Abstract
The utility model discloses a universal ball head bearing. A ball head bar is arranged at the bottom end of a ball head, a ball shell body is arranged on the outer side of the ball head, a circular inner cavity is arranged on the joint of the ball head and the ball shell body, and a circle of steel balls are arranged in the circular inner cavity. The ball shell body is composed of an upper shell body and a lower shell body, a connection base is arranged at the top end of the upper shell body, a sealing ring is arranged at the bottom end of the lower shell, and the upper shell body and the lower shell body are fastened to a whole through bolts. A left locating pin and a right locating pin are arranged on the joint of the upper shell and the lower shell, and an oil filler hole is arranged on the upper left side of the upper shell body. An adjusting washer is arranged on the joint of the upper shell body and lower shell body. The universal ball head bearing is unique in design and ingenious in conception. By installing steel balls inside an assembly inner cavity of the ball head and the ball shell body, the steel balls can roll in 360-degree when the universal ball head bearing runs, and not only can the friction resistance be reduced, but also the rotation flexibility can be improved, and service life of the ball head can also be prolonged at the same time.
Description
Technical field
The utility model relates to a kind of connecting ball head, the definite flexibly bearing with universal ball head of a kind of rotation that says.
Background technique
The bulb bearing is one of common components of mechanical field, be mainly used in the transmission of all kinds of machineries, the link that supports or turn round, existing bulb all is direct by the bulb body and the spherical shell assembling, makes both mutual friction fit, and this traditional ball head structure ball in play head rotates underaction, frictional resistance is large, easily play heat waste and ruin, working life is short, even has influence on the use safety of machinery.
Summary of the invention
The technical problems to be solved in the utility model just provides a kind of bearing with universal ball head that rotates friction that substituted by rolling friction, to reduce the frictional resistance of bulb, improve the flexible performance of rotation of bulb, improve the working life of bulb, strengthen the safety guarantee of machinery.
Scheme of the present utility model comprises bulb, global shell and steel ball, its structural feature is to be provided with ball rod in the bottom of bulb, the outside of bulb is provided with global shell, and the circumference in bulb and global shell junction is provided with the circumferential inner chamber, is provided with all steel balls in the inner chamber of circumferential.Described global shell is comprised of upper shell and lower shell body, and the top of upper shell is provided with the connection pedestal, and the bottom of lower shell body is provided with seal ring, and connecting pedestal can be according to the technical requirements design and installation of equipment, and seal ring can prevent the seepage of bulb lubricant grease.Be respectively equipped with lower connecting plate in the left and right sides of upper-lower casing, have screw on the upper lower connecting plate, upper-lower casing is integrated by bolton, two locating studs about the joint of upper-lower casing is provided with, the upper left side of upper shell is provided with oil hole, and the adjustment packing ring is equipped with in the junction of upper-lower casing.Described ball rod is the drive link of power, can be set as required cylindricality or square configuration, the form structure of global shell can be processed into spheroidal, cylinder form as required, bulb bearing of the present invention can become according to the Demand Design of heavy type or light-duty machinery large-scale, medium-sized, small-sized or miniature type, and the design of the steel bead groove between bulb and the global shell can be processed into bar-shaped trough or circular groove is installed steel ball.
The utility model design is unique, be skillfully constructed, in the assembling inner chamber of bulb and global shell, steel ball has been installed, steel ball can be done the rolling of 360 degree during running, both reduced frictional resistance, improve again the flexibility of rotating, also prolonged the working life of bulb simultaneously, strengthened the safety guarantee of machinery.The movable machinery of the suitable supporting irregular nondirectional guide rod of this product can be done the irregular nondirectional guide rod transmission of 360 degree in the angle of 45 degree, can be widely used in the oil pumping connecting rod guide rod transmission of oilfield exploitation and the transmission device of mine resources screening machinery.Development and use of the present invention have solved thoroughly bulb class machinery sphere and have directly rubbed, and rotate inflexible drawback, have filled up the blank of the domestic and international same industry.
Be described in further detail below in conjunction with accompanying drawing.
