Figure number and explanation thereof:
1, the first connecting shaft hole；2, left union joint；3, the first fastening bolt holes；4, the first elastic circle body；5, the second elastic circle body；6, right union joint；7, the second circular draw-in groove；8, the first circular draw-in groove.
Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described further.At this it should be noted that be adapted to assist in for the explanation of these embodiments and understand this utility model, but it is not intended that restriction of the present utility model.As long as just can be mutually combined additionally, technical characteristic involved in each embodiment of this utility model disclosed below does not constitutes conflict each other.
With reference to Fig. 1, a kind of shaft coupling that this utility model provides, including left union joint 2 and right union joint 6, it is provided with elastic component between left union joint 2 and right union joint 6, elastic component includes the first elastic circle body 4 and the second elastic circle body 5 from left to right connected, the centrage of the first elastic circle body 4 and the centrage of the second elastic circle body 5 are perpendicular, and the first elastic circle body 4 left end is connected with left union joint 2, and the second elastic circle body 5 right-hand member is connected with right union joint 6.Good flexibility can be produced by elastic component, absorb two axles and the big drift angle deviation produced is installed, thus solve in transmission process, occur that big drift angle deviation causes shaft coupling to be easily damaged and the problem of machine cisco unity malfunction.The cross section of the first elastic circle body 4 is class waist-shaped hole structure, so can reduce the first elastic circle body 4 left side and spacing on the right, the structure of the second elastic circle body 5 is identical with the structure of the first elastic circle body 4, so ensure that the flexibility produced in the course of the work of elastic component, improve the serviceability of shaft coupling.
First elastic circle body 4 is one-body molded with the second elastic circle body 5.Share on one side on the right of first elastic circle body 4 and on the right of the second elastic circle body 5, so can facilitate integrated injection molding, it is ensured that the bending strength of elastic component and fatigue durability intensity, prevent shaft coupling from damaging and ensure the normal work of machine.
Left union joint 2 outer wall is provided with the first circular draw-in groove 8, right union joint 6 outer wall is provided with the second circular draw-in groove 7, first elastic circle body 4 left end is provided with the first hole clipping, second elastic circle body 5 right-hand member is provided with the second hole clipping, first hole clipping is connected on the first circular draw-in groove 8, and the second hole clipping is connected on the second circular draw-in groove 7.So facilitate installation and the maintenance of elastic component.
Elastic component is polyformaldehyde elastic component.The water absorption small size of polyformaldehyde elastic component is stable, tool heat resistanceheat resistant intensity, bending strength, fatigue durability intensity are the highest and wearability, so can improve the service life of elastic component.
Being provided with the first connecting shaft hole 1 in the middle of left union joint 2, left union joint 2 outer wall is provided with at least one first fastening bolt holes 3 being connected with the first connecting shaft hole 1, and the first fastening bolt holes is provided with the first fastening bolt 3.The quantity of the first fastening bolt 3 and position can set according to concrete service condition, can be fixed the first connecting shaft by the first fastening bolt 3, prevent the first connecting shaft from departing from shaft coupling.
