Abstract

The invention discloses a turning gear. The turning gear comprises a base, a rotating shaft, a gear, a limiting assembly, a shifting fork assembly and a positioning assembly; the rotating shaft is rotatably arranged on the base; the gear is arranged on the rotating shaft in a sliding and sleeving manner; the limiting assembly is connected with the rotating shaft and the gear so as to limit the gear to rotate relative to the rotating shaft; the shifting fork assembly is rotatably arranged on the base; one end of the shifting fork assembly is rotatably connected to the gear; through rotation of the shifting fork assembly, the gear has a first state in which the gear is meshed with a flywheel of an engine and a second state in which the gear is separated from the flywheel of the engine; and the positioning assembly is connected with the base and the shifting fork assembly, so that the gear is kept in the first state or the second state. The invention provides the turning gear which solves the technical problem that an existing turning gear is not high in working efficiency.

Description

technical field [0001] The invention relates to the field of engines, in particular to a cranking device. Background technique [0002] When assembling and repairing diesel engine parts, or measuring the fuel supply advance angle and crankshaft arm distance difference, it is necessary to adjust the parts to a specific angle before assembling, disassembling or measuring, such as assembling and disassembling the connecting rod, Then the crankshaft needs to be rotated to a certain angle to have room for operation. Since the diesel engine is not started at this time, it is necessary to rotate the crankshaft through the cranking mechanism. However, the current cranking mechanism usually uses a lead screw to drive the linear motion of the driving wheel, which is complicated in structure, inconvenient to use, and affects the work efficiency of the cranking. SUMMARY OF THE INVENTION [0003] The main purpose of the present invention is to provide a cranking device, which aims to ...
