Abstract
The utility model belongs to Compressor Technology field, relate to a kind of air compressor crankshaft structure, this crankshaft structure comprises crank pin and equilibrium block, on equilibrium block, wherein offer the bore of carrying out with motor axle journal being connected, its characteristic is: on equilibrium block, be prefabricated with opening slot or the flat hole of kidney-shaped, offer gap in addition to communicate through described opening slot or the flat Kong Eryu bore of kidney-shaped, and thus bore is converted into open shape.The utility model adopts the equilibrium block being prefabricated with opening slot or the flat hole of kidney-shaped, and the gap length offered due to now machining shortens greatly, therefore effectively can improve work efficiency, and can greatly reduce the breakage of cutter.
Description
Technical field
The utility model belongs to Compressor Technology field, relates to a kind of crankshaft structure of air compressor.
Background technique
Existing reciprocating compressor all needs bent axle, to utilize its drive link and then driven plunger, the convert rotational motion of motor is the to-and-fro motion of piston the most at last, thus realizes the compression to air working medium.
Current, the bent axle of reciprocating compressor comprises the components such as axle journal, crank pin and equilibrium block, wherein in order to easy to make, often axle journal and machine shaft are made of one structure, now on equilibrium block, offer bore and axle journal is fastenedly connected, conveniently assemble, existing way is the line of rabbet joint setting out a flat narrow shape on equilibrium block, to facilitate axle journal to intert into bore, and then tighten up the line of rabbet joint with bolt, reach with this object be fastened to by equilibrium block on axle journal.
But, above-mentioned traditional bent axle balance block structure structure of cracking still has worth improvements, and mainly the line of rabbet joint cracking length of flat narrow shape is oversize, and practice shows that this structure is without long processing time, and be very easy to the cutter of wearing and tearing sheet, thus cost of production is higher and manufacturing efficiency is lower.
Summary of the invention
For the deficiency that existing crankshaft counter balance cracking length is long, the utility model proposes a kind of air compressor crankshaft structure, object is effectively shorten the time of cracking, and not easily loss cutter.
The purpose of this utility model is achieved in that a kind of air compressor crankshaft structure, comprise crank pin and equilibrium block, on equilibrium block, wherein offer the bore of carrying out with motor axle journal being connected, it is characterized in that: on equilibrium block, be prefabricated with opening slot or the flat hole of kidney-shaped, offer gap in addition to communicate through described opening slot or the flat Kong Eryu bore of kidney-shaped, and thus bore is converted into open shape.
Above-mentioned equilibrium block is provided with worm structure, adopts screw or bolt to tighten up described gap.
The advantage that the utility model is given prominence to compared to existing technology is: adopt the equilibrium block being prefabricated with opening slot or the flat hole of kidney-shaped, the gap length offered due to now machining shortens greatly, therefore effectively can improve work efficiency, and can greatly reduce the breakage of cutter.
Accompanying drawing explanation
Fig. 1 is that the axle of a kind of air compressor crankshaft structure of the utility model measures intention;
Fig. 2 is a direction view of the embodiment of the utility model shown in Fig. 1.
Embodiment
With specific embodiment, the utility model is further described below, see Fig. 1-2:
A kind of air compressor crankshaft structure, comprise crank pin 1 and equilibrium block 2, on equilibrium block 2, wherein offer the bore 3 of carrying out with motor axle journal being connected, its characteristic is: on equilibrium block 2, be prefabricated with opening slot 4 (as depicted in figs. 1 and 2) or kidney-shaped flat hole (not shown), offer gap 5 in addition to communicate through described opening slot 4 or the flat Kong Eryu bore 3 of kidney-shaped, and thus bore 3 is converted into open shape; It should be noted that, opening slot 4 or the flat hole of kidney-shaped can adopt the mode of the mode of casting or punching preshaped.Equilibrium block 2 and motor axle journal are fastened together to tighten up bore 3 by the utility model, equilibrium block is provided with worm structure, and screw 6 or bolt can be adopted to tighten up gap 4.
Obviously, gap 5 offered by the equilibrium block 2 being prefabricated with opening slot 4 or the flat hole of kidney-shaped, and the length in the gap 5 offered due to now machining is compared with traditional crankshaft counter balance cracking length, and its length is shortened greatly, therefore effectively can improve work efficiency, and the breakage of cutter can be greatly reduced.
Above-described embodiment is only one of preferred embodiment of the present utility model; not limit protection domain of the present utility model according to this; therefore: all various equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by within protection domain of the present utility model.
Claims (2)
1. an air compressor crankshaft structure, comprise crank pin and equilibrium block, on equilibrium block, wherein offer the bore of carrying out with motor axle journal being connected, it is characterized in that: on equilibrium block, be prefabricated with opening slot or the flat hole of kidney-shaped, offer gap in addition to communicate through described opening slot or the flat Kong Eryu bore of kidney-shaped, and thus bore is converted into open shape.
2. a kind of air compressor crankshaft structure as claimed in claim 1, is characterized in that: described equilibrium block is provided with worm structure, adopts screw or bolt to tighten up described gap.
