Model description, H, B types of gearbox high power reducer

HB series standard industrial gearbox features:

1. H, B types of gearbox high-power gear reducer adopts universal design scheme, which can be changed into industry-specific gearbox according to customer requirements.
2. Realize parallel shaft, orthogonal shaft, vertical and horizontal universal box, reduce the number of parts and components, and increase the number of specifications.
3. Adopting the structure of the suction box body, large cabinet surface area and large fan, cylindrical gear and spiral bevel gear adopt advanced grinding process to improve the temperature rise, noise reduction and reliability of the whole machine. The power is increased.
4. Types of gearbox Input method: motor coupling flange, shaft input.
5. Output mode: solid shaft with flat key, hollow shaft with flat key, hollow shaft with expansion disc, hollow shaft with spline joint, solid shaft with spline joint and solid shaft with flange joint.
6. Installation method: horizontal, vertical, swing base type, torsion arm type.

   
   

H, B types of gearbox products have 3 to 26 specifications, the number of reduction transmission stages is 1 to 4, and the speed ratio is 1.25 to 450; and the combination of R, K and S series of our factory has a larger speed ratio.

1. Technical Parameters:
2. Speed ratio range 1.25-450
3. Torque range 2.6-900kN
4. Power range 4-5000kW

1. Symbol Description

ED = hourly duty cycle, expressed as a percentage, such as ED=60%/h

Fl = driven device factor (Table 1)

F2= prime mover coefficient

F3=bee plant torque coefficient

F4, f5 = ambient temperature coefficient (Tables 2, 3)

F6, f7 altitude coefficient (4, 5)

F8=Gearbox oil supply coefficient (Table 6)

F9, f10, f11, f12 = heat capacity coefficient (Tables 7, 8, 9, 10)

A1 two model coefficients (Table 11)

A2=speed ratio power (Table 12)

P1 = input power

PG1 = gearbox heat capacity without auxiliary cooling release

PG2=The heat capacity of the gearbox with cooling fan unit

PG3 = gearbox heat capacity with built-in cooling coil

PGI = gearbox heat capacity with internal release cooling coil and fan
