Abstract
The utility model relates to a transmission is connected to precision planter elbow formula, including two sets of transmission, its characterized in that: transmission all be equipped with the dead eye including combination casing, two sprockets, chain and bearings, combination casing both sides tip, install in the dead eye that corresponds through the bearing respectively two sprocket both sides, connect through the chain between two sprockets, two sets of transmission connect through a connecting axle, the connecting axle is connected with one of them sprocket of two sets of transmission respectively, the utility model discloses an actively the effect is: structural design is reasonable, can adapt to installing and use of in certain limit disalignment distance, does not have the radial pull between the diaxon of two sets of transmission installation back, and can realize multiple drive ratio through assembly relation each other, does not have the phenomenon of jumping the chain, falling the chain, stinging the chain, and the transmission is steady reliable.
Description
Technical field
The utility model is related to agricultural machinery technological field, more particularly to a kind of precision drill elbow formula connection transmission dress
Put.
Background technology
The power transmission of existing precision drill is most of to use short pitch precise roller chain and chain gear transmission, and it is present
Following shortcoming：
1st, occur that two sprocket wheel end faces are misaligned when mounting and adjusting is not in place, easily fall chain and sting chain phenomenon.
2nd, the radial pull of two sprocket wheels is changed by load variations, is also easy to produce spindle nose stretch bending phenomenon and is caused other association portions
The defect that part is damaged.
The content of the invention
In order to solve deficiency of the prior art, the purpose of this utility model is to provide a kind of precision drill elbow formula to connect
Transmission device is connect, traditional chain type of two-wheeled one is changed to the chain type of four-wheel two, in the absence of the phenomenon for jumping chain, fall chain, sting chain.
The utility model solves the technical scheme that its technical problem used：
A kind of precision drill elbow formula connects transmission device, including two groups of transmission devices, it is characterised in that：Described transmission
Device includes combined shell, two sprocket wheels, chain and bearings, and combined shell both side ends are equipped with bearing hole, two sprocket wheels two
Side is arranged in corresponding bearing hole by bearing respectively, is connected by chain between two sprocket wheels, described two groups of transmissions dress
Put and connected by a connecting shaft, one of sprocket wheel of the connecting shaft respectively with two groups of transmission devices is connected.
Described combined shell is made up of two punching press housing docking, and the junction of two punching press housings is provided with sealing ring.
In sum, good effect of the present utility model is：Reasonable in design, is adapted to not coaxial in certain limit
Away from install and use, two groups of transmission devices install after between two axles without radial pull, and can by assembly relation each other
Various gearratios are realized, in the absence of the phenomenon for jumping chain, fall chain, sting chain, stable drive reliability.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is main structure diagram of the present utility model.
Fig. 2 is cross section structure diagram of the present utility model.
In figure：It is 1 combined shell, 2 bearings, 3 first sprocket wheels, 4 chains, 5 connecting shafts, 6 second sprocket wheels, 7 fastening bolts, 8 close
Seal, 9 punching press housings.
Specific embodiment
Implementation method of the present utility model is illustrated by particular specific embodiment below, those skilled in the art can be by this
Content disclosed by specification understands other advantages of the present utility model and effect easily.
As shown in Figure 1, 2：A kind of precision drill elbow formula connects transmission device, including two groups of transmission devices, described biography
Dynamic device includes combined shell 1, the first sprocket wheel 3, the second sprocket wheel 6, chain 4 and bearing 2, and the both side ends of combined shell 1 are equipped with
The hole of bearing 2, the first sprocket wheel 3 and the both sides of the second sprocket wheel 6 are arranged in the hole of corresponding bearing 2 by bearing 2 respectively, the first sprocket wheel 3
And second connected between sprocket wheel 6 by chain 4, the first sprocket wheel 3 and the second sprocket wheel 6 are respectively provided on two sides with for installing bearing 2
Half the circumference of the sleeve where it joins the shoulder；
Two groups of described transmission devices are connected by a connecting shaft 5, connecting shaft 5 respectively with two groups wherein the one of transmission device
Individual sprocket wheel connection, makes to realize that power is transmitted by connecting shaft 5 between two groups of transmission devices.
Described combined shell 1 is made up of two docking of punching press housing 9, and fastening bolt 7 is passed through between two punching press housings 9
It is connected, the junction of two punching press housings 9 is provided with sealing ring 8.
When precision drill elbow formula connection transmission device is used, by mounted two groups of transmission devices mounted in seeder
On active and passive two axles, it is used to realize the transmission agency between two axles, two groups of transmission devices inside are by the first sprocket wheel 3, the
Two sprocket wheels 6 and chain 4 coordinate transmission power, the radial load that mechanical movement load is produced on the first sprocket wheel 3 and the second sprocket wheel 6
Undertaken by combined shell 1, there is no radial pull between two be connected with connecting shaft 5 sprocket wheel.
Preferred embodiments of the present utility model are the foregoing is only, as long as realizing the utility model with essentially identical means
Purpose technical scheme, belong within protection domain of the present utility model.
