Abstract
The utility model relates to a coupling, particularly, a drum-shaped pin coupling. The utility model comprises two inner arc tooth rings, two outer arc tooth sleeves, and two glands, wherein, the two inner arc tooth rings are connected with each other through pairs of a bolt and a nut, the two outer arc tooth sleeves can be installed on a shaft, and the two glands are installed on the inner arc tooth rings. In the utility model, the outer arc tooth sleeves penetrate through the hollow point of each of the glands; drum-shaped pins are placed in holes which are formed in the outer arc tooth sleeves and the inner arc tooth rings; the tooth-shaped part of each of the outer arc tooth sleeves is convex at a central section and forms a drum shape; clearance gaps are arranged between the inner arc tooth rings and the outer arc tooth sleeves; steps for preventing the outer arc tooth sleeves from sliding out are arranged on the inner arc tooth rings; the positions of the steps are correspondingly opposite to the positions of the glands.
Description
The utility model relates to a kind of coupling, especially a kind of cydariform pin coupling.
At present, domestic mechanical transmission connects, and adopts the method for gear coupling mostly, the manufacture cost height, and the aligning angle is minimum, wearing and tearing especially easily when diaxon is installed decentraction, therefore consumption is big, is unfavorable for economic benefit.China Patent No. 90215888.0 provides " a kind of movable coupling ", it is a kind of ball coupling, it is contacted internal tooth and the external tooth interlock that substitutes gear coupling with garden arc groove by ball, though the aligning angle increases, and increases the service life, when installing, ball drops out easily, cumbersome, ball belongs to line with arc groove and contacts, and is easy to generate concave surface.
The purpose of this utility model is for overcoming the deficiency of above-mentioned technology, a kind of surface of contact that increases roller and inside and outside curve bath is provided, improve torque delivery, allowing the big cydariform pin coupling of angle of deflection.
For achieving the above object, the utility model by the following technical solutions:
A kind of cydariform pin coupling, comprise two interior circular arc gear rings that connect by the bolt and nut duplicate invoice, two can be installed in cylindrical curved tooth cover on the axle, two be installed in glands on the circular arc gear ring, cylindrical curved tooth cover vacancy from gland is passed, lay the cydariform pin in the hole that circle-arc tooth cover and interior circle-arc tooth circle form outside, the parts of tooth convexity of cylindrical curved tooth cover is drum type, be provided with the gap between interior circular arc gear ring and the cylindrical curved tooth cover, also be provided with the step that prevents that cylindrical curved tooth cover from skidding off on the interior circular arc gear ring, step position and gland institute holding position respective opposite.
The utlity model has following advantage:
1, low cost of manufacture, and make easily.
2, long service life, its surface of contact is little so resistance is little, makes the hard flank of tooth easily.
3, low to the required precision of diaxon relative mounting positions because it for semi-cylindrical with the cydariform pin contacts is swung mutually and slippage makes things convenient for.
4, transmission efficiency height, energy-conservation.
5, motion is steady, and noise is extremely low, and contact gap is minimum.
6, the aligning ability is good.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with drawings and Examples the utility model is described in further detail:
A kind of cydariform pin coupling, comprise two interior circular arc gear rings 2 that connect by bolt and nut secondary 1, two cylindrical curved tooth covers 3 that can be installed on the axle, two be installed in by bolt in gland 4 on the circular arc gear ring, cylindrical curved tooth cover vacancy from gland is passed, lay cydariform pin 6 in the hole 5 that circle-arc tooth cover and interior circle-arc tooth circle form outside, parts of tooth 7 convexities of cylindrical curved tooth cover are drum type, be provided with gap 8 between interior circular arc gear ring and the cylindrical curved tooth cover, also be provided with the step 9 that prevents that cylindrical curved tooth cover from skidding off on the interior circular arc gear ring, step position and gland institute holding position respective opposite.
