IMPORTANT: In any applications of Cone Drive Products where breakage, damage, disconnection,
any other malfunction of any drive train component, or excessive wear could result in personal
injury or property damage, a fail safe device capable of stopping and holding the load in the event of
such an occurrence must be incorporated after the drive train.
Lubrication and Maintenance Notes:
- Type of Oil. For Cone Drive double enveloping worm gear speed reducers use the lubricant information on the nameplate and this Approved List of Lubricants to select the proper lubricant. For Cone Drive gear sets used in other assemblies, use this document to select a lubricant. Contact Cone Drive if in doubt.
- Ambient Temperature. The lubricants in this list are for use in an ambient temperature range of approximately 15°F to 125°F with the low end of the range depending on the pour point of the specific oil used. The lubricant Pour Point must be at least 5°C (9°F) less than the minimum startup temperature expected. If the ambient temperature will be below or above this range please contact Cone Drive for specific recommendations on proper lubricant as well as proper oil seal and shim materials.
- Sludge. It is necessary that the oil be clean and free from sludge at all times to obtain long life from the gear unit. Sludge in gear units may be caused by excessive heat, from dust and dirt and other contaminates and by the presence of moisture or chemical fumes. Therefore, every precaution should be taken to prevent water and foreign particles from entering the gear case.
- Oil Change. If an approved synthetic lubricant is used, it should be changed after 5000 hours of operation or once per year, whichever occurs first. If a recommended steam cylinder oil is used, the change interval should be after 2500 hours of operation or every six months, whichever occurs first. These change intervals are recommended for units operating under favorable conditions. Where operating conditions are severe, such as a rapid rise and fall in temperature of the gear case with accompanied sweating of the inside wall and resulting formation of sludge, or where operation is in moist or dusty atmospheres, or in the presence of chemical fumes or extended running at sump temperatures in excess of 180°F, it may be necessary to change the oil at intervals of one to three months. It is recommended a sampling program be established with your lubricant manufacturer where reducers are exposed to the severe operating conditions, mentioned above.
- Oil Level. Oil level should always be checked with the unit stopped.
- Extreme Pressure (EP) Lubricants. Extreme Pressure (EP) lubricants or cylinder oils with sulfur-phosphorus additives are not acceptable and should not be used with worm gearing.
- High Speed Applications. Double enveloping worm gears operating at a sliding velocity in excess of 10 m/s (2,000 ft/min) may require force-feed lubrication. For force feed lubrication recommendations, contact Cone Drive Engineering.
- Greased Bearings. High quality lithium base NLGI #2 or NLGI #3 grease should be applied to fittings at normal maintenance intervals depending on duty cycle. Only bearings requiring added grease will have fittings.
