Description
Technical field
The utility model relates to a kind of coupling, specifically is a kind of radially stepless adjustable coupling, is mainly used in the connection between the diaxon that the radial deflection distance is big and surrounding space is less again.
Background technique
The existing coupling that can compensate diaxon radial deflection amount mainly contains oldham coupling, quincunx coupling and gear coupling or the like, and its shortcoming is: oldham coupling is not suitable for running up, and the side-play amount that these coupling compensated is all very little.Though cross-pin coupling also can replenish bigger radial deflection amount in addition, it can take bigger space (especially axial distance is big) in the running, is not suitable for surrounding space smaller applications occasion.
Summary of the invention
The purpose of this utility model just provides a kind of radially stepless adjustable coupling, and is very little or take problem than large space to solve compensation diaxon radial deflection amount that existing coupling exists.
The technical solution of the utility model is: comprise flange, connecting rod, land, single shaft and twin shaft, be equipped with axial attachment hole at the place of keeping to the side of flange and land, place, close two ends at connecting rod is equipped with and the homoaxial attachment hole of above-mentioned attachment hole, an end of each fixedly connected single shaft in each attachment hole on two relative flanges, an attachment hole of the other end of single shaft and a connecting rod is rotationally connected; Described land is between described two flanges, and the middle part of twin shaft is fixedly connected in the attachment hole of land, and the two ends of this twin shaft are rotationally connected with another attachment holes of described two connecting rods respectively; On described single shaft and twin shaft, be equipped with oiling mechanism.
Attachment hole on described flange and the land and twin shaft are three, and are uniformly distributed along the circumference; Connecting rod and single shaft that these land both sides connect respectively are three.
Be rotationally connected by bearing between described connecting rod and single shaft and the twin shaft.
Described bearing is a drawn cup needle roller bearing.
Described oiling mechanism is made up of the press-fit priming cup of oil hole and outer end thereof.
The utility model utilizes the transmission of two-stage parallel four-bar linkage, can compensate with the side-play amount of two coaxial two axles that are connected of flange to reach 0~2 times of connecting rod, and can electrodelessly adjust, and volume and occupation space is less.

Embodiment
Referring to Fig. 1~Fig. 8, the utility model comprises flange 2 and 9, connecting rod 7, land 1, single shaft 3 and the twin shaft 6 at two ends, flange 2 and 9 and the place of keeping to the side of land 1 be equipped with three axial attachment holes that are uniformly distributed along the circumference 21,91 and 11, place, close two ends at every connecting rod 7 is equipped with and the homoaxial attachment hole 71 of flange, a be rotationally connected attachment hole 71 of a connecting rod 7 of an end of each fixedly connected single shaft 3 in each attachment hole on two flanges, the other end of single shaft 3; Land 1 is between two flanges, and the middle part of twin shaft 6 is fixedly connected in the attachment hole 11 of land 1, and the two ends of this twin shaft 6 are rotationally connected with another attachment holes 71 of described two connecting rods 7 respectively; Be equipped with oiling mechanism 4 on described single shaft 3 and twin shaft 6, this embodiment's oiling mechanism 4 comprises the press-fit priming cup of oil hole and outer end thereof.
This embodiment's twin shaft 6 is three, and is uniformly distributed along the circumference; Connecting rod 7 and single shaft 3 that these land 1 both sides connect respectively are three.
Be rotationally connected by drawn cup needle roller bearing 8 between described connecting rod 7 and single shaft 3 and the twin shaft 6.
Working principle of the present utility model is as follows:
As can be seen from Figure 9, the utility model is actually by two parallel four-bar linkages to be formed, wherein:
First parallel four-bar linkage is by pivoted arm AB (being the radius of flange 2), connecting rod BC (being the connecting rod 7 of land 1 one sides), pivoted arm CD (being the radius of land 1) and connecting rod DA (being connecting rod 7 combinations of homonymy);
Second parallel four-bar linkage is by pivoted arm DC (being the radius of land 1), connecting rod CE (being the connecting rod 7 of land 1 opposite side), pivoted arm EF (being the radius of flange 9) and connecting rod FD (being connecting rod 7 combinations of homonymy).
Its transmission principle is: when pivoted arm AB rotated around immovable point A, pivoted arm CD will rotate around the round dot D that floats with identical turning to rotating speed, and pivoted arm EF also can center on fixedly round dot F rotation with same turning to rotating speed simultaneously.
The determining of round dot D floats: when above-mentioned two parallel four-bar linkage independences, the round dot D that floats can be the center of circle with A respectively, and DA is on the round I of radius with F to be the center of circle, and FD is that the round II of radius is upward mobile.Because CD is the coenosarc of two parallel four-bar linkages, therefore after round dot A (axle center of flange 2) and round dot F (axle center of flange 9) are determined, the intersection that the D point can only be fixed on round I and justify II, i.e. D point or H point.
Because what D was ordered floats, so the F point is being the center of circle with the A point, 0~2DA is that the round III area of radius is interior when a bit mobile arbitrarily, and circle II always intersects with round I, the formation Transmitted chains.Therefore the spacing of AF can steplessly be adjusted.Scope is at 0~2 times length of connecting rod, direction in the plane of vertical flange axis each to.
