Abstract
The present invention relates to a mechanical driving device, more specifically, a speed difference reducer using the speed difference of nonuniform speed motion to complete force transmission and having large transmission ratio. The speed difference reducer is provided with a driving shaft (1), a driven shaft (4), a first driving cone tooth (2) and a second driving cone tooth (3), wherein the driving shaft (1) is perpendicular to the driven shaft (4), and a large double-cone tooth slide gear (5) and a small double-cone tooth slide gear (6) are sheathed on the driven shaft (4) in a sliding mode; a planetary gear (7) is arranged between the large double-cone tooth slide gear (5) and an inner annular gear (9) of the small double-cone tooth slide gear, and the planetary gear (7) is simultaneously meshed with the annular gears (9) at both sides; a wheel rib (8) of the planetary gear (7) is in transmission connection with the driven shaft (4). Because the two double-cone tooth slide gears generate speed difference because of different diameters, the planetary gear (7) is simultaneously controlled by the opposite driving force and the speed difference balance driving force of the two double-cone tooth slide gears. The desired transmission ratio can be obtained through adjusting the diameter difference of the two double-cone tooth slide gears, and the transmission ratio can reach thousands to ten of thousands. In addition, the speed difference reducer has the advantage of very simple and compact structure, and thus, volume is smaller relatively.
Description
Technical field
The present invention relates to a kind of mechanical transmission, specifically finish the transmission of power, and have the differential speed reducer of big speed ratio with the speed difference of non-movement at the uniform velocity.
Background technique
Speed reducer is mechanically operated important composition part, and application area relates to the every field and all trades and professions of national economic development.In the world and domestic, all dynamic power machine transmission devices just develop along miniaturization, speed up, low noise, high reliability direction, and speed reducer then develops towards miniaturization, big speed ratio (thousands of to tens thousand of) direction.And traditional speed reducer such as planetary speed reducer, cycloidal planetary gear speed reducer and harmonic wave speed reducing machine etc., owing to be subjected to the restriction of its deceleration principle, as obtaining big speed ratio, especially high-power big speed ratio, whole volume is very big, cause the speed reducer strange phenomenon also bigger than prime mover, as disclosed on January 1st, 1992, publication number is disclosed high-power among the CN1057511A, the big variation, high efficiency light-duty formula speed reducer, this not only causes manpower, material resources, financial resources are wasted greatly, also seriously affect the developing steps of China's industrial and agricultural machineryization and the progress of science and technology simultaneously.
Summary of the invention
The objective of the invention is to provides a kind of velocity ratio height, speed reducer that volume is little for overcoming the deficiencies in the prior art.
For achieving the above object, the technology used in the present invention solution is as follows: differential speed reducer, comprise mutual vertically disposed driving shaft and driven shaft, it is characterized in that: one in front and one in back be fixed with the 1st bigger initiative taper tooth of diameter and the 2nd less initiative taper tooth of diameter on the described driving shaft, flip sleeve is provided with different big bipyramid tooth sliding gear of flank of tooth relative diameter and little bipyramid tooth sliding gear on the described driven shaft, be equipped with external toothing and ring gear on big bipyramid tooth sliding gear and the little bipyramid tooth sliding gear, described big bipyramid tooth sliding gear is identical with ring gear diameter on the little bipyramid tooth sliding gear, described big bipyramid tooth sliding gear and little bipyramid tooth sliding gear are in the driving shaft both sides respectively, the external toothing of described big bipyramid tooth sliding gear and the engagement of the 1st initiative taper tooth, the external toothing of described little bipyramid tooth sliding gear and the engagement of the 2nd initiative taper tooth, be provided with planetary pinion between the ring gear that big bipyramid tooth sliding gear and little bipyramid tooth slide and mesh with the both sides ring gear simultaneously, described planetary pinion spoke and driven shaft are in transmission connection.
Differential speed reducer is with two driving gears of prime mover connecting shaft, two the bipyramid tooth sliding gears of tending to act respectively, the inner cone tooth while of two bipyramid tooth sliding gears meshes with the planetary pinion on the planetary pinion spoke, because two bipyramid tooth sliding gears produce speed difference because of Different Diameter, thereby planetary pinion is subjected to the effect of two incorgruous driving forces of bipyramid tooth sliding gear and speed difference balance driving force, generation displacement in rotation simultaneously.Because planetary pinion spoke key connects output shaft, so planetary displacement amount is exactly the commentaries on classics degree of output shaft, big speed ratio is more little more for the speed difference, close steps is big more more for the speed difference, poor by the diameter of regulating two bipyramid tooth sliding gears, just can obtain required velocity ratio, velocity ratio can reach thousands of to tens thousand of.The structure of differential speed reducer is very succinct, compact in addition, and therefore, volume is less relatively.
The invention will be further described below in conjunction with the drawings and specific embodiments.
