Abstract
The utility model discloses a stable slewing bearing. The stable slewing bearing comprises an upper seat ring and a lower seat ring, wherein the upper seat ring is arranged above the lower seal ring, a connecting disc is arranged on the supper surface of the upper seat ring, bolt holes are formed in the peripheral wall of the connecting disc, an upper guide ball ring groove is formed on the lower surface of the upper seat ring, a lower ring groove which is matched with the upper guide ball ring groove is formed on the upper surface of the lower seat ring, guide balls are rotatably arranged in the upper and lower ring grooves, an oil duct is formed on the side wall of the lower seat ring and communicated with the lower ring groove, and an oil cup is arranged on an oil duct opening. By utilizing the slewing bearing, the weight and volume of the seat rings are reduced, and the slewing bearing is convenient to install and use.
Description
Technical field
The utility model relates to supporting member, specifically a kind of stable pivoting support.
Background technique
Stable pivoting support is a kind of large size bearing that can bear combined load, can bear simultaneously larger axially, radial load and tilting moment, stable pivoting support is again turntable bearing, some people also is called: the rotary support supporting of holding, circle round, stablizing pivoting support uses very extensive in real industry, be called by people: " joint of machine ", be to do relative rotation motion between the two articles, need bear simultaneously again the mechanical necessary important transmission part of axial force, radial force, tilting moment.Along with developing rapidly of machinery industry, stablize pivoting support and be widely used in industries such as ship equipment, engineering machinery, light industry and machinery, metallurgical machinery, medical machinery, industrial machineries.
There is complex structure in the stable pivoting support of prior art, installs and uses the defectives such as inconvenient.
The model utility content
The utility model provides a kind of seat ring weight that alleviated, and has reduced volume, is convenient to install and use, and saves the stable pivoting support that the man power and material increases the bearing capacity of stablizing pivoting support.
The utility model technical solution problem provides following scheme:
A kind of stable pivoting support, comprise upper and lower two seat rings, it is characterized in that: described top race places the top of bottom race, the upper surface of described top race is provided with land, wall is provided with bolt hole around the described land, the lower surface of described top race is provided with leads annular groove on the pearl, the upper surface of described bottom race is provided with and leads the lower annular groove that half circle groove is complementary on the pearl, be rotatablely equipped with in the described upper and lower annular groove and lead pearl, the sidewall of described bottom race is provided with oil duct, described oil duct is communicated with lower annular groove, and described oil duct junction is provided with lubricating cup.
Described bottom race is provided with mounting hole.
The utility model compared with prior art, volume has reduced, and the bundling type structure with original changes split-type structural into, upper and lower seat ring is formed upper and lower formula install, and land is set above top race, a plurality of bolts hole are set on the land, are connected firmly, increase many so that stablize the carrying capacity of pivoting support, so that installation is simpler, the manpower and materials that expended when having saved loading and unloading.
Description of drawings
Fig. 1 is structural representation of the present utility model.
