Abstract
A connecting-rod tooth-engaging type speed reducing and changing device is formed by combining connecting rod mechanisms and engaging transmission mechanisms. The connecting-rod tooth-engaging type speed reducing and changing device comprises a plurality of eccentric connecting-rod mechanisms which are uniformly distributed along the circumferential direction. A gear tooth is equipped on the top of each connecting rod. An output ring gear is equipped on the outer sides of the connecting rods. When an input mandrel and an eccentric disc are running, the gear tooth on the top of each connecting rod is then sequentially driven to be engaged with the gear tooth of the ring gear. Then the ring gear is driven to output power. When a fixing eccentric disc is adopted, the device is a decelerator. When a distance-adjusting eccentric disc is adopted, the device is a speed change device. The speed reducing and changing device which has the characteristic of simultaneous engagement of multiple teeth has relatively great transmission power. During a speed change transmission process, the speed reducing and changing device has constant power output characteristics.
Description
Technical field
The utility model belongs to mechanical transmission design and manufacturing technology field.
Background technique
At present, speed reducer generally is to adopt gear mechanism to carry out transmission, but gear mechanism is monodentate engagement stand under load when transmission, so the power that the intensity of monodentate and size directly have influence on gear mechanism to be transmitted; In addition, the velocity ratio that a pair of gear transmission realized is i=3～7 normally, just need to adopt many to gear and increasing volume if requirement increases velocity ratio.So for big speed ratio and high-power transmission, its volume of the gear mechanism of employing, structure just need the phase strain big and complicated.
Mechanical stepless transmission structure, form that speed change gear is used at present are more, but its working principle all is to utilize friction driving basically, so can only transmit less power, is confined to N≤10kw usually, and mostly drive characteristic is permanent torque output.
Summary of the invention
The connecting rod tooth-type speed reducing/changing device that the utility model proposes is combined by linkage mechanism and engagement transmission mechanism; This device is equipped with the eccentric disc that tape spool holds on axle; The along the circumferential direction equally distributed connecting rod pig of the outer surface of bearing and several; The connecting rod lower end links to each other with rocking bar through bearing pin, and the rocking bar the other end is fixed on the frame through bearing pin; The gear teeth are processed on the top of each connecting rod, its outer ring gear that is equipped with; When axle turned round, the corresponding gear teeth with ring gear of gear teeth order that drive on each connecting rod through the eccentric disc bearing carried out engagement driving.
This apparatus features one is that it can process speed change gear again with promptly can be made into speed reducer with a kind of basic system, only needs fixedly eccentric disc to use the roll adjustment eccentric disc instead in this; The 2nd, this device has the characteristics that multiple tooth engagement, monodentate simultaneously carry to reduce when transmission, counts Z >=3～5 with grinding tooth during single-phase transmission, will be multiplied during heterogeneous transmission, therefore can transmit more high-power and volume is less; The 3rd, during as speed reducer, can realize big speed ratio i >=40～50, during as speed change gear, then have constant power output characteristic.

Embodiment
The embodiment of the utility model is as shown in Figure 1:
On input axle 1, be fixed with eccentric disc 2; Be sleeved on rolling bearing 3 its excircles of eccentric disc 2 pig with 8 equally distributed connecting rods 4; Ratchet is processed so that be meshed with ratchet 5 in the top of connecting rod 4; The lower end then is connected with rocking bar 6 through bearing pin, and the rocking bar the other end is fixed on also can be around fixed support 8 reciprocally swingings on the frame 7, and ratchet is through being connected so that output power with the output reel along the screw 9 that circumferentially distributes.
When the running of input axle; Drive eccentric disc and on the axis of rolling make eccentric motion, and each connecting rod that is distributed on the bearing circumference receives driving eccentric and rocking bar, the ratchet order and the ratchet on its top get into engagement; Promote ratchet running outputting power; Withdraw from engagement then, the gearing down process is accomplished in so continuous circulation.
The single-phase transmission that this device can be made up of an eccentric disc and several connecting rods; Also can be two-phase or heterogeneous transmission.
The bearing pin of connecting rod lower end be except can also can linking to each other with slide block with rocking bar links to each other, and with slide block along runner movement.The chute track can be a straight line, also can be circular curve.
The gear teeth on ring gear and connecting rod top can be ratchet and ratchet, also can be involute gear, circular tooth gear or other conjugate gearss.
Each connecting rod all has a Returnning spring.
In device, adopt fixedly eccentric disc, realize gearing down.
Realizing the speed change transmission, mainly is to regulate throw of eccentric, and therefore fixedly eccentric disc is changed into roll adjustment eccentric disc structure, and embodiment is as shown in Figure 2:
This moment eccentric disc 2 be not fixedly be loaded on the input axle 1 but the dish in the middle of open an elongated slot be enclosed within the input axle 1 on and can along the input axle 1 move up and down, between slotted eye and axle the arrangement one inclined-plane voussoir 10.Voussoir can move forward and backward along axle, and its upper surface is connected with eccentric disc through roller 11, and a spring 12 is arranged below axle and between the slotted eye, and its effect is to guarantee that roller is pressed on the voussoir inclined-plane at any time.
Like this, as long as move forward and backward voussoir 10, eccentric disc 2 is also adjusted its throw of eccentric with corresponding moving up and down, and the connecting rod top ratchet that is driven by it also changes the distance that promotes with ratchet engaged thereupon, thereby has realized the speed governing transmission.
The roll adjustment eccentric disc can adopt double eccentric mechanism or mobile cotter mechanism to carry out roll adjustment.
