Abstract
The utility model relates to a transmission and connection part, in particular to a coupler which comprises a jacket and an inner shaft sleeve with a key groove, wherein the inner shaft sleeve consists of an inner shaft sleeve I and an inner shaft sleeve II; the jacket is available in the following two structures: the jacket consists of a sleeve I and a sleeve II, which engage with the inner shaft sleeve I and an inner shaft sleeve II, respectively; or the jacket has an integrated structure that the inner shaft sleeve and the jacket are connected through a spherical rotating pin, wherein the lower part of the spherical rotating pin is cylindrical, the diameter of the upper part is larger than that of the lower part of the spherical rotating pin, and the two ends of the spherical rotating pin are truncated along the same axis; and a blind hole is formed on the inner shaft sleeve and engages with the cylindrical part of the rotating pin, and a socket is formed on the jacket and engages with the semi-spherical part of the rotating pin. The structure ensures that the rotating pin rotates along the horizontal direction with respect to the inner shaft sleeve and the jacket rotates along the vertical direction respect to the rotating pin, thereby achieving the universal connection.
Description
Technical field:
The utility model relates to a kind of part that is in transmission connection, relate in particular to a kind of coupling.
Background technique:
Coupling is the mechanical parts on a kind of basis of mechanical field, and general power engine mostly links by means of coupling and working machine, so the quality of coupling is also very big to the performance impact of entire machine.And in actual applications, Hooks coupling universal coupling can be realized universal connection, but its installation precision is had relatively high expectations; Drum-shaped tooth type shaft coupling has certain compensation to the diaxon deviation, but is difficult to realize universal connection.Existing in prior technology deficiency that Here it is.
Summary of the invention:
The purpose of this utility model is exactly at the existing in prior technology deficiency, provides a kind of and can realize universal connection, can effectively compensate the coupling of diaxon comprehensive displacement deviation again, and this coupler structure is simple, and is in light weight, long service life.
This programme is realized by following technical measures: this coupling comprises the internal axle sleeve of sleeve and band keyway, described internal axle sleeve is connected by roll pin with sleeve, described roll pin is that the bottom is cylindrical, top is diameter greater than cylinder diameter and along the spherical surface body of same axis two ends cutting, the blind hole that cooperates with the cylindrical part of roll pin is arranged on the described internal axle sleeve, the groove that cooperates with the hemisphere portion of roll pin is arranged on the described sleeve, this structure both can realize that roll pin did the rotation of substantially horizontal with respect to internal axle sleeve, can realize that again sleeve does the rotation of Vertical direction with respect to roll pin, thereby realized universal connection, also can effectively compensate the offset deviation of two between centers.
Above-mentioned internal axle sleeve comprises internal axle sleeve I and internal axle sleeve II, and described sleeve comprises that by bolted sleeve I and sleeve II, sleeve I and sleeve II cooperate with internal axle sleeve I and internal axle sleeve II respectively; Also sleeve can be made of one structure, can select different structural type according to different needs of work.
There is the back-up ring that is mated at above-mentioned sleeve two ends, and can both can prevent the sleeve axial float effectively by back-up ring on sleeve, can guarantee there is enough lubricant oil in the sleeve again.
The beneficial effect of this programme can be learnt according to the narration to such scheme, this coupling is a diameter greater than cylinder diameter and along spherical surface body, the bottom of same axis two ends cutting by top is that columniform roll pin links together internal axle sleeve and sleeve, this structure makes coupling can realize that universal connection also can effectively compensate the deviation of diaxon, installation precision requires low, in light weight and long service life.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.

Among the figure, 1 is back-up ring, and 2 is internal axle sleeve I, and 3 is roll pin, and 4 is sleeve I, and 5 is sleeve II, and 6 is blind hole, and 7 is internal axle sleeve II, and 8 is keyway, and 9 is groove.
Embodiment:
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by embodiment.
A kind of coupling, the internal axle sleeve that comprises sleeve and band keyway 8, internal axle sleeve described in this programme comprises internal axle sleeve I2 and internal axle sleeve II7, sleeve can have two kinds of structures: a kind of sleeve comprises sleeve I4 and sleeve II5 and cooperates with internal axle sleeve I2 and internal axle sleeve II7 respectively, sleeve can also be made of one structure, internal axle sleeve is connected by roll pin 3 with sleeve.Described roll pin 3 is that the bottom is that cylindrical, top is diameter greater than cylinder diameter and along the spherical surface body of same axis two ends cutting, the blind hole 6 that cooperates with the cylindrical part of roll pin 3 is arranged on internal axle sleeve, the groove 9 that cooperates with the hemisphere portion of roll pin 3 is arranged on sleeve, this structure both can realize that roll pin 3 did the rotation of substantially horizontal with respect to internal axle sleeve, can realize that again sleeve does the rotation of Vertical direction with respect to roll pin 3, thereby realize universal connection.At the sleeve two ends back-up ring 1 that is mated is arranged, can on sleeve, offer bolt hole, add lubricant oil to coupling by bolt hole.
