Abstract

The utility model discloses an adjustable crankshaft. The adjustable crankshaft comprises a plurality of connecting shafts, a plurality of central shafts and a plurality of eccentric shafts, wherein the central shafts and the eccentric shafts are connected by baffles; the connecting shafts are positioned at the two sides of a columnar structure consisting of the central shafts, the eccentric shafts and the baffles, and the connecting shafts are connected with the baffles; the baffles are connected with the eccentric shafts by screws; the baffles are provided with adjusting strips; the screws penetrate through the adjusting strips and are embedded in the eccentric shafts; the adjusting strips are concave on the surfaces of the baffles. The adjustable crankshaft disclosed by the utility model has the beneficial effects that the eccentric shafts can be moved along the adjusting strips according to the needs, and the applicability of the crankshaft is increased.

Description

Adjustable bent axle

Technical field

The utility model relates to transmission shaft field, particularly a kind of bent axle.

Background technique

Bent axle is the main gearing in engine, by piston rod, is connected with piston, and the torsion by motor conducts mechanical energy to piston, and according to the needs of different engines, the specification of bent axle is also different.In existing bent axle, eccentric shaft is fixed to the distance of central shaft, can not regulate at any time as required, and impact is used.

Summary of the invention

The purpose of this utility model is in order to address the above problem, and has designed a kind of adjustable bent axle.Specific design scheme is:

A kind of adjustable bent axle, comprise coupling shaft, central shaft, eccentric shaft, between described central shaft and eccentric shaft, by baffle plate, be connected, the quantity of described central shaft, eccentric shaft, baffle plate is a plurality of, both sides and described coupling shaft that described coupling shaft is positioned at the column structure being comprised of described central shaft, eccentric shaft, baffle plate are connected with described baffle plate, described baffle plate is connected with described eccentric shaft by screw, described baffle plate is provided with adjustment bar, described screw runs through described adjustment bar and is embedded in described eccentric shaft, and described adjustment bar is depressed in the surface of described baffle plate.

Between described central shaft, coupling shaft, baffle plate for being welded to connect.

Described screw is hexagon socket head cap screw.

Hexagonal nuts one end of described screw embeds in the groove of described adjustment bar.

The adjustable bent axle obtaining by above-mentioned design proposal of the present utility model, its beneficial effect is:

Can make as required eccentric shaft move along adjustment bar, increase the applicability of bent axle.
