MKEL Right-Angle Gearboxes

MKEL right-angle gearboxes use spiral bevel gearing with a projecting output shaft and a round output-side mounting face. Compare the catalog sizes at one defined ratio, then check the exact output connection and motor adapter.

MKEL Series / Gearboxes

Start with the output connection.

Match the output arrangement to the machine before comparing ratings. The catalog drawings show a projecting output shaft and a round output-side mounting face. The series uses ball bearings.

The details that matter.

Output arrangement and ratio

2-stage

Lower-ratio configurations

The performance tables and dimensional drawings use the stage label shown here. Select one listed ratio and the required shaft style.

Listed ratios: 3:1 · 4:1 · 5:1 · 6:1 · 7:1 · 8:1 · 9:1 · 10:1
Output styles: K: keyed shaft · S: smooth shaft

3-stage

Higher-ratio configurations

The catalog lists discrete ratios from 15:1 through 100:1. Use the matching performance row and 3-stage drawing; weight and motor-side dimensions can change.

Output styles: K: keyed shaft · S: smooth shaft

Select the 2-stage or 3-stage configuration and its matching drawing. Size labels are not complete ordering part numbers; confirm the output style, backlash and motor mounting code with Mach.

Compare one defined operating point.

This snapshot compares the 7:1 ratio across the catalog sizes. All values below use the performance-table configuration labeled 2 Stage. Consult the full catalog for another ratio or the 3-stage group.

Nominal torque is the catalog 7:1, 2-stage value at the listed nominal input speed. Its footnote states 20,000 hours of service life at nominal input speed; this is a catalog condition, not a guarantee for every operating cycle. Nominal input speed is defined as maximum average input speed. Weight may vary slightly by model. Maximum and emergency-stop torque have separate limits.

Your application

Give Mach the operating point and interfaces.

Send the complete requirements so Mach can check the ratio, gearbox size, motor adapter and output connection together.

Torque, speed and duty
Provide running torque, acceleration and stopping loads, input and output speeds, operating cycle, required service life and ambient conditions. Identify reversing or shock events so their limits can be checked separately.
Output loads and accuracy
Specify radial and axial forces, where they act, any overturning moment and the backlash requirement. Catalog permitted loads have separate load-position and zero-cross-load conditions; ask Mach to check the combined loads in the actual assembly.
Motor and mechanical fit
Send the motor model and drawing with shaft diameter and length, pilot, flange and bolt pattern. Include the output connection and available space. The catalog notes that length varies with motor and that a bushing adapts to the motor shaft; confirm the supplied adapter and exact drawing.
