Abstract
The utility model discloses a gear stepless speed change device, which comprises a helical gear 11, a special angle gear 3, elliptic gears 2, 12, 14 and 15, a gear 13 and a worm gear and worm speed regulating mechanism; the utility model is used on an automobile, and has the advantage of an advanced hydraulic machine speed change device. The utility model has the advantages of simple structure, convenient maintenance, high efficiency, small load speed change power wastage, simple electric control, etc.; the gear stepless speed change device is applied to stepless gear of the traffic, mechanism device and instrument, such as an automobile, an electric car, a train, a marine vehicle, an aircraft, military industry, architecture, textile, food product, chemical industry, electric work, hoisting, etc.
Description
The utility model is to adopt gear to do stepless change, and solving mechanical transmission, particularly high-power machinery communications and transportation etc. needs stepless change and the infinite variable speed problem of load.
Use stepless change to be example with automobile.The prior mechanical stepless speed-regulating device can not adapt to the stepless change requirement of automobile.Advanced Hydromechanical transmission can only use on small-sized and compact car, and efficient has only about 45%.
The utility model provides the device that solves this technical barrier.Its energy load speed change; The variable-speed dynamic loss is little; Transmission efficiency can reach about 90%; Simple in structure; Adapt to powerful load speed change.
The infinite variable speed purpose of the utility model is achieved in that Fig. 1 a.Adopt spiral gear 11, the footpath is parallel to shaft axis O-O ' in the engagement; Lead angle axially and is radially all arranged; Tooth circular pitch equates; Tooth is garden post straight-tooth, helical teeth or helical tooth; Profile of tooth is involute, garden arc or cycloidal tooth profile and 3 engagements of special angle gear.Special angle gear 3 moves special angle gear 3 speed changes along direction as shown.Rotating speed by:
n
Min=(the Z helical tooth opinion small end number of teeth)/(the special angle of the Z gear number of teeth) fades to
n
Max=(Z
The helical tooth opinion small end number of teeth)/(Z
The special angle gear number of teeth)
The utility model Fig. 1 b.Spiral gear 11 lift angle β equate that increment △ f equates.Not during speed change: special angle gear 3 is at O
1-O
1' axial position is motionless, the meshed center distance △ A of special angle gear 3 and spiral gear 11 changes with the variation of lift angle β.
The utility model Fig. 1 b, Fig. 2.Adopt a pair of identical ellipse garden gear that I shaft drive II axle or II shaft roller are rolled on I crown of roll axle and carry out displacement, adjust the centre distance of II axle and I axle, realize the purpose that special angle gear 3 and spiral gear 11 mesh.
The utility model Fig. 2, II axle are many groups.Power is by spiral gear 11 inputs, and spiral gear 11 drives 3 rotations of special angle gear; Simultaneously, ellipse garden gear or corresponding ellipse garden gear or the roller 2,14 of cam 12,15 drives that is fixed on the I axle makes II axle displacement.Special angle gear 3 drives II to the 13 whole speed back outputs of I shaftgear.
The utility model Fig. 3.Adopt the worm and gear speed regulating mechanism.Rotate when rotary worm 5 makes worm gear 6, drive support 1 and make gear 8, make screw mandrel 9 promote the engaging position that shifting block 4 moved, changed special angle gear 3 and spiral gear 11 by nut 10 around gear 7 rotations.Reach the purpose of speed governing.
Claims (4)
