Description
Technical field
The present invention relates to a kind of coupling, be specifically related to a kind of elastic steel-needle pin coupler.
Background technique
Coupling is the ubiquity every field because different working environments, make coupling with different performance index from satisfying various device requirement objectively.
Since the device fabrication error, the load metamorphism in alignment error and the work, factors such as temperature distortion, inevitably having a certain amount of misaligning between the main driven shaft that coupling connect is that radial axis skew, axis angle are to skew, axis axial dipole field.The adaptable ability of coupling is referred to as compensation.When the compensation of coupling within the scope that will compensate, coupling just can run well, otherwise coupling can not run well, with can not the run well additional load that just made increase that machinery exceeds the quata of coupling, additional load surpasses more than 10 times when serious, force the violent vibrations of machinery, bearing wear takes place, rapture of oil seal, axle journal burns, the parts local fracture, even some row serious consequences such as the disconnected lower margin fixing bolt of shake, so the function of coupling be can be safe and reliable transmitting torque, again can be with enough flexible three skews that misalign that adapt between two axial lines, additional overload and the vibrations of avoiding machinery to exceed the quata.
A kind of traditional elastic dowel pin shaft coupling is at the pin outer periphery rubber sleeve of its steel, during work, initiatively arbor acts on the initiatively torque of flange, with the form of peripheral force through pin rubber sleeve and driven flange, pass to driven arbor, and realize the offset compensation that misaligns on the axis with small resiliently deformable of rubber sleeve and rubber sleeve in the slip on the circular hole wall that matches.
Another kind of traditional elastic dowel pin shaft coupling, by the active flange, pin and driven flange and baffle plate are formed, and pin can be made with nylon or rubber, has the ability that misaligns on transmitting torque and the compensation axis concurrently.
Above-mentioned two kinds of traditional elastic dowel pin shaft couplings, its common ground is simple in structure, compact dimensions is cheap, easy to maintenance, nose balance is big, by last one-hundred-year history, has been widely used in middle low speed, on the equipment of heavy duty axle system and commonly used system, market covers more than 70%, however rubber, materials such as nylon heat-resisting, wear resistance is poor, aging easily, wear out failure, in high speed, key areas such as high temperature are subjected to the severe challenge of emerging disc couplin, and the subject matter of these two kinds of coupling is: flexible for increasing, and satisfy the needs of compensation ability and the surface of contact of rubber sleeve or nylon pin is reduced, and make the shape of groove, cause bearing capacity to descend.Conversely, satisfy bearing capacity, the area of contact of rubber sleeve or nylon pin is strengthened, then sacrificed the ability of compensation, the artificer can not be satisfactory to both parties and attend to one thing and lose sight of another, and often biases toward bearing capacity and sacrifice compensation ability, cause equipment use in the vibrations aggravation, be that mechanical failure is frequent, manufacturing efficiency reduces.
Also have a kind of being used at a high speed, the gear type coupling that heavy duty is traditional, by back-up ring, external gear, internal gear, lubricated fueling injection equipment and link are formed, because the flank of tooth does not possess elasticity, flexible angle skew and the radial deflection that compensates axis that swing produced that he relies on paired internal gear of suit and external gear driving torque to contact at the flank of tooth simultaneously, again because the gap between tooth and the tooth is very little, when machinery requires radial deflection big, must take extension shaft to satisfy angular compensatory to the spacing of two teeth is quantized into the radial compensation amount and achieves the goal, as seen the axis three-dimensional skew that goes out the gear type coupling finally all concentrates the slip that relies between the flank of tooth to compensate, therefore, the speed of this slip and amplitude may cause the generation of flank of tooth gummed than the high-speed slide of large contact surface.For overcoming at a high speed the gummed tendency to the gear type coupling, the Designer is to the material of coupling gear, geometrical shape, flank of tooth state, lubricated etc. by high requirement.
Also have a kind of spring pin coupling, performance design is reasonable, and bearing capacity is big, but structure is complicated.Because complex structure, manufacture process requirement is higher, and price is higher, accepts being difficult on the normal client price of former use elastic cylinder guide and elastic dowel pin shaft coupling, and influence is promoted.
Summary of the invention
For overcoming deficiency of the prior art, the object of the present invention is to provide a kind of elastic steel-needle pin coupler, this coupling has the compact dimensions of pin-type load coupling, technology is simple, and is with low cost, is easy to safeguard, nose balance, angular compensatory, characteristics such as the radial compensation ability is strong, and this coupling is applicable to occasions such as high temperature, damping, selflubricating.
For solving the problems of the technologies described above, reach above-mentioned technical purpose, the present invention adopts following technological scheme:
