An alignment laser such as a small He-Ne laser or a collimated visible diode laser is required for the alignment of a Pockels cell Q-switch. The capital cost outlay for a laser system versus a set of dial indicators and magnetic bases is the obvious first reason for looking at efficient alignment methods that do not involve laser systems. The laser shaft alignment system with enhanced measuring and reporting The TKSA 41 is an advanced laser alignment solution for achieving accurate shaft alignments. This document only covers horizontal alignment using the Advanced Laser Alignment Application. User Guide Modulator Alignment Procedure 11 Alignment Align the modulator such that the beam enters and exits without any beam distortion.
Alignment Alignment procedures must be followed to prevent unintended contact of rotating parts. Follow coupling manufacturers coupling installation and operation procedures. A unit is in angular alignment when indicator A Angular indicator does not vary by more that. Vertical Correction Top-to-Bottom. Mount two dial indicators on one of the coupling halves X so they contact the other coupling half Y Fig.
Shaft Alignment Procedure Ppt. See step 8 Proper shaft alignment is especially critical when the motor is operated at high speeds. Originally developed by Forethought, who Microsoft bought out, PPT is the worlds most popular presentation file format. If the diameter of the material is too small or the material is too soft, it could. Toe-in or toe-out - the amount by which the wheels are closer or further apart at their front edges than at their rear edges - is adjustable on all cars.
Shaft Alignment 4. Although Omega couplings can withstand gross misalignment, care should be taken for best possible alignment to assure optimum performance. If greater alignment accuracy. So a coupling alignment offset measurement reverse dial indicator or laser system of 0. When paired with a variety of hands-on exercises, the training system creates a complete performance-based course in the maintenance of shaft alignment. Form-Flex Installation Instructions. The alignment needs depend on the connected machinery and the speed of operation.
With the coupling broken, mount the fixture to the stationary shaft or coupling hub. Span the coupling with a rod. Rotate the fixture to Attach the face dial indicator. The dial indicator plunger must be centered for equal positive and negative travel. Attach the rim dial indicator.
Many methods are used to align machinery. The simplest method is using a straight edge to bring the machines into rough alignment. A rough alignment is necessary due to the range limitations of the dial indicators. A popular method used for years and is still in use today is the rim and face method. This method produces acceptable results, but is less accurate than the reverse dial indicator method covered in this application note.
Dial Indicator Alignment Procedure. The procedure for doing reverse dial indicator alignment is not a difficult one. There are several steps which need to be taken for a successful alignment job.
Is the correct alignment of rotating equipment a critical reliability factor in your plant? Would improved or refreshed skills in rim and face shaft alignment methods help with maintenance team confidence and performance? Plant mechanics, millwrights and maintenance engineers are responsible for the health and reliability of rotating equipment. In this course, participants will learn how to accurately align direct coupled machine shafts.
Лейтенант рассказал вам про кольцо? - удивился Клушар, - Рассказал. - Что вы говорите! - Старик был искренне изумлен. - Я не думал, что он мне поверил. Он был так груб - словно заранее решил, что я лгу.
