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 Novel guide wheel device of hydrodynamic test trailer.
Background technology
Hydrodynamic test in towing basin is moved by trailer traction and carries out, and the kinematic accuracy of trailer directly determines the precision of towing trial, and trailer is most important most crucial equipment in towing basin.Trailer guide wheel device is used for trailer motion guide, and trailer carries out spacing at backbone Width by guide wheel device, if the bad trailer that will make of guidance quality produces transverse vibration in motion process, directly affects trailer test precision.Traditional trailer guide piece horizontal and vertical degree cannot adjust, and self-locking performance is poor, and trailer always has multiple transverse vibration point in whole motion process, and cannot return to virgin state after each detachable maintaining.
Summary of the invention
Object of the present invention cannot adjust for current towing basin trailer guide piece horizontal and vertical degree exactly, self-locking performance is poor, trailer always has multiple transverse vibration point in whole motion process, and the deficiency of virgin state after each detachable maintaining, cannot be returned to, and a kind of Novel guide wheel device of hydrodynamic test trailer is provided.The present invention is by wheel bracket, guide wheel bearing, a pair excentric shaft, a pair guide wheel, round nut, floor clip, pair of bearings lid, a pair end cap, a pair adjustment packing ring and a pair felt collar composition, wheel bracket is respectively equipped with horizontal projection and vertical protrusion, guide wheel bearing is respectively equipped with horizontal and vertical stopper slot, horizontal projection on wheel bracket and vertical protrusion match with the horizontal and vertical stopper slot on guide wheel bearing respectively, guide wheel bearing and wheel bracket are undertaken docking spacing by the stopper slot of horizontal and vertical, excentric shaft and guide wheel bearing are installed by taper fit face, between excentric shaft and guide wheel, self-aligning roller bearing is installed, round nut and floor clip are 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, adjustment packing ring is for adjusting the position of self-aligning roller bearing in guide wheel center pit, felt collar is arranged in bearing cap.Advantage of the present invention is: be different from conventional trailer guide piece, two, left and right guide wheel bearing is made as a bearing, ensure that the guidance quality of whole guide piece; Wheel bracket has carried out the accurate adjustment of horizontal and vertical when trailer general assembly, guide wheel bearing and wheel bracket all arrange horizontal and vertical stopper slot, self-locking performance is good, the precision of whole guide pulley system has had guarantee, and after each detachable maintaining, accurate positioning is installed, the virgin state of trailer can be returned to; Employing excentric shaft designs, and well solves 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, and long-time monitoring is unchanged.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.Fig. 2 is Fig. 1 plan structure schematic diagram.
Embodiment
As Fig. 1, shown in 2, the present invention is by wheel bracket 1, guide wheel bearing 2, a pair excentric shaft 3, a pair guide wheel 4, round nut 5, floor clip 6, pair of bearings lid 7, a pair end cap 8, a pair adjustment packing ring 9 and a pair felt collar 10 form, wheel bracket 1 is respectively equipped with horizontal projection and vertical protrusion, difference horizontal and vertical stopper slot on guide wheel bearing 2, horizontal projection on wheel bracket 1 and vertical protrusion match with the horizontal and vertical stopper slot on guide wheel bearing 2 respectively, guide wheel bearing 2 and wheel bracket 1 are undertaken docking spacing by the stopper slot of horizontal and vertical, excentric shaft 3 and guide wheel bearing 2 are installed by taper fit face, between excentric shaft 3 and guide wheel 4, self-aligning roller bearing is installed, round nut 5 and floor clip 6 are for spacing on excentric shaft 3 of self-aligning roller bearing, self-aligning roller bearing and guide wheel 4 carry out axial limiting by bearing cap 7 and end cap 8, adjustment packing ring 9 is for adjusting the position of self-aligning roller bearing in guide wheel 4 center pit, felt collar 10 is arranged in bearing cap 7.Assembling mode: when this new type water dynamic test trailer guide wheel device uses, first all parts is needed to carry out assembling and positioning, brearing bore and the transition of excentric shaft 5 cylindrical are assembled, by floor clip 6, round nut 5 carries out axial location, the endoporus transition of bearing top circle and guide wheel 4 is assembled, by bearing cap 7, adjustment packing ring 9, end cap 8 carries out axial limiting, wheel bracket 1 is in level, after vertically adjusting, carry out spot welding with cross rail outer face before and after trailer to fix, check errorless after be symmetrically welded, check again after welding heat cooling, ensure installation accuracy, guide wheel bearing 2 and wheel bracket 1 are by horizontal and vertical stopper slot location and installation, install left, the guide wheel 4 of right both sides, guide wheel 4 and track 12(are shown in Fig. 1) after the distance of side adjusted by excentric shaft 3, set nut 12(is shown in Fig. 1) locking, measure the level of whole guide wheel device, vertical and guiding clearance, reach technical requirement.
