Use a sound level meter and spectrum analyzer to check the noise of the ZSY250 gear reducer. You can refer to the following steps: Use of sound level meter 1. Preparation: Calibration: Before use, the sound level meter must be calibrated to ensure the accuracy of the instrument measurement. The calibrator can generate a signal of a known sound pressure level to calibrate the sound level meter. Select measurement mode: According to the characteristics of reducer noise, select the appropriate time-weighted mode. For example, the fast response mode is suitable for measuring stable noise, and the slow response mode is suitable for measuring noise with large fluctuations. Set measurement range: Estimate the sound pressure level range of the reducer noise and set a suitable measurement range to avoid inaccurate measurement results due to improper range selection. 2. Determine the measurement point: Generally, multiple measurement points can be selected around the housing of the reducer, such as 1 meter away from the housing and the height is approximately the same as the height of the central axis of the reducer. You can also choose the input, output, and gear shaft located at the transmission chain. Read More

When installing the ZQ500-20.49-2 reducer, in addition to coaxiality, the following issues should be paid attention to: Installation position and basic position selection: The reducer should be installed in a smooth, dry and clean position to ensure that there is enough space for maintenance and inspection. At the same time, it is necessary to facilitate staff to get close to oil standards, ventilation plugs and oil drain plugs. Foundation fixation: The reducer must be installed on a solid foundation or base to prevent vibration and displacement during operation. The strength and stiffness of the foundation should be able to withstand the weight of the reducer and the load during operation. Installation Direction: Determine the optimal installation direction for the reducer according to the manufacturer's recommendations, usually horizontally, but there are some special models that can be installed vertically. The installation direction will affect the lubrication effect and heat dissipation performance. If the installation direction is incorrect, it may lead to poor lubrication or poor heat dissipation, which will affect the service life of the reducer. Fixing method: Use the correct fasteners to securely secure the reducer to the bottom Read More

When installing the ZQ350-25-III reducer, the steps to check the coaxiality of the motor shaft and the input shaft of the reducer are as follows: 1. Preliminary correction: Use visual measurement to compare the front and back of the docking hand with the steel ruler, so that the front and back of the motor and reducer are initially aligned to reduce the start error, and calibrate the motor center high for the subsequent dial meter to reduce the error. 2. Proofread the center line contour: Install the dial meter in the main view direction, fix the magnetic seat of the dial meter to the input shaft of the reducer (if the reducer is inconvenient to rotate, you can also install the magnetic seat on the motor to take over), rotate the reducer to take over (or the motor shaft) for one turn, record the readings of the dial meter at the upper and lower points, and calculate the reading differences between the upper and lower points of the dial meter ΔL1. Then, at the four anchor screws of the motor, add ΔL1/2+(0.10~0.15) mm thick gaskets, of which 0.10~0.15mm It is an experience value, used to compensate for the Read More

The following are some cases that may cause the output shaft of the BLD16-17-18.5KW cycloid reducer to deform: Overload operation: Excessive torque, such as sudden load change, start-up impact, overload protection failure, etc., which will cause the torsional stress of the output shaft to exceed the yield strength of the material, resulting in the shaft bending or deformation. For example, when the equipment driven by the reducer suddenly becomes stuck and the motor continues to output power, it may cause the output bearing to be subjected to excessive torque. Installation concentricity error: The motor and reducer are not assembled, and the output shaft will bear radial forces from the input end of the reducer. This radial force will force the output shaft to bend and deform for a long time, and the bending direction will continue to change as the output shaft rotates. The greater the concentricity error, the faster the output shaft will deform. Frequent start and stop: During acceleration and deceleration, if the instantaneous torque of the reducer output shaft exceeds 2 times its rated output torque, and this Read More

To prevent the output shaft of the BLD13-35-3KW cycloid pin wheel reducer deformation, you can start from the following aspects: Reasonable Selection and correct installation Selection: Select the appropriate reducer according to the actual load conditions to ensure that the rated output torque of the selected reducer is greater than the actual maximum working torque required. Generally speaking, the maximum operating torque required by the user should be less than 2 times the rated output torque of the reducer. Accurate installation: During installation, it is necessary to ensure that the output shaft of the reducer is consistent with the shaft of the driven equipment, and calibrate professional tools such as laser centering instruments. The concentricity error should be controlled within 0.05mm/m. At the same time, it is strictly forbidden to use hammers to hit the output shaft of the reducer to prevent excessive axial or radial forces from damaging the bearings or gears. Control operating conditions to avoid overload operation: operate strictly according to the rated load of the reducer, avoid excessive load during startup, stop and operation, and prevent excessive output shaft from being caused.

The requirements for lubricating oil quantity of different models of worm gear reducers are mainly affected by factors such as center distance, power, etc. There are generally the following differences: According to the center distance: ordinary cylindrical worm gear reducers with a center distance of 50-100mm, the oil filling amount of oil tank lubrication is 0.3-0.8L. When the center distance is 100-160mm, the oil injection volume is 0.8-2L. When the center distance is 160-250mm, the oil injection volume is 2-5L. When the center distance is 250-400mm, the oil injection volume is 5-10L. For arc cylindrical worm reducer, when the center distance is 80-125mm, the oil injection volume is about 0.5-1.5L. When the center distance is 125-200mm, the oil injection volume is 1.5-3L. When the center distance is 200-315mm, the oil injection volume is 3-8L. Estimation by power: For single-stage transmission reducers, you can refer to each transmission Read More
