Abstract
The invention discloses an elevator roller wheel of an elevator landing door system. The cross section of a metal roller wheel framework is T-shaped, and is of a hollow structure; the orifice of a through hole in a longitudinal part on the same side of a horizontal part is provided with a limiting check ring which longitudinally extends toward the through hole; a metal axle sleeve is arranged in the through hole in the longitudinal part; the end part of one side of the metal axle sleeve is in baffle connection with the limiting check ring; an annular clearance is formed between the peripheric ring surface of the metal axle sleeve and the inner hole wall of the through hole; multiple pin rollers are arrayed in the annular clearance along the peripheric ring direction of the metal axle sleeve; a nonmetal outer ring is in sleeve connection with the longitudinal part of the metal roller wheel framework; a metal pressure cover is also in sleeve connection with the longitudinal part of the metal roller wheel framework; the metal pressure cover, the metal axle sleeve and the metal roller wheel framework are riveted through the end opening of the longitudinal part of the metal roller wheel framework; and through pinholes are formed in the riveting surface so that the annular clearance is communicated with the external environment. The technical problem about how to lower the production cost of the elevator roller wheel of the elevator landing door system is solved, and the production cost is relatively low.
Description
Technical field
The present invention relates to a kind of roller accessory, particularly a kind of lift wheel of elevator landing door system.
Background technology
Lift wheel uses very frequent in whole elevator device, is such as used on the door lock assembly of elevator landing door system.
The lift wheel of current existing elevator landing door system, its structure probably comprises standard rolling bearing, roller shaft bearing and rubber/plastic outer ring, its production technology is as follows: first by rubber/plastic outer ring pressure injection outside roller shaft bearing, be generally the structure that rubber/plastic outer ring entirety exposes, then standard rolling bearing is put into roller shaft bearing, finally standard rolling bearing and roller shaft bearing are riveted.
There is following defect in the lift wheel of the elevator landing door system of said structure: first, and the unit price of standard rolling bearing is relatively high, causes the cost of the lift wheel of whole elevator landing door system relatively high; Secondly, the specification limitation of standard rolling bearing is large, causes the specification of the lift wheel of elevator landing door system to be formulated and there is limitation; Further, the structure design that rubber/plastic outer ring entirety exposes, consider the factor that rubber/plastic outer ring material is relatively soft, it is is easily worn and torn by foreign object.
Therefore, applicant thinks and is necessary to do further structural development to the lift wheel of the elevator landing door system of above-mentioned existing structure.
Summary of the invention
The object of the invention is the lift wheel that a kind of elevator landing door system is provided to solve above-mentioned the deficiencies in the prior art.
To achieve these goals, the lift wheel of a kind of elevator landing door system designed by the present invention, comprise Metal Contact Rollers skeleton and non-metal outer ring, the cross section of described Metal Contact Rollers skeleton is in T shape, and longitudinal component is hollow structure, on described longitudinal component with the openings of lateral part homonymy along being provided with the spacing back-up ring extended to the radial direction of through hole, metal axle sleeve is provided with in the through hole of above-mentioned longitudinal component, one side end of metal axle sleeve and above-mentioned spacing back-up ring keep off and connecing, and form an annular spaces between the face, outer border of metal axle sleeve and the inner hole wall of through hole, direction, border by metal axle sleeve in this annular spaces is placed with multiple roller, and each roller parallels with the axis of metal axle sleeve, non-metal outer ring sleeve is connected on the longitudinal component of Metal Contact Rollers skeleton, and the lateral part of a side and Metal Contact Rollers skeleton keeps off and connecing, the longitudinal component of above-mentioned Metal Contact Rollers skeleton is also socketed with metal backup shoe, metal backup shoe is positioned at the opposite side of non-metal outer ring, above-mentioned metal platen, metal axle sleeve and Metal Contact Rollers skeleton three pass through the port riveted of the longitudinal component of Metal Contact Rollers skeleton, and be provided with on above-mentioned riveted face and realize annular spaces and the through pin hole of external environment condition.
The lift wheel of above-mentioned middle provided a kind of elevator landing door system, without the need to combined standard bearing again in its structure, therefore it manufactures lower relatively, the limitation of the specification of final products is less, and non-metal outer ring is overall built-in between metal backup shoe and the lateral part of Metal Contact Rollers skeleton in its structure, it is is not easily worn and torn by foreign object.Meanwhile, and be positioned at described metal platen in structure, the pin hole on metal axle sleeve and Metal Contact Rollers skeleton three's riveted face can dispel the heat to roller effectively, and the situation avoiding roller to affect rolling characteristics because of fever expansion occurs.
The lift wheel of a kind of elevator landing door system that the present invention obtains, the lift wheel of above-mentioned middle provided a kind of elevator landing door system it to have possessed productive costs relatively low, the limitation of product specification size is little, simultaneously the advantage such as long service life.
