Traction machine reducer

The reducer is an essential component in a geared traction machine, typically installed between the traction motor shaft and the traction sheave shaft. It plays a key role in transferring power efficiently while adjusting the speed and torque according to the system's requirements.

There are various types of reducers, each with unique characteristics. One common type is the worm reducer, which consists of a worm gear (with a drive shaft) and a worm wheel mounted on the housing bearing with a driven shaft. This type of reducer offers a wide range of speed ratios, usually from 18 to 120, and the worm gear typically has at least 30 teeth. While its efficiency is lower compared to gear reducers, it provides a compact and space-saving design, making it ideal for applications where size is a constraint.

The worm reducer has several notable features. It provides a large transmission ratio, operates with low noise, and ensures stable performance. Additionally, when the worm gear is driven by the worm wheel, the reverse efficiency is relatively low, which gives the system a certain level of self-locking capability. This characteristic is particularly beneficial in elevator systems, as it enhances the braking torque and improves safety when the elevator is stationary.

In summary, the worm reducer is a reliable and efficient solution for many mechanical systems, especially in elevator applications where compactness, stability, and safety are crucial factors. Its unique design and operational benefits make it a popular choice in modern traction machines.

Synthetic Sleeper

Role of sleeper:

1. Bear the load, transverse force and longitudinal horizontal force transmitted from the rail, and distribute them evenly on the track bed;

2. Connect the two rails together to fix the rail position and keep a certain distance (gauge);

3. Fix the direction of the railway so that the railway will not have longitudinal and transverse displacement due to the force
