To avoid overloading of soft tooth surface ZQA850-15.75-2 gear reducer, you can start with reasonable design Selection, optimize operation control, strengthen maintenance, etc. The specific methods are as follows:
Reasonable design and Selection
Accurate load calculation : Before selecting a reducer, the load size needs to be accurately calculated, including static load, dynamic load and impact load, etc. Consider various working conditions during the start-up, braking and operation of the equipment to ensure that the rated load of the selected reducer is greater than the actual working load.
Choose a suitable transmission ratio : reasonably determine the transmission ratio of the reducer according to the speed requirements of the working mechanism to avoid excessive torque caused by unreasonable transmission ratio.
Optimized operation control
Avoid frequent start and stop : minimize the frequency of start and stop of the reducer, because every time the reducer starts and stops, the reducer will bear a large impact load, which is often so easy to cause overload. If necessary, do not turn on and off the device frequently. For devices that work intermittently, a reasonable standby mode can be set.
Control the running speed : Run according to the rated speed of the reducer and do not increase the running speed at will. Too fast speed may increase the load and exceed the load-bearing capacity of the reducer. At the same time, to avoid sudden speed changes, you should slowly increase or decrease the speed.
Set up an overload protection device : install an overload protection device, such as torque limiter, thermal relay, etc. When the reducer load exceeds the set value, the overload protection device will operate in time to cut off the power transmission or issue an alarm signal to prevent damage caused by overload operation.
Strengthen maintenance
Regularly check the wear of gears : Check the wear of gears regularly. For important gears in key areas, the wear of the tooth surface should be less than 10% of the original tooth thickness. For the wear of the tooth surface of the general gear, when it is less than 20%-30% of the original thickness, it should be replaced or repaired in time to avoid overload due to the loss of load-bearing capacity caused by gear wear.
Maintain good lubrication : Choose lubricating oil of appropriate viscosity and quality, change the lubricating oil regularly, and keep the lubricating oil clean to reduce friction resistance during gear meshing, reduce energy loss, and avoid intensifying gear wear and increasing load due to poor lubrication.
Ensure installation and assembly accuracy
Correct installation of reducer : During installation, ensure the coaxiality of the connection between the reducer and the driving equipment and the working mechanism. If the coaxiality error is too large, the reducer will generate additional radial and axial forces, resulting in overload. At the same time, the reducer must be firmly installed on the foundation to prevent vibration and displacement during operation.
Ensure the gear assembly accuracy : When assembling gears, the meshing clearance of the gear must be strictly controlled. Too large or too small gaps will affect the normal transmission of the gear, resulting in uneven load distribution and even overload.
