Abstract
The utility model relates to a torsion-free and bend-free connector which comprises a middle part, wherein both ends of the middle part are respectively provided with a rotary joint and a fixed joint; the rotary joint is connected with a large screw pin through threads; the middle part and a thrust tapered roller bearing are sheathed between the rotary joint and the large screw pin; the fixed joint is connected with the middle part through threads; and a sealing ring is arranged between the middle part and the rotary joint. When bearing the tension force, the utility model can freely rotate in the positive and reverse directions, can still flexibly rotate under the maximum load and smoothly pass through a tackle for paying off, and is more safe and reliable to use.
Description
Technical field
The utility model belongs to a kind of connector.
Background technology
Connector is that a kind of transmission line tension stringing that is used for connects the anti-specific purpose tool of turning round steel wire rope and towing plate and towing plate and solid conductor, it can be bearing under the situation of tensile force and can positive and negative direction rotating freely, so that eliminate the flywheel moment that produces under the various situations; Connector is except that requiring still to rotate flexibly under maximum load, and also requirement can be passed through releasing pulley smoothly.Traditional bending resistance connector and ∪ type connector can't rotate, can not eliminate lead or the anti-rotation torque of steel wire rope of turning round to limp, can not in time discharge the torsion on the lead, prevent that back twist moment from twisting bad net connector, disappear turn round the bent connector that disappears can be bearing under the situation of tensile force and can positive and negative direction rotating freely, so that eliminate the flywheel moment that produces under the various situations; Traditional rotary connector is the thrust ball bearing of standard because of its inner installation, and the pulling force that can bear is too small can only be little to be with greatly, can not use safely under same specification.
The utility model content
The purpose of this utility model provides a kind of can the rotation flexibly, uses safer the disappearing to turn round the bent connector that disappears.
In order to achieve the above object by the following technical solutions: comprise the middle part of the side, two ends are provided with swivel joint and permanent joint, swivel joint and big screw pin are threaded, the middle part of the side and tapered roller thrust bearing are set between swivel joint and the big screw pin, the permanent joint and the middle part of the side are provided with sealing ring by being threaded between the middle part of the side and the swivel joint.
Described swivel joint front end is hollow multidiameter, be provided with the internal thread hole that matches with big screw pin in the hollow multidiameter, the rear end is a spheroid, end mill becomes a plane behind the spheroid, spheroid inside is milled with arc groove, end on spheroid inside and the arc groove vertical plane is provided with shoulder hole, and the other end is provided with one section unthreaded hole and one section screwed hole.
Be provided with screw pin in the shoulder hole of described swivel joint, be arranged with sheath on the screw pin.
The middle part of the side is provided with high strength internal thread and oil seal groove, and sealing ring is located in the oil seal groove and in swivel joint and matches.
The permanent joint front end is the sphere that five planes of quadrature are arranged, be milled with an arc groove perpendicular to screw pin in the middle of the permanent joint, be conical in the middle of the permanent joint, the permanent joint rear end is provided with perpendicular to the unthreaded hole of flute profile and screwed hole, and described screwed hole is provided with the external screw thread that matches with middle part of the side internal thread.
Be equipped with screw pin in described swivel joint and the permanent joint, be arranged with sheath on the screw pin.
Described big screw pin head is provided with screw.
What the utility model adopted is taper roll bearing, can bear bigger load; Be provided with sheath and avoid preventing that turning round steel cable termina bears local buckling, prolong the steel cable life-span, guarantee that application point is placed in the middle; After the middle part of the side had high strength screw thread and oil seal groove, O RunddichtringO, swivel joint to cooperate, can seal prevented to prevent that lubricating oil from spilling.The utility model still can rotate under maximum load flexibly bearing under the situation of tensile force and can positive and negative direction rotating freely, and can also pass through releasing pulley smoothly, and is more secure and reliable to use.
