Claims (4)
- 樹脂製の一対の歯車を組み合わせて対向する歯の噛み合いにより2軸間に回転運動を伝える歯車装置であって、
一方の歯車の歯の一の歯面側のみにて、その歯幅方向端部の少なくとも一方の端部には、上記一の歯面側から隣の歯側に向かって斜めに張り出して上記一対の歯車の噛み合い時のバックラッシを無くす張り出し部を設け、
他方の歯車の歯の歯幅方向端部にて上記一方の歯車の張り出し部に対応する端部側の端面には、その歯形の内側に該端面から所定深さを有する肉抜き部を設け、
上記一対の歯車の対向する歯の噛み合いにより、一方の歯車の張り出し部が弾性変形すると共に、他方の歯車の肉抜き部も弾性変形してバックラッシ量を吸収するようにし、
前記肉抜き部は、その最深部から前記端面に向かうに従って残り部材を徐々に薄くするように形成されていることを特徴とする樹脂製歯車装置。 - 樹脂製の一対の歯車を組み合わせて対向する歯の噛み合いにより2軸間に回転運動を伝える歯車装置であって、
一方の歯車の歯の両方の歯面側にて、その歯幅方向端部の少なくとも一方の端部には、上記両方の歯面側から隣の歯側に向かって斜めに張り出して上記一対の歯車の噛み合い時のバックラッシを無くす張り出し部を設け、
他方の歯車の歯の歯幅方向端部にて上記一方の歯車の張り出し部に対応する端部側の端面には、その歯形の内側に該端面から所定深さを有する肉抜き部を設け、
上記一対の歯車の対向する歯の噛み合いにより、一方の歯車の張り出し部が弾性変形すると共に、他方の歯車の肉抜き部も弾性変形してバックラッシ量を吸収するようにし、
前記肉抜き部は、その最深部から前記端面に向かうに従って残り部材を徐々に薄くするように形成されていることを特徴とする樹脂製歯車装置。 - 前記一方の歯車の前記歯幅方向端部の少なくとも一方の端部に空洞部を形成し、この空洞部を囲むように薄肉部を形成し、この薄肉部のうち一方の歯面側を隣の歯側に向かって斜めに張り出して前記張り出し部としたことを特徴とする請求項1に記載の樹脂製歯車装置。
- 前記一方の歯車の前記歯幅方向端部の少なくとも一方の端部に空洞部を形成し、この空洞部を囲むように薄肉部を形成し、この薄肉部の両方の歯面側をそれぞれ隣の歯側に向かって斜めに張り出して前記張り出し部としたことを特徴とする請求項2に記載の樹脂製歯車装置。
