Description
Technical field
This utility model belongs to elevator technology field, especially relates to a kind of shock-absorbing type roller group.
Background technology
It is the most all to use flat side wheel to lead boots, i.e. unilateral roller, unilateral slide block, lead boots for combined rolling,
Roll and use iron core+rubber plastic outer ring mode.This advantageously reduces elevator running noises, also extends the use longevity leading boots
Life.Roller be that line face contacts in the contact theory of guide rail, single boots of leading bear the power of about 2.6kN.And household ladder needs long-time
It is parked in base station, can make to lead boots roller a certain contact line and be chronically at stress, cause the rubber and plastic in roller contact face to there is deformation
Risk.Elevator, once operation, arises that periodically vibration, affects boarding comfortableness.
In order to improve prior art, people have carried out long-term exploration, it is proposed that various solutions.
Such as, Chinese patent literature discloses a kind of shockproof roller guide shoe [application number: CN201420090742.3], including shoe,
One roller, the second roller and the 3rd roller, damping, it is characterised in that: described shoe includes shoe vertical and shoe water
Plane, described shoe horizontal plane is provided with column, and described 3rd roller is fixed on column by the 3rd fork, described first rolling
Wheel and the second roller are fixed on shoe vertical by the first fork and the second fork respectively, described first roller and the second rolling
Wheel is in same plane, and plane residing for this plane and the 3rd roller is perpendicular, and the axle center of above three roller is triangularly arranged,
And breach with shoe is corresponding between above three roller, this breach for through cage guide, described first fork, second
Fork and the 3rd fork are fixed on shoe horizontal plane by standing screw, and described standing screw is provided with damping, institute
State damping be located at below fork with shoe horizontal plane above, described damping can be cut down fork and rock the machinery caused
Power.
Although such scheme to some extent solves the deficiencies in the prior art, but structure is complex, is to pass through
Damping abatement fork rocks the mechanical force caused to realize damping, or draws after the rubber and plastic deformation in unresolved roller contact face
The problem of the periodic vibration risen.
Utility model content
The purpose of this utility model is for the problems referred to above, it is provided that a kind of reasonable in design, simple in construction, it is possible to reduce elevator
The shock-absorbing type roller group of vibrations during startup.
For reaching above-mentioned purpose, this utility model have employed following technical proposal: this shock-absorbing type roller group, is arranged on and leads boots
On plate, including be positioned at centre intermediate roller, described intermediate roller be respectively provided on two sides with side wheel, described intermediate roller
Being located along the same line with the center of circle of side wheel, the diameter of described intermediate roller is more than the diameter of side wheel, described centre
Distance between lower surface and the lower surface of side wheel of roller is buffer distance, and described buffer distance is 5-15mm.
Deformation region contacts guide rail if cage operation front wheel deforms, after car brings into operation, on each roller
Time bearing capacity weaken, make car have the trend of vibration.Owing to intermediate roller and side wheel have a different-diameter, and linear velocity phase
With, if the side wheel deformed region of intermediate roller deformation region contacts guide rail and both sides is then weakened not in contact with guide rail, vibration.When
The wheel footpath of intermediate roller is 90mm, and when the wheel footpath of side wheel is 80mm, 90% vibration is weakened.
In above-mentioned shock-absorbing type roller group, described intermediate roller includes first wheel, outside described first wheel
It is socketed with the first roller rubber on surface, described first wheel has the first groove for the first roller rubber location.
In above-mentioned shock-absorbing type roller group, described side wheel includes the second wheel hub, the appearance of the second described wheel hub
It is socketed with the second roller rubber on face, the second described wheel hub has the second groove for the second roller rubber location.
In above-mentioned shock-absorbing type roller group, the first described roller rubber and the second roller rubber are ring body, and
The maximum deformation quantity of one roller rubber and the second roller rubber is less than 5mm.Maximum deformation quantity is less than 5mm, to limit amplitude.
In above-mentioned shock-absorbing type roller group, the first described roller rubber and the thickness of the second roller rubber are 6-
10mm, the first described groove and the degree of depth of the second groove are 1-5mm.
In above-mentioned shock-absorbing type roller group, described buffer distance is 10mm.
In above-mentioned shock-absorbing type roller group, the wheel footpath of described intermediate roller is 90mm, the wheel footpath of described side wheel
For 80mm.
Compared with prior art, the advantage of this shock-absorbing type roller group is: owing to intermediate roller and side wheel have not
Same diameter, and linear velocity is identical, if intermediate roller deformation region contacts guide rail and the side wheel deformed region of both sides are not in contact with leading
Rail, vibration is then weakened.When the wheel footpath of intermediate roller is 90mm, when the wheel footpath of side wheel is 80mm, 90% vibration is weakened.
