Product Overview

This document is a detailed catalogue for ATEK's performance-optimized miniature hypoid bevel gearboxes, covering specifications, design, performance data, ordering information, installation guidelines, and global contact details.

1. Miniature Bevel Gearboxes

1.1 General Specifications

• Gear ratios range from 1:1 to 4:1.
• Maximum output torque up to 16 Nm.
• Two housing sizes: 35 mm and 45 mm edge lengths.
• Low-backlash options available, with backlash less than 10 arcmin, some models below 8 arcmin.
• Housing made of aluminium, optionally anodised for corrosion resistance.
• Lifetime lubrication with synthetic lubricants; no maintenance oil changes required.
• Protection class IP54, suitable for dust and splash water exposure.
• Operating temperature range from -10°C to +90°C.

1.2 Construction and Design

• Axles intersect at 90° inside the gearbox.
• High-quality hardened carburised steel spiral toothing ensures high load capacity, smooth operation, and precise transmission.
• Modular system supports multiple construction types (A0 to E0, F0 to K0, branch-off gearboxes) with variations in shaft number, rotation direction, and bearing support.
• All six gearbox sides are machined with threaded holes for flexible mounting; standard mounting code is '9'.
• Installation is flexible; recommended with shafts horizontal (positions 1 and 2). Consultation advised if installation angle exceeds 15° deviation from horizontal.
• Shafts: Fast-rotating shaft (N1) carries bevel pinion; slow-rotating shaft (N2) carries bevel gear.
• Preferred rotation direction is clockwise (CW) from fast shaft end, reducing noise by 1-2 dB(A).

1.3 Performance and Efficiency

• Efficiency depends on speed, torque, installation, sealing, and lubricant; single gear set gearboxes achieve approximately 97% efficiency, multiple gear meshings about 94%.
• Low-backlash versions achieve backlash as low as 8 arcmin, measured under 2% nominal torque on output shaft.
• Optional anodic coating provides corrosion protection.

2. Type L Miniature Bevel Gearboxes

2.1 Features

• Gear ratios from 1:1 to 4:1.
• Maximum output torque up to 16 Nm.
• Two sizes: L 035 (35 mm edge length) and L 045 (45 mm edge length).
• Low-backlash construction with backlash less than 8 arcmin available.
• Aluminium housing.

2.2 Models and Ordering

• Multiple models (A0, B0, C0, D0, E0N, F0, G0, H0, J0, K0N) differ in shaft arrangements and mounting sides.
• Order code includes type, size, gear ratio, model, fixing side, installation position, speed, and design options.

2.3 Performance Data

• Maximum input speed (n1) up to 3000 rpm.
• Output torque (T2N) varies by size and ratio, up to 16 Nm for L 045.
• Power input (P1N) ranges from 0.03 kW to 1.32 kW depending on size and ratio.
• Permissible radial and axial forces on shafts N1 and N2 specified for various speeds and torques.
• Inertia moments and masses detailed; L 035 models weigh approximately 210-290 g, L 045 models 460-700 g.

2.4 Technical Characteristics

• Shafts made of C45 steel with greased ends.
• Shaft fits comply with ISO 6 tolerance and DIN 6885 Sheet 1 for parallel keyways; hollow shafts available with ISO 7 tolerance.
• Radial shaft seal rings made of NBR, form A.
• Standard circumferential backlash less than 30 arcmin; lower backlash options available.
• Protection class IP54 ensures dust and splash water resistance.
• Optional anodic coating for corrosion protection.
• Expected bearing life (L10h) exceeds 15,000 hours.

3. Installation and Mounting

• All six sides machined with threaded mounting holes; standard mounting code '9'.
• Installation positions flexible; recommended shafts horizontal.
• Consultation recommended if installation angle deviates more than 15° from horizontal.

4. Additional Information

• No vent filter included for miniature gearboxes.
• Lubrication is lifetime sealed; no oil changes required.
• Noise reduction achieved by selecting clockwise rotation direction.
• Corrosion protection options include anodic coating with customizable colors.
