Relying on the support provided by the shaft and bearing seat, this movement will increase the internal stress of the bearing. The deformation of the shaft and bearing seat under the influence of load will be transferred to the bearing, causing higher stress, which may lead to premature failure of the bearing or unstable torque. Bearings are excellent in ultra-thin cross section, and can provide large-size lightweight products that can bear light to medium loads under the conditions of slow operation or intermittent operation. In fact, this kind of bearing is often used in light load environment, with the main goal of reducing weight and saving space. The load value is obtained on the premise that both the shaft and the bearing seat are light. In this way, compared with the traditional series bearings with heavy cross-section, it can be loaded on the rings in a wider range. Therefore, the bearing limit is not based on ABMA.
The influence caused by deformation of different shafts and bearing seats is confirmed by tests. If problems occur repeatedly, it may be necessary to increase the stiffness of the shaft and bearing seat. If the shaft and bearing seat have sufficient rigidity, the bearing may bear higher loads than those listed in the sample. The radial static load is calculated based on the allowable contact stress. It is assumed that the raceway can provide proper support, so that the balls can be evenly loaded. Radial dynamic load has been included in life calculation. It is assumed that both the shaft and the bearing seat have sufficient rigidity to support the load without causing serious deformation of the bearing ring. When the bearing has high enough rigidity, it can also have higher limit load parameters, so that the movement of bearing raceway under load will be better regulated. The chamfer size is the fillet diameter of the shaft or bearing seat, so that there will be no interference at the edge of the bearing. Contact the delivery date and the minimum quantity.
Reduce weight, reduce product design envelope size and increase design
Flexibility-without reducing bearing performance and service life-some customers have told us that they need such a new compact slewing bearing shaft
Cheng. Customized configuration to meet the special needs of customers-a variety of transmission options, gears/timing belts, mounting hole styles, and special design for harsh working environment-AISI 440 C steel
Raceway, steel reinforced seal. We listened to the customer's requirements and responded, and designed a small-sized thin-section slewing bearing for robots, radar antennas, factory positioning stations, inspection stations and other places to meet the customer's needs. This kind of bearing is called. series. The advantages of the new series over the traditional slewing bearing include:
It is of great significance to reduce the size-that is, to increase the design flexibility and reduce the weight. Higher precision-the expanded radial bearing section increases stiffness, and optional preload and clearance can cope with working conditions with different torque or deflection limits. Seal made of ring gear reinforced steel ring Easy to use-quick installation and replacement.
