[0002]

2. Description of the Related Art As a centrifugal type governor for a diesel engine, the one shown in FIG. 5 is conventionally known. Here, FIG. 5 is a front view of a centrifugal type governor according to a conventional example, and FIG.
FIG. 7 is a schematic diagram of the centrifugal governor showing a full load operation state, and FIG. 7 is a schematic diagram of the centrifugal governor showing an overload operation state.

As shown in FIGS. 5 to 7, the centrifugal governor 101 comprises a governor lever 105 composed of a first lever 103 and a second lever 104 pivotally supported by a pivot shaft 102 so as to be pivotable. A governor weight 107 is interlockingly connected to the input part 106 of the first lever 103, and a start pin 109 and a rack pin 112 which is a metering tool 111 of the fuel injection pump 110 are connected to the output part 108.
The speed control lever 114 is connected to the second lever 104 through the governor spring 113, and the start pin 109 and the governor spring 113 elastically press the rack pin 112 toward the fuel increase side R, while the governor The governor force G of the weight 107 pushes the rack pin 112 toward the fuel reducing side L via the first lever 103.

The governor lever 1 is caused by the unbalanced force between the elastic pressure on the fuel increasing side R and the pressing force on the fuel decreasing side L.
05 is rocked to move the rack pin 112 by a predetermined amount. Further, the swing contact portion 1 of the second lever 104
15 by the rocking regulation pin 116 at the position corresponding to full load (4/4)
It is configured to accept. In addition, the rocking | fluctuation regulation pin 116 is the fuel regulation tool 117 of the position (4/4) corresponding to full load.
Is functioning as.

As shown in FIG. 6, the torque-increasing device 118 has a case body 119 and a receiving portion 120 of the second lever 104 which projects forward and backward from the tip side of the case body 119.
A torque pin 121 that is capable of elastically contacting the engine and a torque spring 122 (see FIG. 6) that is housed in the case main body 119 and biases the torque pin 121 (see FIG. 6). When the load operating state is shifted to the overload operating state shown in FIG. 7, the torque pin 121 is projected as shown in FIG.
The lever 103 is swung to the fuel amount increasing side R to increase the fuel injection amount and exert the tenacity. Reference numeral 123 in FIG. 5 indicates a governor case, and reference numeral 124 indicates a governor shaft for rotating the governor weight 107.

[0006]

The above-mentioned prior art has the following problems. When the engine is operated for a long period of time, wear occurs on the contact surface 126 of the rocking contact portion 115 and the contact surface 127 of the rocking restriction pin 116 shown in FIG. When such wear occurs, as shown in FIG. 8, during the overload operation in which the torque pin 121 projects, the fuel is injected in excess of the original injection amount for increasing the torque. FIG. 8 shows the state where the torque pin 121 is projected to the maximum,
In such a case, although slightly, the maximum torque-up fuel injection amount Tu is exceeded and the operation is continued. The increase in the fuel injection amount during such overload operation means that not only the maximum torque-up fuel injection amount Tu but also the maximum torque-up torque operation (Tu) from the full-load operation (4/4)
Occurs in the entire torque-up operation range up to.

The fact that the amount of fuel injection increases during overload operation due to wear means that the rocking regulating pin 116 and the rocking contact portion 1 are
Not only the wear of No. 15 but also the wear of the rack pin 112. 9A shows the rack pin position in the initial state without wear, and FIG. 9B shows the rack pin 112.
FIG. 6 is a diagram showing rack pin positions in the case where the wear has occurred or the output portion 108 of the first lever 103 has worn.

As shown in FIGS. 5 and 9, the first lever 103
The output pin 108 and the holding member 129 of the rack pin 1
In the configuration in which 12 is sandwiched and the sandwiching member 129 is constantly pulled by the start spring 109, as shown in FIG. 9B, the contact surface 130 on the increasing side of the rack pin 112 is the first.
Since it is pressed against the contact surface 131 of the lever output portion 108, when wear occurs, the center position of the rack pin 112 shifts to the increasing side by the wear amount d. Therefore, when it should be operated to the full load equivalent position (4/4), it is operated to the position shifted to the increase side. This also occurs in the torque-up operation region, and the fuel injection amount increases.

