The utility model discloses the noise is low, the precision is high, operates steadily, and the return stroke clearance is little, and output torque is big, and bearing capacity is high, and long service life can effectively reduce locomotive trouble frequency, improves the locomotive rate of operation.
Description
Technical Field
The utility model belongs to transportation mechanical equipment field especially relates to a taishan type diesel locomotive diesel engine speed control system.
Background
The existing Taishan type diesel locomotive speed control system adopts multi-stage gear combination for speed reduction, and the tooth tips of all stages are in meshing transmission and are dragged by hook-shaped teeth to realize speed control. The disadvantage is that the input shaft and the output shaft are not on the same axis and are not on the same plane. And the volume is bigger, the transmission efficiency is low, the precision is poor. After long-term use, the gear has large meshing clearance and insufficient precision, after long-term use, the tooth tip is seriously worn, slipping can be generated during meshing operation, the phenomenon of tooth loss and rotation loss can be generated under serious conditions, and the stability of the rotating speed of the diesel engine and the accuracy of speed regulation are influenced.
Disclosure of Invention
The utility model provides a bearing capacity is high, operates steadily, efficient, and long service life can reduce locomotive trouble frequency, improves the diesel locomotive diesel engine speed control system of locomotive rate of utilization.
Therefore, the utility model discloses the technical solution who takes does:
a speed control system for diesel engine of diesel locomotive is composed of microcomputer controller, microcomputer speed controller, motor driver, step motor, planetary speed reducer and 24V DC power supply, drive capstan on output shaft of speed reducer, and steel wire hinged to speed-regulating rocker arm of high-pressure pump head of fuel pump.
The utility model has the advantages that:
the utility model has the characteristics of complete machine structure size is little, light in weight, compact structure, and the precision is high, and the return stroke clearance is little, and the output torque is big, and bearing capacity is high, operates steadily, efficient, the noise is low, long service life, non-maintaining etc. The high-precision single-stage transmission device has the advantages of high rigidity, high precision (the single stage can be within 1 minute), high transmission efficiency (the single stage is 97-98 percent), and high torque/volume ratio, can effectively reduce the failure frequency of the locomotive, and improves the operating rate of the locomotive.

Detailed Description
As can be seen from figure 1, the utility model discloses diesel engine speed control system of diesel locomotive is on original microcomputer controller's basis, installs microcomputer speed controller, motor driver, step motor, planetary reducer and 24V DC power supply on the diesel locomotive respectively. The speed reducer is characterized in that a driving winch is mounted on an output shaft of the speed reducer, a transmission steel wire of the driving winch is hinged to a speed regulation rocker arm of a high-pressure pump head of a locomotive fuel pump, a rotating speed control module is arranged in a microcomputer rotating speed controller, the input end and the output end of the microcomputer rotating speed controller are respectively connected with the microcomputer controller and a motor driver, the motor driver is connected with a driving stepping motor, and the stepping motor is connected with and controls the rotating speed of a diesel engine through a planetary speed reducer which outputs coaxially and. The step motor adopts a precise dustproof step motor.
The microcomputer controller sends out a rotating speed control instruction, the rotating speed control instruction is transmitted to the microcomputer rotating speed controller, the rotating speed control instruction is controlled and output to the motor driver through a speed regulation programming module in the microcomputer rotating speed controller, the motor driver realizes power output to control the revolution and the step length of the stepping motor, the rotating torque is coaxially output after being reduced by the speed reducer after the stepping motor rotates, and finally the rotating speed control of the diesel engine is realized through a winch arranged on an output shaft of the speed reducer.
