Committee A01 has identi?

This specification covers normalized and tempered carbon steel, and liquid quenched and tempered alloy steel forgings for pinions, gears, and shafts for reduction gears. Brinell hardness tests shall be made on prepared areas on the forgings after machining to the sizes ordered by the purchaser and after stress relieving if stress relieving is required. Now note the correlation between chemistries in Table 1 of each spec.

Is there any violation in designing a ring forge as per ? The purchaser may indicate the desired location of such identi?

The last thing you want is to have a ring gear fail in service because you decided to cut cost. This is merely a shortcut or guide; you still need to do the calculations to confirm. Posting Guidelines Promoting, asrm, recruiting, coursework and thesis posting is forbidden.
