Description

Bidirectional automatic clutch

Technical field

A kind of bidirectional automatic clutch is adapted to do on the multifunctional machine clockwise and anticlockwise automatic switchover transmission system 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 above motor to be respectively applied for husk rice, pulverize, each independent function such as defibrination, need many repetition component, complex structure, volume increases, the cost of production height, if with a motor, then must manually change driving belt, operation was both required great effort, and was also very inconvenient.

Summary of the invention

The purpose of this invention is to provide a kind of bidirectional automatic clutch, 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, it is rational in infrastructure, ingenious, safe and reliable, long service life, manufacturing efficiency height.

The core of technological scheme is by designing a kind of automatic clutch device: it is installed on the motor output shaft, clutch pinion in the middle of it comprises, connect with the output shaft feather key, both ends of the surface are uniform left-leaning tooth and Right deviation tooth respectively, both ends of the surface profile of tooth true dip direction is opposite, middle clutch pinion both sides are equipped with a dish-like stage clip and a left side, right clutch pinion, a left side, right clutch pinion is by a bolt and a left side, right drive wheel is fixedly connected respectively, adopt bearing to connect with motor output shaft, a left side, the uniform engaging tooth of right clutch pinion interior edge face, its profile of tooth and teeth groove equate with the middle clutch pinion contrate tooth profile groove number that connects, and true dip direction is opposite, positioning step is arranged on the motor output shaft, and the axle external part is provided with holding down bolt and back-up ring.

Left-leaning tooth among the present invention or Right deviation tooth, the teeth groove of their two between cog is wideer slightly than profile of tooth, when wherein meshing on one side after clutch pinion rotates in the middle of helping, profile of tooth is inserted smoothly and is entered drive state in the teeth groove rapidly, at this moment, the tooth of middle clutch pinion one end face inserts in a left side or the right clutch pinion interior edge face teeth groove, drive a left side or right clutch pinion rotation work, meanwhile, the tooth of middle clutch pinion other end is released teeth groove automatically, breaks away from engagement, makes a left side, right clutch pinion accomplishes to enter engagement all the time on one side, another side breaks away from engagement, makes a left side, right drive wheel remains monolateral drive state.

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

The present invention 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 machinery on the agricultrue sideline production processing machinery, on traffic machinery, building machinery.

Embodiment

Below in conjunction with accompanying drawing the present invention is described further: as Fig. 1,2,3, shown in 4, bidirectional automatic clutch is enclosed within on the motor output shaft (13), connect with feather key (15) activity between middle clutch pinion (3) and output shaft (13), its the right and left is equipped with dish-like stage clip (12) and (9), bearing (14) and (6), left side clutch pinion (1) connects firmly with bolt (11) with Left Drive wheel (2), connect with output shaft (13) by bearing (14) again, be evenly equipped with Right deviation tooth (17) and left-leaning tooth (16) respectively on the both ends of the surface of left side clutch pinion (1) and right clutch pinion (5) interior edge face and middle clutch pinion (3), their two adjacent surfaces profile of tooth true dip directions are opposite.

Working principle is as follows: when motor output shaft (13) counterclockwise rotates, produce an end thrust between the left-leaning teeth groove inclined-plane on the Right deviation tooth (17) of interposed clutch (3) one ends and original intermeshing left clutch pinion (1) interior edge face, middle clutch pinion (3) is open, at this moment, originally compressed dish-shaped stage clip (12) also produces certain elastic force, clutch pinion (3) slides to the right along feather key (15) in the middle of promoting, left-leaning tooth on its 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, distribution numbers equates, and true dip direction is opposite, can produce certain axial tension simultaneously in the time of in the teeth groove of the tooth insertion the other end of one end, clutch pinion (3) slides to the right in the middle of the pulling, like this, tightr with the engagement of right clutch pinion (5), by the fastening connection of bolt (10), drive right drive wheel (4) and enter normal operation again.If antiport, then the both ends of the surface of the former engagement in the right produce thrust mutually, and middle clutch pinion (3) is pushed to the left side, with clutch pinion (1) engagement, drive Left Drive wheel (2) and enter normal working in the same way.In the above process, dish stage clip (9) has played the effect that boosting is separated when the automatic reverse clutch with (12), the reverse profile of tooth that tilts can produce end thrust and pulling force, one end is pushed open separation automatically, the other end is strained automatically to be engaged, teeth groove is inserted by tooth then easilier than profile of tooth is wide, makes joint easier to be more convenient, and holding down bolt (8) has played positioning action with back-up ring (7).

What deserves to be mentioned is that the present invention can be used as a cover independent device and is applied in other mechanical legacy system, it is simple in structure, and is safe and reliable, applied range.
