Abstract
The utility model discloses an eccentric shaft which comprises a transmission shaft section and an eccentric shaft section, wherein eccentricity is formed between the eccentric shaft section and the transmission shaft section; the eccentric shaft section and the transmission shaft section are in split structure; the shaft end surface of the eccentric shaft section can slide along the shaft end surface of the eccentric shaft section; the eccentric shaft section and the transmission shaft section are detachably and fixedly connected to form a whole piece; the shaft end of the transmission shaft section is provided with screw holes; the eccentric shaft section is provided with though waist round slots; the eccentric shaft section passes through the waist round slots; and screws screwed into the screw holes and the transmission shaft section are detachably and fixedly connected together; preferably, two screw holes are symmetrically arranged along the central axis of the transmission shaft section; and preferably, two waist round slots are symmetrically arranged along the central axis of the eccentric shaft section. The eccentricity between the eccentric shaft section and the transmission shaft section of the eccentric shaft is adjustable and is convenient to adjust, so that the eccentric shaft is especially suitable for popularization and application in the yarn tension adjusting device of a warp knitting machine.
Description
Technical field
The utility model relates to the transmission shaft in a kind of mechanical transmission mechanism, specifically relates to a kind of eccentric shaft.
Background technique
Existing eccentric shaft comprises propeller section and eccentric shaft part, has throw of eccentric between described eccentric shaft part and the propeller section, and propeller section and eccentric shaft part are made into integration by turning processing.When work, sprocket wheel or belt pulley are installed on propeller section usually, by chain or belt propeller section is rotated, the rotation of propeller section makes with its eccentric shaft part that is made into integration and rotates synchronously, and the rotation with eccentric shaft at last is converted into moving up and down or swinging of other transmission part.
The eccentric shaft of above-mentioned integrative-structure has obtained being extensive use of in mechanical motion, for example be applied in warp knitting machine, in the yarn tension controlling device such as lace machine, the fuel tank main shaft rotates by the propeller section of eccentric shaft on the frame of band or chain drive drive synchronously, the rotation of propeller section is rotated the eccentric shaft part that is made into integration with it simultaneously, the rotation of eccentric shaft part drives the tension rail swing that tension piece is housed on the end by connecting rod, thereby reach the adjusting yarn tension, make tension force keep constant purpose.This yarn tension controlling device, because the throw of eccentric of eccentric shaft is unadjustable, therefore this covering device can not be applied to the type of other different traverses to regulate the yarn tension of different sizes, like this when the yarn lopping weaves, must process the special-purpose eccentric shaft of a cover respectively at the type of different traverses and be used to regulate different yarn tensions, so not only increase cost of production, but also prolonged the manufacture cycle.
Summary of the invention
The throw of eccentric that the technical problems to be solved in the utility model provides between a kind of eccentric shaft part and the propeller section is adjustable, thereby reduces production costs, shortens the eccentric shaft of manufacture cycle.
For solving the problems of the technologies described above, the utility model adopts a kind of like this eccentric shaft, comprise propeller section and eccentric shaft part, has throw of eccentric between described eccentric shaft part and the propeller section, described propeller section and eccentric shaft part are for dividing body structure, the axial end of this off-centre shaft part can be slided along the axial end of propeller section, and described propeller section and eccentric shaft part removably are fixed together and constitute a single piece.
In the utility model, the axle head of described propeller section is provided with screw, be provided with the oval groove that runs through on described eccentric shaft part, described eccentric shaft part removably is fixed together by the screw and the described propeller section of passing described oval groove and be screwed in the described screw.
As a kind of improvement of the present utility model, described screw has two and along the central axis symmetric arrangement of described propeller section, described oval groove has two and arrange along the central axis symmetrical parallel of described eccentric shaft part, and the distance between described two screws equates with distance between the described two oval grooves.
After adopting such structure, because the propeller section of eccentric shaft and eccentric shaft part are for dividing body structure, the axial end of eccentric shaft part can be slided along the axial end of propeller section, therefore the throw of eccentric between eccentric shaft part and the propeller section can be regulated, the throw of eccentric that requires only to need to regulate between eccentric shaft part and the propeller section at different motions gets final product like this, and regulate easy, thereby greatly reduce cost of production, shortened the manufacture cycle.

Embodiment
Referring to Fig. 1 to a kind of eccentric shaft shown in Figure 5, comprise propeller section 1 and eccentric shaft part 2, has throw of eccentric H between described eccentric shaft part 2 and the propeller section 1, described propeller section 1 is the branch body structure with eccentric shaft part 2, the axial end of this off-centre shaft part 2 can be slided along the axial end of propeller section 1, and described propeller section 1 removably is fixed together with eccentric shaft part 2 and constitutes a single piece.
In the utility model, the axle head of described propeller section 1 is provided with screw 1-1, be provided with the oval groove 2-1 that runs through on described eccentric shaft part 2, described eccentric shaft part 2 removably is fixed together with described propeller section 1 by the screw 3 that passes described oval groove 2-1 and be screwed in the described screw 1-1.When regulating throw of eccentric H, only need unscrew screw 3 axial end of eccentric shaft part 2 is slided with respect to the axial end of propeller section 1, when sliding into required throw of eccentric H, tighten screw 3 and get final product.
For make between described eccentric shaft part 2 and the propeller section 1 be connected more reliable, extremely shown in Figure 5 referring to Fig. 3, described screw 1-1 of the present utility model preferably has two and along the central axis symmetric arrangement of described propeller section 1, described oval groove 2-1 preferably has two and arrange along the central axis symmetrical parallel of described eccentric shaft part 2, and the distance between the described two screw 1-1 equates with distance between the described two oval groove 2-1.
Be applied to the yarn tension controlling device of warp knitting machine when eccentric shaft of the present utility model after, because the eccentric shaft part 2 and the throw of eccentric H between the propeller section 1 of eccentric shaft are adjustable, make the type of different traverses only need process the yarn tensions adjusting needs that can satisfy different requirements once the cover eccentric shaft, greatly reduce cost of production, shorten the manufacture cycle, obtained good effect.
