The piston rod is the connecting component between the piston and the connecting rod

The piston rod is the connecting component between the piston and the connecting rod, used to convert the reciprocating linear motion of the piston into the rotational motion of the connecting rod. It is usually made of high-strength alloy steel or cast iron.

Spur gears have the following characteristics

Spur gears are a common mechanical transmission device composed of multiple equally spaced gears. Each gear has a certain number of teeth that can bite and rotate together.

Detailed information on daily maintenance of pulleys

The manufacturer of the lifting pulley tells you about the daily maintenance of the pulley. At present, pulleys are commonly used tools in our daily lives, and they are a very labor-saving device that has applications in most fields. Among them, hot rolled pulley is widely used and has its own high strength. People like functions are very popular, but they are usually maintained after the device is in use to extend its lifespan. So, what is the daily maintenance of pulleys? Let's take a look at the analysis below.

Introduction to the characteristics and advantages of hot-rolled pulleys

The appearance of the hot rolled pulley groove is moistened and wear-resistant, and can be heat treated, with good strength and durability.

Daily maintenance and upkeep of hot-rolled pulleys

Hot rolled pulleys are primarily manufactured using the hot rolling process. This equipment is a replacement product of cast pulleys and double spoke plate pulleys. Hot rolled pulleys are not only light in weight and good in quality, but also have high hardness and wear resistance. They also look more concise and beautiful, about 40% lighter than cast slide pulleys of the same specification.

There are several requirements to pay attention to during the daily maintenance of hot-rolled pulleys:

Main functions and material matters of crane pulleys

In cranes, the main function of pulleys is to thread and wind steel wire ropes. Pulleys are divided into movable and fixed pulleys based on whether the central axis is moving or not; According to the manufacturing method, it is divided into cast iron pulleys, cast steel pulleys, welded pulleys, nylon pulleys, and aluminum alloy pulleys. Cast iron pulleys, including gray cast iron (HT1533) pulleys and ball plug cast iron (QT4010) pulleys. Grey cast iron pulleys have good technological performance, have little wear on steel wire ropes, but are fragile, and are mostly used in light and intermediate operation levels; Ductile iron pulleys have higher strength and impact toughness than gray iron, so they can be used in heavy-duty operations.
