Abstract
A stepless speed changing device of the mechanical transmission device mainly solves the problem that all kinds of mechanical transmission can be adjusted to the optimum speed or the rotation speed of the mechanical transmission, improves the functional reliability and the operation convenience, and reduces the energy consumption. The main composing of the stepless speed changing device is characterized in that a crank 12 can be adjusted in the radial direction on the eccentric sheave 1; a toothed rack 5 is made to move up and down and to and fro by a speed changing lever 2, gear wheels 6 and 7 are driven to rotate and a gear wheel 17 is made to export energy, and a shaft 18 displaces vertically and alters the fulcrum phasemass by following the gear wheel 3. The stepless speed changing device has advantages that the stepless speed changing device uses the gear wheel as the transmission, speed regulation and output, the balance of the driving force is provided, the power is large, the mechanization and the automatization are easily realized, and the speed changing ability of the mechanical transmission is improved.
Description
The utility model relates to a kind of mechanical transmission, is a kind of transfer point gear power transmission stepless speed variator.
At present, equipment such as domestic a lot of traffic tool and various lathes adopt stepped transmission case or step change transmission, its objective is and change driving torque into stepped increasing or decreasing moment, its formation is by several axles and some gear pair is carried out the gear shift speed governing, can not dynamic transmission when its deficiency is gear shift, be difficult to select optimum speed or speed, complicated operation, easily cause phenomenon out of supply.
The purpose of this utility model is mainly to solve: adapts to the selection of all kinds of mechanical transmission optimum speeds or rotating speed, reduces the consumption of energy, and easy to operate, and can improve the reliability of work.
The utility model can reach by following measure: crank 12 is radially adjustable on eccentric wheel 1, and cooperate with groove on the speed change lever 2, axle 18 1 ends cooperate with slideway 15 by speed change lever 2 groove running in bearingss, axle 18 the other ends are by gear 3 and tooth bar 11 interlocks, speed change lever 2 both lateral sides " protruding " go out with ground way 4 to cooperate, speed change lever 2 dops 10 are by screw assembling tooth bar 5, with two side gear 6 interlocks in the same way, gear 6 and 7 is assemblied in axle 16 two ends respectively, and is installed on the frame 13 by 8 one-tenth biconjugates of bearing.
The utility model can also reach by following measure: gear 6 is unidirectional inclined-plane gear or unidirectional flywheel 19.Tooth bar 5 and ground way 4 are arc.
Accompanying drawing drawing of the present utility model is described as follows:
Fig. 1 is a plan view of the present utility model.
Fig. 2 is a plan view of the present utility model.
Fig. 3 is the utility model middle rack 5 and the partial sectional view during interlock mutually of flywheel 19 in the same way.
Fig. 4 is the utility model middle rack 5 and the partial sectional view during interlock mutually of gear 6 in the same way.
Fig. 5 is the sectional view of speed change lever ground way in the utility model.
Above number in the figure is meant:
The 1-eccentric wheel, 2-speed change lever, 3-speed change gear, 4-speed change lever ground way, 5-curved racks, 6-gear, the 7-gear, 8-bearing, 9-axle, the 10-dop, 11-speed change tooth bar, 12-crank, the 13-frame, 14-input shaft, 15-slideway, 16-axle 17-output gear, 18-axle, 19-flywheel.
The utility model is further described below in conjunction with accompanying drawing:
From Fig. 1 and Fig. 2, find out, input shaft 14 outer ends can link with speed reducer or motor, its inner assembling eccentric wheel 1, crank 12 is radially adjustable on eccentric wheel 1, and cooperate with groove on the speed change lever 2, axle 18 1 ends are by the another groove on the speed change lever 2, and running in bearings cooperates with slideway 15, and axle 18 the other ends pass through gear 3 and tooth bar 11 interlocks; Speed change lever 2 both lateral sides " protruding " go out with ground way 4 to be slidingly matched, speed change lever 2 dops 10 are by the curved tooth bar 5 of screw assembling, with two side gear 6 interlocks in the same way, gear 6 and 7 is assemblied in axle 16 two ends respectively, and be installed on the frame 13 two side gears 7 and output gear 17 interlock mutually by 8 one-tenth biconjugates of bearing.Trend of work of the present utility model is such, when 14 rotations of driven by motor input shaft, crank 12 is made the circumference uniform motion, speed change lever 2 is pumped simultaneously, 18 point actions of axle, speed change lever 2 the other end dops 10 and tooth bar 5 pump thereupon, because tooth bar 5 has lateral clearance, when moving downward, referring to Fig. 4, right gear 6 is rotated counterclockwise, when tooth bar 5 moves upward, driving left gear 6 is rotated counterclockwise, simultaneously, corresponding left and right sides gear 7 all is rotated counterclockwise, thereby the output gear 17 of interlock is turned clockwise, export as power, and speed change is moved along spur rack 11 mainly by speed change gear 3, to change the position of the fulcrum of speed change lever 2, thereby change tooth bar 5 speed that moves up and down, reach the purpose of stepless output variable speed.
The utility model is compared with existing technology has following advantage:
(1) can make the vehicles such as automobile and other machine driving select optimum speed whenever and wherever possible, reduce reactive power consumption, energy savings, and when speed change, also can not stop working.
(2) speed change at the uniform velocity changes, and reduces noise and unnecessary wear and tear in machines, 1～20 times of its slewing range.
(3) owing to adopting gear, so driving force is steady, power is bigger as transmission, speed governing and output.
(4) this machine is easily realized automation, mechanization; Complete machine structure is simple, be easy to make, and is easy to use.
Claims (4)
1, a kind of stepless speed variator, comprise frame 13, gear pair, it is characterized in that: radially adjustable crank 12 is arranged on eccentric wheel 1, cooperate with the groove on the speed change lever 2, axle 18 1 ends cooperate with slideway 15 by speed change lever 2 groove running in bearingss, axle 18 the other ends are by gear 3 and tooth bar 11 interlocks, speed change lever 2 both lateral sides " protruding " go out, cooperate with ground way 4, speed change lever 2 dops 10 are by screw assembling tooth bar 5, with two side gear 6 interlocks in the same way, gear 6 and 7 is assemblied in axle 16 two ends respectively, and is installed on the frame 13 by 8 one-tenth biconjugates of bearing.
