The specific embodiment
Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in the figure, a kind of heel teeth that has the elastic floating cover is protected the footpath reamer, comprise the reamer body and by gear wheel 21, the gear wheel assembly that gear wheel seat 22 constitutes, described reamer body mainly is provided with the body mandrel 11 of tool joint thread 110 by two ends, ring flat-plate 13, mainboard 14, preceding guide strip 12, rear deflector 15, radially water pipe 16, inclination water pipe 17 constitutes, guide strip before described, ring flat-plate, mainboard, rear deflector is fixed on the body mandrel after going to successively, evenly distribute on the circumference on the described mainboard and be no less than three gear wheel seat insert hole 140, the body mandrel was also radially run through at the guide strip rear before described radially water pipe placed, described inclination water pipe places between the gear wheel assembly of mainboard front side and radially runs through the body mandrel, and described gear wheel seat becomes integral body by gear wheel seat insert hole and reamer body are affixed.Correspondence position is respectively equipped with groove 27 on described gear wheel or the pinch roller seat, the closed formation locking of described lock groove steel ball runway groove 213, be equipped with locking steel ball 23 in the locking steel ball runway groove, described gear wheel is set on the gear wheel seat, and by locking steel ball and gear wheel seat axial locking, the macro-axis 221 of described gear wheel seat is socketed with the elastic floating cover, and described elastic floating cover is slidingly matched with the gear wheel endoporus 210 of correspondence position.Two end axles is to evenly being provided with harmomegathus groove 240 up and down for described elastic floating cover, and the opening correspondence of adjacent harmomegathus groove is arranged on elastic floating cover two side ends up and down.Rely on harmomegathus groove 240 elastic floatings to be enclosed within harmomegathus in certain diameter range, in the relative motion of gear wheel and gear wheel seat, adjust the gap between elastic floating cover and gear wheel, the gear wheel seat automatically, make elastic floating overlap relative gear wheel, the speed of related movement of gear wheel seat remains in the basically identical scope.Described harmomegathus groove evenly distributes in the radial position of elastic floating cover, and for guaranteeing that the harmomegathus groove is unlikely to make two continuous harmomegathus groove fractures because of elastic deformation is excessive, described harmomegathus groove depth is at least 1/8th of elastic floating cover width.For further reducing friction factor, reduce calorific value and wear extent, all surface of described elastic floating cover except the harmomegathus groove is coated with the antifriction metal material, as silver etc.
Stud with carbide alloy gauge teeth 211 and carbide cutting tooth 212 on the gear wheel 21 of described gear wheel assembly, the endoporus of gear wheel is provided with locking steel ball runway groove 213, described gear wheel seat is provided with plug pin hole 222, locking steel ball 23 and plug pin 26 are housed in the described plug pin hole, plug pin is used for locking steel ball, and described gear wheel is by axially being connected with gear wheel seat 22 with locking steel ball that locking steel ball runway groove touches.The locking steel ball is gear wheel and gear wheel seat location, and the gear wheel seat is packed into behind the wheel seat hole, welds with arc welding again.Constitute bearing bore between described gear wheel seat and the gear wheel, its joint portion is provided with bearing sealed ring 25.Bearing sealed ring is that the bearing of gear wheel and gear wheel seat provides the annular seal space that lubricant grease exists.The body mandrel is a central axis, and its two ends are provided with tool joint thread, can be arranged to male thread or box thread as required, jointed rod when being used for operation.The gear wheel axis is parallel with the reamer body axis, so the heel teeth of gear wheel is the maximum outside diameter of whole reamer.The gear wheel heel teeth has determined counter bore diameter at the maximum outside diameter of gear wheel.After the gear wheel assembly lost efficacy owing to reasons such as wearing and tearing, the gear wheel seat can be broken away from the reamer body with methods such as ARC CUTTING after, weld gear wheel assembly new product again, continue to use, the reamer body is reusable.Cutting teeth is the main cutting element of reamer, and gauge teeth is that counter bore diameter is provided safeguard, and plays the assisted machining effect.
In gear wheel assembly when assembling, install elastic floating cover 24 earlier, sealing ring 25, after gear wheel seat 22 is packed into, by the plug pin hole 222 locking steel ball 23 of packing into, plug pin 26 pack into plug pin hole 222 and weld after, promptly locked locking steel ball 23 in its runway.After locking steel ball 23 is packed into, locked the axial location of gear wheel 21 with gear wheel seat 22.Sealing ring 25 provides sealing function for the bearing bore of gear wheel and gear wheel seat formation, and bearing bore and outside mud that it will be equipped with lubricant grease separate, and ensure bearing operate as normal under the condition of good lubrication.Gauge teeth has determined the counter bore diameter of reamer at the maximum gauge of gear wheel, change gauge teeth and just can change counter bore diameter at the maximum gauge of gear wheel, in other words, change the maximum gauge of gear wheel integral body, just counter bore diameter can be changed, therefore, the gear wheel of different-diameter grade can be made, utilize same body, realize multistage reaming.The conveyance conduit hole be on than the basis of minor diameter prebored hole step by step counterboring form, after finishing the one-level counterboring, if gear wheel component failures or basic the inefficacy, removable lower tooth wheel assembly, continue to use existing reamer body, install and weld than other gear wheel of major diameter level, carry out the next stage ream operation.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
