With reference to accompanying drawing 3 and 3-1.3 of two cylindrical cam mechanisms pass through cam pivot shaft 2 and connect.The cam pack (cam mechanism) of Japanese side and the design of Chuan Dong shipbuilding yard adopts Type of Welding, and elder generation's machining cam body is welded to connecting rod subsequently and forms assembly on the cam body during manufacturing.Such method for machining and assembling, the factor of man's activity is many during general assembly, the weld seam power transmission, cause precision low, use reliable not to the utmost; Newly-designed cam pack has adopted the split blade type overlaying structure, and by the machinework of single-piece, high accurate hole, key connect between part, have reduced overall manufacture difficulty.
Electric pushrod 8 is connected by secondary 7 one ends of the spacing attaching parts of V font and connecting rod, in connecting rod pair 7 other ends and the cylindrical cam mechanism 3 in the axial cam connecting rod be connected.
Cylindrical cam mechanism 3 and cam cooperate with roller assembling 6.
With reference to accompanying drawing 2.Roller assembling 6 is made of Roller Shaft 601, roller 602, oscillating bearing 603 and back-up ring 604, and Roller Shaft 601 is by oscillating bearing 603 and back-up ring 604 and roller 601 assembling moulding.That is: roller assembles the 6(roller assembly) compared to the roller assembly of Japanese side and the design of Chuan Dong shipbuilding yard, the application's roller assembly has been installed the sphere oscillating bearing in roller inside.The influence of position deviation when such measure can have been eliminated manufacturing, installation, the design's roller is by the rotation among a small circle of its inner spherical pair, to put contact and change into the line contact, improved the contact line length of roller and chute face, and then reduced contact stress, improved the service life of roller and cam.
Cam mechanism 3 is made of axle sleeve 301, first connecting rod 302, second connecting rod 303, cam 304 and key 305, first connecting rod 302 and second connecting rod 303 are enclosed within on the cam 304 protruding central siphons and adopt key 305 to cooperate with central siphon, and two axle sleeves 301 insert respectively in cam 304 axis holes.
With reference to accompanying drawing 4-Fig. 5-1.Bearing pin 105 is positioned at fixed bearing 103 axis holes by axle sleeve 102 in the permanent seat assembly in the erection support, and two cover plates 104 passes that bearing pin 105 is connected with fixed bearing 103 and bearing pin 105 two ends lay respectively on the support ear of fixed supporting seat 106.Bearing pin 205 in the sliding seat assembly in the erection support is positioned at the rectangle axis hole of expansion bearing 203 by the axis hole in the slide block 204 and slide block 204, two cover plates 204 passes that bearing pin 201 is captiveed joint with expansion bearing 203 and bearing pin 201 two ends lay respectively on the support ear of kinematic support seat 206, and it is interior and be fixed on the support ear that axle inserts bearing pins 201 end grooves with baffle plate 205.Be erection support: spigot surface, stablize panel and be connected to one by bearing and beam, the design of bearing is divided into activity, fixes two types.The sliding seat assembly provides around the rotation of axle and axial support; The sliding seat assembly provides the slippage ability along the beam length direction except providing around the rotation of axle and the axial support time.The flexed plate bearing of Japanese side and the design of Chuan Dong shipbuilding yard is very simple and easy, and bearing does not have sliding sleeve, parts such as cover plate, and the bearing body bottom surface does not have shearing resistance convex cylindrical body simultaneously; The bearing of the application's design has increased above-mentioned link (sliding joint, shearing resistance dome cylinder, the cover plate that adopt high-tensile strength brass and graphite to form in the bearing), cooperates relevant Technology for Heating Processing simultaneously, has realized the reliable use at this position, and is non-maintaining, anti-corrosion function.
With reference to accompanying drawing 6 and Fig. 6-1.Annular boss tensioner cover 407 is enclosed within axle 405 middle parts, two connecting rods 406 are enclosed within the annular boss tensioner respectively and overlap putting of 407 boss both sides, elasticity platen 408 is enclosed within on the axle 405 and elasticity platen 408 taperings are inserted in the annular boss tensioner mantle cavity elasticity platen 408 is fixing, two bearing seats 402 respectively the saturating lid 404 by separately, be installed in axle 405 two ends about bearing 403, two stifles 401 are separately fixed on separately the bearing seat 402.That is: swing arm assembly (connecting rod assembling) bottom bracket axle of Japanese side and Chuan Dong shipbuilding yard design and connecting rod adopt Type of Welding, process axle sleeve during manufacturing earlier, connecting rod is welded to forms assembly on the axle sleeve subsequently.Such method for machining and assembling, the factor of man's activity is many during general assembly, and the weld seam power transmission causes precision low, is difficult for adjusting; The swing arm assembly of the application's design has adopted the split blade type overlaying structure, and by the machinework of single-piece, high accurate hole, elastic compression dish connect between part, have reduced overall manufacture difficulty.
Embodiment 2: with reference to accompanying drawing 7.The track switch of a kind of joint flexible type track switch bending device is linear, comprise track switch fixed end, movable end side line position and movable end linear position, being transition curve between described trouble fixed end 501 and the circular curve, is transition curve between circular curve and the movable end side line position 502.Label 503 is the movable end linear position.That is: Japanese side and Chuan Dong shipbuilding yard track switch have been adopted the linear design of single circular curve.In the use, junction hard spot transition situation can appear in the line; Because of the influence of deck-siding, at open end spigot surface, stabilising surface grinding one's teeth of about 3mm can appear simultaneously.The linear two ends beams of concrete of having considered of the track switch of the application's design influences, the linear array mode that adopts transition curve+circular curve+transition curve of deflection, guaranteed that vehicle impacts gentle the variation at side line turnover track switch, the severe impact that existing product can not occur, reduced the mutual action between circuit and vehicle, be conducive to improve passenger's traveling comfort, shown in Fig. 7.
What need understand is: though above-described embodiment is to the mentality of designing of the present utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to the restriction of the utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection domain of the present utility model.
