It is necessary to stop the machine and cut off the power, and wait for the gearbox to cool naturally to below 40 ℃ to avoid scalding from hot oil or oxidation of the oil. Thoroughly clean the oil filling port, oil level gauge, and surrounding 5cm area of oil and dust to prevent impurities from entering the box. Prepare refueling tools, butter guns, and waste oil collection containers with f
1、 Safety confirmation before refueling The machine must be shut down and the power must be cut off: hang a "Do Not Close" warning sign to prevent accidental start-up or power on. Wait for the oil temperature to drop to a safe range: it is generally recommended to lower the shell temperature to around 40 ℃ before operation; It is not recommended to drain or add oil when the oil temperature e
1、 Accurate selection and performance enhancement of oil products L-CKE/P 220 # worm gear special extreme pressure oil must be selected, containing sulfur and phosphorus extreme pressure additives. It can still form a high-strength chemical adsorption film on the tooth surface under low load, avoiding the oil film from being squeezed out of the meshing area. It is prohibited to use ordinary
1、 External connection class jitter self repair Tighten all loose fasteners: Use a torque wrench to tighten the reducer foot bolts, box connecting screws, and coupling fastening sleeves diagonally according to the original factory's specified torque, eliminating transmission clearance impact. Calibrate the coaxiality of the shaft system: Use a laser centering instrument to detect the axis of
1、 Initial assessment of appearance and location of leakage points 1. After cleaning, observe again: Thoroughly wipe off all oil stains on the outer surface of the reducer, run it without load for 10-15 minutes, track the starting position of the newly leaked oil stains, and avoid mistaking the splashing oil from surrounding equipment as oil leakage from the machine. 2. Key area investigatio
Step 1: Accurately locate the oil leakage point Clean all oil stains on the gearbox casing, run the equipment for 10-15 minutes before stopping, and trace the source of leakage along the direction of oil flow. Focus on investigating four types of high-frequency leakage locations: output/input shaft oil seal, box joint surface, observation window sealing position, and around the breathable pl
1、 The core influence of viscosity on power Low viscosity: Insufficient oil film thickness can lead to direct metal contact during tooth meshing, resulting in a sudden increase in friction coefficient and a decrease in transmission efficiency by 3% to 5%. The actual rated power that can be carried is greatly compressed, and long-term operation can cause tooth surface pitting and wear, further l
1、 Core Impact Mechanism The transmission loss increases, and the effective output power is consumed: lubricating oil that has exceeded its service life will oxidize and deteriorate, generating sludge and gum. Either the viscosity is too high, greatly increasing the gear oil stirring resistance, or the viscosity is too low, unable to form a stable oil film, resulting in a sudden increase in mes
