Bearings are important parts of cranes, and their use and maintenance are also of concern to everyone. Single-girder cranes usually refer to single-girder bridge cranes. The main beams of single-beam crane bridges mostly use I-shaped steel or a combined section of steel and steel plates. The hoisting trolley is often assembled by chain hoists, electric hoists, or hoists as parts of the lifting mechanism. Then, crane bearings often overheat during use. Then, how should we solve the overheating condition of cranes? Let the company explain in detail for everyone!
First, let's briefly understand the causes of overheating of crane bearings.
Crane bearing (bearing) needs constant rotation and friction under working condition. During the friction process, heat (Heat) will be continuously generated. This is also the most basic physics knowledge in middle school. Therefore, the overheating of the lifting bearing is mostly caused by the heat accumulation caused by its rapid rotation.
However, the continuous rotation and friction of crane equipment during use is inevitable, and we can only find ways to improve the problem of crane bearing overheating. The single beam crane has two operation modes: ground and air. There are two types of ground operation: wired handle operation and remote control handle operation; aerial operation refers to operation in the driver's cab. The driver’s cab has two types: open and closed. It can be divided into two types for installation on the left or right according to the actual situation. There are two types of entry directions: side and end to meet the needs of users. So, how to solve the problem of crane bearing overheating?
The company’s professional technicians told us that if we want to improve the overheating of crane bearings, the most common way is to conduct heat dissipation design or cooling treatment on crane bearings, so as to improve the overheating of crane bearings. ) When the temperature is raised, the heat dissipation or cooling can be performed synchronously, and then the purpose of avoiding the easy overheating of the lifting bearing (bearing) can be achieved.
In view of the exquisiteness and compactness of the crane bearing components, the cooling method is easier to achieve than the heat dissipation design method. The cooling water is introduced into the bearing shell or directly supplemented by the cooling water circulation (continue). The result of cooling down the temperature of the lifting bearing can be achieved. Single-girder cranes usually refer to single-girder bridge cranes. The main beams of single-beam crane bridges mostly use I-shaped steel or a combined section of steel and steel plates. The hoisting trolley is often assembled by chain hoists, electric hoists, or hoists as parts of the lifting mechanism.
