How to eliminate "soft feet" during the installation of ZD15 soft tooth surface gear reducer
The "soft feet" in the industrial field are installation problems caused by the landing point of machine equipment not being on the same plane as the supporting foundation. The ZD15 reducer needs to be handled according to different types of soft feet:
1. Parallel soft feet (the most common type)
This is the most common type of soft foot for the installation of ZD15 reducers, which is often caused by short foot legs, non coplanar base plates/installation pads, and missing foot pads.
Solution: Add sufficient stainless steel gaskets to eliminate the swinging effect. It is recommended that the number of gaskets should not exceed 4 to correct it.
2. Bent feet/outward curved soft feet

The cause is that the bottom of the reducer foot is inclined at an angle to the base, and laser detection will display a conical air gap.
Solution: Polish the inclined foot contact surface, correct the angle, and readjust the gasket to ensure that the foot is completely in contact with the base.
3. Sticky feet (spring feet)
The cause is the accumulation of dirt, rust, or grease between the foot and base of the reducer, which can lead to inaccurate gap detection.
Solution: Thoroughly clean the contact surface between the foot and base, remove accumulated impurities, and retest and adjust the gasket to eliminate them.
4. Inducing soft feet
Induced by external factors, common causes include coupling/pipeline stress, excessive belt/chain load, and improper tightening of lifting bolts.
Solution: Investigate and eliminate the external forces causing the problem one by one, adjust the pipeline stress, correct the load, and loosen the bolts that were mistakenly tightened. Multiple soft foot tests may be required during the process to confirm.
