Abstract
The invention discloses a stepless gearbox. The stepless gearbox comprises a box body, an input shaft and an output shaft. Both the input shaft and the output shaft are provided with conical gears, and the two conical gears are identical in gear shape and are arranged in opposite directions; the input shaft is slidingly connected with the box body, and the output shaft is mounted onto the box body through two fixing holes; the diameter of the fixing holes is larger than that of the output shaft, a bearing is arranged inside the fixing holes, and springs are arranged between the bearing and the fixing holes. According to the stepless gearbox, the input shaft is slidingly connected with the box body, and the input shaft is connected with one conical gear, the input shaft can move left and right; the output shaft is connected to the box body in a floating mode, and the output shaft is connected with one conical gear in the opposite direction; when the input shaft moves, the engagement position of the conical gear on the input shaft and the conical gear on the output shaft can be changed, and due to the fact that the linear speeds of every axial position of the conical gears are different, stepless gearshift can be achieved.
Description
Technical field
The invention belongs to the technical field of transmission.
Background technique
Gearbox is to produce variable-speed torque-converting by different Gear combination, the gear that conventionally needs output shaft respectively with input shaft on a plurality of gears engagements reach speed change.But adopt the mode of a plurality of driving gears, exist following drawback: 1, the velocity ratio of every pair of gear is fixed, therefore the rotating speed of output is also fixed, can not realize velocity ratio arbitrarily; 2, on input shaft, need a plurality of gears are installed, increased the difficulty of installing.
Summary of the invention
The invention provides a kind of infinitely variable transmission, to solve the problem that needs a plurality of driving gears to realize speed change.
In order to solve the problems of the technologies described above, the invention provides following technological scheme: a kind of infinitely variable transmission, comprise casing, input shaft and output shaft, bevel gear is all installed on input shaft and output shaft, and the profile of tooth of two bevel gears is identical and oppositely arrange, and input shaft is connected with box body-sliding, output shaft is arranged on casing by two fixed holes, the diameter of fixed hole is greater than the diameter of output shaft, is provided with bearing in fixed hole, between bearing and fixed hole, is provided with spring.
In the present invention, two bevel gears oppositely arrange, and mean the bottom surface of a bevel gear and the summit of another bevel gear is positioned at same one end.
Compared with prior art, the invention has the advantages that: input shaft is connected with box body-sliding, on input shaft, be connected with bevel gear, input shaft can move left and right, and output shaft floating connection is on casing, and on input shaft, Opposite direction connection has bevel gear, when mobile input shaft, therefore the bevel gear engaging position of the bevel gear on input shaft and output shaft can change, because the linear velocity of the axial everywhere of bevel gear is different, therefore can realize stepless change.
Because output shaft floating connection is on casing, can be according to the movement of input shaft adjusted position voluntarily.
Further, on described bevel gear, have lightening hole, can alleviate the weight of part in the present invention program.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, technical solution of the present invention is further illustrated:
Fig. 1 is infinitely variable transmission embodiment's of the present invention structural representation.
Embodiment
Reference character in Figure of description comprises: casing 1, input shaft 2, output shaft 3, bevel gear 4, angular-rate sensor 5, fixed hole 6, spring 7.
As shown in Figure 1, a kind of infinitely variable transmission in the present embodiment, comprises casing 1, input shaft 2 and output shaft 3, on input shaft 2 and output shaft 3, bevel gear 4 is all installed, the profile of tooth of two bevel gears 4 is identical and oppositely arrange, and on bevel gear 4, has lightening hole.Input shaft 2 is slidably connected with casing 1, output shaft 3 is provided with angular-rate sensor 5, output shaft 3 is arranged on casing 1 by two fixed holes 6, the diameter of fixed hole 6 is greater than the diameter of output shaft 3, in fixed hole 6, be provided with bearing, between bearing and fixed hole 6, be provided with spring 7, output shaft 3 can fluctuate in fixed hole 6.
Input shaft 2 moves right, and the bevel gear 4 on input shaft 2 also moves right, and the contact points of two angular wheels 4 also changes, and output shaft 3, in the drive of input shaft 2 bevel gears 4, upwards floats, and realizes deceleration.Input shaft 2 is to left movement, and the bevel gear 4 on input shaft 2 is also to left movement, and the contact points of two angular wheels 4 also changes, and output shaft 3, in the drive of input shaft 2 bevel gears 4, upwards floats, and realizes speedup.
Output shaft 3 is provided with angular-rate sensor 5, can reflect in real time the angular velocity varies of output shaft 3.
For a person skilled in the art, not departing under the prerequisite of structure of the present invention, can also make some distortion and improvement, these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
Claims (2)
