Abstract
The invention discloses a screw rod regulation-typed stepless speed change device which is sleeved with a crank on a power input shaft; a driving gear is arranged on an output shaft and sleeved on the output shaft by a one-way bearing; a planker is fixed on the driving gear; a sliding block of the planker is connected with the crank in a transmission way by a connecting rod; one side of the driving gear is also provided with a driven gear which meshes with the driving gear; the driven gear is sleeved on an auxiliary shaft by the other one-way bearing with the same steering direction; on the back surfaces of the driving gear and the driven gear, the output shaft and the auxiliary shaft are fixed with two small gears respectively which transmit by the meshing of a middle gear. When in work, the crank drives the planker to cause the driving gear to make corresponding reciprocating rotation, and the output shaft is driven by the gear mechanism to rotate continuously. By regulating the swinging working radius of the planker, the transmission ratio between the input shaft and the output shaft is changed. The device transmits by the connecting rod and a swing arm, and has large transmission torque and small loss in the transmission process.
Description
Technical field
The present invention relates to speed changer, particularly a kind of stepless speed variator.
Background technique
Present stepless speed variator has belt or forms such as steel band stepless speed variator, awl dish planetary stageless speed variator, all by friction driving.Because easily skid between friction means, thereby driving torque is little, is example with automobile CVT speed changer, the Maximum Torque that can reach is 300N.m at present; In addition, owing to need provide pressure to friction means, the friction means deformation factor has caused power transmission loss bigger.
Summary of the invention
The object of the invention is to provide a kind of stepless speed variator of non-friction driving of high pulling torque.
The solution of the present invention is: screw mandrel regulation type stepless transmission apparatus, comprise power input shaft, output shaft, crank, connecting rod, gear, it is characterized in that: sheathed crank on the power input shaft, output shaft is provided with driving gear, driving gear is set on the output shaft by a unilateral bearing, on driving gear, be fixed with a planker, the support of planker is fixed on the driving gear along the radial direction of driving gear, the slide block of planker is provided with a fulcrum, this fulcrum and crank are in transmission connection with connecting rod, side at driving gear also is provided with the driven gear that is engaged with, driven gear is set on the auxiliary axis by another identical unilateral bearing that turns to, the back side at driving gear and driven gear, output shaft, also be fixed with two small gears on the auxiliary axis respectively, be respectively driver pinion and driven small gear, they are by an intermediate gear engagement driving.
Above-mentioned planker adopts electronic planker, the motor of electronic planker and control circuit control connection.
Advantage of the present invention is: during work, crank drives the planker reciprocally swinging, because it is fixed on the driving gear, so driving gear is also done corresponding back and forth rotation, in the rotation of a direction, unilateral bearing blocks, and driving gear drives output shaft and rotates; In the rotation of another direction, owing to slide between the Internal and external cycle of unilateral bearing, driving gear can not drive output shaft and rotate, but this moment, driven gear can rotate by the unilateral bearing drive auxiliary axis of the inside.These three small gears that rotate by the back side drive the output shaft rotation.How the action of comprehensive these two parts swings regardless of planker, always output shaft rotates towards the direction of setting.Because the radius of clean-up of planker swing can change, and the arm of force length of the crank on the input shaft is fixed, so can change the velocity ratio between input shaft and output shaft.This device is by connecting rod, swing arm transmission, and driving torque is big, and loss is little in the transmission process.
Description of drawings
The invention will be further described with embodiment with reference to the accompanying drawings below.
Fig. 1 is a Facad structure schematic representation of the present invention.
Fig. 2 is the rear view of Fig. 1.
Mark among the figure: 1 input shaft, 2 cranks, 3 connecting rods, 4 screw mandrels, 5 fulcrums, 6 driving gears, the support of 7 plankers, 8 motors, 9 driven gears, 10 ratchets, 11 auxiliary axiss, 12 driven small gears, 13 jack shafts, 14 intermediate gears, 15 driver pinions, 16 output shafts.
Embodiment
In conjunction with Fig. 1 and Fig. 2, embodiment's screw mandrel regulation type stepless transmission apparatus, sheathed crank 2 on the power input shaft 1, output shaft 16 is provided with driving gear 6, driving gear 6 is to be set on the output shaft 16 by a unilateral bearing, on driving gear 6, be fixed with a planker, the support 7 of planker is fixed on the driving gear 6 along the radial direction of driving gear 6, the slide block of planker is provided with a fulcrum 5, this fulcrum 5 and crank 2 are in transmission connection with connecting rod 3, when crank rotated, planker was just made left and right sides reciprocally swinging.
Side at driving gear 6 also is provided with the driven gear 9 that is engaged with, and driven gear 9 is set on the auxiliary axis 11 by another identical unilateral bearing that turns to 10.
At the back side of driving gear 6 and driven gear 9, also be fixed with two small gears on output shaft 16, the auxiliary axis 11 respectively, be respectively driver pinion 15 and driven small gear 12, they are by intermediate gear 14 engagement driving.
During work, crank 2 drives plankers 7 reciprocally swingings, because the support 7 of planker is fixed on the driving gear 6, so driving gear 6 is also done corresponding back and forth rotation.
In the rotation of a direction, clockwise direction as shown in Figure 1, unilateral bearing blocks, and driving gear 6 drives output shaft 16 and does the clockwise direction rotation.
When driving gear 6 was done counterclockwise to rotate, owing to slide between the Internal and external cycle of unilateral bearing, driving gear 6 can not drive output shaft 16 and rotate.
This moment, it can drive auxiliary axiss 11 by the unilateral bearing 10 of the inside do the clockwise direction rotation because driven gear 9 is done the clockwise direction rotation.
This rotates driver pinion 15, intermediate gear 14, driven small gear 12 by the back side, drives output shaft 16 and does the clockwise direction rotation.
How the action of comprehensive these two parts swings regardless of planker, always output shaft 16 rotates towards the direction of setting.
Because pushing away, draw and acting on of connecting rod 3 is to act on the slide block of planker, moving of slide block can be regulated the radius of clean-up that planker is swung, and the radius of clean-up of crank is fixed on the input shaft, so the mobile velocity ratio that can change between input shaft and output shaft of slide block.
In order to regulate velocity ratio continuously when working, planker adopts electronic planker, with its motor 8 and correspondent control circuits control connection, just can realize automatically controlled adjusting or intelligent control.
