Description
Technical field
The utility model relates to a kind of Hoisting Machinery parts, especially a kind of gear coupling of improvement.
Background technique
Coupling is used to connect two axles (driving shaft and driven shaft) in different institutions, makes it jointly to rotate with the mechanical part of transmitting torque.Coupling is generally made up of two-part, connects respectively with driving shaft and driven shaft.Because existing coupler structure is complicated, higher to the concentricity requirement between driving shaft and driven shaft, and higher cost also limit the use on some conventional equipments.
Improve in the industry, such as Chinese patent discloses gear coupling, application number: 201220679797.9, the applying date: 2012-12-11, the utility model discloses a kind of gear coupling, comprise coupling body, described coupling body comprises the identical left and right connecting bushing of external diameter, the right-hand member outer surface of described left connecting bushing is welded with Left Drive sprocket wheel, the left end outer surface of described right connecting bushing is welded with right drive sprocket, and described Left Drive sprocket wheel and right drive sprocket are connected as a single entity by the drive chain engaged with it.The utility model has the advantage of that structure is simple, be convenient to assembling, the drive chain be meshed with Left Drive sprocket wheel and right drive sprocket respectively adds the adjusting play of driving shaft and driven shaft, be very applicable to driving shaft and driven shaft concentricity requirement not high time use occasion.
The deficiency of this technological scheme is, because drive chain is directly socketed in two drive sprocket peripheries, add that two original concentricitys of drive sprocket are just not high, in running up, there will be drive chain gradually towards the situation of one of them drive sprocket displacement, severe patient even occurs that drive chain departs from one of them drive sprocket.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of stable operation, the gear coupling of long service life.
The technical solution of the utility model is:
A kind of gear coupling of improvement, comprise driving shaft, driven shaft, driving gear, driven gear, drive chain, it is characterized in that: described driving shaft is connected with driving gear, described driven shaft is connected with driven gear, described driving gear is opposite with driven gear, described driving gear is identical with the structure of driven gear, its effect prevents the gear rotational speed of the different number of teeth or different size and moment of torsion disunity from damaging parts, described driving gear and driven gear periphery are arranged with drive chain and drive chain and driving gear, driven gear engages each other, described drive chain joins end to end, its effect utilizes drive chain driving gear and driven gear to be connected with each other, and have adjustment spaces much more more relative to other rigid couplings or elastic coupling flexible coupling due to drive chain, make to have between driving shaft and driven shaft the angle and concentricity difference that more strengthen, be beneficial to the not high occasion of some concentricity requirement and machinery use, the both sides of described drive chain are evenly provided with some limiting boards, described limiting board comprises main limiting board and from limiting board, described main limiting board is the sheet metal perpendicular to driving shaft that the carrier bar of drive chain extends by driving shaft side, the described sheet metal perpendicular to driven shaft from limiting board being the carrier bar of drive chain and extending by driven shaft side, described main limiting board and from limiting board and carrier bar one-body molded, its effect extends limiting board by drive chain to make drive chain effectively be fixed on two outer peripheral gears in the axial direction, be not subjected to displacement.
Further, described driving shaft and driving gear one-body molded, described driven shaft and driven gear one-body molded, its effect ensures the intensity of coupling.
Further, be provided with dust-proof cover outside described driving gear, driven gear and drive chain, described dust-proof cover is fixed on driving shaft, and its effect is effectively dust-proof under the prerequisite not affecting coupling work.
The beneficial effects of the utility model are: the utility model has the advantage of that structure is simple, be convenient to assembling, the drive chain be meshed with driving gear and driven gear respectively adds the adjusting play of driving shaft and driven shaft, be very applicable to driving shaft and driven shaft concentricity requirement not high time use occasion; The problem of drive chain displacement is efficiently solved additionally by limiting board.
