Description
The utility model belongs to mechanical transmission, specifically a kind of three-phase side-by-side connecting rod formula impulse stepless gear box.
The three-phase side-by-side connecting rod formula impulse stepless gear box that generally adopts ［ is seen the 482nd～484 page of " mechanical stepless transmission " (China Machine Press publish October nineteen eighty-three) ］ at present, output angle velocity fluctuation amount is bigger in the course of the work, efficient is lower, speed adjustable range is less, influences the complete machine performance and can only horizontally use.
The utility model has been done improvement to the structure of former three-phase side-by-side connecting rod formula impulse stepless gear box, provides output angle velocity fluctuation amount little, efficient height, the horizontal and vertical three-phase side-by-side connecting rod formula impulse stepless gear box that speed adjustable range is big.
Horizontal three-phase side-by-side connecting rod formula impulse stepless gear box is characterised in that, input bent axle and the changeable length connecting rod direct connection that constitutes by connecting rod head and sleeve, and make the gyration center of speed governing block bearing and import the gyration center of bent axle and the gyration center conllinear (being the three-core conllinear) of output shaft, directly machining worm (is the last screw rod that is divided into of same bar on speed adjustment screw, another part is a worm screw) mesh with worm gear, the surface of contact of inner yoke and roller is the curved surface of the constant angle of wedge.
Vertical three-phase side-by-side connecting rod formula impulse stepless gear box is characterised in that, input bent axle and the changeable length connecting rod direct connection that constitutes by connecting rod head and sleeve, and make the gyration center of speed governing block bearing and import the gyration center of bent axle and the gyration center conllinear (being the three-core conllinear) of output shaft, directly machining worm (is the last screw rod that is divided into of same bar on speed adjustment screw, another part is a worm screw) mesh with worm gear, the surface of contact of inner yoke and roller is the curved surface of the constant angle of wedge, and the input bent axle is provided with the cam that drives lubricant pump.
Compared with the prior art the utility model has the following advantages:
Free wheel device rotates output continuously with the pulsation that the swing of outer yoke circle changes into output shaft, regulates the horizontal position of speed governing frame and speed governing block bearing by speed adjustment screw, and the dimension scale that changes main drive gear has realized stepless change;
Adopt input bent axle and changeable length connecting rod direct connection, eliminated known technology, make the shortcoming of overall efficiency reduction, improved overall efficiency and simplify the structure, enlarged speed adjustable range because of connecting rod is that offset distance swing guide pin bushing runs up down at the input bent axle that inertial force increases;
Adopt the three-core conllinear, both improved processability of product structure, make the angular velocity curve symmetry of output shaft again, reduced the angular velocity pulsating quantity of speed changer, improved kinetic characteristic;
Worm screw position at speed adjustment screw is equipped with the size that worm gear shows output speed, has simplified the known technology medium speed and has shown that needed pressing plate, speed governing spiral shell piece, shift fork, little axle, pointer etc. than complex mechanism, have reduced cost;
The surface of contact of inner yoke and roller is the curved surface of the constant angle of wedge, make between each roller load distribution even, overcome known technology culminant star wheel surface and adopted the plane, the angle of wedge changes thereupon when roller wearing and tearing or the change of working surface contact position, cause that each roller carries uneven shortcoming, improve bearing capacity, prolonged the working life of speed changer.
Except that having above-mentioned advantage, also has advantage of simple structure for vertical speed changer.Directly machining cam driving lubricant pump is realized lubricating on the input bent axle, has saved vertical use need mechanisms such as additional bevel gear drive, chain-driven on horizontal basis in the known technology.
