BMG’s comprehensive range of Tsubaki power transmission components now includes pin gear drive units that replace conventional gear rack systems. “The new Tsubaki standard steel series and the stainless steel S series units are a combination of a pin structure wheel/rack and a sprocket with a special high strength tooth profile that engages continually and smoothly with the rollers. This feature allows greater freedom when designing rotating or linear drive units,” says Scott Larson, general manager for BMG’s chain division. “Another advantage is the high pin wheel/rack balance, which offers greater transmission torque.”
These units, which have a separable segment design to ensure easy installation, can be used in large scale equipment by increasing the number of segments required for each application. In a rotational drive, the pin wheel diameter is extended by increasing the number of pins and in a linear drive, the pin rack length is determined by the number of pins used.
They can also be surface coated for additional protection and teeth are hardened to improve strength and wear resistance. In the standard series, lock type pin gears have a friction fastening mechanism for easy phase adjustment. Units, with only two thirds or half the standard amount of backlash are also available. This feature improves stopping accuracy where necessary. Typical applications of these pin gear drive units include environmental sanitation equipment, railroad turntables, welding rollovers and revolving door mechanisms. They are also used in casting lines, rotary kilns, drives for large transporters, handling robots and pallet changers on machine tools.
