Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a turning gear device for a diesel engine.

[0002]

[Prior art]

 In order to carry out turning in a diesel engine, the crankshaft is turned by fitting the gears of a gear type flywheel mounted on the crankshaft of the diesel engine with the gears of the electric drive unit and driving them. In such a conventional turning gear device, a pinion gear rotated by an electric device is shifted in its axial direction to engage / disengage a mesh with a gear type flywheel.

In such a conventional turning gear device, it is a normal use method to keep the pinion gear of the drive device out of the engagement with the flywheel except when turning. Conventionally, in fitting / unmating the gears of the drive device with respect to the flywheel during turning, it has been necessary for an operator to simultaneously operate the handle lever and the push button switch for adjusting the position of the gears of the drive device.

FIGS. 3 and 4 show an example of a conventional turning gear device that requires such a handle operation by an operator. 3 and 4, 4-2 is an electric device which is attached to the base plate 4-1. Numeral 4-3 is a pinion gear fitted with a flywheel of a diesel engine gear type at the time of turning, and is slidably supported on the rotating shaft of the electric device 4-2. Reference numeral 4-8 is a bracket provided on the base plate 4-1, and a handle lever 4-7 is swingably supported on the bracket 4-8 by a pin 4-9 and a nut 4-10. A claw 4-11 is attached to the handle lever 4-7, and the claw 4-11 is fitted in the groove of the pinion gear 4-3 so that the handle lever 4-7 is moved around the pin 4-9 as shown in FIG. When the pinion gear 4-3 is oscillated between "on" and "off", the pinion gear 4-3 is shifted along the axis of the electric device 4-2 between the solid line position and the phantom line position, and when the pinion gear 4-3 is in the solid line position, it operates as a flywheel of the diesel engine. Be meshed.

When the electric device 4-2 is stopped, the pinion gear 4-3 does not move in the rotational direction by the key 4-2 attached to the shaft of the electric device 4-2, and therefore the handle lever 4-4. 7 does not move in the "in" direction. The pinion gear 4-3 is rotated by the rotation of the electric device 4-2. In such a conventional turning gear device, at the time of turning, the handle lever 4-7 is operated to engage the pinion gear 4-3 with the flywheel of the diesel engine.

[0006]

[Problems to be solved by the device]

 As described above, the conventional turning device requires the gears to be fitted during turning, but if the turning gear is not disengaged during operation of the diesel engine, the electric device 4-2 will be damaged. Has released the turning gear. Under the above circumstances, it is necessary to fit the turning gear at the time of turning. Therefore, as described above, the operator engaged the turning gear with the handle lever 4-7 and the push button operation.

In order to automate this operation, a device capable of accurately detecting and adjusting each gear position on the flywheel side and the electric device side, and a gear fitting / disengaging device are required. It is difficult to detect and adjust the gear position due to the fact that the position of the teeth of each gear changes with each stop, and the gear on the flywheel side cannot be operated. The fitting and removing work of was not automated. SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems in the conventional device, and an object thereof is to provide a turning gear device for a diesel engine, which enables remote automatic operation.

[0008]

[Means for Solving the Problems]

 Turning transmits power from a drive unit to a flywheel mounted on the crankshaft of a diesel engine to rotate the flywheel. Power transmission at this time is performed by a drive unit via a pinion gear that meshes with a gear-type flywheel. In order to solve the above-mentioned problems in a turning gear device of such a type, the present invention provides a drive device thereof in which an electric device and a pinion gear are fixed and a shaft of the electric device and a shaft end thereof are opposed to each other. It consists of a shaft and electromagnetic clutches attached to the ends of both shafts.

In this case, the pinion gear is supported in a state in which the pinion gear is constantly meshed with a gear type flywheel mounted on the crankshaft of a diesel engine.

[0010]

[Action]

 Since the turning gear device of the diesel engine according to the present invention has the above-described configuration, the electromagnetic clutch is engaged during turning of the diesel engine to connect the shaft of the pinion gear and the shaft of the electric device to the power of the electric device. From the pinion gear to the flywheel. In this case, the electromagnetic clutch and the electric device can be automatically activated by a remote signal.

During operation of the diesel engine after turning, the electromagnetic clutch connecting the shaft of the pinion gear and the shaft of the electric device is disengaged so that excessive force from the flywheel is transmitted and the electric device is not damaged. Keep it.
