Product Overview: The "All-in-One" Drive Solution
Traditional conveyor drives consist of an external motor, a gearbox, a coupling, and a pulley, all mounted on a heavy base frame. This takes up space and creates safety hazards with exposed rotating shafts.
The Kunwei Electric Pulley (TDY75 / DY1 Series) puts everything inside the steel drum.
- Space Saving: No external motor protruding from the side. Ideal for portable conveyors or tunnels.
- Safety: No external chains or couplings to catch workers' clothing.
- Durability: The internal motor runs in a sealed oil bath, protecting it 100% from outside dust, sand, and rain.
Cooling & Lubrication (Oil-Cooled Type)
Our standard Electric Pulleys use Direct Oil Cooling. The drum is partially filled with industrial gear oil. As the drum rotates:
- The oil lubricates the gears and bearings continuously.
- The oil absorbs heat from the motor and transfers it to the drum shell, which is then cooled by the conveyor belt. Note: This design means the pulley effectively cools itself while running.
Technical Specifications
- Standard Series: TDY75 (Oil Cooled) / DY1 (Hard Gear Surface).
- Power Range: 1.5 kW to 55 kW.
- Belt Speed: 0.8 m/s to 4.0 m/s.
- Diameters: 320mm, 400mm, 500mm, 630mm, 800mm, 1000mm.
Customization Options
- Rubber Lagging: We highly recommend adding Diamond Pattern Rubber Lagging to the steel shell. This increases friction, prevents belt slippage in wet conditions, and sheds water.
- Backstop (Anti-Runback): For inclined conveyors, we install an internal mechanical backstop to prevent the belt from rolling backward when power is cut.
- Explosion Proof: For coal mines or grain elevators, we offer Ex-rated motors inside the drum.
Installation & Maintenance
- Installation: Simply mount the two shaft ends into the conveyor frame blocks and wire the terminal box. No laser alignment of couplings is needed.
- Oil Change: This is the only maintenance required.
- First change: After 300 hours of operation (Break-in period).
- Regular change: Every 6 months.
- Tip: There are two drain/fill plugs on the side of the drum. Rotate the drum so one is at the bottom to drain.
FAQ
Q: Can I use a VFD (Inverter) with this pulley?
A: Yes, but please inform us before ordering. We need to use "Inverter-Duty" insulation for the internal motor to prevent overheating at low speeds.
Q: What happens if the oil leaks?
A: We use high-quality Double Lip Oil Seals. However, if you see oil leakage, stop the machine. Running without oil will burn the motor stators quickly.
