Whether you need replacement gearing, a custom engineered set of gearing, or a complete gearbox, you will benefit from BSEW’s expertise in the design and manufacturing of industrial gearing.
BSEW has a long history in providing power transmission solutions to steel industry. Over the decades, we have worked in co-operation with major steel plants in the business and are able to meet high quality demands and documentation requirements. You get quality, longest lasting industrial gearing for any application.
Today, along with the other products we have developed, we continue to focus on providing custom gears, made to your drawing specifications, or reverse engineered. We can also supply custom gears redesigned to meet your increasing demands.
Advantages of BSEW Custom Gears and Replacement Gearing:
- High quality forged steel and alloy
- Well head treated gear profiles are grinded
- Profile grinded gears
- Capacity is up to 30 module and 4000 mm diameter
- Material and heat treatment selected to provide the optimum performance in your specific application
- Carburized gearing capable of providing 30-50% more torque than through hardened gearing
- A deep, uniformly carburized case across the entire profile and root provides superior wear and strength properties
- Reverse engineering, design upgrade and failure analysis services are available to assure that your custom gearing requirements are satisfied.
Spur Gears
- Gears having cylindrical pitch surfaces are called cylindrical gears. Spur gears belong to the parallel shaft gear group and are cylindrical gears with a tooth line which is straight and parallel to the shaft. Spur gears are the most widely used gears that can achieve high accuracy with relatively easy production processes. They have the characteristic of having no load in the axial direction (thrust load). The larger of the meshing pair is called the gear and smaller is called the pinion.
- To meet your requirements BSEW Spur Gears are made in a variety of materials, configurations, modules, and numbers of teeth. BSEW offers Spur Gears that allow secondary operations to be performed on the bores, shafts, outside diameters, keyways and set screws. Spur Gears that are fine pitch (Modules 0.5, 0.8 & 1), medium pitch (Modules 1.5, 2 & 2.5) and coarse pitch (Modules 3, 4, 5, 6, 8 & 10).
Helical Gears
1. Helical gears are used with parallel shafts like spur gears and are cylindrical gears with winding tooth lines. They have better teeth meshing than spur gears and have superior quietness and can transmit higher loads, making them suitable for high speed applications. When using helical gears, they create thrust force in the axial direction, necessitating the use of thrust bearings. Helical gears come with right hand and left-hand twist requiring opposite hand gears for a meshing pair.
2. BSEW helical gears are quiet, compact, and economical. They are suitable wherever you require high-speed rotation including in machine tools, speed reducers and other industrial machinery.Bevel Gears
1. Bevel gears have a cone shaped appearance and are used to transmit force between two shafts which intersect at one point(intersecting shafts). A bevel gear has a cone as its pitch surface and its teeth are cut along the cone
2. BSEW bevel gears are available in two types, spiral and straight tooth, in gear ratios of 1.5 through 5, and are offered in a large variety of modules, numbers of teeth, materials and styles.Worm Gears
- A screw shape cut on a shaft is the worm, the mating gear is the worm wheel, and together on non-intersecting shafts is called a worm gear. Worms and worm wheels are not limited to cylindrical shapes. Due to the sliding contact of the gear surfaces, it is necessary to reduce friction. For this reason, generally a hard material is used for the worm, and a soft material is used for worm wheel. Even though the efficiency is low due to the sliding contact, the rotation is smooth and quiet. When the lead angle of the worm is small, it creates a self-locking feature
2. The simplest way to obtain a large speed reduction with high torque in a compact space is with worm gear drives. BSEW manufacturers worms and worm wheels are available in modules 0.5 to 6 and in speed ratios of 1/10 to 1/120, made in a variety of materials and styles.
Internal Gears
- Internal gears have teeth cut on the inside of cylinders or cones and are paired with external gears. The main use of internal gears is for planetary gear drives and gear type shaft couplings. There are limitations in the number of teeth differences between internal and external gears due to involute interference, trochoid interference, and trimming problems. The rotational directions of the internal and external gears in mesh are the same while they are opposite when two external gears are in mesh
- BSEW internal gears are offered in modules 0.5 to 3 in 50 to 200 teeth. They can be used in many applications including planetary gear drives
