Description
Technical field
The utility model relates to a kind of high elasticity spring pin coupling.
Background technique
Elastic coupling flexible coupling is the flexible coupling with damps torsional vibrations function, is the important connecting piece that connects varied complete sets of equipment transferring power, and numerous forms in different poses and with different expressions are arranged.
Up to now, remain the elastic dowel pin shaft coupling of the nonmetal elastic element form of outmoded backwardness in the active service equipment above 80 percent elastic coupling flexible coupling.Its representative type as shown in Figure 1, it is made up of two flanges and one group of pin, this group pin is the compound pin of nylon pin or rubber and steel formation normally.Because nonmetallic material have limited, easy aging damaged, the unfavorable factors such as transmission efficiency is low, the high low temperature high speed operation of incompatibility of bearing capacity, many important high speeds, heavily loaded occasion are had to abandon for the pursuit of torsional oscillation damping capacity and are adopted as shown in Figure 2 the gear coupling that does not possess the elastic buffer ability.
Gear coupling utilizes a pair of number of teeth, modulus, the inside and outside gear fit of the identical involute of standard pitch circle and the formative gear coupling, it utilizes the sideshake between the inside and outside gear, form the flexible of coupling, produce swing and slip between the inside and outside flank of tooth, the theme equipment of serving for coupling provides axially, angle, radial displacement (be equipment axis dynamically misalign displacement) compensation.
Because the backlash of the common flute profile gear coupling of single-unit is very little, except can making satisfied axial displacement compensation, its angular displacement that can make compensation, radial displacement compensation are very little:
Suppose that backlash is e; The facewidth is of a size of B.
Then the radial displacement of the common flute profile gear coupling of single-unit compensates Δ Y=e;
The angular displacement compensation ΔΦ=arc ten[e/B of coupling];
Angular displacement compensation=Δ the X of coupling.
In order to obtain the compensation of satisfied a little radial displacement compensation and angular displacement, have to the engaging gear coupling is changed into two engagement joint gear couplings.Make that above-mentioned radial displacement compensation rate obtains to be multiplied:
The centre distance of supposing two toothed couplings be L=4B. then:
The radial displacement compensation Δ Y=4e of two engagement joint cydariform flute profile gear couplings;
Axial displacement compensation=2 Δ X of two engagement joint ordinary gear coupling.
In order to obtain the compensation of satisfied more radial displacement compensation and angular displacement, again full depth tooth is transformed into crowned teeth, make angular displacement compensation rate and radial displacement compensation rate obtain increase by a larger margin.
In sum, gear coupling relies on the slip between the inside and outside wheel tooth wheel surface to carry out bit shift compensation.Consider from offset angle, the compensation ability of coupling is directly proportional with mobility, yet there is the deadly defect of this class coupling just of sliding in the work, sliding friction causes temperature rise to cause that flank of tooth gummed destroys, and must adopt steel for carburizing and through the high quality gear on over carburizing, quenching grinding crowned teeth surface.Also must ensure cooling fully and lubricated to the hard flank of tooth.Can not lubricate cooling action and the unavoidable greasy filth problem that produces with ointment, seriously reduced Utilization ratio and efficient; With thin oil cooling, lubricated, increased supplementary equipment investment and structural complexity again, make the cost that belongs to higher-priced carburizing/quenching/grinding/crown gear coupling originally raised without restriction further.The more fatal shortcoming of gear coupling is: inside and outside toe joint touches and belongs to " confronting the tough with toughnees " " zero buffering " transmission, neither possesses damping axial float ability and does not also possess the damps torsional vibrations ability.When being used to have the theme equipment of impulsive load, can seriously reduce service life of equipment.
Nearly 40 years, flexible disc coupling (as shown in Figure 3) and lamination diaphragm flexible shaft coupling (as shown in Figure 4) emerge, its relies on the resiliently deformable of metallic material to provide suitable flexible, has the torsional oscillation damping capacity, can exempt under the lubricating condition tranquil, efficiently, reliably, no failure operation and favored by engineering circle all the year round, be considered to third generation main flow coupling, yet above-mentioned dish, sheet coupling also suffer from a series of strong resistances in challenge, expose following significant deficiency:
1. be known as " zero idle running " high transmission accuracy flexible coupling.Dish, sheet coupling have the limited capability of axial elasticity compensation ability and damping axial float, yet exaggerate artificially is that dish, sheet coupling not only possess " zero idle running " high transmission accuracy but also possess vibration damping/absorbing/vibration isolation ability, even play up to possessing the buffer capacity of torsional oscillation damping.General knowledge is told us: " zero idle running " i.e. is " zero buffering ", since dish, sheet coupling belong to " zero idle running " high transmission accuracy coupling, it just can not possess the buffer capacity of vibration damping/absorbing/vibration isolating effect and damps torsional vibrations again.
2. the axial displacement of dish, sheet coupling compensation weakens the bearing capacity of coupling very sensitively, and dish, the sheet coupling of single engagement possesses the angular displacement compensation ability but do not possess the radial displacement compensation ability.So dish, sheet coupling MANUFACTURER require the user to adopt two engagement systems and require the user to carry out the axial precompensation of trouble for dish, sheet coupling.This makes many users have to rethink would rather to use gear coupling instead and abandons employing dish, sheet coupling.
3. the diameter dimension of flexible disc coupling is too big, and the border line speed under heavy duty/high-speed condition is very easy to break through velocity of sound and makes transmission efficiency low.
4. the cost of flexible disc coupling is too high, and homemade annular flexible laminated membrane coupling is limited to material specification, and bearing capacity is lower than 6.3tm, and is far apart greater than 100tm with tooth-like bearing capacity.
