Taper Lock Bushes

SSTmachinery taper Lock bushes are flangeless for clean, compact application.

They are engineered with an 8° taper and a flush-mounted design with no protruding parts providing secure locking and elimination of wobble.

In addition, Taper lock bushes are available with an optional integral key in popular sizes for a more precise fit.

The Taper lock bushes system keeps the sprocket hubs narrow so the length-thru-bore dimension is less than ever before. The left-justified hub design allows shaft mounting close to bearings, keeping the center of load dimension small while preventing issues with high overhung loads.

Taper-Lock bushings are split through the flange and gradual taper to provide a true clamp fit on the shaft that is the equivalent of a shrink fit.

The outer cone surface of the cone sleeve is matched with the inner cone surface of the belt pulley. To fit the cone sleeve into the belt pulley, an opening is required on the cone sleeve. The opening consists of a blind groove and a through groove that connect the central hole. The through groove and the blind groove are set opposite each other, and the groove widths of the two grooves are equal. Because the opening can be bent, the cone sleeve can be shrunk slightly by extruding it radially, so that the cone sleeve can enter the belt pulley correctly, so as to facilitate the installation of the cone sleeve and the belt pulley. The saw blade with reciprocating linear motion is used for slotting to cut the taper sleeve. The specific cutting process is: first fix the tooling of the taper sleeve, then feed and cut the upper material of the taper sleeve downward to form a through groove, then the saw blade enters the central hole, and finally the saw blade cuts the lower material of the taper sleeve to form a blind groove. After cutting, the saw blade resets to achieve the processing of the opening. However, the saw blade has no travel in the central hole, which delays the cutting of the blind groove and further reduces the efficiency of machining the opening. In addition, the speed of the saw blade moving in a straight line is always the same, while the depth of the through groove is greater than the depth of the blind groove, and the consistent speed will significantly reduce the cutting speed, further reducing the efficiency of processing the opening.
