Escalator Drive ሰንሰለት

The escalator drive chain is divided into two parts: the main drive chain and the handrail belt drive chain. Each of these parts has different characteristics, which can affect their performance and longevity. In addition to preventing premature wear and tear, they should be designed to align the sprockets and engine chains in the correct direction. In addition, escalator drive chains should be lubricated regularly to ensure maximum performance. This can be done manually or automatically.

An escalator’s drive unit consists of an electric motor, decelerator, electromagnetic brake, and V belt. These parts transmit power to the drive wheel, which in turn drives the Trailing Rollers. A drive chain drives the Moving Handrail. This chain transfers the motive force from the gearbox shaft to the main drive shaft. To prevent excessive wear and tear, an escalator must have a safety device that disconnects the main drive motor in case of emergency.

There are a few easy ways to keep the escalator drive chain in great condition. First, be sure to check the pitch of the drive chain. Many chains are too short to be effective for heavy loads. Fortunately, there are ways to adjust the pitch of the chain without causing damage to the escalator.

Pitch of Escalator Drive Chain

The pitch of an escalator drive chain is the ratio of the number of teeth to the step pitch. There are four or six teeth in a chain. This can affect the smooth running of the escalator. Large linear movements can affect the redirecting station and disrupt the smooth running of the escalator. If this happens, the escalator may not be safe for the users. Therefore, proper design is required to minimize the risks of accidents.

The pitch of the escalator drive chain should be as small as possible to lessen the effects of chordal action. Although the installation of an escalator step chain varies by country, the principle is the same. The bearing part of the chain plate is located at the center of the step shaft. The step shaft and extended pins support the weight of the steps and travelers. If the chain pitch is too large, the escalator may not run smoothly.

Noise-reducing Device for Escalator Drive Chain

The present invention relates to the technical field of escalators and relates to a noise-reducing device for escalator drive chains. The noise-reducing device consists of a body for the drive chain and polyurethane blocks arranged in the tooth sockets. The noise-reducing device is an effective noise-reduction device for the escalator drive chain. This invention is intended to reduce noise transmitted by escalators and staircases.

The conventional structure of the escalator drive chain has many disadvantages. One of them is the high number of chain teeth. Moreover, a small chain pitch leads to more chains per step and meter and higher wear points. Another disadvantage of the conventional structure is its relatively small chain pitch. Consequently, it is essential to meet the maximum permissible chain pitch. Another disadvantage is its high cost.

Material Damage Modes of Escalator Drive Chain

Various wear modes can lead to failures of escalator drive chain and thus reduce its wear resistance. These problems may be avoided by paying attention to continuous safety research. In a study, various material damage modes such as micro cracking, wear damage, and decarburization defect were analyzed. In order to understand how these modes affect the chain's performance, tensile tests and friction&wear experiments were conducted.

The preventive maintenance chart must include safety rules, testing and adjustment procedures, and pictorials for all mechanical components. The maintenance chart should include instructions for removing floor plates, removing interior panels, and replacing comb segments. The chart should also provide a detailed lubrication schedule with a description of where to lubricate each component. It should also include electrical and control wiring diagrams.

For a general guide to choosing a chain, check your manual for a chain size chart. There are commonly listed chain sizes as well as እንጆሪ, which are standardized by ANSI. The first digit of a chain's pitch measures the distance between the rivets. For example, a "5" chain has a pitch of five eighths of an inch. A sprocket with a "20" code is a sprocket with two strands running parallel to each other.

The last two parts of a chain or sprocket are known as the idler sprocket. These parts are secured to the shaft by a keyway or a set screw, according to ANSI standards. However, these guidelines are only applicable to some applications, so be sure to contact the sprocket supplier to find out the proper keyway size. A chain should be lubricated before it is used. The escalator chain oil should penetrate small clearances in order to be effective.
