Description
Technical field
The present invention relates to a kind of driving mechanism, be specifically related to a kind of driving mechanism realizing single-direction transmission between different transmission shaft.
Background technique
When clutch or coupling work, in order to ensure the centering between axle in transmission process and axle, the offset displacement amount in diaxon axle center is all a very little scope, power input unit, power output unit and clutch (or coupling) integrally exist, and generally have higher position accuracy demand.For some large scale systems, as the egg pick up system that breeding layer chicken field is arranged, be made up of multiple egg collection device be arranged in plant, each egg collection device needs to arrange power input unit and power output unit, the power input unit of egg collection device and the defeated unit of power are by coupling or chain connection for transmission, because the frequency of utilization of each egg collection device is not high, too high lness ratio of plant causes the serious wasting of resources, cannot the value of embodiment device, in addition, in large-scale plant, egg collection device use amount is larger, overall investment is larger, certain economic burden is caused to user.
Summary of the invention
The object of this invention is to provide a kind of one-way driving mechanism, to solve the problem.
To achieve these goals, the technical solution adopted in the present invention is:
A kind of one-way driving mechanism, the transmission unit that there is the driving shaft be connected with egg collection device power input unit, the driven shaft be connected with the defeated unit of egg collection device power and be connected with driven shaft with driving shaft, it is characterized in that, transmission unit comprises: the friction cylinder of hollow round table shape, be connected with driven shaft by the first line shaft and the first universal shaft coupling, the little bottom end of friction cylinder is closed, large bottom end opening; And be nested in the friction mandrel of friction cylinder inside, be connected with driving shaft by the second line shaft and the second universal shaft coupling, axle body containing frustoconic shape and the leaf grating be positioned in this axle body circular arc wall, the tapering of axle body is identical with the tapering of friction cylinder, and during normal work, the edge of leaf grating is fitted on the inwall of friction cylinder.
Technological scheme of the present invention is further characterized in that: leaf grating is made up of multiple class parabolic blades, the length of such parabolic blades is identical with the length of the bus of axle body, edge on one side and axle body are fixedly linked, and the edge of relative another side is close to the internal surface of friction cylinder.
Technological scheme of the present invention is further characterized in that: class parabolic blades is manganese steel sheet.
Technological scheme of the present invention is further characterized in that: friction cylinder tall and big in the height of friction mandrel.
Technological scheme of the present invention is further characterized in that: the internal surface of friction cylinder sidewall is smooth.
Compared with background technique, technological scheme of the present invention produces friction by leaf grating axial rotation in friction cylinder, carry out single-direction transmission, when egg collection device line shaft turn to identical with blade lean direction time, blade is due to the effect of frictional force, anterior vanes constantly pushes following vane, this makes it possible to make the inwall of blade laminating friction cylinder more tight, and power transmission is more reliable.Realize the power transmission of diaxon, when friction mandrel turn to contrary with the sense of rotation of blade time, the inwall of blade and friction cylinder only has a small amount of scratching, and does not have enough frictional force to realize the transmission of diaxon.The similar following operation of above-mentioned working principle: by the tapered paper web of several A4 paper rolls, and at paper web outer wrapping a piece of paper; When this taper paper web rotates towards paper sense of rotation, taper paper web and outer paper have faint frictional force effect, if but rotate towards the opposite direction that paper web paper rotates, because paper web paper outwards expands, make between paper web and outer paper, to have a very large frictional force effect.Its advantage and good effect as follows:
1. egg collection device power input unit can meet the demand of the defeated unit of multiple egg collection device power
Friction mandrel due to technological scheme of the present invention is nested in friction cylinder inside, when be in not using state time, easily friction mandrel can be extracted from friction cylinder inside, therefore, when using driving mechanism provided by the present invention, driving shaft is connected with egg collection device power input unit, driven shaft is connected with the defeated unit of egg collection device power, when the defeated unit of egg collection device power needs power, friction mandrel is nested in friction cylinder, transmission can be carried out, when not needing power, friction mandrel and friction cylinder are separated, egg collection device power input unit after separation can need the egg collection device power of power defeated unit supply power to other, thus the power demand of the defeated unit of multiple egg collection device power only can be met with an egg collection device power input unit, substantially increase the utilization rate of egg collection device power input unit.
2. alignment degree is good, and coaxality is high
Between when an egg collection device power input unit is back and forth in the defeated unit of some egg collection device power, do not need clutch and coupling, by the structure of self frustoconic shape, friction mandrel and friction cylinder can automatic capturings, the two is made to reach higher alignment degree, further, the tapering of the two is identical, and nested rear coaxality is high.
3. connect stable
Owing to being friction driving between friction mandrel and friction cylinder, excessive mechanical structure is not had to impact, and, also with universal shaft coupling with the use of, can adjust angle by steering structure, be controlled by the angular dependence that sets, the angle in friction mandrel and friction cylinder moving process is catered to.The mechanism of adjustment angle realizes locating by the steel ball on slide block and the groove fit on axle, then produces pulling force by the spring in this mechanism, gets back to working position accurately after every task.Therefore drive mechanism can realize carrying out stable connection when egg collection device moves.Can meet and cannot realize in highi degree of accuracy control situation, avoid mobile device frequent starting in moving process, damage motor, this egg collection device egg collection device power input unit can along predefined trajectory walking under PLC controls, and when touching position limit switch, egg collection device power input unit stops mobile.Due to the single-direction transmission function of friction type one-way driving mechanism, the harm produced when this mechanism can also avoid motor to rotate backward.
