Description
Technical field
The invention belongs to the bearing technical field, relate in particular to a kind of large turn angle ball support.
Background technology
At present, adopt neoprene bearings to connect and transmit vertical load and horizontal force and reach because of superstructure and be out of shape needed horizontal force and corner requirement between rack building top and the pillar more, because the allowable compressive stress that neoprene bearing has is little, fairness limit is little, therefore its bearing capacity is little, corner is little, the horizontal force distortion is little, only be applicable to the rack of little span (span is less than 30 meters), space truss structure building for large span, neoprene bearing incompatibility requirement, people adopt that the rigidity that improves rack reduces that neoprene bearing bears because of superstructure because corner and horizontal force that deadweight and variations in temperature cause, make the construction costs increase.People adopted steel support afterwards, because upper base plate adopts " worker " font structure, the upper edge downside of base and upper base plate plane contact, when producing corner and uplift force, the upper edge downside and the upper base plate of base become line and contact, and downforce is even, still, uplift force is inhomogeneous, has reduced application life; And the slewing area of upper base plate is subjected to the gap restriction by its side and base, and therefore, corner little (being generally less than 0.02 radian) does not fit into big corner requirement.
Summary of the invention
The technical problem that the present invention solves just provides that a kind of corner is big, bearing capacity is big, pull out force is even, construction costs is low, a kind of large turn angle ball support of long service life.
The technical scheme that a kind of large turn angle ball support of the present invention adopts is: comprise casing and the base in casing, in described base, be provided with upper base plate, described base inner wall is the sphere that top has the upper base plate mouth, this base is made up of upper bed-plate and lower bottom base, described upper base plate comprises shoulder on the upper base plate, shoulder under upper base plate waist and the upper base plate, shoulder is protruding for the ball that is complementary with the base inner wall sphere under the described upper base plate, the radius of upper base plate mouth is less than the protruding radius of described ball, be provided with between described upper base plate mouth edge and the described upper base plate waist at interval, be provided with annular oil storage tank at described base inner wall, be provided with ring-like seal cover board at described base upper surface, the contact surface of described upper bed-plate and lower bottom base is stepped.
A kind of large turn angle ball support provided by the present invention compared with prior art, have the following advantages: one, because base inner wall is the sphere that top has the upper base plate mouth, this base is made up of upper bed-plate and lower bottom base, described upper base plate comprises shoulder on the upper base plate, shoulder under upper base plate waist and the upper base plate, shoulder is protruding for the ball that is complementary with the base inner wall sphere under the described upper base plate, the radius of upper base plate mouth is less than the protruding radius of described ball, be provided with between described upper base plate mouth edge and the described upper base plate waist at interval, no matter how upper base plate rotates, the base inner wall face remains face with upper base plate and contacts, make uplift force stressed evenly, and upper base plate can rotate in the interval of upper base plate mouth and upper base plate waist, and corner can be bigger; Its two owing to be provided with annular oil storage tank, reduced the frictional force between them at described base inner wall; Its three owing to be provided with ring-like seal cover board, prevented that water or dust from entering bearing inside at described base upper surface, cause the corrosion of bearing inside aging; Its four because the contact surface of upper bed-plate and lower bottom base is stepped, improved the sealing of base, prevent that oil spill from going out.
Description of drawings
Accompanying drawing is the structural representation of a kind of large turn angle ball support vertical section of the present invention.
The specific embodiment
Be described in further details below in conjunction with the structure and the use principle of accompanying drawing a kind of large turn angle ball support of the present invention.
As shown in drawings for the structural representation of a kind of large turn angle ball support vertical section of the present invention.A kind of large turn angle ball support of the present invention comprises casing 1 and the base in casing 2, the inwall of base 2 is the sphere that top has upper base plate mouth 23, base 2 is made up of upper bed-plate 21 and lower bottom base 22, upper bed-plate 21 and lower bottom base 22 link together by screw rod 3, in base 2, be provided with upper base plate 4, upper base plate 4 comprises shoulder 41 on the upper base plate, shoulder 43 under upper base plate waist 42 and the upper base plate, shoulder 41 is square tabular on the upper base plate, upper base plate waist 42 is cylindric, under the upper base plate shoulder 43 for the base 2 inwall spheres ball convex that is complementary, upper base plate mouth 23 is circular, its radius is less than the radius of shoulder under the upper base plate 43, is provided with at interval 5 between the edge of upper base plate mouth and upper base plate waist 42.
For the power of reducing friction, be provided with annular oil storage tank 24 at base 2 inwalls.
In order to have prevented that water or dust from entering bearing inside, cause the corrosion of bearing inside is worn out, be provided with ring-like seal cover board 6 at base 1 upper surface.
In order to improve the sealing of base 2, prevent that oil spill from going out, make the contact surface of upper bed-plate 21 and lower bottom base 22 stepped.
When the rack top presses down, upper base plate 4 conducts pressure to base 2 and casing 1, pillar is given in conduction at last, and when the rack middle part was sagging, the side that upper base plate 4 is positioned at rack inside was subjected to downward active force, and shoulder 43 rotates in base 2 under the upper base plate, discharge torque, bearing still is subjected to vertical pressure, because the sphere that base 2 and upper base plate shoulder 43 are complementary, shoulder 43 remains sphere and contacts under base inner wall face and the upper base plate, makes pressure even.When because earthquake or superstructure distortion when producing uplift force, because the sphere that shoulder 43 is complementary under base 2 and the upper base plate, shoulder 43 remains sphere and contacts under upper bed-plate internal face and the upper base plate, makes uplift force stressed even.
