Abstract
The utility model discloses a crankshaft pulley and a turning device of the crankshaft pulley. The crankshaft pulley comprises a cylindrical pulley body and a wheel hub at one end of the pulley body. More than two barring holes are symmetrically formed in the pulley body in the axial direction. The turning device comprises a main rod and two positioning rods, wherein the positioning rods are used for positioning in the axial barring holes. The main rod is provided with a handle end and the positioning rods are perpendicular to the other end of the main rod. Compared with an existing crankshaft pulley with radial barring holes, the crankshaft pulley with the axial barring holes has the advantages of being lower in requirements for operation position and operation direction and wider in application range. The positioning rods can be inserted into the barring holes conveniently by an operator and force application can be achieved by the operator conveniently.

Technical field
The utility model relates to a kind of crank pulley, refers in particular to a kind of crank pulley and hand turning tool thereof with barring hole.
Background technique
Crank pulley is the power resources that connect bent axle and other annex, relies on drivign belt to drive the runnings such as generator, water pump, boost pump, compressor.Shown in Fig. 4 A, Fig. 4 B, it is the structural representation of existing a kind of crank pulley, and this crank pulley is without barring hole, can't jiggering when motor assembling, test, maintenance, and also cause after-sales service inconvenient simultaneously.
In order to overcome the defective that above-mentioned crank pulley without barring hole can't jiggering, a kind of crank pulley with barring hole has appearred, a kind of crank pulley of diesel engine is disclosed such as Chinese utility model patent ZL201220006770.3, it comprises wheel rim and the wheel hub that is set to one, described wheel hub is arranged at an end of described wheel rim, and annular array distribution has some barring holes that radially extend on the described wheel rim.When the needs jiggering, shaft can be passed barring hole in the work, apply the external force rotating pulley, thereby reach the purpose of diesel engine jiggering.Although this crank pulley can by its radially barring hole carry out jiggering, the restriction that when operation is subject to space, inserted link angle is larger, work is made troubles to jiggering.
The model utility content
The technical problems to be solved in the utility model is: a kind of crank pulley and hand turning tool thereof are provided, improve or overcome having the one or more defective that crank pulley exists now when jiggering.
Technical solution of the present utility model is: a kind of crank pulley, this crank pulley comprise belt wheel body cylindraceous and are positioned at the wheel hub of described belt wheel body one end that described belt wheel body is arranged with plural barring hole vertically.
Preferably, in the aforesaid crank pulley, described belt wheel body and wheel hub are integrally formed, and described belt wheel body inboard extends vertically and be arranged with a plurality of cylindrical projection, and described barring hole takes shape in the described cylindrical projection.
Preferably, in the aforesaid crank pulley, the even interval of described belt wheel body is arranged with the barring hole more than four.
The utility model also proposes a kind of hand turning tool for crank pulley, and described hand turning tool comprises mobile jib and two positioning rods that are used for being positioned described axial barring hole, and this mobile jib has holding end, and described positioning rod is vertical at the other end of this mobile jib.
Preferably, the spacing along two axial barring holes of axle center symmetry on the aforesaid hand turning tool for crank pulley, the spacing of described two positioning rods and described crank pulley equates.
Preferably, aforesaid hand turning tool for crank pulley, described mobile jib is seamless steel pipe, described positioning rod is fixedly welded on the other end of this seamless steel pipe.
Characteristics of the present utility model and advantage are: crank pulley of the present utility model adopts symmetrically arranged axial barring hole, has the radially crank pulley of barring hole with respect to having now, the utility model is lower to the requirement of operating position, direction, accommodation is wider, thereby not only the convenient operation person accurately inserts barring hole with positioning rod, and more is conducive to operator's application of force.
