Applications

• Conveyors and material handling
• Fans and pumps
• Mixers and agitators
• Crushers and grinders
• Food and beverage processing
• Packaging equipment
• Textile machinery
• Waste water treatment

Structure

• Housing- Provides protection for internal components and support for bearings and seals.
• Input shaft- Transmits power from the motor to the gearbox.
• Output shaft- The output of the gearbox, which is connected to the driven load.
• Bearing- Supports the shafts and reduces friction.
• Seal- Prevents lubricant from leaking.
• Gear- Transfers power from one shaft to another with the size and number of teeth determining the gear ratio and torque output.
• Worm- Transfers power between nonparallel shafts with a high gear ratio of 10:1 or higher.
• Housing cover- Protects the gears and seals from external damage and contamination.

Installation

The performance of the reducer depends on correct installation, lubrication, and maintenance.

Shaft Mounting

• Ensure that the shaft of the gear unit and the hole of the gear unit are clean and burr-free.
• Apply a sufficient amount of lubricating oil to the shaft and hole to aid assembly and prevent frictional corrosion.
• Slide the unit onto the driving shaft and fit the key.

Foot Mounting

• Mount the unit securely on a sturdy structure.
• Install the output extended shaft if required.
• Connect the shafts between the input and output with an elastic coupling, and ensure that the deviation of the shaft is within the range of the coupling.
• When installing pulleys or sprockets on two shafts, try to install them closer to the gearbox.
• Do not knock the shafts when installing or removing the transmission components, as it will damage the bearings.

Lubrication and Maintenance

Lubrication

• Oil change: The size 870 and 871 gearbox are lifetime lubricated, except for those working in explosive environments. All other sizes of gearbox need to change the oil according to the working temperature of the equipment. New gearboxes need to replace half of the oil after working for 1000 hours or one year or at the end of the specified service life.

Maintenance

• Check the oil level regularly to ensure proper lubrication.
• Check the coupling and mounting bolts periodically to ensure they are tight.
• Check the oil leakage of the gearbox and the coupling regularly. If any abnormality is found, it should be repaired in time.

Possible Issues and Solutions

Possible Issues	Causes	Solutions
Vibration	Loose bolts, worn bearings, misalignment, or unbalanced load.	Check bolts, replace bearings, align shafts, or balance load.
Noise	Worn gears, bearings, or insufficient lubrication.	Replace gears or bearings, or lubricate properly.
Overheating	Insufficient lubrication, wrong oil, or overload.	Check the oil level and type, reduce the load, or replace the oil.
Oil leakage	Worn seals or damage to the housing.	Replace the seals or housing.
No output	Broken shaft, worn gears, or damage to the housing.	Replace the broken parts or housing.
Abnormal noise during operation	Loose bolts, worn bearings, or worn gears.	Tighten bolts, replace bearings, or gears.
Difficult to start	Low voltage or overload.	Check the voltage and reduce the load.
Short service life	Insufficient lubrication or overload.	Ensure proper lubrication and reduce the load.
