Service, Motors, Bearings | Greenheck Fan 47555 specification

Motors

Motor maintenance is generally limited to cleaning and lubrication. Cleaning should be limited to exterior surfaces only. Removing dust and grease buildup on the motor housing assists proper motor cooling. Never wash-down motor with high pressure spray.

Greasing of motors is only intended when fittings are provided. Many fractional motors are permanently lubricated for life and require no further lubrication. Motors supplied with grease fittings should be greased in accordance with the manufacturer’s recommendations. When motor temperature does not exceed 104ºF (40ºC), the grease should be replaced after 2000 hours of running time.

Direct drive systems have extended grease lines to lubricate the motor without removal of any guarding.

Bearings

The bearings for Greenheck fans are carefully selected to match the maximum load and operating conditions of the specific class, arrangement, and fan size. The instructions provided in this manual and those provided by the bearing manufacturer will minimize any bearing problems. Bearings are the most critical moving part of the fan, therefore, special care is required when mounting them on the unit and maintaining them.

Greenheck Fan Corporation recommends bearings to be relubricated quarterly at a minimum. All Vektor‑CD fans use Mobil Mobilith SHC 100 synthetic grease conforming to NCGI Grade 2. Never mix greases made with different bases. This will cause a breakdown of the grease and possible failure of the bearing. For specific information, contact the factory representative or the fan system submittals.

V-Belt Drives

The V-belt drive components, when supplied by Greenheck Fan Corporation, have been carefully selected for this unit’s specific operating condition. Caution: Changing V-belt drive components could result in unsafe operating conditions which may cause personal injury or failure of the following components:

•Fan Shaft

•Fan Wheel

•Bearings

•V-belt

•Motor

V-Belt Drive Installation — Belt Drive

1.Remove the protective coating from the end of the fan shaft using mineral spirits or another similar solvent. Check to ensure that the shaft is free of nicks and burrs.

2.Slide sheaves on shafts - do not drive sheaves on as this may result in bearing damage.

3.Align fan and motor sheaves with a straight-edge or string and tighten.

4.Place belts over sheaves. Do not pry or force belts, as this could result in damage to the cords in the belts.

5.Adjust the tension until the belts appear snug. Run the unit for a few minutes and allow the belts to “set” properly.

6.With the fan off, adjust the belt tension by moving the motor pivot plate. When in operation, the tight side of the belts should be in a straight line from sheave to sheave with a slight bow on the slack side.
