Abstract
The invention relates to a worm-gear anti-reverse mechanism and belongs to the automation equipment technology field. The mechanism comprises a motor, a worm, a turbine and an output shaft. The motor is connected to the worm. The worm is cooperatively connected to the turbine. The turbine is connected to the output shaft. In the invention, brake applications are reduced; through reliable cooperation connection of the worm and the turbine, the output shaft is driven; because the worm and the turbine can not be reversed, output shaft reversal is eradicated completely from a source; and an accident generation frequency is reduced and equipment reliability is increased.
Description
Technical field
The present invention relates to a kind of worm gear anti-reverse mechanism, specifically one kind are prevented from output shaft reversing device, belong to
In technical field of automation equipment.
Background technology
With scientific and technological high speed development, flat display apparatus particularly liquid crystal indicator (Liquid Crystal
Display, LCD) because of it, there is high image quality, small volume, lightweight and applied range, and be widely used in
In all kinds of consumption electronic products such as mobile phone, notebook computer, desktop display device, TV, and little by little replace biography
System CRT display (Cathode Ray Tube, CRT) and become the main flow of display device.In liquid crystal display
In device preparation process, as needed, sometimes need workpiece is rotated.
In prior art, when controlling connecting plate when needing output shaft to connect, motor is directly connected with output shaft, when motor stops
When only, output shaft usually easily inverts, and in order to prevent inverting, needs to install brake between output shaft and connecting plate, but brake
Can not completely prevent output shaft from inverting, the degree of reversion can only be lowered.After being used for multiple times, between output shaft and connecting plate
Still easily get loose because of the screw thread being inverted such that connecting portion, lead to connecting plate to drop.Due to connecting plate weigh more than ten public
Jin, drops and does not closely easily injure equipment by a crashing object, is also easy to security incident.
Content of the invention
It is an object of the invention to overcoming above-mentioned weak point, provide a kind of worm gear anti-reverse mechanism, it can reduce stops
The application of car, prevents output shaft from inverting.
The technical scheme providing according to the present invention, worm gear anti-reverse mechanism, including motor, worm screw, turbine and output shaft, its
Middle motor is connected with worm screw, and worm screw is connected with turbine, and turbine is connected with output shaft.
Described worm screw, turbine are arranged at enclosure, and shell is stretched out in the connection end of output shaft, and motor, against shell, passes through
Shell is connected with worm screw.
Beneficial effects of the present invention：The present invention reduces the application of brake, connected by more reliable worm screw and turbine cooperation
Connect driving output shaft, because worm screw turbine cannot invert, therefore it has prevented output shaft reversion from root, and the accident of reducing is sent out
Raw frequency, improves the reliability of equipment.

Specific embodiment
As Figure 1-3：Worm gear anti-reverse mechanism, including motor 1, worm screw 2, turbine 3 and output shaft 4, wherein motor 1 with
Worm screw 2 connects, and worm screw 2 is connected with turbine 3, and turbine 3 is connected with output shaft 4.
Described worm screw 2, turbine 3 are arranged inside shell 5, and shell 5 is stretched out in the connection end of output shaft 4, and motor 1 is against shell
5, it is connected with worm screw 2 by shell 5.
During present invention work, worm screw 2 is driven by motor 1, worm screw 2 drives turbine 3, finally drives output shaft 4 by turbine 3,
Output shaft 4 is connected with connecting plate, drives connecting plate rotation to complete whole work process.
Due to turbine and worm cannot reverse drive, the therefore present invention prevented the reversion of output shaft from root, improve
The security reliability of equipment.
