The hard-toothed surface reducer has strong load-bearing capacity and high gear processing accuracy. The lubricating oil state directly affects the service life of the gear. The lubrication control standards are more stringent and the oil-change period is shorter. The soft-toothed surface reducer has a relatively lower load-bearing load, higher gear tolerance, better lubrication fault tolerance, and the oil-change period can be extended appropriately. Lubrication and oil change cycle of soft tooth surface reducer (representative models: ZQ, ZL, ZS and other traditional series). The first oil change of the new machine must be completed after the trial operation of the new machine reaches 500 to 700 hours. The first oil change needs to be completed. Oil change under normal operating conditions. Continuous operating conditions: Change lubricating oil every 6 months, or every 2500 to 3000 hours of operation. Intermittent operating conditions: Complete oil change once every 12 months at most. In harsh environments (dusty, humid, high-temperature environments), the oil change cycle is directly halved. Lubrication and oil change intervals of hard tooth surface reducer (representative models: DB/DC, DF, S, K, F, R, B3SH, H/ Read More

To detect the vibration of the base of the NGW61-3.15 planetary gear reducer, you can select instruments according to the idea of basic measurement → precise analysis → auxiliary verification. Priority is given to testing equipment that adapts to the on-site working conditions of the reducer and is highly portable. The details of various tools are as follows: 1. Basic measurement category: vibration core detection equipment (direct collection of vibration parameters) portable handheld vibration meter (vibration measuring pen) The most common testing instrument on site can directly obtain the effective value of vibration speed (mm/s), vibration acceleration and displacement data of the reducer frame. The measurement results can be compared with the GB/T 29531 specification to determine whether it exceeds the standard. The equipment is easy to operate and suitable for quick on-site inspections and preliminary vibration assessments. The online vibration sensor supporting data collector is suitable for long-term continuous monitoring of equipment. The piezoelectric acceleration sensor is fixed on the bearing seat and foot of the machine base to continuously collect vibration signals; the supporting collector can store historical data and track vibration Read More

Oil leakage of P series planetary reducer is by no means a simple 'oil leakage' phenomenon, but a fuse that causes lubrication failure. As the lubrication system collapses, the transmission performance of the equipment will drop sharply, and the wear of core components will be multiplied. In the end, it will not only significantly shorten the service life of the equipment, but may even cause catastrophic shutdowns. 1. Comprehensive decline in transmission performance. The loss of lubricating oil means that key meshing components such as planetary gears and sun gears have lost their necessary protective barriers. Under conditions of insufficient lubrication, the frictional resistance between components increases significantly, resulting in a significant reduction in overall transmission efficiency. At the same time, the lack of oil will break the original meshing gap balance, causing the equipment to be accompanied by severe vibration and harsh noise during operation, and the output torque will also become extremely unstable, seriously weakening the operating accuracy and stability of the equipment. 2. Accelerated damage of core components When the lubrication system fails, gears and bearings will be forced into the harsh situation of 'dry friction'. Read More

In view of the shafting alignment and connection errors that may occur in the actual operation of the ZQ750-48.57-1 reducer, it is recommended to follow the standardized operation process of 'first correct the alignment deviation, then solve the connection problem, and finally verify the operation effect.' The specific correction and processing methods are as follows: 1. Precise correction of shafting misalignment. Shafting misalignment mainly manifests as radial, angular and comprehensive misalignment. The correction process needs to be strictly standardized: early preparation and rough adjustment: first clean the oil dirt and impurities on the surface of the coupling, and check whether the shaft body is bent. If the radial runout of the shaft exceeds 0.05mm, it must be straightened or replaced first. Then, use a ruler or feeler gauge to perform rough alignment and initially align the two halves of the coupling to avoid excessive deviation during subsequent fine adjustments. At the same time, it is necessary to use a feeler gauge to check the equipment base to completely eliminate the 'soft foot' problem of poor contact between the base and the bottom plate. In terms of measurement tools, laser alignment instruments are preferred and can also be used in regular scenarios. Read More

Regarding the oil leakage problem of the ZQD350-163.31-II soft tooth surface reducer, in fact, it can be effectively prevented by starting from the four key links of sealing, lubrication, assembly and daily operation. Specifically, you can do this: First of all, you need to 'seal' the line of defense. For the shaft end seal, it is recommended to use oil-resistant and wear-resistant fluorine rubber (FKM) double-lip oil seal, which is better able to adapt to temperature changes and has a longer life than ordinary nitrile rubber. If there is a lot of dust on site, a labyrinth seal can be added to the outside to block impurities. For the joint surface of the box, it must be cleaned before assembly, and anaerobic sealant (such as Loctite 587) should be applied evenly, paying attention to apply it in diagonal order to prevent faults. In addition, the oil sight glass and breathing valve are also places prone to oil leakage. Regularly check whether the sealing ring of the oil sight glass is hardened, and replace the breathing valve with a style with a two-stage filter. Clean the filter every six months to prevent excessive internal pressure from squeezing out oil. Read More
