Embodiment
The attachment structure of the rotary cultivator is by output shaft of gear-box 1, adpting flange 2, flange sleeve 3, shading ring and the structure of gland 4
Into:Output shaft of gear-box 1 is tapered shaft, and flange sleeve 3 is fixed with by way of swelling on output shaft of gear-box 1.
The endoporus of flange sleeve 3 is tapered, and the endoporus of flange sleeve 3 is corresponding with the profile of output shaft of gear-box 1.To flange sleeve
3 when being assembled, and flange sleeve 3 need to be heated to certain temperature, make its expanded by heating, flange sleeve 3 then is plugged into speed change
On case output shaft 1;Make the natural cooling of flange sleeve 3.In the natural cooling process of flange sleeve 3, flange sleeve 3 progressively tighten so as to change
Fast case output shaft 1 forms one.When needing safeguard replacing to flange sleeve 3, it is only necessary to which flange sleeve 3 is heated to certain temperature
Degree, when making 3 expanded by heating of flange sleeve, striking lower flange set 3 can change to it.The purpose that flange sleeve 3 is arranged such is existed
In:Flange sleeve 3 is packed on output shaft of gear-box 1 using the principle expanded with heat and contract with cold, makes it during moment of torsion is transmitted, is become
The problem of fast case output shaft 1 and flange sleeve 3 are not in loosening, when transmitting moment of torsion so as to solve conventional spline, the mill that has
Damage is fast, service life is short and the problem of maintenance difficult.
Gland 4 is fixed with the gear box of the side of flange sleeve 3, interval shape is provided with multiple dresses in the endoporus of gland 4
With annular groove, activity in annular groove of assembling is equipped with shading ring;Shading ring is fastened by two isolation semi-rings 7 and formed;The fastening of each shading ring
Mutually stagger in face 8.The purpose that the buckling surface 8 of shading ring staggers is:When preventing that each buckling surface 8 is in the same plane, mud
Slurry and moisture content can enter transmission internal along each buckling surface 8, and then influence the normal use of bearing.
Isolation semi-ring 7 is made up of basic semi-ring 9 and sealing ring tooth 10;Set on the inner ring surface of basic semi-ring 9 by symmetry shape
The mounting ring 11 put is installed with sealing ring tooth 10.The purpose for installing sealing ring tooth 10 by the symmetry shape of mounting ring 11 is:So that
Two sealing ring teeth 10 are set on one basic semi-ring 9, because sealing ring tooth 10 has sealing function, so that a basis half
Ring 9 forms two seals, and then enhances the sealing effectiveness of isolation semi-ring 7.
The sealing ring tooth 10 of shading ring is slidably connected with output shaft of gear-box 1;Sealing ring tooth 10 is made up of copper material, will
Sealing ring tooth 10 is using purpose made of copper material:Using the softer characteristic of copper material, prevent it from scratching gearbox
Output shaft 1.
Isolation annular groove 12 is provided with the inner ring end face of sealing ring tooth 10.The purpose that sealing ring tooth 10 is arranged such is existed
In:First, output shaft of gear-box 1 during work is set to form a seal cavity with isolating annular groove 12, because output shaft of gear-box 1 exists
Heat can be produced in rotation process, when the heat is gathered in seal cavity, the internal pressure of seal cavity can be made to be pressed higher than extraneous
By force, so that extraneous moisture content or other impurities is difficult to enter in seal cavity, good sealing effectiveness is served.Second, every
Both sides side from annular groove 12 is slidably connected with output shaft of gear-box 1, and both sides side is provided with sealing function, further enhances
The sealing effectiveness of sealing ring tooth 10.
The opposite side of flange sleeve 3 is bolted to connection with the adpting flange 2 being packed on tool roller axis 5.
Dust cover 6 is fixed with the flange sleeve 3 of the side of gland 4, the end face of gland 4 is provided with dustproof groove, and dust cover 6 is with preventing
Dirt groove is rotated and is connected together.In the course of work, dust cover 6 can rotate together with output shaft of gear-box 1 and flange sleeve 3;So
After setting, the contact portion of gland 4 and output shaft of gear-box 1 can be isolated from the outside and come by dust cover 6, and having prevents that the external world is miscellaneous
The purpose that matter enters.
The attachment structure of the rotary cultivator is simple in construction, ingenious in design, that is, solves existing attachment structure and connected using spline
The problem of quick abrasion and short service life that mode has, solve the problems, such as that existing sealing means have poorly sealed again,
It is particularly suitable for the use of rotary cultivator, meets the needs that people use.
