But existing this steel ball type safety coupling, was used after a period of time, take fatten apart, thereby very inconvenient, when adjusting peripheral force, device be taken apart, regulated adjusting nut simultaneously, thereby use inconvenient.
Summary of the invention
The present invention is directed to the deficiency of the problems referred to above, propose a kind of convenient steel ball type limiter safety coupling that refuels, conveniently regulates peripheral force.
The present invention is that the technological scheme that solves the problems of the technologies described above proposition is: a kind of steel ball type limiter safety coupling, comprise shell, the first flange, the second flange, centered cover, guide sleeve, butterfly spring, steel ball, steel ball and guide rod, the week that described the first flange is arranged at centered cover, and described centered cover was fixedly connected on shell by fastening piece laterally; And the week that described the second flange is arranged at guide sleeve laterally, and the center of described centered cover, guide sleeve point-blank, and one end of described butterfly spring is provided with adjusting nut, and the other end is provided with spring bearer plate; Butterfly spring, spring bearer plate is slidably connected with shell in week laterally simultaneously, and described guide rod and butterfly spring, spring bearer plate inside are slidably connected, and stretch out shell, described guide rod is provided with the conical surface, described steel ball is arranged in the shrinkage pool of spring bearer plate, and is close to setting with the conical surface of guide rod, and described centered cover inside offers conical surface, described steel ball is stuck in conical surface, and steel ball rolls and is connected mutually with guide rod front end; Also comprise the first oil hole, the second oil hole, adjustment disk, described the first oil hole passes the first flange, centered cover successively, and is communicated in centered cover interior tapered face, and described the second oil hole is arranged on shell, and be communicated with enclosure, and point to little steel ball; Described adjusting nut is in transmission connection by screw thread and adjustment disk screw thread, and adjustment disk stretches out shell, and described adjustment disk positions by movable locating device simultaneously.
Preferred: described the first flange is fixedly connected with by the first fastening screw trip bolt with centered cover.
Preferred: described movable locating device comprises support and the second fastening screw trip bolt, described the second fastening screw trip bolt is connected by threads turn with support.
Preferred: described adjustment disk is screw regulator.
Preferred: described fastening piece is provided with lock nut.
Steel ball type limiter safety coupling of the present invention, compared to existing technology, there is following beneficial effect: 1., owing to being provided with the first oil hole, the second oil hole, therefore only need to coupling, refuel by the first oil hole, the second oil hole, thereby need not take apart, thereby easy to lubricate.2. because described adjusting nut is in transmission connection by screw thread and adjustment disk screw thread, and adjustment disk stretches out shell, described adjustment disk positions by movable locating device simultaneously, therefore in the time of need to adjusting peripheral force, only need stir adjustment disk, thereby rotation adjusting nut, the elastic force of butterfly spring is adjusted, thereby peripheral force is adjusted.
