3 Reasons-Why crossed roller bearing is the most suitable for robot arm?

The stretching and lateral movement of the robot arm all belong to linear motion. There are many kinds of mechanism to realize the reciprocating and linear motion of arm, such as piston oil (gas) cylinder, gear rack mechanism, screw nut mechanism and connecting rod mechanism. Because the piston oil (gas) cylinder is small in size and light in weight, it is widely used in the robot arm structure.

There are many kinds of mechanisms to realize the rotary motion of robot arm, such as vane rotary cylinder, gear drive mechanism, sprocket drive mechanism, piston cylinder and connecting rod mechanism. The most suitable bearing for robot arm is cross roller bearing. Why do you say that?

What kind of bearing cannot be reused and must be replaced?

How to select the Marine crane slewing bearing?

Deck machinery is the special machinery equipment for ship outfitting, mainly including the anchor winch and ship crane installed on deck. Among them, the ship crane is mainly equipped with a series of characteristics, such as compact structure, convenient operation, large lifting weight, quick action, high efficiency and convenient maintenance, etc., in a large bulk cargo ship of 30,000-50,000-ton class, and plays an important role in modern ship deck machinery.

At present, the Marine crane has formed a series of production in China through the introduction and transformation of foreign technology in the past 20 years. Except the ordinary crane, the slimming crane, the double crane and the hose crane have also been produced in series. However, most ship cranes were imported from abroad before 2003, especially the slewing bearing in the rotary mechanism which connected the rotating tower body and fixed base column. As an extremely large ship crane kit, due to the particularity of the use environment, the selection and development design of the ship crane were still blank in China at that time.

Common faults and troubleshooting of mobile cranes slewing bearings

Mechanical failure
Crane slewing bearing plays the role of connecting the truck and chassis  parts in the rotary mechanism, and also supports the whole rotating part of  crane.If the steel ball in the swing bearings is damaged and the raceway  abrasion will affect the work of the rotary mechanism, in severe cases, the  rotary mechanism will be heavy and make noises, and the pressure of the  rotary hydraulic system will exceed the rated value.When hoisting and  unloading are carried out at the stop of rotation, the vibration amount of  the slewing bearings will be too large at the moment of falling and falling  together, indicating that the clearance amount of the slewing ring has  seriously exceeded the limit.At this point, the turntable bearings should  be repaired or replaced.

The general causes of mechanical failure are inadequate maintenance and  improper use.
