Description

The full-automatic on-off apparatus

Technical field

A kind of full-automatic on-off apparatus is suitable for doing on the multifunctional machine clockwise and anticlockwise automatic switchover transmission device usefulness, pulverizes on making beating integrated machine and the combined machine especially for novel husk rice and makes automatic clutch.

Background technique

Existing husk rice, pulverize the making beating combined machine and mainly contain two kinds: be a kind of when being rice milling machine work, driven shredder idle running simultaneously, during shredder work, also drive rice milling machine idle running, both caused the excess power loss, manufacturing efficiency is low, also make simultaneously complete machine oscillation and noise big, increase unnecessary wearing and tearing, poor safety performance, two kinds is to adopt two cover overrunning clutchs to be respectively applied for husk rice, on each independent function machine such as pulverizing defibrination, this apparatus structure complexity, bearing capacity and rotating speed rating value are difficult to satisfy its service behaviour requirement, reliability and bad adaptability, the cost of production height, and failure phenomenon in advance often takes place.

Summary of the invention

The purpose of this utility model provides a kind of full-automatic on-off apparatus, accomplish easy and simple to handle, only use a motor, need not change driving belt, can realize smoothly that with smaller volume and lower cost of production multiple function works independently, its structure is ingenious rationally, and is safe and reliable, long service life, the automaticity height.

The core of technological scheme is by designing a kind of new automatic clutch device, be enclosed within on power machine output shaft or other transmission shaft, the right and left of its middle wheel is separately installed with revolver and right wheel, by connecting firmly with key between drive sleeve and output shaft or the transmission shaft, revolver connects with drive sleeve by the clutch shaft bearing and second bearing with right wheel, middle wheel connects with motion thread is movable with drive sleeve, inner shield ring is fixed on clutch shaft bearing in the hole of revolver, first setscrew nut and second setscrew nut are spun on two ends, the left and right sides screw thread of drive sleeve, new automatic clutch device has adopted two ends to wear the middle wheel of reversed dip tooth, right-hand member is worn the revolver of inclined teeth and the right side that left end is worn inclined teeth wheel, middle wheel adopts the power screw duplicate invoice to connect with drive sleeve, on the left side that take turns on the right side of revolver and the right side in this mechanism, uniform left-leaning tooth of difference and Right deviation tooth, and the both ends of the surface of middle wheel uniform Right deviation tooth of difference and left-leaning tooth, the movable spiral transmission that they and middle wheel and drive sleeve are formed, mutual group become on the full-automatic clutch separation with mesh linking mechanism.

The both ends of the surface that the middle wheel and the revolver of full-automatic on-off apparatus docks mutually, the number of teeth of inclined teeth equates that true dip direction is opposite, middle wheel and the mutual both ends of the surface of docking of right wheel, the number of teeth of inclined teeth equates that also true dip direction is also opposite.

Left-leaning tooth in the utility model and Right deviation tooth, the teeth groove that their two between cog form is wideer slightly than profile of tooth, the tooth of middle wheel one end face inserts in revolver or the right wheel end face teeth groove, drive revolver or right wheel rotation work, meanwhile, the tooth of middle wheel another side end face is pushed out teeth groove, break away from engagement, make revolver, right wheel accomplish to enter engagement all the time on one side, another side breaks away from engagement, remains monolateral drive state.

Compared with the prior art, characteristics of the present utility model are simple and reasonable for structure, and it is more safe and reliable to work, longer service life, easy and simple to handle, volume is little in light weight, cost of production is low, has alleviated labor intensity, is applicable on various all-in-one multifunctional machines and the combined machine to use.

The utility model can be used on the power machine output shaft, also can use on the multifunctional machine transmission shaft, both can be applicable to also can be applicable to other machineries on agricultrue sideline production processing machinery and the Other and Agricultural Machines, on traffic machinery, building machinery, textile manufacturing machine.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further: as Fig. 1,2,3,4,5, shown in 6, the full-automatic on-off device is enclosed within on the motor output shaft 1, the right and left of middle wheel 5 is separately installed with revolver 7 and right wheel 3, by being fixedly connected with key 4 between drive sleeve 13 and motor output shaft 1 or other transmission shaft, revolver 7 connects with drive sleeve 13 by the clutch shaft bearing 6 and second bearing 2 respectively with right wheel 3, middle wheel 5 adopts the motion thread activity to connect with drive sleeve 13, inner shield ring 8 is fixed on clutch shaft bearing bearing 6 in revolver 7 holes, first setscrew nut 10 and second setscrew nut 9 are spun on two ends, the left and right sides screw thread of drive sleeve 13, be evenly equipped with Right deviation tooth 12 and left-leaning tooth 11 respectively on the both ends of the surface of wheel 5 during revolver 7 reaches with right wheel 3 interior edge faces, their two adjacent surfaces flute profile true dip directions are opposite.

Working principle is as follows: when motor output shaft 1 counterclockwise rotates, the Right deviation tooth 12 of middle wheel 5 one ends is pushed open by the left-leaning teeth groove inclined-plane on original intermeshing revolver 7 end faces, left-leaning tooth on the other end enters in the teeth groove of butt end broad smoothly, because the profile of tooth on the both ends of the surface is identical, the number of teeth equates, and true dip direction is opposite, be subjected to the effect of inertial force, when the tooth of one end inserts the teeth groove of the other end, a separated end can produce certain end thrust simultaneously, wheel 5 right laterals in the promotion, wheel 5 has played the guiding boosting and has combined the effect that compresses with the drving sprial pair that drive sleeve 13 is formed in this moment, wheel 5 is tightr with the engagement of right wheel 3 in making, drive right wheel and enter normal operation, if antiport, then the both ends of the surface of the former engagement in the right produce thrust mutually, middle wheel 5 is pushed to the left side, in the same way with revolver 7 engagements, drive revolver and enter normal working, in the above automatic reverse clutch process, the reverse profile of tooth and the drving sprial pair that tilt can produce bigger end thrust jointly, one end is pushed open separation automatically, the other end is by automatic compressive engagement, inserted by tooth and the teeth groove of broad is easier, make joint easier to be more convenient, first setscrew nut 10 and second setscrew nut 9 and packing ring have played the effect of location and buffering.

What deserves to be mentioned is that the utility model can be used as a cover independent device and is applied in other all kinds of machine driven systems, it is simple in structure, and is safe and reliable, applied range.
