Description
Technical field
The utility model belongs to chain-linked conveyer technical field, is related to a kind of worm drive.
Background technology
Chain-linked conveyer uses very extensive in mechanization conveying industries.In the prior art, conveying Chain conveyer all makes mostly
Driven with Track Type, or be driven by transportation sprocket.Transmission efficiency is low, and noise is big.
The content of the invention
The utility model is in view of the above-mentioned problems, provide a kind of worm drive, the device transmission efficiency, and noise is low.
According to the technical solution of the utility model：A kind of worm drive, including framework, frame head plate surface one end peace
Main reducing motor is filled, main reducing motor drive shaft rotates, and is also rotated on framework and sets worm screw, led between the worm screw and main shaft
Chain is crossed to be connected, it is characterised in that：Lower position on the framework corresponding to worm screw is provided with chain, on chain
For being respectively provided with bearing on bearing pin that adjacent carrier bar is connected, the bearing is engaged with worm screw, realizes the biography of chain
It is dynamic.
As further improvement of the utility model, the frame head plate surface other end installs standby reducing motor, standby
It is connected with the output end of reducing motor with main shaft by second shaft coupling.
As further improvement of the utility model, it is connected between the main reducing motor and main shaft by first shaft coupling
Connect.
As further improvement of the utility model, drive sprocket is installed on the main shaft, the input installation of worm screw from
Movable sprocket, it is connected between the drive sprocket and driven sprocket by chain.
As further improvement of the utility model, the bearing engaged transmission of the worm screw and chain.
It is of the present utility model to have technical effect that：The utility model product structure advantages of simple, passes through the rotation motor
Power is converted into linear transmission power by worm-drive, adds transmission moment of torsion, by worm screw and the bearing engaged transmission of chain, subtracts
Frictional force is lacked, so as to which efficiency greatly improves than conventional worm, transmission efficiency can about reach 95%；Other worm screw and motor it
Between be to have used Chain conveyer, worm screw load force is moved out on driving shaft, is easy to safeguard, and motor buying one drive it is one standby, when
Main motor occurs that during problem standby motor can be quickly switched into, so as to not influence pipeline.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Specific embodiment of the present utility model is further described below in conjunction with the accompanying drawings.
In Fig. 1, including framework 1, main gear reducer 2, first shaft coupling 3, main shaft 4, drive sprocket 5, chain 6, the second shaft coupling
Device 7, standby reducing motor 8, worm screw 9, driven sprocket 10, bearing 11, chain 12 etc..
As shown in figure 1, the utility model is a kind of worm drive, including framework 1, the top board surface one end of framework 1 peace
Main reducing motor 2 is filled, the main drive shaft 4 of reducing motor 2 rotates, and is also rotated on framework 1 and sets worm screw 9, the worm screw 9 and main shaft
It is connected between 4 by chain 6, the lower position on the framework 1 corresponding to worm screw 9 is provided with chain 12, chain
It is used to that bearing 11 will be respectively provided with bearing pin that adjacent carrier bar is connected on 12, the bearing 11 is engaged with worm screw 9, is realized and is conveyed
The transmission of chain 12.
The top board surface other end of framework 1 installs standby reducing motor 8, and output end and the main shaft 4 of standby reducing motor 8 pass through
Second shaft coupling 7 is connected.
It is connected between main reducing motor 2 and main shaft 4 by first shaft coupling 3.
On main shaft 4 install drive sprocket 5, worm screw 9 input installation driven sprocket 10, the drive sprocket 5 with it is driven
It is connected between sprocket wheel 10 by chain 6.
Worm screw 9 and the engaged transmission of bearing 11 of chain 12.
The course of work of the present utility model is as follows：Main reducing motor 2 drives main shaft 4 to rotate via first shaft coupling 3, main shaft
4 drive chains 6 rotate, and chain 6 drives worm screw 9 to rotate, and the bearing 11 close to worm screw 9 in original state, chain 12 is put
In the groove of worm screw 9, when worm screw 9 rotates, band dynamic bearing 11 moves axially along worm screw 9, realizes the action of chain 12.
