Abstract
The invention belongs to the technical field of transmission shafts, and relates to a connecting structure of a directed swinging transmission shaft. A directed swinging limit device arranged on the transmission shaft adopts one of the following forms: 1, a lining is sleeved outside a transmission shaft and fixed in an installation hole of a housing, the inner surface of the middle of the lining is provided with a bulge which is in contact matching with the transmission shaft; and 2, an inner lining with a special outer surface is sleeved outside the transmission shaft, an outer lining and a shell are sequentially sleeved outside the inner lining, and the shell, the outer lining and the inner lining are symmetrically provided with pin holes, and pin rolls are arranged in the pin rolls. The invention has the advantages that the bulge on the lining or the pin rolls arranged on the shell, the outer lining and the inner lining are used as pivot points, the transmission shaft is supported to swing along the pivot points and has the advantages of large bearing capacity, good structural strength, long service life and flexibility in transmission, and adapts to the connecting structure of the transmission shaft with requirements on the transmission shaft.
Description
Technical field
The invention belongs to the transmission shaft technical field, refer in particular to a kind of linkage structure of directional swing transmission shaft.
Background technique
At present, general gear drive, mostly the location of the gear shaft of requirement installation gear is more accurately good more; So that engagement and power transmission are accurate, but not so still for some gear drive, for example a gear shaft needs small moving; Eccentric shaft needs another gear shaft also to do corresponding cooperation variation thereupon; Otherwise, will occur interfering each other or can not accurately meshing, cause the problem of transmission failure.
Summary of the invention
The linkage structure that the purpose of this invention is to provide a kind of directional swing transmission shaft.
The objective of the invention is to realize like this:
A kind of linkage structure of directional swing transmission shaft comprises transmission shaft, and said transmission shaft is provided with the directional swing limit stoper of transmission shaft, and described directional swing limit stoper is one of following form:
(1) transmission shaft is set with lining outward; Lining is fixed in the mounting hole of shell; The internal surface of described lining is the internal surface of oval column type, and the inward at both ends of the major axis of lining middle part internal surface is provided with bi-side relative with convexity, the minor axis of transmission shaft contact matching and transmission shaft contact matching;
(2) transmission shaft is set with the neck bush that outer surface is a ball-type outward; Neck bush is set with outward axially has the external bushing that matches with outer surface interior cover opening; External bushing is fixed in the mounting hole of housing; Be symmetrically arranged with pin-and-hole on housing, external bushing and the neck bush of center transmission shaft line both sides, pin-and-hole is provided with bearing pin.
The internal surface that above-mentioned convexity extends to form to the two ends of lining is tapered.
The both ends of the surface of above-mentioned shell are arc shaped surface.
The hardness of the hardness of above-mentioned external bushing material≤neck bush material.
The present invention compares the outstanding and beneficial technical effects of existing technology:
1, the present invention makes fulcrum with the bearing pin protruding or that be arranged on housing, external bushing and the neck bush on the lining, and supporting shaft is swung along it, and its bearing capacity is big, structural strength good, long service life, ensuring smooth transmission.
2, the present invention is adapted to transmission shaft is had the transmission shaft linkage structure of swing requirement.

Embodiment
The present invention is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-4:
A kind of linkage structure of directional swing transmission shaft comprises transmission shaft, and said transmission shaft is provided with the directional swing limit stoper of transmission shaft, and described directional swing limit stoper is one of following form:
(1) the transmission shaft 11 outer linings 12 that are set with; Lining 12 is fixed in the mounting hole of shell 13; The internal surface of described lining 12 is the internal surface of oval column type, and the inward at both ends of the major axis of lining 12 middle part internal surfaces is provided with bi-side relative with convexity 122, the minor axis of transmission shaft 11 contact matching and transmission shaft 11 contact matching (referring to Fig. 1, Fig. 2);
(2) be set with the neck bush 22 that outer surface is a ball-type outside the transmission shaft 21; The external bushing 23 that the outer surface with interior cover 22 that being set with outside the neck bush 22 axially has opening matches; External bushing 23 is fixed in the mounting hole of housing 24; Be symmetrically arranged with pin-and-hole on the housing 24 of transmission shaft 21 center line both sides, external bushing 23 and the neck bush 22, pin-and-hole is provided with bearing pin 25, and transmission shaft 21 and neck bush 22 can be with respect to bearing pin 25 swings (referring to Fig. 3, Fig. 4).
The internal surface that above-mentioned convexity 122 extends to form to the two ends of lining 12 is tapered 121, and the middle part of this convexity 122 is as the fulcrum of transmission shaft 11, and transmission shaft 11 can swing up and down (referring to Fig. 2) around this fulcrum.
The both ends of the surface of above-mentioned shell 13 are arc shaped surface 131, so that be arranged on convex shoulder 111 on the transmission shaft 11 along arc shaped surface 131 slide (referring to Fig. 2).
The hardness (referring to Fig. 3, Fig. 4) of hardness≤neck bush 22 materials of above-mentioned external bushing 23 materials, for example: external bushing 23 selects for use copper product or aluminium material or Zinc material to process, and neck bush 22 selects for use stainless steel material or alloy steel material to process.
Applicating example of the present invention; Referring to Fig. 5: when main shaft 33 prized by the lever 31 at its two ends make its do about (perpendicular to paper) have when mobile; Gear 34 on the main shaft 33 also moves up and down thereupon; At this moment, be installed on the transmission shaft 36 of the present invention and also swing up and down around bearing pin 37 thereupon, make gear 34 and driven gear 35 keep engagement driving preferably with the driven gear 35 of gear 34 engagement driving on the main shaft 33; In fact, the leverage 31,32 during this is given an example has also used structural principle of the present invention.
The foregoing description is merely preferred embodiment of the present invention, is not to limit protection scope of the present invention according to this, so: all equivalences of doing according to structure of the present invention, shape, principle change, and all should be covered by within protection scope of the present invention.
