What is the elevator traction sheave?

Elevator traction sheave is the rope pulley device which is responsible for transmitting traction power. It is the important parts of the elevator.

How does the elevator traction sheave work?

The elevator traction sheave moves the car by friction with the wire rope. In short, the traction system operation depends on the rotation from traction sheave and the up and down movement of the wire rope.

Common Problems and Solutions for Elevator Traction Sheave

Elevator traction sheaves are an important part of the elevator system, and frequent problems including:

• Rim wear
• Bearing damage
• Gear wear

These problems can lead to unstable operation, increased noise and energy consumption or other problems.

Solutions:

1.Regular maintenance and inspection, and timely replacement of worn or damaged parts are necessary in daily using
2.Using high-quality traction sheaves, bearings and gears to extend their service life
3.Using suitable lubricants to reduce friction and energy consumption
4.Improving the design of traction sheaves to enhance their durability and stability
Through the above measures, the common problems of traction sheave can be solved effectively.

How to order a elevator traction sheave quickly?
1.Check the elevator traction machine nameplate to confirm its model number
2.Confirm the rope diameter & number of grooves (Let’s take the example of ordering an elevator MX32/MX40 traction sheave）
Find the sign of “Marking of rope grooves”
n x D13 51140171V000 S33 80°
80°=Angle of groove
S33=Rope pitch
D13=Rope diameter
n=Number of ropes
If you cannot find the above markings, you need to measure them on site.
3.Traction sheave groove pitch and groove bottom width
The MX32 sheave groove angle ranges from 60° to 105°, so the groove bottom width is required to determine the groove angle.
