1、 The performance impact of mainstream lubrication methods ZDY125 belongs to a single-stage hard tooth surface reducer, with a gear circumferential speed usually ≤ 20m/s. The industry mainstream uses oil bath/splash lubrication, and high-speed heavy load conditions can be upgraded to oil spray lubrication. The impact of the two methods on performance is significantly different: 1. Oil bath/
1、 The core transmission components are the first to be damaged Bearing: It is the first failed component due to excessive tilt, and the additional bending moment will cause the bearing to bear asymmetric radial/axial forces outside the design. The local contact stress between the rolling elements and the raceway exceeds the standard, quickly causing pitting and peeling, and in severe cases, di
1、 Pre security preparation Confirm that the equipment is shut down and powered off, hang a warning sign reading 'Do not close', and lower the temperature of the gearbox casing to below 40 ℃ to prevent scalding from hot oil splashing. Prepare tools: oil resistant gloves, goggles, fiber free cotton cloth, nylon soft bristled brush, 0.2-0.4MPa clean compressed air gun, dedicated oil drum, 80-1
1、 Preferred posture: Horizontal and horizontal foot installation The installation surface should be kept level, with a longitudinal levelness error of ≤ 0.1mm/m, and calibrated using a level with an accuracy of 0.02mm/m. In this posture, the oil tank completely covers the worm gear meshing area, providing the most thorough lubrication and avoiding local dry wear. It is suitable for over 90%
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
