How to determine whether the working condition of WP series worm gear reducer is stable
1、 Temperature index (core red line)Bearing temperature: The infrared thermometer is used to measure the bearing seat of the worm end and worm wheel end, and the normal temperature should be ≤ 75 ℃. The upper threshold is the ambient temperature+40 ℃, and overheating can easily cause lubrication failure.
Oil pool temperature rise: The temperature difference between the oil at the oil window and the environment is ≤ 35 ℃, and the overall oil temperature does not exceed 70 ℃. Long term exceeding 80 ℃ can cause a sudden drop in lubricating oil viscosity and failure.
Shell temperature: The temperature of the surface of the box away from the bearing seat area is ≤ 60 ℃, and the temperature difference between each area is ≤ 10 ℃. Local overheating indicates meshing overload or poor heat dissipation.
2、 Vibration and noise indicators
Vibration value: Measured at the rigid part in the middle of the shell, the double amplitude in the vertical and horizontal directions is ≤ 0.05mm. If the vibration suddenly increases to above 0.08mm, it is mostly due to loose foundation or bearing wear.
Running sound: The whole process is a uniform and soft "buzzing" meshing sound, without sharp metal scraping sound, periodic impact sound or high-frequency whistling sound, and abnormal noise directly points to poor meshing or component damage.

3、 Lubrication and sealing status
Oil state: The oil level is stable at 1/2~2/3 height of the oil window, and the oil is amber without blackening, emulsification, or metal debris. The viscosity of ISO VG320 lubricating oil at 60 ℃ is not less than 50cSt.
Sealing performance: There is no obvious oil droplet leakage on the joint surface between the shaft extension oil seal and the box body, and only a small amount of oil film is allowed to infiltrate the oil seal lip without any oil leakage.
4、 Load transmission stability
Smooth operation: Under rated load, there is no shaking or slipping of the output shaft, no jamming in forward and reverse transmission, and the backlash angle meets the design standards of this model without obvious looseness.
Transmission efficiency: The measured efficiency has reached the manufacturer's nominal value without sustained rapid decline, avoiding abnormal heating caused by low efficiency.
Continuity of working conditions: Running continuously for more than 2 hours without continuous deterioration of all indicators, without sudden temperature rise or vibration jump phenomenon, fully compatible with the working environment requirements of WP series -40 ℃~+40 ℃.
