منع انزلاق السيارات على بعد 15 ملم

ما توصّل إليه النقاش

  • A motor can slip off a focus rod when the torque causes the rod to bend away from the lens gear, and bridging the motor host rod to another rod with a 15mm bridge clamp prevents this bending and solves the problem
  • Mounting the motor so its gear engages the lens at the top, bottom, or side position reduces slippage compared to other angles
  • Using a dogbone with independent tightening screws on both ends instead of a single-handle design minimizes slippage
  • Wrapping gaff tape around the rod before clamping the motor increases friction and can prevent slippage
  • A bongo tie around the motor and opposite rail can stabilize the motor against slippage
  • Motor power should not be maximized during operation as it increases the risk of the motor disengaging from the barrel
  • Mounting a rod above the lens with the motor hanging down uses gravity to prevent the motor from jumping away
  • Ensuring cutouts on 19-15mm adapters align with the motor rod clamp cutouts reduces slippage
  • Manual calibration should stop before the lens hard stop rather than at it, as the motor may jump off when hitting the stop

يعتمد على

  • The physics of why gear positioning angle reduces slippage is not fully understood by practitioners
  • Solutions for slippage depend on rod material, with aluminum and carbon fiber being more prone to bending than steel
  • Longer rods increase the likelihood of bending-induced slippage
  • The precision of manufactured components varies considerably and affects slippage problems
