Abstract
The utility model relates to a kind of adjustable ball head joint, comprise overcoat, ball head, it is characterized in that in overcoat, be provided with the lining adopting molybdenum alloy metallic material to make, lining is made up of the upper lining and lower lining two-part with hemispherical inner surface, on, certain installing space is had between lower lining, ball head head is positioned at lining, bulb axle portion is stretched out through the bottom of lower lining and overcoat, the top of upper lining is provided with connection gland on the coat, certain gap is had between gland and upper lining, caging bolt is against on lining through its end of gland, adjustment caging bolt, the matching gap of lining and ball head can be changed.Feature is: lining has excellent lubrication, decay resistance, and friction factor is little, does not need any oiling agent of annotating between ball head and lining.Matching gap between lining and ball head can adjust, and to adapt to the load of different gravity, ensures that the flexibility adjustment in use rotated is convenient.
Description
Technical field
The utility model relates to a kind of connected element, particularly a kind of adjustable ball head joint.
Background technique
Existing ball head universal joint, the gap between the bulb part of its ball head and the lining of outside or bearing roller is comparatively accurate and can not adjust, and is usually suitable only for and indoors uses.Use under rugged environment out of doors, be easy to corrosion between the bulb of ball head universal joint and lining or corroded by dust cause lubrication obstacle.Particularly when larger change occurs ball head universal joint for icing or bearing load in the winter time, Action of Gravity Field, on ball head, can affect the flexibility of rotation, reduces the reliability used.
Summary of the invention
It is simple that the purpose of this utility model is to provide a kind of structure, and bearing capacity is strong, is convenient to adjustment, rotates adjustable ball head joint of flexibility and reliability.
Technical solution of the present utility model is: a kind of adjustable ball head joint, comprise overcoat, neck bush, ball head etc., it is characterized in that at overcoat built with the neck bush adopting molybdenum alloy metallic material to make, neck bush is made up of the upper lining and lower lining two-part with hemispherical inner surface, on, certain installing space is had between the end face of lower lining, the bulb position of ball head is embedded in lining, bulb axle portion is stretched out through the bottom of lower lining and overcoat, the top of upper lining is provided with connection gland on the coat, certain gap is had between gland and upper lining, caging bolt is against on lining through its end of gland, adjustment caging bolt, the matching gap of lining and ball head can be changed.
Feature of the present utility model is: lining adopts molybdenum alloy metallic material to make, and have excellent lubrication, decay resistance, and friction factor is little, does not need any oiling agent of annotating between ball head and lining.Matching gap between lining and ball head can adjust, and to adapt to the load of different gravity, ensures the flexibility of rotating.Structure is simple, and adjustment in use is convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in the figure, the ball head joint that the present embodiment adopts is made up of cylindrical jacket 2, the lining be arranged in overcoat, fixing gland 8 on the coat and stainless steel ball head 4.The lining adopting molybdenum alloy metallic material to make is made up of upper lining 1 and lower lining 3 two-part, and the internal surface of upper and lower lining is hemisphere, and has certain installing space each other.Lower sleeve middle position has through hole, and lower lining is arranged in overcoat, and its through hole is just in time relative with the through hole of jacket bottom, and bulb axle portion can be made to stretch out from through hole.The hemispherical inner surface of the head surface and upper and lower lining that are positioned at the ball head of upper and lower lining coincide.Gland 8 is fixing on the coat with screw 6, certain gap is left between gland and upper lining, caging bolt 5 is against on lining through its end of gland, regulate caging bolt, the matching gap between lining and ball head can be changed, thus make ball head joint can rotation nimbly and freely when underloading or heavy duty.7 for being connected to the transmission arm on gland.
