Abstract
The utility model provides a ball-head rod end knuckle bearing which comprises a ball-head rod and a ball-shell rod, wherein a ball body of the ball-head rod is embedded into a shell of the ball-shell rod; a ball head of the ball-head rod mills an end plane; a check ring is arranged between the ball body of the ball-head rod and the shell of the ball-shell rod; a stopper ring is arranged at a joint of a ball shell of the ball-shell rod and the rod and extends into the shell from the exterior of the shell of the ball-shell rod to be clamped on the ball-head rod and pressed on the check ring, so that the check ring can be prevented from falling off. According to the ball-head rod end knuckle bearing, an oil clearance space between the ball head and the shell is enlarged after the end face of the ball head mills the end plane, so that much lubricating oil can be stored, and lubrication between the ball head and the shell is guaranteed; the check ring is arranged at the joint of the ball head and the rod, leakage of the lubricating oil can be prevented; the stopper ring is arranged outside the check ring, so that the check ring can be prevented from falling off, and long-term lubrication of the bearing can be guaranteed. The ball-head rod end knuckle bearing disclosed by the utility model is reasonable in design, practical in structure, good in lubricating oil storage performance, good in lubricating performance and long in service life.
Description
Technical field
The utility model relates to bearing manufacturing technology field, is a kind of bulb spherical plain bearing rod end specifically.
Background technique
At present, the bulb spherical plain bearing rod end of prior art is generally comprised of ball rod and spherical shell bar, the spheroid of ball rod is set in the housing of spherical shell bar, and relatively rotate in housing, in order to reduce the wearing and tearing between ball rod spheroid and the housing of spherical shell bar, between the spheroid of the ball rod of being everlasting and the housing of spherical shell bar, lubricant oil is set.But the oil clearance between the spheroid of ball rod and the housing of spherical shell bar is less than normal at present, lubricant oil storge quality is poor, in work, usually need to add frequently lubricant oil, unusual very complicated, on some ball rods, be also provided with back-up ring, be set in the housing of spherical shell bar with one of the spheroid of ball rod, but back-up ring easily come off in relatively rotating, cause lubrication failure, cause the damage of bearing.
Model utility content
The purpose of this utility model is to provide a kind of bulb spherical plain bearing rod end, less than normal to overcome the bulb spherical plain bearing rod end oil clearance of prior art, lubricant oil storge quality is poor, need to add frequently lubricant oil, and the back-up ring arranging between spheroid and housing easily comes off or out squeezed at the volley, cause lubrication failure, cause the defect of the damage of bearing.
The purpose of this utility model realizes by the following technical solutions:
A kind of bulb spherical plain bearing rod end, comprise that one end is provided with the externally threaded ball rod of connection and is provided with one end the spherical shell bar that is connected internal thread, housing one end of described spherical shell bar arranges opening, the spheroid of described ball rod is set in the housing of spherical shell bar, the contact of formation face, and with respect to housing, rotate the bulb milling Transverse plane of ball rod, between the housing of the spheroid of described ball rod and spherical shell bar, back-up ring is set, is set in the housing of spherical shell bar with one of the spheroid of ball rod; The spherical shell of described spherical shell bar and bar joint are provided with stopper ring, from the housing of spherical shell bar, extend in housing, are stuck in ball rod and are pressed on back-up ring, in case the coming off of Sealing shield ring.
As the improvement to technique scheme, described stopper ring comprises collar and depression bar, and described collar is stuck in the joint of housing and the bar of spherical shell bar, with it drive fit, described depression bar extend in housing one end from the housing of spherical shell bar, and extends to the other end of housing.
As the improvement to technique scheme, described stopper ring is made by round steel.
As the improvement to technique scheme, described ball rod and spherical shell bar are made by stainless steel.
The utility model has the advantage of: bulb spherical plain bearing rod end of the present utility model, after Bulb Surface milling Transverse plane, the oil clearance space between bulb and housing increases, and lubricant oil storge quality improves, can store more lubricant oil, guarantee the lubricated of bulb and housing; Bulb and bar joint arrange back-up ring, and one is set in housing, can prevent the leakage of lubricant oil, and back-up ring arranges outward after stopper ring, can come off by anti-Sealing shield ring, guarantee the long-term lubricated of bearing.Bulb spherical plain bearing rod end of the present utility model is reasonable in design, structure is practical, and lubricant oil storge quality is good, and greasy property is good, long service life.
