Taper Bush

TB case

                Type A                                                 Type B

        Cases 1008 - 3030                             Cases 3525 - 5050 
 

You cannot choose between type A and B (2 or 3 clamping screws). Shape of the housing
is predetermined according to its size.
 

Construction, design, marking

Each TB pulley or other element clamped by a TB bushing contains in
TB bushing number in its marking. Each bushing no. is
is produced in variants for different shaft diameters. The designation of the specific
clamping sleeve therefore always contains its number + shaft diameter, on
to which the bushing can be fitted. For example TB 1210 - 20.
 

Assembly and disassembly instructions for TB clamping sleeves

Assembly

1. Before assembly, all seating surfaces must be cleaned and degreased.
   surfaces and threads.
2. Lubricate the threads, insert the bushing into the pulley and seat it in the
   correct position.
3. Screw the screws lightly into the resulting pressed holes.
4. Now fit the whole assembly onto the shaft so that the pen fits easily into the
   into the groove.
5. Tighten the bolts to the prescribed tightening torque.
6. After a short period of operation (0.5-1 hour), recheck the tightening.
    

Disassembly

1. Unscrew the screws from the mounting holes and screw them into the
   the mounting holes.
2. Simultaneously tighten the screws to release the pulley from the housing.
3. Pull the housing off the shaft.

Intermediate rings TB

The intermediate ring allows you to clamp components with a conventional cylindrical
bore using a TB tapered clamping sleeve.
 

Installation

For assembly, the intermediate ring is fitted onto the TB bushing and into the pressed
mounting screws of the bushing are screwed lightly into the machined holes. This set of
is inserted into the cylindrical hub of the clamping element and at the same time mounted on the
the shaft so that the locking lips of both the bushing and the intermediate ring slide freely into the
grooves. By alternately tightening the mounting screws, the sleeve is pressed into
into the intermediate ring. The resulting radial forces hold the whole assembly firmly on the shaft.
