Gear Motor Helical Inline Type

Description

1. Product Overview

Gear Motor Helical Inline Type is a high-performance helical inline gear motor combining a robust helical gear reducer with an integrated electric motor for direct-drive industrial applications. It provides smooth, efficient torque transmission for conveyors, mixers, extruders, pumps, and other continuous-duty equipment where aligned shaft arrangements and compact footprint are required. The product’s key value lies in its high torque density, low noise, and superior mechanical efficiency, enabling lower energy consumption and longer asset life. Strategically, this gear motor addresses rising demand for reliable, energy-efficient power transmission in heavy-duty manufacturing, materials handling, and process industries globally.

2. Key Specifications & Technical Characteristics

• Materials: Housing — high-strength cast iron (EN-GJL-250) or optional epoxy-coated aluminum alloy; gears — case-hardened alloy steel (20CrMnTi or equivalent) with nitriding option; shafts — 42CrMo or equivalent stainless alloy for corrosion resistance.

• Gear type & geometry: Helical gears, inline configuration, module and helix angle optimized for high contact ratio and smooth load sharing.

• Backlash: Standard ≤ 10 arc-min; precision options ≤ 5 arc-min.

• Efficiency: 95%+ (dependent on ratio and size) typical for common ratios; high-efficiency variants available.

• Ratios: Wide ratio range (e.g., 5:1 to 200:1) customizable to application.

• Mounting: IEC/ANSI motor flange interface, foot or flange mounting, flexible input coupling options.

• IP rating: Standard IP55; optional IP66/IP67 for washdown or harsh environments.

• Bearings & seals: Roller bearings on output, heavy-duty labyrinth or lip seals; grease-filled housings with optional grease zerks for re-lubrication.

• Thermal characteristics: Continuous duty S1 rating; ambient temperature -20°C to +40°C standard, extended range options.

• Electrical motor options: IEC frame motors, multiple voltages (380–480 V 3Ø standard), speeds (1,500 / 1,800 / 3,000 rpm) and efficiencies (IE2/IE3/IE4 available); variable frequency drive (VFD) compatible.

• Noise: Low NVH design, typically ≤ 72 dB(A) at rated load (model-dependent).

• Weight & dimensions: Model-specific; compact inline form factor for space-constrained installations.

• Surface finish: Standard phosphate and primer; optional epoxy or polyurethane coatings for corrosion resistance.

• Quality standards: Manufactured to ISO 9001 processes; gear hardness and microstructure tested per applicable DIN/AGMA standards.

• Packaging: Industrial-grade wooden crate or palletized steel frame, moisture barriers, desiccant packs, and anti-corrosion coating for export.

• Shelf life/Storage: Not time-limited when stored dry and protected from corrosion; recommended storage in controlled environment and periodic shaft rotation if stored long-term.

3. Core Industrial Applications

• Material handling and logistics: Drives for conveyors, roller tables, and sorters where inline shaft orientation simplifies line layout and reduces coupling complexity.

• Food, beverage, and packaging: Low-noise, IP-rated variants for conveyor systems, fillers, and packaging lines; washdown-capable coatings and seals available.

• Chemical and process plants: Pumps, agitators, and mixers requiring continuous-duty operation and corrosion-resistant configurations.

• Mining and aggregates: Heavy-duty drives for feeders, crushers, and conveyors that demand high torque, shock tolerance, and long service intervals.

• Plastics and rubber extrusion: Precise speed reduction and high torque for extruders and calendering equipment, improving product consistency.

• Water and wastewater: Reliable pump drives with IP66/IP67 options for outdoor and wet environments.
  Why it outperforms alternatives: Helical gear geometry provides higher contact ratio and smoother torque transmission than spur gears, resulting in lower vibration, reduced noise, improved tooth load distribution, and higher allowable power density. Inline configuration reduces alignment complexity and saves installation space compared with right-angle gearboxes. High-quality materials and heat-treatment deliver superior wear resistance and longer service life, lowering total cost of ownership.

4. Competitive Advantages

• Quality consistency: Controlled heat-treatment and precision grinding ensure repeatable gear mesh characteristics and minimal backlash across production batches.

• Supply reliability: Factory stock for standard sizes, configurable lead times for custom ratios, and multi-location warehousing to support global distribution.

• Logistics capability: Export-ready packaging with shock monitoring options, consolidated LCL/FCL shipping support, and coordinated customs documentation to reduce transit delays.

• Price competitiveness: Tiered pricing for volume buyers, negotiated freight terms for long-term contracts, and value-engineered options to balance CAPEX and lifecycle costs.

• Sustainability: Energy-efficient gearing and motor options (IE3/IE4), reduced material waste through optimized design, and recyclable materials in housing and packaging.

• Technical support: Comprehensive datasheets, 3D CAD models, installation guides, torque-speed curves, maintenance schedules, and application engineering support for sizing and integration.

• Warranty & service: Manufacturer warranty, optional extended service agreements, and spare-parts availability to minimize downtime.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): BULK 20MT.

• Loading capacity: Typical container loading up to 20–22 MT per 20′ container and 24–26 MT per 40′ container depending on model dimensions and packing configuration; actual loading metrics confirmed at order based on SKU mix and packaging.
