Features and applications of slewing bearings
Slewing bearings are an important part of many automobiles and machine tools. There are many types of turntable bearings. They do not need a support body during work. As long as the gap between the supporting surface and the working surface is kept at a certain height, the turntable can be kept in balance. It can be selected according to the needs, and the scope of use is also very wide. It is generally suitable for precision transmission parts in machinery. In which aspects are the specific slewing bearings used? Heng Guan Bearing will give you a detailed explanation on the characteristics and applications of slewing bearings.
1. Characteristics of slewing bearings
Slewing bearings are generally suitable for bearing radial loads (slewing torque) greater than 10N.m, and axial loads not exceeding 20N.m. The steel used for the balls and raceways of the slewing bearing is carburized on the surface and has a high surface hardness, which is suitable for occasions with impact loads.
The raceway is generally produced by precision machining, and its diameter can be selected according to needs; while the inner and outer rings are detachable for easy maintenance and replacement. There are many types of slewing bearings, which can be selected according to needs. The turntable bearing is an integral assembly composed of high-precision, high-performance steel balls and graphite, and is mainly used in precision rotating instruments.
2. Application of slewing bearings
The slewing bearing is a ball bearing with high precision, large load capacity and high stability, which is widely used in aerospace industry, petrochemical production and machinery manufacturing industry and other fields. The balls of the slewing bearing are precisely machined, so there is no special requirement for the material, and different grades of materials can be selected according to the application field. Slewing bearings have a wide range of applications and are generally suitable for precision transmission parts in machinery.
The characteristics of the turntable bearing are determined by the structure of the bearing. There is only one set of support in the whole structure, and no support body is needed in the work. As long as the gap between the support surface and the working surface is kept at a certain height, the turntable can be maintained balance.
