Bearing with universal ball head

Abstract

The invention discloses a bearing with a universal ball head. A ball head rod is arranged at the bottom end of the ball head; a ball shell is arranged at the outer side of the ball head; the circumference of a joint of the ball head and the ball shell is provided with an inner circumferential cavity in which a circle of steel balls is arranged; and the ball shell consists of an upper shell and a lower shell, the top end of the upper shell is provided with a connecting base, the bottom end of the lower shell is provided with a sealing ring, the upper shell and the lower shell are fastened together by using bolts, a joint of the upper shell and the lower shell is provided with a left locating pin and a right locating pin, the left upper side of the upper shell is provided with an oil injecting hole, and the joint of the upper shell and the lower shell is provided with an adjusting washer. The bearing is unique in design and artful in conception; the steel balls are arranged in inner assembling cavities of the ball head and the ball shell to ensure that the steel balls can roll for 360 DEG, so that the frictional resistance is lowered, the flexibility in rotation is improved, and meanwhile, the service life of the ball head is prolonged.

Description

technical field [0001] The invention relates to a connecting ball joint, specifically a universal ball joint bearing with flexible rotation. Background technique [0002] Ball bearings are one of the commonly used parts in the mechanical field. They are mainly used for the transmission, support or operation of various types of machinery. The existing ball bearings are assembled directly from the ball body to the spherical shell, so that the two rub against each other. Cooperate, the rotation of the ball head is not flexible enough in the use of this traditional ball head structure, the friction resistance is large, it is easy to cause heat damage, the service life is short, and even affects the safety of the machine. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a universal ball bearing with rolling friction instead of rotating friction, so as to reduce the friction resistance of the ball head, improve the rota...
