Helical Gear Reducers

Helical Gear Reducers Introductions
When motorized worm gear screw jacks or screw jack lifting systems required low travel speed, but screw jacks is can not be reached with 4pole or 6pole 3-phase motor, under this conditions, it will be need 3-phase motor combined with gear reducer. JACTON uses high efficiency and high torque helical gear reducers for motorized worm gear screw jacks or screw jack lifting systems such as sluice gate hoisting systems, stage lifting tables etc. Helical gear reducer is split into horizontal type foot-mounted gear reducer and vertical type flange-mounted gear reducer. Below charts are only show ≤ 3.75kw power helical gear reducer. Larger than 3.75kw power helical gear reducer, please consult JACTON.
 
Helical gear reducer features such as helical gears are made of high-quality alloy steel, are treated with surface hardening and gear ground, Full set ≤ 3.75kw power helical gear reducer are small in volume, with great load-carrying capacity, steady running, low noise and high efficiency.

Helical Gear Reducers Sample Part Number
Sample Part Number:  GRH  -  22  -  400  -  5   - S  -  B
                                         1          2         3      4      5     6

1. Mounting Types
* GRH: Horizontal type, foot-mounted.
* GRV: Vertical type, flange-mounted.
2. Output Shafts Diameter (mm)
* 22: Output shafts diameter 22mm.
* Check below charts with output shafts diameter.
3. Power (w)
* 400: 400w
* Following load capacity, travel speed and service conditions to calculate the power.
* Calculating following Calculation Formulas pages of Technical Supports.
4. Reduction ratio
* 5: Reduction ratio 5:1, example 4 pole motor 1500rpm with 5:1 ratio, output speed 300rpm.
* Check below charts to select gear reduction ratios.
* Note: If you can not find the helical gear reducer  required ratios and dimension with below charts, please consult JACTON.
5. Service Voltage
* S: Single phase, only for 220V, max. 0.75kw.
* T: 3-phases, 380V, available for all power.
* V: 3-phases, available oversea countries voltage, available for all power.
Note: For V, service 3-phases voltage must be marked in your order documents, otherwises, will use 3-phases 380V as the standard.
6. B: Brake
* When vibrating load is exact existence, for all screw jacks or lifting systems, additional brake is necessory.
* For all jtb seriesl ball screw jacks or lifting systems, additional brake is necessory.
* Without brake, no need mark.
