I. Precautions before installation
1. Before using this machine, the mounting shaft should be cleaned. Check the mounting shaft for any damage or dirt, and remove all such items.
2. The operating temperature of the speed reducer is 0～40 ℃.
3. Check whether the fit dimensions of the hole (or shaft) connected to the reducer meet the requirements. The tolerance of the hole should be H7 (the tolerance of the shaft is H6).
4. Before use, replace the blockage at the highest position with an exhaust plug to ensure that the gas inside the reducer is discharged during operation.
II. Installation of the speed reducer
1. The speed reducer can only be installed on a flat, shock-absorbing, and torsion-resistant support structure.
2. Under no circumstances should you use a hammer to knock pulleys, couplings, pinions, or sprockets onto the output shaft, as this will damage the bearings and shaft.
III. Use and Maintenance
1. Gearbox Basics: After installation, check for smooth operation. Before formal use, a no-load test must be performed. If normal operation is observed, gradually increase the load.
2. The speed reducer must not be used beyond its rated load.
3. Before and during use, the oil level of the reducer should be checked to ensure it is normal. The machine has been filled with lubricating oil before leaving the factory. The name of the lubricating oil is: Medium-load industrial gear oil GB5903-86220.
IV. Oil Change System
The lubricating oil should be changed after the machine has run for 300-400 hours for the first oil change, and then every 1500-2000 hours thereafter. In harsh working environments with high temperatures and high dust levels, the lubricating oil should be checked every half month. If contamination is found in the lubricating oil, it should be replaced immediately to keep the lubricating oil clean, extend the service life of the reducer, and improve economic efficiency.
V. Oil Change
When changing the oil, wait until the gearbox has cooled down to a point where there is no risk of combustion, but it should still be kept warm. This is because once completely cooled, the oil viscosity increases, making draining difficult. (Note: Disconnect the power supply to the transmission device to prevent accidental energization!)
