Characteristics

High torque

Application economically advantageous

Limited installation time

Excellent shaft-hub perpendicularity

Installation

Carefully clean the hub and shaft contact surfaces and apply a light oil film. Industrial slide the locking assembly into the hub bore, insert the shaft and tighten gradually and regularly in crossed sequence all screws to reach the tightening torque Ms as indicated in the table.

The values Mt and F ass indicated in the table are valid only in case of oil installation. Do not use any oil with molibdenum bisulphide or high pressure additives and not grease. Above substances notably reduce the friction coefficient.

Dismantling

Loosen the clamping screws. Insert the screws into the dismantling threading and tighten gradually and regularly in crossed sequence until the back cone is released. If the element is to be reused, relubricate both screws and threads.

Tolerances, surface finish

A good surface finish by the equipment tool is sufficient. Maximum allowable surface finish:

Rt max 16 Mm (Ra 3 Mm - Rz 13 Mm)

Maximum permissible tolerances: h8 for shaft H8 for hub

Axial movement

TLK 130: during screws tightening the hub has a slight axial movement with respect to the shaft.

TLK 131: during screws tightening the hub has no axial movement with respect to the shaft.

DM hub calculation

The pressure Pn in the hub can be compared to the inside pressure on a thick hollow cylinder.

For DM calculation see page 38.

NOTE: it is possible to reduce the screws tightening torque down to 60% of the values indicated in above table; as a result Mt, F ass, Pw, Pn are reduced proportionally.
