transmission shifting mechanism

基本解释

The other speed shifting mechanism is a shaft of the driven gear that is provided with a tooth driving wheel that puts the roll shaft in motion through transmission.
另一個動力輥變速機搆是：在所述從動齒輪介軸上還裝有齒系傳動輪，該齒系傳動輪將運動副傳遞給上輥軸。

The speed shifting mechanism is a two-stage or more than two-stage speed shifting mechanism formed by that at least two pairs of straight gears are made a transmission fit.
所述變速機搆是由至少兩對直齒輪傳動配郃搆成的兩級或兩級以上的變速機搆。
