The raceway formed from the gasket and the shaft washer is provided with radial rollers (6); and the gasket is uniformly provided with screw holes circumferentially in the position corresponding to the shaft washer and the seat ring. The utility model is characterized in that the external diameter of the shaft washer is provided with a step (9); and the radial rollers are uniformly distributed on the radial retainer (7) in the position of the step of the shaft washer. The radial retainer separates and retains the radial roller away so that the slewing bearing has favorable flexibility and low noise when working; and the step arranged at the radial raceway of the external diameter of the shaft washer guarantees the installation and fixation of the radial retainer. The utility model increases the limiting speed of the slewing bearing and effectively prolongs the service life of the slewing bearing.
Description
Technical field
The utility model belongs to the turntable bearing technical field, refers more particularly to a kind of rotating disk high speed combination bearing.
Background technique
Existing YRT series turntable bearing is mainly used in the accurate digital control milling machine, also can be used in the configuration of chuck, surveying instrument, testing installation and rotary table; As shown in Figure 1, its structure constitutes seat ring (5), blowout patche (1), packing ring (4), packing ring (4) is arranged between blowout patche (1), seat ring (5), respectively is provided with a cover axial retainer (3) and axial roller (a 2) assembly in the upper and lower raceway that packing ring (4) and blowout patche (1), seat ring (5) form; Be provided with radial roller (6) in the raceway that packing ring (4) and blowout patche (1) form; This YRT series turntable bearing axially, radially strong, the inclination rigidity height of bearing capacity and running accuracy are high, but be not suitable for the high speed rotating occasion.
Summary of the invention
In order to overcome the deficiency in the background technique, the utility model discloses a kind of rotating disk high speed combination bearing, by the radial roller that radially retainer isolation keeps existing YRT series turntable bearing is set, the flexibility when making the turntable bearing running is better, noise is low with the high speed combination bearing for described rotating disk; And radially set up step in the raceway place at the blowout patche external diameter, guaranteed the radially installation and the location of retainer; The utility model has improved the limit speed of turntable bearing, and has effectively prolonged the working life of turntable bearing.
For achieving the above object, the utility model adopts following technological scheme:
A kind of rotating disk high speed combination bearing comprises blowout patche, seat ring, packing ring, and packing ring is arranged between blowout patche, seat ring, respectively is provided with an axial retainer of cover and an axial roller assembly in the upper and lower raceway that packing ring and blowout patche, seat ring form; Be provided with radial roller in the raceway that packing ring and blowout patche form; Blowout patche, seat ring corresponding position, packing ring is along circumferentially being laid with screw hole; Blowout patche external diameter radially raceway place is provided with step, and radial roller is distributed on radially on the retainer and places blowout patche step place.
Described rotating disk high speed combination bearing, radially retainer is set to circle structure, and a week is laid with the pocket hole on the annulus short transverse.
Described rotating disk high speed combination bearing, radially the pocket hole shape is set to cylindricality, circle on the retainer.
Described rotating disk high speed combination bearing, radially retainer adopts nylon material.
Because adopt aforesaid technological scheme, the utility model produces following good effect:
1, because radial roller is isolated by nylon cages radially keeps, runs foul of each other and rub between radial roller when preventing turntable bearing work, and nylon cages is in light weight, make that the flexibility of turntable bearing is better, quiet effective, noise is low; Promptly improve the limit speed of turntable bearing, reduced the heating of turntable bearing using process again, and effectively prolonged the working life of turntable bearing.
2, owing to radially set up step in the raceway place, guaranteed the radially installation and the location of retainer, made the structure of blowout patche compact more at rotating disk blowout patche external diameter.

Fig. 3 is the utility model retainer schematic representation;
Fig. 4 is the utility model blowout patche schematic representation;
Among the figure: the 1-blowout patche; The axial roller of 2-; The 3-axial cage; The 4-packing ring; The 5-seat ring; The 6-radial roller; 7-is retainer radially; 8-pocket hole; The 9-step.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified;
As Fig. 2,3 or 4 described rotating disk high speed combination bearings, comprise blowout patche 1, seat ring 5, packing ring 4, packing ring 4 is arranged on 5 of blowout patche 1, seat rings, respectively is provided with an axial retainer 3 of cover and axial roller 2 assemblies in the upper and lower raceway that packing ring 4 and blowout patche 1, seat ring 5 form; Be provided with radial roller 6 in the raceway that packing ring 4 and blowout patche 1 form; Blowout patche 1, seat ring 5 corresponding positions, packing ring 4 is along circumferentially being laid with screw hole; Blowout patche 1 external diameter radially raceway place is provided with step 9, and radial roller 6 is distributed on radially on the retainer 7 and places blowout patche step 9 places; Radially retainer 7 is set to circle structure, and a week is laid with pocket hole 8 on the annulus short transverse; Radially pocket hole 8 is set to cylindricality, circle on the retainer, decides according to the roller shape of radially retainer 7 isolation maintenances; Radially retainer 7 adopts nylon material.
Rotating disk described in the utility model high speed combination bearing during the bearing assembling, is at first chosen the blowout patche 1 by processes, joins radial internal clearance according to radial roller 6 sizes and packing ring 4 outer raceway sizes, joins axial internal clearance according to packing ring 4 height dimensions again; Radially, axial internal clearance qualified after, carry out bearing assembling; At first with blowout patche 1 small end face upwards, put into axial cage 3, by technological requirement at axial cage 3 pocket hole built-in shafts to roller 2; Put into radially retainer 7 at blowout patche 1 raceway then, the radial roller 6 of radially packing in the retainer pocket hole 8; Packing ring 4 is installed, and because of the turntable bearing radial internal clearance is negative play, promptly ring is interference fit with radial roller 6 in the packing ring 4, need evenly firmly packing ring 4 to be pressed into, and be standard with packing ring 4 one end face engagement shafts to roller 2; Put into another part axial cage 3 in packing ring 4 other ends, to roller 2, assemble seat ring 5 at last at axial cage 3 pocket hole built-in shafts, and with blowout patche 1, seat ring 5 corresponding aperture place bolt.
In order to guarantee the radially installation of retainer 7, the structure of 1 of blowout patche has been carried out new design, by radially setting up step 9 in the raceway place, make the structure of blowout patche 1 compact more at blowout patche 1 external diameter, guaranteed the radially installation and the location of retainer 7; Because adopting radially, retainer 7 isolation keep radial roller 6, reduced the quantity of radial roller 6, though the radial load of turntable bearing reduces to some extent, but the limit speed of turntable bearing is largely increased, and has satisfied the application in the client field that precision prescribed is high in high precision numerical control turntable, weaponry, Aeronautics and Astronautics, measurement and test.
