An industrial gearbox is an enclosed system that transmits mechanical energy to an output device, for an example a motor. A gearbox can be used to modify the ratio of speed, torque and rate of rotation sent to the output device. Gearboxes have a wide range of applications and come in 4 main varieties.
This type of Gearbox is popular in cutting edge technologies like Robotics and 3D printing. A Planetary Gearbox has a central Sun Gear is surrounded by three of four Planet Gears. These are all held together through an outer ring gear with internal teeth. This design spreads the power equally through the gears and enables a Planetary Gear System to achieve a high torque in a small space. Planetary Gear Boxes are known for their high endurance and accuracy.
Worm Gearboxes are most often used to drive heavy duty operations. This type of gear incorporates a large diameter worm (or screw) which meshes with the teeth on the peripheral area of the gear. This arrangement allows the user to determine rotational speed and allows a higher torque to be transmitted. Worm gears are used to transmit power at 90 degrees and applications include elevators and conveyor belts.
Helical Gearboxes are compact in size and use a low amount of power. The teeth on a Helical Gear are cut to an angle to the face of the gear and so during rotation, when two of the teeth start to engage the contact is gradual. Starting at one end of the tooth and maintaining contact as the gear rotates into full engagement. This arrangement means the gearbox will run more smoothly and can accommodate high load angles. It also means that a Helical Gearbox can transmit motion between parallel or right angles shafts.
Bevel Gears have curbed teeth located on cone shaped surfaces which close to the rim of the unit. They are used to provide rotary motions between non-parallel shafts and have a wide range of applications including in Rolling Stock and the mining industry.
What We Provide
Bronte Precision produce Internal and External Spur and Helical Gears as well as Double Helical Gears. We often work on gears for industrial applications which can be large in size, up to 1450mm in diameter. We have also machine many gearbox cases, often working from cast components as well as drive, idle and splined shafts. Send through your RFQ today for a no obligation quote.
