Description
Technical field
The utility model relates to a kind of clutch, and especially a kind of friction clutch belongs to the mechanical transmissioning technology field.
Background technique
The variation of friction clutch is various, but because structure is all comparatively complicated, therefore not being suitable for wind send the orchard spraying device.
The model utility content
The purpose of this utility model is: propose a kind of simple in structure, compact, the friction clutch of reliable performance, thus satisfy the supporting demand that self-propelled wind send orchard sprayer and so on plant protection mechanism.
In order to reach above purpose, friction clutch of the present utility model has the walking pto that is supported on the housing; By spline the supporting base assembly is housed on the described output shaft, and forms axial limiting the supporting base assembly by back-up ring; The friction disk assembly that is made of platen adjacent one another are and friction plate is housed on the described supporting base assembly; One end of described friction disk assembly is adjacent with the positioning screw cap that is fixed on the stop screw, and described stop screw is connected with the base plate that is sleeved on the described output shaft away from an end of positioning screw cap; The spring that makes platen and friction plate produce the trend that is adjacent to is housed between described base plate and the friction disk assembly; Described platen and supporting base are connected, and described friction plate has the external tooth with the fluted disc engagement; Described fluted disc sky is enclosed within on the output shaft and has the moving tooth that extends into the outer between cog of friction plate.
Like this, when utilizing the fluted disc rotation that spline etc. is in transmission connection, will drive supporting holder assembly by the frictional force between friction plate and the platen, and then order about the rotation of walking pto, realize required transmission with the input of outer power.
The utility model further improves, and also is supported with the driving lever with two angular position on the described housing, and the inner extending end of described driving lever stretches into sky and is enclosed within the jacking block on the described output shaft, and an end of described jacking block is resisted against on the end face of base plate; When described driving lever was in first angular position, described spring was in the pretension state, and described platen and friction plate produce the trend that is adjacent to; When described driving lever was in second angular position, described spring was in pressured state, and described platen and friction plate break away from the trend that is adjacent to.
Simple, the reliable transmission of the utility model action, the not thorough phenomenon of clutch can not appear in compact structure, and very suitable high speed power transmission particularly is fit to wind and send the orchard spraying device.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the utility model first embodiment's a structural representation.
Fig. 2 is the side view of Fig. 1.

Embodiment
Embodiment one
Present embodiment is that a kind of wind that is applied in send friction clutch on the spraying device of orchard, its structure as shown in Figure 1, walking pto 1 by bearings on housing 2.By spline supporting base assembly 3 is housed on this output shaft, and by the axial limiting of back-up ring 4 formation to supporting base assembly 3.The friction disk assembly that is made of platen adjacent one another are 5 (4) and friction plate 6 (3) is housed on the supporting base assembly 3.One end of friction disk assembly is adjacent with the positioning screw cap 8 that is fixed on the stop screw 7, and stop screw 7 is connected with the base plate 9 that is sleeved on the output shaft 1 away from an end of positioning screw cap 8.Be equipped with between base plate 9 and the friction disk assembly and be positioned at spring seat 10, make platen 5 and friction plate 6 produce the spring 11 of the trend that is adjacent to.Platen 5 is connected mutually with supporting base 3, and friction plate 6 has the external tooth with fluted disc 12 engagements, and fluted disc 12 skies are enclosed within on the output shaft 1, have the moving tooth (referring to Fig. 3) that extends into friction plate 6 outer between cog.Also be supported with the driving lever 13 with two angular position on the housing 2, the inner extending end of driving lever 13 stretches into sky by shift fork 14 and is enclosed within the jacking block 15 on the output shaft 1, and an end of jacking block 15 is resisted against on the end face of base plate 9 by release bearing 16.When driving lever rotates counterclockwise, when being in first angular position, spring is in the pretension state, makes base plate produce the trend of axial displacement to the right, thereby dwindles spacing between platen and the friction plate by setscrew nut, makes it to produce the trend that is adjacent to; When driving lever clockwise rotates, when being in second angular position, base plate is communicated with setscrew nut axial displacement left, and spring is in pressured state, and the spacing between platen and the friction plate strengthens, thereby breaks away from the trend that is adjacent to.
During work, the power of fluted disc drives the rotation of multi-disc friction sheet.Because the effect of initial tension of spring, friction plate and platen produce frictional force, thereby drive the rotation of friction disk assembly, and the friction disk assembly drives the rotation of pto assembly by the supporting base spline again.When needing clutch to realize separating action, external force affects driving lever, driving lever drives the shift fork rotation, make jacking block and release bearing move to left along the pto direction, be with base plate to move, spring is shortened, thereby friction plate and platen spacing are separated from each other after strengthening with stop screw, friction plate idle running realizes separating.
Theory and practice proves, the pure mechanical clutch of present embodiment, and action is simple, reliable, even sordid situation can not appear separating in long-term work yet, the while compact structure, the wind that is highly suitable for the high speed transferring power send the orchard spraying device supporting use.
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
