Frequently Asked Questions
Q1: What is the typical lifespan of the ZD70 gearbox under continuous operation?
A: With proper lubrication and maintenance, the ZD70 can operate reliably for over 5–8 years depending on load conditions. The oil lubrication system significantly reduces gear wear, extending service life.
Q2: Can the gearbox be used with motors other than standard IEC frames?
A: Yes, we can customize the input flange and shaft dimensions to match your motor – please provide your motor details for a tailored solution.
Q3: Does the oil lubrication system require an external pump?
A: The standard ZD70 includes an integrated oil pump driven by the input shaft. For remote or high-altitude installations, an optional electric oil pump is available.
Q4: What is the maximum ambient temperature for operation?
A: The gearbox is designed for ambient temperatures from -10°C to +50°C. For extreme environments, we offer optional cooling coils or heaters.
Q5: How do I select the correct gear ratio for my ball mill?
A: The required ratio depends on your mill diameter, speed, and motor RPM. Our technical team can assist in calculating the optimal ratio based on your data – just contact us with your mill specifications.
Q6: Is the gearbox supplied with an oil fill?
A: Yes, we pre-fill the gearbox with ISO VG320 mineral oil during testing. However, for long-term use, you may need to change to a lubricant suitable for your climate and operating conditions.
Q7: What warranty do you offer on the ZD70 gearbox?
A: We provide a standard 12-month warranty from the date of shipment, covering manufacturing defects. Extended warranty options are negotiable.
Q8: Can I get a sample or trial unit before bulk order?
