1、 Installation posture and oil level foundation verification Horizontal calibration of the machine body: Use a level to test the machining reference surface of the reducer, with a horizontal error of ≤ 0.1mm/m, to avoid tilting and causing local oil shortage or oil accumulation overheating. Accurate oil level confirmation: After adding the specified type of lubricating oil, let it stand for

1、 Before installation Confirm lubrication method: FA series mostly uses oil pool splash lubrication; If forced lubrication is required, it is necessary to first confirm that the oil pump, oil circuit, pressure gauge, and oil pressure switch are installed in place. Check the oil: The gear oil specified in the user manual or nameplate must not be mixed with different brands, viscosity grades,

1、 Suitable for gear replacement scenarios The noise characteristics are periodic "clicking" metal impact sounds, with significantly intensified abnormal noises during start stop and load, and a large amount of metal iron filings found during oil discharge. Upon dismantling and inspection, it was found that the tooth surface had worn more than one-third, with extensive pitting and peeling, b

1、 Step 1: Preliminary assessment through exclusive noise features The noise caused by gear pair damage has clear and exclusive characteristics, which can be directly distinguished from other faults: 1. Periodic "click/clang" impact sound: The rhythm is strictly synchronized with the gear speed, and there are corresponding impacts per revolution, mostly pointing to tooth breakage and tooth s

1、 Accurate selection based on sealing parts Box body joint surface (box cover and box seat joint): Under normal working conditions, choose oil resistant silicone flat sealant, such as Kraft K-5875 and double bond DB9587, which can fill small gaps of ≤ 0.5mm in castings. After curing, it has good elasticity and can offset the vibration deformation of the shell, suitable for the sealing requirem

1、 Low temperature condition (ambient temperature ＜ -10 ℃) -10 ℃~-25 ℃ Conventional low temperature: Cold resistant modified oil resistant silicone sealant is selected for the joint surface of the box, such as double bond DB9587, with a temperature resistance coverage of -40 ℃~150 ℃. It will not crack hard or brittle at low temperatures and can fill casting gaps of ≤ 0.5mm. When the gap between

1、 Differences in no-load losses of different types of reducers 1. Cylindrical/helical gear reducer The structure is relatively simple with few rotating parts, and the no-load losses mainly come from bearing idle friction, oil seal lip sliding, and oil stirring. Due to the long tooth contact line and smooth meshing, helical gears have lower meshing losses than spur gears; But the herringbone

The single-stage planetary gear reducer represents one of the most widely adopted reducer designs available today, featuring the lowest no-load loss among common reducer categories. Standard single-stage planetary units achieve a no-load transmission efficiency ranging from 95% to 97%. Certain high-precision servo-grade planetary models can even exceed 97% efficiency under no-load conditions. This
