Slewing bearing, also known as turntable bearing, is a kind of supporting rotating part widely used in various mechanical equipment. Due to transmission requirements, slewing bearings usually have teeth, and the most common ones are spur gears and helical gears. The most intuitive difference between spur gears and helical gears is the different gear shapes. In addition, there are differences in load, noise, etc. Let's take a look at it together.

In modern mechanical equipment, slewing bearings are key components, and their selection is crucial. This article will discuss how to choose a suitable slewing bearing from many aspects.

As an important piece of equipment in construction machinery, the performance of the slewing bearing of the excavator directly affects the operating efficiency and stability of the excavator. During actual use, the excavator slewing bearing sometimes emits Abnormal noise not only affects the work effect, but may also cause damage to the equipment. Below, we will analyze the causes of abnormal noise in the excavator slewing bearing from several aspects.

Large long shafts, roller shafts and gear shafts are common shaft parts in mechanical engineering. They each have unique functional characteristics, process technology and application fields
