The JDLB series precision dual lead worm gear reducer has six sizes: 45, 50, 55, 63, 75, 90. The left and right tooth flanks of the worm have different lead angles resulting in a gradual change in the thickness of the teeth so that the adjustment of the meshing gap is possible by moving the worm

-The worm gear backlash can be adjusted to less than 1 arc minute

-The meshing gap can be readjusted after the reducer is used

-The shaft coupling is used for the input: reliable and no backlash

-The tapered clamping ring coupling is used for output: reliable and backlash-free

Servo worm gear units have six types 45 - 50 - 55 - 63 - 75 — 90 ,with dual lead womi drive Left and nght flank of worm shaft using different lead angle causing tooth thickness gradual changeSo that you can move worm shaft and adjust backlash。

-Worm gear gyration backlash can be adjusted to less than 1 arc。

-Reducer can be re-adjusted the gap after using。

-Inpul with coupling reliable without backlash。

-Output using conical clamping nng couplings: reliable without backlash。

Output Torque

1.1 Rated Torque

The value is obtained when the torque acts on the smoothly running reducer and the working coefficient (fs) is equal to 1.

1.2 Actual Torque

Based on the actual needs, this value may be equal to or less than the rated torque (Mn2) of the reducer.

1.3 Torque Calculation

The Calculation of the formula below requires the actual torque(Mr2) and the working coefficient(fs). It is useful when selecting the reducer model.

Power

2.1 Rated Input Power

The power (kW) of the reducer in safe operation is listed in the parameter table. They are obtained when the speed is equal to n1, and the working coefficient (fs) is equal to 1.

2.2 Rated Output Power

The formula below can be used to calculate the output power of the reducer

Working Coefficient
