S Series Parallel Shaft Helical Gear Units with Large Torque

The S Series Parallel Shaft Helical Gear Units with Large Torque are widely used in various industries such as motor and industry. They feature a cycloidal layout and hardened hardness. These gear units are available for customization according to customers’ requirements.

Technical Features:

– The high degree of modularity allows for easy connection with different types of motors.
– Suitable for various drive fields including textile, foodstuff, ceramics packing, logistics, and plastics.
– Can be set up with flanges or feet as required.

Product Characteristics:

– Ground-hardened helical gears for durability.
– Modular design allows for various combinations.
– Lightweight aluminum casing.
– Gears made from carbonize hard material.
– Universal mounting options.
– Refined design for space efficiency and low noise.

Structure Feature:

The model of the gear units is described by the following codes:
1. Code for gear units series.
2. F code for foot mounted, B5 code for B5 flange mounted, Z code for B14 flange mounted.
3. Specification code of gear units.
4. Output flange specification: I, II, III, B5.
5. Input flange: IEC or HS (shaft input).
6. Transmission ratio of gear units.
7. Mounting position: M1 is the default.
8. Position diagram for motor terminal box: default position is o°(R).
9. Motor model (poles of power): No mark means without a motor.
10. Voltage – frequency.
11. Coil in position for motor: default position is S.

Rotation Speed:

– Gear units input speed (n1).
– Gear units output speed (n2).
– For optimal working conditions and longer service life, it is suggested to have a rotation speed of 1400r/min or lower if driven by external gearing. Higher input rotation speed is permitted, but it may reduce the rated torque.

Service Factor:

The service factor (fs) is determined based on the daily operation time and starting frequency (Z) of the driven machine. Three load classifications are considered, and the suitable service factor can be obtained from the performance parameter table.

Performance Parameter:

– Output speed
– Torque
– Speed ratio
