Abstract
The invention relates to an intermediate connecting shaft, which includes a cylinder body, wherein two sections of flat tenons are arranged at the two ends of the cylinder body respectively, and round through holes vertical to the axis of the cylinder body are formed in the side surfaces of the flat tenons. As the flat tenons are machined at the two ends of the intermediate connecting shaft, grooves are machined at the two ends of the to-be-connected shafts, the flat tenons are matched with the grooves, and the cylindrical pins are inserted to the round through holes for fixing, as long as the cylindrical pins are drawn out, the dismounting is completed, the two to-be-connected shafts are not required for axial movement, and the intermediate connecting shaft is convenient to dismount, has a simple structure, and is a novel connecting mode.
Description
Technical field
The present invention relates to a kind of intermediate connecting shaft, belong to the coupling technical field.
Background technique
Being rigidly connected between the diaxon in the machine adopted box coupling more at present, and the shortcoming of box coupling is the dismounting difficulty, need move axially diaxon.And the occasion diaxon that has can not move axially, and its application is restricted.
Summary of the invention
The purpose of this invention is to provide a kind of intermediate connecting shaft, conveniently diaxon is linked together.
The present invention will take following technological scheme: a kind of intermediate connecting shaft, comprise cylindrical body, and be provided with one section flat tenon at the two ends of cylindrical body, said flat tenon side is provided with the round open-work with the cylindrical body axis normal.
Useful benefit of the present invention: the two ends of intermediate connecting shaft are processed flat tenon, and by the two ends machined grooves of coupling shaft, flat tenon and groove match; Inserting the circle open-work with straight pin again fixes; As long as extract straight pin out, two need not moved axially convenient disassembly by coupling shaft during dismounting; Simple in structure, be a kind of novel Placement.
Description of drawings
Fig. 1 is the plan view of a kind of intermediate connecting shaft of the present invention;
Fig. 2 is the plan view of a kind of intermediate connecting shaft of the present invention;
Fig. 3 be the present invention with by the schematic representation that is connected of coupling shaft.
Among the figure: 1, cylindrical body, 11, flat tenon, 12, the circle open-work, 2, straight pin, 3, by coupling shaft I, 4, by coupling shaft II, 5, cotter pin.
Embodiment
As depicted in figs. 1 and 2, a kind of intermediate connecting shaft comprises cylindrical body 1, is provided with one section flat tenon 11 at the two ends of cylindrical body 1, and said flat tenon 11 sides are provided with the round open-work 12 with cylindrical body 1 axis normal.Said round open-work 12 sizes are by the straight pin decision that is mated.
As shown in Figure 3, the flat tenon of the right-hand member of intermediate connecting shaft with matched by the groove of coupling shaft I3, insert with straight pin 2 again and justify open-works, and spacing with cotter pin 5; Equally, the flat tenon of the left end of intermediate connecting shaft with matched by the groove of coupling shaft II4, insert with straight pin 2 again and justify open-works, also use cotter pin 5 spacing.As long as take away cotter pin 5 during dismounting, extract straight pin 2 out and get final product.
Claims (1)
