Abstract
The utility model relates to a high-elastic coupler of a rotary drilling rig. The high-elastic coupler of the rotary drilling rig comprises a flange plate, a rubber disc, an outer shaft sleeve, a locking bolt and an inner shaft sleeve. The flange plate is connected with an engine flywheel through a bolt, the outer shaft sleeve and the inner shaft sleeve are fixedly installed on a main shaft of a transfer case through the locking bolt, and the flange plate is connected with the outer shaft sleeve through the rubber disc. The high-elastic coupler of the rotary drilling rig has the advantages that the high-elastic natural rubber disc is adopted so that vibration and shock of an engine can be absorbed well and the danger of generating resonance can be avoided, the design that the inner shaft sleeve and the outer shaft sleeve are matched in a conical surface mode is adopted so that connections of shafts are safe and reliable, the influence caused by changing load on the transfer case, the engine and shafting is reduced, the working performance of a transmission system is ensured, and the service lives of the engine and the transfer case are prolonged.
Description
Technical field
The utility model relates to a kind of rotary drilling rig, relates in particular to the high-elastic coupling of a kind of rotary drilling rig.
Background technique
The output of large-scale rotary drilling rig engine power is to be connected with transfer case through coupling, and transfer case is connected with oil hydraulic pump again, and the rotating speed that large-scale rotary drilling rig coupling is born is higher, and moment of torsion is bigger, and rotating speed, change in torque are big, and impact is stronger.The traditional rigid coupling can not effectively reduce the influence of fluctuating load to transfer case, motor and axle system, and compensate the displacement that causes thus very harsh with the stationarity requirement in the diaxon.The fluctuating load of axle system is bigger to the hydraulic system performance impact, if can not well eliminate, often makes the machine can't proper functioning.
Summary of the invention
The utility model technical problem to be solved is: provide a kind of rotary drilling rig high-elastic coupling; Connect motor and transfer case main shaft; The various vibrations and the impact that utilize the high elasticity of high-elastic coupling to come absorption system; Protect motor and transfer case axle system, thereby guarantee the stable output of power.
The utility model is that the technological scheme that problem adopted of the above-mentioned proposition of solution is:
The high-elastic coupling of a kind of rotary drilling rig; Comprise flange plate 1, rubber disc 2, external axle sleeve 3, lock bolt 4, internal axle sleeve 5; Flange plate 1 is connected through bolt with engine flywheel; Internal axle sleeve 5 is fixedly mounted on the transfer case main shaft through lock bolt 4 with external axle sleeve 3, connects through rubber disc 2 between flange plate 1 and the external axle sleeve 3.
Described flange plate 1 is preferably aluminium matter flange plate.
Described rubber disc 2 is preferably the natural rubber dish.
The conical surface of described internal axle sleeve 5 and external axle sleeve 3 cooperatively interacts.
The beneficial effect of the utility model is: employing has elastomeric natural rubber dish and can be good at absorbing engine luggine and impact, and can avoid producing the danger of resonance; Adopt the exterior and interior axle sleeves design of cone match to make the connection of axle more safe and reliable; Reduce the influence of fluctuating load, guarantee the service behaviour of transmission system, prolong the working life of motor and transfer case transfer case, motor and axle system.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Wherein, 1-flange plate, 2-rubber disc, 3-external axle sleeve, 4-lock bolt, 5-internal axle sleeve.
Embodiment
Further specify the embodiment of the utility model below in conjunction with accompanying drawing.
Referring to Fig. 1; The high-elastic coupling of the described a kind of rotary drilling rig of this embodiment; Comprise aluminium matter flange plate 1, natural rubber dish 2, external axle sleeve 3, lock bolt 4, internal axle sleeve 5; Aluminium matter flange plate 1 is connected through bolt with engine flywheel, and internal axle sleeve 5 and external axle sleeve 3 that the conical surface cooperatively interacts are fixedly mounted on the transfer case main shaft through lock bolt 4, connects through natural rubber dish 2 between aluminium matter flange plate 1 and the external axle sleeve 3.
The beneficial effect of this embodiment is: employing has elastomeric natural rubber dish and can be good at absorbing engine luggine and impact, and can avoid producing the danger of resonance; Adopt the exterior and interior axle sleeves design of cone match to make the connection of axle more safe and reliable; Reduce the influence of fluctuating load, guarantee the service behaviour of transmission system, prolong the working life of motor and transfer case transfer case, motor and axle system.
