high torque gear reducer-Frequently Asked Questions (FAQ)
Q: What is the primary difference between the ZDY and ZLY series?
A: The ZDY is a single-stage reducer (ratios 1.25 to 6.3), while the ZLY is a two-stage reducer (ratios 6.3 to 20). ZDY offers higher efficiency and a shorter axial length, whereas ZLY is used for higher reduction ratios.
Q: How do I maintain the ZDY gear reducer?
A: Maintenance is straightforward. Check the oil level via the sight glass or dipstick regularly. Change the oil after the initial run-in period, and then every 2,000–3,000 operating hours (or as dictated by oil analysis). Ensure the top breather plug remains clean and unblocked.
