Bevel gear units for efficient right-angle transmission

The bevel gearbox redirects rotation through two cone-shaped gears at an angle of 90 degrees, allowing perpendicular shafts to be used. This allows you to install the motor adjacent to the machine frame which keeps the drive train compact and frees up floor space. ATEK bevel gear units reach an efficiency of up to 97%, so little energy is lost.

Both bevel and worm gearboxes allow changing directions through 90 degrees, but while the former uses cone gears and achieves an efficiency of up to 97% the latter uses the worm principle and experiences greater losses due to friction, resulting in lower efficiency and excessive heat generation.

Thus, select a bevel gearbox to ensure high efficiency and quiet operation. A worm gearbox is chosen for a high reduction ratio and self-locking output. For most dynamic right-angle drives in machine building, a bevel gear unit by ATEK is the best option because it provides maximum efficiency.

You choose a helical bevel gear unit when you need quiet running and higher load capacity. Helical teeth provide smooth meshing and gradual engagement of several teeth. Such simultaneous load distribution increases load capacity, ensuring quiet operation during the constant work cycle. ATEK uses helical teeth in bevel gear units that feature excellent shock load resistance and operate quietly due to gradual engagement.

ATEK bevel gearboxes ensure high precision with low angular backlash due to spiral teeth engagement. This provides precise and consistent positioning and synchronization needed for indexing, exact positioning and dynamic automation. For high-precision indexing requirements, BEGE engineers tailor ATEK bevel gearboxes to ensure exact positioning to the required accuracy.

Bevel gear units are used wherever a motor has to drive a shaft at a right angle. Typical applications include cutters, packaging equipment, conveying mechanisms, poultry cutting, and shipbuilding industry applications. A clear example is a bread slicer, where two bevel gear units drive a pair of centring belts that move the loaf synchronously toward the blades, providing input width regulation. Another is a cheese grating machine, where a bevel gear unit drives a rotating disk. Both illustrate the application in machinery where space savings and precise motion coordination play an important role.

ATEK bevel gear units provide compact design, high efficiency, minimal maintenance, and precise automation capabilities. Key advantages of using ATEK bevel gear units in machinery construction include:

– Compact design: ATEK bevel gearboxes employ right-angle transmission ensuring compact design since motors can be located near machines.

– Efficient power redirection: Rotation redirection at an angle of 90 degrees ensures clean power transfer.

– High efficiency rate: ATEK bevel gearboxes exhibit up to 97% efficiency minimizing losses and generating less heat compared to alternatives.

– Flexible mounting: Single or double-output solid shafts and different hollow-shaft variants in foot, shaft, and flanged outputs accommodate diverse machinery configurations.

– Minimal maintenance: Gears featuring hardened teeth require no regular servicing during conventional usage.

Mini bevel gearboxes offer low torque requirements and small dimensions. The light-weight aluminium L series bevel gearbox operates with 6.0 to 16.0 Nm torque and 6 to 10-mm shaft diameter. It is appropriate for small mechanical processes, sorting and adjusting devices, and precise positioning purposes. Alternatively, consider the V series gearbox with a torque range between 25 to 5,400 Nm and a shaft diameter of 12 to 80 mm. By selecting an appropriate variant, you will keep the machinery build lightweight.

ATEK bevel gear units cover a transmission ratio from 1:1 to 6:1 and a maximum torque from 25 to 5,400 Nm in the standard V Series. The aluminium L Series covers a ratio from 1:1 to 4:1 and a maximum torque of 6.0 to 16.0 Nm for lighter, space-critical applications. Shaft diameters run from 12 to 80 mm on the V Series and 6 to 10 mm on the L Series. This range lets you size a right-angle drive from small positioning tasks up to heavy-duty machine drives.

Hollow shaft bevel gearboxes directly couple with machinery drive shafts. Thereby, they eliminate the installation of additional coupling mechanisms, mounting structures, and alignment procedures. Direct coupling saves installation time, prevents typical causes of bearing wear associated with misalignment, and ensures space savings. During mass production of machines with similar components, direct shaft coupling helps reduce manual labor and spare part inventories.

ATEK bevel gearboxes operate efficiently and maintenance-free during routine exploitation. The spiral-shaped teeth are fabricated from hardened, case-hardened steel featuring a wear-resistant surface layer strengthened with durable internal cores absorbing impact loads. Hard teeth prevent pitting and wearing, avoiding the necessity to adjust and lubricate the gears. For nonstandard operation modes, BEGE engineers suggest optimal variants to ensure durability.
