Product Description

Production descrption:

Double Row Ball Slewing Bearing—-Internal Gear

Double Row Ball Slewing Bearing—-Internal Gear

Characteristic of structure, performance and application

Double row ball slewing bearing has 3 seat ring, the steel ball and the spacing block can be directly arrange into the upper and lower races, 2 rows of upper and lower steel balls with different diameter are fitted according to the stress condition.

This kind of open assembly is very convenient, for the upper and lower bear raceway arc angles is 90°,which can bear large axial forces and tilting moment. When the radial force is greater than 0.1 times the axial force need to be specially designed the raceway.

Double row different ball slewing bearing’s axial and radial size are relatively large and CHINAMFG in structure, so it is specially suitable for the medium diameter tower cranes, truck mounted cranes etc. loading and unloading machinery.

Can internal gears be used in both horizontal and vertical orientations?

Yes, internal gears can be used in both horizontal and vertical orientations. Here’s a detailed explanation of the versatility of internal gears in different orientations:

Internal gears are a type of gear where the teeth are located on the inner surface of the gear. They are designed to mesh with external gears, which have their teeth on the outer surface. The meshing of internal and external gears allows for torque transmission and motion transfer.

Internal gears are not limited by orientation and can be used in various orientations, including both horizontal and vertical arrangements. The design and functionality of internal gears allow them to adapt to different orientations without compromising their performance or reliability.

Horizontal Orientation: In a horizontal orientation, where the rotational axis of the gears is parallel to the ground, internal gears can efficiently transmit torque and motion. The meshing between internal and external gears remains consistent, and the load-carrying capacity of the gears is not significantly affected by the orientation.

Vertical Orientation: In a vertical orientation, where the rotational axis of the gears is perpendicular to the ground, internal gears can also be effectively utilized. The gravitational force acting on the gears in the vertical orientation does not hinder their ability to transmit torque. However, it is important to consider factors such as proper lubrication, bearing selection, and load distribution to ensure optimal performance and minimize any potential issues associated with the vertical arrangement.

When using internal gears in vertical orientations, it is essential to consider the effects of gravity on the gear system. Gravity can introduce additional forces and moments that need to be accounted for in the gear design and analysis. Factors such as lubrication and bearing selection become critical to handle the resultant forces and minimize wear or excessive loads on the gear teeth.

Overall, internal gears are versatile and can be successfully employed in both horizontal and vertical orientations. Proper design considerations, including load distribution, lubrication, and bearing selection, ensure the efficient and reliable operation of internal gears regardless of their orientation.
