Rolling bearing which may be used as slewing ring - has grooved inner race with internal teeth and segmented outer race

Abstract: The rolling bearing race assembly has internal gear teeth in its inner race. The inner race has external groove for thrust and radial load bearing rollers. The external race inner rim projects into the groove. The race (1) with groove (2) is an integral ring. The race with inner rim (4) is formed by joining several segments connected to another integral ring (8). The inner integral race (1) has internal gear teeth (12).

Large-scale forging and manufacture process wind electricity slewing bearing forging and manufacturing process

Abstract: The invention relates to a large-scale forging and manufacture process wind electricity slewing bearing forging and a manufacture process, the manufacture process comprises the following steps: selecting materials, blanking, heating, forging, performing thermal treatment after forging, front machining, rear machining, performing physical and chemical inspection, ultrasonic flaw detection, performing finish machining, cleaning and packaging. The first normalising temperature is higher than second normalising temperature, the second normalising can not destroy the first normalising effect, the structure refinement effect is more obvious; normalising adopts heating by segments, the second segment heating reduce the difference of temperature between surface and core on the basis of first segment heating, the thickness direction structure of the large-scale forging and manufacture process wind electricity slewing bearing forging is fine and uniform, the heat treatment employs heating by segments, and the normalising and tempering technical effect can be further guaranteed, and the requirements that elongation percentage is greater than or equal to 13 and the transverse plane shrinkage is greater and equal to 55 can be guaranteed.

Slewing bearing ferrule circular degree error automatic detection and correction device

Abstract: The invention provides a slewing bearing ferrule circular degree error automatic detection and correction device, and belongs to the technical field of industrial detection and correction. The slewing bearing ferrule circular degree error automatic detection and correction device comprises a lathe bed, ferrule supporting and slewing driving devices, circular degree error detection devices, circular degree error correction devices, lifting and warping-resisting devices and a data collecting operation and display system. The ferrule supporting and slewing driving devices support a slewing bearing ferrule to rotate for one circle, the data collecting operation and display system collects the data output by the circular degree detection devices, the circular degree error values, the correction positions and the correction strokes can be obtained, and the circular degree error correction devices automatically carry out pressure correction according to the calculated results. According to the slewing bearing ferrule circular degree error automatic detection and correction device, the lifting and warping-resisting devices are adopted so that interferences between detection and correction and planar warping of the ferrule can be avoided, three eddy-current sensors are adopted in the circular degree error detection devices, the discretion fast Fourier transform is carried out on the collected signals so that the interferences of the eccentric errors of the slewing bearing ferrule can be eliminated, and the detection accuracy is improved.
