Slew bearing catalogue

The catalog of FH slewing bearings contains thousands of standard models, and we also focus on the research and development of non-standard slewing bearings. What is a slewing bearing? Slewing bearings can be divided into many different types according to their different structural forms

5 Steps to Testing an Excavator Slewing Bearing

The slewing ring is an important part of the excavator. There are internal teeth and external teeth, and the size is different. It mainly depends on the tonnage. The 8T generally uses a slewing ring of about 760mm. The external teeth are mainly used for truck cranes, tower cranes, excavators, Pile drivers, construction vehicles, radar scanning equipment. How to detect the excavator slewing bearing?

How to choose a suitable slewing ring gear?

When designing pinion teeth, one of the important parameters is the modulus. The meshing of the gears produces the pulsation of the meshing, which is caused by the elastic deformation of the deformation of the gear teeth. As one of the basic parameters for designing gears, the modulus of the gear (if large) (that is, the size of the gear is large) has a relatively large load capacity.

How to calculate the friction force of slewing bearing?

In fact, slewing bearings, like many other mechanical equipment, need to be calculated and designed when they are used. Because it is mainly bearing capacity, the calculation of its friction moment and so on needs to be very rigorous. Friction torque: the product of the friction force and the friction arm. The friction arm is the nominal radius of the bearing. Before determining the magnitude of the friction force, determine whether it is static friction or sliding friction, because the calculation methods of the two friction forces are different.

Slewing ring bearing with internal gear

Slewing bearing with internal teeth: Since the teeth of the internal gear slewing bearing are inside the slewing bearing, the overall appearance is relatively neat. The meshing position of the driving gear and the slewing ring is inside the slewing ring, so there is no need to install a safety shield.

slewing ring with motor

The biggest difference between a slewing ring hydraulic motor and an electric motor is that the source of power is different. The slewing ring hydraulic motor is pressure potential energy, while the electric motor is electric potential energy.

slewing bearing dimensions

The dimensions of the slewing bearing is generally much larger than that of the bearing. It can be divided into external gear type, internal gear type, and gearless type. Its main feature is "high load and low speed". The slewing bearing dimensions can be larger.
