Abstract
The utility model discloses a stepless gear with auto-adjusting pressure, planet differential, and zero starting functions, which comprises two parts of a differential speed regulation structure composed of a conical planet wheel, an input friction disc, an output friction disc and a regulating ring, and an auto-adjusting pressure structure composed of a pressure adjusting cam and a pressure adjusting steel ball; when the regulating ring is contacted with the edge of the planet wheel, the rotation speed of the output shaft is reduced to zero; when the regulating ring is contacted with the conic node of the planet wheel, the rotation speed of the output shaft is increased close to the rotation speed of the input shaft; when the load is increased, the output torque is enhanced by the automatic pushing and pressing friction disc of the auto-adjusting pressure structure, and constant power is exported; when the load is small, the friction pressure is automatically reduced by the auto-adjusting pressure structure for reducing unnecessary grinding; the utility model is suitable for various devices required stepless gear, in particular to the equipment required no starting impact and the transport machinery of middle and small horse power.
Description
The utility model belongs to planetary friction stepless gearbox, relates to machine building industry.
Existing multiple stepless speed variator from price performance, be best, simple in structure, easy to maintenance with the belt continuously variable transmission, but it is narrow to have speed adjustable range, and low speed is non-vanishing, and starting-impact is arranged, and volume is big, the deficiency that permanent power range is narrow.Chinese patent application numbers 87207067 provides a kind of differential roller stepless speed variator, its advantage is to have solved permanent power zero-bit on a large scale to start infinite variable speed problem, but deficiency is to use hyperbola bevel gear and drum-shaped roller, need special device, when secondly input shaft is reverse, output characteristics differs greatly (oppositely time, planet wheel does not have friction pressure).
The purpose of this utility model is: a kind of part is provided, and complete machine structure is simple, high-power output, and low speed is zero, at a high speed near input shaft rotating speed (about more than 2/3, show that design parameter is different and decide), the stepless speed variator that permanent on a large scale power is exported.
The utility model is because of adopting planetary structure of friction wheel, and zerol bevel gear is processed, so need not special device, the automatic Regulation structure makes the stepless speed variator function not be subjected to the influence of input redirect in addition.
Concrete structure of the present utility model and working principle are provided by following examples and a pair figure:
Fig. 1----transmission principle figure
Fig. 2----stepless speed variator plan view
Fig. 3----stepless speed variator left view
A kind of automatic Regulation planetary differential zero-bit starting stepless speed variator is by input shaft, the input friction disk, and planet wheel, retainer, speed ring, the output friction disk, automatic Regulation cam A, B, the pressure regulation steel ball, loaded spring, output shaft is formed.As shown in Figure 2, power reaches input friction disk (71) by input shaft (77) with moment of torsion and makes planet wheel (2) rotation, planet wheel (2) is with the friction pressure of its conical surface to speed ring (3), internal surface revolution and rotation along speed ring (3), according to force balance principle, exert pressure to output friction disk (17) in planet wheel (2) bottom, because of the rotation and the revolution of planet wheel (2) make (17) thus rotation by automatic Regulation cam A(17), B(15), pressure regulation steel ball (16), make output shaft (13) output, because the adjustable positions of speed ring (3), so when input shaft (77) constant speed was rotated, planet wheel (2) had different rotations and revolution speed, make output friction disk (17) have different rotating speeds to reach output shaft (13).Automatic Regulation cam A(17A), when B(15) making output shaft (13) unloaded with the structure of pressure regulation steel ball (16) and loaded spring (19), pressure regulation steel ball (16) falls into automatic Regulation cam A(17A just), the lowest point B(15), the suffered friction pressure minimum of planet wheel (2) this moment; When output shaft (13) is loaded, automatic Regulation cam A(17A), B(15) produce phase difference, its inclined-plane extruding steel ball (16), to export friction disk (17) and press to input friction disk (71), because of the direction of displacement of the bottom of planet wheel (2) and output friction disk (17) has an angle, and the bottom of planet wheel (2) is transfused to friction disk (71) again and props up, so planet wheel (2) outwards pushes speed ring (3), so planet wheel (2) becomes big to the friction pressure of speed ring (3), at this moment, the friction pressure of each fastness all increases, and makes the output torque of output shaft become big; Speed ring (3) is shifted to output shaft one side, and the point of contact that the point of contact of planet wheel (2) and speed ring (3) surpasses planet wheel (2) and output friction disk (17) at axial position is during in axial position, and output shaft (13) rotating speed is zero.
As shown in Figure 2: an end of output shaft (13) has spline, and the other end has the keyway of flat key; Output friction disk (17) all is curved rubbing surfaces with the circumference of input friction disk (71), and there is circular hole at part (13) middle part, and (17) one side is the light face, and another side is the inclined-plane (17A) of compression relief cam; Automatic Regulation cam B(15) be an axle sleeve class part, the middle part is an internal spline, and an end is the inclined-plane of compression relief cam; Input shaft is an axle sleeve class part, endoporus has a keyway to be connected with motor reel with key, cylindrical uses bearing fixing on body (7), interior circle is fixed on the right-hand member of output shaft (13) with thrust bearing and radial bearing, the right-hand member of output shaft (13) has screw thread, but with each fastness of nut preset the friction pressure when unloaded.Planet wheel (2) is the cone piece that is umbrella, its umbrella handle portion retainer (18) of packing into, and the left end that the internal surface right side of retainer (18) is enclosed within input friction disk (71) is fixed.The circle center hole of output friction disk (17) is enclosed within on the output shaft (13).Automatic Regulation cam A(17A), the nest (can show that watt level is designed to 4,6,8,12) of 6 assembly pressure regulation steel balls (16) is respectively arranged on B(15), whole surface is wavy.Automatic Regulation cam A(17A), stud with a loaded spring (19) that is enclosed within on the output shaft (13) between B(15).The internal surface of speed ring (3) takes the shape of the letter U, direction at the shaft axis that is parallel to output shaft (13) has a hole (21), bolt passes hole (21) speed ring (3) is fixed on the tooth bar (25), worm gear and gear are connected, when shaking speed-regulating handle (worm screw 28), the gear driven tooth bar makes speed ring move the realization speed governing (prior art).
