Abstract
The utility model discloses a worm cam transmission mechanism, comprising a worm cam, roller gears, a driving shaft, a driven shaft, a scale division component and a positioning part. The worm cam transmission mechanism is characterized in that the driving shaft is arranged on the inner socket of a bearing with a screw thread. The inner socket of the bearing is arranged on an outer socket of an eccentric bearing with a screw thread. The driven shaft is arranged on the inner socket of the bearing with the screw thread. A positioning piece with a plurality of holes, a bearing cap and screws are used for fixing the inner socket of the bearing. The driven shaft of the utility model can be adjusted in four directions of up, down, left and right. The driven shaft can be adjusted in two directions of front and rear. The utility model has the advantages of easy fabrication, convenient adjustment. Lower machining precision of components and lower expense cost in the whole service life.
Description
The utility model relates to a kind of worm-cam---roller-dear, worm and wheel, driving mechanisms such as gear and gear, particularly a kind of interrupted division driving mechanism.
It is general that worm-cam---roller-dear interrupted division driving mechanism all partly is made up of casing, worm-cam, roller-dear, driving shaft, driven shaft, bearing, bearing support and indexing mechanism etc.But, such driving mechanism is in order to reach worm-cam on the driving shaft with the roller-dear quality of fit requirement on the driven shaft, very high to each other required precision of part of forming driving mechanism, for this reason, to the design and the high requirement of process for machining and manufacturing proposition of other part.And, the debugging work of total process of assembling has been brought certain difficulty.Driving mechanism is through after the running of certain hour, wearing and tearing have been produced, because the position of driving shaft and driven shaft is difficult for adjusting, bring difficulty to maintenance, need often to change other parts, reduce the working life of driving mechanism, improved the expense cost of driving mechanism in whole lifetime.
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of and can regulate driving shaft, the interrupted division driving mechanism of driven shaft position reaches the required precision that worm-cam cooperates with roller-dear, and easy to adjust, reduced the processing request of parts in addition simultaneously.Maintenance at ordinary times, easy maintenance is simple.
The utility model it by casing, snail body cam, roller-dear, driving shaft, driven shaft, bearing, bearing support, indexing mechanism and location are partly formed, it is characterized in that driving shaft (2) can do, down, a left side, the adjusting of right four direction, on the driving shaft (2), the adjusting of following both direction is to adopt screwed eccentric bearing block (5), rotating eccentricity bearing support (5) has utilized the eccentric position different adjustment upper-lower position of driving shaft (2), driving shaft (a 2) left side, the adjusting of right both direction is to adopt screwed bearing inner seat (9), in the swivel bearing seat can regulate driving shaft (2) about two directions.The adjusting of former and later two directions of driven shaft (18) is to adopt screwed bearing inner seat (30), and seat (30) can be regulated the fore-and-aft direction of driven shaft (18) in the swivel bearing.Like this, worm-cam (3) and the roller-dear (4) on the driven shaft (18) on the driving shaft (2) can pass through driving shaft, and the six direction of driven shaft is regulated the cooperation that improves, and reaches required precision.After the same driven shaft of driving shaft (2) (18) levelling, the available porous location piece of driving shaft (2) (10), bearing cap (11), screw (15) positioning and fixing, the available porous location piece of driven shaft (18) (19), bearing cap (20), screw (23) positioning and fixing.Pore size on the porous location piece and arrangement position award definite according to the required precision of regulating.The location is simple, convenient disassembly.Above-mentioned same structure can be applied to worm and wheel, the driving mechanism of gear and gear pattern.
Driving shaft of the present utility model has adjustable performance with driven shaft, therefore the utlity model has following advantage:
The first, make simple, easy standardization, seriation.Machining accuracy to other part can reduce, and can guarantee matching requirements.
The second, debug convenient and simple.Driving mechanism has produced wearing and tearing after turning round through certain hour, makes the cooperation between roller-dear, the worm-cam not reach requirement, at this moment can pass through driving shaft, and the mutual adjusting of the six direction of driven shaft diaxon reaches the cooperation requirement.The driving mechanism that does not have adjusting function, quality of fit require will be difficult to reach.
The 3rd, precision height, length direction (about, front and back) degree of regulation can reach 0.05mm, and centre distance also can guarantee in the 0.05mm scope.
The 4th, oil seal replacement is simple, does not need to readjust main, preceding axle position after the replacing.
Below in conjunction with embodiment accompanying drawing is done an explanation.
Accompanying drawing 1 is the structure front view of worm-cam driving mechanism.
Accompanying drawing 2 is the structure side view of worm-cam driving mechanism.
Accompanying drawing 3 is worm-cam driving mechanism driving shaft eccentric adjustment and axial adjustment figure
Embodiment 1
The below of casing among the figure (1) casing is driving shaft (2), driving shaft (2) one ends are equipped with bearing (13), and be installed on the screwed bearing inner seat (9), bearing inner seat (9) is installed on the screwed eccentric bearing block (5), fill out oil sealing (14), O RunddichtringO (16), (17).During the threaded eccentric bearing block of rotating band (5), regulated eccentric central position, the position of driving shaft (2) can upper and lowerly be regulated, by set screw (12) eccentric bearing block (5) is fixed on the casing, the threaded bearing inner seat of rotating band (9) can make driving shaft (2) make left and right adjusting, with the screw eyelet in the seat (9) in the eyelet alignment bearings in the porous location piece (10), cover bearing cap (11), use screw (15) that bearing inner seat (9) is fixed its position then.The other end at driving shaft (2) is same structure equally.Casing top driven shaft (18) one ends are loaded onto bearing (27) and are refilled axle ring washer (25), and be installed on the screwed bearing inner seat (30), bearing briquetting (26) compresses bearing (27) and is installed on the bearing outer seat (29), fill out O RunddichtringO (20), (21), oil sealing (24).Rotate threaded bearing inner seat (30) or so that driven shaft (18) is done the adjusting of forward and backward two directions.Go up screw eyelet boss with the eyelet alignment bearings briquetting (26) in the porous location piece (19) and be embedded in the groove of bearing outer seat (29) bearing inner seat (30), cover bearing cap (20), use screw (23) that bearing inner seat (30) is fixed its position then.By the adjusting of above-mentioned six direction, make the worm-cam (3) that is contained on the driving shaft (2) reach required precision with the cooperation that is contained in roller-dear on the driven shaft (4).
Embodiment 2
With implementing 1 difference is that worm-cam (3) on the driving shaft (2) changes gear into; Roller-dear on the driven shaft (4) changes gear into.
Embodiment 3
Difference from Example 1 is that the worm-cam (3) on the driving shaft (2) changes worm screw into; Roller-dear on the driven shaft (4) changes worm gear into.
