Background technique
Conventional worm gear and worm gearing come transmitted power by sliding friction, and its transmission efficiency is lower, and it is more serious to wear and tear.During the worm and gear engagement driving, the relative sliding velocity of meshing wheel between cog is big, so frictional loss is big, efficient is low.On the other hand, relative sliding velocity ambassador tooth surface abrasion is serious, heating is serious, in order to dispel the heat and to reduce wearing and tearing, often adopt the comparatively expensive antifriction quality of price and wear resistance material and good lubricating fitting preferably, thereby cost is higher.Its transmission arm of force is little, efficient is low, power loss is big.People began to consider to improve by the structural type that changes worm and gear the transmission efficiency of worm and gear afterwards, groundwork relates to by the some contact of rolling and replaces the slip surface between traditional worm and gear to contact, therefore carried out the research work of replacement worm-gear tooths such as a large amount of use balls, but consider that the higher ball that loads worm screw that makes of general worm screw rotating speed produces centrifugal force and increases the resistance of ball operation, and the unequal meeting of the race way diameter of ball in worm screw causes linear velocity unequal, thereby causes that the ball operation is not smooth.In addition, because the worm screw of this Worm-and-ball transmission device is less, difficulty of processing is bigger.For this reason, industry seeks to develop the innovative Worm and worm-wheel gearing with exploitativeness always.
The model utility content
The purpose of this utility model provides a kind of Worm and worm-wheel gearing of high efficiency new type worm wheel body, frictional loss during with minimizing worm and gear engagement driving, the bearing capacity of raising transmission efficiency and transmission device.
The purpose technological scheme that realizes foregoing invention is:
The Worm and worm-wheel gearing of the utility model high efficiency new type worm wheel body, formed by motor, worm and worm wheel, worm screw is connected with motor output, worm gear is made up of worm gear dish, worm-gear tooth and worm-wheel shaft, described worm-gear tooth is made up of independent monodentate, each independent monodentate is made up of independent bearing pin and a pair of tapered roller bearing, according to worm gear transmission ratio, the relative worm-wheel shaft center line of each independent monodentate circumference formula five equilibrium at interval is fixedly connected in the worm gear dish, namely constitutes the transmission output of this worm-wheel shaft by described worm gear and worm meshing.
The number of teeth of the worm gear of described and worm meshing is at least three, to keep stable drive.
Two described worm wheel symmetrical dislocation are engaged in the worm screw both sides, and the worm-wheel shaft of these two worm gears forms two reversing drive outputs.
Described symmetry dislocation is engaged in two worm gears of worm screw both sides and the dislocation of worm meshing is half pitch.
A worm-wheel shaft with in two worm-wheel shafts of the reverse output of described do meshes another rotating shaft by a pair of gear pair is set, and namely forms the transmission output in the same way of two transmission shafts.
Described two in the same way the end of the transmission shaft of transmission output namely form the rack drives device of being formed by the Worm and worm-wheel gearing of the utility model new type worm wheel body respectively by the wheel and rack engagement.
The utility model is a kind of Worm and worm-wheel gearing of high efficiency new type worm wheel body, the utility model is by the design of innovation worm wheel body, traditional worm and gear transmission is become the cooperation of rolling by being slidingly matched, significantly reduced friction, improved transmission efficiency, under the constant condition of velocity ratio, stable drive, can stablize the bigger torque of output, improve the bearing capacity of transmission device, the utility model is realized two worm-wheel shaft reversing drive outputs by two innovation worm gear both sides dislocation symmetries and worm meshing, and can among the worm-wheel shaft of two reversing drive outputs, add the one-level gear transmission by a worm-wheel shaft, realize that diaxon rotates output in the same way.
The utility model can be applied to space flight, waterborne, land transport facility and various vehicle, also can be applicable in the speed changer in fields such as metallurgy, chemical industry, weaving, machinery.It can replace traditional worm gear and endless screw speed changer, realizes the transmission of high pulling torque, big speed ratio, multistage output, and transmission efficiency can improve more than 40%, and is energy-efficient.
