Solid Shaft Bevel Helical Geared Motor
A high-efficiency, right-angle geared motor built for heavy-duty industrial machinery requiring controlled output speed, exceptionally high torque, and a rigid, positive mechanical connection.
Product Overview
A high-efficiency, right-angle geared motor built for heavy-duty industrial machinery requiring controlled output speed, exceptionally high torque, and a rigid, positive mechanical connection.
Combining two helical gear stages with a precision spiral bevel stage, this drive achieves over 95% mechanical efficiency while changing the power transmission direction by 90°. Fully dimensioned for seamless drop-in compatibility with standard European gear designs (K/KF Series), it delivers a high-reliability, long-service-life drive solution for global procurement and OEM integration.

Product Features
High-Efficiency Gear Train: Two helical stages plus one precision bevel stage optimize energy transmission while changing power flow by 90 degrees.
Carburized & Ground Gears: Gears undergo carburizing heat treatment and high-precision CNC grinding to deliver low noise, high surface hardness, and minimal backlash.
Direct Mechanical Connection: The solid output shaft supports high radial load components directly mounted to the shaft extension.
Flexible Industrial Mounting: Available in foot-mounted (GK) or B5 flange-mounted (GKF) variants to accommodate diverse structural constraints.
Robust Enclosure: IP55 motor protection, Class F insulation, and heavy-duty cast housing ensure reliable operation under continuous duty cycles.
Industrial Applications
Belt & Roller Conveyors: Provides reliable, high-torque right-angle drive setups for material handling lines.
Chain & Bucket Elevators: Handles continuous heavy-duty vertical and horizontal elevation with high starting torque requirements.
Packaging & Bottling Lines: Compact right-angle layout allows motor positioning parallel to conveyor lines, saving aisle space.
Timber & Wood Processing: Fits high-load feeding tables, cutting systems, and log conveyors.
Plastics & Chemical Processing: Suitable for extruders, feeders, and auxiliary mixing machinery.
Steel & Heavy Metallurgy Handling: High-torque frame sizes (GK129–GK189) withstand continuous duty cycle demands.
Hoists, Cranes & Travel Drives: Compatible with electromagnetic brakes for lifting and indexing motions.
Mounting Styles
GK Version (Foot-Mounted): Features a solid shaft and rigid foot casting. Designed for direct bolting onto machine bases, floor mounts, or heavy steel frames. Ideal for driven components requiring direct inline sprocket or coupling setups.
GKF Version (B5 Flange-Mounted): Features a solid shaft with a precision B5 output flange. Perfect for side-mounting directly onto machine walls or enclosures where base mounting space is restricted.
Motor Options & Electrical Configuration
Standard Electricals: 230/400V or 400/690V, 50 Hz / 60 Hz dual-frequency windings.
Motor Pole Numbers: 2-pole, 4-pole (standard), 6-pole, and 8-pole options to suit input speed requirements.
Brake Motor Extensions: DC/AC spring-applied fail-safe electromagnetic brakes with optional manual release levers.
VFD Duty Compatibility: Suitable for variable frequency drive (VFD) operation with reinforced winding insulation options.
Terminal Box Configuration: Top, left, or right mounting positions relative to output shaft direction.
Operating Conditions
Standard Environment: Ambient air temperature -10°C to +40°C, altitude up to 1,000 meters.
Special Duty Modifications: Low-temperature seals/oil (below -10°C), high-temp synthetic oils (above +40°C), tropical moisture protection, explosion-proof ATEX ratings, and anti-corrosion painting available on request.
Quality Control
Every geared motor undergoes rigorous quality verification throughout the production cycle:
Gear Fabrication: Precision gear blank turning -> Hobbing and Shaping -> Gas Carburizing & Hardening -> CNC Tooth Profile Grinding -> CMM Gear Inspection.
Housing & Shaft Processing: CNC machining of cast housing bearing seats -> Shaft turning, keyway milling, and dynamic balancing.
Assembly & Inspection: High-precision bearing fitting -> Gear mesh contact pattern check -> Seal installation -> Lubricant charging.
Final Factory Testing: No-load running test (noise, vibration, and temperature rise verification) -> Motor insulation & electrical safety testing -> Final paint and dimensional inspection.
Frequently Asked Questions
Q: Can I mount a sprocket or V-belt pulley directly onto the solid shaft?
A: Yes. Sprockets, pulleys, gears, and couplings can be mounted directly. However, the radial load exerted by the component must be verified against the specific frame size rating based on pitch diameter and position.
Q: Are CAD files and STEP models available for engineering integration?
A: Yes. 2D dimension drawings and 3D CAD/STEP models are available for all frame sizes to allow system integrators to incorporate the geared motor into equipment design before order placement.
Q: Can motors be supplied with custom voltages, frequencies, or brakes?
A: Yes. Motors can be tailored for global power grids (such as 220V/380V/415V/460V/575V at 50 Hz or 60 Hz). DC fail-safe brakes, forced cooling fans for VFD operation, and explosion-proof (ATEX) options are available upon request.
