Model Selection

1. Calculation formula for model selection: (1)PIN=P1Xf(Starts and stops per hour ≤20 times/hour)

(2)PIN=1.2XP1Xf(Starts and stops per hour 21~60 times/hour)

(1)PIN≤PN

The selected power must be less than or equal to the allowable power

Where: PIN is the selection power, P1 is the actual required power, f is the service factor, PN is the allowable power.

Service factor f

Thermal power verification

1. Thermal power calculation: PGN=PGXf1×f2

PGN>P1(Natural cooling)

PGN

Where: f1 is the ambient temperature coefficient, f2 is the continuous operation coefficient, PG is the heat capacity of the reducer, P1 is the actual required working power, PGN is the calculated heat capacity of the reducer.

2. Ambient temperature coefficient f1

3. Continuous operation coefficient f2

Heat capacity PG(Natural cooling)

General technical specifications

1. Key and keyway dimensions comply with GB1095-79 and GB1096-79 standards, keyway width tolerance: shaft N9, hub JS9.

2. Output and input shaft center holes are generally threaded, specifications as follows:

D=11~13mm     Thread M3       D>24~30mm      Thread M10

>13~16mm       Thread M5        >30~38mm      Thread M12

>16~21mm       Thread M6        >38~50mm      Thread M16

>21~24mm       Thread M8        >50~85mm      Thread M20

3. In the outline installation dimension drawing, the input and output shafts, under allowable speed and torque conditions, may allow the output shaft to function as an input shaft for speed-increasing transmission.
