence $\{\frac{1}{{a}_{n}{a}_{n+1}}\}$.
