Abstract
The utility model discloses a planet steel-ball step-less speed changer, which is a mechanical transmission device which can change the speed by the rubbing effects of the steel ball which makes the planetary motion. A transmission ratio is made to smoothly fluctuate within the ranges of i=3 to omega by changing the way of distribution circle diameters of the steel ball. Since the utility model has the functions of deceleration, zero output, and constant power transmission, and sometimes, the planet steel-ball step-less speed changer performs the function of being integrated with a clutch, a speed changer, and a speed reducer. The utility model is widely suitable for industrial departments, such as light textiles, chemical industry, packaged food products, machine tools, instruments, etc. Because of the characteristics, if the utility model is matched with an appropriate differential device, the utility model can also realize the step-less regulation of the output rotary speed of constant-speed and large-power machines.
Description
The utility model relate to a kind of by doing planetary motion steel ball and the rubbing action of other elements, and can change the mechanical variable-speed unit of output speed smoothly through manipulation.Belong to the mechanical transmission category.
With the similar existing machinery stepless speed changes devices of the utility model the KOPP-B type is arranged, the COntraves type and the patent No. are " inner cone steel ball type " stepless speed variator and BUS type and the SC type planetary stageless speed variator of F16H49/OOCN85200829U.
KOPP-B type wherein, COntraves type and " inner cone steel ball type " stepless speed variator all with steel ball as the speed change transmission component, and steel ball all rotates in fixed axis.By changing the tilt angle and the direction speed change of steel ball rotating shaft.Wherein the steel ball of KOPP-B type and " inner cone steel ball type " speed changer all has a hole.And in adorn little axle, the gear range of above-mentioned three kinds of speed changers is about i=1/ (2,9)～3.5.
The speed change transmission component of BUS type and SC type speed changer is done planetary motion, but is not steel ball but circular cone assemblying body.Its geometric element and precision key element are all more by contrast, and the manufacturing process complexity reaches usage requirement, must pay higher technology cost.Realize speed change by the mode that moves axially static outer shroud.Gear range i=3～115.
In above-mentioned several existing apparatus, with the contacted transmission component of middle rolling element (steel ball or circular cone assemblying body), its contact position is relatively-stationary, and this early fatigue that causes the part, contact position easily damages, thereby influences working life.
The purpose of this utility model is to provide a kind of mechanical stepless speed-changing transmission device, and it can be in the scope of 3～∞, and continuously smooth ground changes transmission speed ratio.And in needed any section, has constant power output characteristic.
The purpose of this utility model is achieved in that it is middle rolling element with several simple steel balls, when it does planetary motion, to be positioned at the rotatablely moving of active member of central authorities, pass to driving link coaxial and be positioned at the drive element of an end by certain speed ratio relation.Change transmission speed ratio by the distribution circle diameter that changes steel ball.
The best way of concrete structure of the present utility model and realization is provided by accompanying drawing.
Mutual opposed upper cone (6) and lower cone (7) are formed active member.It is with coaxial and between the mutual involutory quiet dish (3) and Moving plate (4), uniform the planetary steel ball (2) that several contact simultaneously with above-mentioned each element.Input shaft (1) is connected with upper cone (6) and closes with the key cunning with lower cone (7), and output shaft (5) is connected with Moving plate (4).
With rotation speed n
1, the input shaft of rotation (1) drives upper/lower cone (6), rotate (7); Two cones drive steel ball (2) by rubbing action and do the planetary motion that existing revolution has rotation again along the circumference of quiet dish (3).Because the Moving plate (4) that contacts with steel ball (2) and the contact circular diameter Dt of quiet dish (3) and the size of Df have difference △=Df a---Dt, thereby make Moving plate (4) with certain rotation speed n
2Rotate, and export by output shaft (5).When by the axial distance between Effector change upper/lower cone (6), (7), also force steel ball (2) to change the size of its distribution circle diameter DM, thereby change the size that contacts circular diameter Dt and Df of steel ball (2) and Moving plate (4) and quiet dish (3).Because Moving plate (4) and quiet dish (3) are respectively interior surface of revolution and internal conical surface with the contact surface of steel ball (2), therefore the size variation that contacts circular diameter Dt and Df is also unequal, be that difference △ is not constant, and cause the rotation speed n of Moving plate (4) by the variation of △
2Change, thereby realize the stepless change transmission.
The utility model is compared with above-mentioned existing similar device and is had the following advantages:
1, gear range broadness, i=3～∞, namely working as input speed is n1The time, output speed is n2＝0～ 1/3 n
1 Because the drive characteristic of reduction of speed and zero output is arranged, where necessary, can bring into play the collection clutch, the effect of speed changer and decelerator.
2, the position that contacts with each other of each transmission component changes with the change of velocity ratio.Therefore can avoid the early fatigue of part, contact position to damage, increase the service life, so brought into play the bearing capacity of material fully.
3, middle rolling element is simple spheroid, is about to the use of directly packing into of qualified steel ball, need not reprocess out any other structure, so structural Case is simple outward.
Claims (2)
1, a kind of mechanical stepless speed-changing device, by input shaft (1) steel ball (2), quiet dish (3), Moving plate (4), output shaft (5).Upper cone (6) and lower cone primary components such as (7) constitute.It is characterized in that opposed upper cone (6) and lower cone (7) can relatively move, be distributed in they and quiet dish (3) and make, the steel ball (2) as planetary component between the Moving plate (4) changes its distribution circle diameter.
2, device according to claim 1 is characterized in that used steel ball (2) for processing the simple spheroid of any other structure, has one to have internal conical surface among quiet dish (3) and the Moving plate (4), and another has interior surface of revolution.
