Precision Belting Design and Manufacture

Drive Details

Because of the broad scope of endless belt application and the need for specific drive properties, a complete job description can not be overemphasized when requesting information.

Listed below, in outline form, are major drive categories and details essential to job description. This outline can serve as a guide in discussing your requirements with our representatives or be a useful tool in phrasing written requests for information.


TYPE OF DRIVE (specify which)

  1. Individual belt drive.

  2. Group belt drive. (Assumes more than one belt on common shafts but having individual take-up.)
    a) Specify number of belts in group.
    b) Describe method of belt guidance.
  3. Belt set drive. (Assumes more than one belt on common shafts but having common take-up or no take-up.)
    a) Specify number of belts in set.
    b) Describe method of belt guidance.

NOTE: Indicate approximate belt tension allowable by machine design. Information essential when belts run in sets.

DRIVE ARRANGEMENT (specify which)

  1. Open
  2. Serpentine
  3. Crossed
 

DRIVE DETAILS (specify all)

  1. Pulley diameters.
    a) Indicate drive and driven.
  2. Size of pulley crown.
  3. Pulley RPM (with specific diameter) or feet per minute belt speed.
  4. Approximate horsepower.

NOTE: For fractional horsepower, list torque to be delivered to driven pulley.

LENGTH ADJUSTMENT (specify which)

  1. Length adjustment available.
    a) Specify actual drive circumference with take-up in minimum length position and in maximum length position.
  2. Fixed centers having no adjustment.
    a) Specify actual drive circumference.

WIDTH ACCOMMODATION (specify which)

  1. Open pulley.
    a) Width of pulley face.
  2. Flanged pulley.
    a) Measurement between flanges.

SPECIFIC PROPERTIES

While the preceding has dealt primarily with basic mechanical design, complete job description should include a brief summary of work to be accomplished with consideration being given to desired specific properties. In broad scope, the following should be reviewed.

  1. Positive drive.
  2. Clutch type action with slippage.
  3. Any mechanical reason for specific belt thickness.
  4. Food handling.
  5. Special antistatic requirements.
  6. Special non-marking requirements.
  7. Abnormal oil or chemical resistance properties.
  8. Abnormal temperature conditions.
    (List specifically with duration of temperature.)
  9. Unusual drive hazards or peculiar belt properties.
