Abstract: A roller grill includes a housing structure adapted to support the roller grill; a plurality of tubes having outer surfaces adapted to transfer heat to a pre-cooked food product; a plurality of rollers mounted in a row, each roller mounted on an end of a corresponding tube and including a plurality of detented projections extending from a circumferential surface of the roller; and a drive assembly. The drive assembly includes a continuous looped surface coupled to a motor shaft and contactingly engaged with the detented projections of the plurality of rollers. The roller grill further includes a protrusion mounted to the housing structure and in contacting engagement with the continuous looped surface, such that the continuous looped surface is contactingly engaged with at least two detented projections of each roller of the plurality of rollers mounted in the row.

Abstract: A roller grill for heating a pre-cooked food product includes a housing structure adapted to support the roller grill; a plurality of tubes having outer surfaces adapted to transfer heat to a pre-cooked food product; a plurality of tube gears, at least one tube gear mounted on an end of a corresponding tube; and a drive assembly. The drive assembly includes a motor having a shaft adapted to rotate at a first rotational speed; and a plurality of idler gears mounted to a portion of the housing structure and contactingly engaged with the plurality of tube gears, the idler gears adapted to transfer a rotational power from the motor to the plurality of tube gears at a second rotational speed.

Abstract: A roller grill for heating a pre-cooked food product includes a plurality of tubes having outer surfaces adapted to transfer heat to the pre-cooked food product; a plurality of spur gears, each spur gear mounted on an end of a corresponding tube; and a drive assembly. The drive assembly includes a motor; a timing pulley coupled to a shaft having a plurality of worm gears mounted thereon; and a timing belt coupled to the motor and the timing pulley and adapted to transfer rotary motion generated by the motor into rotary motion of the tubes through contacting engagement of the worm gears with the spur gears.

Abstract: A roller grill for heating a pre-cooked food product includes a housing structure adapted to support the roller grill; a plurality of tubes having outer surfaces adapted to transfer heat to the pre-cooked food product; a plurality of non-metallic gears, each non-metallic gear mounted on an end of a corresponding tube; a motor including a motor shaft and adapted to generate a rotational power through the motor shaft at a first rotational speed; and a drive sub-assembly adapted to transfer the rotational power from the shaft to the plurality of non-metallic gears at a second rotational speed.
