Abstract

The invention relates to a handheld turning gear, and relates to the technical field of overhaul devices. The handheld turning gear comprises a motor, a driver, a handle and a speed reducer, wherein the driver is arranged on the motor, the handle is electrically connected with the drive so as to control the motor to positively and negatively rotate, the speed reducer is arranged on one side of themotor and is used for increasing the output torque of the motor, the speed reducer is coaxially fixed to an output shaft of the motor, a mounting mechanism is arranged between the motor and the speedreducer, the mounting mechanism comprises a blind flange which is arranged on one side, which is close to the output shaft, of the motor, locking blocks which are arranged on the blind flange in a sliding mode and are located on both sides of the output shaft, driving pieces which are arranged on the blind flange and are used for driving the locking blocks to slide and a locking ring which is arranged on the speed reducer, the locking blocks are in inserting matching with the locking ring during sliding, and the sliding direction of the locking blocks is perpendicular to the axial direction of the motor. The handheld turning gear has the advantage that the mobile transportation and disassembly and assembly workload is reduced so as to improve the maintenance efficiency.

Description

technical field [0001] The invention relates to the technical field of maintenance devices, in particular to a hand-held turning device. Background technique [0002] At present, cranking refers to turning the motor a few times with manpower before starting the motor to judge whether the load driven by the motor (that is, the mechanical or transmission part) is stuck and the resistance increases, so that the motor will not be damaged. The starting load becomes larger and damages the motor. [0003] The crank mechanism is mainly used for assembly, debugging and maintenance of diesel engines. At present, most small and medium-sized diesel engines are seldom equipped with a dedicated turning mechanism, and generally directly use the flywheel of the diesel engine for turning, which is labor-intensive. Therefore, the operator generally uses an electric barring machine to perform barring during maintenance. The electric barring machine is an electric motor with a large torque. W...
