To eliminate the axial movement of the RX121-37KW reducer, the core is to start from the three dimensions of 'positioning, tightening, and compensation' and take corresponding measures to target the root causes of the movement (such as bearing failure, loose positioning parts, and excessive clearance). 1. Repair or replace core positioning components (the most direct and effective). The main cause of axial movement is the failure of positioning components such as bearings, shaft shoulders, and thrust rings. Prioritize inspection and replacement of these wearing parts. Bearing-related repairs: If the movement is caused by excessive bearing clearance or damage to the thrust bearing, it is necessary to replace the same type of high-precision bearing (it is recommended to choose P6 and above precision). During installation, ensure that the matching clearances between the inner ring of the bearing and the shaft, and the outer ring and the box meet the design requirements (usually H7/js6 fit). Adjustment of the shaft shoulder and positioning ring: If the shaft shoulder is worn or the positioning ring is loose, the shoulder can be repaired and re-welded and reprocessed to standard size, or a new positioning ring can be replaced to ensure that it can firmly hold the inner ring of the bearing and limit the Read More

To determine whether there is axial movement in the RX67-2.54-5.5KW-M1-0° reducer, you can combine 'direct measurement' and 'indirect observation' methods. The former is precise and quantitative, and the latter is rapid and qualitative, covering scenarios with or without professional tools. 1. Direct measurement method (accurate judgment, requires shutdown operation) directly detects the axial displacement of the shaft through special tools, which is the core basis for judging movement and is suitable for maintenance or when movement is suspected. Tool preparation: dial indicator (accuracy 0.01mm), magnetic watch stand, cleaning cloth, wrench. Operation steps: Stop the machine and cut off the power, wait for the reducer to cool down completely (thermal expansion and contraction will affect the measurement accuracy), and clean the oil dirt and iron filings at the end of the output shaft/input shaft. Attach the magnetic meter base to the flat surface of the reducer case (make sure the meter base is not loose and serve as a fixed reference), adjust the dial indicator head so that it is vertically aligned with the center of the end face of the shaft, and the meter head is pre-compressed Read More

To ensure the relative position accuracy of the motor and the SCWS80-50-2 reducer, the core is to control the errors throughout the entire process from base leveling, shaft alignment to component connection through 'datum alignment, step-by-step fixing, and precise measurement' to ultimately achieve compliance with the three key parameters of levelness, coaxiality, and spacing. 1. Preliminary preparation: Set the benchmark, select tools, and eliminate basic errors. This is the prerequisite for ensuring position accuracy and avoiding subsequent adjustment difficulties caused by deviations in initial conditions. Base surface treatment and leveling: Thoroughly clean the installation base of the motor and reducer, remove oil stains, rust and raised debris, use a flatness ruler to check the flatness of the base, the error must be ≤0.05mm/m; if the base is uneven, use precision copper spacers (thickness accuracy 0.01mm) to level the bottom of the base to ensure that the installation surface is at the same level. Preliminarily fix the reducer on the base, and use a level with an accuracy of 0.1mm/m to close the upper plane and Read More

The backlash range of worm gear reducers varies depending on the model, accuracy level and usage scenario. The following are the typical standards for each model: 1. The backlash range of general-purpose worm gear reducer ‌ cylindrical worm reducer ‌ is usually ‌0.1~0.3mm‌, which is suitable for general-purpose worm gear reducers. High-precision industrial transmission applications (such as dividing heads) need to be controlled within ‌0.01~0.04mm‌‌arc-contract The backlash standard of the worm reducer is similar to that of the cylindrical worm, but due to the optimization of the tooth shape, it can be appropriately relaxed to ‌0.15~0.5mm‌ (such as WH series). 2. Double-stage worm gear reducer: Due to accumulated errors, the backlash of double-stage transmission is usually larger than that of single-stage, ranging from about 0.2 to 0.6mm‌. 3. Adjustment standards for special working conditions ‌Servo transmission‌ requires strict control of backlash, generally ≤ ‌0.15mm‌ (or ≤30 arcmin). ‌Heavy load or high temperature environment‌The side clearance can be appropriately increased to ‌0 Read More

NCZD315-900-1 planetary gear reducer relies on the core advantages of ultra-large transmission ratio (900) and high torque carrying capacity. It is mainly used in heavy-duty industrial fields with extremely high demand for 'low speed and high torque'. It is especially suitable for large equipment that requires continuous heavy-load operation. It can be divided into 4 core application fields. 1. Mining and coal industry: Suitable for heavy-duty conveying and crushing equipment. The mining industry has harsh working conditions and heavy loads, and has extremely high requirements for the impact resistance and torque output of the reducer. This model can accurately match two types of key equipment: heavy-duty scraper conveyor/belt conveyor: In underground or above-ground coal and ore transportation scenarios, the equipment needs to drive long-distance, large-bandwidth conveyor belts (such as a bandwidth of more than 1.6m), and needs to cope with material impact loads. The ultra-large transmission ratio of the reducer can reduce the high speed of the motor to a low speed of about 1.67r/min, while outputting tens of thousands of N·m of torque. Read More

The core of the working principle of the NCZD500-1250-1 planetary gear reducer is planetary gear train meshing transmission, which achieves an ultra-large reduction ratio through the synergy of the sun gear, planetary gear, and internal ring gear; its performance advantages revolve around 'ultra-large transmission ratio, ultra-high torque, and high stability', making it perfectly suitable for ultra-heavy and low-speed working conditions. 1. Working principle: Three-stage meshing transmission of planetary gear train. This reducer is a single-stage planetary transmission structure ('1' in the model represents 1st stage). Through the transmission path of 'sun gear active→planetary wheel rotation→planetary carrier output', the high speed of the motor is converted into low speed and high torque. The specific process is divided into 3 Step: Power input: The sun gear receives power and the output shaft of the motor is rigidly connected to the sun gear of the reducer. After the motor is started, it drives the sun gear to rotate at high speed (for example, the motor speed is 1500r/min). The sun gear serves as the driving wheel and drives the surrounding 3-4 wheels through tooth surface meshing. Read More
