RF67-11.54-2.2kW reducer belongs to R series hard tooth surface helical gear reducer, frame number 67, reduction ratio 11.54, adaptable to 2.2kW The motor, with its characteristics of small size, medium torque and impact resistance, is highly consistent with the working conditions of small and medium-sized auxiliary equipment in mining machinery. The specific adapting working conditions are as follows: 1. The power transmission of small mining conveying equipment is suitable for small belt conveyors, scraper conveyors, screw feeders and other equipment underground or on the ground, such as scattered material transfer in mine tunnels, quantitative feeding of powder in mineral processing plants, and material transportation at the discharge port of silos. The reduction ratio of 11.54 can convert the motor's high speed into medium and low speed output (when the input is 1450r/min, the output speed is about 125.6r/min). The 2.2kW power is enough to drive a small conveying mechanism. The hard tooth surface gear can cope with the slight impact load when conveying materials such as ore and coal powder. Read More

The advantages and disadvantages of hard tooth surface reducer and soft tooth surface reducer are as follows: 1. Advantages and disadvantages of hard tooth surface reducer 1. Advantages: (1) The tooth surface hardness is high, generally above HRC58, and the wear resistance is excellent. It can withstand higher contact stress and impact load. The load-bearing capacity is 2-3 times higher than that of the soft tooth surface reducer of the same specification. It is suitable for heavy load, high speed, and frequent start and stop conditions. (2) The transmission efficiency is high, reaching 96%-98%. The tooth surface has been quenched and ground, with high tooth profile precision, small meshing clearance, lower vibration and noise during operation, and strong operating stability. (3) Long service life. Under the conditions of standardized lubrication and maintenance, the service life can reach 10-20 years, which is much higher than that of soft tooth surface reducers, which can reduce the frequency of equipment replacement and shutdown maintenance. (4) Compact structure, with the same load capacity, the volume and weight are 15%-30% smaller than that of soft tooth surface reducers, saving installation space and adapting to a variety of compact equipment Read More

BLD16-23-22KW cycloidal pinwheel reducer (horizontal, 22kW heavy load) recommends the use of ISO VG 150/220 extreme pressure (EP) industrial gear oil. Adjust accordingly when the ambient temperature and working conditions are different. The following are recommendations and supplementary instructions: Normal working conditions at normal temperature (0-40℃): Priority is given to ISO VG 150 extreme pressure industrial gear oil, which meets 22kW It meets the anti-wear and load-bearing requirements of power, adapts to most continuous operation scenarios, has strong versatility and high cost performance. Heavy load/high temperature working conditions (>40°C, impact load, long-term full load): Upgrade to ISO VG 220/320 extreme pressure industrial gear oil to improve oil film strength and thermal stability and reduce the risk of wear. Low temperature working conditions (-10-0℃): Use ISO VG 68/100 extreme pressure industrial gear oil to avoid high viscosity at low temperatures, which may cause difficulty in starting and poor lubrication.

JudgmentRXF107-NA432-30KW-D350-M4 Whether the gear meshing of the reducer is good or not requires a combination of static detection during shutdown and dynamic monitoring during operation to comprehensively determine from the tooth surface contact status, operating parameters, vibration and noise, etc. The specific steps are as follows: 1. Static detection during shutdown (core determination method) 1. Red red powder coating detection method (the most intuitive) (1) Clean the observation hole of the reducer to ensure that there is no oil or impurity on the gear surface; (2) Evenly apply a thin and uniform layer of red red powder (or blue oil) on the tooth surface of the driving gear; (3) Manually turn the car slowly for 3~5 circle, so that the driving and driven gears are fully meshed; (4) Observe the contact traces on the tooth surface of the driven gear. The criterion for good meshing is: the contact traces are distributed in the middle area of the tooth surface, with no upward, downward, left, or right phenomena; contact area: hard tooth surface gear ≥ 60%, soft tooth surface gear ≥ 70%; traces are continuous without interruption, no obvious Read More

Poor gear meshing of the GR107-Y3-4P-11.59 reducer may indeed cause safety accidents. The core risks are mechanical structure damage, electrical system overload and personal injury. 1. Safety accidents caused by damage to mechanical structures ‌ 1. Risk of gear breakage or tooth chipping ‌: ‌Consequences‌: Broken gear fragments may fly, causing scratches and smashing of personnel (especially in open transmission systems). The gear falling off will cause the transmission to be interrupted and cause the equipment to lose control (such as the emergency stop of the elevator or the sudden stop of the conveyor line causing material accumulation and collapse). ‌Cause‌: Long-term overload causes fatigue fracture of the tooth root (exceeding the material fatigue limit); sudden impact load (such as falling heavy objects) causes the gear to collapse due to instantaneous overload. 2. Risk of bearing locking or fragmentation: ‌Consequences: Bearing locking causes severe vibration of the shaft system, which may cause the reducer housing to crack, bolts to loosen and fall off, and even the equipment toppling.
