Product Features

The F Series parallel shaft gearmotor incorporates the following specified features:

1. Modular Design, Compact Structure. Extra-Slim Parallel Shaft Helical Gearmotors are the Perfect Solution When Space is Limited: The modular architecture enables various configurations from standardized components. The extra-slim parallel shaft design provides space-efficient installation where compact dimensions are required. This configuration proves ideal for applications with restricted mounting space.

2. F Series Parallel Shaft Helical Gearmotors are Typically Used in Conveyors and Materials Processing Applications: The design characteristics suit conveyor drive systems and material processing equipment. The parallel shaft configuration accommodates the mounting requirements common in conveyor and material handling installations.

3. Multi-Stage (2 or 3 Stages) Gear Units for Low Output Speed: Two-stage or three-stage configurations enable low output speed requirements through increased reduction ratios. Multi-stage arrangements achieve greater speed reduction within the parallel shaft housing design.

4. Hollow Output Shaft with Keyed Connection, Shrink Disk, Splined Hollow Shaft, or Torque Arm: Multiple hollow shaft configurations are available including keyed connection (FA Series), shrink disk (FH Series), splined hollow shaft (FV Series), and torque arm variants (FAT Series), addressing diverse mounting and connection requirements.

5. Can be Combined with Other Types of Gearboxes (Such as R Series, UDL Series): The series can be combined with R Series coaxial helical gearboxes and UDL Series stepless variators for expanded drive configuration possibilities. Combination options extend ratio ranges and enable specific output orientations.

6. Optional Mounting Options (Foot-Mounted, Flange-Mounted, Shaft-Mounted): Three mounting methods accommodate different installation requirements. Foot-mounted (F, FAB, FA Series) provides standard base mounting. Flange-mounted (FF, FAF, FAZ Series) enables direct equipment attachment via B5 or B14 flanges. Shaft-mounted (FAT Series) allows hanging installation on driven shafts with torque arm support.

Installation Methods

Foot-Mounted Configuration

Foot-mounted models (F Series, FAB Series, FA Series) feature mounting feet for installation on horizontal surfaces or equipment bases. This configuration provides stable support and accommodates various foundation designs.

B5 Flange-Mounted

B5 flange-mounted variants (FF Series, FAF Series) incorporate B5 standard flange dimensions for direct attachment to equipment flanges or motor brackets. This mounting method eliminates separate foot-mounted base requirements.

B14 Flange-Mounted

B14 flange-mounted configuration (FAZ Series) utilizes B14 standard flange specifications, providing alternative flange mounting option for equipment with B14 flange interfaces.

Shaft-Mounted

Shaft-mounted installation (FAT Series and torque arm configurations) enables direct mounting onto driven equipment shafts. The torque arm assembly absorbs reaction forces, securing the gearmotor position during operation without separate mounting base.

System Integration Capability

Combination with Other Gearbox Types

The F Series design enables combination with additional gearbox types to expand application possibilities:

F + R Series Combination: Connecting F Series parallel shaft units with R Series coaxial helical gearboxes creates combined drive configurations. This arrangement can achieve extended ratio ranges or specific shaft orientation requirements.

F + UDL Series Combination: Integration with UDL Series stepless variators enables variable speed control capability. The combination provides adjustable output speed while maintaining the parallel shaft configuration of the F Series.

These combination options utilize standard interface connections between gearbox types, facilitating system assembly for specialized drive requirements.

Conveyor and Material Processing Applications

The F Series parallel shaft helical gearmotor serves as a typical solution for conveyors and materials processing applications. The extra-slim design accommodates the space constraints common in conveyor installations where mounting depth is limited. The parallel shaft configuration aligns with conveyor drive mounting requirements, simplifying integration into conveyor frames and material handling equipment.

Multiple hollow shaft output options suit various conveyor drum shaft mounting methods. Keyed hollow shaft (FA Series) provides traditional keyway connection. Shrink disk mounting (FH Series) enables keyless installation on conveyor drums. Splined hollow shaft (FV Series) accommodates splined drum shaft designs. Torque arm configuration (FAT Series) supports hanging shaft-mounted installations directly on conveyor rollers.

The modular design with optional mounting arrangements (foot, flange, shaft-mounted) addresses diverse conveyor equipment configurations. Multi-stage gear units deliver the low output speeds required for heavy-duty conveyor applications, while the wide ratio range from 3.81 to 270.16 enables precise speed matching to material transport requirements.

Lubrication and Cooling Systems

Oil-Bath and Splash Lubrication

The gearmotor employs oil-bath and splash lubrication methodology. Gear rotation distributes lubricant throughout the gear chamber, providing continuous lubrication to all meshing surfaces and bearing locations. This passive lubrication system operates without external pumps or circulation equipment.

Natural Cooling Design

Heat dissipation occurs through natural cooling from the cast iron housing surfaces. The housing design facilitates heat transfer from internal components to the external environment through natural convection and radiation, maintaining operational temperatures without forced cooling systems.
