Novel guide wheel device of hydrodynamic test trailer

Abstract

A novel guide wheel device of a hydrodynamic test trailer comprises a guide wheel support frame (1), a guide wheel support seat (2), a pair of eccentric shafts (3), a pair of guide wheels (4), a round nut (5), a check washer (6), a pair of bearing caps (7), a pair of end caps (8), a pair of adjusting washers (9) and a pair of felt collars (10). The novel guide wheel device of the hydrodynamic test trailer has the advantages that the novel guide wheel device is different from a traditional trailer guide device, one support seat is manufactured to replace a left guide wheel support seat and a right guide wheel support seat, the guidance quality of the whole guide device is ensured, the eccentric shaft design is adopted, so that the problem of accurate adjustment of the distance between the guide wheels and the side face of a track is solved well, horizontal and perpendicular checks can be carried out after the whole guide wheel device is assembled, the gap among the guide wheels and the track is arranged to be 0.2mm in size, and no change exists after long-time monitoring.

Description

technical field [0001] The invention relates to the field of hydrodynamic tests of ships, seaplanes, etc., in particular to a novel hydrodynamic test trailer guide wheel device. Background technique [0002] The hydrodynamic test in the towing pool is carried out by the towing movement of the trailer. The movement accuracy of the trailer directly determines the accuracy of the towing test. The trailer is the most important and core equipment in the towing pool. The trailer guide wheel device is used to guide the trailer movement. The guide wheel device will limit the trailer in the width direction of the main rail. If the guide is not good, the trailer will generate lateral vibration during the movement process, which will directly affect the accuracy of the trailer test. The level and verticality of the traditional trailer guiding device cannot be adjusted, and the self-locking property is poor. There are always multiple lateral vibration points during the whole movement o...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the level and verticality of the current towing pool trailer guide device cannot be adjusted, the self-locking property is poor, the trailer always has multiple lateral vibration points during the whole movement process, and it cannot be restored to the original state after each disassembly and maintenance. , and provide a new type of hydrodynamic test trailer guide wheel device
