Description
The utility model relates to a kind of transmission device, particularly a kind of roller oscillating tooth gear gear drive that is applicable to low-speed heave-load.
As everyone knows, gear and profile of tooth are divided involute gear, garden gear with curved teeth, cycloidal gear etc., and the centering large gear is then based on involute gear.At present, the fundamental mode of conventional gears transmission is tooth and tooth engagement, is designed to overall structure.Gear be use in the various machineries at most and the maximum base components of technical difficulty, therefore, the technical merit of gear has been represented the mechanical technique level to a certain extent.Though the technology trends of machinery is two different notions with the development trend of gear technique, exists master slave relation.Just the trend of machinery development can reduce high-power, high durability, high even stability, low consumption, purification, satisfy mechanical development trend specific in the gear technique development then being " reinforcement " in the design, " bigization " on the size, large gear diameter number is meter to 20 meters, " stiff doughization " tooth face hardness 58-62HRC in the selection, " refining " accuracy of gear in the processing is up to the 3-4 level.The development trend of gear technique depends on its mechanical development trend, simultaneously be subjected to making machinery heat treatment furnace, gear hobbing machine, skewer tooth machine, the gear grinding machine of gear, the restriction of gear detector again, and these equipment is very expensive.Therefore, traditional gear transmission exposes many birth defects in practice: tooth-tooth engagement produces and slides flank of tooth easy damaged and spot corrosion; Tooth-tooth engagement needs are lubricated, limited gearing and do not allowed the use of the occasion of usefulness oil lubrication at those; And along with " bigization " of gear size, difficulty in the processing and manufacture cost are in remarkable rising.
The roller oscillating tooth gear gear drive that provides a kind of low cost of manufacture, transmission not to have wearing and tearing, need not lubricate is provided the purpose of this utility model.
The utility model is achieved in that a kind of roller oscillating tooth gear gear drive, it comprises intermeshing gearwheel and small gear, it is characterized in that: described gearwheel is made up of roller, bearing, side plate, former, its latus inframedium and former are consolidated, and the two ends of roller are evenly distributed on garden, side plate roller center or the side plate roller center line through the bearing supporting; The roller of described gearwheel is meshed with small gear.
Above-mentioned gearwheel or be external gear, or be internal gear, or be tooth bar.
The side plate of aforementioned external teeth wheel is annular annular side plate, and annular side plate is fixed on the both sides of former; The two ends of roller are evenly distributed on the annular side plate roller center circle through the bearing supporting, and the roller of the roller oscillating tooth gear external gear of Xing Chenging and small gear mesh the roller oscillating tooth gear gear drive of forming the driving of parallel axes on pitch circle like this.When pinion rotation, the tooth of small gear promotes roller, drives external gear by roller and rotates, and the while roller is made trace around the center of oneself and rotated realization transmitting torque and motion.In the transmission, it is constant that velocity ratio keeps, and instantaneous transmission ratio also keeps constant substantially, is pure rolling between the flank of tooth of small gear and the roller, do not slide.
When the side plate of above-mentioned internal gear is annular annular side plate, former is the outer ring that both sides are consolidated with annular side plate, roller is evenly distributed on the annular side plate roller center circle with the bearing supporting, the roller of the roller oscillating tooth gear internal gear of Xing Chenging and pinion are formed the roller oscillating tooth gear gear drive of internal gear transmission like this, form epicyclic gearbox with the planet wheel engagement.
Roller oscillating tooth gear internal gear as epicyclic gearbox can be designed to rotate or fix, and when internal gear rotated, roller drove internal gear and rotates, and does micro-the rotation simultaneously around own center; And when internal gear fixedly the time, roller is only made trace around own center and is rotated, and the motion of planet wheel, planet carrier, sun gear and force mechanism and involute planetary are taken turns roughly the same, and the flank of tooth intercropping pure rolling of roller and small gear or planet wheel in the running does not have slide relative.
The side plate of above-mentioned tooth bar is the front plate of vertical bar shape, former is straight plate, the front plate is consolidated with bolt with straight plate, roller is evenly distributed on the roller center line forms tooth bar, the roller of the roller oscillating tooth gear tooth bar of Xing Chenging and pinion are formed the roller oscillating tooth gear gear drive of rack pinion transmission like this, realize transmitting torque and motion.During moving the commentaries on classics, roller is only made trace around own center and is rotated, and the roller intercropping pure rolling of the small gear flank of tooth and gearwheel is not slided.
The utlity model has following advantage:
1, roller of the present utility model and small gear can be designed to stiff dough, make simply, do not need gear hobbing machine, skewer tooth machine, gear detector, the casehardening furnace of large-scale costliness, and energy saving reduces manufacture cost;
When 2, using the utility model, do not slide between the roller and the flank of tooth, only make pure rolling, so there are not wearing and tearing;
3, the utility model does not need to lubricate, so be specially adapted to large-scale open type transmission device and lubricated difficult occasion;
4, the utility model can be changed by monodentate, and easy to maintenance, maintenance expenses is low, and life cycle cost is low.
