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
The present invention relates to the hydrodynamic test such as boats and ships, seaplane field, be specifically related to a kind of new type water dynamic test trailer guide wheel device.
Background technology
Hydrodynamic test in towing basin is undertaken by the trailer traction motion, and the kinematic accuracy of trailer has directly determined the precision of towing trial, and trailer is most important most crucial equipment in towing basin.The trailer guide wheel device is used for the trailer motion guide, and guide wheel device carries out trailer spacing at the backbone Width, if the bad trailer that will make of guidance quality produces transverse vibration in motion process, directly affect the trailer test accuracy.Traditional trailer guide piece horizontal and vertical degree can't be adjusted, and self-locking performance is poor, and trailer always has a plurality of transverse vibration points in whole motion process, and can't return to virgin state after each detachable maintaining.
Summary of the invention
Purpose of the present invention can't be adjusted for present towing basin trailer guide piece horizontal and vertical degree exactly, self-locking performance is poor, trailer always has a plurality of transverse vibration points in whole motion process, and can't return to the deficiency of virgin state after each detachable maintaining, and a kind of new type water dynamic test trailer guide wheel device is provided.
the present invention is by wheel bracket, the guide wheel bearing, a pair of excentric shaft, a pair of guide wheel, round nut, floor clip, the pair of bearings lid, a pair of end cap, a pair of adjustment packing ring and a pair of felt collar form, be respectively equipped with horizontal projection and vertical protrusion on wheel bracket, difference horizontal and vertical stopper slot on the guide wheel bearing, horizontal projection on wheel bracket and vertical protrusion respectively with the guide wheel bearing on the horizontal and vertical stopper slot match, guide wheel bearing and wheel bracket dock spacing by the stopper slot of horizontal and vertical, excentric shaft and guide wheel bearing are installed by the taper fit face, between excentric shaft and guide wheel, self-aligning roller bearing is installed, round nut and floor clip are used for spacing on excentric shaft of self-aligning roller bearing, self-aligning roller bearing and guide wheel carry out axial limiting by bearing cap and end cap, adjust packing ring and be used for adjusting self-aligning roller bearing in the position of guide wheel center pit, felt collar is arranged in bearing cap.
Advantage of the present invention is: be different from the conventional trailer guide piece, two of left and right guide wheel bearing is made as a bearing, guaranteed the guidance quality of whole guide piece; Wheel bracket has carried out the accurate adjustment of horizontal and vertical when the trailer general assembly, the horizontal and vertical stopper slot all is set on guide wheel bearing and wheel bracket, self-locking performance is good, the precision of whole guide pulley system has had assurance, and after each detachable maintaining, accurate positioning is installed, can returns to the virgin state of trailer; The employing excentric shaft designs, and has well solved the accurate adjustment problem of guide wheel and track side surfaces distance; Can carry out the inspection of horizontal and vertical degree after whole guide wheel device assembling, guide wheel and orbit gap are set to 0.2mm, monitor for a long time unchanged.
