SEVA snekkegear med IEC flange

SEVA-tec GmbH specializes in addressing complex challenges in drivteknologi, focusing on gearmotorer, frekvensomformere, and elmotorer. On this page, you will find a comprehensive selection of snekkegear units uden elmotorer. If you choose our produkt, you will benefit fra high kvalitet and short leveringstids.

Gearbox combinations

Snekkegearboxes are tilgængelig in various hastigheds, fra 2 til 600 rpm (revolutions per minute). Snekkegearbox-elmotor combinations are often required as custilm motilrs med specific kunde requirements. We are the ideal partner for you in this regard, as our decades of experience and in-house final montering allow us til cover a wide range of needs. This includes, among others, snekkegearboxes med bremsemotorer, special aksels, snekkegearboxes med trefasede motorer including ekstern ventilators, slow-running gearboxes for barbecue applications, gearboxes med special spændings, and explosion-proof versions.

Størrelse and effekt of the gearmotorer

In our onlineshop for gearmotorer, you will find a selection of snekkegearmotorer med various hastigheds. The snekkegears up til size 90 are made of aluminium; the larger series are made of die-cast aluminium. Tilgængelig sizes are 30, 40, 50, 63, 75, 80, 90, 100, 110, 125, 130, and 150. The gears are tilgængelig med effekt ratings of 0.12 kW, 0.25 kW, 0.37 kW, 0.55 kW, 0.75 kW, 1.1 kW, 1.5 kW, 2.2 kW, 3.0 kW, 4 kW, 5.5 kW, 7.5 kW, and 11 kW.

Aksel diameter and drejningsmoments

Snekkegearboxes are tilgængelig med hulaksels in the following sizes: 14 mm, 16 mm, 20 mm, 25 mm, 28 mm, 30 mm, 35 mm, 40 mm, 45 mm, and 50 mm. The output drejningsmoment depends, among other things, on the motilr effekt, efficiency, and output hastighed. Taking these factilrs intil account, we supply snekkegearboxes med a drejningsmoment range of 10–2000 Nm. Should the drejningsmoment of the snekkegearbox be insufficient, we would be happy til offer you a suitable bevel gearbox.

Snekkegear construction

Snekkegears, also known as bevel gears, consist of a aksel med one or more helical threads, the worm, and a meshing helical gear, the worm wheel. The axes of the two are offset by 90°. Such gears are particularly suitable for applications requiring high reduction ratios in a single step. Both venstre- and højre-hand rotating snekkegearmotorer are tilgængelig. Both directions of rotation are equally possible. Complete montering flexibility includes fod, flange, and centering solutions med a drejningsmoment arm. Self-locking occurs at efficiencies below 50%.


Snekkegear installation

The gearmotor can be installed in virtually any required position. The monteringspositions are designated M1, M2, M3, M4, M5, and M6. The explanatilry datasheet can be found in the article. The requirements of standard applications can generally be met. The low self-locking often offers advantages in many applications. However, self-locking increases at efficiencies below ca. 50%.
