Abstract
A differential speed reducer using speed difference to transfer force to obtain big drive ratio is composed of the mutually perpendicular drive axle and driven axle, the first and second drive bevel gears, the big and small gears with dual-conic teeth and sliding on driven axle, and a planetary gear between the internal toothed rings of said big and small gears and engaged with them. Regulating the difference between the diameters of said big and small gears can obtain needed drive ratio up to thousands or ten thousands.
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, causes the speed reducer strange phenomenon also bigger than prime mover, this not only causes human and material resources, financial resources to waste greatly, also seriously affects 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, it is characterized in that: described differential speed reducer is provided with mutual vertically disposed driving shaft and driven shaft, 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
