Abstract
The utility model discloses a deviation detection device of dead center position on a diesel engine. The device comprises a first gauge block and a second gauge block that are respectively installed in a blind hole for measuring rotating speed signals on an engine flywheel. A third gauge block is placed on a flywheel casing at the position for assembling a speed sensor. A recording medium is arranged between the flywheel and the flywheel casing. A connecting line of two points made by the first gauge block and the second gauge block on the recording medium is marked and a vertical line between the point made by the third gauge block and the connecting line is marked; the distance between a foot point and one of the two points is measured; and finally, combining with the radius of the flywheel, the deviation angle of an upper dead center is calculated. The detection device only needs three gauge blocks to realize detection and is simple in structure and convenient in use.
Description
Technical field
The utility model relates to a kind of pick-up unit of diesel engine top dead center position deviation detection range.
Background technology
Whether top dead center position accurately is the key point that can electric-control motor efficient operation, in the time of the piston arrives top dead centre, the electric-control system of engine can detect the position signalling that crankshaft sensor sends and determine correct injection advance angle, fuel oil can perfect combustion be so that obtain maximum power in the firing chamber like this, and the harmful exhaust that emits reduces.Yet because there is rigging error in engine in assembling, so often when crankshaft sensor sends the top dead center position signal when, the stroke of piston is not the position that just just in time is in top dead centre, and is perhaps leading, perhaps hysteresis.Electric-control system just can not capture correct moment fuel injected like this, and the work efficiency of diesel motor can be had a greatly reduced quality.For electric-control motor can be worked normally, it is particularly important that the measurement of top dead centre deviation just seems, the most complex structure of top dead centre deviation measurement mechanism that uses uses inconvenient at present.
The utility model content
Technical problem to be solved in the utility model provides a kind of diesel engine top dead center position error measuring means accurate, simple in structure of measuring.
For solving the problems of the technologies described above, the technical solution of the utility model is, diesel engine top dead center position error measuring means, comprise first gauge block and second gauge block, described first gauge block and second gauge block are installed on respectively in the blind hole of measuring tach signal on the engine flywheel, described the 3rd gauge block is positioned over the position of assembling speed sensor on the bell housing, is provided with recording medium between described flywheel and the described bell housing.
As optimized technical scheme, described recording medium is the hard paper.
Owing to adopted technique scheme, diesel engine top dead center position error measuring means, comprise first gauge block and second gauge block, described first gauge block and second gauge block are installed on respectively in the blind hole of measuring tach signal on the engine flywheel, described the 3rd gauge block is positioned over the position of assembling speed sensor on the bell housing, is provided with recording medium between described flywheel and the described bell housing; Make first gauge block and second gauge block stays 2 line on recording medium, do the 3rd gauge block institute stationary point, measure intersection point,, calculate the angle of top dead centre deviation thus again in conjunction with the radius of flywheel to wherein distance to the vertical line between the line; The utility model only needs three gauge blocks, can realize detecting, and is simple in structure, easy to use.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
Embodiment
As shown in drawings, diesel engine top dead center position error measuring means, comprise first gauge block 42 and second gauge block 43, described first gauge block 42 and second gauge block 43 are installed on the blind hole 3 that engine flywheel 2 is used to measure tach signal respectively, bell housing 1 is provided with the 3rd gauge block 41, described the 3rd gauge block 41 is installed on the position of assembling speed sensor on the bell housing, is provided with recording medium between described flywheel 2 and the described bell housing 1, and described recording medium is a hard paper 5.
When engine one cylinder is in top dead center position, first gauge block 42 and second gauge block 43 are positioned over the blind hole 3 that is used for measuring tach signal of engine flywheel, and between flywheel 2 and bell housing 1, place the hard paper, the 3rd gauge block 41 is positioned over the position of assembling speed probe on the bell housing 1, and knock, three some vestiges staying white hard paper according to first gauge block 42, second gauge block 43, the 3rd gauge block 41 after knocking calculate concrete top dead centre misalignment angle.Concrete computing method are: make first gauge block 42 and second gauge block 43 stays 2 line on the hard paper, do 41 stationary points of the 3rd gauge block to the vertical line between the line, the measurement intersection point arrives distance wherein, again in conjunction with the radius of flywheel, calculates the angle of top dead centre deviation thus.
Diesel engine top dead center position error measuring means, comprise first gauge block and second gauge block, described first gauge block and second gauge block are installed on respectively on the engine flywheel, and bell housing is provided with the 3rd gauge block, are provided with recording medium between described flywheel and the described bell housing; Only need three gauge blocks, can realize detecting, it is accurate, simple in structure, easy to use to measure.
Claims (2)
1. diesel engine top dead center position error measuring means, it is characterized in that: comprise first gauge block and second gauge block, described first gauge block and second gauge block are installed on respectively in the blind hole of measuring tach signal on the engine flywheel, described the 3rd gauge block is positioned over the position of assembling speed sensor on the bell housing, is provided with recording medium between described flywheel and the described bell housing.
