Description
One, technical field
The present invention relates to speed change gear, particularly a kind of large speed ratio gear stepless variable drive.
Two, background technique
Deceleration and speed change are all trades and professions, the necessary transmission part of various engineering goods.It subtracts/and speed change is a kind of motion of complexity, and the complicated problems especially that commutates is not shut down in particularly large speed ratio stepless change.Usually subtracting speed change is to subtract speed change by the power input system to add manual shift fork, and the gearshift of one-level one-level just can be finished, and needs 4,5 grades of just finishing more than 10 grades of having of conversion, and gearshift is complicated especially, the different gear shift complexity of form difference.As vertical gearshift, must just finish with hydraulic pressure installation is auxiliary.Gear shift must be with a large amount of gears and gearshift step by step, and the cost height is wasted the resource and the energy.And must shut down gear shift, buty shifting just must frequently stop starting electrical machinery, wastes energy more.Commutation also must be shut down, because mechanical motion has inertia, shuts down commutation and wastes energy more.So; the large speed ratio stepless change, not shutting down gear shift, commutating is the dream and the ideal of domestic and international mechanical industry specialists, existing both at home and abroad stepless speed variator is to realize with the friction of tapering dish; power is very little; velocity ratio is also little, and generally about one to three ten, power loss is very big; and application area is very little; complex structure, cost height, the waste resource and the energy.Therefore, how to solve the large speed ratio gear stepless change, not shutting down gear shift, commutating is the technical barrier that always will solve in the industry.
Three, summary of the invention
At above-mentioned situation; for overcoming the prior art defective; the present invention's purpose just provides a kind of large speed ratio gear stepless variable drive; can effectively solve the large speed ratio stepless change; do not shut down gear shift; commutation; the problem of energy saving; the technological scheme of its solution is; the present invention includes main motor; speed-adjustable motor and casing; main motor; the speed-adjustable motor symmetry is contained on the wall of the casing left and right sides; gear chamber is arranged in the casing; symmetry is equipped with Intermediate bevel gears about in the gear chamber; the drive bevel gear that is meshed with Intermediate bevel gears is housed on the motor shaft of main motor; the speed governing bevel gear that is meshed with Intermediate bevel gears is housed on the motor shaft of speed-adjustable motor; the gear shaft of Intermediate bevel gears is equipped with output gear in two ends up and down; output shaft laterally is housed in the casing of gear chamber bottom; the output selectiove speed gear that is meshed with output gear is housed on the output shaft; speed-adjustable motor drives the speed governing bevel gear and does counterrotating; the restriction drive bevel gear; the speed of Intermediate bevel gears and output gear makes the speed governing bevel gear produce displacement to opposite direction and reaches deceleration.Novel structure of the present invention, uniqueness, simple; moment of torsion is big; easily produce; cost is low, can not shut down speed change, commutation, economizes on resources greatly and the energy; solved the big technical barrier on the speed change gear (equipment) that long-term people wish to solve; be an original great revolution in speed change field, and bring the breakthrough on the performance and leap that economic and social benefit is huge.
Four, description of drawings
Accompanying drawing is structural front view of the present invention (casing is cut open).
Five, embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is done detailed explanation.
Provide by accompanying drawing, the present invention includes main motor, speed-adjustable motor and casing, main motor 1, speed-adjustable motor 2 symmetries are contained on casing 10 left and right sides walls, gear chamber 6 is arranged in the casing 10, symmetry is equipped with Intermediate bevel gears 5 about in the gear chamber 6, the drive bevel gear 3 that is meshed with Intermediate bevel gears 5 is housed on the motor shaft of main motor 1, the speed governing bevel gear 4 that is meshed with Intermediate bevel gears 5 is housed on the motor shaft of speed-adjustable motor 2, the gear shaft of Intermediate bevel gears 5 is equipped with output gear 9 in two ends up and down, in the casing 10 of gear chamber 6 bottoms output shaft 12 is housed laterally, the output selectiove speed gear 11 that is meshed with output gear 9 is housed on the output shaft 12, speed-adjustable motor 2 drives speed governing bevel gear 4 and does counterrotating, restriction drive bevel gear 3, the speed of Intermediate bevel gears 5 and output gear 9 makes speed governing bevel gear 4 produce displacement to opposite direction and reaches deceleration.
In order to keep in repair and easy to use and using effect, said gear chamber 6 is contained in the casing 10 on the wall of the left and right sides through gear chamber left side spring bearing 8 and the right spring bearing 7 of gear chamber; Speed governing bevel gear spring bearing 14 is arranged between speed governing bevel gear 4 and gear chamber inwall, between drive bevel gear 3 and gear chamber inwall drive bevel gear spring bearing 13 is arranged; The gear shaft of the motor shaft of main motor 1 and drive bevel gear 3 is the same axle that is connected as a single entity, and the speed governing axle of speed-adjustable motor 2 and the gear shaft of speed governing bevel gear 4 are the same axle that is connected as a single entity; Said output shaft 12 is in output shaft left and right sides spring bearing 15 is contained in casing 10 tops on the wall of the left and right sides.
Working condition of the present invention is, main motor 1 drives drive bevel gear 3 and rotates, and active force also rotate Intermediate bevel gears 5, gear chamber 6 rotate at a slow speed drive output gear 9 and exports selectiove speed gear 11 and do power and export.Speed-adjustable motor 2 drives speed governing bevel gear 4 and does opposite spin, restriction drive bevel gear 3, and the speed of Intermediate bevel gears 5 and output gear 9 makes it to produce round about slippage, reaches the purpose of deceleration.Fast more output gear 9 speed of speed governing bevel gear 4 rotations are low more, otherwise at a high speed; The speed of speed governing bevel gear 4 surpasses drive bevel gear 3, just commutation of output gear 9, otherwise commutation again.Power can infinitely great design, more than speed ratio 0.5 rev/min～1000 changes/minute.The present invention is that one of domestic and international mechanical industry speed change transmission is created greatly, be existing variable speed drive (equipment) can't compare, effectively promote mechanical industry technology development and progress.
