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

Coupling on escalator or the moving sideway

Technical field

The present invention relates to the coupling on a kind of escalator or the moving sideway.

Background technique

On escalator or moving sideway, existing coupling can be referring to Chinese patent literature " a kind of coupling ", publication number CN101699092, open day 2010-04-28, this coupling comprises first half-coupling, second half-coupling that matches, first half-coupling and second half-coupling upwards have a plurality of spaced dogs respectively along its week, form groove between adjacent two dogs, dog on first half-coupling is inserted in the groove on second half-coupling, and the dog on second half-coupling is inserted in the groove on first half-coupling.First half-coupling and second half-coupling are separately fixed on motor output shaft and the speed reducer input shaft, are plugged together by the dog on first half-coupling and second half-coupling with intersecting, realize transferring power between motor and the speed reducer.The escalator moving sideway is a kind of equipment of Fraquent start, be usually to have various self-starting devices on escalator or the moving sideway, just start when promptly passenger demand being arranged, like this can power saving, but cause escalator moving sideway Fraquent start and braking, between motor and speed reducer, adopt existing coupling to be connected, promptly adopt when being rigidly connected, frequent motor starting causes noise big, the impact that the frequent braking of motor and passenger's load change can cause motor to be subjected to is big, and shorten the working life of motor.

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.

Description of drawings

Accompanying drawing 1 is STRUCTURE DECOMPOSITION figure of the present invention;

Accompanying drawing 2 is a part-structure exploded view of the present invention;

Accompanying drawing 3 is a partial sectional view of the present invention;

STRUCTURE DECOMPOSITION figure when accompanying drawing 4 is applied on the motor and speed reducer for the present invention.

Embodiment

Further set forth structure of the present invention below in conjunction with accompanying drawing.

Shown in Fig. 1-4, coupling 1 on a kind of escalator or the moving sideway, comprise first half-coupling 2, second half-coupling 3, a plurality of cushion pad 4 that match, cushion pad 4 is made by rubber material, has elasticity, first half-coupling 2 is connected by key on the input shaft of speed reducer 16, and second half-coupling 3 is connected the output shaft of motor 15 by key.First half-coupling 2 is along upwards having a plurality of spaced dogs 5 its week, second half-coupling 3 is along upwards having a circle groove 6 its week, the inner ring cell wall 7 of groove 6, outer ring cell wall 8 is all towards the internal protrusion of groove 6, at inner ring cell wall 7, form a plurality of circumferential spaced inner ring projections 9 on the outer ring cell wall 8 respectively along groove 6, outer ring projection 10, an inner ring projection 9 is corresponding with the position of an outer ring projection 10, form containing space 11 between corresponding inner ring projection 9 in position and the outer ring projection 10, each cushion pad 4 has intermediate thin portion 12, extended two thick ends 13 from the intermediate thin portion 12, form two host cavities 14 that lay respectively at intermediate thin portion 12 both sides between intermediate thin portion 12 and two thick ends 13, intermediate thin portion 12 is inserted in the containing space 11 between inner ring projection 9 and the outer ring projection 10, inner ring projection 9 lays respectively in two host cavities 14 with outer ring projection 10, and thick end 13 is in contact with inner ring projection 9 and outer ring projection 10, in a circle groove 6, form slot between adjacent two cushion pads 4, dog 5 is inserted in the slot, the thick end 13 of the cushion pad 4 that dog 5 is adjacent with both sides is in contact, like this when motor positive and inverse is realized escalator or moving sideway upstream or downstream, by inner ring projection 9 on the dog 5 on first half-coupling 2 and second half-coupling 3 or the cushion pad 4 between the outer ring projection 10, realize that motor 15 is connected with buffering flexible between the speed reducer 16, cushion pad 4 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 4 can also reduce the impact to motor, improve product working life, guarantee the steadily efficient operation of escalator or moving sideway.
