Vertical Setting Up of Shaft Axes in a Lock Flap at Assembly Stage

Wojciech Anigacz and Maciej Andrzej Jakubiec

Abstract—The following paper presents problems related to vertical setting up of the flap shaft axes. Difficulties in maintaining coaxial relation of the shafts consists, among others, in: lack of variable adjustment and incongruity of standard measurement equipment with this type of measurement tasks. Maintaining the design geometrical conditions is crucial for durability and safety of hydrotechnical structures. The maximum allowable deviation in coaxiality shafts was set at 0.5 mm. Given the extremely difficult conditions of measurement and lack of direct visibility between the measured points retaining a specified range of tolerance was very difficult. With our vast experience of performing measurements and technical service of lock and application of innovative solutions of patents was achieved to the desired accuracy.

Index Terms—Lock flap, measurement, high accuracy requirements, assembly stage.
