Abstract
The utility model discloses a kind of rigid coupling, comprise a left side half sleeve of, one end external diameter great circle tubular little in one end external diameter and right half sleeve, the end face that described left half sleeve is large with described right half sleeve outer diameter is relative; Described left semicircle cylinder and described right half sleeve are arranged with position correspondence, measure-alike keyway in one end that external diameter is large; Described keyway is built with positioning key; Described positioning key passes through two Cock screws by a described left side half sleeve and the described right side half sleeve connection.Because left half sleeve and right half sleeve are arranged with keyway, be then connected with Cock screw by positioning key, accurate positioning, connect reliable, radial dimension is little, and fabricating cost is low, and bearing capacity is large, is convenient to dismantle two coupling shafts simultaneously.
Description
Technical field
The utility model relates to a kind of rigid coupling, belongs to coupling technical field.
Background technique
The rigid coupling generally adopted at present has box coupling and flange coupling two kinds, and box coupling radial dimension is little, easily manufactures, but dismounting difficulty, flange coupling radial dimension is large, and manufacture cost is high.
Summary of the invention
The utility model object is to overcome above-mentioned deficiency, provides a kind of easy-to-dismount rigid coupling.
The utility model for achieving the above object, adopts following technological scheme: a kind of rigid coupling, and comprise a left side half sleeve of, one end external diameter great circle tubular little in one end external diameter and right half sleeve, the end face that described left half sleeve is large with described right half sleeve outer diameter is relative; Described left semicircle cylinder and described right half sleeve are arranged with position correspondence, measure-alike keyway in one end that external diameter is large; Described keyway is built with positioning key; Described positioning key passes through two Cock screws by a described left side half sleeve and the described right side half sleeve connection.
Further, left coupling shaft is connected with right coupling shaft by two flat keys with described right half sleeve by described left half sleeve.
Further, the width of described positioning key is between 10 ~ 20mm, and height is between 8 ~ 15mm.
The beneficial effects of the utility model are, because left half sleeve and right half sleeve are arranged with keyway, are then connected with Cock screw by positioning key, accurate positioning, connect reliable, radial dimension is little, fabricating cost is low, and bearing capacity is large, is convenient to dismantle two coupling shafts simultaneously.
Accompanying drawing explanation
Fig. 1 is plan view of the present utility model.
Fig. 2 is left view of the present utility model.
Embodiment
As shown in Figure 1 to Figure 2, a kind of rigid coupling, comprise a left side half sleeve 3 of, one end external diameter great circle tubular little in one end external diameter and right half sleeve 1, the end face that left half sleeve 3 is large with right half sleeve 1 external diameter is relative; Left semicircle cylinder 3 and right half sleeve 1 are arranged with position correspondence, measure-alike keyway in one end that external diameter is large; Keyway is built with positioning key 6; Left half sleeve 3 is connected with right half sleeve 1 by two Cock screws 2 by positioning key 6.Left coupling shaft 4 is connected with right coupling shaft 5 by two flat keys 7 with right half sleeve 1 by left half sleeve 3.The width of positioning key 6 is between 10 ~ 20mm, and height is between 8 ~ 15mm.
During installation, left coupling shaft 4 and right coupling shaft 5 span are greater than 5mm.When needs unload bottom left coupling shaft 4 and right coupling shaft 5 simultaneously, only need to turn on Cock screw 2, take out positioning key 6.
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.
