Abstract

The invention discloses a sealing universal joint, and relates to the field of mechanical transmission, in particular to a universal joint with the good sealing performance. The sealing universal joint comprises a connecting shaft, a base, a spherical pin, a spherical head, a universal shaft, a sealing pad and sealing rings. The connecting shaft is externally connected with the base, and the base is connected with the spherical head; the sealing pad is arranged between the spherical head and the base, and the spherical pin is arranged on the spherical head; and the spherical head is directly connected with the universal shaft, and the sealing rings are arranged between the spherical head and the spherical pin and on the outer portions of the spherical head and the universal shaft. The sealing universal joint has the beneficial effects that when the spherical head rotates, it can be ensured that the sealing performance of the universal joint can be complete, and the extrusion influences of the exterior are avoided.

Description

Sealing universal joint
Technical field:
The present invention relates to mechanical transmission fields, be specifically related to seal universal joint.
Background technique:
Universal joint is the joint of connection two levers, and the common hinge that joint is 90 ° by a pair relative bearing forms, and lever energy is turned to toward any direction, is widely used in now in transmission device.The sealing requirements of some operating environment to universal joint is higher, and existing universal joint ubiquity seals insecure problem, and sealing effect is bad.
Summary of the invention:
The object of the invention is to the defect for prior art and deficiency, provide the sealing universal joint that a kind of structure is simple, reasonable in design, easy to use, it is when bulb rotates, and can ensure that the sealability of universal joint is intact, does not affect by extraneous extruding.
In order to solve the problem existing for background technique, the technical solution used in the present invention is: it comprises coupling shaft, pedestal, ball pin, bulb, cardan shaft, sealing gasket, seal ring; Described coupling shaft and pedestal external, pedestal is ined succession bulb, and be provided with sealing gasket between bulb and pedestal, bulb is provided with ball pin, bulb is directly connected with cardan shaft, and between bulb and ball pin, the outer installment of bulb and cardan shaft has one deck seal ring.
After adopting said structure, beneficial effect of the present invention is: it is when bulb rotates, and can ensure that the sealability of universal joint is intact, does not affect by extraneous extruding.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
Description of reference numerals: coupling shaft 1, pedestal 2, ball pin 3, bulb 4, cardan shaft 5, sealing gasket 6, seal ring 7.
Embodiment:
Below in conjunction with accompanying drawing, the present invention is further illustrated.
In order to make object of the present invention, technological scheme and advantage clearly understand, below in conjunction with the drawings and the specific embodiments, the present invention is further elaborated.Should be appreciated that embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1, this embodiment adopts following technological scheme: it comprises coupling shaft 1, pedestal 2, ball pin 3, bulb 4, cardan shaft 5, sealing gasket 6, seal ring 7; Described coupling shaft 1 is external with pedestal 2, pedestal 2 is ined succession bulb 4, is provided with sealing gasket 6, bulb 4 is provided with ball pin 3 between bulb 4 and pedestal 2, bulb 4 is directly connected with cardan shaft 5, and between bulb 4 and ball pin 3, bulb 4 has one deck seal ring 7 with the outer installment of cardan shaft 5.
When universal joint uses, bulb 4 rotates, due to the setting of seal ring 7, ensure sealability intact between bulb and cardan shaft 5, extraneous extruding impact can not be subject to, the setting of sealing gasket 6, ensure that not having liquid between bulb 4 and pedestal 2 enters, universal joint normally works.
This embodiment, when bulb rotates, can ensure that the sealability of universal joint is intact, does not affect by extraneous extruding.
The above, only in order to technological scheme of the present invention to be described and unrestricted, other amendment that those of ordinary skill in the art make technological scheme of the present invention or equivalently to replace, only otherwise depart from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of right of the present invention.
