Is it to reduce stress concentration or something? Can you make it as detailed as possible? Thank you, nice guy!
The opening of the big gear is to reduce and reduce the mass of the big gear itself, and to reduce the moment of inertia of the big gear in operation,To improve the stability of gear pair in the work slowdown, and to reduce the impact of inertia.
Mainly weight loss, but the opening must be evenly arranged, otherwise there will be uneven running problems.
1: lose weight2: expansion and contraction3: easy to pull and take the gear down.
1, save materials and reduce costs;2, reduce gear weight, reduce consumption;3, there may be some special needs, such as opening keyway, etc..Principle: 1, evenly distributed; 2, keyway should only have one.
