Components of Worm Reducer

Housing: Provides protection and support for the internal components
Worm Shaft: Transmits torque from the motor to the worm gear
Worm Gear: Transfers motion from the worm shaft to the output shaft
Output Shaft: Delivers power to the driven equipment
Bearing: Supports the rotating components and reduces friction
Seal: Prevents oil leakage and protects against contaminants

Installation

The performance of the worm reducer depends on correct installation, lubrication, and maintenance. There are two common mounting methods:

Shaft Mounting

Ensure that the shaft and the gear unit hole for mounting the gear unit are clean and free from burrs. Apply a sufficient amount of lubricating oil to the shaft and hole to aid assembly and prevent friction corrosion. Slide the unit onto the drive shaft and secure with a key.

Foot Mounting

Mount the unit securely on a sturdy structure. Install an output shaft extension if required. The connection between shafts should use an elastic coupling, ensuring that the shaft misalignment is within the coupling's tolerance. When mounting pulleys or sprockets on two shafts, place them as close as possible to the gearbox. Do not strike the shafts when installing or removing the transmission components, as this may damage the bearings.

Lubrication and Maintenance

Lubrication:

Oil Change: Gearboxes of size 870 and 871 are lubricated for life unless operating in explosive environments. All other sizes of gearboxes require oil change based on the equipment's operating temperature. For new gearboxes, replace half of the oil after 1000 hours of operation, one year, or when the recommended service life expires.

Maintenance:

Regularly inspect and clean the gear unit to remove debris and ensure proper lubrication.
Check for any abnormal noise, vibration, or leaks during operation.
Replace worn or damaged components promptly to avoid further damage.
Follow the recommended maintenance schedule provided in the user manual.

Common Problems and Solutions

Problem	Cause	Solution
Excessive noise	Misalignment, worn gears, lack of lubrication	Align the unit properly, replace worn gears, ensure proper lubrication
Overheating	Insufficient lubrication, excessive load	Ensure proper lubrication, reduce the load
Leakage	Worn seals, damaged housing	Replace worn seals, repair or replace the housing
Low efficiency	Incorrect gear ratio, worn gears	Adjust the gear ratio, replace worn gears
Abnormal vibration	Misalignment, unbalanced load	Align the unit properly, balance the load
Failure to start	Faulty motor, electrical issue	Check the motor and electrical connections
Excessive backlash	Worn gears, improper assembly	Replace worn gears, ensure proper assembly
Gear slipping	Insufficient torque, worn gears
