Mounting to customer shaft without shaft shoulder

  1. Clean the customer shaft [1] and the inside of the hollow shaft [2]. Make sure that all grease and oil residues are removed.
  2. Mount the stop ring [3] and the bushing [4] on the customer shaft.
  3. Apply NOCO-Paste onto the bushing [4] and spread it thoroughly.
  4. Push the gear unit [5] onto the customer shaft.
  1. Fasten the gear unit on the mounting surface (do not tighten the screws).
  2. Slide the bushing [4} into the gear unit [5] up to the stop.
  3. Secure the bushing with the stop ring [3]. Tighten the stop ring [3] to the bushing with the tightening torque listed in the following table.

  1. CAUTION! The shrink disk can slip when not tightened. Potential risk of crushing due to falling parts. Secure the shrink disk against slipping.NOTICE! Tightening the locking screws without first installing a shaft may result in the hollow shaft being deformed. Possible damage to property. Never tighten the screws without the shaft installed.Make sure that all locking screws are loosened and slide the shrink disk [6] onto the hollow shaft [2].
  2. Position the inner ring [6c] of the shrink disk to dimension A.

  1. Slide the counter bushing [7] onto the customer shaft and into the hollow shaft [2].
  2. Tap lightly on the flange of the counter bushing [7] to ensure that the bushing is fitted securely in the hollow shaft.
  3. Make sure that the customer shaft is seated in the counter bushing.
  4. Tighten the locking screws [6a] of the shrink disk only manually. Align the taper (outer ring) [6b] parallel to the taper bushing (inner ring) [6c].

INFORMATION

If the taper (outer ring) and the taper bushing (inner ring) cannot be aligned on the face that holds the screws, disassemble the shrink disk again and carefully clean/lubricate it sufficiently.
  1. Tighten the locking screws clockwise (not in diametrically opposite sequence) by 1/4 revolution. Work around the ring in several stages, evenly tighten the locking screws by a quarter turn each until the taper (outer ring) [6b] and the taper bushing (inner ring) [6c] align on the face that holds the screws.
  2. The remaining gap between stop ring and hollow shaft end, as well as mating bushing and hollow shaft end must be > 0 mm.
  3. Tighten the retaining screws of the gear unit with the specified tightening torque. Refer to the operating instructions of the gear unit for the tightening torques.
