Abstract
The utility model discloses a connecting structure of an engine crank shaft and a generator rotor. The connecting structure comprises the generator rotor, a rotor bracket, a spline cushion block, the engine crank shaft and a shaft sleeve, wherein the generator rotor is sleeved on the rotor bracket; the rotor bracket is also together connected with the spline cushion block fixed on the end part of a spline of the engine crank shaft by bolts; the rotor bracket is in a cylinder shape, a through hole is machined at the center of the rotor bracket, and at least one groove is machined at the outer circumference of the rotor bracket; and the outline of the inner circumference of the generator rotor is consistent with the outline of the outer circumference of the rotor bracket. The connecting structure of the engine crank shaft and the generator rotor has the advantages of reliable connection, high concentricity and high transmission efficiency.
Description
Technical field
The utility model relates to a kind of syndeton, the syndeton of especially a kind of engine crankshaft and generator amature.
Background technology
Engine crankshaft in the market is connected with generator amature, is directly to be connected with the bent axle spline through the spline on the rotor field spider, fixes through jump ring, and this structure positioning accuracy is poor, and is loosening easily, be prone to produce the gap, and jump ring comes off easily.
The utility model content
The problem that the utility model will solve is the deficiency that overcomes in the background technology; The syndeton of a kind of engine crankshaft and generator amature is provided; This syndeton; Adopt the generator rotor support structure of special shape, and with the spline cushion block of engine crankshaft end spline fitted, have and connect the advantage reliable, that concentricity is high, transmission efficiency is high.
For addressing the above problem, the utility model is taked following technical scheme:
A kind of engine crankshaft of the utility model and the syndeton of generator amature comprise generator amature, rotor field spider, spline cushion block, engine crankshaft, axle sleeve; Axle sleeve is enclosed within the inboard shaft shoulder place, end of engine crankshaft; Rotor field spider is enclosed within on the excircle of axle sleeve, and is fixed together through screw and the spline cushion block that is enclosed within the engine crankshaft splined end, and the spline cushion block is pressed on the engine crankshaft end through nut; Said rotor field spider is cylindric; The center is processed with through hole, is processed with at least one groove on its excircle, and the inner periphery profile of said generator amature and the outer circumferential profile of rotor field spider match.
An improvement project of the utility model is that cylindrical side Monday of rotor field spider is processed with the shaft shoulder.
A kind of engine crankshaft of the utility model and the syndeton of generator amature; Because generator amature is enclosed within on the rotor field spider; Rotor field spider links together through screw and the spline cushion block that is fixed on the engine crankshaft splined end again; The power of bent axle output passes to the spline cushion block, and the spline cushion block drives rotor field spider through screw and rotates, and then drives the generator amature rotation.Therefore a kind of engine crankshaft of the utility model and the syndeton of generator amature have the advantage that connection is reliable, concentricity is high, transmission efficiency is high.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is that the A of Fig. 1 is to partial schematic diagram.
Embodiment
