Precautions for installation of gearbox
The installation site of the decelerator (accelerator) should be separated from thermal radiation. If installed in a very hot or cold place, there must be measures for cooling and lubricating oil heating to ensure normal start-up.
The concrete foundation or metal base plate for installing the reducer must have sufficient rigidity; The anchor bolts should be buried at sufficient depth and leveled with shims. The thickness of the shims should not be less than 1mm; To ensure stable and deformation free operation of the load.
Find the level and align it with the power machine and working machine separately.
The accuracy requirement for a spirit level is generally 0.02~0.05mm/m. The spirit level extends outward from the horizontal plane of the machine body or is a machined surface parallel to the horizontal plane. The higher the accuracy of the alignment, the better. It is necessary to consider the compensation ability of the coupling used for the alignment error and the allowable deviation. Generally, the axis angle error should not exceed 10 "and the translation error should not exceed 0.1mm.
The rust inhibitor and anti-corrosion agent on the shaft extension must be cleaned thoroughly before installing the coupling, sprocket and other components on the shaft extension. Tools such as sandpaper, files, scrapers, etc. that are prone to damaging the surface of the shaft should not be used to remove rust inhibitors and preservatives. When installing couplings, sprockets, etc., heavy hammer strikes should not be used, and the method of thermal expansion and contraction should be adopted.
The axial force generated by the sprocket and pulley transmission on the shaft extension should ideally be directed towards the installation foundation.
If a hydraulic coupling is used for the connection with the power machine. Due to the large mass of the hydraulic coupling and the significant centrifugal force during start-up, the gravity of the hydraulic coupling should be avoided. All centrifugal force should act on the reducer shaft extension, meaning that the hydraulic coupling should not be suspended on the reducer shaft extension, but should be supported together with the power machine. This way, the support point of the shaft extension does not produce additional bending.
Compared with ordinary deceleration motors, deceleration stepper motors can achieve speed and position control, while ordinary deceleration motors cannot achieve positioning control.
