Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Fig. 1 to 2, the preferred embodiment that the utility model provides.
Gear coupling, can be used in hoist accessory,
Gear coupling, include externality shaft 102, ring gear 101 and end cap 103, wherein, ring gear 101 coordinates with externality shaft 102, end cap 103 is positioned at externality shaft 102 two ends, and the gear teeth periphery of ring gear 101 is formed with shock ring 1011, is formed with intermediate shaft hole in the middle of ring gear, axis hole interior edge face is formed with centering treatment device, externality shaft 102 is formed with lubricating fitting.
Axle is arranged in the axis hole of ring gear 101, ring gear 101 is connected with externality shaft 102, the transmission of torque of driving shaft is to driven shaft, the process that diaxon rotates is converted into the deformation of damping device to the impact force produced between ring gear 101 and externality shaft 102, when alignment degree between diaxon does not meet the demands, centering treatment device will carry out centering adjustment to diaxon, in the process of diaxon running, lubricating fitting provides desirable lubricating condition, the phenomenon causing tooth surface abrasion and ring gear cannot engage with externality shaft can be avoided like this, improve the working life of gear coupling.
Particularly, the gear teeth of ring gear 101 include double wedge and recessed tooth, double wedge and recessed tooth are interspersed, all damping trough is formed in the middle of recessed tooth, shock ring 1011 includes damping double wedge and the recessed tooth of damping, damping double wedge and the recessed tooth of damping are interspersed, and be formed with damping projection 1012 in the middle of the recessed tooth inner circumferential of damping, damping projection coordinates with damping trough.
Utilize the structure that damping projection 1012 coordinates with damping trough, difficult drop-off in the process that shock ring operates at diaxon can be ensured, when diaxon operates, the impact force that shock ring will absorb between ring gear and externality shaft, reduce tooth surface abrasion, improve the working life of gear coupling.
Shock ring 1011 is profile of tooth rubber ring, and in practice, shock ring can be other cycle objects, and such as profile of tooth falope ring etc., are not limited to profile of tooth rubber ring.
Centering treatment device includes midline detect sensor, controller and centering regulator, wherein, controller is for judging diaxon whether centering, diaxon can be carried out adjustment centering by centering regulator, midline detect sensor is positioned on axis hole interior edge face, controller is standalone module, and centering regulator is positioned at midline detect sensor side.Utilize centering treatment device, when diaxon operates, detect the alignment degree of diaxon, if when alignment degree does not meet the demands, controller can send signal, carries out adjustment centering after centering regulator Received signal strength to diaxon, the centering degree of diaxon can be detected like this moment, adjust alignment degree efficiently, avoid occurring that ring gear cannot engage with externality shaft, cause the phenomenon that diaxon cannot rotate.
Wherein, centering regulator is flexible rod, and adjusted the alignment degree of diaxon by the distance of stretch out and draw back of flexible rod, structure is simple.
