Abstract

The utility model discloses a universal ball bearing, which belongs to the bearing and solves the problems in the prior art that the ball bearing can not rotate flexibly to be adjusted and the threads between the gland and the bearing body can be easily loosened. The universal ball bearing comprises a bearing body and a gland, a ball cup is arranged in the bearing body, a ball groove is arranged in the ball cup, the universal ball bearing is also provided with a non-return steel wire ring, the non-return steel wire ring is provided with a lock hook, the gland is provided with internal threads and a groove, more than one non-return hole is arranged in the groove, the bearing body is provided with external threads and a non-return groove, and the gland is fixedly arranged on the bearing body through threads and is locked by the non-return steel wire ring. The utility model is mainly used in the lifting mechanism, and can also be used in other mechanical equipment requiring the universal ball bearing.

Description

The universal ball end bearing

Technical field

The utility model belongs to a kind of bearing, specifically, relates in particular to a kind of universal ball end bearing.

Background technique

In some lifting structures,, need to adopt a kind of self-regulating bulb bearing in order to regulate and eliminate the error in the mechanism.Existing bulb bearing bulb occurs and rotate and often can't regulate when dumb, and the screw thread between gland and the pedestal is loosening easily, in case loosening situation appears in screw thread, then can influence its stability at work in the processing and assembling process.At present, also there is not a kind of thread looseness that both can avoid between gland and the pedestal, universal ball end bearing that again can its flexibility of regulated at will.

Summary of the invention

Rotate and can't regulate when dumb in order to solve in the prior art bulb bearing, the defective that the screw thread between gland and the pedestal is loosening easily, the utility model provides a kind of universal ball end bearing.

The utility model is achieved through the following technical solutions:

A kind of universal ball end bearing, it comprises pedestal and gland, is provided with the ball bowl in the pedestal, is provided with the ball groove in the ball bowl; Described universal ball end bearing is provided with the non-return steel traveler, and the non-return steel traveler is provided with lock hook; Gland is provided with internal thread and groove, is provided with more than one non-return hole in the groove; Pedestal is provided with outside thread and stop-return slot, and gland is fixed on the pedestal and by the non-return steel traveler by screw thread and locks.

Preferably be provided with six non-return holes in the groove on the gland, six non-return holes evenly distribute; The internal thread of gland is preferably the closely-pitched internal thread, and the outside thread on the pedestal is the closely-pitched outside thread.

Compared with prior art, the beneficial effects of the utility model are: the fine thread connection has been adopted in being connected of gland and pedestal, simultaneously, is provided with the non-return steel traveler, can prevent thread looseness effectively; And rotate when dumb when bulb, can regulate arbitrarily.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

1, gland; 2, ball bowl; 3, non-return steel traveler; 4, pedestal; 5, non-return hole; 6, lock hook; 7, stop-return slot; 8, bulb; 9, groove.

A kind of universal ball end bearing, it comprises pedestal 4 and gland 1, is provided with ball bowl 2 in the pedestal 4, is provided with the ball groove in the ball bowl 2; Described universal ball end bearing is provided with non-return steel traveler 3, and non-return steel traveler 3 is provided with lock hook 6; Gland 1 is provided with internal thread and groove 9, is provided with six non-return holes 5 in the groove 9; Pedestal 4 is provided with outside thread and stop-return slot 7.

When using the utility model, guarantee that the radius of the ball groove in the ball bowl 2 equates with the radius of bulb 8; Bulb 8 is placed in the ball groove, screws on gland 1, the degree of tightness appropriateness is enclosed within non-return steel traveler 3 in the groove 9 of gland 1, makes the lock hook 6 of non-return steel traveler 3 pass the non-return hole 5 on the gland 1 and cut in the stop-return slot 7 that colludes on pedestal 4 and gets final product.
