Description
図1は、本実施の形態に係る減速機付DCモータ100を出力軸側から見た正面図である。なお、図1は、後述するウォームとウォームホイールとの噛み合い部が見えるように、筐体の一部が切り欠かれた状態を示している。
P=π×m・・・式(5)
Sjo=p/2+m×Xh・・・式(6)
hf=m×hfc・・・式(7)
X=hf×tanα・・・式(8)
P=Sjo+X+H+X・・・式(9)
したがって、凹部の幅Hは、式(8)、式(9)より、
H=P−Sjo−2X=P−Sjo−2hf×tanα・・・式(10)で表される。
G=H/(2tan(θ/2))・・・式(11)で表される。
S=(G×H)/2
=(m2/(4tan(θ/2)))×(π/2−Xh−2hfc・tanα)2・・・式(12)で表される。
この式(12)により、各実施例、各比較例のグリス溜まりの面積Sを算出した。
