Description
Technical field
The utility model relates to speed changer, particularly a kind of cylindrical gears stepless speed variator.
Background technique
Deceleration and speed change are the necessary transmission paries of every profession and trade engineering goods, and it slows down and the synthetic a kind of especially complicated motion of speed change.Particularly the large speed ratio speed change is complicated more.Usually slow down and lean on tooth poor, speed change is leaned on shift fork, and the one-level one-level is slowed down.General speed change need 2 ~ 5 grades, and the needs that have could be accomplished more than 10 grades, and the throw-over device also needs complex appts such as shift fork splined shaft, spline housing, shift fork moving element, supporting part, location, and form is different, the complexity of shifting gears difference.Like vertical speed change gear, must also must could accomplish the condition with hydraulic pressure is auxiliary except that above.Gearshift needs a large amount of gears, support, fixing and movement means step by step, and the high waste of cost efficient resource is shut down the throw-over switching-over, and the motor frequent starting is wasted the more energy.Therefore, large speed ratio cylindrical gears differential variable-speed case is the desirable pursuit of domestic and international mechanical industry specialists.Invented 28 kinds of mechanical stepless transmissions both at home and abroad, all be with awl dish, awl chain drum, V-type adhesive tape and metal V-type band at present, leans on conical surface friction to realize stepless change, and power is little, velocity ratio is little, the frictional heating power loss is big, and application area is little.The high-power gear stepless speed changing of large speed ratio is the technical barrier that always will solve in the industry.
Summary of the invention
To above-mentioned situation, a technical difficult problem such as for overcoming the defective of existing technology, the purpose of the utility model just provides a kind of cylindrical gears stepless speed variator, can effectively solve the continuous stepless speed change, and speed ratio is little, and power is little.
The technological scheme that the utility model solves is; Comprise main motor, casing and speed-adjustable motor; Main motor and speed-adjustable motor are coaxial to be fixed on the box body wall, and the turning circle casing is housed in the casing, on the inherent same straight line of turning circle casing first flexible shaft and second flexible shaft is housed; First gear is housed in the turning circle casing on first flexible shaft; Second gear is housed in the turning circle casing on second flexible shaft, and inherent first flexible shaft of turning circle casing and the second flexible shaft both sides symmetry are equipped with first planet pin and second planet pin, and first planet differential and second planet differential are housed on second planet pin; The third line star differential gear and fourth line star differential gear are housed on first planet pin; Second gear is meshed with the fourth line star differential gear and second planet differential respectively, and first gear is meshed with the third line star differential gear and first planet differential respectively, on external first flexible shaft of turning circle casing the 3rd gear, the 4th gear is housed successively; The 3rd gear is meshed with main motor gear on the main motor, and the 4th gear is meshed with the speed-adjustable motor gear.
The utility model novel structure is unique, and volume is little, and power is big, and speed ratio is big, and moment of torsion is big, and stepless change is the innovation on the transmission device.
Description of drawings
Fig. 1 is the structural principle plan view of the utility model.
Embodiment
Elaborate below in conjunction with the embodiment of accompanying drawing to the utility model.
Provide by Fig. 1; The utility model comprises main motor, casing and speed-adjustable motor; Main motor 3 and speed-adjustable motor 4 coaxial being fixed on casing 1 wall; Turning circle casing 2 is housed in the casing 1; Be equipped with in turning circle casing 2, to be equipped with on first gear, 14, the second flexible shafts 7 on first flexible shaft 5 and second flexible shaft, 7, the first flexible shafts 5 on the inherent same straight line of turning circle casing second gear 17 is housed in turning circle casing 2; Turning circle casing 2 inherent first flexible shafts 5 and second flexible shaft, 7 both sides symmetries are equipped with first planet pin 8 and second planet pin 6; Be equipped with on second planet pin 6 and the third line star differential gear 13 is housed on first planet differential 15 and second planet differential, 18, the first planet pins 8 is meshed with the fourth line star differential gear 16 and second planet differential 18 respectively with fourth line star differential gear 16, the second gears 17; First gear 14 is meshed with the third line star differential gear 13 and first planet differential 15 respectively; The 3rd gear 10, the 4th gear 12, the three gears 10 are housed on external first flexible shaft 5 of turning circle casing successively are meshed with main motor gear 9 on the main motor, the 4th gear 12 is meshed with speed-adjustable motor gear 11.
Described casing 1 is square or circular.
The working condition of the utility model is, main motor 3 starts, and speed-adjustable motor 4 stops; Second flexible shaft 7 slows down as output shaft, and main motor 3, speed-adjustable motor 4 start the output shaft speed change simultaneously, and main motor 3 is big with speed-adjustable motor 4 speed differences, speed ratio is big; Speed difference is little, speed ratio is little; Constant speed can commutate, and realizes stepless change, and the stepless change speed ratio can reach more than the 1:1500; Slow down separately, with a kind of device, speed ratio can reach more than 1 ~ 5000, and moment of torsion is big.