Further, as shown by e in FIG. 6, the input portion 10 of the first lever 103 to which the governor force G is input.
6 abutment surface 132 and governor sleeve 125 (see FIG. 5)
The position of the rack pin 112 will be shifted to the increasing side even if the contact surface 134 of the is worn. Thus, the contact surface 12 with respect to the fuel limiter 117 at the full load equivalent position (4/4)
Wear of 6/127, abutting surface 130 for the measuring tool 111
The wear of 131 and the wear of the contact surfaces 132 and 134 related to the input portion 106 of the first lever 103 act in the fuel increasing direction, respectively. Therefore, in such a state, the operation of the engine in the torque-up operation range is performed. If continued, more fuel will be injected than the preset injection amount, and there is a problem that harmful substances in the exhaust gas increase.

For this problem, if the length of the torque pin 121 is shortened in anticipation of wear, the inconvenience that the fuel injection amount increases even when the above wear occurs can be solved. However, with this solution, an injection amount smaller than the originally required injection amount is set in the early stage of engine operation in which wear does not occur, and there is a problem that engine stall easily occurs in the overload operation state. .

The present invention has been made in view of the above problems, and an object of the present invention is to provide a centrifugal governor for a diesel engine that can solve the above problems. An example of the specific purpose is as follows. (a) To provide a centrifugal governor for a diesel engine, which is capable of suppressing the operation in a state where the fuel is increased due to wear of the mechanism portion of the centrifugal governor in an overloaded operation state by a simple and inexpensive method To do. The problems of the invention and the means for solving the problems other than those described above will be described in detail in the description in the specification described later.

It is a figure.

As shown in FIGS. 1 and 2, the centrifugal type governor 1 has a swing support shaft 2 which is pivotally supported by a swing support shaft 2.
A governor lever 5 is composed of the lever 3 and the second lever 4, an governor weight 7 is interlockingly connected to an input portion 6 of the first lever 3, and a start spring 9 and a fuel injection pump are provided at an output portion 8 of the first lever 3. A rack pin 12, which is a metering tool 11 of 10, is connected in an interlocking manner, a speed adjusting lever 14 is connected to the second lever 4 via a governor spring 13, and the rack pin 12 is connected to a fuel increasing side by a start spring 9 and a governor spring 13. While the elastic force is applied to R, the governor force G of the governor weight 7 presses the rack pin 12 toward the fuel reducing side L via the first lever 3. The elastic pressure on the fuel increase side R and the fuel decrease side L
The governor lever 5 is swung by an unbalanced force with the pressing force on the rack pin 12 to move the rack pin 12 in a metered amount. In addition, the swing contact portion 15 of the second lever 4 is moved to the full load equivalent position 4 by the fuel regulator 17 including the swing regulating pin 16.
It is configured to receive at / 4.

As shown in FIG. 1, the torque increasing device 18 projects forward and backward from the case main body 19 and the tip end side of the case main body 19 to face the receiving portion 20 of the second lever 4 so that it can be elastically contacted. The torque pin 21 and the case body 19
A torque spring 22 that is housed inside and that elastically biases the torque pin 21. When the engine shifts from the full load operating state to the overload operating state, the torque pin 21 is moved to the first position as shown in FIG. By making the first lever 3 project toward the receiving portion 20 of the second lever 4, the first lever 3 is swung to the fuel increase side R to increase the fuel injection amount and exhibit tenacity.

Further, the torque increasing device 1 is attached to the second lever 4.
When the fuel restrictor 17 receives the second lever 4, the receiving end 20 of the first lever 3 is received by the receiving end 20 of the torque up device 18. The position of the measuring tool 11 operated by the output unit 8 is set to the full load equivalent position (4/4).

