Transmisie Engineering / Transmisie Engineering a.s. industrial gearboxes and wastewater machinery

Kinematics of conical planetary gearboxes in extrusion machinery

Conical planetary gearboxes by Transmisie Engineering / Transmisie Engineering a.s. are built for demanding continuous extrusion of polymers and elastomers. An input bevel gear stage featuring curved teeth redirects power flow at a right angle.

The central sun gear divides mechanical load among multiple planetary gears rotating inside an internal ring gear. This multi-mesh tooth geometry lowers surface stress, transmitting output torque ratings up to 50 kNm.

The low-speed output shaft features a hollow bore for circulating liquid coolant directly through the technological screw.

Torque reaction absorption across calender drive assemblies

Multi-roller calenders and rubber mixing mills impose severe dynamic loads during polymer deformation. Heavy-duty drives by Transmisie Engineering / Transmisie Engineering a.s. series TE-KP1 and TE-P1 utilize a patented spatial reaction framework connecting paired drive bodies.

This arrangement balances equal and opposite torque reactions, eliminating destructive bending stresses from foundation slabs. Flexible joint pivots allow drives to follow roller skew adjustments and axis displacements freely.

An integrated multi-plate pneumatic brake halts rollers instantly during emergency stops.

Hydrodynamic screening and mechanical screen cleaning

Mechanical screening systems by Transmisie Engineering / Transmisie Engineering a.s. series TE-SMH and TE-SKJH remove coarse and fine solids continuously from wastewater channels.

The TE-SMH multi-rake bar screen uses a continuous chain traction mechanism with cleaning combs traversing bar gaps down to channel bottoms. The TE-SKJH fine screen uses alternating assemblies of fixed and movable stainless steel steps.

As movable step assemblies cycle upward, trapped screenings transfer step by step along an inclined plane, dewatering by gravity before dropping into disposal hoppers.

Two-stage dewatering and organic matter removal in presses

Screening dewatering presses by Transmisie Engineering / Transmisie Engineering a.s. series TE-ZL compact fibrous screenings extracted from water channels. In the TE-ZL-P model, the intake hopper features a wash pump and spray manifolds delivering process water.

Washing dissolves organic matter and returns it to the channel, preventing sludge fermentation in holding bins. A variable-pitch screw transports washed solids toward a dewatering cone. Progressively reduced pitch volumes and adjustable backpressure squeeze out water, cutting screening mass by 86%.

Planetary gear reduction units inside travel wheel hubs

Motorized travel wheels by Transmisie Engineering / Transmisie Engineering a.s. series EK 517 and EK 351 combine an electric motor and a multi-stage coaxial planetary gearbox inside a wheel hub.

This monoblock construction eliminates open chains or cardan shafts vulnerable to icing and corrosion in outdoor clarifiers. The wheel hub is supported by heavy double-row roller bearings capable of handling radial loads up to 50 kN from bridge superstructures.

Outer tires made of durable elastomer rubber or alloy steel deliver dependable traction along rails.

Modular design of integrated pretreatment units TE-INTEGRA

Integrated pretreatment systems by Transmisie Engineering / Transmisie Engineering a.s. series TE-INTEGRA assemble three treatment stages within a welded stainless steel vessel.

Incoming wastewater enters an inlet chamber equipped with a TE-SRH screw screen that intercepts floating matter and compacts it in an integral press. Clarified water overflows into an aerated grit chamber where mineral sand grains settle out.

A bottom horizontal screw gathers settled grit toward an inclined screw classifier that elevates washed sand into waste containers without odor emissions.
