How does slewing support adapt to temperature and working environment
Slewing supports are called "joints of the machine" in the machinery industry. It is the relative rotational motion between two bodies and can withstand axial force, radial force and tilt moment.
Heat treatment of slewing bearing track and gear:
Rotary bearing raceway after surface induction quenching treatment, quenching hardness is guaranteed at HRC55-62, can reach enough hardening layer depth.
One of the slewing bearing rings is usually toothed because of the need to transmit the force. The heat treatment state of gears is usually normalizing or quenching and tempering. The tooth surface can also be quenched according to the user's requirements. The quenching hardness is HRC50 ~ 60, which can ensure sufficient depth. According to the different applications, gear quenching can be divided into full tooth quenching and single tooth induction quenching. Single tooth induction hardening can be divided into root hardening and tooth surface hardening.
Rotary bearing to adapt to temperature and working environment:
The slewing bearing can operate normally in the temperature range from -300C to +700C. If the user needs to adapt to lower or higher temperature slewing bearing, our company can carry out special design. If the slewing support is used in a particularly harsh environment, such as Marine climate, dust or abrasive particles, sand, cement, pulverized coal, etc. Special seals, protective devices and suitable oil channels must be selected. So in order for your support to function properly, I want to do routine maintenance and maintenance work.
