What is the importance of the turntable bearing?

The turntable bearing is a new type of mechanical parts, which consists of inner and outer rings, rolling elements, etc. The turntable bearing is a large bearing that can bear comprehensive loads, and can bear large axial and radial loads and overturning moments at the same time. Let see and know more about the turntable bearing.

What are the advancements in the production of turntable bearings?

(1) Through finite element analysis, appropriately increase the thickness of the plate at the connection between the turntable and the turntable bearing, so as to improve the structural rigidity of the turntable.

(2) When designing large-diameter turntable bearings, the safety factor should be appropriately increased; appropriately increasing the number of rollers can also improve the contact between the rollers and the raceway.

(3) Improve the manufacturing accuracy of the turntable bearing, focusing on the heat treatment process. The intermediate frequency quenching speed can be reduced, and a larger surface hardness and hardening depth can be obtained to prevent quenching cracks on the surface of the raceway.

Do you know what structure turntable bearing has?

1. Single row cross roller turntable bearing

The single-row cross-roller turntable bearing consists of two races, with compact structure, light weight, high manufacturing precision, small assembly clearance, and high requirements for installation accuracy. Force, tipping moment and larger radial force are widely used in lifting and transportation, construction machinery and military products

2. Three-row roller turntable bearing

The three-row roller turntable bearing has three races, and the upper and lower and radial raceways are separated, so that the load of each row of rollers can be accurately determined. It can bear various loads at the same time, and is the one with the largest bearing capacity among the four products. The shaft and radial dimensions are large and the structure is firm. It is especially suitable for heavy machinery requiring large diameters, such as bucket wheel excavators, wheel Cranes, marine cranes, port cranes, molten steel running table and large tonnage truck cranes and other machinery.

What is the working principle of turntable bearing?

The working principle of the turntable bearing is simple, and the way of moving objects is changed from sliding to rolling, reducing frictional resistance. The following is a detailed introduction to its working principle:

The turntable bearing mainly relies on lubrication and friction to achieve the effect of operation.

Internally, turntable bearing relies on the mutual friction between the ball and the steel ring for the purpose of operation.

Externally, turntable bearing relies on the friction between the turntable bearing and other components to start the operation, rub against each other, and drive the object to operate.

The turntable bearing have been used in many fields LYXQL Slewing Bearing Co., Ltd.Maintains close relationships with customers in turntable bearing industry, and is committed to strengthening production and operation, improving quality and safety.
