  • SLEWING RING SELECTION - Chain and Drives

    SLEWING RING SELECTION SLEWING RING FUNCTIONS BEARING FUNCTION The knowledge of loads and working conditions is necessary to allow us to design and dimension the 'BEARING' function of the slewing ring i.e : movement type, speed, accelerations, temperatures, environment, etc. The transmission of loads from one raceway to another varies according to

    In addition, a slewing bearing typically includes features for simple and quick attachment to those adjacent structures, and a feature to facilitate the mechanical rotation of one ring and its adjoining structure relative to the other. Slewing ring bearings have traditionally been thought of as large-diameter, heavy section, low-precision bearings.

    The type of the slewing bearing type was 132.45.2800.03. The slewing bearing began to serve from Jul. 2013 and its vibration data were collected from Feb. 2015 to Dec. 2017 about every 2 months. No artificial defect was manufactured on the slewing bearing for fault simulation. The complicated practical working condition and equipment led to combined faults occurring on the slewing bearing.

  • Combined Failure Diagnosis of Slewing Bearings

    Through defined inductive heating and quenching with the coolant, the microstructure of the steel is specifically changed - the material hardens. This physical effect is used both for gear teeth and raceways. The induction solutions from SMS Elotherm provide the exact energy required for the ring hardening process.

    Due to its versatility, a slewing bearing is considered the go-to solution across different slewing products. For installation, the most basic layout is using a slewing ring and pinion. Different gear orders and reduction rations can be achieved by changing the number of teeth and gear module between the pinion and the slewing ring.
