Description
Technical field
The utility model belongs to electronic controlled diesel signals collecting assistant tool field, is specifically related to the angular signal dish be configured on crankshaft of diesel engine.
background technique.
At present, the deterioration of earth environment receives much concern as a global problem, and China requires also more and more higher to the emission level of diesel engine, also more and more stricter to the waste gas harmful substance content requirement in air to diesel emission.
Modern diesel engine, in order to reduce the discharge of harmful gas, adopts electric control fuel system accurately control combustion process, thus reduces the discharge amount of harmful gas.The based sources that electric control fuel system accurately controls is in the precision of signals collecting, and existing signals collecting situation is as follows:
(1), processing signal tooth on flywheel: the cost of this kind of mode is high, and minimum outer diameter has 350mm, and the thickness of tooth can reach 18mm; Material because of flywheel is HT250, can only go out signal teeth by machine tooling, and long processing time, efficiency are low, cost is high; Signal teeth on flywheel is mounted in flywheel casing, and because avoiding the signal disturbing of the starting gear ring on flywheel, the external diameter of signal teeth is larger than the external diameter of starting gear ring, directly causes the enlarged diameter of flywheel casing, and the weight of diesel engine and cost are increased; Pick-up transducers is arranged on flywheel casing, because the transition added between flywheel casing with body connects, adds a dimensional chain, causes the precision of collection poor.
(2), signal panel are adopted: the diameter of existing signal panel is comparatively large, Heavy Weight, processed complex, and the cumulative limit assembled with crank pulley is large, causes the precision of signals collecting poor, and occupies the space outerpace of diesel engine.
Model utility content
For solving that the cost that existing diesel electric control fuel system signals collecting exists is high, signal panel diameter large, assembling accumulated tolerance is large and the defect such as larger that takes up room, the utility model devises the angular signal dish be configured on crankshaft of diesel engine.
Be configured in the angular signal dish on crankshaft of diesel engine, described signal panel 1 are ringwise discoid, one section of circular arc radial protrusion on signal panel 1 outward edge has the first signal teeth 2, on the outward edge of residual signal dish 1, radial direction is equidistantly distributed with secondary signal tooth 3, in the channel form of caving between adjacent two secondary signal teeth 3;
On described signal panel 1, circumference is evenly equipped with the mounting hole 5 of more than three, and the signal panel 1 wherein between two adjacent mounting holes 5 are provided with positioning hole 4;
The external diameter of described signal panel 1 is 130mm-155mm.
During work, be inserted with angular positioning pin 7 in positioning hole 4, fastening screw trip bolt 8 passes mounting hole 5, is connected with the equilibrium block of bent axle 6 near output end, is fixed on bent axle 6 by signal panel 1.
The external diameter of described signal panel 1 is 147mm.
The thickness of described signal panel 1 is 5mm.
Described mounting hole 5 is the counterbore of 90 ° of cone angles, and described positioning hole 4 is waist shaped hole and the long axis direction of positioning hole 4 is radially arranged.
The axle center of described positioning hole 4 and the axle center of mounting hole 5 are positioned at circumferentially same.
The material of described signal panel 1 is not easily magnetized low carbon steel.
Advantageous Effects of the present utility model:
(1), the utility model volume is little, lightweight, and thickness only has 5mm, and external diameter is 147mm, 0.5mm larger than the radius of crankshaft counter balance, the signal waveform signal stabilization measured by experiment, reliable.
(2), be arranged on the crankshaft counter balance of diesel engine during the utility model real work, signals collecting sensor can be arranged on body, reduces the cumulative limit in assembly process, effectively improves the precision of signals collecting, and do not take space outerpace, compact structure.
