As the Himmel® agitator gear units must withstand high axial and radial forces; they are equipped with a reinforced abrasion shaft and reinforced bearing as standard and therefore offer high operational safety.

Cooling tower gear motors and cooling tower gear units
Cooling tower gear motors are helical gear motors with reinforced axial and radial bearings. They are equipped as standard with a hood over the fan cover providing protection from rain and other weather conditions.
|Power||kW||0,9 to 75|

|Ratio||1,48 to 14,92|
Overhead track gear motors and overhead track gear units
Himmel® electric overhead track gear motors are designed to be modular, perfectly matched to each other and can be extended as required. They are characterized by the highest availability and a largely maintenance-free operation. The gear units are supplied as worm gears, spur and three-stage bevel gears.
They are equipped with a mechanical dog clutch that can be shifted under load. The gear units are suitable for different mounting positions.
The main applications of the electric overhead track geared motors lie in the automotive, food and packaging industries.
|Power||kW||0.045 to 7,5|
|Torque||Nm||6 to 1003|
|Speed||min1 /rpm||3 to 316|
Variable speed belt gear motors and variable speed belt gear units
The variable speed gear unit housing has a proven symmetrical design. The adjusting pulleys have a wedge shaped symmetrical cross section with low mass. The shape of the pulleys ensures uniform flank pressure and therefore high power transmission, even at high belt speed.
The result is optimal control behaviour with uniform distribution of forces and minimal energy consumption.
|Power||kW||0,37 to 160|
|Torque||Nm||1 to 1100|
|Speed||min1/rpm||248 to 3900|
|Adjustment range||1:2,8 to 1:5,5|
Friction gear motors and friction gear units
If the output speed decreases the torque increases – this is the basic principle of the friction gear unit. Unlike inverter operation the motor power remains constant and the torque increases if the output speed of the motor drops. The infinitely variable adjustment of the friction gear unit enables gear reduction ratio as well as gear gain ratios. Friction gear units find their main applications in the textile and food industries.
The power is transmitted through one or two consecutively arranged pairs of friction wheels. The pressing force needed for power transmission is generated by a cam curve depending on the applied load. The pressure required when starting is provided by a compression spring. Actuating the adjusting device causes the effective diameter of the driving and driven cone to change. This results in a change in output speed.

Variable chain drives (FMB-Variatoren®)
If the output speed decreases the torque increases – this is the basic principle HIMMEL® Variable chain drives (FMB-Variatoren®). Unlike inverter operation the motor power remains constant and the torque increases if the speed of the motor drops. For example, ideal for winding drives, accumulating conveyors or conveyor belts.
The positive linkage between chain and gear wheel allows for constant speeds even with torque fluctuations and very good reproducibility of speeds. Standard variable gear units force the transmission element by applying excessive force – this is unnecessary and reduces the degree of efficiency.
HIMMEL® Variable chain drives (FMB-Variatoren®) apply a lever mechanism, which applies only as much pressure on the slat chain as necessary. This results in low operating temperatures, long life, high power density and an excellent efficiency – even in the partial load range.
