Product Description

Elevator geared traction machine SN-TMYJ220
 

The Geared Traction Machine is a traditional yet reliable drive system used in elevator applications, particularly suited for low- to mid-rise buildings with moderate speed requirements. Unlike gearless systems, it incorporates a gearbox to amplify torque, making it a cost-effective solution for many commercial and residential applications.

1. Structure and Key Components

• Electric Motor: Typically an AC or DC motor providing rotational power to the system.

• Gearbox: Reduces motor speed while increasing torque through a worm-and-wheel or helical gear arrangement.

• Traction Sheave: Drives the elevator ropes (steel cables) to move the cab and counterweight.

• Braking System: Includes mechanical brakes that engage during stops or emergencies.

• Control System: Governs acceleration, deceleration, and floor-leveling precision.

2. Working Principle

The motor rotates at high speed, and the gearbox reduces this speed while multiplying torque. The output shaft then turns the traction sheave, which moves the elevator via friction between the ropes and the sheave grooves. The gearbox allows smaller, less expensive motors to handle heavier loads effectively.

3. Advantages

• Cost-Effective: Lower initial cost compared to gearless machines.

• High Torque Output: Suitable for heavy loads (e.g., freight elevators).

• Proven Reliability: Long-standing technology with well-understood maintenance needs.

4. Limitations

• Lower Efficiency: Gear friction causes energy losses (~70-80% efficiency).

• Higher Maintenance: Requires regular lubrication and gear inspections.

• Noisier Operation: Gear engagement produces more vibration and sound.

5. Applications

• Low- to mid-speed elevators (≤2.5 m/s).

• Budget-conscious projects where gearless systems are unnecessary.

6. Maintenance Requirements

• Frequent gear oil changes.

• Bearing and brake inspections.

• Rope tension adjustments.

FAQ
1. Are the elevator wire ropes durable?
The elevator wire rope has special provisions and requirements. Configuration is not only for wire rope and rated load, but also considered the size of the traction, as a result, the tensile strength of wire rope is greater than the weight of the lift. The safety factor is equipped with more than four wire rope. So it won't break at the same time.
2. Is it dangerous for power failure suddenly during the elevator running?
If it occurs, the elevator will automatically stop due to the electrical and mechanical safety device. In case of power failure,elevator brakes will automatically taken. In addition, the power supply departments such as planned outage, prior notice are also operating.
3. Will us be hurt when it closed suddenly?
In the closing process, if people touch the hall door, the door of elevator will automatically restart without any danger. With anti clamping switch, once the gate touched, this switching action make the elevator unable to be closed and even reopened. In addition, closing force is also available here.
4. How the elevator running?
Elevators are operated with a counterweight wire rope through the (tractor) traction drive, making ups and downs on the guide rail.
5. Is the escalator installation complicated?
We believe the functions of an escalator are not necessarily proportional to the operation complexity. Therefore, escalators designed by us apply an integrated structure, so that the equipment is more precise and more efficient and allows easier and more convenient commissioning.
6. Do you have any cerifications?
Yes, we do with ISO9001 / CCC / CE Certificates for u.
