Abstract
The invention discloses an elevator roller of an elevator landing door system. A section of a metal roller frame is T-shaped; a longitudinal part is in a hollow structure; a limit check ring extending in the radial direction of a through hole is arranged on the through hole orifice edge, on the same side with a transverse part, of the longitudinal part; a metal shaft sleeve is arranged in the through hole of the longitudinal part; the end part of one side of the metal shaft sleeve is in blocking connection with the limit check ring; an annular gap is formed between the outer circumferential surface of the metal shaft sleeve and the inner hole wall of the through hole; multiple pin rollers are distributed in the circumferential direction of the metal shaft sleeve in the annular gap, and each pin roller is parallel to a central axis of the metal shaft sleeve; a non-metal outer ring is connected to the longitudinal part of the metal roller frame in a sleeving manner; a metal backup shoe is further connected onto the longitudinal part of the metal roller frame in a sleeving manner; the metal backup shoe, the metal shaft sleeve and the metal roller frame are riveted through end port of the longitudinal part of the metal roller frame. According to the roller of the elevator landing door system, the technical problem about reduction of the production cost of the elevator roller of the elevator landing door system is solved, and the production cost is low.
Description
Technical field
The present invention relates to a kind of roller accessory, particularly a kind of roller of elevator landing door system.
Background technology
Elevator roller uses very frequent in whole elevator device, is such as used on the door lock assembly of elevator landing door system.
The Elevator roller 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 Elevator roller 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 Elevator roller of whole elevator landing door system relatively high; Secondly, the specification limitation of standard rolling bearing is large, causes the specification of the Elevator roller 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 Elevator roller of the elevator landing door system of above-mentioned existing structure.
Summary of the invention
The object of the invention is the roller 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 roller 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.
The roller 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.
The roller of a kind of elevator landing door system that the present invention obtains, the roller 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.
