Manufacturing heritage of Mechanika Maszyn Kacperek and plant infrastructure

Founded in 1982, Polish machine-building enterprise Mechanika Maszyn Andrzej Kacperek has specialized in engineering and building mechanical worm gearboxes MR and screw jacks MRP since 1988.

Over four decades of steady engineering development, this family-owned manufacturing enterprise established a dependable technical foundation for assembly of complex industrial drives.

The company operates two primary branches: a commercial sales office and cylindrical gearbox assembly shop in Warsaw Wola, alongside an engineering design bureau, modern warehouse spaces, and CNC machining centers in Lomianki near Warsaw.

Gear hobbing, grinding, and turning machinery allows agile fabrication of custom shafts, flanges, and transmission gear pairs tailored to industrial requirements.

Design architecture and modular configurations of MR worm gearboxes

KACPEREK MR series worm gear drives are engineered across a broad sizing spectrum spanning MR-28 to MR-200.

The worm wheel bronze rim is produced from premium tin bronze and mounted onto a structural steel hub, while the hardened precision-ground worm shaft delivers dependable meshing geometry and extended continuous runtime in production machinery.

For automated production layouts, the plant supplies specialized versions featuring double-extended input shafts, torque arms, servomotor adapters, and heat-resistant Viton oil seals.

Precision gear units are equipped with a JDLB backlash adjustment mechanism, allowing technicians to deploy these units in multi-axis positioning mechanisms requiring elevated precision.

Mechanical screw jacks in the MRP series for multi-axis lifting motion

KACPEREK MRP mechanical worm-driven screw jacks are engineered for linear travel, multi-point positioning, and synchronous vertical lifting of heavy industrial machinery assemblies.

Models ranging from MRP-0 through MRP-5 span axial thrust ratings from hundreds of kilograms up to multi-ton forces, maintaining smooth linear motion under demanding duty cycles.

Lifting jacks are fitted with precision rolled trapezoidal lead screws offering a self-locking thread pitch that prevents accidental lowering during power outages.

Depending on kinematic machine layouts, units are supplied in rotating screw MRP-SO or traveling screw MRP-SP variants, complete with protective accordion covers and pivoting clevis mounts.

Multi-stage helical and right-angle bevel gear units in HM and HS lines

To support industrial machinery requiring high mechanical efficiency, KACPEREK produces in-line helical gearboxes of the HM and HMZ lines as well as bevel gear units in the S and HS series.

All helical gear pairs undergo deep carburizing and profile flank grinding to ensure quiet tooth meshing and superior contact rigidity under heavy torque loads.

Bevel units with circular spiral teeth ensure smooth mechanical power redirection across 90-degree shaft layouts with minimal operational vibration.

For extended conveyor installations, the plant manufactures hybrid MR+HM drive assemblies, pairing a slow-speed worm reduction stage with an efficient high-speed in-line helical primary gear train.

Drive transmission couplings, precision gear racks, and linkage elements

The mechanical transmission catalog from KACPEREK encompasses flexible shaft couplings, straight and helical gear racks, spur gears, and roller chain sprockets.

All components are machined on multi-axis turning and milling centers utilizing alloy engineering steels with thermal surface hardening along active tooth engagement profiles.

Polyurethane elastomeric inserts within jaw couplings absorb dynamic torsional shock pulses and reliably accommodate angular and radial shaft misalignments.

Precision splined adapters and clamping sleeves ensure positive torque transmission without slip during frequent bidirectional reversing machine cycles.

Nameplate gear ratio identification and drive unit engineering selection

When submitting an engineering request for replacing a worn KACPEREK gearmotor, the primary reference parameter is the gear ratio, marked upon the metal rating nameplate with the letter i.

If the nameplate is illegible or damaged, the ratio is calculated by dividing the total tooth count of the bronze wheel z2 by the number of thread starts on the worm z1.

Company application engineers provide selection support based upon center-to-center distance, hollow bore diameter, motor mounting flange dimensions, and required output shaft speed.

Complete drive configurations include selection of synthetic lubricants engineered for sub-zero ambient temperatures or hygienic food processing conveyors.
