Product Features

KH serial products can be applied to precision positioning or reciprocating motion device and
can output power stably to automated equipment which is operating in minimum vibratility.
Such as printing industry, pipe bender, spring machine industry, LCD inspection equipment,
machine tools, connected ball screw transmission mechanism… and so on.

KH series also recommended to customers who need high precise and durable products.

 

kh applications

Backlash: L1--> 3~5 arcmin; L2--> 5~8 arcmin
Nominal output torque: 13~1200 N-M
Output Power: 0.1~11 KW

Reducer Ratio with 1-Stage (L1) = 1st Stage Gear Ratio
Reducer Ratio with 2-Stage (L2) = 1st Stage Gear Ratio x 2nd Stage Gear Ratio
Reducer Ratio with 3-Stage (L3) = 1st Stage Gear Ratio x 2nd Stage Gear Ratio x
3rd Stage Gear Ratio
ex. : 1-Stage (L1) Reducer Ratio 5:1 = 1st Stage Gear Ratio 5 = 5
ex. : 2-Stage (L2) Reducer Ratio 50:1 = 1st Stage Gear Ratio 5 x 2nd Stage
Gear Ratio 10 = 50
ex. : 3-Stage (L3) Reducer Ratio 500:1 = 1st Stage Gear Ratio 5 x 2nd Stage
Gear Ratio 10 x 3rd Stage Gear Ratio 10 = 500
