The design life of the core transmission components (sun gear, planetary gear, inner ring gear, planetary carrier, bearings) of P3SA16 planetary gearbox under rated working conditions is usually 20000 hours (about 2.3 years), and the actual life is significantly affected by load, lubrication, installation, and maintenance. Core component lifespan and influencing factors Bearings: As the most
The replacement cycle of the sealing and protective components of P3SA17 planetary gearbox is based on the working conditions and component types, as follows: 1、 Routine replacement cycle for core seals Input/output shaft skeleton oil seal (double lip with dust lip): Under standard operating conditions (load ≤ 80%, temperature 20-40 ℃, clean and dry environment), the preventive replacement c
SBD50-1.5KW-60 belongs to the SBD series Shenke special reducer, which is a combination of planetary cycloid and spiral bevel gear reduction. Common faults are related to lubrication, installation, and component wear. The corresponding specific solutions are as follows: 1. Leakage of oil Common reasons: This reducer is often used in dusty working conditions such as metallurgy and cement, and
NGW-L-F31-4.43-11KW belongs to the NGW series planetary gearbox, and its base is preferably made of cast iron. Low carbon steel or low-alloy high-strength steel welding parts are also commonly used, and corresponding welding materials need to be matched. The specific material selection is as follows: 1. Base material (machine base body material) HT300 gray cast iron: This is a commonly used
ZQ650-25-IZ belongs to the ZQ series reducer, and common errors in its installation and fixation are mainly concentrated in the base not meeting standards and improper bolt fastening. This can be avoided through standardized basic construction, precise control of fixed processes, and post installation review and maintenance. Specific measures are as follows: 1. Standardize basic construction an
ZQ750-48.57-1 reducer shaft alignment errors are mostly radial, angular, and comprehensive deviations, and connection errors are often caused by improper coupling and keyway matching. You can follow the process of correcting the alignment deviation first, then solving the connection problem, and finally verifying the effect. The specific method is as follows: 1. Correction of axis alignment err
To determine the effectiveness of the vibration signal of QJRS-D280-100-1P heavy-duty gear reducer, the core is to use "quantitative analysis of noise interference level+equipment feature matching" to eliminate invalid signals (such as environmental noise and installation interference) and retain effective signals that can reflect the true state of the equipment. Here are 8 straightforward judgmen
QJRS-D-450-80-I, as a heavy-duty gear reducer, usually uses oil immersion lubrication in an oil tank. The depth of the oil tank affects the immersion depth, which in turn has a significant impact on the operating noise from the aspects of oil stirring resistance and lubrication effect. Both shallow and deep can cause abnormal noise increase. Only when it is at a reasonable depth can the equipment
