Abstract
A staircase roller capable of preventing traverse gap operation belongs to the technical field of step chain transmission machinery for escalators. The staircase roller rolls on a track, 2 to 6 circular arc-shaped ring grooves are formed on the outer cylindrical surface of the staircase roller. The staircase roller adopts the structure which is quite simple, but the circular arc-shaped ring grooves are additionally formed on the surface of the roller, so that the transversal motion during roller operation is increased and the transverse deflection of the operation track of the roller can be effectively limited, and further the problems of impacts from chain wheel powder delivery, dejacketing and the like on the normal operation of the elevator, which is caused by the inconsistency of operation tracks of a bearing and a stock due to transverse swing of the chain roller during the operation of the elevator, can also be effectively limited. The relative gap operation of the roller and the surface of the track can be achieved in a way that grooves are formed on the surface of the wheel, so that track surface self cleaning can be achieved, the service life of the roller is prolonged, and problems such as bumps, noises and the like as a result of foreign objects entering into the combined surface of the roller and the track can be structurally controlled and protected.
Description
Technical field
The utility model relates to a kind of staircase roller that prevents the traversing running of misunderstanding each other, and it belongs to escalator step chains gearing technical field.
Background technology
At present, the escalator roller is relative with the orbit plane zero-clearance to turn round, be prone to the horizontal beat phenomenon of roller running track, and then cause the running orbit of bearing and hub inconsistent because of the teeter of chain roller when elevator moved, then producing problems affect elevators such as sprocket wheel powder delivery and shelling normally moves, roller is relative with the orbit plane zero-clearance to turn round, can't reject dust and dirt and foreign matter that running process of elevator declines in orbit, because foreign matter enters the faying face of roller and track, thus cause when moving to elevator jolt, problem such as noise.
Summary of the invention
In order to solve above-mentioned problems of the prior art, the utility model provides a kind of staircase roller that prevents the traversing running of misunderstanding each other.The chain roller was not laterally swung when this staircase roller should make the elevator operation, made bearing consistent with the running orbit of hub, steady, noiseless when allowing the elevator operation.
The technical solution adopted for the present invention to solve the technical problems is: a kind of staircase roller that prevents the traversing running of misunderstanding each other, this staircase roller rolls in orbit.The external cylindrical surface of described staircase roller is provided with 2～6 circular arc annular grooves.
Described circular arc annular groove adopts circular arc as groove structure.
Wide a=1.0～the 2.0mm of the annular groove of described circular arc annular groove, the dark b=0.2～0.5mm of annular groove.
The beneficial effects of the utility model are: this prevent traversing misunderstand each other the running the staircase roller roll in orbit, on the external cylindrical surface of staircase roller, be provided with 2～6 circular arc annular grooves.The structure that this staircase roller adopts is very simple, but because roller surface has increased several circular arc annular grooves, roller running side travel resistance increases, can actv. the horizontal beat of restriction roller running track, and then cause the running orbit of bearing and hub inconsistent because of the teeter of chain roller when elevator moved, producing sprocket wheel powder delivery and shelling etc. then influences problem such as the normal operation of elevator and carries out actv. and limit.Add the relative running of misunderstanding each other of roller that groove realizes and orbital plane by wheel face, can conclude, and commutate to dally at chain and rejected dust and dirt and foreign matter etc. that running process of elevator declines in orbit.Can reach the automatically cleaning orbital plane thus, increase the service life of roller, jolt when also bringing elevator to move simultaneously, problem such as noise accomplishes structural control and protection the faying face that enters roller and track because of foreign matter.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is that a kind of axle of the staircase roller of the traversing running of misunderstanding each other that prevents is surveyed the signal working state figure.
Fig. 2 is a kind of structure front elevation that prevents the staircase roller of the traversing running of misunderstanding each other.
Fig. 3 is the A enlarged drawing among Fig. 2.
Among the figure: 1, track, 2, the staircase roller, 3, the circular arc annular groove, 3a, circular arc.
The specific embodiment
Fig. 1,2 shows a kind of constructional drawing that prevents the staircase roller of the traversing running of misunderstanding each other.Among the figure, staircase roller 2 rolls on track 1, and the external cylindrical surface of staircase roller 2 is provided with 3 circular arc annular grooves 3.
Fig. 3 shows the A enlarged drawing among Fig. 2.Among the figure, circular arc annular groove 3 adopts circular arc 3a as groove structure.Aborning, as long as choose form cutter, just can very on the external cylindrical surface of staircase roller 2, process the circular arc annular groove 3 of requested number easily.The wide a=1.5mm of annular groove of diagram circular arc annular groove 3, the dark b=0.25mm of annular groove.
Claims (3)
1. one kind prevents the traversing staircase roller of misunderstanding each other and turning round, and this staircase roller (2) is gone up at track (1) and rolled, and it is characterized in that: the external cylindrical surface of described staircase roller (2) is provided with 2～6 circular arc annular grooves (3).
2. according to the described staircase roller that prevents the traversing running of misunderstanding each other of claim 1, it is characterized in that: described circular arc annular groove (3) adopts circular arc (3a) as groove structure.
3. according to the described staircase roller that prevents the traversing running of misunderstanding each other of claim 1, it is characterized in that: the wide a=1.0～2.0mm of annular groove of described circular arc annular groove (3), the dark b=0.2～0.5mm of annular groove.
