YZB Explosion-Proof Cycloidal Oil-Cooled Electric Motorized Pulley Drum 0.75-37kW Belt Conveyor Drive Roller

YZB Explosion-Proof Cycloidal Oil-Cooled Electric Motorized Pulley

Product Overview

The YZB series explosion-proof cycloidal oil-cooled electric motorized pulley features cycloidal pinwheel transmission technology, delivering high torque output with exceptionally low noise. Its compact, fully enclosed explosion-proof design makes it the ideal drive solution for narrow mining tunnels, chemical processing lines, and dust-explosive workshops. Compliant with GB3836.1/2 standards and certified for dI and dIIBT4 hazardous environments, the YZB series ensures safe, reliable material handling in the most demanding conditions.

Key Specifications

Key Advantages

• Cycloidal Pinwheel Transmission – Large reduction ratio with superior output torque, outstanding heavy-load climbing capability
• Ultra-Compact Design – Smaller footprint than standard YDB models, perfectly suited for narrow tunnels and confined spaces
• Low-Noise Operation – Minimal gear meshing clearance ensures quiet running with high shock-load tolerance
• Fully Sealed Explosion-Proof Housing – Purpose-built for underground flammable and explosive environments
• Easy Maintenance – Simplified disassembly for oil changes and inspection, eliminating full unit teardown, reducing maintenance costs

Applications

Small-scale underground coal mine belt conveyors, mining feeders, chemical explosion-proof production lines, grain dust explosion-proof conveying, small underground tunneling auxiliary conveyors.

Installation & Operation Notes

• Installation inclination angle ≤5°; angled applications require customized oil chamber design
• Replace oil after first 200 operating hours, then every 1,500 hours thereafter
• Do not strike the drum surface with hard objects — damage to explosion-proof surfaces will void certification
• Maintain moderate belt tension: over-tightening increases bearing wear, under-tightening causes belt slip and motor burnout
• Regularly inspect junction box sealing gaskets to prevent dust and gas infiltration
• For long-term storage, drain all lubricating oil and apply internal anti-rust treatment

Packaging

Small/Medium Power Models: Solid wood pallet + stretch film wrapping, shaft ends protected with foam padding.

High-Power Models: Fully enclosed wooden crate with moisture-proof foam lining, explosion-proof end caps individually protected.

Accessories (backstop, support brackets) packed in separate cartons and secured inside the wooden crate. All packaging marked with explosion-proof, moisture-proof, and upright lifting symbols, with model specifications clearly printed.
