Problems solved by technology

Since the shaft cannot be fixed, it is easy to generate irregular vibration when pulling the shaft, causing its position to change, which brings uncertain factors to the alignment work
The calibration device and the shaft are connected by bolts. When changing positions to measure readings, it is difficult to maintain a uniform force of fastening the bolts each time, resulting in different measurement states of the measuring arm at different positions, resulting in large measurements. error

Embodiment Construction

[0014] Shaftless alignment device without flange, including measuring arm 1, ferrule 2, mounting screw 4 and dial gauge 8. The measuring arm adopts the I-shaped steel structure, which not only ensures the strength, but also reduces its own weight, and also avoids the measurement error caused by the deformation of the measuring arm. The ferrule 2 is composed of the ferrule shell 5 and the inner ferrule 6. The inner ferrule 6 is made of H62 brass. Its purpose is to protect the surface of the shaft from damage. The ferrule 6 is installed in the ferrule shell 5 and fastened by screws. , the ferrule 2 is provided with an opening, on both sides of the opening is fixed with lug plate 7, the mounting screw 4 is mounted on the lug plate on one side of the opening, and the mounting screw 4 is rotated to make it abut against the lug plate on the other side of the opening. ear plate. There are two ferrules 2, which are respectively fixedly connected to one end of the measuring arm 1 at a...

Abstract

The checking center device without the flange axis includes the measure arm, the cutting sleeve, the installment bolt and the dial indicator. The cutting sleeve is made up of the crust and the inner cutting sleeve which is installed in the crust and fixed with it. The open mouth with ear plate fixed on both sides is set in the cutting sleeve. The screw is installed on the ear plate of one side which supports the other ear plate by the rotating installment screw, so the inner diameter of the cutting sleeve is made big. The cutting sleeve is two which are set on one end of the measuring arm in a setting distance; the dial indicator is installed in the other end of the arm. The invention has the simple structure. So the device can promise the round degree of every parts of the axis and the same axis degree.

Description

technical field [0001] The invention relates to mechanical installation, in particular to a flangeless shaft alignment device for installation of ship shafts and rudder systems. Background technique [0002] The on-site installation of ship shafts and rudder systems is a difficult problem in the process of ship construction for shafts without flanges. Since the shafting belongs to the transmission part of large-scale equipment, the firmness of the connection and the alignment of the installation are directly related to the high-efficiency and stable operation. In particular, the dimensional accuracy and alignment requirements of the flangeless shafting are very high. [0003] Due to the lack of strength of the measuring arm in the calibration device used in the past, when the dial indicator is fixed on the measuring arm, the measuring arm often deforms naturally, which brings considerable difficulty to the calibration work. At the same time, during the calibration process,...
