Specific embodiment
As shown in Figures 1 and 2, the utility model provides a kind of gearbox, including:
The input shaft being connected with drive device, is fixedly connected with output gear 1 on output shaft;
The output shaft being connected with rotary part, is fixedly connected with input gear I 14 and input gear II 3 on input shaft;
Jackshaft 12, is fixedly connected with the change-speed gearing I 4, speed change different with diameter of intermediate drive gear 2 on jackshaft 12 Gear II 5, intermediate drive gear 2 is connected with the engagement of output gear 1;Jackshaft 12 can be by flat key and intermediate drive gear 12 Connection;Change-speed gearing I 4 and change-speed gearing II 5 are arranged between input gear I 14, input gear II 3.Input gear I 14 with it is defeated The diameter for entering gear II 3 is identical, or has different diameters from change-speed gearing I 4 and change-speed gearing II 5.
With change-speed gearing I 4 and the common pushing meanss being connected of change-speed gearing II 5, pushing meanss are by promoting change-speed gearing I 4 and the axial movement of different directions of the change-speed gearing II 5 on jackshaft 12, formed with input gear I 14 and input gear II 3 Three kinds of one kind of annexation, reach different movement effects below:
(A):Axially movable, when change-speed gearing I 4 is connected with the engagement of input gear II 3, exported by drive device Power passes sequentially through input gear II 3, change-speed gearing I 4, intermediate drive gear 2, output gear 1 and passes to rotary part, is formed A kind of motion of speed;
(B):Along with(A)The axial direction operation of opposite direction, when change-speed gearing II 5 is connected with the engagement of input gear I 14, passes through The power of drive device passes sequentially through input gear I 14, change-speed gearing II 5, intermediate drive gear 2, output gear 1 and passes to rotation Rotation member;Because the diameter of change-speed gearing I 4, change-speed gearing II 5 is different, cause to pass to rotary part by input gear I 14 Rotating speed it is different, reach the purpose of variable motion;
(C):Change-speed gearing I 4, change-speed gearing II 5 are not connected with input gear I 14 and input gear II 3.Now, speed change Gear I 4 and change-speed gearing II 5 are located between input gear I 14 and input gear II 3, are not contacted with either of which, realize every From the purpose of motion.
The utility model also includes swingle 9, and swingle 9 is connected with pushing meanss, is pushed away by rotarily driving for swingle 9 Dynamic device motion, and then drive change-speed gearing I 4 and change-speed gearing II 5 to be axially moved along jackshaft 12.
Pushing meanss include sliding block 11 and support guide axle 10, and sliding block 11 is moved on support guide axle 10, support guide Three deep-slotted chip breakers are provided with axle 10, sliding block carries out three positions to sliding block by the spring barrel 13 being engaged with deep-slotted chip breaker The positioning put.Spring barrel 13 is fixedly installed, when deep-slotted chip breaker slides into the position of spring barrel, by springlock Determine device to be fixed change-speed gearing with the cooperation of deep-slotted chip breaker.Three positions correspond to change-speed gearing I 4 and input gear II respectively The position of 3 engagement connections, change-speed gearing II 5 engage position, change-speed gearing I 4, the change-speed gearing II 5 being connected with input gear I 14 The position not being connected with input gear I 14 and input gear II 3, realizes that two kinds of different speed changes and isolation are moved.
Chute 16 is provided with sliding block 11, the adapting rod I 15 vertical with swingle 9, adapting rod I 15 are set on swingle 9 Upper connected adapting rod II, swingle 9 by driving slip of the adapting rod II in chute 16, with movable slider 11 along jackshaft 12 It is axially moved.
In above-mentioned structure of the present utility model, geared parts can be arranged on all of by casing I 7, casing II 8, lead to In the casing that lid 6 is formed, wherein, output shaft, input shaft, swingle are stretched out outside casing, are easy to and outside rotary part, driving Device, slewing connection.
In device of the present utility model, input shaft and output shaft are arranged in the same horizontal line, and jackshaft one end is spline Axle, the other end is connected using flat key with intermediate drive gear 2, and two change-speed gearings are connected by sliding block 11 on jackshaft 12 Connect, being synchronized with the movement when realizing speed change, can reduce jackshaft makes structure become simple.Two change-speed gearings can depart from simultaneously to be nibbled Close, so as to realize the same occasion for driving the multiple motions of driving simultaneously to need a certain mechanism's stop motion, substantially increase The function of gearbox.Same jackshaft realizes three kinds of different motion conditions simultaneously, substantially reduces the volume of gearbox, is real The modern mechanical of existing high-precision provides a kind of new speed change gear.
During utility model works, drive device and input shaft are connected, and drive input shaft to drive input gear I and input tooth Wheel II is rotated together, and input gear I and input gear II are engaged with change-speed gearing respectively, realizes carrying out rotating speed while transmission Change, then output gear 1 is transmitted motion to by intermediate drive gear 2, output gear 1 and output shaft are rotated and driven together Motion is operated.In the process of running, rotate swingle 9 to be slided on support guide axle 10 with movable slider 11, and prop up The deep-slotted chip breaker set on the support axis of guide, is sliding into speed change when certain position engages gear by spring barrel The position of gear is fixed, so that more stable carrying out is driven.
Above-described is only preferred embodiment of the present utility model, it is noted that for those skilled in the art For, under the premise of the utility model general idea is not departed from, some changes and improvements can also be made, these should also be considered as Protection domain of the present utility model.
