Vertical Cycloidal Gearbox is a flange-mounted vertical cycloidal gearbox with coaxial vertical layout. It is engineered for vertical drive systems such as mixing tanks and blenders. Torque is transmitted via multi-tooth cycloidal meshing. Specially optimized vertical sealing prevents oil seepage. This vertical cycloidal gearbox enables easy alignment and is widely used in chemical mixing, food blending and vertical feeding machinery.

Vertical oil seal assembly for leakage prevention
Vertical Cycloidal Gearbox adopts customized oil seals and oil baffle plates for vertical mounting. It counteracts static oil pressure and stops lubricant leakage along the output shaft.
Integrated flange centering reference
Vertical Cycloidal Gearbox uses flange spigot positioning for high coaxiality. It eliminates complicated alignment work when connecting to tank frames and cuts assembly time.
Reinforced bearing set for axial load
Vertical Cycloidal Gearbox is fitted with heavy-duty thrust bearings to withstand downward pulling force from agitator blades and continuous axial load caused by material stirring.

Minimized horizontal footprint
Vertical arrangement saves side space, ideal for tank-top mounting. Multiple agitators can be arranged side by side neatly on production lines.
Smooth forward and reverse switching
Multi-point meshing and low moment of inertia deliver gentle impact during frequent rotation reversal. It reduces shaking and protects agitator blades and tank connections.
Wide media compatibility
Standard cast iron housing and optional stainless steel corrosion-resistant version are available for water-based slurry, mildly corrosive materials and food-grade ingredients.

Q: Is Vertical Cycloidal Gearbox suitable for tank-top agitator installation?
A: Yes. This flange vertical design is developed specifically for tank-top mixers, with downward output shaft to connect agitator blades directly.
Q: Does vertical cycloidal gearbox leak oil more easily than horizontal type?
A: It comes with dedicated oil baffle and seal kits for vertical use. Leakage risk stays low if oil level is filled correctly.
Q: Can Vertical Cycloidal Gearbox be mounted with output shaft facing upward?
A: Yes, but internal lubrication scheme needs adjustment. Please inform us of shaft direction before ordering.
Q: Can it match explosion-proof motors for chemical stirring?
A: Yes. The flange interface works with explosion-proof motors to form a complete ATEX drive assembly.
Q: Are internal spare parts interchangeable between vertical and horizontal cycloidal gearboxes?
A: Transmission parts of the same frame size are interchangeable, but oil seals and baffles are vertical-specific and cannot be swapped directly.
