GEAR BOX TECHNICAL DATA

Shaft Alignment : The below floor plan is determined according to the installation location and the alignment.

Distance between shafts : It is the reducer’s frame No. and marks the dimension. It is selected by means of the transfer capacity table depending on the usage.

Reduction Ratio

Deceleration	Range of Deceleration Ratio	Nominal Deceleration Ratio	Tolerance
Single-stage Deceleration	1/6.3~1/20	1.25, 1.8, 2.5, 4, 5, 5.6, 6.3	±3%
Second stage Deceleration	1/1.25~1/6.0	7.1, 10, 12.5, 14, 16, 18, 20	±3%
Third stage Deceleration	1/22.4~1/90	22.4, 28, 31.5, 40, 50, 63, 80, 90	±4%
Forth stage Deceleration	1/100~1/450	100, 112, 125, 140, 200, 280, 400, 450	±4%

Gear Box Selection Method : Determine reducers with necessary dimensions according to the following procedure.

1. Determine the Service Factors

2. Equivalent Transfer Capacity

Equivalent Transfer Capacity = Real Transfer Capacity × Service Factor

3. Select Frame

Select the frame that has a larger capacity than that of the equivalent transfer capacity by comparing the equivalent transfer capacity with the rated transfer capacity in terms of the revolutions and deceleration ratio required by the rated transfer capacity table.

Equivalent Transfer Capacity ≤ Real Transfer Capacity

4. Review Heat Capacity

1) Determine the temperature correction factor : Determine the temperature correction factor by comparing the ambient temperature with the temperature correction factor table.

Ambient Temp. ℃	Temperature Correction Factor
	No Fan	Attached Fan
20	1.00	1.00
30	0.85	0.87
40	0.70	0.73
50	0.55	0.60

2) Determine the equivalent heat capacity

Equivalent Heat Capacity = Real Transferred Power ÷ Temperature Correction Factor

3) Check heat capacity : Check the heat capacity based on the rated heat capacity table and
the equivalent heat capacity.

Equivalent Heat Capacity ≤ Rated Heat Capacity

Examples of Selection

1) Specifications

Operation Time	10hours/day
Transferred Power	75kW
Input Revolutions	1200r.p.m
Output Revolutions	38r.p.m
Deceleration Ratio	1/32.57
Driven Motor	Agitafor

2) Use Factor

Operation Time	Light Impact
max 10hours/day	M
	1.25

3) Equivalent Transferred Power

75kW x 1.25 = 93.8kW

4) Select Frame : Because the rate transfer capacity of Size JK-CT700 of deceleration ratio 31.5 is 135kW

93.8kW < 135kW
