Abstract
The utility model discloses a kind of box coupling of improvement, it comprises the first half sleeves, and the second half sleeves, the left half part of the first half sleeves and the second half sleeves is fastened and connected, to form the intermediate portion that intermediate outer is greater than two ends external diameter, the protruding semicircle of the first half sleeves is arranged with two the first pin-and-holes, the second half sleeve projections are circumferentially arranged with four the second pin-and-holes, first pin-and-hole and described second pin-and-hole position correspondence, the bilateral symmetry of intermediate portion places two Semicircular baffles, and the Semicircular baffle of both sides is by bearing pin and fastening nuts.No longer need two coupling shafts to move axially during the dismounting coupling improved, just coupling can be unloaded, make easy removal.Not only can ensure accurate location, also assures that in working procedure and can not produce axial play, make connection more reliable.
Description
Technical field
The utility model relates to a kind of box coupling, is specifically related to a kind of box coupling of improvement, belongs to coupling technical field.
Background technique
The box coupling of current common employing utilizes sleeve and taper pin to be coupled together by diaxon, and this coupling radial dimension is little, easily manufactures, but need move axially cause inconvenient maintenance because being connected axle when shortcoming is mounting or dismounting, thus limit its application area.
Summary of the invention
The utility model object is to overcome above-mentioned deficiency, provides a kind of box coupling of improvement, and the occasion being convenient to can not shift at coupling shaft movement uses.
The utility model for achieving the above object, adopt following technological scheme: a kind of box coupling of improvement, comprise the first half sleeves in semi-circular cylindrical, and left half part is semi-circular cylindrical, right-hand part position the second half sleeves cylindrically, the left half part of described the first half sleeves and the second half sleeves is fastened and connected, to form the intermediate portion that intermediate outer is greater than two ends external diameter, the protruding semicircle of described the first half sleeves is arranged with two the first pin-and-holes, described the second half sleeve projections are circumferentially arranged with four the second pin-and-holes, described first pin-and-hole and described second pin-and-hole position correspondence, the bilateral symmetry of described intermediate portion places two Semicircular baffles, Semicircular baffle described in both sides is by bearing pin and fastening nuts.
Further, described the first half sleeve inner sleeves have the first coupling shaft, and described the second half sleeve inner sleeves have the second coupling shaft; Described first coupling shaft is fixedly connected with the first half sleeves by taper pin, and described second coupling shaft is fixedly connected with the second half sleeves by taper pin.
Further, described first pin-and-hole is identical with described second pin-and-hole diameter.
Further, described bearing pin one end is socket cap, and one end is screw thread.
The beneficial effects of the utility model are, because sleeve part is made up of the first half sleeves and the second half sleeves, then are combined into one by bearing pin, no longer need two coupling shafts to move axially, just coupling can be unloaded, make easy removal during dismounting.The first half sleeves and the second half sleeves are connected as a single entity through two lateral retaining plates by four bearing pins, not only can ensure accurate location, also assures that in working procedure and can not produce axial play, make connection more reliable.

Embodiment
As shown in Figures 1 to 6, a kind of box coupling of improvement, comprise the first half sleeves 1 in semi-circular cylindrical, and left half part is semi-circular cylindrical, right-hand part position the second half sleeves 5 cylindrically, the left half part of the first half sleeves 1 and the second half sleeves 5 is fastened and connected, to form the intermediate portion 8 that intermediate outer is greater than two ends external diameter, the first half protruding semicircles of sleeve 1 are arranged with two the first pin-and-holes 11, the second half sleeve 5 projections are circumferentially arranged with four the second pin-and-holes 51, first pin-and-hole 11 and the second pin-and-hole 51 position correspondence, the bilateral symmetry of intermediate portion 8 places two Semicircular baffles 2, the Semicircular baffle 2 of both sides by bearing pin 3 and nut 4 fastening.
Bearing pin 3 one end is socket cap, and one end is screw thread, can ensure the accurate location of the first half sleeves 1 and the second half sleeves 5, and ensure that in working procedure and can not produce axial play.
The first half sleeve 1 inner sleeves have the first coupling shaft 7, and the second half sleeve 5 inner sleeves have the second coupling shaft 6; First coupling shaft 7 is fixedly connected with the first half sleeves 1 by taper pin 9, and the second coupling shaft 6 is fixedly connected with the second half sleeves 5 by taper pin 9.First pin-and-hole 11 is identical with described second pin-and-hole 51 diameter.
During installation, the first coupling shaft 7 and the second coupling shaft 6 span can not be less than 5mm.When needs unload box coupling, only need to unclamp being threaded of bearing pin 3 and nut 4, extract bearing pin 3 out, the first half sleeves 1 will take off, and then can unload the first coupling shaft 7 or the second coupling shaft 6, easy to operate.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any equivalent replacement done and improvement, all should be included within protection domain of the present utility model.
