Description
Technical field
The invention belongs to the transmission device field, particularly a kind of bulging tooth angle is to flexible coupling.
Background technique
The drum toothed coupling is that a kind of diameter of axle is thick, by tooth interlock connection active machine and by motivation, and the king-sized coupling of middle transmission power.Rotate because the drum toothed coupling is the gear interlock, and have thick, the high-power characteristics of the diameter of axle, so it is very big vibration to occur when work, the drawback that noise rings especially.When gear connects rotation, because power is big, vibration force is big, often find initiatively machine with by the axle of motivation, axially movable phenomenon occurring, is rigidity hardware contact break-in because gear rotates, when the active machine and by the axle of motivation, either party occurs moving axially, the capital makes the strength of gear that moves axially one side, and enhance faster wear reduces the working life of gear coupling.
Though the drum toothed coupling has short, drawbacks such as vibration force is big, noise height service life, but because it has characteristics such as the diameter of axle is thick, transmitted power is big, it is again one of indispensable structure in the main equipment, therefore, the defective of rousing toothed coupling is still pendulum needs a great problem that overcomes in the assembling of whole world substantial equipment.
At above-mentioned situation, exigence those skilled in the art develop a kind of novel coupler that can remedy existing drum gear coupling deficiency.
Summary of the invention
In order to overcome the defective of prior art, the present invention proposes a kind of bulging tooth angle to flexible coupling, that this coupling can be adjusted automatically, controls and compensate is main, by the moving axially and the angle skew of motivation, makes the degree of wear of face of gear be reduced to minimum.
The present invention is achieved by the following technical solution:
A kind of bulging tooth angle is to flexible coupling, this coupling comprises the master, by motivation end half-coupling and drum gear coupling half-coupling, described bulging gear coupling half-coupling is sheathed on by on the motivation end half-coupling and in both pass through, external tooth is meshed, it is characterized in that: this coupling also comprises the angle device, diaphragm group and two butt plates, one side of described angle device is connected with the diaphragm group from inside to outside in turn, butt plate I and active machine end half-coupling, the opposite side of angle device is connected with butt plate II from inside to outside in turn, drum gear coupling half-coupling and by motivation end half-coupling.
Wherein, described angle device comprises cross axle and two lands; Described cross axle comprises that pump nozzle and symmetry are located at four hollow shafts of pump nozzle four ends, four hollow shafts and pump nozzle formation decussate texture, and the end of four hollow shafts is arranged with needle bearing respectively; Be respectively equipped with two lugs on the relative one side of described two lands, four lugs corresponding respectively be sheathed on four needle bearings of hollow shaft end; By pump nozzle oiling in four hollow shafts, be lubricated with this each needle bearing to the hollow shaft end.
Wherein, the outside of described each needle bearing seals by catch and check ring respectively.
Wherein, described active machine end half-coupling comprises a connecting sleeve and is arranged on the flange plate of a connecting sleeve one side, described diaphragm group is connected with a land of angle device by bolt I, nut I with butt plate I, and described butt plate I is connected by hexagon socket head cap screw with the flange plate II of active machine end half-coupling.
Wherein, be arranged with a cushion collar on the described bolt I.
Wherein, described bulging gear coupling half-coupling comprises a connecting sleeve and is arranged on the flange plate of a connecting sleeve one side, described butt plate II is connected by hexagon socket head cap screw with another land of angle device, and described butt plate II is connected with the flange plate of drum gear coupling half-coupling by bolt II, nut II.
Wherein, describedly comprised a connecting sleeve by motivation end half-coupling, the outer wall of this connecting sleeve is provided with external tooth, and the axle connecting sleeve inwall of described bulging gear coupling half-coupling is provided with the internal tooth that matches with external tooth, and is meshed with external tooth by this internal tooth.
Wherein, described diaphragm group is overlapping diaphragm group, its be by two-sided rivet with each elastic sheet cross-under, make by hydraulic rain again.
Beneficial effect of the present invention is:
1, in order to prolong the working life of bulging toothed coupling, the present invention has added the structure of diaphragm group, can make machine initiatively and be in operation and adjust distance between the diaxon automatically by motivation, can compensate generation in service move axially and angle is offset, it is more stable, reliable to turn round.When particularly this diaphragm group adopts overlapping diaphragm group, make coupling under the identical situation of the diameter of axle, rated torque is higher by 50% than other diaphragm coupling, and the transmitted power moment of torsion is big, reduces inrush current power, friction, and noise free can prolong 4-5 working life doubly.
2, because the angle drift rate of existing drum gear coupling is 3 °, but the angle drift rate of diaphragm group is 1 °, for the diaphragm group can be applied in the bulging gear coupling, the present invention has increased the structure (its angle drift rate is 3 °) of angle device, can compensate difference between bulging gear coupling and the diaphragm group by this angle device, the diaphragm group can be applied among the present invention smoothly.
3, coupling of the present invention not only can adjust automatically, control and compensate main, by the moving axially and the angle skew of motivation, make the degree of wear of face of gear be reduced to minimum; Can also reduce initiatively machine and the vibration that is produced by the motivation transmission, reduce noise, increase the effect in working life of drum tooth, reach the purpose of energy-saving and environmental protection thereby play.
