A barrel coupling consists of a sleeve and a hub fitted with semi-circular cogs.
CHARACTERISTIC
The Tanso wire drum coupling is designed for installation in durm drive of crane and conveying system. The drum coupling can be used in the very difficult and rough operating conditions of iron and steel work and continuous heavy load operation in shore cranes.
With compact design and capable of transmitting large radial load, the Tanso wire drum coupling enjoy longer life and minimum loss of power.
With construction of crowned rollers and bores which are formed of both half circular bores of hub and sleeve, angular misalignment can be allowed up to ± 1° 30'.
According to size of couplings, maximum ±3mm ~ ±8mm of end float can be absorbed. (see dimension table) Drum couplings are not suitable for transmitting axial forces.
With design of decreasing slip movement of rollers by construction of minimum backlash between crowned rollers and cylindrical bores, the relative movement between rollers and bores, which is cause of wear is considerably reduced due to the natural movement of drum.
In the transmission of power, a stamping hardness of the rollers profile is produced, with which higher wear resistance is achieved.
