Abstract
The invention discloses a coupler on an escalator or a moving sidewalk. The coupler comprises a first semi-coupler, a second semi-coupler and a plurality of cushion blocks which are matched, wherein the cushion blocks are arranged between a convex claw on the first semi-coupler and an inner ring lug boss or an outer ring lug boss on the second semi-coupler. Flexible cushion connection between a motor and a speed reducer is realized through the cushion blocks; and the cushion blocks have the advantages of reducing vibration and absorbing energy, reducing impact noise during starting the motor, reducing the impact on the motor when the escalator or the moving sidewalk brakes or load suddenly changes, prolonging the service life of products and guaranteeing steady and high-efficiency operation of the escalator or the moving sidewalk.
Description
Technical field

Summary of the invention
The coupling that the purpose of this invention is to provide band buffering on a kind of escalator or the moving sideway.
For achieving the above object, the technical solution used in the present invention is: the coupling on a kind of escalator or the moving sideway, comprise first half-coupling that matches, second half-coupling, described first half-coupling is along upwards having a plurality of spaced dogs its week, described second half-coupling is along upwards having a circle groove its week, the inner ring cell wall of described groove, the outer ring cell wall is all towards the internal protrusion of described groove, at described inner ring cell wall, form a plurality of circumferential spaced inner ring projections on the cell wall of described outer ring respectively along described groove, the outer ring projection, a described inner ring projection is corresponding with the position of a described outer ring projection, form containing space between corresponding described inner ring projection in position and the described outer ring projection, described coupling also comprises a plurality of cushion pads, each described cushion pad has intermediate thin portion, extended two thick ends from the described intermediate thin portion, form two host cavities laying respectively at described intermediate thin portion both sides between described intermediate thin portion and described two the thick ends, described intermediate thin portion is inserted in the containing space between described inner ring projection and the described outer ring projection, described inner ring projection and described outer ring projection lay respectively in described two host cavities, and described thick end and described inner ring projection and described outer ring projection are in contact, in a described circle groove, form slot between adjacent two described cushion pads, described dog is inserted in the described slot, and described dog contacts with the thick end of adjacent described cushion pad.
Preferably, described cushion pad is a block rubber.
Because the utilization of technique scheme, the present invention compared with prior art has following advantage: first half-coupling and second half-coupling are separately fixed at motor output shaft, on the speed reducer input shaft, by inner ring projection on the dog on first half-coupling and second half-coupling or the cushion pad between the projection of outer ring, realize that motor is connected with buffering flexible between the speed reducer, cushion pad can the damping energy-absorbing, impact noise when reducing electric motor starting, when the braking of escalator or moving sideway or load change suddenly, cushion pad can also reduce the impact to motor, improve product working life, guarantee the steadily efficient operation of escalator or moving sideway.
