Abstract
The utility model provides a double-axle speed changing machine, which is composed of a driving axle, a driven axle and driving gears of different proportional dimension installed on the two axles, wherein, an inner sleeve wheel and outer sleeve wheels of different dimension are sheathed on the driving axle. Helical gear teeth arranged on the inner sleeve wheel are engaged with helical gear teeth of each outer sleeve wheel, and the inner sleeve wheel does equal speed movement with the outer sleeve wheels together; a push operating rod pushes a braking pin through a connecting rod, making the inner sleeve wheel slide out to be engaged with engaging teeth fixed on the driven axle, and the utility model is put into gear; the driven axle is driven to make low speed or intermediate speed or high speed reversing rotating, realizing the purpose of speed changing. The utility model has the advantaged of simple structure and easy use, and can directly be put into a gear and carry out speed changing without the help of a clutch.
Description
The utility model belongs to a kind of twin axle variable-speed motor, specifically a kind of machinery that is used for conversion rotating speed and motion speed.
Present normally used governor mainly contains two classes, and a class is rotating speed or the motion speed that how much increases or reduce machinery with power consumption, and another kind is to carry out speed governing such as speed-adjustable motor by the magnetic force size, and the common drawback of above-mentioned two kinds of governors is can not change of load.Have a kind ofly to be the many wheel shafts of multi-gear and to come the governor of speed governing by means of clutch shift, its shortcoming is that member is many again, complex structure, and troublesome poeration, the at first left alone without help car of the clutch gearshift of putting into gear again, and also this governor can not carry out speed governing in that fixed equipment is in service.
It is a kind of simple in structure that the utility model provides, and need not by the clutch speed change of can directly putting into gear, and can carry out the twin axle variable-speed motor of Emergency braking braking.
The utility model is by driving shaft and driven shaft and the purpose that reaches speed change by the driving gear that is installed in different proportion size on two axles, wherein be fixed with small gear on the driving shaft, middle gear, gearwheel and reverse small gear, wheel and outer wheel in being with on the driven shaft, outer wheel comprises the driven shaft gearwheel, the driven shaft middle gear, the driven shaft small gear, reverse little tooth, the idle pulley that connects the reverse gear of reverse small gear of driving shaft and driven shaft, there are the spirality gear teeth to be meshed on the interior wheel with the spirality gear teeth of outer wheel, do to rotate with outer wheel with speed, have engaging tooth to be fixed on the driven shaft between wheel in each, fixing shelves cover arranged between reverse gear and driven shaft small gear, this fixedly interstage sleeve be fixed on the driven shaft, the laterally movable shotpin of wheel is connected with connecting rod in the restriction, and connecting rod is connected with operating handle; The pulling operating handle, by connecting rod stir or the band brake pin make in wheel skid off and promptly hang up retaining with the engaging tooth engagement that is fixed on the driven shaft, drive driven crop rotation low speed or middling speed, at a high speed, backward rotation, realize changed speed operation.
The utlity model has simple in structure, easy to operate, do not need by clutch, the speed change of can directly putting into gear adapts to the needs of various load variations and operation.

Further specify the utility model embodiment below in conjunction with accompanying drawing.
The twin axle variable-speed motor is made of driving shaft 1 and driven shaft 18 and the driving gear that is installed in two different proportion sizes on the axle, on driving shaft 1, be fixed with small gear 2, middle gear 3, gearwheel 4, reverse small gear 5, in on driven shaft 18, being with wheel 20 and outside wheel, outer wheel comprises driven shaft gearwheel 10, idle pulley 6 connects reverse small gear 5 of driving shaft and driven shaft reverse gear 10, there are the spirality gear teeth 22 to be meshed on the interior wheel 18 and rotate with speed with outer wheel with the spirality gear teeth of outer wheel, between the wheel engaging tooth 19 is arranged on the driven shaft 18 each, 21 engaging tooths are with screw or sell 23 and be fixed on the driven shaft 18, between reverse gear 10 and driven shaft small gear 12, there is fixing shelves cover 11 to be fixed on the driven shaft 18, the laterally movable shotpin 8 of wheel in the restriction, 13,15,17 are connected with connecting rod 9, connecting rod 9 is connected with operating handle 7 and promotes or pulling operating handle 7 is stirred shotpin 17 or 15 by connecting rod 9,13,8, wheel 20 skids off in making, with be fixed on engaging tooth 19 on the driven shaft 18,21 engagements, thereby drive driven shaft 18 and make low speed or middling speed, at a high speed, backward rotation realizes changed speed operation.
Operating principle of the present utility model, when making low-speed running, promote operating handle 7 and stir shotpin 17 by connecting rod 9, make in wheel skid off be fixed on driven shaft 18 on engaging tooth 19 be meshed, at this moment the 5 drive driven shaft gearwheels 16 of the small gear on the driving shaft are done to slowly run, when doing the middling speed running, then spur operating handle 7, stir shotpin 15 by connecting rod 9, make driven shaft middle gear 14 from interior wheel 20 skid off be fixed on driven shaft on engaging tooth be meshed, at this moment the middle gear on the driving shaft 3 drives driven shaft middle gears 14 and makes middling speed and rotate.At this moment, from cutting interior wheel 20 automatic homings of a gearwheel 16, break away from engagement; The operating principle that runs up is the same.When reversing, pulling operating handle 7, drive shotpin 8 by connecting rod 9, the interior wheel of reverse gear 10 is skidded off, be meshed with the engaging tooth on being fixed on driven shaft, at this moment the reverse small gear 5 on the driving shaft drives driven shaft reverse gear 10 by idle pulley 6 and makes backward rotation, and wheel playback in shotpin 13,15,17 controls breaks away from engagement idle running.
