Description
The utility model relates to the differential Gear Planet Transmission speed changer of friction, particularly ring awl differential planetary stageless speed variator.
In the prior art, as stepless speed variators such as MBWy type, XZW type, JW-LZ types, can only stepless speed regulation in 200-1000 rev/min of scope, if the user need work below 200 rev/mins, even the requirement that has is when working in 0.5-100 rev/min of scope, just must join various speed reducer in addition, so not only expense is big, and increases coupling arrangement, form structure complexity, bulky, bring difficulty to installation.
The purpose of this utility model provides a kind of ring awl differential planetary stageless speed variator, and the braking technique and the mechanical friction stepless change of large speed ratio are combined dexterously, can make speed change within 0.5-1000 rev/min of scope.
The utility model is that following mode is finished: known Friction Stepless device and planet one tooth difference transmission mechanism are combined.Connect with ball with welding cam in the middle of it, become as a whole.
The Friction Stepless device is selected to be made up of input disk, planetary cone wheel, speed ring, output disk and worm-and-wheel gear, and planet one tooth difference transmission device is made of sun gear in middle eccentric shaft, differential teeth planetary wheel and the tooth difference.Its working surface of welding cam that connects between the two is a curved surface, and pressure angle is variable, permanent power output when making work.When motor drives input disk drives the planetary cone wheel rotation by friction driving, and revolve round the sun along the speed ring inner ring, make output disk produce widely different commentaries on classics, eccentric shaft rotation in the middle of driving by welding cam again, at this moment as long as handle worm-and-wheel gear speed ring is moved axially, change the size of the contact radius of cone pulley, eccentric shaft can obtain different rotating speeds then, utilize a gear difference planetary driving mechanism then, on middle eccentric shaft, put cycloid wheel or the involute planetary wheel or the harmonic gear of the suitable number of teeth, oscillating tooth fluctuation wheel, pin shape oscillating tooth gear or the like is meshed with fixedly pinwheel or involute internal gear, makes output shaft obtain the mechanical transmission of variable low-speed big.Its arrangements for speed regulation ordinary circumstance is to drive worm-and-wheel gear with handwheel.Can handle at four, five meters as changing into flexible shaft operation,, even adopt the remote control unit operation if operation automatically can also be adopted the actuating motor device.
The utlity model has large speed ratio and slow down and infinite variable speed two-fold advantage, slewing range is 0.5-1000 rev/min of stepless speed regulation.Compact structure reduces expense again, can replace electromagnetic adjustable speed motor under identical output torque, and the input power of motor can reduce 40%, and expense can reduce by 35%, and can not shut down speed governing.As be used in the ball milling carousel, can make output torque increase several times and realize stepless speed regulation again.1.1KW Slipper motor of the original application of Shanghai unit, its output torque is 7.1Nm, slewing range can only be within 1250-125rPm, because rotating speed is also high, have to adopt v belt to drag the transmission of a 1:40 worm speed reducer, expense reaches 3,000 yuan approximately, and profile is huge.After adopting the utility model, output torque is 7-23Nm, and output speed is 0-40rPm by customer requirements, and the expense of this ball milling carousel is kept to below 2000 yuan, and saving power.(after adopting the utility model, power of motor is reduced to 0.75KW) and for example Pingyang factory on filling bottle wine automatic transport band, originally use the 2.2KW motor, drag a worm speed reducer, power consumption is speed change arbitrarily greatly again, after using the utility model, power is reduced to 0.75KW, clearly saving power.In the same time, every day, two classes of work were calculated, and annual economize on electricity more than 7,000 is spent, then with regard to the expense of recoverable equipment investment.Not only cancel big motor and worm speed reducer, and the reduction means volume reaches the purpose of any speed change again greatly.
The utility model will further describe in conjunction with the accompanying drawings.
Fig. 1 is the whole sectional view of the utility model.
With reference to Fig. 1: the utility model is by sun gear (9) in input disk (1), planetary cone wheel (2), speed ring (3), output disk (4), welding cam (5), middle eccentric shaft (6), worm-and-wheel gear (7), differential teeth planetary wheel (8), the tooth difference, and output shaft (10) is formed.The Friction Stepless device is exactly to be made of input disk (1), planetary cone wheel (2), speed ring (3) and output disk (4), worm-and-wheel gear (7), one gear difference planetary driving mechanism is exactly by sun gear formations such as (9) in middle eccentric shaft (6), differential teeth planetary wheel (8), the tooth difference, between a Friction Stepless device and a tooth-difference planetary transmission, there is welding cam (5) to connect.This welding cam (5) working surface make pressure angle variable, and general existing welding cam is the tapered plane form as the curved surface form, and its pressure angle is fixing.Using the automatic welding cam device of curved surface is permanent power output when making work, and the mobile position of speed ring (3) is to be controlled by worm-and-wheel gear (7).The conical surface of speed ring (3) and planetary cone wheel (2) can reduce how much and slide with a touch scrolling friction, increases work efficiency.
There is the fixing ball (11) of retainer to play the pin effect between welding cam (5) and the output disk (4), go up hollow at the joining axle of output disk (4) spring (12) partly is housed, in order to give output disk (4) initial pressure, make it to contact with planetary cone wheel (2) all the time.Input disk (1) is connected in the speed ring (3) with planetary cone wheel (2) friction and rolls, and produces the planetary differential rotation, and planetary cone wheel (2) is connected with output disk (4) friction again, is connected with welding cam (5) by ball (11).Eccentric shaft (6) in the middle of welding cam (5) connects, middle eccentric shaft (6) is connected with differential teeth planetary wheel (8), and a differential teeth planetary is taken turns sun gear (9) engagement in (8) and the tooth difference, and is connected with output shaft (10).
After motor D starting, drive input disk (1) rotation, planetary cone wheel (2) rotation this moment, and, make output disk (4) produce differential widely different commentaries on classics along the revolution of speed ring (3) inner ring, eccentric shaft (6) rotation in the middle of driving by welding cam (5) again, at this moment as long as operation worm-and-wheel gear (7), speed ring (3) is moved axially, change the size of the contact radius of planetary cone wheel (2), then middle eccentric shaft (6) can obtain different rotating speeds.The differential teeth planetary wheel (8) that puts the suitable number of teeth on middle eccentric shaft (6) is meshed with sun gear (9) in the tooth difference, thereby makes output shaft (10) obtain variable low-speed big mechanical transmission.
One differential teeth planetary wheel (8) can be cycloid wheel or involute planetary wheel or harmonic gear or oscillating tooth fluctuation wheel or pin shape oscillating tooth gear.Sun gear (9) can be pinwheel or gear in the one tooth difference.
