Description

    BACKGROUND OF THE INVENTION
  • Present methods of connecting speed reducers to conveyor systems are cost and labor intensive. The cumbersome existing methods for mounting speed reducers on conveyors require extensive amounts of time and labor for installation and maintenance. A traditional drive system mounting method can take experienced technicians hours to install. The costs of installation and maintenance add up quickly when considering the miles of conveyor lines in any commercial warehouse. Furthermore, time and manpower is lost on paperwork, phone calls and receiving time associated with sourcing multiple components.
  • These existing systems generally include a reducer, two mounted bearings, a motor, two sprockets, a chain, a chain guard and mounting brackets. Often, systems are incompatible with certain parts or components because the systems utilize various bolt mounted bearings. Common problems associated with existing conveyor systems are related to shock loads. Shock loads can cause chain stretch, sprocket changeovers and other damaging effects.
  • Needs exist for simpler conveyor flange adaptors with fewer components that are easier and quicker to install.
    • SUMMARY OF THE INVENTION
  • The present invention is an innovative one-piece conveyor flange designed for hollow bore, direct drive configurations. A dual flange casting has two opposite flanges machined and drilled to attach between a mounting plate on an electric motor speed reducer housing and a similar mounting plate on a conveyor drive frame. The adapter has a large central axial opening between the two parallel plates, through which a rotating drive shaft extends. The adapter is bolted in place between the speed reducer housing and the conveyor drive frame. The flange adapter has a base mounted on the speed reducer. The outer cruciform flange, with six drilled holes, slots or enclosed scalloped slots, mounts directly on the conveyor frame with two or four bolt connections. Rubber grommets may pass through the enclosed scalloped slots. The conveyor drive shaft fits through the opening and connects to gears inside the reducer. Alternatively, the reducer has an output shaft that extends through the opening and directly connects to the conveyor drive.
  • The conveyor flange drive speed reducer adapter of the present invention provides a direct conveyor drive and eliminates bearing flanges, drive sprockets, driven sprockets, roller chains, chain guards and reducer mounting brackets. The present invention also reduces the space and cost associated with installing and maintaining such devices.
  • The conveyor flange of the present invention decreases maintenance assembly and disassembly time by approximately 75% due to the reduction in components and the decrease in complexity. The present invention also reduces the overall cost of a power transmission drive by about 40%. The reduction in components also reduces the amount of space required in a plant for the systems. The present invention is compatible with existing systems and may be used with both two and four bolt mountings.