The schematic diagram shown in FIG. 1 is different from the configuration diagram shown in FIG. 2 in that the torque-up device 18 is fixed to the third lever 28 supported by the swing support shaft 2 so that the third lever 28 and the The first lever 3 is configured to be operated toward the fuel increase side via the receiving portion 35 of the first lever 3. By adopting this configuration, the start spring 9
The tension of the rack pin 12 causes the start position of the rack pin 12 to increase (S
When operating to t), the third lever 28 can be separated from the first lever 3, and only the first lever 3 can be operated to perform the starting operation.

The characteristic configuration of this embodiment will be described below. In the present embodiment, the torque increasing device 18 prevents the fuel from increasing during overload operation due to wear of the contact surfaces 126 and 127 (see FIG. 6) of the fuel regulator 17.
The tip portion 44 (see FIG. 4) of the torque pin 21 is configured to be easily worn.

FIG. 4 (A1) is a vertical sectional view of the torque increasing device of this embodiment, and FIG. 4 (A2) is a view of the torque increasing device seen from the tip side. As shown in FIG. 4 (A1),
In the torque pin 21 of the present embodiment, the wear resistance is reduced by not heat-treating the tip end portion 44 of the torque pin 21, and the wear adjusting portion 38 is formed by making the tip end portion 44 into a tapered shape. . This wear adjustment unit 3
The length K of 8 is about 0.10 mm to 0.50 mm, preferably about 0.15 mm to 0.20 mm. Figure 4
(B1) and (B2) are diagrams showing another configuration example of the wear adjusting section 38. Similarly, the heat treatment of the tip end portion 44 of the torque pin 21 is abolished, and the tip end portion 44 is provided with a small columnar wear adjusting portion 38.

The operation of the above embodiment will be described. FIG. 1 is a diagram showing a state of a centrifugal governor at the time of maximum torque increase operation in a state (initial state) in which the operating time of the engine is short. After operating the engine for a long time from this initial state, as shown in FIG. 8, when there is no torque-up limiting pin (not shown) that regulates the maximum torque-up amount, the swing-regulating pin 16 is slightly worn due to wear. However, the rack pin 12 may move beyond the maximum torque-up injection amount (Tu). However, in the present embodiment, the wear adjusting portion 38 of the tip end portion 44 of the torque pin 21 comes into contact with the receiving portion 20 of the second lever 4 and wears, so that the influence of the wear of the rocking regulating pin 16 is affected. Can be made smaller. That is, as shown in FIG. 3, the wear adjusting portion 38 (not shown in FIG. 3) causes the first lever 3 to move to the fuel reducing side L.
Therefore, it is possible to suppress the movement of the rack pin 12 toward the fuel amount increasing side R due to the wear of the rocking restriction pin 16.

Further, by adjusting the degree of wear of the wear adjusting portion 38, even if the rocking regulating pin 16 is worn as shown in FIG. ) Can be matched. This correction function also functions in the full torque increase operation region from the full load operation state (4/4) to the maximum torque increase operation (Tu). Further, by experimentally analyzing the wear of the rocking restricting pin 16, the wear of the wear adjusting portion 38 causes the rocking restricting pin 1 in a predetermined operation period of the engine.
It is also possible to set so that the fuel increase caused by the wear of No. 6 is almost completely corrected.

Further, the wear of the contacting surfaces 130 and 131 and the governor force G relating to the measuring tool 111 described in the conventional example.
Even when the contact surfaces 132 and 134 of the input portion 106 of the first lever 103 that are input by the wear are worn, the wear adjusting portion 38 is attached to the tip end portion 44 of the torque pin 21 as in the first embodiment.
By providing the above, it is possible to suppress an increase in fuel injection due to wear of the contact surfaces 130 and 131 and the contact surfaces 132 and 134.
