The difference in lubrication methods between hard-tooth surface reducers and soft-tooth surface reducers directly affects the maintenance frequency, failure rate and service life of the equipment. ‌Hard-tooth surface reducers have higher performance requirements for lubricants, requiring the use of gear oil with high viscosity, containing extreme pressure and anti-wear additives, and stricter maintenance cycles; while soft-tooth surface reducers have relatively low lubrication requirements and can use mineral oil-based lubricants, which are easier to maintain but have weak impact resistance‌. This difference determines that the maintenance strategies of the two types of equipment should be different in actual operation. 1. The impact of differences in lubrication methods on maintenance 1. ‌Different requirements for lubricating oil Selection‌Hard-tooth surface reducer: The tooth surface has high hardness and requires extremely high lubricating film strength. ‌High viscosity industrial gear oil‌ must be selected and contain ‌sulfur-phosphorus extreme pressure additives‌ to prevent tooth surface gluing or pitting under high load. Soft tooth surface reducer: Generally, medium load gear oil (CKC) can be used. It does not have high requirements for extreme pressure performance and has low maintenance costs. Read More

The optimal range of the oil pool inclination angle of ZSC400-22.4-2 gear reducer is usually set between ‌3°~5°‌. This angle design is the core parameter to ensure the uniformity of lubrication. It can ensure that the lubricating oil naturally flows to the large gear side of the low-speed stage, while optimizing the oil-carrying trajectory of the high-speed stage, effectively solving the problem of uneven lubrication. 1. The core role of the inclination angle and the original intention of the design of the standard inclined oil pool is to improve the lubrication conditions of the soft tooth surface reducer, especially in long-term operation or high load scenarios: ‌Lubrication flow direction optimization‌: The inclination angle of 3°~5° uses gravity to allow lubricating oil to flow more smoothly into the meshing area of ​​the low-speed gear, preventing the high-speed gear from heating due to excessive oil stirring power consumption, and preventing the low-speed gear from being short of oil. ‌Remarkable temperature control effect‌: According to actual transformation data, a reasonable tilt angle can reduce the operating oil temperature of the reducer by 5~8℃, and can extend the lubricating oil replacement cycle by more than 30%, which is beneficial to Read More

Judgment ZFY560-112-2 The core of the actual operating load type of the gear reducer is to conduct a comprehensive evaluation based on the ‌drive equipment characteristics‌, ‌working machine operating conditions‌ and ‌field operation data‌. A conclusion cannot be made based on a single indicator. For the hard-tooth surface reducer you are interested in, it is usually necessary to determine whether it is a 'constant load', 'slight impact' or 'strong impact load' by observing the operating noise and vibration, measuring the motor current fluctuations, and comparing the working condition coefficient table. To accurately define the load type of ZFY560-112-2, it is recommended to cross-verify from the following three dimensions: 1. The matching characteristics of the driving source and the working machine (theoretical prediction). This is the most basic basis for judgment. You need to confirm the motor power connected to the reducer, the starting method and the type of back-end load machinery. ‌Constant load‌: If the rear end is connected to a belt conveyor, centrifugal pump or fan that evenly feeds material, and starts smoothly, it will usually Read More

The ambient temperature directly affects the power matching, lubrication status, thermal balance, operating accuracy and service life of the motor and ZSY280-35.5 gear reducer. Abnormal temperature will lead to unbalanced adaptation of the whole machine, increased faults and shortened service life. 1. High-temperature environment (>40℃, exceeding 45℃ is a severe working condition) 1. Impact on the motor: The ambient temperature rises, the heat dissipation of the motor becomes worse, the winding insulation ages faster, and the service life decreases significantly every time the temperature exceeds 10℃; the motor loss increases and the efficiency decreases, so it needs to be used at a reduced capacity, otherwise it is easy to overheat, trip and burn; the bearing grease becomes thinned and lost, causing abnormal noise and jamming. 2. Impact on the ZSY280-35.5 reducer: the viscosity of the lubricating oil decreases, the oil film is easy to rupture, and the tooth surface and the bearing are prone to dry friction, pitting, and gluing; the thermal expansion of the gear and bearing causes the meshing gap to become smaller, the vibration and noise increase, and even stuck and broken teeth; the seals accelerate aging and hardening, resulting in oil leakage, dust and water ingress Read More

The regular inspection record of bearing temperature of TY125 hardened surface reducer should contain the following key information to ensure that the equipment operating status can be traced, abnormalities can be warned, and maintenance is based on: 1. Basic equipment and environmental information ‌Equipment model‌: T Y125 hard tooth surface reducer ‌Installation location‌: such as 'Production Line 3 of the Main Transmission Workshop' ‌Check date and time‌: Accurate to the minute, convenient for trend analysis ‌Ambient temperature‌: Record the ambient temperature during measurement (such as 2 5℃), used to calculate temperature rise‌Operating conditions‌: load status (no load/25%/50%/75%/full load), continuous operation time 2, temperature monitoring core data‌measuring point location‌: clearly marked as input shaft, output ‌Actual temperature value‌ at the bearing end cover of the shaft or intermediate shaft: Use an infrared thermometer to measure the surface temperature of the bearing outer ring or end cover ‌Maximum allowable temperature‌: Generally not exceeding 80℃‌Temperature rise‌: It is recommended to control it within 40℃‌Historical basis Read More

Failure of the backstop of the ZSY224-56-11 reducer will directly affect the one-way braking function of the equipment, especially in working conditions such as belt conveyors and elevators that need to prevent reversal, which may cause serious safety accidents. ‌To determine whether the backstop has failed, it should be comprehensively identified from three aspects: abnormal operation, component inspection and functional testing. The core judgment is based on the reverse rotation of the equipment after shutdown or the inability to effectively lock. ‌1. Reverse rotation occurs after the equipment is shut down. After cutting off the power source, the output end that should have remained stationary rotates in reverse direction, which is the most direct signal of backstop failure. For example, in a conveyor system, if the material causes the belt to slip backward due to gravity, it indicates that the backstop function is lost. ‌2. Abnormal noise and stuck phenomenon‌ (1) Intermittent impact sounds such as 'click' and 'clunk' appear during operation, which may be caused by poor engagement between the pawl and the ratchet wheel or spring failure; (2) A sudden increase in resistance or jamming is felt when starting, and then suddenly released.
