Abstract
To overcome the defect that existing gear high pair load-carrying ability is relatively low, the low pair of gear that the present invention is provided, it slides transmission power with plane flank profil, can greatly improve the Unit Scale load-carrying ability of gear driving pair.The present invention includes oscillating tooth gear and gear pair, oscillating tooth wheel and rack pair, oscillating tooth bar and gear pair.Its oscillating tooth is that two ends have gudgeon, and flank profil is plane.
Description
Technical field
The invention belongs to Power Machinery Engineering field.
Technical background
Existing gear-profile is all curved surface, and the power delivery mode of its linear contact lay High Voltage limits its load-carrying ability and existed
Further improved in Dedenda's bending stress License Value, it is impossible to meet some requirement of engineering.
The content of the invention
The need for meeting small yardstick big load gear power transmission, the present invention provides a kind of low pair of gear, and it includes tooth
Wheel, gear pair, gear, rack pair, rack, gear pair.Gear, gear pair include two pitch wheels, wherein a gear
For oscillating tooth gear, there is gudgeon at the oscillating tooth two ends of the oscillating tooth gear, and flank profil is plane, and the flank profil of another gear is plane；Gear, rack pair
Including pitch wheel, rack, its middle gear is oscillating tooth gear, and there is gudgeon at its oscillating tooth two ends, and flank profil is plane；Rack, tooth
Wheel set includes pitch wheel, rack, and its middle rack is oscillating tooth bar, and there is gudgeon at its oscillating tooth two ends, and flank profil is plane.It is described
The wheel disc of oscillating tooth gear is groove wheel disc, and the bar of the oscillating tooth bar is groove bar, their the uniform oscillating tooth gudgeon of the wall of groove two
Bearing.The oscillating tooth swings in oscillating tooth wheel disc or the groove of oscillating tooth bar and caters to engaging tooth, the laminating of two flank of tooth is slided power transmission,
Its movable teeth gudgeon shearing resistance allowable stress is much larger than linear contact lay allowable stress, can significantly improve gear capacity, increases gear
Modulus can significantly reduce gear yardstick.
Brief description of the drawings
Accompanying drawing is the secondary schematic diagram of rack.
In figure：1- oscillating tooth wheel discs, 2- oscillating tooth wheel disc grooves, 3- oscillating tooths, 4- racks.
Embodiment
The secondary embodiment of gear, rack.As shown in drawings, oscillating tooth wheel disc 1 forms for two panels identical disc is coaxially affixed, its
The uniform oscillating tooth ball socketed bearing in periphery.Oscillating tooth 3 is placed in the two discs engaging process in the groove 2 between two disc.It is living
The tooth form requirement of tooth 3：The gudgeon of oscillating tooth 3, which is tried one's best, to be placed at the top of its increment, and the transverse tooth thickness and tooth height of rack 4 meet it and nibbled with oscillating tooth gear
During conjunction, the axle center of oscillating tooth 3 is less than engaging tooth tooth top, good fit during ensureing two tooth flank of tooth power transmissions, reasonable power transmission.In oscillating tooth wheel disc
There is damping of the malthoid as oscillating tooth 3 in groove 2 again, reduce and excessively swing and vibration noise.The depth of oscillating tooth wheel disc groove 2 is met
Oscillating tooth is parked in optimal initial tooth matching angle under the action of the centrifugal force.
Claims (2)
