Abstract

The invention discloses an intermittent forward and reverse barring gear driven by a hydraulic cylinder, relates to a barring gear, and solves problems that a barring gear cannot provide a more accurate barring angle in some occasions, is sensitive to axial thermal expansion and can only perform unidirectional automatic barring. The device comprises a reverse barring gear ring, a forward barring gear ring, a forward barring oil cylinder I, a reverse barring oil cylinder I, a forward barring oil cylinder II, a reverse barring oil cylinder II, a forward barring electromagnetic reversing valve and a reverse barring electromagnetic reversing valve, the forward turning gear ring and the reverse turning gear ring are coaxially and fixedly connected to a rotor shaft, the forward barring oil cylinder I and the forward barring oil cylinder II are arranged on the outer side of the forward barring gear ring in the radial direction, the forward barring oil cylinder I and the forward barring oil cylinder II are connected with the forward barring electromagnetic reversing valve, and the reverse barring oil cylinder I and the reverse barring oil cylinder II are arranged on the outer side of the reverse barring gear ring in the radial direction. The device is used for barring.

Description

technical field [0001] The invention relates to a cranking device, in particular to an intermittent forward and reverse cranking device driven by a hydraulic cylinder. Background technique [0002] For units with large resistance torque and large moment of inertia, the rotor needs to rotate at a fixed angle during installation and inspection. In order to facilitate installation, sometimes it needs to rotate intermittently in forward and reverse directions. The traditional barring device generally uses a motor-driven gear reduction device to realize the continuous operation of the barring. After the barring motor stops, the rotor continues to rotate due to inertia, and the angle of the rotor rotation cannot be controlled accurately, which is not conducive to installation and maintenance. In order to have a compact structure, the axial gap between the turning pinion and the turning gear on the rotor of the traditional turning device is about 10mm. In some cases, when the axial...
